The overlap width between the alkali-resistant mesh cloths is not less than 50mm, and the alkali-resistant mesh cloths at the inner corners should be overlapped with stubble, and the width is ≥50mm, and the outer corners are ≥200mm. During construction, the alkali-resistant grid cloth should be laid flat, without wrinkles, and the mortar fullness should reach 100%. At the same time, it should be smoothed, straightened, and the squareness and verticality of the yin and yang corners should be maintained.
The main function is to improve the mechanical strength of the surface layer, ensure the continuity of the resistance of the facing layer, disperse the shrinkage pressure and thermal insulation stress of the surface layer, avoid stress concentration, and resist the cracking of the surface layer caused by natural temperature and humidity changes and accidental impact. Therefore, alkali-resistant glass fiber mesh plays an important function and role in the external thermal insulation system, so the selection of a good glass fiber mesh is also an important part of ensuring the comprehensive quality of the external thermal insulation system.
The current national technical standard for external wall insulation (JG149-2003): the alkali-resistant tensile breaking strength of glass fiber mesh in both warp and weft directions shall not be less than 750N/50mm, and the tensile breaking strength retention rate of alkali-resistant mesh cloth shall not be less than 50%. , weight ≥ 130 grams per square meter.
For example the original construction period of ten months, after using this product, the construction period can be shortened by 2-3 months, and the construction cost can be effectively reduced. It can be said with certainty that as long as it is not artificially damaged by force, the wall corners can be used normally. Even if it is subject to a certain impact, it is difficult to damage, and the impact resistance of the corner can reach more than 100 kilograms.
In the original construction process, the construction of indoor and outdoor corners requires highly skilled professionals to do the construction, which requires high salaries.
