The function of the environmental protection paper machine forming device, also known as the wire part, is an important part of the paper machine. The paper suspension forms the paper sheet on it. The quality of the paper and the normal production of the paper machine are all related to the operatio
The multi-layer slanted mesh former distributes pulp in multiple central pulpers and sizing in layers in the headbox. It adopts unique rectification and layering technology to realize the layered forming of fibers in the forming area, which can achieve two-layer, Three or more coats of sizing. In the production of slanted nets, the on-site control of the quality of papermaking and the process parameters of normal operation should be carried out.
Pulping is to separate the fibers from the raw materials of trees, make fiber pulp, and then bleach; papermaking is to dilute the fiber pulp, shape, press, dry, and then make paper. Both processes discharge large amounts of wastewater. The wastewater produced by pulping is seriously polluted. The pollutant concentration in the wastewater discharged during pulp washing is very high, the BOD is as high as 10-36g/L, and it contains a lot of plant fibers, inorganic salts and pigments. The wastewater discharged from the bleaching process also contains a large amount of acid and alkali substances. The wastewater discharged from the paper machine contains a large amount of fibers and fillers and sizing materials added during the production process.
The calender is mainly composed of printed matter conveying mechanism, mechanical transmission, electrical control system and other parts, including printed matter conveying table, manual high pressure oil pump, hot pressing roller, pressure roller, speed regulating drive motor, calendering steel belt, cooling box, Observation door, cooling water tank, ventilation circulation system, transfer roller, print collection table.
