Overview

Urumqi 120g grid cloth acid and alkali resistant roll quotation wall grid cloth, also known as glass fiber wall grid cloth, is a new type of alkali resistant product made from medium alkali or alkali free glass fiber yarn, woven into glass fiber grid cloth as the substrate, and then coated with acrylic copolymer solution and dried. This product has the characteristics of stable structure, high strength, good alkali resistance, corrosion resistance, crack resistance, etc., enhanced effect, and simple and easy construction. It is mainly suitable for reinforcing and cracking the inner and outer surfaces of cement, gypsum, walls, buildings, and other structures, and is a new type of building material for external wall insulation engineering.

Product Details

Urumqi 120g grid cloth acid and alkali resistant roll quotationAlkali resistant fiberglass mesh cloth is a reinforcing material for the exterior wall insulation surface layer. Its main function is to improve the mechanical strength of the surface layer, ensure the continuity of the resistance of the decorative layer, disperse the shrinkage pressure and insulation stress of the surface layer, avoid stress concentration, and resist surface cracking caused by natural temperature and humidity changes and accidental impacts. Therefore, alkali resistant fiberglass mesh plays an important role in the external insulation system, and the selection of good fiberglass mesh is also an important component to ensure the comprehensive quality of the external insulation system. The current national standard for external wall insulation technology (JG149-2003): The tensile strength of fiberglass mesh in the warp and weft directions shall not be less than 750N/50mm, and the retention rate of tensile strength shall not be less than 50%. The weight per square meter shall be ≥ 130 grams. The tensile strength of JG158-2004 fiberglass mesh in both warp and weft directions shall not be less than 1250N/50 mm, and the retention rate of alkali tensile strength shall not be less than 90%. The weight per square meter shall be ≥ 160 grams. At present, the grid cloth used for external wall insulation systems in the Chinese market weighs around 130g per square meter, and its strength is generally low. Its normal fracture strength is only 1000N/5cm, or even lower. Therefore, standardization is required for the technical indicators of the grid cloth for external wall insulation projects, and qualified confirmation must be made for the purchased alkali resistant fiberglass grid cloth before use.Urumqi 120g grid cloth acid and alkali resistant roll quotationWhen controlling cracks in external wall insulation, it is not only required that the insulation layer material has a certain tensile strength and ultimate tensile strength, but also that the crack resistant protective layer material has sufficient tensile strength. Therefore, when selecting alkali resistant fiberglass mesh fabric, it is necessary to pay attention to whether the tensile strength of the alkali resistant fiberglass mesh fabric itself meets the standards. The use of alkali resistant fiberglass mesh cloth composite in plastering mortar can effectively increase the tensile strength of the protective layer, and on the other hand, due to its ability to effectively disperse stress, it can disperse the originally wide cracks into many finer cracks, thus forming its crack resistance effect. The surface coating material and coating amount have important significance for the alkali resistance of fiberglass mesh, and the variety of fiberglass has a decisive effect on long-term alkali resistance.
