How to distinguish the quality of mesh cloth

Here is how to distinguish good and bad mesh cloth: 1. The worst glass fiber mesh cloth usually has a market price of around 1.00 yuan to 1.60 yuan. It breaks after being folded twice. The production process is clay crucible drawing. Glass fiber is usually made of waste glass such as beer bottles. It is a production process prohibited by the state, and the surface coating is not alkali-resistant emulsion. From an intuitive point of view: the workmanship is relatively rough, and it is generally sold in rolls in the market. There is often a lack of length, the weight is easy to shift, and it is easy to stab the skin. This type of mesh cloth is used in the insulation weight is insufficient, the joints are not firm, and it usually loses strength after two months. If the mortar is knocked off and the mesh cloth is taken out, as long as it is gently crushed, the glass fiber yarn will become powder.

2. There is also a kind of imitation platinum glass fiber mesh cloth, but it is also difficult to judge when it is waste. The selection of glass is through the plate broken glass, also called mixed silk yarn. This is a better imitation, often some flat glass fibers with good transparency. The fiber diameter is relatively thin. Authenticity, but its quality can never meet the requirements of truly alkali-resistant mesh cloth in the exterior wall insulation.

3. Standardized mesh cloth with good quality has good alkali resistance regardless of the material selection. The excellent ones are more particular about the alkali resistance of the coating and the high tensile strength in the warp and weft directions. The platinum and weaving process of the emulsion coating are all based on glass fiber. The product has a good feel and good construction compliance, which greatly reduces the amount of plastering mortar.

4. Alkali-resistant internal insulation fiberglass mesh cloth external insulation system range:

A. External wall usually uses: 3X3 45g, 5X5 80g

B. External wall board system uses: 5X5 130g, 5X5 145g

C. External wall glue powder particle system uses: 5X5 160g

D. External wall tile finish or insulation layer below two meters: 3X7 10 300g
