Introducing the method of pasting glass yarn

The main functions of the glass yarn are to improve the mechanical strength of the surface layer, ensure the resistance continuity of the surface layer, disperse the shrinkage pressure and thermal insulation stress of the surface layer, avoid stress concentration, and resist surface damage caused by changes in natural temperature and humidity and accidental impacts. Layer cracking. Therefore, glass yarn plays an important role in the external insulation system, so choosing a good glass yarn is also an important part of ensuring the overall quality of the external insulation system.

1. A dedicated person must be responsible for preparing polymer mortar to ensure the mixing quality.
2. Open the lid of the bucket by rotating it counterclockwise, and use a stirrer or other tools to re-stir the adhesive to avoid separation of the adhesive. Stir appropriately to avoid quality problems.
3. The mixing ratio of polymer mortar is: KL binder: 425# sulfoaluminate cement: sand (use 18 Fiber Glass sieve bottom): =1:1.88:3.25 (weight ratio).
4. Weigh the cement and sand in a measuring bucket and pour them into the iron ash tank for mixing. After stirring evenly, add the binder according to the mix ratio and stir. The stirring must be even to avoid segregation and porridge-like appearance. Water can be added appropriately according to the workability.
5. Water is used for concrete.
6. Polymer mortar should be prepared as needed. It is best to use up the prepared polymer mortar within 1 hour. Polymer mortar should be placed in a cool place to avoid sunlight exposure.
7. Cut the Fiber Glass from the entire roll of fiberglass glass yarn according to the required length and width, leaving the necessary overlap length or overlap length.
8. Cut in a clean and flat place. The cutting must be accurate. The cut Fiber Glass must be rolled up. Folding and stepping are not allowed.
9. Make a reinforcement layer at the sun corner of the building. The reinforcement layer should be attached to the innermost side, 150mm on each side.
10. When applying the first coat of polymer mortar, the EPS board surface should be kept dry and harmful substances or impurities in the board cotton should be removed.
11. Scrape a layer of polymer mortar on the surface of the polystyrene board. The scraped area should be slightly larger than the length or width of the glass yarn, and the thickness should be about 2mm. Except for those with hemming requirements, polymer mortar is not allowed to be applied. On the polystyrene side.
12. After scraping the polymer mortar, the grid should be arranged on it, with the curved surface of the grid facing the wall, and smooth application from the center to the surroundings so that the grid is embedded in the polymer mortar and the grid is not It should be wrinkled, and after the surface is dry, apply a layer of polymer mortar on it with a thickness of 1.0mm. The glass yarn should not be exposed.
13. The overlapping length around the glass yarn shall not be less than 70mm. In the cut parts, Fiber Glass patching shall be used to overlap, and the overlapping length shall not be less than 70mm.
14. A reinforcement layer should be made around the door and window wings, and the glass yarn of the reinforcement layer should be affixed to the innermost side. If the distance between the outer skin of the door and window frame and the surface of the base wall is greater than 50mm, the glass yarn should be affixed to the base wall. If it is less than 50mm, it needs to be turned over. The glass yarn laid on the large wall should be embedded in the outside of the door and window frames and glued firmly.
15. At the four corners of the door and window, after the standard net is applied, add a piece of 200mm to 300mm standard net on the four corners of the door and window, place it at an angle of 90 degrees to the bisector of the window corner, and stick it to the outermost side for reinforcement; Add a piece of Fiber Glass 200mm long and standard width to the window at the inner corner, and attach it to the outermost side.
