The difference lies in the alkali resistance of the glass fiber used. At present, there are very few high-alkali glass fiber products in China, and the worst is medium-alkali. Because the glass itself is not alkali-resistant, anti-alkali ingredients are added to the glass fiber products when processing glass fiber products. Generally, zirconium dioxide is added to make the glass fiber have a certain tolerance to -OH.
The grid cloth produced with alkali-resistant glass fiber is alkali-resistant grid cloth, and so are others.
The alkali-resistant zirconia content is large, and the price of the mesh cloth is high-quality. Medium-alkali glass fiber yarn is also alkali-resistant after being coated with alkali-resistant coating glue, and the quality can be moderately priced.
Alkali-resistant fiberglass mesh
Mesh cloth specifications: according to the mesh: 0.5cm 1cm 1.2cm 1.5cm
Divided by width: 60cm 100cm
By weight: 80g——160g per square meter
According to glue: emulsion urine glue urine milk
Technical parameters of mesh cloth: the tensile breaking strength shall not be less than 750N/50mm, the retention rate of tensile breaking strength shall not be less than 50%, and the weight per square meter shall not be less than 130 grams
Mesh cloth implementation standard: the current national technical standard for external wall insulation (JG149-2003)
Mesh cloth is based on medium-alkali glass fiber, and coated with polymer alkali-resistant emulsion after spinning. The product has good alkali resistance and high tensile strength in warp and weft directions.
Grid cloth characteristics
It has a comfortable hand feeling, easy construction, significantly reduces the consumption of plastering mortar, excellent alkali resistance, and strong tensile strength in warp and weft directions.
Glass fiber mesh cloth has uniform mesh and smooth mesh surface. Trim the edges neatly. It has the characteristics of alkali resistance, high temperature resistance, enhanced heat preservation, crack resistance, moisture resistance, good tensile strength and corrosion resistance.
