How to identify quality problems with glass yarn

1. The market price of the worst Fiber Glass is usually around 1.00 yuan to 1.60 yuan. Its Fiber Glass is usually made of some waste glass from beer bottles. The production process is clay crucible drawing, which is a production process prohibited by the state. The surface coating is also not an alkali-resistant emulsion. From an intuitive point of view: the workmanship is relatively rough, and generally sold in large quantities in the market. The length is often insufficient, the weight is insufficient, and it breaks after folding twice. The joints are not strong and easy to shift, and it is easy to puncture the skin. This type of glass yarn generally loses its strength after two months when used in the insulation layer. If the mortar is knocked out and the glass yarn is taken out, the fiberglass yarn will turn into powder with just a slight grinding.

2. There is another kind called imitation platinum glass yarn, also called mixed silk yarn. This is a relatively good imitation of Glass Fiber, but it is usually made from flat broken glass with good transparency, and the fiber diameter is relatively thin. Sometimes it is difficult to judge its authenticity from the surface, but its quality cannot meet the requirements of real alkali-resistant glass yarn in exterior wall insulation.
3. Standard high-quality Fiber Glass uses platinum glass fiber as the base material. Both the selection of materials and the weaving process are very particular. The coating emulsions used have good alkali resistance. The excellent alkali resistance and high longitudinal and latitudinal tensile strength make the product have good hand feel and good construction conformity, and can greatly reduce the amount of plastering mortar.
4. The scope of use of glass yarn in the external insulation system: A. The internal insulation of the external wall usually uses: 3×3×45 grams, 5×5×80 grams. B. The external wall panel insulation system uses: 5×5×130 grams. ,5×5×145g
