The purpose of the plastic corrugated pipe and characteristics

Polypropylene plastic corrugated pipe forming machine are made of extrusion, extrusion and compression molding, its forming characteristics as follows:

(1) the plastic corrugated pipe shall strictly control the temperature in the processing, in order to prevent the oxidation.

(2) the raw material of plastic corrugated pipe material must be dry processing and recycling system.

(3) of the plastic corrugated pipe forming the board that can be painted, bonding, welding and machining, can also be compressed into a variety of optical mirror and other shapes.

The primary USES of plastic corrugated pipe is as follows:

Due to the plastic corrugated pipe forming machine has the certain strength, and good transparency, a transparent, so many used for automotive wiring harness, electronic machinery, high temperature resistant, etc. Corrugated pipe is a kind of polypropylene polymers, the molecular weight between 500000-1 million. Bellows of excellent optical performance, light transmittance can reach 92%, colorless, almost no absorption of visible light, good color, almost do not fade, in under the action of heat does not change color; Corrosion resistance, good weather resistance, good electric properties, and corrugated pipe is alkali, acid, inorganic salt and grease, long exposure outside its transparency and color change is very small, when good arc resistance and no leakage, surface resistance. Corrugated pipe is small surface hardness of products, the disadvantages of easy cut, thermal expansion coefficient is big, high water absorption, the size of the large expansion amount caused by temperature and humidity;

Low notched impact strength, easy to produce stress cracking; High electric insulation, easy charged; Products combustible, no flame, non-toxic. Plastic corrugated pipe superior performance, as long as used in electronic appliances, auto parts, mechanical equipment, precision instruments, to generation of metal zinc, copper, iron and other materials. Plastic corrugated pipe forming machine type belongs to the high temperature resistant aromatic heterocyclic polymers, plastic corrugated pipe is made up of binary acid and diamine polycondensation. Plastic corrugated pipe of polyimide molecules containing heteroatoms nitrogen in the main links of the five yuan, plus a lot of aromatic ring rigidity, therefore has many special properties. The density of plastic corrugated pipe is 1.4 ~ 1.43 g/c ㎡, bibulous rate was 0.32%, the working temperature of 300 ℃ continuous heat temperature of 249 ℃, the thermal deformation is 360 ℃, the elongation is 6% - 8%, the tensile and intensity of 74-95 mpa, chemical resistance stability, is a natural resin. Plastic corrugated pipe of polyphenylene oxide (PPO) is a kind of high temperature resistant thermoplastic resin.

Polyphenylene oxide contained in the plastic corrugated pipe is non-toxic, and the density is small. Plastic corrugated pipe of polyphenylene oxide has high mechanical strength, good comprehensive performance, resistance to stress relaxation, elastic fatigue, creep and other prominent role. Plastic corrugated pipe heat, heat and temperature is about 90 ~ 150 ℃, can be in - 190-150 ℃ for long-term use. Plastic corrugated pipe forming can be extrusion, extrusion, plating, machining, welding. Plastic corrugated pipe can be used in electronics, electrical appliances, automobile, machinery, office equipment, household appliances, insulation parts, instruments and meters, etc.
