Abstract
Disclosed are a production method for increasing skin-friction coefficient of kraft paper and a special device for the production method. The production method includes kraft paper production steps of shredding, pulping, shaping, pressing, drying, curling and splitting for packaging, and is mainly technically characterized in that a step of roll-coating, coating or spraying silica sol emulsion to the surface of the kraft paper is added between the drying step and the curling step. The special device is provided with a spray pipe with a plurality of nozzles. The spray pipe is connected with a pressure gauge, a lift pump, a vent valve and a filter through pipelines and is connected with a feeding barrel through a valve. A mixing motor is disposed on the feeding barrel. A reflow pipe is further connected to the other end of the spray pipe and is communicated with the feeding barrel through a valve. By the production method using the sprayed silica sol emulsion of special particle size to the surface of the kraft paper and taking advantage that silica sol forms glass beads on the surface of fiber, the skin-friction coefficient of the kraft paper is increased. The special device is even in spraying and effective.
Description
Technical field
The present invention relates to a kind of production method that increases the brown paper skin-friction coefficient and use its isolated plant.
Background technology
Skin-friction coefficient is compound key property with brown paper.Skin-friction coefficient hangs down sliding easily bag in transmission, handling process, causes production efficiency to descend.The regenerated fiber that particularly reclaims the milk box is short, and production process adds chemical agent, and the surface is more sliding relatively, and requires not to be inconsistent.
Summary of the invention
The present invention provides a kind of production method that increases the brown paper skin-friction coefficient to use its isolated plant.
The present invention realizes through following technical scheme: a kind of production method that increases the brown paper skin-friction coefficient; Comprise the brown paper production stage: pulping, slurrying, moulding, squeezing, drying, curl, cut packing, its major technique characteristic is to increase roller coating or coating in described drying and between curling or with the surperficial step of Ludox emulsion spraying brown paper;
Described Ludox particle diameter is 20 ~ 120 nanometers;
Described Ludox is the dispersion liquid of nano level silica in water or in the solvent, and the solubility weight ratio is 5 ~ 20%;
As preferably, described Ludox is the dispersion liquid of nano level silica in water or in the solvent, and the solubility weight ratio is 10%;
Described spraying position goes out between drying cylinder and the scanning support at paper;
The medicine spraying tube that said isolated plant is provided with some shower nozzles connects Pressure gauge, elevator pump, exhaust-valve, filter successively through pipeline, and even adds explosive barrel through valve, adds explosive barrel and is provided with stirring motor;
The said medicine spraying tube other end also connects return duct, and adds explosive barrel through the valve connection;
Said pipeline and return duct are communicated with the distilled water pipe blow-through respectively.
The present invention increases the method for brown paper skin-friction coefficient in brown paper is manufactured paper with pulp process, use specified particle diameter Ludox emulsion spraying brown paper surface, utilizes Ludox to form the characteristic of little bead at fiber surface, increases the coefficient of friction on brown paper surface.The spraying of this isolated plant is even, and effect is obvious.
Description of drawings:
Fig. 1 is the structural representation of isolated plant of the present invention.
The specific embodiment:
The production method of this increase brown paper skin-friction coefficient; Comprise the brown paper production stage: pulping, slurrying, moulding, squeezing, drying, curl, cut packing, promptly go out to increase between drying cylinder and the scanning support roller coating or coating or with the surperficial step of Ludox emulsion spraying brown paper in described drying and between curling at paper; The Ludox particle diameter of spray is 20 ~ 120 nanometers; Ludox is the dispersion liquid of nano level silica in water or in the solvent, and the solubility weight ratio is 10%.
As shown in Figure 1; The sprayer unit of this increase brown paper skin-friction coefficient is that the medicine spraying tube 2 that is provided with 10 shower nozzles connects Pressure gauge 3, elevator pump 4, exhaust-valve 5, filter 6 successively through pipeline; And connect through valve 7,8 and to add explosive barrel 9, add explosive barrel and be provided with stirring motor 10; The medicine spraying tube other end also connects return duct 11, and adds explosive barrel through valve 12 connections; Pipeline and return duct are communicated with distilled water pipe blow-through 13,14 respectively.
