Test Drywall Tape steps and production requirements

Drywall Tape is a kind of decoration material that can solve the cracks in the wall. When decorating, use Drywall Tape to stick to the wall before applying putty, which can effectively prevent the wall from cracking.

1. Wall construction Drywall Tape: Its function can be summarized in a few words: to prevent wall cracks and cement mortar cracks.
2. Drywall Tape for inkjet printing: Drywall Tape is suitable for hanging paintings in trade shows and interior decoration, and is mostly used to make super-large signage advertisements and architectural advertisements.
3. Fiber Glass insulation effect: Generally, Drywall Tape has good alkali resistance. Drywall Tape without alkali resistance will almost never appear on the market. Glass itself is not alkali-resistant, so alkali-resistant ingredients are generally added. , so that fiberglass has good crack resistance and alkali resistance. And because of this strength and alkali resistance, Fiber Glass is important in insulation systems.
Drywall Tape has an expandable liquid resin system. Drywall Tape manufacturers use this method to produce phenolic foam products. Wet production of phenolic foam, its raw material synthesis and foam preparation technology are similar, but the method of controlling foam density is different. Dry phenolic foam is an expandable solid resin system based on thermoplastic resin.
Since high-rise buildings, transportation, ships, aviation, and aerospace technology have put forward strict requirements for synthetic foams with good thermal stability and flame resistance, phenolic foam has attracted widespread attention and rapid development of communications. People realize that the use of Drywall Tape to make thermal insulation materials have important practical value in the fields of high-rise buildings, heat insulation, and low-temperature cold preservation.
The unevenness of the Fiber Glass is the ratio of the length of the cloth that exceeds the specified low sag distance (that is, the uneven length of the cloth surface) to the length of the entire cloth, expressed as a percentage. The Drywall Tape manufacturer applies tension to the running Drywall Tape, and within a specified distance, measures and accumulates the length of the glass cloth exceeding the specified low sag distance and the length of the entire cloth.
