Li Faquan, a researcher at the Wuhan Institute of Physics in the Chinese Academy of Sciences, said that the invention of blue LEDs has helped people obtain white light sources in a more energy-efficient way, opening a new era of human lighting. Li Faquan introduced that red LEDs and green LEDs were invented early and were applied to the display light source of machine instruments. However, the blue LEDs with shorter wavelengths have not been settled. The three primary colors of light contain red, green, and blue. Due to the absence of the blue light source, the illuminated white LED light source cannot be created at all. The traditional electronic tube and liquid crystal display use red, green and blue three-primary light sources to synthesize white and other color effects through a certain proportion, and LEDs are also the same. Li Faquan said that whether in the international scientific community or in the corporate world, how to create blue LEDs has plagued people for decades. The award-winning inventions complemented the spectrum with blue LEDs, making white LEDs possible. Li Faquan said that this also means that after the oil lamps, incandescent lamps and fluorescent lamps, human lighting technology has once again ushered in a new breakthrough. LED lights are energy efficient and have a long life. The data shows that LED lamp efficiency is nearly 20 times that of incandescent lamps and nearly 4 times that of fluorescent lamps. At the same time, the service life of the LED lamp can reach 100,000 hours, while the incandescent lamp can only be used for 1000 hours, and the fluorescent lamp can be used for 10,000 hours. It is understood that one quarter of the world's electricity is used for lighting, and LED lights can be used by local low-cost solar energy. This new light source will bring higher quality of life to human beings.
PVC RESIN SG3
There are many grades of PVC. The viscosity or K value commonly used in the industry indicates the average molecular weight (or average degree of polymerization) of PVC, that is, the length of the PVC molecular chain, which determines the grade of the resin and the corresponding processing parameters. The molecular weight of the resin is related to the physical and mechanical properties of the product.
PVC Resin is a kind of non-crystalline linear polymer compound. The larger the relative molecular mass, the higher the viscosity, the higher the molecular weight, and the higher the tensile strength, impact strength, and elastic modulus of the product, but the flow of the resin melt Decline in sex and plasticity. The viscosity number is usually used to indicate the molecular weight of the polymer, and the polymer model is divided
PVC used to be the largest general-purpose plastic in the world, and it is widely used. It is widely used in construction materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc
SG3 (K-70, S1300): mostly used for soft products, hoses, wires and cables, films, shoe materials, toys, auto parts etc.
PVC RESIN SG3 has high purity, less fish eyes, easy to blister, high temperature resistance, insulation, soft product texture, etc. It is mainly used to produce soft products such as wires and cables, agricultural films, conveyor belts, and daily plastic products.
