What role does exterior wall insulation mesh play in exterior walls?
First of all, the exterior wall insulation mesh cloth is based on exterior wall insulation woven fabric and soaked in polymer anti-emulsion coating. As a result, it has good alkali resistance, flexibility, and high tensile strength in the longitudinal and latitudinal directions, and can be widely used for thermal insulation, waterproofing, crack resistance, etc. of interior and exterior walls of buildings. The exterior wall insulation mesh cloth is mainly alkali-resistant fiberglass mesh cloth. It uses medium alkali-free fiberglass yarn (the main component is silicate and has good chemical stability. It can also be used in cement, plastic, asphalt, marble, mosaic, and other wall materials.
14.5%~16.7% zirconium dioxide and 6% titanium dioxide are introduced into the glass composition. After melting at a high temperature of 1600°C, platinum is leak-drawn into continuous filaments, which are spliced and twisted into textile exterior wall insulation. During the drawing process, The medium monofilament is coated with polymer water-soluble epoxy resin and coupling agent to meet the affinity of the exterior wall insulation mesh cloth with the alkali-resistant polymer during post-processing. In addition to the alkali-resistant coating, the main alkali-resistant way of fiber mesh cloth is to form a mixed film of zirconium and titanium ions on the surface of the fiber itself to prevent the erosion of alkaline substances. As time goes by, the chemical state of zirconium gradually becomes stable. The alkali resistance retention rate of alkali-resistant exterior wall insulation mesh is greater than 85%, which is much higher than other exterior wall insulation and alkali-resistant coated meshes. Therefore, we can also call it a natural alkali-resistant exterior wall insulation mesh.
