1: According to the purpose, it can be divided into the following two categories (1) General-purpose special containers, also known as dry cargo containers or general cargo containers, refer to fully enclosed containers with rigid top, side walls, end walls and bottom, and a door on at least one end wall. General-purpose containers are suitable for transporting most general goods. (2) Special-purpose containers refer to general or cargo containers with a common structure for the convenience of loading and unloading goods without end doors, or for special purposes such as ventilation, including ventilated containers, open-top containers, platform containers and channel containers. 2: According to different structures, it is divided into the following 4 types (1) Inner column type special container Its side columns or end columns are located inside the side walls or end walls. The advantages are that the surface is smooth, not easily damaged by oblique external forces, and it is relatively convenient to print logos. There is a space between the outer plate and the inner lining plate, so the heat protection effect is good and the moisture loss rate of the goods can be reduced. When repairing and replacing the outer plate, the box lining does not need to be removed. (2) Outer column type special container Its side columns or end columns are outside the side walls or end walls, so when subjected to external forces, the outer plate is not easily damaged, and sometimes the inner lining plate can be omitted. (3) Folding special container Its main components (side walls, end walls and box top) can be easily folded or disassembled. When used again, it can be easily reassembled. The advantage is that the volume of the box can be reduced during collection and storage, improving the economic effect of transportation. However, since the main components are connected by hinges, their strength is affected. (4) Thin-shell special container Different from the general special container structure (the frame bears the load, and the outer plate of the box is riveted or welded to the frame), all the parts form a rigid body, similar to the aircraft structure. The advantage is that it is light in weight and its whole body can withstand the torque without causing permanent deformation, but the process requirements are high.

As container mobile houses become more and more user-friendly, more and more construction sites choose them as office and living places. In terms of lighting and ventilation, due to the high variability of mobile houses, various ventilation holes can be drilled and installed around the board house at any time.   One of the reasons why container mobile houses have become the first choice for construction sites is that they have a low construction price. Compared with reinforced concrete permanent houses, container houses can save nearly 80% of the cost.   However, its service life can reach 20 years. In addition to its lifespan, the activity performance of container mobile houses is also incomparable to permanent houses.   The container houses introduce advanced modern home design concepts, using steel plates, sandwich panels, bolts, aluminum accessories, concrete, wood, tiles, glass, paint and other materials, and are refined through standard process to form an integrated mobile house.   Containers for living have the characteristics of being ready to use, movable anytime and anywhere, recyclable anytime and anywhere, safe, environmentally friendly, beautiful, economical, fast and efficient.   In addition, containers for living are also environmentally friendly, do not produce any garbage, and will not cause any pollution to the surroundings. It is like a box that can be moved anytime and anywhere.   Container mobile houses were originally mainly used on construction sites. For construction sites, container mobile houses can be a blessing for them. They can be used as dormitories for construction workers, as well as meeting rooms, offices, etc.   Nowadays, global pollution is serious, especially in China. The world has been advocating energy conservation and emission reduction, low-carbon production, and reducing pollution to the environment.   Construction has always been a serious pollution to the environment, such as waste of resources, and a lot of garbage, dust and noise generated during the construction process.   These problems are very headaches for construction units. With container mobile houses, these are small problems. Container mobile houses are very environmentally friendly, they can be recycled and save energy.   And container mobile houses are safe and convenient to build, unlike other houses that require a lot of preparation before building temporary housing. Instead, it is directly hoisted, without any cement, sand, or bricks, saving a lot of resources.   And it can be directly hoisted away after use, without leaving any garbage products, and it can be gone cleanly. The construction and installation time of the container mobile house is very short, saving time and effort. No garbage is generated. It will not affect the surrounding residents during installation.   What are the characteristics of container houses?   1. Standardized size of container houses   The size of container houses is standardized. Since containers need to be transported by sea and land, their external dimensions are strictly limited.   Objectively speaking, the construction of container houses is inseparable from the size of existing containers. Except for the special customization of individual containers, most container sizes are standard and uniform.   2. The structure of container houses is stable and safe   The structure of container houses is stable and safe. The service life of container transportation is 10-15 years. After being eliminated by the transportation industry, those undamaged containers are usually guaranteed to last more than 15 years. When the maintenance conditions are good or used with other structures such as concrete, they can last longer.   3. The economy of container houses   Container houses are widely used all over the world. When containers are transported, existing transportation tools can be used. It can also be easily installed through modular combination during construction, and can even be built by the owner's DIY method;   When it is necessary to re-change the construction site, it is easy to remove the transit by a small amount of disassembly. These characteristics determine the manpower and material resources required for container houses, which reflects its economy.   4. Flexibility of container houses   Compared with traditional building forms, the advantage of container houses lies in the flexibility of construction: when the local area needs to be upgraded, it can be replaced with a new one; when it needs to be demolished, it can be easily dismantled and rebuilt from another place.

In some logistics transportation, the use of some special containers is a new logistics transportation mode. As one of the commonly used logistics transportation methods, what are the advantages of using non-standard special container transportation? Let me introduce it to you today. The use of special container transportation is to assemble goods in large containers to facilitate the loading and unloading of large transportation machines, so as to better realize the "door-to-door" transportation of goods. A new, efficient and cost-effective transportation method. 1: High efficiency of transportation method 1) High loading and unloading power. 2) High utilization rate of transportation tools 3) High capital turnover rate. 4) Save the cost of packaging and transportation. 5) Improve the utilization rate of the warehouse. In short, container transportation improves the efficiency of loading and unloading operations. Since the loading and unloading operations of containers are suitable for mechanization, the efficiency of loading and unloading operations has been greatly improved. At the same time, it greatly shortens the stay time of the container station (port), accelerates the turnover of vehicles and ships and the delivery of goods. 2. High efficiency of transportation mode 1) Simplify packaging and save a lot of packaging costs. 2) Reduce cargo damage and cargo difference and improve freight quality. 3) Reduce operating expenses and transportation costs. Cargo damage and cargo difference are greatly reduced, and cargo insurance premiums also decrease accordingly; after carrying out "door-to-door" transportation business, a lot of warehouse construction costs and warehouse operation costs can be saved. This mode of transportation can better ensure the safety of cargo transportation. Container transportation greatly reduces the number of times of manual loading and unloading and handling in traditional transportation methods, which can avoid cargo damage, moisture damage, loss and other freight accidents caused by human and natural factors, and reduce economic losses 3: High collaboration of transportation mode Container transportation involves a wide range of aspects, many links and great impact. It is a complex transportation system project. The container transportation system includes sea transportation, land transportation, air transportation, ports, freight stations, and units and departments such as customs, commodity inspection, ship agency companies, freight agency companies, etc. related to container transportation. If the cooperation is not appropriate, it will affect the function of the entire transportation system. If a certain link fails, it will inevitably affect the overall situation and even cause transportation production to stop and interrupt. Therefore, it is required to achieve a high degree of cooperation among all links and departments of the entire transportation system. At the same time, under this model, a good cooperative atmosphere among departments is promoted and mutual cooperation among departments is increased. 4: Multimodal transport of transport modes Container transport simplifies freight operation procedures. After the goods are transported in containers, the container is used as the transport unit of the goods, which reduces the complicated operation links and simplifies the freight operation procedures. Since container transport only needs to change containers when changing between different modes of transport, it is not necessary to move the goods in the container, which improves the efficiency of the changeover operation and is suitable for joint transportation between different modes of transport. When changing and transshipping, the customs and relevant regulatory units only need to seal or check the seals for transfer and release, thereby improving transportation efficiency. In summary, container transport has the advantages of high efficiency, high benefit, high collaboration, and multimodal transport compared to traditional transport, and can better realize "door-to-door" logistics transportation.

According to the latest report: At around 13:40 on August 9, a dangerous goods container (category V dangerous goods) in transit on the No. 2 berth of the "Dong Ming" ship (belonging to Taiwan Yang Ming Shipping Company) of Beilun Second Container Terminal Branch caught fire. There are currently no casualties. According to media reports, a shipping insider revealed that the ship was an ocean-going vessel of YML (Yang Ming Marine Transport). "The cargo was a dangerous refrigerated cargo of Class 5.2 peroxidants picked up by HMM Shipping Company, which shared a cabin with YML Shipping Company. When it was bound for the Middle East from Shanghai, the cargo was not plugged in during the transshipment at Ningbo Phase III Terminal, which caused an explosion." At the same time, the insider said that the container was loaded at a constant temperature, but due to the high temperature in Ningbo recently, whether there was improper operation that caused the temperature to rise remains to be investigated. In addition, an initial accident briefing from Yang Ming Marine showed that thick smoke was initially found coming out of a container on the bow deck, and the on-duty personnel immediately notified the first mate and the terminal, after which the fire brigade required all personnel to evacuate to a safe location at the terminal.   oxidizing substances and organic peroxides： Class 5.1 oxidants refer to substances that are in a highly oxidized state, have strong oxidizing properties, are easily decomposed and release oxygen and heat. These oxidants themselves may not be flammable, but can cause the combustion of combustibles; they are more sensitive to heat, vibration or friction.   Class 5.2 organic peroxides are prone to exothermic decomposition at room temperature or high temperature, and some organic peroxides may even decompose explosively under closed conditions.   In the Zhoushan Port explosion, the container involved was loaded with organic peroxides, one of the five types of dangerous goods, which is consistent with the description in many reports.   The accident once again highlights the importance of dangerous goods transportation management, especially in the current hot weather, the safety hazards of dangerous goods such as lithium batteries need to be paid more attention.   Dangerous goods storage and transportation safety： At present, container transportation, as an important part of global dangerous goods logistics, is facing severe challenges in its safety management. For example: If storage is not done properly, containers cannot ensure the safety of dangerous goods storage. Storage in ports and other places is chaotic, rescue is difficult, and secondary explosions are likely to occur. During the transportation of dangerous goods containers, due to their special physical and chemical properties, there is a risk of serious accidents such as leakage, explosion, and corrosion, which poses a huge threat to crew members, other goods and the marine environment.   Dangerous goods transportation requires professional technology and knowledge, but there is a lack of relevant talents in the market.   The explosion highlights the importance of using special containers to transport dangerous goods. Special containers have special designs and functions to ensure the safety and compliance of dangerous goods during transportation. These containers must meet a series of special requirements in design, manufacturing, use and management to cope with the unique physical and chemical properties and potential risks of dangerous goods.   For example, containers loaded with explosive and oxidizing dangerous goods must be thoroughly cleaned to ensure that their structure is suitable for shipment. At the Dafeng factory, the container business unit has successfully opened a second production line, focusing on the production of customized special containers.   Our new production line uses advanced production equipment and processes to efficiently and quickly produce various types of special containers, including side-opening containers, electrical equipment boxes, logistics containers, etc. This allows us to greatly shorten the production cycle while ensuring product quality, and meet the urgency of customers' customized needs. In addition, our special container design team has rich experience and expertise and can provide personalized solutions based on customers' specific needs. Whether it is an oversized and over-wide container for transporting large goods, or an explosion-proof container for special environments, we can provide professional and reliable customization services.   For hazardous chemicals with higher storage and transportation requirements among hazardous goods, they should be zoned, classified, and stored in separate warehouses according to their performance. All types of hazardous chemicals must not be mixed with prohibited materials. The storage of hazardous chemicals at the accident site is chaotic, and in the later rescue process, there are hazardous goods that cannot be extinguished with water. Using a large amount of water to extinguish the fire will cause more explosion accidents. Different types of hazardous chemicals require different storage conditions, such as temperature control, ventilation system, etc. Outdoor hazardous chemical temporary storage cabinets can be equipped with temperature control systems, combustible gas detection, sound and light alarms, automatic fire extinguishing systems, etc. according to actual needs to meet the storage requirements of different hazardous chemicals!  

OSHA is the abbreviation of Occupational Health and Safety Administration, which usually refers to OSHA 29 CFR1910, which is OSHA's occupational safety and health regulations. Codes and standards for safe product storage include: Specification for Flammable and Combustible Liquids 1910.106; Supplementary Requirements for Flammable Liquids and Liquids with Flash Points Above 199.4°F (93°C) for Dipping and Spraying Operations 1910.125; for marking physical hazards characteristic. Combustible liquid: Combustible liquids are chemical liquids classified as Class II and III [with a flash point of 100 degrees Fahrenheit (37.8°C), as shown in the diagram on this page. Flammable liquid： Flammable liquids refer to Class I chemical liquids (flash point

SPCC is Spill Prevention, Control and Countermeasures. What are SPCC regulations? What are the objects of its regulations? SPCC is the abbreviation of Spill Prevention, Control and Solutions. This regulation is intended to prevent oil contamination of U.S. waterways under the authoritative rules of the Federal Water Pollution Control Act and the Clean Water Act. The SPCC Code outlines the requirements for owners and operators of onshore and offshore facilities to prepare and implement leak prevention, control and resolution plans. Application of leak prevention and control products SPCC regulations require production owners and operators to implement SPCC plans as a secondary leak prevention and control solution for containers larger than 55 gallons. Each secondary leakage prevention and control product must comply with: (1) Can accommodate the entire volume of liquid in the largest container. (2) Have enough ultra-high sediment. Remark: (1) Super height: the vertical distance from the lowest point where the contained liquid spills. (2) The super height of the leakage prevention and control pallet must be determined by the production owner or operator, or his engineer, and stated in the SPCC plan. (3) Good Engineering Practice states that pallets with protective structures do not need to be extra high to contain sediment.

The certifications and standards that safety cabinets need to comply with include the following: 1:CE 2: OSHA 3：EN 14470-1 CE is a safety certification , which is regarded as a passport for manufacturers to open and enter the European market. CE stands for European Unity (CONFORMITE EUROPEENNE). The CE mark on the product indicates that it complies with the basic requirements of the EU new approach directives and does not need to comply with the requirements of each country, thus realizing the free circulation of goods within the EU member states. The basic requirements in the directive refer to: public safety, health, environmental protection and protection of consumers. Among the products currently circulating in the EU unified market, more than 70% of the products have been included in the list of products that must be affixed with the CE mark, otherwise they are not allowed to enter the market. CE mark certification is a certification for specific products, focusing on the safety characteristics of the product. It is a compliance certification that reflects the product's requirements for public safety, health, environment and personal safety.   EN 14470-1 was established in Europe in April 2004. It is a safety standard for storing chemicals, mainly requiring detailed production of safety cabinets. Most people in China know about FM safety certification, but few know about the EN 14470-1 standard. In fact, the EN 14470-1 standard is much higher than the FM standard. The EN 14470-1 standard includes three main basic safety requirements: reducing fires caused by chemicals stored in safety cabinets, and improving the protection of these materials in the event of a fire. The latter also sets a fire resistance time (FR, unit: minutes). Reduce the emission of chemical gases into the environment. Keep the leakage of chemical gases in the cabinet. EN14470-1 includes 4 fire resistance categories. The fire resistance time of safety cabinets is divided into four levels: 15 minutes, 30 minutes, 60 minutes, and 90 minutes to meet the different needs of EU member states.   OSHA standards, namely occupational safety and health standards, currently have no unified international norms in this field. With the continuous progress of society, people are paying more and more attention to their own safety and health issues, especially occupational safety and health, which has prompted countries to compete to establish occupational safety and health standards suitable for their national conditions. The most representative of these is the OSHA standard issued by the Occupational Safety and Health Administration of the United States. The US OSHA standard is an occupational safety and health standard implemented within the scope of the US judicial power management. Its rich safety and health cultural content, rigorous safety management philosophy and scientific and economical safety management methods have not only been highly recognized by various industries in the US society, but also widely respected by the world, especially in the field of international engineering construction.

CE certification is the EU's product certification. It is the basic safety requirement that products do not endanger the safety of humans, animals and goods, rather than general quality requirements. The coordination directive only stipulates the main requirements, and the general directive requirements are standard tasks. The CE mark is a safety conformity mark rather than a quality conformity mark. It is the "main requirement" that forms the core of the European directive. What is EN certification? EN is a regulation and EN is a standard. Only after passing the EN test can the CE mark be affixed and you can leave the EU. What EN is opened is the product standard. Different products correspond to different EN standards. If a product passes the test of a certain EN standard, it also means that it meets the requirements of CE certification, so it is sometimes called EN certification.   What is the relationship and difference between ce certification and en certification? EN (European Standard): According to the common obligations undertaken by participating countries, the adoption of this EN standard will give legal status to the relevant national standards of a member state, or cancel the relevant standards of an opposing country. In other words, the national standards of member states must be consistent with EN standards. Only products that pass EN's testing standards can obtain CE certification. The difference between en certification and ce certification In simpler language, what is the relationship and difference between ce certification and en certification? CE is a regulation and EN is a standard. Only after passing the EN test can the CE mark be affixed.

Extreme weather such as high temperature and lightning in summer will affect the safety of personnel, equipment and chemicals, and improper response will easily lead to accidents. How to ensure the safe storage of dangerous chemicals in summer, come to understand it. The expansion coefficient of flammable liquid is generally large, stored in a closed container, the volume expands after being heated, and the vapor pressure increases, so that the internal pressure of the container increases, if it exceeds the pressure that the container can withstand, it will cause the container failure or even rupture. The phenomenon of "drum" in the iron drums containing flammable liquids in the high temperature season and the explosion of glass containers are all due to the thermal expansion of the stored liquids. If the container is open, the liquid expands beyond its capacity and spills over. Affected by environmental factors such as temperature and humidity, many dangerous chemicals are easy to decompose after being heated, releasing oxygen or even oxygen atoms, oxidizing other substances, and releasing a large amount of heat. If the ventilation is poor, the heat accumulation does not disperse, resulting in a rise in temperature, it will accelerate the oxidation rate, generate more heat, and promote the temperature to continue to rise, when the temperature reaches the spontaneous combustion point of the substance, it will spontaneously ignite.   ZOYET Outdoor chemical storage container help you solve the problem of storing dangerous chemicals at high temperatures.
