Paper Title:
The Research on Adjusting Color of Tinting Pigment and the Controlling of the Parameter
  Abstract

More and more case boards were used in our society. Shade adjusting plays an important part in case board manufacturing. Tinting pigment can replace dyes used in color adjusting of paper making. Tinting pigment has the advantages of less dosage, better coverage, better stability and also lower cost. In this article, the shortages of dye used in adjusting color and the present situation of tinting pigment used in adjusting color were introduced. The factors of beating degree of soft wood, the additives of AKD, contact time and PH to the tinting pigment adjusting color were investigated also. The results showed that the effect of color adjusting was best when the beating degree of wood soft was 44°SR. AKD was good to color adjusting of pigment in papermaking. The best contact time of red pigment and yellow pigment choose 6 minutes. The best contact time of orange pigment choose 4 minutes. With the increasing of PH, the value of a* and b* improved first and then declined. The red pigment reached the maximum value when the PH was 5.5, while the yellow pigment and orange pigment reached the maximum value when the PH was 6. So the best PH of red pigment was 5.5. The best PH of yellow pigment and orange pigment were 6.
