Acid resistant Calcium Carbonate, Process for preparing the same and Method for improving the optical properties of paper alevemente neutral acid.

摘要

This paper introduces an improved form of anti acid calcium carbonate, which can be used as the input material in the production of low acid diphenyl oxide neutral paper, and introduces the process of producing this kind of anti acid calcium carbonate. This acid resistant calcium carbonate, based on the dry weight of decachlorocarbonate and calcium carbonate, mixes at least 0.5% to 10% of the aluminum salt. The favorite aluminum salt is aluminum sulfate, aluminum chloride,And PVC. In addition, the paper properties of neutral to slightly acidic surface were enhanced by adding the calcium carbonate.
