Problems solved by technology

[0002] At present, drinking straws on the market are widely made of plastics. Because plastics are extremely difficult to degrade naturally, causing serious environmental pollution, some developed countries have restricted the use of some plastic straws.
Foreign beverage straws have widely used paper straws to replace plastic straws. The technology of paper straw paper and straw processing equipment has matured. Domestic straw paper processing equipment has been introduced, and straw paper is still in the research and development stage.

Embodiment 1

[0022] Example 1: 120 grams of straw paper

[0023] First use a pulper to pulp bleached kraft softwood pulp and bleached kraft hardwood pulp respectively, and then beat to 46°SR and 37°SR respectively, with a beating concentration of 3.0%, and bleach kraft needles at 40%. Leaf wood pulp and 60% bleached kraft hardwood pulp are mixed to obtain pulp, and the pulp is pumped from the pulping tank to the high level box, and then 0.5% of AKD glue and 4.0% of wet strength agent are added in the auxiliary materials, and the punching Slurry pump pumps it into the slag remover, after the slag is removed, it is sent to the pressure screen, and CMC0.40% is added to the inlet of the pressure screen; then the mixed slurry is transported to the stabilization box, and 6% light calcium + heavy calcium is added to mix After uniformity, it is sent to the headbox. The opening of the lip of the headbox is 13.0mm. Double-sided dehydration is carried out by overlapping the net to ensure that the fib...

Embodiment 2

[0025] Example 2: 120 grams of straw paper

[0026] First use a pulper to pulp bleached kraft softwood pulp and bleached kraft hardwood pulp respectively, and then beat to 43°SR and 36°SR respectively, with a beating concentration of 4.0%, and bleach kraft needles at 43%. Leaf pulp and 57% bleached kraft hardwood pulp were blended to obtain pulp, and the pulp was pumped from the pulping tank to the high-level box, and then 0.8% of AKD glue and 3.0% of wet strength agent were added in the auxiliary materials, and the punching Slurry pump pumps it into the slag remover, after removing the slag, it is sent to the pressure screen, and CMC0.36% is added to the inlet of the pressure screen; then the mixed slurry is transported to the stabilization box, and 6% light calcium + heavy calcium is added to mix After uniformity, it is sent into the headbox. The opening of the lip of the headbox is 12.0mm. Double-sided dehydration is carried out by overlapping the net to ensure that the fib...

Embodiment 3

[0028] Example 3: 120 grams of straw paper

[0029]First use a pulper to pulp bleached kraft softwood pulp and bleached kraft hardwood pulp respectively, and then beat to 47°SR and 33°SR respectively, with a beating concentration of 3.5%, and bleach kraft needles at 45%. Leaf pulp and 55% bleached kraft hardwood pulp are mixed to obtain pulp, and the pulp is pumped from the pulping tank to the high level box, and then 1.0% of AKD glue and 3.5% of wet strength agent are added in the auxiliary materials. Slurry pump pumps it into the slag remover, after the slag is removed, it is sent to the pressure sieve, and CMC0.35% is added to the pressure sieve inlet; then the mixed slurry is transported to the stabilization box, and 6% light calcium + heavy calcium is added After mixing evenly, send it to the headbox. The opening of the lip of the headbox is 12.8mm. Double-sided dehydration is carried out by overlapping the net to ensure that the fibers are evenly dispersed, and the verti...

Abstract

The invention discloses a manufacturing method of a beverage drinking straw paper. The method comprises the technical processes of pulp beating, pulp blending, additive adding, wet paper making, pre-drying, surface sizing, after-drying, calendaring and rolling. The beverage drinking straw paper belongs to papers for foods and meets the sanitary requirements on the papers for foods. The beverage drinking straw paper is manufactured by choosing preferable raw and additive materials and chemicals and taking chlorine-free bleached softwood kraft paper pulp and chlorine-free bleached hardwood kraftpaper pulp as fiber raw materials, which contain no toxic chemical substances such as organic chlorides and are environmentally friendly, sanitary and free from damage to human body. The produced beverage drinking straw paper is high in dry strength and wet strength, free from breakage, high in humidity resistance and capable of being rapidly decomposed to meet the environmental requirements as we as the sanitary requirements on the papers for foods.

Description

technical field [0001] The invention belongs to papermaking technology, in particular to a method for manufacturing drinking straw paper. Background technique [0002] At present, drinking straws on the market are widely made of plastics. Because plastics are extremely difficult to degrade naturally, causing serious environmental pollution, some developed countries have restricted the use of some plastic straws. Foreign beverage straws have widely used paper straws to replace plastic straws. The technology of paper straw paper and straw processing equipment has matured. China has introduced straw paper processing equipment, and straw paper is still in the research and development stage. For this reason, developing straw paper to reduce white pollution is not only the trend of the times, but also a good thing for the country and the people. [0003] Straw paper products are required to meet the hygienic requirements of food paper, high dry and wet strength, good moisture res...
