Glass fiber as reinforcement of reinforced plastics or its products, title of glass-fiber-reinforced plastic, or fiberglass. Due to the different types of resins and polyester glass fiber, glass fiber reinforced epoxy, phenolic FRP said. Glass fiber reinforced plastic with a transparent or opaque. Combination of iron and carbon steel, and fiberglass components. Stronger than ordinary glass tempered glass. Advantages are substantial, burst does not produce cutting-edge pieces on the second, more security to people. Fiberglass glass-fiber-reinforced materials, is foreign early 20th century development of a new type of composite material, it has a light weight, high strength, corrosion resistance, insulation, insulation, sound insulation and many other advantages. FRP Windows and doors is the use of medium-alkali glass fiber Rovings and fabrics as a reinforcing material, using unsaturated polyester resin as a matrix material, through a special process using these two materials, and adds other mineral fillers, and then by heat curing, pulling into a variety of different fasting profile machining of sectional form. Specifically FRP door and window’s main features are: anti-aging, strength. FRP profiles without plates as liners in abdominal cavity on an empty stomach, you do not need any single material auxiliary surface, entirely relying on its own structural support. Due to glass fiber and fabric as a reinforcing material, resin-bonded, no filament exposed, after the machinery pulls crowds hot curing, bending, bending and resistance to deformation. Corrosion resistance and long life. Glass fibre reinforced plastic are good composite. To acid, alkali, salt, oil and other corrosive media with special anti-corrosion features, rusting does not occur. Ordinary PVC life of 15 years, GRP a life expectancy of 50Years, and buildings with life, so using the trouble of FRP door and window replacement Windows and doors can be reduced, saving money. Tempered glass tempered glass is actually a prestressed glass, in order to improve the strength of glass, usually using chemical or physical methods on glass surface compressive stresses, glass first offset surfaces to withstand external stress, thus increasing the loading capacity, improves the tensile strength of the glass. There are two main advantages of tempered glass, first intensity compared with ordinary glass is increased several times, bending strength is 3~5 times of ordinary glass, impact resistance is common glass 5~10 times, increase strength and improve safety. Use tempered glass for safety is the second major advantages, its carrying capacity increases improving the fragile nature of even tempered glass failure also showed no sharp debris, greatly reduces the harm to humans. Thermal shock resistance of glass property two or three times the increase is compared with ordinary glass, can withstand 150LC variations in temperature, has obvious effect on preventing thermal breakage. Tempered glass is made of ordinary flat glass or float glass process becomes. General requirements of flat glass to use selected products or product; float glass excellence or grade is required. Production of tempered glass technology, there are two: one is an ordinary flat glass or float glass under certain conditions, by quenching or processed into wind quenching method. Another is ordinary plate glass or float glass by ion-exchange method, the glass surface composition changes is made by forming a laminate surface stress layer processed. Tempered glass has a high resistance to shocks (four to five times higher than ordinary flat glass) and flexural strength (5 times times higher than ordinary flat glass), good thermal stability and a smooth, transparent and can be cut and so on. In case of strong impact damage, debris dispersed fine granules, no sharp edges and corners, it is also known as safety glass. Shape into flat tempered glass and curved tempered glass tempered glass. Flat tempered glass thickness 4, 5, 6, 8, 10, 12, 15, 19mm, eight species of curved tempered glass thickness, 5, 6, and 8mm three. Tempered glass by its appearance is divided into: excellent products, qualified product categories. Tempered by fragmentation status include: categories I, II and III.
