Asphalt shingles asphalt shingles are the main raw material of new high-tech waterproof materials are also used in the construction of a new roof roofing materials, asphalt shingles range of use not only for the villa, which can be used as long as it satisfies the requirements of construction : roofing cement thickness of not less than 100mm, wooden roof structure is not less than 30mm of any building, addition to all the features of tile, it is also characterized in particular to fit any shape of roofing and roof slope 0-90 degrees. Asphalt is a glass fiber mat for the matrix, after dipping high-quality asphalt, no side cover color ore pellets, on the other hand sprinkle tile roofing sheet-like material made in isolation, and it has good waterproof decorative features and rich colors, forms, fine light surface, simple construction and so on. Asphalt shingles main components: sand, asphalt, glass, fillers, other chemical agents. 1, raw bitumen: There are three types of asphalt (road asphalt, blown asphalt, modified asphalt) (1) road asphalt Features: No. 100, also known as bitumen, road asphalt low melting point, at 30-60 degrees Celsius, the temperature difference, the summer is liquid at room temperature, the oil heavy, volatile, resulting in thinner tile is easy, life is short. Advantages: viscous, and more for asphalt road, and the low price, is used by most third-rate manufacturers. (2) the oxidation of asphalt Features: also known as the 10th pitch, also known as solid bitumen, temperature resistance, less volatile, thin tile is not easy, but the price is relatively high, Fuchun using asphalt shingles blown asphalt. Pros: good aging resistance, long service life. (3) modified bitumen characteristics: split by exposure to the sun can be re-bonding, but easy to drop sand, used for waterproofing membrane, at present there are very few domestic use of the modified asphalt. 2, sand: sand include :( low - acrylic paint stain, high temperature sintering sand stained, natural sand) (1) low temperature - acrylic paint stain Note: The paint stained 6-12 months full-fade, showing gravel bottom Color (general background is white), some third-rate manufacturers to low sales is to use stained sand. (2) high temperature sintering temperature sintering sand sand dyed and stained with the following categories: 1, domestic sintering sand, color 2--3 February, Jiangyin produce sintered sand mining phosphorus (French-owned), color 3--5 In March, the United States double tile sand imported from the United States, color 3--8 years; no domestic manufacturers currently use. (3) direct natural sand crushed natural rock, made without artificial dyeing natural sand (rock character), natural colors, intimate, lasting color retention. 3, glass fiber mat fiberglass mat comprises :( compound tires, polyester tire, tire fiberglass) 1) compound tires, 0.6 yuan / square, is disabled, the equivalent of adding a non-woven fabric, tearing up and down two. 2) polyester tire, GB is not recommended. 3) fiberglass tires, the national standard 90 g / square feet or more. Under the same thickness, the glass fiber mat is too little asphalt. 4, packing filler mainly composed :( calcium carbonate, lime) 1) calcium carbonate, calcium including GCC and light. Cod using TSP (tiles can increase weight, improve wind performance).
