LED fluorescent lamp PC lampshade LED fluorescent lamp PC lampshade is a kind of LED fluorescent lamp accessories. It is to better gather the light and make the light more concentrated. Heat resistance and cold resistance; also has the advantages of self-extinguishing, flame retardant, non-toxic, colorable and so on. Chinese name LED fluorescent lamp PC lampshade is used for LED fluorescent lamp
Difference: The former uses modified polypropylene as the main raw material, which is easy to use, reduces damage to the road surface, and has a wide range of applications. It has good insulation performance, high temperature resistance, strong compression resistance, light weight, convenient construction, smooth inner and outer walls, low friction, long service life and good performance.

CPVC pipe extrusion process Chlorinated polyvinyl chloride resin (hereinafter referred to as CPVC) was successfully developed by BF Goodrich in 1958. It is a chlorinated product of polyvinyl chloride resin (PVC). The chlorine content of chlorinated PVC can be 57% to 64% to 75%, with the increase of chlorine content, the corresponding temperature resistance, rigidity, chemical resistance, flame
The difference between PVC-C fire special pipe and CPVC civil water supply pipe PVC-C special fire-fighting pipe is the term used in the new national spray regulations, that is, chlorinated polyvinyl chloride pipe, which is specifically for fire-fighting special plastic pipe. GB 50084-2017 "Specifications for the design of automatic sprinkler systems" and GB 50261-2017 "Specifications for the
How is UPVC pipe developed? UPVC pipe application field UPVC pipes and PE pipes are thermoplastic pipes. They have a common characteristic, and they are still recognized by most people in terms of application. What is the development of UPVC pipes? What are the applicable fields of UPVC pipes? Let's explain it to everyone, let's take a look. How is UPVC pipe developed? In August
Rigid PVC basic knowlege Rigid polyvinyl chloride, UPVC is also called rigid PVC. It is an amorphous thermoplastic resin made by polymerization of vinyl chloride monomer plus certain additives (such as stabilizer, lubricant, filler, etc.). But strictly speaking UPVC is hard PVC, but hard PVC is not UPVC. UPVC should be rigorous and scientifically discussed. UPVC should not contain or use plasti
Basic knowledge of UPVC pipe UPVC pipe uses polyvinyl chloride resin as a carrier, which has excellent characteristics such as accurate temperature sensitivity, timed melting, and rapid absorption of active ingredients of additives when weakening the gravitational force between resin molecular chains. At the same time, it uses the world-famous calcium and zinc composite heat stabilizer. In the pr
