Regarding the quality inspection of asphalt shingles, it is difficult for non-professionals to start the inspection. Today I will share with you how to manually inspect the quality of asphalt shingles so that you can easily identify the quality of asphalt shingles.
1. Fetal base inspection
Friends who have experience with asphalt shingles know that from the early development of asphalt shingles, composite tires and other tire bases are commonly used as tile base materials in many factories, but the tire base has poor weather resistance, poor aging resistance, poor water resistance, and better roof quality in the later stage. There is no guarantee, but professional asphalt shingle manufacturers will choose glass fiber base, which is dense and rich, strong in toughness, anti-aging, and excellent in wind resistance. The better way to distinguish is: the composite tire is rib-like, and the glass fiber base contains abundant glass fiber filaments, which can be seen by tearing off the tiles.
2. Asphalt selection
High-quality asphalt has no pungent or unpleasant odor.
3. Material color of colored sand
Put the colored sand in a glass cup, add a little dilute hydrochloric acid (you can replace it with vinegar), and boil for about 2 hours to imitate the situation of direct sunlight and acid rain in real life, and then observe the fading of colored sand.
4. Weather resistance
In the existing environment, the high and low temperature test is more convenient and quick. For example, the low temperature resistance test can be directly put the asphalt shingles into the freezer of the refrigerator, freeze them for several hours, and then take them out, and then observe whether there is sand falling, cracks, etc. Happening.
