The main difference between external wallthermal insulation mesh and interior wall mesh is in material. External wall thermal insulation mesh generally employs middle-alkali or alkali-free mesh and as raw materials, and then is formed into alkali resistant mesh after drying when coated with many layers. Then this product is very stable and has great strength,
External wall insulation alkali-resistant fiberglass mesh adots middle-alkali or alkali-resistant fiberglass mesh as substrate and then coated with modified acrylate copolymer adhesive solution. It is characterized by lightweight, high-strength, heat resistance, alkali-resistance, waterproof, corrosion resistance, resistance to cracking, and dimensional stability. It can effectively avoid tension contraction of the whole surface of floated coat and crack caused by an external force, thin mesh is often used in wall renovation and interior wall insulation. Mesh: 5mm * 5mm, 4mm * 4mm. gram?weight 80g --- 165g /㎡. Width: 1000mm ---- 2000mm. Length: 50m-300m or according to customer's requirements.
Fiberglass mesh uses glass fiber woven fabric as the substrate, and is immersed and coated by polymer emulsion resistance. Thus having good alkali resistance, flexibility and high warp-wise and weft tensile strength, it can be widely used in building internal and external wall insulation, waterproof, cracking and so on. Fiberglass mesh is mainly based on alkali-resistant fiberglass mesh, it uses the C or E-glass fiber yarn (main component is silicate which has good chemical stability) , twisted by special organizational structure-- leno weave, and then experiences high temperature heat processed through anti-alkaline, and enhancers. Alkali-resistant fiberglass mesh is based by middle-alkali or alkali-free glass fiber woven fabrics,and is processed by alkali resistant coating. The product is excellent in strength, adhesion, docile nature, positioning, which is widely used in enhanced wall and thermal insulation and waterproof of external wall.
