How to distinguish the quality of glass rod

1. The market price of the worst glass rod is usually around 1.00 yuan to 1.60 yuan, and it breaks after being folded twice. The production process is clay crucible drawing, and the Fiber Glass 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 glass rod is used in the insulation weight is insufficient, the joints are not firm, and it generally loses its strength after two months. If the mortar is knocked off and the glass rod is taken out, as long as it is gently rolled, the Fiber glass yarn will become powder.

2. It is also difficult to judge when the glass rod is waste. The glass is selected from the broken glass on the upper plate, also called mixed silk yarn. This is a better imitation, often some flat Fiber Glasss with good transparency. The fiber diameter is relatively thin. Authenticity, but its quality does not meet the requirements of real alkali-resistant glass rod in the exterior insulation of the exterior wall in any case.
3. Standardized glass rod with good quality has good alkali resistance regardless of the material selection. The excellent ones are all exquisitely coated with alkali resistance and high tensile strength in warp and weft directions. They all adopt platinum and weaving process, and the emulsion coating is based on Fiber Glass. This makes the product have good hand feel and good construction compliance, and greatly reduces the amount of plastering mortar.
