The process of making Drywall Tape manufacturers is very strict

Speaking of Drywall Tape, everyone must be very unfamiliar with this term. In fact, it can be seen everywhere in our daily lives, such as being used as wall reinforcement materials, reinforced cement products, fireproof boards, waterproof membrane cloth, etc. Today, Drywall Tape manufacturers will mainly explain to you the main production processes of Drywall Tape. Exterior wall insulation board is also called horizon building exterior wall decorative integrated board. It is made of polymer mortar, Drywall Tape, flame-retardant molded polystyrene foam board (EPS) or extruded board Drywall Tape, which is made of medium alkali or non-alkali It is based on fiberglass woven fabric and treated with alkali-resistant coating.

1. The Drywall Tape manufacturer introduces 14.5% to 16.7% zirconium dioxide and 6% titanium dioxide into the glass composition. After melting at a high temperature of 1600°C, it is made of platinum leak-drawn into continuous filaments. Spliced and twisted into textile glass fibers, the single filaments are coated with polymer water-soluble epoxy resin and coupling agent during the drawing process to meet the affinity of the Fiber Glass with alkali-resistant polymers during post-processing.
2. In order to further improve the safe, stable and durable performance of the alkali-resistant Fiber Glass, after the warp knitting is processed into leno shape, it is coated with styrene-butadiene rubber and pure acrylic emulsion again, and constant temperature, constant speed and constant tension control technology is used to make it fully adhered. It can effectively resist the erosion of the Drywall Tape during the hydration period of polymer mortar Ca(OH)2 in the early stage. After coating, the anti-slip strength of the Drywall Tape intersection point is 3.5~4.5N.
3. In addition to the alkali-resistant coating, the main alkali-resistant way of the Drywall Tape is to form a mixed film of zirconium and titanium ions on the surface of the fiber itself to prevent the erosion of alkaline substances. As time goes by, the chemical state of zirconium gradually becomes stable. The alkali resistance retention rate of alkali-resistant Drywall Tape is greater than 85%, which is much higher than other Glass Fiber alkali-resistant coated Drywall Tape, so we can also call it natural alkali-resistant Drywall Tape.
