Why to carry out paper coating processing
Why to carry out paper coating processing

A: After calendering, the paper fiber is no longer loosely arranged, but has a certain degree of tightness, but the surface smoothness still can not meet the requirements of high-grade fine printing.   The surface uniformity of uncoated paper is poor. After printing, the ink color is uneven, and the glossiness is low. It can not restore the fine dot, resulting in layer loss, and the uniformity of the field part of the…

The functions of paper chemical auxiliaries
The functions of paper chemical auxiliaries

In order to meet the needs of some special uses of paper, various types of non-fibrous additives are often mixed in the pulp or paper. According to its use, it can be roughly divided into the following categories: ① Wet strength agent. To increase the wet strength of paper sheets. ② Dry strength agent. To improve the paper's dry strength (ring crush compression resistance and bursting strength). ③ Retention agent. To reduce the loss of…

What are the effects of surface sizing on the properties of printing paper
What are the effects of surface sizing on the properties of printing paper

① It can increase water resistance and surface strength of the paper and reduce surface picking in offset printing; ② It can improve paper printability. If there is too little glue on the surface, the paper will absorb too much binder in the ink during printing, resulting in dullness. On the contrary, if there is too much glue on the surface, it will slow the drying rate of the ink, resulting…
