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.

The new regulation mainly divides the scrapping regulations of motor vehicles through the two aspects of operating vehicles and non-operating vehicles. There are limits on the number of years for operating vehicles, from small and miniature taxis to medium-sized passenger cars, and from 8 to 15 years.
Non-operating vehicles, that is, private cars, except for large and medium-sized non-operating passenger cars have a 20-year limit on the number of years of retirement, and other models basically have no age limit. The specific performance is that small, micro-non-operating vehicles, large-scale non-operating cars, and wheel-type special vehicles have no limit on the number of years of use, but there are mandatory scrapping regulations that do not exceed 600,000 kilometers.
In addition to the compulsory retirement conditions for mileage and age, if the vehicle fails to obtain the vehicle inspection mark within three consecutive motor vehicle safety technical inspection periods after the expiry date of the inspection, it will also be subject to mandatory scrap. The deadline for comments on the new draft of the consultation paper is the end of this month. According to sources, this new rule is expected to be formally introduced this year.
Private vehicle scrap new regulations request mileage not exceeding 600,000 kilometers
In response to the problem of scrapping motor vehicles, the "Regulations on Mandatory Motor Vehicle Discarding (Draft for Soliciting Opinions)" (hereinafter referred to as the "new regulations") that the Ministry of Commerce has brewed for a long time has begun to solicit opinions. The new regulations show that the retirement of private cars is not limited by the age limit, but the mileage cannot exceed 600,000 kilometers.
