Teach you how to test the performance of Fiberglass Cloth

For the detection of Fiberglass Cloth performance, the following will explain several methods for detecting the main performance of Fiberglass Cloth. First, the state of the Fiber Glass in the container is detected. Open the container and stir it manually. A small amount of precipitation is allowed at the bottom of the container. It is easy to mix after stirring, which can be defined as "no hard lumps after stirring".

For water resistance, the Fiberglass Cloth's resistance to water is tested. The test method is to apply the Fiberglass Cloth on the plaster layer. Under the specified conditions, the Fiberglass Cloth is soaked in distilled water. 2/3 of the Fiberglass Cloth is immersed in water, and 1/3 is placed above the water surface. After soaking for 96 hours, check whether the surface of the Fiberglass Cloth is white, loses gloss, bubbles, falls off, etc. If not, the Fiberglass Cloth passes the test of water resistance.
For alkali resistance, the Fiberglass Cloth's resistance to alkaline substances is tested. The test method is to construct the Fiberglass Cloth on the asbestos board. Under specified conditions, the Fiber Glass is immersed in a certain concentration of alkali solution. The test method is the same as the water resistance test method of the Fiberglass Cloth. 2/3 of the Fiberglass Cloth is immersed in water and 1/3 is placed above the water surface. Generally, after soaking for 48 hours, observe whether the Fiberglass Cloth has loss of gloss, bubbling, shedding and other phenomena.
