Glass fiber grid cloth is based on the material of glass fiber woven fabric, the polymer emulsion for coating. Which has a good alkali resistance, flexibility and fabric to high tensile resistance, can be widely used in building internal and external wall thermal insulation, waterproof, crack resistance, etc. Glass fiber grid cloth is given priority to with alkali resistant glass fiber grid cloth, it USES the alkali-free glass fiber yarn (ingredient is silicate, chemical stability is good) by the special organization structure, leno weave organization, after alkali resistance, strengthening agent high temperature to finalize the design process.
Glass fiber grid cloth is mainly used in wall enhanced materials, such as glass fiber wall grid cloth, GRC wall panels, EPS external insulation board, gypsum board, waterproof coiled material cloth, asphalt roofing waterproof, fire prevention board, building sealing belt and so on.
The construction method of glass fiber grid cloth:
1、 Making polymer mortar must be someone who's in charge, in order to ensure the quality of mixing.
2、Counterclockwise to open the top of the drum with agitator or other tools will binder to stir, avoid the separation phenomenon in a binder, mixing moderate, lest appear quality problem.
3、Polymer mortar mix proportion is: KL binder: # 425: sulphur aluminate cement sand (18 mesh bottom) : = 1:1. 88:3.25 (weight ratio).
4、Dosage of cement, sand barrels according to pour into a groove in the iron ash mixed, mix according to the mixture ratio after adding binder, stir, stir must be uniform and avoid segregation, gruel. According to the workability can be appropriately adding water.
5、Water for concrete with water.
6、Polymer mortar shall be used along with the match, match good polymer mortar is best used within 1 hour. Polymer mortar should be in a cool place, avoid sunlight exposure.
7、According to the need to advance length, width of fiberglass mesh cloth from the roll cutting a let down the nets, set aside the necessary lap length or the length of the overlap.
8、Under the cut clean and smooth, material must be accurate, cut good net cloth must be rolled up, are not allowed to fold, not allowed to trample.
9、Strengthen the floor in building external Angle place, strengthening layer should be posted on the inside, 150 mm per side.
10、Daub is the first time when the polymer mortar, should maintain EPS board face dry, remove the plate cotton harmful substances or impurities.
11、On polystyrene surface a layer of polymer mortar, by scraping the area should be slightly greater than the length or width of grid cloth, about 2 mm thickness should be consistent, in addition to the package edge requirement, polymer mortar are not allowed to apply in polystyrene board side.
12、After scraping the polymer mortar, grid layout should be on it, the curved surface of grid cloth toward the wall, from central to wipe TuPing, embedded in the polymer mortar makes the grid cloth, grid cloth should not buckling, treated surface, after dry again on it with a layer of polymer mortar, the thickness of 1.0 mm, the grid cloth should not be exposed.
13、Grid cloth around the lap length should not be less than 70 mm, at the site of the cut, mending their nets should be adopted for the lap, lap length shall not be less than 70 mm.
14、Doors and Windows flirt around should strengthen the layer, strengthen layer grid it on the inside. If the door window frame from skin and wall surface at the grass-roots level greater than 50 mm, mesh cloth and wall paste at the grass-roots level. If less than 50 mm to do turn packet processing. Great Wall laid grid cloth should be embedded in the door window frame lateral glued down.
15、Door window corners, in the standard network after the wipe, the corners of the door window again with a 200 mm x 300 mm standard network, with a 90 degree Angle bisector window placement, posted on the outside piece, to strengthen; The shade in place with a 200 mm long and width of the optimal window bang width standard mesh, stick on the outside.
16、Under a layer of window, in order to prevent the damage from the impact, should be enhanced grid cloth, the relocation standard grid cloth. Should strengthen the grid cloth docking.
17、For strengthening layer construction method is the same as the standard grid cloth.
18、Metope stickup grid cloth should be covered in the package grid cloth.
19、Top-down grid cloth to wipe, synchronous construction with enhanced grid cloth, first do standard grid cloth.
20、Grid cloth glue should prevent the rains washed out or after the impact, easy to collision, the Angle of the doors and Windows protection measures should be taken, feeding mouth parts take pollution prevention measures, surface damage or contamination should be dealt with immediately.
21、Layer 4 hours after construction can't be the rain.
22、Protection layer after the final set sprinkler maintenance in time, day and night when the average temperature is higher than 15 ℃ shall not be less than 48 hours, below 15 ℃ shall not be less than 72 hours.
