Plus calcium sulfate process for filling in paper
Author:liming Post Date:2012-1-3
Calcium sulfate as a white high, low hardness, high temperature resistance, chemical resistance, and strong affinity with the polymer, non-toxic characteristics, plus fill in for the paper can bring significant strength advantage, however, calcium sulfate in aqueous solution or in moist air the hydration reaction will occur, leading to changes in crystal structure and performance, thus losing its original properties. If used directly for paper filler, its retention rate is very low, and dissolved in water calcium sulfate serious impact on the recycling of white water system, resulting in the production run issues.
Calcium sulfate is an ideal filler paper, will help to improve the optical properties and strength properties of paper. Calcium sulfate by appropriate modification of the surface, can significantly improve the retention rate in the wet, but also reflects the strength compared to calcium carbonate plus fill benefits.
Paper on the future market position of calcium sulfate, after filling the main focus on its added features, plus fill in for the paper in addition to providing excellent strength properties, we should also consider whether the same to the paper surface of the optical properties and performance have a positive impact, while the industrial by-products can be used to plaster processed into calcium sulfate to fill the paper plus the cost factor to consider is the need to focus on one aspect.
