Embodiment 1

[0040] Embodiment one is basically as attached figure 2 and image 3 Shown:

[0041] A kind of manufacture technology of face paper in ground steel paper, comprises the steps:

[0042] Step 1, pulping: take cotton fibers, and pulp the cotton fibers to obtain a slurry with a beating concentration of 3% and a wet weight of 18-22g;

[0043] Step 2, increase the beating concentration: send the slurry that has passed step 1 into the thickening equipment, and the slurry flows through the upper and lower papermaking wires in the thickening equipment, and the pulp is dehydrated after being squeezed by the two papermaking wires. The beating concentration of the prepared slurry is raised to 5%;

[0044] Step 3, beating: Send the slurry that has completed step 3 into the screw propeller of the thickening equipment, and use the screw propeller to push the slurry with increased beating concentration into the disc refiner for beating treatment, and the obtained slurry beating degree is ...

specific Embodiment approach

[0051] In the prior art, the cotton fiber is subjected to low-concentration beating according to the production method of the prior art, that is, the slurry with a beating concentration of 3-3.2% is pumped into the disc refiner by a pulp pump for beating, and after the disc refiner is beaten The slurry is produced according to step 5 and step 6 in embodiment 1; compared with embodiment 1, the production method of the comparative example is that step 4 is lacking.

[0052] The beating concentration in Table 1 is the beating concentration of the pulp before entering the disc refiner, and the beating degree and wet weight are parameters after beating by the disc refiner.

[0053] The face paper produced in the prior art, the face paper produced in the comparative example and the face paper produced in Example 1 carry out the same test, and the breaking length, water absorption, air permeability, and tearing degree are all tests of the face paper obtained by production ; and the b...

Embodiment 2

[0062] Example two such as Figure 4 and Figure 5 As shown, on the basis of Embodiment 1, Embodiment 2 specifically refines the concentration equipment used in Step 2 of Embodiment 1.

[0063] The enrichment equipment includes material box 1, frame, traction group and screw propeller 2, material box 1, frame and screw propeller 2 are installed on the ground, and traction group is installed on the frame; partitions are welded in material box 1 3. The top of the material box 1 is closed, and there is a certain distance between the bottom of the partition 3 and the bottom of the material box 1. The partition 3 divides the material box into a pulp chamber 11 and a pulp discharge chamber 12, and the bottom of the material box 1 near the pulp chamber 11 An overflow pipe is installed, and a slurry outlet is provided on the right side wall of the slurry outlet chamber 12 of the material box 1 .

[0064] The traction group includes a first traction group 4 and a second traction grou...

Abstract

The invention relates to the technical field of vulcanized fiber paper, and particularly discloses a manufacturing process of facial tissue in abrasive vulcanized fiber paper. The manufacturing process comprises the following steps of taking cotton fibers, and pulping the cotton fibers to obtain pulp, wherein the pulping concentration is lower than 3.5 percent and the wet weight is 18-22 g; step two, improving pulping concentration: feeding the pulp obtained in the first step into concentration equipment, and dehydrating the pulp by passing through an upper papermaking mesh and a lower papermaking mesh in the concentration device to improve the pulping concentration of the prepared pulp to 4.5-5.5%; step three, pulping: feeding the pulp subjected to the third step into a spiral propeller of the concentration equipment, and pushing the pulp with the improved pulping concentration into a disc grinder by using the spiral propeller for pulping treatment to obtain pulp with the pulping degree of 40-45 DEG SR and the wet weight of 9-11 g; and step four, netting, dehydrating and drying to obtain the facial tissue. The scheme disclosed by the invention is used for solving the problems thatthe strength of the facial tissue produced by adopting the cotton pulp is low, the shrinkage is small, the elongation rate is low and the requirements on the strength and the elongation of the abrasive vulcanized fiber paper cannot be met in the prior art.

Description

technical field [0001] The invention relates to the technical field of steel paper, in particular to a production process of surface paper in ground steel paper. Background technique [0002] Steel paper base paper is mainly special paper made of plant fiber by paper machine. After layer-by-layer stacking and gelation reaction, steel paper base paper can be made into steel paper. The steel paper is hard and has excellent elasticity. Wear resistance, corrosion resistance, heat resistance, mechanical strength, insulation performance and machining formability, it is very easy to apply to various machining, such as cutting, drilling, bonding, punching and grinding. [0003] The steel paper used for grinding in the prior art (hereinafter collectively referred to as grinding steel paper) is divided into a surface layer and a sandwich layer according to the structure of the grinding steel paper. The steel paper base paper of the surface layer is also called a face paper, and the st...
