What is a high grade molded paper mesh 10

It is a polyester net formed in the wet part of papermaking, divided into warp and weft, with several layers, wear-resistant, pulp sprayed on the net, molding, dehydration, and entering the next step of pressing and dehydration.

This is a very general question!! It depends on what paper you do!! Nowadays, three-layer mesh is generally used!!

Paper machine forming web, i.e. sheet former1 – uses an endless web slurry suspension on which it is dewatered to form a web web, cardboard or pulp board. Forming mesh is a valuable equipment for papermaking, and there are two categories: metal mesh and plastic meshThe whole mesh is copper mesh and stainless steel mesh, mainly copper mesh.

Plastic mesh is mainly polyvinegar mesh, because of the advantages of corrosion resistance, wear resistance, long life and other advantages, the use of more and more The specifications and technical requirements of the forming mesh are distinguished by the width, length, weaving, mesh days and other meters. Generally, the thinner the paper, the more mesh is used.

There are many places where paper mesh is produced, and you are looking for a near waterfront because of transportation problems?

Papermaking network, Jiangsu, Shandong, Henan, Guangdong, Anhui Wuhu, Xi'an have factories.

Spiral press filter series products spiral press filter screen is the middle of the spiral mesh after adding filler to reduce the permeability, the mesh is dense, reduce the loss of material on the mesh, and the transverse stiffness of the mesh is large. It is mainly used for sludge dewatering, paper pulp washing, coal washing, chemical industry, wine bran dehydration, vinegar bran dehydration and other industries for filter pressing, and is better used for low air permeability parts on the drying parts of paper machines.

2725 is talking about the number of roots of the latitude and longitude lines, and the number of meshes is about 60 meshes, and the exact number has not been measured.

The identification of each ** business should be different, and the ** business should be asked for details.

The slurry is evenly sprayed on the rotating round net through the lip opening of the headbox and the initial dehydration begins, and the negative pressure generated in the net makes the pulp adhere smoothly to the net due to vacuum attraction and gravity, and accelerates the dehydration speed. The rotten net that rotates in the morning carries the preliminary dehydrated pulp into the slurry extrusion area in contact with the shuttlecock net, and continues to shed a large amount of water. The white water in the net is discharged from the white water discharge outlet at the lower part of the transmission side, and is squeezed by the shuttlecock net because the wet paper tire is sandwiched between the blanket nets.

Therefore, the fiber structure is relatively dense, and the spiral polyvinegar net is provided on the outside of the lower part of the blanket of the rotary screen to press the blanket to the mesh surface, so as to protect the formed wet paper tire from being broken by the white water that has not yet flowed out of the net, so that the shuttlecock net clamps the wet paper tire smoothly through the lower part of the rotary screen and turns upward to continue to dehydrate, and completes all the dehydration process of paper forming by pressure at the volcanic roller, forming a wet paper sheet. At this time, the shuttlecock is separated, and the rotary screen continues to accept the slurry from the headbox for dehydration and molding after being washed with high-pressure water, and the blanket holds the formed wet paper sheets, and then dehydrates them after vacuum dehydration and press dehydration. The blanket is returned after pressing, and the rollers such as tensioning, adjustment, and stretching pass through the bottom of the white water tray through washing and squeezing water, and then wrap around the forming roller to contact with the rotary screen and continue to clamp and form.

"Sirain" – an excellent retention and drainage aid for papermaking.

Under the current conditions, SIRAIN paper retention and drainage aids may be the ultimate choice for many paper manufacturers and distributors.

Why should you choose SIRAIN Papermaking Retention and Drainage Aids?

1 Usage and cost performance.

The economical use of sirain is about 400 grams per ton of pulp for the cultural packaging type.

This effect can only be achieved by two imported products, and their recommended dosage is 300 grams, but ** is 2-3 times that of sirain.

2 Viscosity of sirain.

In fact, the effect of papermaking retention and drainage aids, in many cases, is easy to determine, that is, according to the economic dosage of the merchant, after diluting 400 times, the viscosity is called the viscosity of use. In terms of retention, it is generally considered that the viscosity of 50 cPa when used after dilution is the qualified standard, 70 is good, 90 is excellent, if you pay attention to the measurement, you will find that the viscosity of Sirain after 400 times dilution is 90-110 cPa, which has almost no rival.

Sirain is very convenient to use in dilution, non-sticky cylinder, no ball, no paper disease, 20 minutes of thorough dilution, very convenient to use!

3 Stability of sirain.

When we talk about ionism, in fact, if the ionic monomer is not integrated into the molecular structure, good retention cannot be achieved. Sirain not only integrates ionic monomers into the molecular structure, but also has a unique unsaturated adsorption point. Therefore, its retention ability is multi-faceted, which is the guarantee of its excellent performance.

SIRAIN also attaches great importance to the reliability of raw materials in production, and at present, we always use first-class raw materials, and the elements used to improve quality are non-negotiable and irreplaceable.

At present, sirain has not had the problem of unstable quality since its application.

Choose Sirain! Because whether it is to increase production, improve quality, or save costs, SIRAIN will be the best choice for you.

It is the tension force of the forming mesh or pressing felt, and the principle of measuring the tension of the forming mesh with a tensiometer is very simple, and the pressure of the forming mesh on the tensiometer is measured.

kn m kNm The tension of the forming mesh is about up and down when working.

The paper produced by the long net is very different from the paper produced by the rotary screen, mainly in the physical indicators: 1The longitudinal and horizontal tension is different, the garden net is much larger, while the long net is smaller.

2.Depending on the expansion rate, the garden net is much larger, while the long net is smaller. 3.

In terms of printing, the paper produced by long net is more suitable for printing than the paper produced by garden net. And also.

In general, the paper produced by the long net is much better than the paper produced by the garden net.

Joint equipment for paper forging. It is mainly composed of netting, pressing and drying. There are two types of nets: round mesh and long net.

The press section is composed of press rollers and papermaking wool cloth. The dryer section consists of one or several dryers. Some long web machines are also equipped with mechanical calenders to improve the smoothness and tightness of the paper, among other things.

There are many types of paper machines, such as single-dryer paper machines (also known as Yankee paper machines) that manufacture single-sided glossy paper, long-net multi-dryer paper machines that manufacture general paper, tissue paper machines that manufacture typewriting paper and cigarette paper, and cardboard machines that manufacture cardboard. It generally refers to the machines that make all kinds of paper and cardboard, including dry paper machines and wet paper machines, and generally refers to wet paper machines. According to the structure of the forming part, there are three types: long net paper machine, rotary screen paper machine and clamp screen paper machine.

Their technical characteristics are often expressed in the form of their production capacity, paper grade, specification, vehicle speed and dryer section. Such as long net multi-cylinder paper machine, rotary screen double-cylinder paper machine, newsprint paper machine, cultural paper paper machine, cardboard paper machine, etc. The paper machine is a complex and large interconnected machine, including flowing, forming, pressing, drying, vacuum, white water and fiber**, water and steam supply, hot air and heat**, compressed air, lubrication and transmission systems.

Some paper machines are also equipped with embossing, wrinkling, sizing, coating, calendering, slitting and other mechanisms. Due to the different types of paper made, the configuration of various paper machines is not exactly the same. A machine used to make paper in the paper industry.

It is mainly composed of headbox, net section, pressing section, drying section, calendering section, and paper rolling section. There are many types, such as rotary screen paper machines, long screen paper machines, single-dryer paper machines that manufacture single-sided glossy paper, and sandwich paper machines with two webs.

If one side of the forming mesh is tight, the friction with the guide roller and the breast roller will be large, and the tightness of the forming mesh itself will also have a tensile force on the entire forming mesh, and the other side of the forming mesh will be looser, and the forming mesh will deviate to the side with pulling force. Adjust the deviation adjustment roller and tension roller should be easy to solve.
