The difference between PE pipe, PVC pipe, PP pipe and PB pipe PVC pipe: tensile, good compressive strength; excellent corrosion resistance; with adhesive, flange, socket installation; light weight, suitable for high-rise buildings. The price is lower than other plastic tubes. The disadvantage is that the flexibility is relatively poor, the low temperature brittleness is poor, and it cannot be use
How to choose the light diffusing agent for PC and PMMA LED tubes? At present, energy-saving and environmentally friendly lamps are becoming more and more popular, and more and more people are paying attention to the development of LED lampshade materials. These lampshade materials are PC (polycarbonate), PMMA (acrylic), etc. What additives can be used to achieve that LED lights are not dazzlin
What are the performance advantages of using PMMA / PC materials in LED lampshades? LED tube shell, PMMA / PC material used in pc lampshade, chemical name Poly polymethyl methacrylate, polymerized by MMA monomer. Referred to as PMMA, commonly known as acrylic, acrylic. The LED lampshade is a thermoplastic with a density of 1.19-1.20, a very high transparency, a transmittance of up to 91% -93%, v
[Introduction] Because of its unique advantages, LED has developed rapidly since its birth. However, in the field of ultra-thin and light-weight LEDs, the thickness of products has fallen below 0.7 mm. PCs have shortcomings such as low strength and linear expansion coefficient. Products are prone to soft deformation and bending problems. In order to solve the problems in this aspect of PC, nano-
【Introduction】 Broken cocoon into a butterfly, with the most gorgeous transformation and a stronger arm. This is very necessary for the development of any brand, an enterprise or even the entire industry. No matter how glorious it was, or faced with embarrassment, when the strength and experience have accumulated in the years, the Phoenix Nirvana is another successful occasion. 2014 is a year of
According to the improvement of international market requirements, in the future, DVD discs in the optical disc industry and the automotive industry will become a potential application market for polycarbonate. When PC / ABS for automotive bumpers and other components have been used in the past 3 years The average annual growth rate of the market for blends has been around 10%, but in view of th
pc tube overall learninig The PC tube is a polycarbonate tube. Polycarbonate (referred to as PC) is a polymer containing a carbonate group in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic Kinds of types. Among them, the mechanical properties of aliphatic and aliphatic-aromatic polycarbonates are low, which limits
The reasons for the cracking of the PC lamp cover can be roughly divided into two types. One is that the material is out of order, the other is artificial, and the material is out of order. Then the solution is also very simple to change the material. What is the artificial situation? What? In general, this is caused by improper installation and operation, and is subject to relatively large pressu
