How to identify the quality problems of glass rod

The overlap width between glass rod should not be less than 50mm. The glass rod at the inner corner should be overlapped with a width of ≥50mm and at the outer corner ≥200mm. During construction, the glass rod should be laid flat and wrinkle-free, and the mortar should be 100% full. At the same time, it should be smoothed, straightened, and the squareness and verticality of the inner and outer corners should be maintained.

1. The market price of the worst glass rod is usually around 1.00 yuan to 1.60 yuan. Its Fiber Glass is usually made of 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 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. It often has insufficient length and gram weight. It breaks after two folds. The joints are not firm and easy to shift, and it is easy to pierce the skin. This type of glass rod used in the insulation layer generally loses its strength after two months. If the mortar is knocked off and the glass rod is taken out, the Fiber glass yarn will become powder with a light grind.
2. There is also a kind of imitation platinum glass rod, also called mixed silk yarn. This is a better imitation of Fiber Glass, but the waste glass is usually some flat broken glass with good transparency, and the fiber diameter is relatively thin. It is sometimes difficult to judge its authenticity from the surface, but its quality cannot meet the requirements of real glass rod in exterior wall insulation.
3. Standard high-quality glass rod all use platinum Fiber Glass as the base material, and they are more particular about the selection of materials and the weaving process. The coating emulsions used have good alkali resistance. Excellent alkali resistance and high tensile strength in warp and weft make the product feel good and have good construction compliance, which greatly reduces the amount of plastering mortar.
