asphalt
Asphalt is the main waterproof function in the tiles, pure asphalt itself is a paste-like objects, and very easy to heat expansion and contraction of the impact of poor stability, the application of glass fiber tiles on the need to change its high temperature , And stability, there are two main ways to change the nature. One is to add chemicals in the asphalt, so that the shape of the asphalt change: the other is through the chemical reaction, from the molecular structure to change the asphalt properties, which become modified asphalt. Oxidation of asphalt in all aspects of performance than modified asphalt much higher in the country asphalt is mainly modified asphalt, foreign products are mainly oxidized asphalt.
Fibrous tiles of the carcass
Fibrous tiles of the carcass selection and application, related to the strength of asphalt shingles, tile durability, crack resistance, reverse osmosis and tile material is inseparable, so the carcass material is the pros and cons Asphalt tile quality one of the main factors. Fiberglass full name for the glass asphalt shingles, as the name suggests, the core carcass for the glass fiber tires. At the same time in the national standard 5.2 clearly stated: the use of glass fiber felt is low alkali or alkali glass fiber, to meet the GB / T 18840 2002 in the 5. 1,5. 5. 2 requirements, the basis of mass basis Should not be less than 90g / m2.
