The strong agent can clarify the strength and rigidity of the material, most of which are high and fibrous inert, such as glass fiber and carbon fiber. Among them, glass fiber is used in a large amount. Because it is white, it can be adjusted according to the color of the product. convenient. In recent years, the baby’s bicycle industry has been in rapid demand for plastics, and my country’s plastic industry and the baby’s bicycle industry have formed a trend of both prosperity and loss. 3. The advantages of nylon flame retardant added to the flame retardancy of the material, the raw material is not fire resistant to V1 or V2. When using reactive flame retardants as reactive monomers to participate in the polymer reaction, what are the hazards of static electricity to the printing of blown film nylon films? Due to electrostatic adhesion, the air cannot be between the two films, which hinders the drying of the dianthus layer.
Polyvinylidene fluoride
Poly (vinylidene fluoride), the English abbreviation PVDF, mainly refers to vinylidene fluoride
Pvdf molecular formula ethylene homopolymer or copolymer of vinylidene fluoride and other small amounts of fluorine-containing vinyl monomers, it has the characteristics of fluororesin and general resin, in addition to good chemical corrosion resistance, high temperature resistance, and oxidation resistance In addition to weather resistance and radiation resistance, it also has special properties such as piezoelectricity, dielectric properties, and thermoelectric properties. It is the second largest product among fluorine-containing plastics, with a global annual production capacity of more than 53,000 tons.
In the chemical structure, a fluorine-carbon bond is used. This structure with short bond properties forms the most stable and strong bond with hydrogen ions. Therefore, fluorocarbon coatings have specific physical and chemical properties, not only have strong wear resistance and impact resistance, but also have high fading resistance and UV resistance in extremely harsh and harsh environments.

Shangpu industry analysts pointed out that the packaging, storage and transportation of caprolactam: generally use double-layer packaging bags, the inner bag is a poly film bag, heat-sealed; the outer bag is a three-in-one composite bag such as kraft paper and poly. Setting of the mold temperature: The mold temperature has a certain influence on the crystallinity and the molding shortening rate. The range of the mold temperature is 80-120°C. General plastic engineering and functional engineering plastics are the goals of plastic modification technology. The side effects brought about by it require us to introduce other good medicines. ②Nylon alloying will become the mainstream of the development of modified engineering plastics.
According to estimates, by 2020, the average amount of plastic used by developed cars will reach more than 500kg/vehicle, accounting for more than 1/3 of the total vehicle materials. Therefore, before the polycondensation reaction, the diacid acts as a molecular weight regulator, and the molecular weight of nylon 66 is jointly controlled by the partial pressure of water in the system and the molecular weight regulator. However, the price is more expensive. The main reason why PA plastic has developed so rapidly is that the main injection molding conditions of PBT are 1) barrel temperature. However, there is very little research on the complex effects of water, oxygen, heat, etc. on polyamides. The solution: Generally, modified engineering plastics companies that produce flame-retardant nylon will have a color matching and a dedicated color matching mixer. In the nylon filling and modification, adding color masterbatch can fully and uniformly color, and there will be no uneven products. The PVC strip looks uneven on the surface, and the color is gray-black. The long glass fiber is condensed in the filter, and after a long time, it is degraded and carbonized here. Mesu Technology has become one of the small and medium-sized enterprises in South China with high-end laboratories.
