Conventional food emulsifier is the need to use external stirring effect to play a role, and nano degreasing food emulsifier does not need to use external stirring, can play an emulsification role, in layman’s terms: if you take oil and water and conventional food emulsifier three placed together, not by stirring, then oil and water and conventional food emulsifier is not interfering with each other, still oil and water and conventional food emulsifier. If you take oil and water and nano degreasing food emulsifier three together, not by stirring, then oil and water and conventional food emulsifier in 5 minutes after the reaction began to form a non-water non-oil emulsion.
The basic principle of curing reaction of anhydride curing epoxy powder coating is: the hydroxyl group of epoxy resin reacts with the anhydride to generate ester group and carboxyl group; the generated carboxyl group then reacts with the ring The generated carboxyl group then reacts with the ring oxygen group to generate ester group and hydroxyl group; the hydroxyl group reacts with the anhydride group. In this way, the epoxy group reacts with the carboxyl group, the carboxyl group reacts with the hydroxyl group and the chain of pe wax data sheet self-polymerization of the epoxy group, thus forming the trapezoidal structure of the coating film.
Foreign companies with epoxy powder coatings with anhydride curing Zilly’s commodity grades, characteristics and coating film performance is shown in Table 4-36.
Phenol hydroxyl resin
Phenol hydroxyl resin is an important curing agent commonly used in epoxy powder coatings, mainly for heavy corrosion prevention and electrical insulation. This curing agent is a low molecular weight epoxy resin and bisphenol A in the base catalyst, after the addition reaction to get the phenol hydroxyl end group of the product.
