How to maintain the color stability of resin tile?

Synthetic resin industrial products can be divided into general resin and special resin. The production of general resin is large and the cost is low. The resin tile is generally used for general consumer goods or durable goods. The representative varieties of resin tile are polyethylene, polypropylene, polyvinyl chloride, polystyrene and ABS; Special resin generally refers to the resin produced for special purposes, with small output and high production cost.

Direct production of pipes, plates and other quality products, so it is also called block polymerization. The disadvantage is that the viscosity of the material increases with the polymerization process, mixing and heat transfer are difficult, and the temperature of the reactor is not easy to control. Bulk polymerization is often used in the production of poly (methyl acrylate) (commonly known as plexiglass), polystyrene, low density polyethylene, polypropylene, polyester and polyamide.

It is dispersed in the form of granules and appears as a slurry. It was previously classified as heterogeneous solution polymerization in some literatures. This polymerization is characterized by low viscosity of the system, easy mixing, and easy heat dissipation. Kunming resin tile can use higher monomer concentration to improve unit equipment productivity. At present, this method can be used in the production of high-density polyethylene, polypropylene, etc.
