Problems solved by technology

The medical crepe paper currently on the market usually uses wood pulp as the main component. Due to the short wood pulp fibers and high content of non-cellulose components, the medical crepe paper made generally has high tightness, poor air permeability, low strength, and elongation. Poor rate and other disadvantages

Embodiment 1

[0021] After pulping 60% of cotton pulp and 40% of coniferous wood pulp, mix and beat, so that the beating degree reaches 22°SR, and the wet weight is 10g; add PPE wet strength agent, the amount of wet strength agent accounts for 1.5% of the total pulp , after refining and homogenizing, use an inclined wire paper machine to make paper, and the concentration of the slurry on the net is 0.35%; then the wet scraper is wrinkled, and the angle between the wrinkling scraper and the tangent line of the cylinder surface is 30°, and the scraper is placed on the surface of the cylinder The blade angle is 75°; it is dried in a drying cylinder, and then cut and packaged to obtain the finished medical crepe paper base paper.

Embodiment 2

[0023] After pulping 55% of cotton pulp and 45% of coniferous wood pulp, mix and beat, so that the degree of beating reaches 23°SR, and the wet weight is 11g; add PPE wet strength agent, the amount of wet strength agent accounts for 1.8% of the total pulp , after refining and homogenizing, use an inclined wire paper machine to make paper, and the concentration of the slurry on the net is 0.35%; then the wet scraper is wrinkled, and the angle between the wrinkling scraper and the tangent line of the cylinder surface is 32°, and the scraper is placed on the surface of the cylinder The blade angle is 80°; it is dried in a drying cylinder, then cut and packaged to obtain the finished medical crepe paper base paper.

Embodiment 3

[0025] After pulping 50% of cotton pulp and 50% of coniferous wood pulp, mix and beat, so that the degree of beating reaches 24°SR, and the wet weight is 12g; add PPE wet strength agent, the amount of wet strength agent accounts for 2% of the total amount of pulp , after refining and homogenizing, use an inclined wire paper machine to make paper, and the concentration of the slurry on the net is 0.35%; then the wet scraper is wrinkled, and the angle between the wrinkling scraper and the tangent line of the cylinder surface is 35°, and the scraper is placed on the surface of the cylinder The blade angle is 78°; it is dried in a drying cylinder, and then cut and packaged to obtain the finished medical crepe paper base paper.

Abstract

The invention belongs to the technical field of special paper manufacturing, and particularly relates to medical crepe paper body paper which is used for protecting a sterilization instrument to carry out sterile storage or conveying in a sterile state. The medical crepe paper body paper is characterized in that cotton pulp and needle-point leaf wood pulp are used as fibrous materials, and a traditional papermaking technology is used for manufacturing the body paper, namely beating, rinsing, pulp rectifying, papermaking, slitting and packaging. The cotton pulp is used as the main raw material, the needle-point leaf wood pulp is used as the auxiliary raw material, the characteristics that cotton fibers are tough in property, fine and smooth and soft in texture, good in folding resistance and abrasion resistance and absorption performance are used, and therefore produced paper is fine and soft and good in smoothness. Polyphenylene oxide polyphenyl ether (PPE) wet strength agents are added in pulp, and the strength, the stiffness, the smoothness and the water resistance of the crepe paper body paper are further improved. The medical crepe paper body paper is soft in hand feel, good in air permeability, high in strength, high in tensile strength, good in smoothness and good in water resistance.

Description

technical field [0001] The invention belongs to the technical field of special paper production, and in particular relates to a medical crepe paper base paper used to protect sterilized equipment for aseptic storage or delivery in a sterile state. Background technique [0002] Medical crepe wrapping paper can make steam and other media permeate into the packaging, effectively kill bacteria and other microorganisms and effectively block microorganisms, and can ensure that the sterilized sterile instruments are delivered in a sterile state or stored for a long time without Infected. The medical crepe paper currently on the market usually uses wood pulp as the main component. Due to the short wood pulp fibers and high content of non-cellulose components, the medical crepe paper made generally has high tightness, poor air permeability, low strength, and elongation. Disadvantages such as poor rate. Contents of the invention [0003] The technical problem to be solved by the p...
