The switch socket is mainly composed of a switch panel , a switch base box, and some electronic components. The switch panel is directly visible to us. It plays more of a protection and decoration function, so the material selection is also very important. What is the choice? Material switch panel is good? What are the tips for buying a switch panel?
A, switch panel what material is better
1, imported PC material
PC materials, known as polycarbonate, also known as bulletproof rubber, have excellent heat resistance, flame retardancy and high impact resistance, and it has very good resistance to ultraviolet light even after long-term use. Will not change color.
On the market, high-end brands of switch products will choose PC materials as the panel material, and the international big brands will also use the PC material for the rear shell of the product's functional components to improve product safety in a more comprehensive manner. At present, only three foreign companies, GE GE, Teijin and Bayer, supply PCs.
2, domestic PC material
There is no real pc board in China. The so-called domestic PC materials are mostly recycled PC materials and then undergo secondary processing. The performance of this panel is far less than that of all imported PC panels. .
3, nylon 66
Nylon 66 is also used as one of the switch panel materials. Although it is the highest mechanical strength in nylon plastic, it is inferior to PC material in impact resistance and heat resistance, and the material itself has odor, and its hardness and flame retardancy are both comparable. difference.
4, ABS material
The dyeing and flame-retardant properties of ABS materials are very good, and its processing technology is relatively mature, the price is relatively cheap, there are many switch manufacturers to use, but it is poor toughness, weak impact resistance, short service life , And long-term use of the product surface will appear cracks, appear yellowish surface, generally do not recommend the choice.
5, electric jade powder
The switch panel products using jade powder have a rough surface and a slightly grayish color. They were the main materials for switch sockets in China before the 1990s and are almost eliminated now, but some township enterprises are using them.
Second, the switch panel to buy skills
1, identify material
The best material for making a switch panel is PC material. If it is this material, the quality will not be bad.
2, look at the surface
The purchase is to see if the surface is shiny, if there is a glitch product is definitely not good.
3, smell the smell
For odor-free switch panels, the materials used must have chemical composition and be harmful to the body.
4, bending and twisting
When you get the switch panel, you can check the toughness of the product and see if it will crack or deform after bending and twisting.
Editing summary: The above is about the switch panel what the material is better and the switch panel to buy skills, the switch panel material is many, but the quality is good or bad, we must learn to distinguish when choosing, or buy poor The panel will not be used for a long time, and even problems such as electricity safety will occur.
