Product Description

Because NPCC has low oil absorption, fine and uniform particles, good dispersion, high whiteness, low hardness, small and non-toxic wear, odorless, tasteless, and good dispersion etc., in the paper industry, NPCC can increase the brightness of paper, solid structure, profit writing, coating uniformity, low friction, easy to dehumidification and drying easier. As the world’s paper industry from the early 80s last century, the successful shift from acidic to alkaline process technology material used to fill a revolution in change: NPCC and other pigments instead of wood pulp can improve the brightness of paper not permeability, porosity, bulk density, etc.. At present, paper formulations increase the use of NPCC from 5%-10% to 30%. NPCC can be widely used in high-grade paper products.

Advantage:

1. Have high opacity and high brightness, can increase the whiteness and opacity of paper.

2. Enable the mill to use more filler and less pulp, can greatly reduce production costs.

3. Fine grain size and uniform of NPCC, wear on the machine is small, and the production of paper products can be more uniform, smooth.

4. High oil absorption of NPCC, can improve the color fastness of color paper.

5. Fill up the neutral paper or cardboard, can improve the tightness of paper or paperboard.

Therefore, NPCC for paper fillers have higher bulk density, good plasticity and softness, delicate surface of paper, can significantly improve the performance of paper, so papermaking enterprises to obtain significant economic benefits.

The use in the surface of sizing

NPCC with good properties of high brightness, large surface area, surface activity, high strength and hardness. In the surface sizing agent added to NPCC, can be high gloss and high ink absorbency of the paper, and can improve the smoothness of paper. NPCC as a pigment surface sizing of paper, it has the following main advantages of several important physical and chemical indicators:

1. To improve the strength of IGT picking.

2. To improve the whiteness of paper.

3. To improve the K & N ink absorption.

4. To improve the smoothness of paper.
