In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects
PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.
The production process of PVC Resin SG8 and PVC RESIN SG5 is basically the same, and the production equipment is exactly the same. The main difference lies in the formulation of additives, polymerization temperature, reaction pressure and so on. The reaction temperature and reaction pressure of SG-8 resin have basically reached the working pressure limit of the polymerizer. The reaction requirements are relatively strict, and the requirements on operation, safety, technology, and personnel quality are more stringent, and the resin quality is more difficult to control.

Wang Jian, Director of the Department of Atmospheric and Noise Pollution Control of the Department of Pollution Control of the Ministry of Environmental Protection, said that the in-depth analysis of urban atmospheric environmental quality changes has been affected by factors such as the increase in the number of car ownership and changes in people’s lifestyle. While the total discharge of pollutants remains high, new emissions of pollutants, especially volatile organic compounds (VOCs), are increasing. The atmospheric composition is becoming more and more complex, and the impact on atmospheric quality is increasing. The bigger. At present, China has no effective means of preventing and controlling volatile organic compounds emitted by industrial enterprises.
According to reports, the R&D Center will use the resources advantages of the Chinese Society of Environmental Sciences to actively carry out research, development, testing and related standards for the development of new technologies and products for the protection of the atmosphere; recycling of organic chemicals, petrochemicals, pesticides, and coating, Various organic waste gases produced in the coatings, rubber (recycled rubber), fiber, plastics, printing, ink and other industries, while vigorously promoting the application of new environmental protection technologies, the establishment of demonstration projects.
On May 10th, the first organic waste gas pollution prevention and R&D center in China's environmental protection field, the Beijing Yunchentian Industrial Organic Waste Gas Pollution Prevention and R&D Center of the China Environmental Science Society, was unveiled in Beijing. Experts said that the establishment of the R&D center will play an active role in the promotion of atmospheric protection, environmental governance, and industrial organic waste gas treatment technologies in China and even in the world.
