Improve the packaging quality of chemical dangerous goods

At present, China's chemical dangerous goods packaging quality is still very low, and the damage of packaging is still very serious. The direct loss of dangerous goods such as explosions, fires, poisons, and corrosion caused by damaged packaging amounts to millions of dollars each year due to packaging containers. The amount of claims caused by the phenomena of leakage, contamination, etc. caused by the goods far exceeds the amount of the dangerous goods themselves.
We should see that the quality of packaging is low, which is extremely unfavorable to production, to personal safety, and to the development of foreign trade. At the same time, it should be noted that in the future, with the development of industrial and agricultural production and the development of scientific research, the types and scope of use of dangerous chemicals in chemical products will also be expanded, and the tasks of storing and transporting dangerous chemicals in the chemical industry will continue to expand. Regardless of the current or long-term interests, improving the packaging quality of chemical dangerous goods is a problem that needs to be solved urgently.
For a long period of time, our country has implemented a planned economic system. Commodity packaging has been neglected. Many business leaders lack understanding of the importance of commodity packaging and are accustomed to bad packaging practices. In the past few years, there have been a number of consecutive incidents of exporting calcium carbide in the foreign trade department. Due to poor packaging, an explosion occurred when re-exporting in Hong Kong is an example. Therefore, it is very important to improve the packaging quality of chemical dangerous goods. First of all, it is necessary to raise the awareness of the quality of enterprises, so that they realize that the poor quality of packaging will cause undue losses to the country. At the same time, if the market competition is fierce, it will also affect the products. The sales and detrimental to the company's reputation.
At present, the quality of chemical dangerous goods packaging materials is poor and cannot meet the requirements. In particular, the problem of firmness of wooden boxes and cartons stands out. Some wooden boxes are made of decayed wood, not only not strong enough, but even basic strength requirements are not reached. Corrugated cartons are badly damaged due to poor material, strength and moisture resistance. Therefore, to improve the packaging to start with materials, packaging materials should be strictly controlled, use qualified materials.
The other aspect of the correct use of materials is to focus on adapting the characteristics of the goods to the characteristics of the packaging materials, and to select appropriate packaging materials for the chemical hazardous materials that are flammable, explosive, toxic, and corrosive. An accident occurred.
Whether the packaging design and manufacturing process is reasonable or not is as big as the material selection. Although the wooden box is of a good material, it was damaged due to design errors. If there is no baffle outside the box side panel, the stacking or damage of the box occurs during the stacking of the goods, and some cartons do not consider the cooperation with the packaging. The contents of the box are easily collided and broken after being packed. In addition, the manufacturing process does not meet the requirements but also easily cause damage to the packaging, which is particularly prominent in the manufacture of metal containers. At present, there are major defects in the manufacturing process of metal barrels, such as lax welding and sealing, and the quality of the inner coating.
Whether or not the packaging method is reasonable is also an important aspect of whether the packaging can function properly. If the packaging material is very good, but the filling method does not meet the requirements, when the inflated more when the seal is easily broken due to extrusion. In addition, overfilling the contents is also one of the main causes of damage. Therefore, the packaging method should also be taken seriously.
China's chemical dangerous goods packaging should also develop toward the direction of containerization. Chemical dangerous goods have the characteristics of being flammable, explosive, toxic, and corrosive. They are easy to pollute the environment and pose a threat to human health. They use collective packaging to implement centralized transport and mechanization operations, which can help reduce personal injury and environmental protection caused by dangerous goods. To protect freight security.
In addition, the use of packaged packaging can effectively protect the goods and can make up for the lack of packaging itself. Packing and packaging are matched with advanced mechanized operations. In particular, the door-to-door transport method is one of the effective measures for comprehensively treating damaged packaging.
The use of collective packaging can save packaging costs, reduce packaging costs, and promote the standardization, standardization, and serialization of dangerous goods packaging.
At present, the developed countries and regions in the world adopt a high proportion of collective packaging and transportation. In order to adapt to the general trend of development and to conform with international practices, we should also create conditions for the development of dangerous goods containerized transportation.
