Vitamin K, naphthoquinones, fat-soluble. Discovered by Henrik Dam in 1929. It is a collective name for a series of naphthoquinone derivatives, mainly natural vitamin K1 from plants, vitamin K2 from animals, and synthetic vitamin K3 and vitamin K4. Also known as coagulation vitamins. It is mostly found in spinach, alfalfa, cabbage. Soluble PVA is soluble in water, the higher the water temperature, the greater the solubility, but it is almost insoluble. The solubility of PVA varies with the degree of alcoholysis and degree of polymerization. PVA with partial alcoholysis and low polymerization degree dissolves extremely fast, while PVA with complete alcoholysis and high polymerization degree dissolves slowly. As a general rule, the degree of alcoholysis is greater than the degree of polymerization for the influence on the solubility of PVA. The dissolution of PVA is carried out in stages, namely: affinity-swelling-infinite swelling-dissolution.

The overall level of the environmental protection industry is relatively low. By 2004, there were more than 10,000 environmental protection companies in my country, but only 2.8% of large-scale environmental protection companies (of which about 65% were part-timers), and about 90% were small and medium-sized enterprises. With strong R&D institutions, most companies do not have R&D capabilities, or have obvious R&D capabilities. Anti-mold agent, also known as microbial agent, is a kind of chemical auxiliary agent that prevents the polymer resin from being corroded and degraded by microorganisms. Most polymer materials are not resistant to mold, but their products are susceptible to mold due to the addition of plasticizers, agents, fatty acid soaps, etc., which can breed molds during processing. Antifungal agents for plastics contain many chemistry. The more common varieties include organic metal compounds such as organic, organic tin, organic copper, organic arsenic, etc., nitrogen-containing organic compounds, sulfur-containing organic compounds, halogen-containing organic compounds, and phenol derivatives. Things and so on.
The company recycles thousands of chemical products. Our company promises to recycle them quickly, at a reasonable price, and with professional, safe and environmentally friendly methods. Welcome your calls and sincerely look forward to cooperating with you!
