The important role of LED PC lampshade for lighting industry

by:Inlity     2020-05-29

LED green lighting age has come, as a 'world factory' of China, the emerging of LED lighting industry development potential is infinite. Because in the LED industry in China started late, at the same time, on the basis of the LED core technology and patent by foreign monopoly, the development is relatively slow, but as the national and local support in LED industry have gradually increased, China began full into the LED industry development.

as the national key support, foster the development of strategic emerging industries, LED lighting is a new generation of lighting application of revolutionary technology has the characteristics of energy saving, environmental protection, high efficiency, especially in the traditional energy, environmental pollution factors such as restriction, LED lighting industry will undoubtedly become a focus of national key projects and social concern. But, at present the LED industry is in a state of chaos, PC chimney products price and quality difference is very big also, especially last year with a series of LED the collapse of the pearl river delta, including many well-known listed companies, by luck of survival enterprise also began to face the future distress. LED enterprise partial collapse of the more aggravated the fierce competition in the LED lamps and lanterns of accessories industry, because of less cake, each LED accessories enterprises, share more limited, how to win in the competition, make the product quality is the first, followed by price and after-sales service, a leader in these a few respects old customers have been peer poaching, a steady stream of new customers also. Here in this paper, the research and development production of PC product characteristics and application scope of PC lampshade lampshade is a kind of amorphous and odourless, non-toxic, highly transparent colorless or yellowish thermoplastic engineering plastics, has excellent physical and mechanical properties, especially the excellent impact resistance, high tensile strength, bending strength, compression strength; Creep is small, size stability; Has good heat resistance and low temperature resistance, in relatively wide temperature range has the stable mechanical properties, dimensional stability, electrical properties and flame retardancy, can be in - Long-term use under 60 ~ 120 ℃; No obvious melting point, in 220 - 230 ℃ in molten state; Due to the molecular chain rigidity, resin melt viscosity; Bibulous rate is small, small shrinkage rate, high dimensional accuracy, good dimensional stability, membrane permeability is small; Self-extinguishing material; Light is stable, but not resistant to ultraviolet light, good weatherability; They can withstand oil, acid, alkali resistant, oxidizing acid and amine, ketone, soluble in chlorinated hydrocarbons and aromatic solvents, easy cause hydrolysis and cracking in the water for a long time the PC chimney alloy variety, improve the melt viscosity (PC lampshade Processability) And products easy to stress cracking and other defects, PC chimney form alloy with different polymer or blend, improve the material performance. Specific have PC/ABS alloy lampshade, PC chimney/ASA alloy, PC, PC/PBT alloy lampshade lampshade/PET alloy, PC/PET/elastomer blend lampshade, PC, PC/MBS blend lampshade lampshade/PTFE alloy/PA alloy, PC chimney, there are two kinds of material performance advantages, and lower costs, such as PC/ABS alloy in the chimney, PC chimney main contribution to the high heat resistance, good toughness and impact strength, high strength, flame retardancy, ABS can improve the formability and apparent quality, reduce the density. PC three major application fields of the lampshade is glazing, automobile industry and industrial electronics, electrical appliances, and industrial machinery parts, disc, packaging, computer and other office equipment, medical and health care, thin films, leisure and protective equipment, etc.
