Embodiment 1

[0037] The embodiment is basically as figure 1 Shown: a kind of production method of continuous steel paper, comprises the following steps:

[0038] Step 1): Grinding and dispersing the finished plant fiber pulp by means of a pulverizer to loosen the plant fiber pulp.

[0039] Step 2): Send the loose plant fiber pulp to the zinc chloride solution spraying device, spray the zinc chloride solution, and carry out solid-liquid stirring for 20-40 minutes to carry out gelling treatment. In this embodiment, the stirring time is selected as 30min. In addition, the concentrated zinc chloride solution with a specific gravity of 1.91-1.98 is selected as the zinc chloride solution, and the concentrated zinc chloride solution with a specific gravity of 1.95 is selected in this embodiment.

[0040] Step 3): The gelatinized plant fibers are pulped and pressed by a pulp forming device to form continuous steel paper blanks, which are transported to the next process by paper guide rollers. S...

Embodiment 2

[0054] The differences between this embodiment and Embodiment 1 are:

[0055] The pulverizer adopted in the step 1), combined with figure 2 and image 3 As shown, two crushing rollers 1 rotating in the same direction are arranged inside, and lug plates 2 are arranged on the circumferential walls at both ends of each crushing roller 1. The axes of the rollers 1 are parallel, and the rotating shafts 3 are fixedly connected with crushing knives 4 , the crushing knives 4 on adjacent rotating shafts 3 are arranged alternately, and the crushing knives 4 on the two crushing rollers 1 are arranged alternately. A torsion spring 5 is arranged between the rotating shaft 3 and the ear plate 2 , one end of the torsion spring 5 is welded to the rotating shaft 3 , and the other end of the torsion spring 5 is welded to the ear plate 2 .

[0056] Both ends of the rotating shaft 3 are set through the ear plate 2, and the end of the rotating shaft 3 is welded with a baffle 6, which is paralle...

Abstract

The invention relates to the technical field of paper making and particularly discloses a method for producing continuous vulcanized fiber paper. The method comprises the following steps: (1) grindingplant fiber finished product pulp through a grinder to loosen the plant fiber pulp; (2) delivering the loosened plant fiber pulp into a zinc chloride solution spray device, performing zinc chloride solution spraying, and performing solid-liquid stirring for 20-40 minutes; (3) performing pulp spraying and press-molding to form a vulcanized fiber paper backing; (4) performing aging treatment; (5) performing desalination treatment; and (6) performing washing, drying and curling to form a vulcanized fiber paper finished product. The vulcanized fiber paper production method does not relate to material selection of body paper or gluing adhesion of multiple layers of the body paper, so that a vulcanized fiber paper produced by the method does not have the layering problem due to deficient adhesion of the body paper, and has high quality. Furthermore, an existing vulcanized fiber paper production method is overturned, the vulcanized fiber paper is produced directly from paper pulp, the process for producing body paper of vulcanized fiber paper is reduced, and the production flow of vulcanized fiber paper is shortened.

Description

technical field [0001] The invention relates to the technical field of papermaking, and specifically discloses a production method of continuous steel paper. Background technique [0002] Steel paper, a kind of processed paper with high hardness, has excellent elasticity, wear resistance, corrosion resistance, heat resistance, mechanical strength, insulation and mechanical processing and forming properties. At present, the production method of steel paper is usually to impregnate the base paper with a treatment agent (concentrated zinc chloride solution or copper ammonium solution) to make the cellulose swollen and gelled, and then bonded layer by layer on the gelling machine, and then aged and matured. Water immersion desalination, drying and shaping to make steel paper. It can be seen that the current steel paper is composed of multiple layers of base paper. After the production is over, there may be insufficient interlayer bonding inside the steel paper, resulting in del...
