What role does the alkali resistance of glass yarn play?

An important indicator and testing content of the glass yarn is the alkali resistance of the glass yarn. The strength of this property is directly related to the service life of the glass yarn during use and to the safety of the building.

The reason why the alkali resistance of the glass yarn is so important is that during the construction process of the exterior wall insulation structure, the bottom mortar, surface mortar and other building materials coated are alkaline. If the alkali resistance of the glass yarn is not However, during actual use, due to being wrapped in mortar for a long time, it is very easy to be corroded by an alkaline environment, causing the Fiber Glass to become crispy and broken.
The alkali resistance of glass yarn consists of two aspects: material and coating. The Fiber Glass with the best alkali resistance is the golden pot emulsion Glass Fiber Fiber Glass that is woven with alkali-free gold pot glass fiber yarn and coated with alkali-resistant polymer polymer emulsion. This is what most Fiber Glass are made of. Choose the variety to use.
