配方類型: PAPER
配方說明: Another Method
配方組成: Sodium silicate/5.0
Soap/3.5
Sodium peroxide/2.0
配制方法: The silicate and peroxide are essential agents in detaching the ink from the fibers. The dispersing and suspending action of the silicate keeps the ink particles free for removal by flotation. The soap acts as a detergent, wetting the paper and washing the ink free of the pulp. The peroxide helps bleach the fibers.
