Phenolic resin doctor blade is a non-metallic scraper made of phenolic resin as the matrix and reinforced with cotton cloth/glass fiber/carbon fiber. It is formed by hot pressing and has the core advantages of not damaging soft rollers, wear resistance, insulation, temperature resistance, and moderate cost. It is a mainstream cleaning/scraping component in industries such as papermaking, printing, dyeing, and sludge dewatering.
1. Forming and press section: Clean hard rubber rolls, wire drive rolls, cast iron rolls, chrome coating rolls, and stone rolls; Never damage the soft rubber roll/polyurethane roll.
2. Dryer section: clean the dryer cylinder and reel cylinder (in the medium and low temperature range); choose epoxy resin or metal doctor blade if in high temperature section.
3. Size press section and calendering section: Clean the size press roll and calendering roll (special for soft surface rolls).
Phenolic resin, also known as bakelite or bakelite powder, is English named phenolic resin, abbreviated as PF. This type of resin has a specific gravity between 1.25 and 1.30 and is produced by the polymerization reaction of phenol and aldehyde.
