China Plastics Network teaches you how to buy high quality pp plastic pipe
I believe that many people have bought pp plastic pipes, so how do you buy high-quality pp plastic pipes? Today, the editor of Jiuzhi.com tells how to choose high quality pp plastic pipe:
First, "touch" texture. In general, coarse particles are likely to incorporate impurities.
Second, "look" the color. PP-R pipes are mainly white, gray and green. Consumers often think that white is the best. In fact, color is not a criterion for judging quality.
Third, "smelling" the smell. The main material of the PP-R pipe is polypropylene. The good pipe has no odor, and the poor one has a strange smell. It is likely to be blended with polyethylene instead of polypropylene.
Fourth, "pinch" hardness. The PP-R tube has a considerable hardness, and it is possible to pinch the deformed tube, which is certainly not a PP-R tube.
Five, "ç ¸" flexibility. A good PP-R tube, "rebound" is good, easy to smash naturally is not a good PP-R tube. However, the hardness is not equal to the elasticity. Some manufacturers increase the hardness by adding too much impurities such as calcium carbonate, so they are not broken, and they are easy to be brittle after a long time.
Sixth, "burn" smoke smell. The PP-R tube, which is mixed with recycled plastic and other impurities, emits black smoke and has a pungent odor. After burning a good material, not only will it not emit black smoke or odor, but after burning, the molten liquid will still be very clean.
The above six methods can help you buy high-quality pp plastic pipes. I hope that everyone will be helpful when purchasing pp plastic pipes in the future. More knowledge about plastics will be told later, I hope everyone will pay more attention to Jiuzhi Plastics.

These beads are coated with a special coating materials, during the manufacture of the glass beads, which will improve the characteristics of moisture-proof and adhesion of glass bead. In the way, the life cycle of the glass beads can be prolonged and this enhances the beads reflectivity in a rainy night. These beads are usually used in white or yellow line-construction of highway.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.
