Problems solved by technology

The product is made by wet method. Although the quality is good, the equipment investment is large and the production cost is high.
At present, some domestic enterprises have also started the production of industrial wiping paper, but the product quality is poor, the wet strength is low, the absorption performance is poor, it is easy to leave hairy dust when using it, the paper is very hard, and sometimes it will scratch the surface of the wiped object
The invention patent application with application number 200610080430.4 discloses a manufacturing method of optical lens wiping paper. Environmental protection, so it is not suitable for the production of industrial wipes for the machinery manufacturing industry

Embodiment 1

[0011] A method for manufacturing industrial wiping paper, using natural wood pulp as raw material, using wet paper machine to make paper, and wrinkling by dry method, it is characterized in that: said wood pulp is made of long fibers with a fiber length of 2.4-2.6mm Wood pulp and short-fiber wood pulp with a fiber length of 0.75-1 mm are mixed, the weight ratio of the two is long-fiber wood pulp:short-fiber wood pulp=8:2, and the beating current is controlled at 320-360A. The online concentration of paper pulp is 0.05%. A wet strength agent is also added to the pulp, and the amount of the wet strength agent is 25kg per ton of paper. A dry strength agent CMC is also added to the pulp, and the dosage of the dry strength agent CMC is 1.5kg per ton of paper.

Embodiment 2

[0013] The invention adopts 100% virgin wood pulp, is matched with paper-making auxiliary agent, adopts wet method paper machine to carry out papermaking, and makes industrial wiping paper by dry method wrinkling. The wood pulp is composed of long-fiber wood pulp and short-fiber wood pulp. The long-fiber wood pulp is German Mason pulp, the fiber length is 2.4mm-2.6mm, the whiteness is ≥87% (ISO), and the dustiness is ≤10mm. 2 / 500g. The short fiber wood pulp is made of Indonesian KK pulp, the fiber length is 0.75mm-1mm, the whiteness is ≥85% (ISO), and the dustiness is ≤10mm 2 / 500g. The weight ratio of long-fiber wood pulp to short-fiber wood pulp is 8:2, and the beating current is controlled at 340±20A. If the beating of plant fiber is too high, the fibrillation of the pulp will be intensified, and there will be lint and powder loss during production, so the beating current should not be too high, and the fiber loosening should be the main method.

Embodiment 3

[0017] Proportion of fiber raw materials: long-fiber wood pulp with a fiber length of 2.4-2.6mm and short-fiber wood pulp with a fiber length of 0.75-1mm are mixed, and the weight ratio of the two is long-fiber wood pulp:short-fiber wood pulp= 8:2;

[0018] The wet strength agent adopts PAE papermaking wet strength agent, and the dosage is 40kg per ton of paper;

[0019] The dry strength agent adopts CMC (carboxymethyl cellulose), and the dosage is 1.5kg per ton of paper;

[0020] The long-fiber wood pulp and short-fiber wood pulp are mixed and crushed, the beating current is controlled at 340±20A, and the paper is made with a crescent paper machine, the concentration of the net: 0.05%, the speed: 1000m / min, after drying, wrinkling, suction, After softening, coiling, slitting and packaging, the finished product is made.

[0021] The production process is shown in Figure 1.

Abstract

The present invention discloses a manufacturing method of industrial wiping papers, the method uses wood pulp as raw material and makes paper by wet paper machine and prepares products through dry method wrinkling. Said wood pulp is mixed and composed of long fiber pulp which fiber length is 2. 4-2. 6 mm and short fiber pulp which fiber length is 0. 75-1 mm, the weight ratio of the both is long fiber pulp: short fiber pulp = 8:2, the beating current is 320-360A. The invention has small equipment investment, the production cost is low, the prepared industrial wiping paper fiber bonded finely and closely, and has good imbibition performance and deoiling capacity, especially it is suitable for machinery industry such as automobile.

Description

technical field [0001] The invention relates to a method for manufacturing paper, in particular to a method for manufacturing industrial wiping paper. Background technique [0002] In recent years, with the rapid development of the automobile manufacturing industry, industrial wiping paper has been rapidly promoted and applied in the machinery manufacturing industry. This product is mainly used for wiping or experimenting with oil, water and other liquids such as mechanical equipment, products, molds, instruments, tools, etc. Room and other dust cleaning. Industrial wiping paper should have the following properties: the paper is delicate and soft, has sufficiently high dry and wet strength, is dust-free, has good absorption performance, is environmentally friendly, and can be recycled or burned without producing toxic substances. The industrial wiping paper used in China is mainly imported, and most of them are manufactured by Kimberly-Clark. The product is made by wet met...
