LeXin products stable quality, complete specifications. Flat plastic processing products is various, but the basic include the following contents: mechanical processing products, Polished plastic, sand blasting or frosted plastic, plastic spraying decoration, sculpture, plastic) , heat treatment products ( Toughened plastics, half bending toughened plastics, plastic, glazed plastic, painted plastic) , chemical products ( The chemical toughened plastics, wool surface etching, meng sand plastics, smooth surface etching) Coated plastic ( Endothermic plastic, heat reflection of plastics, low radiation, rainbow plastics, frost prevention plastic, uv, electromagnetic shielding plastics, hydrophobic plastics, plastic, aluminum mirror, silver mirror) The cavity plastic ( Ordinary hollow plastic. Vacuum plastic, inflatable hollow plastic) , laminated plastic ( PV membrane laminated plastic, EN laminated plastic film laminated plastic, decorations, plastics, anti-theft plastic, fire prevention, etc. ) , the paster plastics ( Plastic, laser plastics, sunshade adiabatic plastic, decals) , coloring plastics ( Radiation coloring plastics, diffusion coloring plastics) Special technology processing, plastics ( Laser engraving of plastics, electron beam machining, photochromic plastic, electrically induced discoloration of plastics, sterilizing, since the clean plastic, mouldproof deodorant plastic) 。 Laminated plastics. Quartz plate is made of silicon dioxide special plastic industrial technology, is a very good base material. Quartz has a series of excellent physical and chemical properties, such as, high temperature resistant. Quartz plastic softening point temperature of about ℃, it can be used for a long time under ℃, high temperature short time can reach ℃. Plastic, corrosion resistance, quartz and other little acids material produces chemical reaction, The Times of acid-resistant ability is ceramics, The Times of stainless steel, chemical stability, especially in high temperature is unmatched by any other engineering materials. And good thermal stability. Adapt to the plastic small thermal expansion coefficient, can withstand the severe temperature changes, quartz plastic heating to ℃ or so, will not burst into cold water. , pervious to light performance is good. Quartz plate in the ultraviolet (uv) to the entire spectrum of infrared wave band for good pervious to light performance, visible light transmittance in % above, especially in the ultraviolet spectral region, large transmittance can reach above. Coating is plastic in the plastic one or two on the surface, using the method of physical or chemical plating metal, metal oxide film and made of plastic processing products. Different membrane layer of color and light reflectivity is different, with coating plastic decorative building radiant glory. Plastic can control the incidence of sunshine, of hot reflex plated film to reduce air conditioning energy consumption, and low radiation coating plastic limit indoor heat dissipating outward radiation, a significant energy saving effect in cold region. Spectrum through performance: using the method of spectral absorption hydroxyl calculation formula of the AGE of the company's: = C/T * LOG ( 助教/结核) mm - The hydroxyl content (C C, ppm) The thickness of the T ( mm） Ta na m wavelength of transmittance Tb: sodium m wavelength of transmittance B: China's standard calculation formula: C =. /d*LG（ Ia/I） mm - The hydroxyl content (C ppm) Mickey d thickness Ia sodium line to zero distance, mm） I: sodium absorption peak to zero distance ( mm） Thickness of the spectral transmittance: mm) Other thickness spectral transmittance can use formula: T = ( - R) e- AtT transmittance R: SLR radiation loss. E: the base of natural logarithms. T: thickness ( cm） Spectral transmittance wavelength nm about ℃ high temperature resistant quartz plastic softening point temperature, can be used for a long time under ℃, high temperature short time can reach ℃,
