Decorative base paper production process and equipment utilizing diagonal stabilization technology

Abstract

The invention discloses a decorative base paper production process utilizing a diagonal stabilization technology. The process comprises the steps of repulping, pulping, pulp mixing, net part forming,squeezing, drying, surface sizing, secondary drying, calendaring, coiling, slitting, inspecting and warehousing. According to the decorative base paper production process and equipment utilizing a diagonal stabilizing technology, 5%-10% of nylon fibers are added, a beating degree is controlled between 35-degree SR and 40-degree SR, the expansion rate of the decorative base paper during transfer printing and dipping is ensured, the expansion rate and the elasticity of the whole piece of a decorative base paper during natural use are also ensured, the overall form of the decorative base paper can be ensured after the decorative base paper is used outdoors for a long time, and meanwhile, accumulation and extrusion of dehydrated paper pulp are effectively avoided, the uniformity of paper pulpmoisture in the process is guaranteed, the problems of poor smoothness and poor moisture of a finished body paper are effectively avoided, normal and efficient paper pulp dehydration can be effectively prevented from being influenced, meanwhile, auxiliary cleaning can be conducted on the interiors of a discharging roller and a discharging end, and great convenience is achieved.

Description

technical field [0001] The invention relates to the technical field of decorative base paper production, in particular to a decorative base paper production process and equipment utilizing diagonal stabilization technology. Background technique [0002] Decorative paper is an essential raw material in many building materials, such as low-pressure boards and high-pressure boards used in furniture and cabinets, as well as fireproof boards, floors, etc. Decorative paper requires a smooth surface, good absorption and adaptability, and a bottom The color requires uniform tone, and the color requires bright colors. When it is used, it is placed under the surface paper in the product structure, mainly to provide decorative patterns and cover the effect of preventing the bottom glue from seeping out, and this layer requires paper. Has good hiding power, impregnation and printing properties. [0003] However, when the existing decorative base paper is produced, the paper web is gene...

Problems solved by technology

[0003] However, when the existing decorative base paper is produced, the paper web is generally passed through the front dryer roll, and then introduced between the hard oil guide roll and the soft rubber roll paper by the front paper transfer roll before calendering, and the wet spraying device is sprayed on the paper web. water, and then introduce the rear dryer roller through the rear threading roller, that is, the diagonal stabilization technology, so as to avoid the phenomena of runaway and diagonal instability in the subsequent printing of the base paper, to ensure the quality of subsequent printing, and the production of the existing technology In the process, a large amount of wood pulp is used to ensure the liquid absorption performance of the decorative base paper, but considering the composite problem between the decorative base paper and the board, it is difficult to control the expansion rate of the paper during transfer printing and impregnation, and the paper web Before entering the semi-dry pressing area, the moisture content is relatively uneven. After semi-dry calendering, the paper web is prone to problems of poor smoothness and moisture.

[0004] At the same time, in the pulp pressing process of its decorative base paper production process, its pulp enters from one end of the pressing equipment, and is discharged from the other end of the pressing equipment after being dehydrated in the middle press. After the dehydrated pulp is discharged from the end of the pressing equipment, most They all fall naturally by gravity, but most of the dehydrated pulp is squeezed into blocks after being pressed, and its front and rear adhesion ability is strong, which makes its falling speed slow after being discharged from the end of the pressing equipment, and it is very easy to Accumulation and extrusion at the end of the press equipment will cause blockage, and the extrusion process of the accumulated and extruded pulp will cause uneven distribution of residual moisture in the interior, which further affects the subsequent semi-finished paper during semi-dry calendering. The uniformity of moisture will further seriously affect the problems of poor smoothness and moisture of the paper after calendering, and the accumulation of clogged dehydrated pulp will also seriously affect the normal and efficient pressing of pulp by the press equipment. In order to avoid this situation, If it happens, the operator needs to take special care of it and assist it in falling, which is very troublesome. For this reason, we propose a production process and equipment for decorative base paper using diagonal stabilization technology
