The glass fiber mesh cloth is based on a glass fiber woven fabric and is coated with a high molecular weight emulsion-resistant soak. Therefore, it has good alkali resistance, flexibility and high tensile strength in the warp and weft directions, and can be widely used for thermal insulation, waterproofing, and crack resistance of internal and external walls of buildings. The glass fiber mesh cloth is mainly made of alkali-resistant glass fiber mesh cloth, which is made of medium-alkali-free glass fiber yarn (the main component is silicate and has good chemical stability) and is twisted and woven by a special tissue structure-leno tissue. After high-temperature heat setting treatment such as anti-alkali solution and enhancer.
