　　New technology of glass fiber at present glass fiber products abroad basic can be divided into four categories, namely the reinforced thermosetting plastic with glass fiber reinforced material, with glass fiber reinforced thermoplastics, electrical insulation and other purposes of textile fiber glass products and roofing waterproof material with glass fiber. Glass fiber reinforced materials account for about 70%~ 75%, and fiberglass textile materials account for 25%~ 30%. The variety of foreign glass fiber has grown to more than 3000, with more than 50000 specifications. In recent years, the average annual growth of more than 1000 specifications. Foreign experts believe that such a variety of development speed cannot meet the market needs to the maximum extent, only the development of "starting point". The new glass components used to produce glass fiber should be said to date that glass fiber is still mainly used in non-alkali glass, namely E glass. The alkali glass (C glass) containing boron contains only a small amount of the alkali glass fiber products used in the production of acid. Because traditional E glass some weakness in performance and composition (such as chemical corrosion resistance is poorer, glass in the ingredients cause environmental pollution, etc.), almost 10 years there have been some new glass composition and has been put into production. ECR glass is actually modified E glass. It contains no trioxide B2O3, which has strong acid resistance, water resistance, corrosion resistance and short - term alkali resistance. The ECR glass fiber has been widely used in the production of glass tubes and cans for corrosion resistance and corrosion resistance. The non-fluorine E glass is a formula developed in recent years due to environmental pressures, and the cost of glass is increased by replacing fluoride with other fluxes. Ultra high strength glass fiber is a new product recently developed. Its high product name is ZenTron. Its tensile strength is 15% higher than E glass fiber, and its cost is 20% lower than that of s-2 high-strength fiber. It is expected to be widely used in high-performance composite materials. Advantex is a newly developed boron-free glass fiber, whose electrical properties and strength are similar to the standard E glass fiber, and its chemical resistance is similar to that of e-cr glass. Since it does not contain boron, the volatilization of boron compounds in glass melt is avoided, thus reducing environmental pollution and reducing the erosion of refractory materials. Owens-corning has converted 10% of its E glass fiber production to this new component, and is poised to expand its proportion. At present, more than 95 percent of the world's glass fiber is equipped with advanced bath wire. Only some special glass fiber varieties still use the ball. To large-scale development of tank furnace The pool kiln gauge touch under 30 tons/day glass kiln is considered small pool kiln, 30 ~ l00 tons/day for medium and large glass tank furnace, more than 100 tons of glass/day pool kiln kiln for oversize. A large pool of 100 tons of glass can be fitted with large leaky panels of more than 100 pieces. Tank furnace leakage board to develop in the direction of porous, multielement, double bottom, according to the data reported abroad, industrial developed countries pool kiln adopts porous plate leakage, leakage hole plate number is 800, 1600, 2000, 1600, has grown to 6000 and 8000 hole in recent years.
