The general quality of toilet paper is made of wood, which is closely related to everyone's life in our daily life. Toilet paper processing technological process is: raw material crushing, coarse grinding, cooking and heating, double disk pulping machine, vibrating screen, pulp, pulp pump, rinse well and bleaching, centrifugal screen, mixer, slurry pump, the papermaking host - rewinding machine, punch, embossing, paper cutter, packaging, sales
1. The role of dispersant and softener should not ignore the addition of appropriate dispersants in the online slurry, which can obviously improve the evenness of the paper pages to improve the softness and feel of the paper pages. At present, most domestic manufacturers adopt imported peo-wf or domestic PEO as dispersant. When using PEO, pay attention to the selection of molecular weight, preparation method (composition concentration and dissolution rate), and control of adding quantity (general 1). 0 to 1. 5kg/t paper) and the impact of water quality.
2. The correct wrinkling process is the key to the copying of the high grade toilet paper. The wrinkling is the peeling of the paper on the surface of the dryer, while the paper is slightly crimped and wrinkles.
3. Suitable length and short fiber ratio is the precondition for the copy of soft toilet paper. Long fiber pulp can give toilet paper sufficient strength, while the short fiber pulp will have more influence on the opponent's feeling, especially the softness.
4, a good beating process is the production of soft tissue guarantee for toilet paper manufacture paper with pulp, because based on fiber length different pulp as raw material, so we must strictly control the beating process. In general, long fiber pulp must pass a beating, sufficient strength to give of toilet paper, the beating degree can be controlled in 30 ~ 45 "SR, and short fiber or waste pulp is mainly relief, along with mild cut off, the beating degree can be controlled in 20 ~ 30" SR. The slurry degree of web slurry is generally controlled at 28 ~ 40.
