The building insulation material fiberglass mesh is made of glass fiber woven fabric as the base material, and is coated with polymer emulsion. Therefore, it has good alkali resistance, flexibility and high tensile resistance in longitude and latitude. It can be widely used for thermal insulation, waterproof and crack resistance of internal and external walls of buildings. The fiberglass mesh is mainly alkali resistant fiberglass mesh. It is made of medium alkali free glass fiber yarn (mainly composed of silicate and good chemical stability) and twisted with a special organizational structure - leno tissue, and then subjected to high-temperature heat setting treatment such as alkali resistant solution and reinforcing agent. The main uses of fiberglass mesh are widely used in wall reinforcement materials (such as fiberglass mesh, GRC wallboard, EPS internal and external wall insulation board, gypsum board, waterproof coiled material cloth, asphalt roof waterproof, fireproof board, building caulking belt, etc.).
Pasting method of fiberglass mesh:
1. A specially assigned person must be responsible for the preparation of polymer mortar to ensure the mixing quality.
2. Turn the end of the barrel counterclockwise and re stir the adhesive with a mixer or other tools to avoid separation of the adhesive. Stir appropriately to avoid quality problems.
3. The mixing ratio of polymer mortar is: KL binder: 425# sulphoaluminate cement: sand (with 18 mesh sieve bottom): 1:1.88:3.25 (weight ratio).
4. After the dosage of cement and sand is weighed in the bucket, it is poured into the iron ash tank for mixing. After mixing evenly, the binder is added according to the mix proportion for mixing. The mixing must be uniform to avoid segregation and porridge. Water can be added appropriately according to the workability.
5. Water is used for concrete.
6. Polymer mortar shall be prepared with use, and the prepared polymer mortar shall preferably be used up within 1 hour. Polymer mortar shall be placed in a cool place to avoid sun exposure.
7. Cut the mesh sheet from the whole roll of glass fiber mesh according to the required length and width in advance, and leave the necessary overlapping length or the length of the overlapping part.
8. Cut in a clean and flat place, and the blanking must be accurate. The cut mesh must be rolled up, and it is not allowed to fold or trample.
9. A reinforcing layer shall be made at the external corner of the building, and the reinforcing layer shall be pasted on the innermost side, 150mm on each side.
10. When applying the first layer of polymer mortar, keep the EPS board surface dry and remove harmful substances or impurities from the board cotton.
11. Scrape a layer of polymer mortar on the surface of polystyrene board, the scraped area shall be slightly larger than the length or width of the fiberglass mesh, and the thickness shall be about 2mm. Except for those with edge wrapping requirements, polymer mortar is not allowed to be painted on the side of polystyrene board.
