Alkali-resistant fiberglass mesh is not an energy-saving material. It is just an auxiliary material used in exterior wall insulation projects. It plays a role in resisting cracks and increasing the strength of the mortar layer.
Alkali-resistant glass fiber mesh cloth is based on glass fiber 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. Fiberglass mesh is mainly alkali-resistant fiberglass mesh. It is made of medium-alkali-free glass fiber yarn (the main component is silicate and has good chemical stability) and is twisted and woven with a special organizational structure - leno tissue. After that, it undergoes high-temperature heat setting treatment such as alkali resistance and enhancer.
The main purpose is widely used in
1. Wall reinforcement materials (such as fiberglass wall mesh, GRC wall panels, EPS interior and exterior wall insulation boards, gypsum boards, etc.
2. Reinforce cement products (such as Roman columns, flues, etc.)
3. Special mesh for granite and mosaic, and marble back mesh.
4. Waterproof membrane cloth and asphalt roof waterproofing.
5. Reinforce the skeleton material of plastic and rubber products.
6. Fireproof board.
7. Grinding wheelbase cloth.
8. Geogrids for highway pavement.
9. Caulking tape for construction, etc.
Nowadays, it is necessary to insulate and plaster the energy-saving exterior walls of buildings to prevent cracking. Because the insulation dry mortar has low strength and a thickness of 30mm, it is easy to crack, so it is necessary to add mesh cloth and then cover it. Mesh cloth is woven with medium-alkali or alkali-free glass fiber yarn and coated with alkali-resistant polymer emulsion. Mesh cloth series products: alkali-resistant GRC fiberglass mesh cloth, alkali-resistant wall mesh and stone mesh cloth, and marble back-mesh mesh cloth. When a new house is handed over, it has not been built for a long time, so the settlement of the walls is not very good. At this time, there will be slight cracks at the intersections of light walls, beams, etc., and load-bearing walls as they settle. For lightweight walls, you can use kraft paper or denim cloth for processing.
Corner seams can be treated with strips of perforated kraft paper. Mesh strips are generally used for processing slightly larger gaps. Houses from older eras usually have brick or sand-gray walls, which are prone to cracks. Because there is airflow in the brick body, no one can avoid it. The use of patching and other methods can prolong the time for cracks to appear, but there is no guarantee that they will not crack completely.
