Aluminum silicate fiber cotton is a kind of heat preservation equipment with good properties. In the long-term use, the equipment may have some minor problems, such as cracks in the product. Next, the editor will analyze the reasons for everyone. Confused friends, let’s find out together:


1. Caused by too fine fiber fineness modulus and too high mud content;

2. The water absorption rate of the mortar of aluminum silicate fiber cotton is too high, and frost heave in winter causes cracks;

3. The mixing of aluminum silicate fiber products is uneven, resulting in stress due to inconsistent shrinkage;

4. The proportion of cement is too large and the label is too high, causing the aluminum silicate fiber cotton to shrink too much and too fast in the early stage;

5. The flexibility index is not enough and the elongation is small, which reduces the anti-deformation ability of aluminum silicate fiber products.

There are many reasons for the occurrence of cracks in aluminum silicate fiber cotton products. Finding the specific cause can effectively solve the problem, preventing similar problems from being encountered again in the future, and wasting costs. At the same time, in daily use, if you encounter this aspect Don’t panic.
