Discussion on Improving the Packaging Quality of Chemical Dangerous Goods

At present, China's chemical dangerous goods packaging quality is still relatively low, and the damage of the packaging is still very serious. The annual direct damage caused by explosions caused by packaging damage, fire, poison, and corrosion accidents amounts to several million yuan. In recent years, claims for the export of dangerous goods due to cracking, skipping, cracking, etc. of the packaging containers have caused the volume of cargo shortfalls, leakage, and contamination to increase year after year. The amount of such claims far exceeds the loss of dangerous goods.
It should be noted that the low quality of packaging is extremely unfavorable to both the production, the people’s life and the development of foreign trade. At the same time, it should also be noted that with the development of industrial and agricultural production and the level of science and technology. The varieties and scope of use of chemical dangerous goods will also expand, and the tasks for the storage and transportation of dangerous chemicals in the commercial and foreign trade sectors will continue to increase. Therefore, from the perspective of long-term interests, improving the packaging quality of chemical dangerous goods is a problem that needs urgent solution. .
First, the way to improve the packaging quality of dangerous chemicals in chemical industry has caused many reasons for the low quality of chemical dangerous goods packaging. Therefore, the improvement of the packaging quality of chemical dangerous goods should also start from many aspects:
1. It is necessary to vigorously publicize the significance of the packaging of chemical dangerous goods, so that people can raise their awareness from ideology.
For a long time, our country has implemented a planned economy. The packaging of commodities that are part of the market is excluded and neglected. Many business leaders lack understanding of the packaging of goods and are accustomed to bad packaging. This ideological contempt often causes unexpected consequences in practical work. Several consecutive cases of export of calcium carbide explosions in the foreign trade department in previous years are an example. . To improve the quality of chemical dangerous goods packaging, we must first raise the awareness of the quality of corporate personnel, so that they realize that poor quality of packaging will cause undue losses to the country. At the same time, in the fierce market competition, it will also affect the output and loss. Corporate reputation. The accident told us that if we want to change the current state of packaging of dangerous chemicals, we must first solve people's ideological understanding, only the ideological attention will have a technical improvement.
2. Find out the reasons from the packaging technology and make improvements to improve the quality of the packaging.
(1) Packaging materials:
At present, many poor packaging materials can not meet the standard requirements, especially the wooden box, carton material issues are more prominent, and some wooden boxes made of dead wood is not only weak and even the basic strength can not reach, such as a certain number of stations surveyed There are more than 20 boxes in the wooden boxes and 250 metal boxes inside, which are seriously scattered, accounting for 8% of the total. Corrugated cartons are not able to meet the requirements due to poor paper strength and moisture resistance. Therefore, it was severely damaged in the humid south. Therefore, to improve the quality of packaging, we must start from the material and strictly control the use of qualified materials for packaging. At present, chemical dangerous goods packaging materials include metal barrels, plastic barrels, sacks, plastic woven bags, etc., among which metal barrels have iron barrels, tinplate barrels, iron plastic barrels, and other packaging properties are different, and the packaging of goods is also quite complex, so It is necessary to select suitable packaging materials for the flammable, explosive, toxic, and corrosive properties of chemical dangerous goods so as to prevent accidents due to inappropriate materials.
(2) Packaging design and manufacturing process.
The suitability of packaging design and manufacturing process is not less than the requirement for packaging materials. Although some of the wooden boxes are of good quality, due to design errors, such as the design of the backboard outside the box side panel, the stacking or damage of the box still occurs during the stacking of the goods; some cartons are not designed with the contents of the box. After packing, the contents were broken due to collision. This is particularly prominent in the manufacture of metal containers. The current problem with the manufacture of metal containers is the lack of strict welding and sealing during the manufacturing process and the quality of the internal coating. At present, under the efforts of various parties, the production of packaging barrels has been replaced by manual welding with manual welding. The advanced technology of circular-arc crimping is increasingly used by packaging manufacturers, and packaging design has also been greatly improved.
(3) Packaging methods.
The packaging material design process meets the requirements and the packaging method must be reasonable in order for the packaging to perform its normal functions. For example, some packaging bags are of good quality, but are damaged due to overpacking of the improperly packed bag after compression and packaging. Overfilling can also cause damage to the package, so the packaging cannot be ignored.
3. Continue to strengthen the inspection of chemical dangerous goods packaging, formulate corresponding standards, and promote the improvement of chemical dangerous goods packaging quality.
Since the start of commodity packaging inspection, the commodity inspection authorities have completed more than 40,000 shipments of dangerous goods packaging inspections, detected 1,400 batches of unqualified batches, and eliminated 1600 hidden accidents in a timely manner.
In order to ensure that all parties in the industry, trade, and inspection have a legal basis, and urge enterprises to consciously improve the quality of packaging, it is necessary to improve the general standards and test standards for dangerous chemicals packaging types in China so that manufacturers can follow them. In addition, various transportation methods (railway, highway, water transportation, and aviation) should put forward more specific requirements for dangerous goods according to the characteristics of the mode of transportation in order to form a mutually compatible series of goods packaging. In addition to formulating standards, we must strengthen legislation and strengthen quality management. Chemicals dangerous goods packaging management work has rules to follow, there are laws to follow.
Third, the development direction of China's chemical dangerous goods packaging China's chemical dangerous goods packaging should develop towards the direction of containerization. Chemical dangerous goods have the characteristics of being flammable, explosive, toxic, corrosive, polluting the environment and threatening human health. The use of collective packaging for containerized transportation and mechanized loading and unloading operations can help reduce the risk of chemical dangerous goods and reduce environmental impact. Pollution, ensure cargo safety.
In addition, packaged packaging can effectively protect the goods but also make up for the lack of packaging itself. The integration of the collective packaging with advanced mechanized operations, especially the implementation of "door-to-door" container transportation, is an effective measure to comprehensively deal with damage to packaging. For example, the paint packaging exported from Shanghai has dropped since the experiment to date, and there have been no bumps in the packaging after the goods arrived at the port of destination. After adopting containerized transportation, the customer reported that all paints were intact and no leakage was observed during discharge.
The use of collective packaging can also save packaging costs, reduce packaging costs, and promote external sales. Standardize, standardize and serialize dangerous goods packaging.
At present, the developed countries and regions in the world have adopted integrated packaging and transportation. In order to adapt to the development trend and international standards, we should vigorously develop collective packaging and transportation.
