Embodiment 1
[0037] (1) Bleached coniferous pulp and bleached hardwood pulp are added to a pulper equipped with 40°C pulping water at a mass ratio of 1:4 to fully crush them, and when the water temperature drops to 28°C while pulping, add pulp Black pigment (Diresul Black RDT-KAS.CN Liq) with a mass of 25% of the raw material; after reducing the beating degree of the bleached wood pulp to 32°SR, and the mass concentration reaches 4%, pump it into the crushing tank for standby.
[0038] (2) Dilute the kaolin, which accounts for 15% of the mass of the slurry, to a mass concentration of 70%, fully stir it with a high-speed agitator, and then put it into the above-mentioned crushing tank. After mixing and stirring evenly, adjust the pH value of the slurry in the pulping tank to 9.
[0039] (3) Pump the slurry in the crushing tank into the filling tank, adjust the pH value of the slurry in the filling tank to 7, add a coloring agent accounting for 1.5‰ of the slurry mass in the slurry, stir well...
Embodiment 2
[0046] (1) Bleached coniferous pulp and bleached hardwood pulp are added to a pulper equipped with clear water for pulping at 40°C according to the mass ratio of 1:4.2, and fully crushed. At the same time, add pulp when the water temperature drops to 27°C The black pigment of 26% of material quality; after reducing the percussion degree of bleached wood pulp to 32 ° SR, and the mass concentration reaches 4%, it is pumped into the pulping tank for standby.
[0047] (2) Dilute the kaolin that accounts for 13% of the mass of the slurry to a mass concentration of 68%, fully stir it with a high-speed agitator, and then put it into the above-mentioned crushing tank, and adjust the pH value of the slurry in the pulping tank to 9 after mixing and stirring evenly .
[0048] (3) Pump the slurry in the crushing tank into the filling tank, adjust the pH value of the slurry in the filling tank to 7, add a colorant accounting for 1~2‰ of the slurry mass in the slurry, stir well and then add...
Embodiment 3
[0055] (1) Bleached coniferous pulp and bleached broad-leaved pulp are added to a pulper equipped with clear water for pulping at 42°C at a mass ratio of 1:3.8 and fully crushed. At the same time as pulping, add pulp when the water temperature drops to 28°C Black pigment with 30% mass of raw material; reduce the degree of percussion of bleached wood pulp to 32°SR, and pump it into the pulping tank after the mass concentration reaches 4%.
[0056] (2) Dilute kaolin, which accounts for 17% of the mass of the slurry, to a mass concentration of 71%, fully stir it with a high-speed agitator, and then put it into the above-mentioned crushing tank. After mixing and stirring evenly, adjust the pH value in the pulping tank to 9.
[0057] (3) Pump the slurry in the crushing tank into the filling tank, adjust the pH value in the filling tank to 7, add a coloring agent accounting for 1.8‰ of the slurry quality into the slurry, stir evenly, and then add 125‰ of the slurry quality. Strength...
