How much is Wuxi ion exchange resin per ton

Suspension polymerization refers to the polymerization process in which monomer is dispersed into droplets under the action of mechanical agitation or vibration and dispersant, and is usually suspended in water, so it is also called bead polymerization. The characteristics are: there is a lot of water in the reactor, the material viscosity is low, and it is easy to heat transfer and control; After polymerization, only simple separation, washing, drying and other processes are needed to obtain resin products, which can be directly used for molding; The product is pure and even. The disadvantage is that the production capacity and product purity of the reactor are not as good as those of the bulk polymerization method, and the continuous method cannot be used for production. Suspension polymerization is widely used in industry. 75 PVC resin is produced by suspension polymerization, and polystyrene is also mainly produced by suspension polymerization. The reactor is also becoming larger and larger.

Two or more monomers can be used to prepare synthetic resins. This is called copolymerization. For example, the ABS resin widely used in automobile interior is acrylonitrile butadiene styrene resin with high strength and impact resistance. The strength and impact resistance are achieved by combining the properties of hard but impact prone acrylonitrile resin and styrene resin with the properties of soft but impact resistant butadiene resin.

According to the arrangement of monomers, copolymerization can be divided into random copolymerization, block copolymerization and graft copolymerization. In random copolymerization, the monomers are randomly bonded. In block copolymerization, polymers of a certain length made from a single monomer are vertically connected. Graft copolymerization is similar to casting rope. Different types of polymers hang around long polymers made from a single monomer.
