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.
What are the types of light transmittance of PC covers for LED tubes? The luminous flux of the LED lamp tube has a great relationship with the PC used in the LED lamp tube. The transmittance of each PC transparent cover is different, so even if it is the same power, the same lamp beads, the same The LED lamps are equipped with PC covers with different light transmittances, and the brightness is
What is the reason for the crack of the LED lamp pc cover The reason for the cracking of the pc cover is that the molecular chain structure of the PC is damaged and the molecular chain is broken, resulting in cracks on the surface. There are several factors that affect the molecular chain structure: Use repeatedly. When used repeatedly, the molecules of the product will fission under the actio
Introduction: LED designers have achieved many advantages by choosing PC (not glass and PMMA), including stronger impact resistance and heat resistance, improved flammability levels and increased design flexibility. With the increasing adoption rate of LED lighting, lighting manufacturers are pursuing materials other than traditional materials for lighting applications to promote innovative d
