Embodiment Construction

[0006] Put 90% coniferous wood pulp and 10% hot-melt fiber into the pulper to mix and decompose. The performance indicators of coniferous wood pulp are: 87.16% cellulose, 8.18% pentose sugar, 0.3 copper price, 89.8% whiteness, fiber The average length is 2.42mm, the hot-melt fiber is polyvinyl alcohol fiber, and its performance indicators are: thickness 1.1dt, length 3mm, melting point 60°C, polymerization degree 1313-1463. The coniferous wood pulp and hot-melt fiber are fully thawed and then pumped to the raw pulp bin, then sent to the mixing bin after being beaten by a double disc mill, and then pumped to the front bin for storage. The pulp is sent from the front bin to the pulp stabilization bin, and 0.5% of the reinforcing agent of the total weight of the pulp is continuously added into the pulp stabilization bin. The enhancer is cationic polysaccharose, its viscosity is 1000mpas, its water content is less than or equal to 13%, and it is in powder form. After the slurry i...

Abstract

The preparation method of base paper, it is used to produce medical moisture absorption paper tip. The 85-95% softwood pulp and 5-15% hot melt fibre are mixed and put into the pulp kneader to thiolysis, and then pumping them into primary pulp barn, sending them to mixture barn after duplex beating, then we can get the pulp, and adding intensifier the weight of which is 0.5 percent of the pulp. Delivering the pulp into header box after the pulp passes through the scummer, and continuously adding the dispersant agent the weight of which is 0.5 percent of pulp into the header box. Then the pulp gets into the net box, netting, and the pulp can form the wet paper after the pulp is molded and dehydrated in the net box. The wet paper dehydrates greatly in the pressing part, and then it is dried in the drying part. The paper tip can get through batching, rewinding and splitting. The base paper which is used to produce medical moisture absorption paper tip has the merits such as higher strength of extension, better softness and higher smoothness, and it is not easy to drop fur, the cost of it is low.

Description

technical field [0001] This invention relates to paper, and more particularly to medical paper having liquid absorbent properties. Background technique [0002] At present, in stomatological hospitals, hygroscopic paper tips are used instead of cotton swabs to absorb the liquid in the tooth cavity and dip in the medicine, which is sterile, has a large amount of liquid absorption and fast liquid absorption speed, and has a smooth shape and is easy to enter the root canal. It does not swell after absorbing moisture. However, the existing base papers that can be used to make moisture-absorbing paper tips still have the disadvantages of low tensile strength, poor softness, low smoothness, easy to shed sometimes and high production costs. . Contents of the invention [0003] The purpose of the present invention is to provide a method for manufacturing medical moisture-absorbing paper tip base paper with high tensile strength, good softness, high smoothness, no lint loss and lo...
