There are a wide variety of paper chemicals, and the wetting composition of the paper machine is complicated. Therefore, when adding the wet chemical additives, Paper Making Chemical the basic theory of surface chemistry and colloidal chemistry is combined with the environment in which the chemicals are used according to the characteristics of the chemicals and the environment used in the chemicals. Out of the experience, Paper Making Chemical to gradually explore; in the wet Department of papermaking problems, but also according to these principles, and not blindly, free to add or remove chemicals.
The whole paper machine wet system is like a "black hole", it is complex, invisible and fragile, in the machine running for some time will reach a certain balance, Paper Making Chemical when the external conditions change, this balance will be broken, And cause a series of changes, Paper Making Chemical to the paper machine operation problems, so follow this idea, the paper machine wet operation and join the chemical given the following recommendations:
- to keep the paper machine system running smoothly, Paper Making Chemical to meet the quality and copy the premise of adding chemicals to reduce the type and quantity;
- in the need to replace the new chemicals, to take a gradual replacement method, Paper Making Chemical to consider the new chemicals and the original system compatibility, the operation of the follow-up process have no effect;
- to follow the basic principles of papermaking, Paper Making Chemical although the paper machine speed continues to improve, more advanced automation control, but some of the basic principles of papermaking operations has not changed, some copy of the parameters are basically unchanged, Paper Making Chemical need to keep in mind and resolutely implement strict process conditions, Such as the pH of the slurry, the pH of the system, the cationic demand and the zeta potential of the wet end (which reflects the change in the ratio of water, Paper Making Chemical slurry and different pulp used in the system) and the white water concentration Keep)
- to strengthen the wet end of the detection, data collection, collation and analysis, paper is a continuous process, from the long term there must be a rule to find. Paper Making Chemical Record the operation of the wet end of the paper machine at any time, for the follow-up problems to provide analysis and solve the problem of reference. Paper Making Chemical Which is currently a considerable number of domestic enterprises do less than the place;
Paper industry is a fiber-based chemical processing industry, in the pulp, bleaching, beating, paper making and paper processing after the process of the whole process of the various stages, are inseparable from the application of various chemicals, Giving the paper a variety of special superior performance, Paper Making Chemical can use poor fiber raw materials to produce thinner, more white, Paper Making Chemical more firmly paper; some can make the production process optimization, paper machine running speed, Paper Making Chemical and has a significant reduction in the environment The advantages of pollution, to the paper industry to bring good economic benefits.
Water treatment includes the water treatment of papermaking systems, cooling water treatment, water treatment, papermaking wastewater treatment, Paper Making Chemical the use of the varieties of chemicals is relatively simple.
Function: Water treatment chemicals in the entire papermaking process to ensure that the paper system water quality, reduce water consumption, Paper Making Chemical effective maintenance and extension of the use of the water plant cycle to ensure that the environment from pollution.
