When You Use The Forming Wire Did You Meet Problems?

The Influence of Resin on Forming Wire

1. Clean the forming wire;

-Low pressure steam can be used to remove resin spots on the metal mesh;

-For plastic wire, the vapor pressure should be below 3.5 kg/cm2 and the temperature should not exceed 1500C;

2. High pressure spray water is usually effective for resins;

3. Chemical treatment of the wire can reduce the tendency of resin aggregation;

4. Clean the forming wire with organic solvents.

How to Solve The Small Paper Scrapes Clog The Forming Wire

1. High flow on concentration will lead to:

-Slow water filtration;

-The vacuum degree of the vacuum suction box increases;

-The dryness of the paper entering the press section decreases;

-Increase the operating load of the paper machine;

-Felt wear accelerates.

2. Difficulty in peeling off the paper web will result in:

-A large amount of fibers penetrate into the forming wire and press felt;

-Stripping the paper web from the forming wire requires more energy;

-Increase wet traction force;

-More frequent decapitation;

-Paste the wire to increase the mesh marks.

3. Eliminate blocked forming wire:

-Minimize the dehydration of the breast roll;

-The paper material flow should be directly sprayed onto the leading edge of the forming board;

-The formed board should have no leading edge inclination angle;

-The front forming table should have a small inclination angle and a large arrangement space to control the initial dehydration rate.

4. Check whether the design of the forming wire is reasonable (whether the selection of the forming wire is reasonable);

The mesh surface in contact with the paper web should have a finer mesh, which is beneficial for reducing fiber penetration and the tendency to stick to the web.

5. Within the first 2 meters after passing through the weir plate, excessive dehydration will increase fiber penetration;

6.   If the sticking occurs at the forming plate, it may be due to pressure forming;

Ensure that the pulp speed is slightly lower than the mesh speed, so as to operate in a drag mode.
