Embodiment 1
[0033] The pulping process of a kind of high-cleanliness primary color bamboo pulp of the present embodiment comprises the following steps:
[0034] Step a, transport the bamboo pulp to the pulp tower with softening liquid and fully soak and stretch for 24 hours, the amount of softening liquid is 20g / L to mix the pulp, then wash and dehydrate, separate the softening liquid, and obtain fully stretched pulp material;
[0035] The softening liquid is made by mixing the following raw materials in mass percentage:
[0038] Disodium edetate 0.15%
[0039] Sodium di-sec-octyl sulfonate maleate 1.2%
[0040] water balance.
[0041] Step b. The fully moistened pulp is first deslagged by a high-consistency slag remover, and then processed by a thickening device to make the concentration of the pulp reach 23%, and then transported to a high-consistency refiner for high-consistency beating, and at the same time, add a concentrat...

[0067] The softening liquid is made by mixing the following raw materials in mass percentage:
[0068] Sodium peroxide 18%
[0069] Sodium sulfite 3%
[0070] Disodium edetate 0.25%
[0071] Sodium di-sec-octyl sulfonate maleate 0.5%
[0072] water balance.
[0073] Step b. The fully moistened slurry is firstly deslagged by a high-consistency slag remover, and then processed by a thickening device to make the concentration of the slurry reach 25%, and then transported to a high-consistency refiner for high-consistency beating. At the same time, add a concentr...
