We manufacture nozzles, atomizers, tank wash nozzles and spray pipes to help the paper industry with many recurring problems.There are various problems in paper mills. We analyzed five of these problems and provided solutions for HAPOO products for these five problems.

In the paper industry, water is one of the main ingredients:

In the initial stages of production, the solution consists of 95-97% water and 3-5% pulp and fibers. As a result, companies like HAPOO, which have been producing nozzles, atomizers, tank washers and sprinkler pipes for over 50 years, have specialized in this area and designed specialized products.

Nozzles, shower pipes, atomizers and tank wash nozzles produced by HAPOO play a key role in all stages of paper production. Applications for nozzles and other products are numerous: starch treatment, cleaning of filter felts and forming fabrics, washing, defoaming of feed boxes and refilling of paper, to name a few.

Foam generation during pulping:

The first process is to put the pulp into the pulper: this operation recovers the cellulose fibers, completely separates and hydrates them to form the actual pulp.
During this process, the surfactant and everything suspended in the water creates foam which we must eliminate before it overflows the tank.
Foam is removed by spraying water. For this kind of operation, HAPOO’s full cone nozzles are the ideal product.

The starch spray phase takes place in the absorption box area. The purpose of spraying starch is to compact the fibers of the stock, making the final product more durable.
The sprayed substance, commonly called starch, consists of chemical components such as corn, potato, and wheat flour. Since starch is a highly viscous solution, clogging of the spraying device may occur.
HAPOO offers its P-Series hollow cone nozzles to minimize this possibility.

After the slurry has been distributed onto the formed canvas, it is processed to remove as much moisture as possible. Among the various operations at this stage we find the paper refill. Needle jets generated by specific nozzles trim the edges of the stock to obtain the desired dimensions before the paper is transferred to the press. An imprecise and uneven cutting process at this stage results in a poor quality finished product.

Once out of the dry area, the paper goes to the rewinding phase: the material is wrapped on itself through a winder called “pope.”
In this phase, the speed of the rolling with the paper’s dryness and the material’s rubbing can generate electrostatic discharges, dangerous for the operators and the possible fires that could be developed.
To overcome this problem, it is advisable to install atomizers to spray water reduced to very tiny drops in the surrounding air, restoring the necessary balance of moisture that prevents the formation of electrostatic discharges.
