Alkali free fiberglass cloth is made of glass fiber woven fabric as the base material. It is widely used in wall reinforcement materials, reinforced cement products, reinforced plastics, and rubber products skeleton materials by the polymer emulsion anti soaking coating. Many friends are using fiberglass cloth, but how should the glass fiber cloth distinguish the good from bad?
Method 1: judge the quality by observing the glass fiber cloth on the surface. Glass fiber cloth with good quality has clean surface, even and straight warp and weft lines, good toughness and even mesh. The glass fiber cloth with poor quality has uneven mesh and poor toughness.
Method 2: the glass fiber cloth with good chemical stability and good quality has relatively stable chemical properties, alkali resistance, acid resistance, water resistance, cement corrosion resistance, and other chemical corrosion resistance, so it is safe to use.
Method 3: judge the quality of glass fiber cloth by color. The color of glass fiber cloth with good quality is glossy and uniform, while the glass fiber cloth with poor quality is not only touching, but also dark and turbid.
Method 4: judge the quality of glass fiber cloth by stretching glass fiber cloth. Good glass fiber cloth is not easy to deform, and it can be restored by stretching, while the glass fiber cloth with poor quality can hardly be restored to its original state by stretching, which affects the normal use.
