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.
