Professional rubber and plastic board manufacturers rubber and plastic insulation board why there will be flexibility

As a professional rubber and plastic board manufacturer rubber and plastic insulation board, why there is flexibility, the Meikes manufacturers to give you a introduction.

In the production of rubber and plastic insulation board, less steam is needed, and the foaming speed is fast. The steam pressure and heating time must be properly controlled. Otherwise, the foaming particles will be collected due to overheating and the ratio will be reduced. The magnification should also be avoided. Magnification, so as to avoid shrinkage of the molded product, deformation and ripening

Due to the volatilization of the foaming agent in the rubber-plastic insulation board during foaming, the foamed particles are in a vacuum state. Therefore, the foamed particles must be placed in the silo for more than 8 hours to allow the air to fully enter the foamed particles and make the hair The internal and external pressure Balance of the bubble particles. The foamed granules after aging are large in elasticity, dry and loose, and have good fluidity and are easy to form.

At normal temperature, the natural rubber exhibits high elasticity, that is, the natural rubber elasticity is as low as 2-4, the shape variable can reach more than 1000%, and the rebound rate in the temperature range of 0-100 °C can reach 50%-85% or more.

Originally, since natural rubber is a polymer containing an isolated double bond in the main chain of the macromolecule, although the double bond itself cannot be rotated internally, the α single bond next to the double bond is more easily rotated inside, so the Tg is relatively low, being -73 °C.

These machines make rubber and plastic panels an ideal insulation material to prevent them from being eroded by atmospheric media or industrial environments.

People know that rubber and plastic insulation boards have high elasticity, but this is why, but few people know that as a professional rubber and plastic board manufacturer, Meeks will give you an introduction.

The rubber-plastic panel is a natural rubber as a raw material, and more than 98% of natural rubber is a linear polymer compound composed of cis-1,4-polyisoprene. Therefore, the natural rubber is usually in a high-elastic state, and the moving ability of the segment is very large, and the conformational change is easily performed. Under the action of a small external force, the molecular chain has a curl and stretches, the external force is removed, and the macromolecule changes from a stretch to a curl. .
