Fiberglass mesh cloth is made of fiberglass woven fabric and coated by polymer anti-emulsion immersion. Thus, it has good alkaline resistance, flexibility, and high tensile strength in the warp and weft direction, and can be widely used for insulation, waterproofing, and anti-cracking of internal and external walls of buildings. Fiberglass mesh cloth is mainly made of alkali-resistant fiberglass mesh cloth, which is made of medium and alkali-resistant fiberglass yarns (the main component is silicate, good chemical stability) twisted and woven by a special organizational structure – leno organization, and then heat-set at high temperature by alkali resistant liquid and reinforcing agent.
The main use of glass fiber mesh cloth is widely used in wall reinforcement materials (such as fiberglass wall mesh, GRC wall panels, EPS interior and exterior wall insulation boards, gypsum boards, waterproofing membrane cloth, asphalt roof waterproofing, fire prevention boards, construction of embedded seam tape and so on.
Fiberglass mesh cloth paste method:
1,.the preparation of polymer mortar must be specialized to ensure the quality of mixing.
2, Open the lid of the bucket by rotating it counterclockwise, and re-stir the binder with a stirrer or other tools to avoid separation of the binder, and stir moderately to avoid quality problems.
3, polymer mortar ratio is: KL binder: 425 # sulfur-aluminate cement: sand (with 18 mesh sieve bottom): = 1: 1.88: 3.25 (weight ratio).
4, cement, and sand with the number of barrels weighed and poured into the iron ash tank for mixing, mixing well, and then add the binder according to the ratio, mixing, mixing must be uniform, to avoid segregation, porridge-like. According to the ease of adding water can be appropriate.
5, water for concrete water.
6, Polymer mortar should be used with the matching, the matching of polymer mortar is best used up within 1 hour. Polymer mortar should be placed in the shade, to avoid sun exposure.
7, Cut down the mesh from the whole roll of fiberglass mesh according to the length and width required in advance, and leave the necessary lap length or overlap length.
8, Cut in a clean and flat place, the undercutting must be accurate, and the cut mesh must be rolled up, not allowed to fold and step on.
9, Do the reinforcement layer at the sunny corner of the building, the reinforcement layer should be pasted on the innermost side, 150mm on each side.
10, When applying the first polymer mortar, the surface of the EPS board should be kept dry and the harmful substances or impurities of the board cotton should be removed.
11, scrape a layer of polymer mortar on the surface of polystyrene board, the scraped area should be slightly larger than the length or width of the net cloth, and the thickness should be consistent by about 2mm, in addition to the requirements of the edge of the polymer mortar is not allowed to be coated with polystyrene board on the side.
12, After scraping the polymer mortar, the netting should be arranged on it, the curved surface of the netting towards the wall, from the center to the four sides of the application of flat, so that the netting is embedded in the polymer mortar, the netting should not be wrinkled, to be the surface dry, and then apply a layer of polymer mortar on it, the thickness of 1.0mm, the netting should not be exposed.
13, mesh perimeter lap length shall not be less than 70mm, in the part that is cut off, should be used to fill the net lap, lap length shall not be less than 70mm.
14, doors and windows around the bladder should be done to strengthen the layer, strengthen the layer of mesh cloth paste in the innermost. If the outer skin of the door and window frames and the surface distance between the base wall is greater than 50mm, the grid cloth and the base wall paste. If the distance is less than 50mm, the mesh cloth should be pasted with the base wall. The grid cloth laid on the large wall should be embedded in the outside of the door and window frames to stick.
15, doors and windows at the corners, in the standard network after application, and then in the doors and windows at the corners of a piece of 200mm × 300mm standard network, and the corner of the window bisecting the line into a 90-degree angle to be placed, affixed to the outermost side, to strengthen; in the shaded corners of a piece of 200mm long, the width of the window bladder appropriate standard mesh affixed to the outermost side.
16, Below the first floor sill, to prevent the damage caused by the impact, should be placed first to strengthen the type of mesh, and then place the standard type of mesh. The reinforcing mesh cloth should be butt jointed.
17, The construction method of placing the reinforcing layer is the same as that of standard-type mesh cloth.
18, The mesh cloth pasted on the wall should be covered with the mesh cloth of the overturned package.
19, mesh cloth was applied from top to bottom, synchronized construction was first applied to strengthen the type of mesh cloth, and then the standard type of mesh cloth.
20, mesh after sticking should be prevented from rain or impact, easy to collide with the corner of the sun, doors, and windows should be taken to protect measures, take anti-pollution measures on the port parts of the material, the occurrence of surface damage or contamination must be dealt with immediately.
21, after construction, the protective layer can not rain within 4 hours.
22, the protective layer after the final set of timely water spray maintenance, day and night average temperature above 15 ℃ shall not be less than 48 hours, and less than 15 ℃ shall not be less than 72 hours.
