Abstract
The invention relates to papermaking equipment, in particular to a structure of a forming wire in the papermaking equipment. The papermaking forming wire is characterized in that a plurality of cotton warps and a plurality of cotton wefts are woven into a flaky wire belt by means of plain weaving, the running direction of the warps is not perpendicular or parallel to that of the wefts when the warps and the wefts are used on a paper maker, the flaky wire belt is changed into an endless annular wire belt by means of an end connecting procedure, and the formed endless annular cotton wire belt is soaked into polyurethane solution and dried to form the papermaking forming wire covered with a polyurethane coating layer. The papermaking forming wire is used for papermaking in the papermaking equipment.
Description
Technical field
The present invention relates to paper making equipment, relate in particular to the structure of the forming web in the paper making equipment.
Background technology
Paper mill is the process that realizes paper pulp is become paper through a series of equipment and operation now.Wherein the fourdrinier forming drying machine is wherein topmost equipment.In paper-making process, paper pulp is transported to head box, and is ejected on the moulding wire side through head box; Forming web is a kind of annular guipure for no reason that forms of weaving; Forming web at breast roll, couch roll, drive between a plurality of deflector rolls such as net roller, wite roll with the certain speed round and round, the various dewater units on the forming table are positioned at the downside of forming web contact bottom layer, such as suction box, Wiper blade; Paper pulp is injected into the one-tenth paper layer of moulding guipure; In the guipure running, the moisture in the paper pulp and other liquid are filtered, and the raw fiber in the paper pulp is separated from aqueous medium; One-tenth paper layer at forming web forms wet web, and after suction couch roll, gets into pressed zone through transfer device.Wet web leaves the back, district that is shaped and gets into pressed zone; In pressed zone press felt is arranged; Press felt is between one or more groups pressure roller; With the certain speed round and round, remove redundant moisture in the wet web from the pressure of pressure roller, and strengthen removal ability redundant moisture in the wet web through press felt.Wet web is transported to dry section through after the pressed zone, further removes the moisture in the paper web at dry section, with processing and the packing instructions that reach later process.
The weaving method of existing papermaking forming web is a kind of to be that yarn through the traffic direction of the woven warp of flat weaving method when on paper machine, using is consistent; The sheet guipure of the vertical traffic direction of parallel when on paper machine, using; The joint operation of generally knowing through the industry again becomes the sheet guipure into the endless guipure.Another kind method is directly to be woven into continuous endless guipure through weaving method for no reason; The yarn of the vertical traffic direction when weaving the warp of usefulness and on paper machine, using is consistent, and the yarn of the traffic direction when weaving the parallel of usefulness and on paper machine, using is consistent.
The weak point of the existence of existing papermaking forming web is: 1. the warp of forming web, parallel are vertically to weave; The mesh that forms also is a square or rectangular; Vertically disposed with the traffic direction of paper machine; Cause paper pulp inhomogeneous like this, adhere to morely, and make the paper of producing vertically inconsistent with horizontal tension degree at the warp of the forming web fiber that makes progress at last network process.2. the joint of first kind of weaving method can't be smooth fully, and influence is used; Second kind of weaving method cost is higher.3. the ABRASION RESISTANCE of forming web is not high, needs to change forming web after use a period of time.
Summary of the invention
Therefore, the present invention is directed to the weak point of the existence of existing papermaking forming web, propose a kind of improved papermaking forming web.This improved papermaking forming web can avoid the paper pulp online uneven, and non junction and cost are low, and ABRASION RESISTANCE is higher.
Technical scheme of the present invention is:
A kind of papermaking forming web, this papermaking forming web are to weave with complex root cotton warp and cotton parallel flat weaving method to form the sheet guipure, and warp the traffic direction during with use on paper machine is not perpendicular or parallel with parallel; Utilize the joint operation again, the sheet guipure is become the endless guipure; The endless cotton guipure that forms is immersed polyurethane solutions, and oven dry forms the papermaking forming web that is coated with the polyurethane clad.
Further preferred, described warp and parallel and on paper machine the traffic direction during use all be 45 °.
Further preferred; Described sheet guipure is to weave the second cotton warp and the second cotton parallel through interting on the basis of original again cotton warp of compound flat weaving method hatching and cotton parallel; The traffic direction of second warp when on paper machine, using is consistent, and the traffic direction of second parallel during with use on paper machine is vertical.
The present invention adopts as above technical scheme, and the technological merit that has is:
(1) warp of papermaking forming web and the parallel traffic direction when on paper machine, using is not perpendicular or parallel, can avoid the paper pulp online uneven, prevents the laterally vertical defective that differs of pull resistance of paper.
(2) the endless guipure is to weave formation sheet guipure through flat weaving method to utilize the joint operation to form again; It is lower that cost relatively directly is woven into continuous endless guipure through weaving method for no reason; And joint is owing to coat through immersing polyurethane (PU) solution; Therefore joint is smooth, can not influence use.
(3) coat owing on the basis of endless cotton net, immersing polyurethane solutions, polyurethane (PU) has better ABRASION RESISTANCE, has strengthened the ABRASION RESISTANCE of papermaking forming web greatly, so longer service life.
The specific embodiment
Combine the specific embodiment that the present invention is further specified at present.
Embodiment 1:
The papermaking forming web of this embodiment is to weave with complex root cotton warp and cotton parallel flat weaving method to form the sheet guipure, and warp and parallel and on paper machine the traffic direction during use all be 30 ° (forming the mesh of rhombus); Utilize the joint operation again, the sheet guipure is become the endless guipure; The endless cotton guipure that forms is immersed polyurethane solutions, and oven dry forms the papermaking forming web that is coated with the polyurethane clad.
Embodiment 2:
The papermaking forming web of this embodiment is to weave with complex root cotton warp and cotton parallel flat weaving method to form the sheet guipure, and warp and parallel and on paper machine the traffic direction during use be to be 45 °; Utilize the joint operation again, the sheet guipure is become the endless guipure; The endless cotton guipure that forms is immersed polyurethane solutions, and oven dry forms the papermaking forming web that is coated with the polyurethane clad.
Embodiment 3:
The papermaking forming web of this embodiment is to weave with complex root cotton warp and cotton parallel flat weaving method to form the sheet guipure, and warp the traffic direction during with use on paper machine is not perpendicular or parallel with parallel; On the basis of original cotton warp and cotton parallel, intert then and weave the second cotton warp and the second cotton parallel; The traffic direction of second warp when on paper machine, using is consistent, and the traffic direction of second parallel during with use on paper machine is vertical; Utilize the joint operation again, the sheet guipure is become the endless guipure; The endless cotton guipure that forms is immersed polyurethane solutions, and oven dry forms the papermaking forming web that is coated with the polyurethane clad.
