Embodiment

[0024] Embodiment: 1) the preparation of industrial solid waste slag fiber or waste chemical fiber pulp

[0025] First, cut the inorganic fiber or chemical fiber into short fibers with a length of 13-20 mm, use two-stage licker-in dry-type slag removal, loosen them into monofilament fibers with an opener, and wet-disintegrate them with a hydraulic disperser so that the fiber length is 3 ~ 10mm, the mass concentration is 0.5% ~ 15%, and after the mass concentration of the fiber slurry reaches 5% through the rotary screen thickener, add a softener with a mass of 0.03% of the fiber slurry to the fiber slurry, and then use a medium concentration Refining until the degree of beating is 40-45°SR; add water to dilute the pulp and send it to a high-frequency deflagger for deflaking. The mass concentration of the deflagrated pulp is 3%, and the water temperature is 50-60°C. In addition to coarse fiber, it is industrial solid waste slag fiber or waste chemical fiber pulp; the softener u...

Abstract

The invention relates to a preparation method for gas-phase rust preventive paper by using industrial solid waste fibers, the industrial solid waste is raw material, and is pressed, dehydrated, pre-dried, a wet web sheet is sprayed with a layer of efficient nontoxic vapor phase inhibitor, the wet web sheet is naturally shrunk in length and width by air floatation drying to make the wet web sheet high tensile and high intensity and toughness. A layer of moisture resistant agent is coated on the wet web sheet by wet coating head after air floatation drying, the moisture can be effectively obstructed, and then the rust preventive paper is softly rolled and curled in the after-drying section. The gas-phase rust preventive paper by using industrial solid waste fibers has the advantages of strengthening the material, improving the intensity of the rust preventive paper, high toughness, nontoxic, moisture proof, impact resistance and rust prevention.

Description

technical field [0001] The invention relates to a method for preparing gas phase antirust paper, in particular to a device and method for preparing gas phase antirust paper by using industrial solid waste fibers. Background technique [0002] At present, the vapor phase antirust paper widely used in China generally uses neutral kraft paper as the base paper, and coats the vapor phase antirust agent on its surface. Some first make crepe base paper, coat it with a layer of gas-phase corrosion inhibitor, and use another equipment to cover a layer of PE film on the other side. This kind of anti-rust paper can achieve a certain anti-rust effect, but its The strength cannot meet the needs and is easy to break. In the later development, a strengthening layer was added, which coated one side of the base paper with a corrosion inhibitor, the other side was covered with a layer of PE film, and a layer of woven cloth was covered on the PE film, so that the strength of the anti-rust pa...
