Calcium Carbonate, acid resistant, method to improve the optical properties of paper, neutral to slightly acid and neutral role acidoque understands.

摘要

Presents an improved form of Calcium Carbonate and acid resistant material to facilitate its use as an input to produce a neutral role alevemente acidAnd a process for producing Calcium Carbonate acid resistant.This Calcium Carbonate and acid resistant decalcio carbonate mixture comprises at least 0.5 to 10 percent, based on the dry weight of Calcium Carbonate, a Salt cationicAlong with at least 0.5 to 10 percent based on the weight of Dry Ash, calcium salt of an anion.It also presents a method to improve the optical properties of paper neutroa slightly acid by the addition of Calcium Carbonate to the same role as a neutral to acid CompRendeel Calcium Carbonate.
