Problems solved by technology

[0003] The quality of the baking base paper directly determines the quality of the baking paper. The baking base paper needs to have a high degree of tightness to reduce the penetration of the oil-repellent agent. Therefore, the beating degree of the pulp is generally high, which easily leads to uneven drying of the paper during drying. , the seersucker paper disease occurs, and then the amount of anti-oil agent increases during post-processing, and the cost increases. At the same time, the anti-oil agent is not evenly distributed, and the food and baking paper cannot be completely peeled off, which affects the aesthetics. In addition, excessive use of anti-oil agent also poses safety hazards. , degradation difficulties, environmental pollution and other issues
Europe and the United States started early on baking base paper manufacturing technology, but there are relatively few domestic researches on this

Embodiment 1

[0012] Choose 100% bleached coniferous wood pulp board, and enter the beating process after pulping and heavy slag removal. The beating is divided into two stages. After the first stage of beating, the beating degree of the pulp is controlled to 40°SR. The degree of beating is 65°SR, and the wet weight is 5.5g. After that, the slurry enters the high-level box, and 2.0% PAE relative to the dry pulp is added to the high-level box. After that, the slurry is diluted and heavy slag is removed. Add 0.7% cationic starch relative to absolute dry pulp and 0.05% defoamer relative to absolute dry pulp at the outlet of the pressure sieve. Pressing enters the first stage of drying process. The first stage of drying process includes 10 drying cylinders. The temperature of drying cylinders 1-4# is 80°C, the temperature of drying cylinders 5-9# is 86°C, and the temperature of drying cylinders 10# is 35°C, the first stage of calendering is carried out on the dried paper, the calendering temper...

Embodiment 2

[0016] Choose 100% bleached coniferous wood pulp board, and enter the beating process after pulping and heavy slag removal. The beating is divided into two stages. After the first stage of beating, the beating degree of the pulp is controlled to 40°SR. The degree of beating is 65°SR, and the wet weight is 5.5g. After that, the slurry enters the high-level box, and 3.0% PAE relative to the dry pulp is added to the high-level box. After that, the slurry is diluted and heavy slag is removed. Add 1.1% cationic starch relative to absolute dry pulp and 0.10% defoamer relative to absolute dry pulp at the outlet of the pressure sieve. Pressing enters the first stage of drying process. The first stage of drying process includes 10 drying cylinders. The temperature of drying cylinders 1-4# is 83°C, the temperature of drying cylinders 5-9# is 88°C, and the temperature of drying cylinders 10# is 40°C, the first stage of calendering is carried out on the dried paper, the calendering temper...

Embodiment 3

[0020]Choose 100% bleached coniferous wood pulp board, and enter the beating process after pulping and heavy slag removal. The beating is divided into two stages. After the first stage of beating, the beating degree of the pulp is controlled to 43°SR. The degree of beating is 68°SR, and the wet weight is 5.0g. After that, the slurry enters the high-level box, and 2.5% PAE relative to the dry pulp is added to the high-level box. After that, the slurry is diluted and heavy slag is removed. Add 1.1% cationic starch relative to absolute dry pulp and 0.10% defoamer relative to absolute dry pulp at the outlet of the pressure screen. Pressing enters the first stage of drying process. The first stage of drying process includes 10 drying cylinders. The temperature of drying cylinders 1-4# is 83°C, the temperature of drying cylinders 5-9# is 88°C, and the temperature of drying cylinders 10# is At 40°C, the first stage of calendering is carried out on the dried paper. The calendering tem...

Abstract

The invention discloses a production process of baking base paper. The baking base paper is prepared by adopting 100% bleached softwood pulp through pulping, heavy residue removal, beating, adding of a wet strength agent, dilution, heavy residue removal, screening, adding of an internal sizing agent and a defoaming agent, dilution, net loading, formation, squeezing, first-stage drying, first-stage calendering, second-stage drying, surface sizing, third-stage drying, second-stage calendering and taking-up. Due to adoption of a preparation process of three stages of drying, two stages of calendering and one stage of impregnated surface sizing, generation of seersucker paper defects is reduced, the paper is good in flatness, high in smoothness and large in tightness, a use quantity of an oil-proofing agent is easy to control, and the use quantity of the oil-proofing agent is reduced; meanwhile, the oil-proofing agent is uniformly distributed, and the problem of food residues in the process of stripping foods is reduced.

Description

technical field [0001] The invention belongs to the field of papermaking, and in particular relates to a production process of baking base paper. Background technique [0002] Baking paper is prepared by sizing or coating oil-repellent on the surface of baking base paper. It is used to isolate food such as bread and cakes during baking, and replaces part of baking tin foil (also called aluminum foil paper). It is low-cost and environmentally friendly. It was used earlier in foreign countries. With the improvement of material living standards in China in recent years, people's self-care awareness and environmental protection awareness have been continuously enhanced, and the demand for this paper has increased year by year. [0003] The quality of the baking base paper directly determines the quality of the baking paper. The baking base paper needs to have a high degree of tightness to reduce the penetration of the oil-repellent agent. Therefore, the beating degree of the pul...
