Plastic pipe: plastic pipe is a synthetic macromolecular compound {polymer}, also known as macromolecule or macromolecule, also commonly known as plastic pipe or resin, which can freely change the shape and style. It is a material polymerized by monomer raw materials through synthesis or condensation reaction, and is composed of synthetic resin, filler, plasticizer, stabilizer, lubricant, pigment and other additives. The main component of plastic pipe is synthetic resin. The term resin was originally derived from lipids secreted by animals and plants, such as rosin, shellac, etc. At present, resin refers to a polymer that has not been mixed with various additives. Resin accounts for 40%~100% of the total weight of plastic pipe. The basic performance of plastic pipe mainly depends on the nature of resin, but additives also play an important role. Some plastic pipes are basically composed of synthetic resin with no or little additives, such as organic glass, polystyrene, etc. The so-called plastic pipe is actually a kind of synthetic resin. Its shape is similar to the pine resin in natural resin, but it is also synthesized by chemical force, so it is called plastic pipe.

Rubber sand blasting pipe : High elastic polymer compound. It is divided into natural rubber sand blasting pipe and synthetic rubber sand blasting pipe. Natural rubber sand blasting pipe is made of gum extracted from rubber sand blasting pipe tree, rubber sand blasting pipe grass and other plants; Synthetic rubber sand blasting pipe is obtained by polymerization of various monomers. Rubber sand blasting pipe products are widely used in industry or all aspects of life. Rubber sand blasting pipe is divided into natural rubber sand blasting pipe and synthetic rubber sand blasting pipe according to raw materials. It can be divided into block rubber, latex, liquid rubber sand blasting pipe and powder rubber sand blasting pipe according to the shape. Latex is colloidal water dispersion of rubber sand blasting pipe; The liquid rubber sandblasting pipe is an oligomer of the rubber sandblasting pipe, which is generally a viscous liquid before vulcanization; The powder rubber sand blasting pipe is used to process the latex into powder for batching and processing. The thermoplastic rubber sand blasting pipe developed in the 1960s does not need chemical vulcanization, but uses the processing method of thermoplastic pipe to form. Rubber sand blasting pipe can be divided into general type and special type according to use.

Differences between the two:

The most essential difference between plastic pipe and rubber sand blasting pipe is that plastic deformation occurs when plastic pipe is deformed, while rubber sand blasting pipe is elastic deformation. In other words, it is not easy to restore the plastic pipe to its original state after deformation, while the rubber sand blasting pipe is relatively much easier. The elasticity of plastic pipe is very small, usually less than 100%, while the rubber sand blasting pipe can reach 1000% or more. Most of the plastic pipe products are finished in the molding process; The rubber sand blasting pipe needs vulcanization after the molding process is completed.

Both plastic pipe and rubber sand blasting pipe are polymer materials, which are mainly composed of carbon and hydrogen atoms. Others contain a small amount of oxygen, nitrogen, chlorine, silicon, fluorine, sulfur and other atoms, which have special performance and use. At room temperature, the plastic pipe is solid and hard, and cannot be stretched and deformed. The rubber sand blasting pipe has low hardness and elasticity, which can be stretched and lengthened, and can be recovered after stopping stretching. This is due to their different molecular structures. Another difference is that the plastic pipe can be recycled and reused for many times, while the rubber sandblasting pipe cannot be recycled and reused directly, and can only be used after being processed into recycled rubber. The shape of the plastic pipe at more than 100 degrees to 200 degrees is similar to that of the rubber sand blasting pipe at 60 degrees to 100 degrees. The plastic pipe does not include Rubber sand blasting pipe 。
