What are the production processes of glass fiber mesh cloth
Glass fiber mesh cloth is based on glass fiber woven fabric, which is impregnated with polymer anti-emulsion coating. As a result, it has good alkali resistance, flexibility, and high tensile strength in the warp and weft directions, and can be widely used in building interior and exterior wall insulation, waterproofing, and crack resistance. So what are the production processes of glass fiber mesh cloth? I have summarized a few points:
1. Introduced 14.5% ~ 16.7% of zirconia and 6% of titanium dioxide into the glass composition, melted at a high temperature of 1600 ° C, and made into continuous filaments by platinum leakage drawing, and then twisted and twisted into textile glass fibers. During the process, the monofilament is coated with a polymer water-soluble epoxy resin and a coupling agent to meet the affinity of the glass fiber mesh cloth with the alkali-resistant polymer during post-processing.
2. In order to further improve the safe and stable durability of the alkali-resistant glass fiber mesh cloth, the styrene-butadiene rubber and pure acrylic emulsion are coated again after being knitted into a leno shape, and the temperature is controlled by constant temperature and constant speed and tension Fully (this process is an alkali-resistant coating technology developed by BASF in Germany for alkali-free glass fiber mesh cloth) in the early stage, it can effectively resist the erosion of glass fiber mesh cloth during the hydration period of polymer mortar Ca (OH) 2. After coating, the anti-sliding strength of the grid cloth junction is 3.5 ~ 4.5N.
3. In addition to the alkali-resistant coating of the glass fiber mesh cloth, the main alkali-resistant route is to form a zirconium and titanium ion mixed film on the surface of the fiber to prevent the alkaline substance from eroding. With time, the chemical state of zirconium gradually stabilizes. As shown in Table III, the alkali resistance retention rate of alkali-resistant glass fiber mesh cloth is greater than 85%, which is much higher than other glass fiber alkali-resistant coated mesh cloths, so we can also call it natural alkali-resistant glass fiber mesh cloth .
The above is the production process of glass fiber mesh cloth. Welcome to consult.
