摘要: Deinking of impact and nonimpact printed paper is accomplished by repulping defibering the in an alkali aqueous medium containing a deinking chemical to form ink pulp medium. The presence causes separation particles from fibers. Removal screening, flotation, forward cleaning, reverse washing mechanical dispersion procedures produce substantially free This has speck removal brightness level sufficient high-grade recyclable grade product. invention provides composition comprised mixture one or more solvents, nonionic anionic surfactants, capable high all types paper.
