Plastic, using monomers as its raw materials, will become macromolecules through polyaddition or condensation reactions, commonly known as plastics or resin, its composition and physical style can be changed freely. It consists of synthetic resin and filler, plasticizers, stabilizers, lubricants, colorants and other additives.
The main ingredient of plastic is resin; the term resin was originally known as lipids secreted by animals and plants, such as rosin, shellac etc., resin is high polymer that have not yet mixed with various additives. Resin takes up 40% to 100% of the total weight of plastics. The basic properties of the plastic is mainly determined by the nature of the resin, the additives also play an important role;
some plastics are basically composed of a synthetic resin, without or containing very small qty of additives, such as plexiglass, polystyrene and the like. The so-called plastic, in fact, is one of the synthetic resins, its shape is similar to the pine resin in the category of natural resin, but it is called plastic due to its artificially synthesized by chemical means. According to different characteristics of usage of different plastic, it’s usually divided into three types, namely common plastics, engineering plastics and special plastics.
SIEHE Industry provides equipment and plant construction for plastics manufacturers. We offer the entire plant output, engineering design service, factory renovation, expansion services, project management consulting services, design services to the difficulties in plastic production thoroughly.
Main Equipment and Function Introduction:
Blender: For batch blending or coloring plastics. Several blenders (vertical type or horizontal type) with full specification from lab one to production one are optional.
Reaction Kettle: Normally it is divided into pressure or pressurized vessel. It consists of kettle body, kettle cover, jacket, agitator, driving device, shaft sealing device, bearing (ground support type or platform lug type) and other parts. Different shaft sealing, cooling/heating method and mixing method can be customized.
High-shear Emulsifier: It is used for homogenizing and emulsifying raw materials. Inline type is widely used in plastic industry.
Packaging Machine: includes valve bag and top open bag packing machine. Based on filling range, it is divided into up to 5kg, up to 50 kg and ton-bag packaging.
Conveyor: Including powder pneumatic conveying (positive pressure, negative pressure, dense phase, dilute phase) and mechanical conveyor (spiral, belts, bucket, etc.); liquid positive pressure and negative pressure conveying, pumping.
