The quality of the mesh fabric manufacturers can be seen at a glance. There are common unfavorable phenomena when cracks appear on the surface of the wall. There are two main reasons for this phenomenon: one is drying shrinkage, the other is temperature difference deformation, and the exterior wall insulation In the surface layer, the crack caused by the temperature difference deformation is mainly caused, and the reason for the deep layer is caused by the mismatch of the materials and the mismatch between the materials of the layers.

There is a kind of outer wall mesh cloth called imitation platinum. But sometimes it is more difficult to judge the authenticity, and its quality does not meet the requirements of the real alkali-resistant mesh cloth from the outside in the external wall insulation. The fiber diameter is relatively thin, and the glass is selected to pass through the cullet, also called the mixed yarn. This is a counterfeit flat glass fiber that is often well-transparent. The standard-quality outer wall mesh fabric has good alkali resistance in the selection of materials. The advantage is that all alkali resistance and high latitude and longitude tensile strength are in platinum. The woven emulsions are all made of glass fiber. The product has good hand feeling and good construction conformability, and the amount of plastering mortar is greatly reduced.

The worst glass fiber façade mesh cloth is very cheap, it breaks at two folds, and the production process is ceramic enamel drawing. The glass fiber fiber is usually made of waste glass of some beer bottles. It is a production process prohibited by the state, and the outer coating is not an alkali-resistant emulsion. From the visual point of view: the work is relatively rough, generally sold in the market theory, often lack of length, easy to shift, and easy to stab the skin. Such a mesh cloth is used in the case of insufficient insulation weight, and the strength of the contact layer is generally lost after two months. If the mortar is knocked out and the mesh cloth is taken out, the glass fiber yarn will be gently ground. Become a slight shape.
