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
As the LED lighting market continues to mature, many manufacturers of traditional fluorescent tubes have gradually transformed and started to produce LED lighting, all expecting to get a share in this emerging market. Since many people do not understand why the internal structure of LED lamps, and even more confused about why LEDs can quickly replace traditional lighting lamps, this time to unde
Talking about the six major problems that often occur in lamps 1. What is the cause of fogging of the lamp tube? If there is mist in the tube: (1) The problem of quartz pipe, that is, dehydroxylation is not good. (2) Or the exhaust is not good during the production process. (3) Then the purity of the gas is insufficient.
