Embodiment 1

[0034] A kind of production method of heat-sealing self-adhesive type medical dialysis paper comprises the following steps:

[0035] Slurry disintegration: the silver star softwood pulp and star hardwood pulp with a ratio of 1:0.75 are mixed with sodium bicarbonate with a per ton pulp dosage of 3kg and a per ton pulp dosage of 2kg sodium carboxymethyl cellulose. Disintegrate in a disintegrator for 15 minutes, and finally add water to make a slurry with a concentration of 4.5%.

[0036] Beating: the process The slurry is made through a beating system with a knockout degree of 28 0 SR, a slurry with a wet weight of 6.5 g and a concentration of 4.2%.

[0037] Blending: the process Dilute the slurry with a concentration of 4.2% to a concentration of 3.5%, and mix it with additives evenly. The auxiliary agents include 1.8% of tapioca starch enhancer, 4.0% of wet strength agent, 1.8% of AKD sizing agent and 0.2% of peeling agent in the absolute dry slurry gelatinized at ...

Abstract

The invention discloses a production method of heat-sealing self-adhesive medical dialyzing paper. The production method comprises the following steps: pulping a pulp; pulping; preparing materials; forming on a net; squeezing and dehydrating; drying and surface sizing; drying, transferring and coating; calendaring and coiling; rewinding and packaging to obtain a finished product. According to themedical dialyzing paper prepared by the method, the indexes of air permeability and bonding strength can meet the use requirements of the medical industry, the production of base paper and an adhesivelayer is completed in a papermaking machine in one time, the medical dialyzing paper is directly used for manufacturing medical packaging paper plastic bags, the equipment, labor and transportation cost can be saved, and the efficiency is greatly improved.

Description

technical field [0001] The invention relates to a production method of heat-sealing self-adhesive medical dialysis paper, which belongs to the field of medical paper manufacturing. Background technique [0002] It has been more than 10 years since sterilization packaging was introduced to China, and disposable medical devices have replaced traditional glass medical devices. Many types of sterilization packaging have also appeared on the market, one of which is widely used is a paper-plastic bag package made of high-density polyethylene on one side and dialysis paper on the other: that is, the surface of the dialysis paper is gravure printed, Coating thermoplastic resin, or directly heat-sealing or glue-sealing with film materials such as high-density polyethylene, to make a paper-plastic packaging bag with dialysis function. Paper-plastic bags are favored by the medical industry and manufacturers because of their good antibacterial effect, long storage time, and convenient ...
