Problems solved by technology

[0002] Since the weight of the pulp board is generally greater than 500g / m 2 , dense and thick, difficult to dehydrate, making it difficult to increase the speed of the pulp machine
At present, low-speed pulp machines are still widely used in China, and most of the pulp nets used are single-layer products, but there are problems such as large fiber loss, easy deformation of the mesh, insufficient strength, and short service life.

Embodiment Construction

[0037] A production process for improving the pulp-making net, comprising the following steps:

[0038] (1) Wire purchase

[0039] According to the requirements of the production plan, import high-quality monofilament from Germany according to the model, quality and quantity;

[0040] (2) Wire inspection

[0041] According to the requirements of the production plan, the wire diameter, heat shrinkage, tensile strength, acid and alkali resistance and other indicators are inspected one by one. According to the specific production requirements, random inspections and full inspections are carried out in batches.

[0042] Warp: Ф0.80mm, tensile strength: 600N / mm 2 , heat shrinkage value: 10%;

[0043] Weft: Φ0.80mm, tensile strength: 550N / mm 2 , heat shrinkage value: 3%;

[0044] (3) warping

[0045] The tension of each monofilament is required to be uniform, warping speed: 30m / min, tension: 80kg / ring;

[0046] (4) delivery head

[0047] According to the fabric dra...

Abstract

The invention discloses a process for manufacturing an improved pulp net. The process includes steps of thread purchasing, thread inspection, warping, drafting, net weaving, net inspection, primary setting, net cutting, splicing, secondary setting, finished product inspection, packaging, warehousing and the like. The process has the advantages that owing to scientific and reasonable thread diameters and densities of warps and wefts and the process for weaving and manufacturing the improved pulp net by the aid of proper tension, a net of the improved pulp net is compact and stable in structure, meshes of the improved pulp net are regular and uniform, the improved pulp net is not easy to deform, excellent dehydration is guaranteed, and the process is applicable to low-speed pulp machine for manufacturing heavy-weight pulp boards.

Description

technical field [0001] The invention relates to an improved production process of a pulp-making net. Background technique [0002] Since the weight of the pulp board is generally greater than 500g / m 2 , dense and thick, and difficult to dehydrate, making it difficult to increase the speed of the pulp machine. At present, low-speed pulp machines are still widely used in China, and most of the pulp nets used are single-layer products, but there are problems such as large fiber loss, easy deformation of the mesh, insufficient strength and short life. After several tests, our company has improved the single-layer pulp wire, and achieved remarkable results in the evenness of the pulp board, prevention of fiber loss, dehydration, and service life after being used on the paper machine. Contents of the invention [0003] The purpose of the present invention is to provide an improved production process of the pulp washing wire to prevent fiber loss and improve the life of the pul...
