What are the raw materials for the production of fiberglass asphalt shingles?

Fiberglass asphalt shingle is a new tile-shaped roof waterproof material with high-quality glass fiber mat as the base, high-quality petroleum asphalt dipping surface, one side covered with calcined colored mineral pellets, and the other side with isolation material. Among them, the quality of glass fiber mat is directly related to the service life of asphalt shingles; and the formula of asphalt is very important, because the intensity of sun exposure throughout the year is different, the temperature difference is large, and the test of asphalt is greater, while asphalt shingles Generally, they are self-adhesive series, which requires that the tiles fixed on the roof perform the function of self-adhesive strips and stick to the roof by themselves under the premise of ensuring that the asphalt surface is not soft, not flowing, not hard and not broken. One of the technical indexes of asphalt shingles is also reflected here. The key to the expression of the technical content lies in how the technicians formulate the asphalt according to the different seasons. Only good quality formulas can be used for a long time; the choice of colored mineral materials is also very important. , Generally can be divided into quality from good to poor (cost from high to low): natural sand, ceramic sand, sintered sand (calcined sand), dyed sand. The quality of sand is related to the long-term exposure and wind blowing of asphalt shingles in the future. The color of the asphalt shingle fades and fades easily after the wiper, which directly affects the beauty of the asphalt shingle. Fiberglass asphalt shingles are the most widely used in the United States. About 80% of the houses use fiberglass asphalt shingles. It is in the development stage in China and will be widely used in the future, such as Shanghai, Hangzhou, Nanjing, etc. in recent years. The city’s "flat to slope" projects all specify the use of fiberglass tiles. Its most used functions are: good waterproof effect and beautiful appearance, light weight (low roofing capacity), easy construction, environmental protection, strong dust-proof and self-cleaning properties, and durability. Corrosiveness, other functions are just talking about it. Now that the use of asphalt shingles is increasing, many manufacturers use low-quality raw materials without hesitating to shout high slogans for profit, and the technology of new-born manufacturers is not up to the standard, so friends who buy it must keep their eyes open.
