Procurement roofing tile "fiberglass asphalt shingles," notes: how to distinguish between fiberglass and polyester tire tread, compound tires? I. Description of asphalt shingles asphalt shingles, also known as glass tile, shingles, (full name tires fiberglass asphalt shingles). Asphalt shingles is a new high-tech waterproof materials are also used in the construction of a new roof roofing material. Asphalt roofing shingles are used in the construction of a new type of roofing materials. The use of asphalt shingles is not only for the house, it can be used as long as it meets the construction requirements of: cement roofing thickness of not less than 100mm, wooden roof structure is not less than 30mm of any building, in addition to all the features with the tile, it Another feature is especially to fit any roof slope and shape of the roof 0-90 degrees. Second, the fiberglass asphalt shingles major tire components: sand, asphalt, fiberglass, fillers, other chemical agents. Glass fiber mat (an important part of fiberglass asphalt shingles) fiberglass mat comprises: (compound tires, polyester tire, fiberglass tire) 1, compound tires, 0.6 yuan / square, is disabled, the equivalent of adding a non-woven fabric , you can tear down two. 2, polyester tire, GB is not recommended. 3, fiberglass tires, the national standard 90 grams / square above, generally 1.5 yuan / square. Third, fiberglass and polyester tire tread, the difference between compound tires: 1, fiberglass and polyester tire tread, tire compound is the difference between: (1) the tire is not the same cloth, fiberglass cloth fiberglass tire is adopted; (2) a polyester resin is used in tires, paper, grease and gasoline made of raw silk comprehensive; (3) compound tires are polyester and mesh fabric woven composite made, obviously the carcass layer network grid; (4) Then the degree of resistance to cold, fiberglass asphalt shingles can tire low temperature of minus 35 degrees, 90 degrees, where the use of high temperature without deformation without damage, while the polyester tire asphalt shingles can be used only at low temperatures, the highest resistance to cold degree at minus 35 degrees while the maximum temperature only 30 degrees under high temperature conditions, the tire-based raw materials containing gasoline ingredient in high temperature conditions not otherwise child-degree heat inside the volatile components of gasoline, can easily lead to weathering, rot, damage no waterproof; (5) compound tires asphalt shingles confined to local standards, in too cold or too hot place is not suitable. 2 life: child-produced fiberglass asphalt shingles can be used regardless of 30-50 years at high and low temperature conditions, polyester tire production base asphalt shingles can be used at low temperatures for 20-30 years, then 10 years of high-temperature around the base compound tires produced asphalt shingles can be used 10-20 years under certain temperature conditions, most available in 6-8 years is too cold or too hot environment. 3, Price: fiberglass and polyester tire tread, composite materials fiberglass tire tread on the most expensive, colored asphalt shingles produced at market price equal; 4, how to identify fiberglass and polyester tire tread, the tire compound Production of asphalt shingles: (1), can be distinguished from the thickness, tire manufacturing fiberglass asphalt shingles are controlled in thickness 2.6mm-2.7mm between the national standard, polyester tire, tire manufacturing composite thickness of asphalt shingles basic than the national standard range were 3.0mm and above; (2), can be distinguished from the weight, fiberglass asphalt shingles each of its child-piece weight of about 0.5 kg, polyester tire-based asphalt shingles per piece weight of about 0.7 kg, compound fetal weight based asphalt shingles or about 0.8 kg heavier. 5, to the factory site visits, fiberglass polyester tire than the tires, composite tires Rally. 6, polyester tires, asphalt shingles composite output viviparous easily torn, fiberglass asphalt shingles tire production out of a bad tear.
