There are many grades of PVC. The viscosity or K value commonly used in the industry indicates the average molecular weight (or average degree of polymerization) of PVC, that is, the length of the PVC molecular chain, which determines the grade of the resin and the corresponding processing parameters. The molecular weight of the resin is related to the physical and mechanical properties of the product.
PVC used to be the largest general-purpose plastic in the world, and it is widely used. It is widely used in construction materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc
SG3 (K-70, S1300): mostly used for soft products, hoses, wires and cables, films, shoe materials, toys, auto parts etc.
PVC RESIN SG3 has high purity, less fish eyes, easy to blister, high temperature resistance, insulation, soft product texture, etc. It is mainly used to produce soft products such as wires and cables, agricultural films, conveyor belts, and daily plastic products.

The double-head phase friction welding machine is currently produced in only a few developed countries in the world. There are no manufacturers in China, and even users are rare. This type of equipment is mainly used in the production of automotive transmission shafts, which have the advantages of high efficiency, good quality and no pollution. Especially with the development of China's automobile industry, the demand for double-head friction welding machines is growing. Importing a double-head friction welder from abroad requires nearly 10 million yuan, and the friction welder developed by the company is only one-eighth of the price of foreign products, and the quality level is not inferior.
The XK9360 ball channel CNC milling machine is an urgently needed special equipment for machining the universal joint in the automotive industry. The CNC milling machine developed by the company has high precision and high efficiency, good stability, can be milled and milled, and the price is lower than imported products. It is reported that the above two new equipment will be unveiled at the 8th China Machine Tool Trade Fair.
PVC Resin is a kind of non-crystalline linear polymer compound. The larger the relative molecular mass, the higher the viscosity, the higher the molecular weight, and the higher the tensile strength, impact strength, and elastic modulus of the product, but the flow of the resin melt Decline in sex and plasticity. The viscosity number is usually used to indicate the molecular weight of the polymer, and the polymer model is divided
Changchun CNC welding machine, CNC milling machine developed successfully
In just over four months, Changchun CNC Machine Tool Co., Ltd. successfully developed two CX-12 double-head phase friction welders and XK9360 ball-channel CNC milling machines, which are currently unable to produce important equipment in China, thus serving China's equipment manufacturing industry. Independent innovation has contributed.
