Problems solved by technology

However, most of the pulp washing nets used in domestic pulp machines are products with less than two layers. With the increase of more than 300,000 tons of wide and high-speed pulp machines, the original commonly used products can no longer meet the use requirements in terms of pulp loss and service life.

Embodiment Construction

[0039] A production process for a multi-layer pulp washing net, comprising the following steps:

[0040] (1) Wire purchase

[0041] According to the requirements of the production plan, import high-quality monofilament from Germany according to the model, quality and quantity;

[0042] (2) Wire inspection

[0043] 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.

[0044] Warp: Ф0.45mm, tensile strength: 900N / mm 2 , heat shrinkage value: 14%;

[0045] Weft 1: Ф0.30mm, tensile strength: 600N / mm 2 , heat shrinkage value: 2%;

[0046] Weft 2: Φ0.25mm, tensile strength: 650N / mm 2 , heat shrinkage value: 10%;

[0047] Weft 3: Φ0.50mm, tensile strength: 500N / mm 2 , heat shrinkage value: 9%;

[0048] (3) Warping

[0049] The ten...

Abstract

The invention discloses a production process of a multi-layer pulp washing net. The production process includes the steps of filament purchasing, filament inspection, warping, healding, net weaving, net checking, primary shaping, net cutting, plugging connection, secondary shaping, finished product inspection, packaging and warehousing, and the like. A texture structure of 2.5 layers is adopted, and retention of pulp is guaranteed; the multi-layer pulp washing net is woven by 16 healds, long in bottom weft, large in floating length, wear-resistant and long in service life; the multi-layer pulp washing net is compact in net body structure, stable, regular and even in mesh, not easy to deform, capable of guaranteeing excellent dehydration and suitable for production and use of large-weight pulp boards and high-speed pulp machines.

Description

technical field [0001] The invention relates to a production process of a pulp washing net, in particular to a production process of a multi-layer pulp washing net. Background technique [0002] From the perspective of organizational structure development, polyester forming fabrics for papermaking have experienced single-layer fabrics, 1.5-layer fabrics, two-layer fabrics, 2.5-layer fabrics, and now widely used 3-layer fabrics. However, most of the pulp washing nets used in domestic pulp machines are products with less than two layers. With the increase of more than 300,000 tons of wide and high-speed pulp machines, the original commonly used products can no longer meet the use requirements in terms of pulp loss and service life. . In this regard, our company has successfully developed a perfectly unified 2.5-layer pulp washing wire with smooth and delicate papermaking surface and wear-resistant paper machine surface after many market researches. The network structure is t...
