Why you can buy in the country, Jiangsu Crystal Arts] [fused silica powder "Our customers order products just in Jiangsu Casting fused silica powder products, customers, Jiangsu fused silica powder used in precision casting, the kind of fused silica powder I plant the production level of a product. precision casting molten superfine quartz powder with superior surface area, determine its good filling, followed by ultra-fine fused silica powder has excellent thermal shock resistance, can effectively protect life of the cast product. Further, ultrafine silica powder melting occurs when a certain degree of thermal expansion of the heated, just compensate shrinkage in the curing reaction of the epoxy resin at this temperature, gypsum, so that the casting body is not deformed. casting in order to make gumming short time, often by adding calcium hydroxide or magnesium oxide as a catalyst, is developed on the basis of ordinary sand casting a new process. ceramic shell bushing watering can save a lot of ceramic slurry, applied in production greater. ceramic casting surface roughness up to Ra10 ~ 1.25 microns, dimensional accuracy up to level 3-5, can achieve little without cutting purposes. ceramic casting production cycle is short, metallic high utilization. largest castings of up to ten several tons, mainly used for a variety of large thick-walled precision casting mold casting and casting a single piece of small quantities of dies, forging dies, plastic mold, metal mold, die casting mold, glass molds. ceramic casting mold life with use mold machining methods made comparable, while manufacturing costs are lower than the mold made by machining methods. Lianyungang Crystal Arts Limited production of fused quartz silica powder, fine casting using chemical stability, acid, large specific surface area, a gap developed surface-active, low oil absorption, thickening strong, high temperature, good electrical insulation, anti-UV properties. production and application of the company many years of experience, mature technology and a stable physical and chemical characteristics and reasonable and controllable particle size distribution. has been widely used in rubber, paints and coatings, electronic packaging materials, silicon substrate material features of chemical fiber, functional plastics, advanced ceramics, special refractories, sealants, adhesives and chemicals , medicine, pesticides, etc. The company can produce from 400 to 10,000 head purpose of all products, and related products can be customized according to customer requirements. now I am in the double dawn of fused silica powder is a lot of promotion, the same quality, lowest price, welcome new and old customers advice. corporate hotline [0518-87595696] Enterprise Station http://www.jygwf.com/, first-served basis oh rare opportunity.
