Ultrafiltration system maintenance ultrafiltration system has two main functions: to effectively closed flushing system adequate supply of ultra-filtrate and purified water-soluble paint impurities, improve the utilization of electrophoretic paint. Important ultrafiltration system management is the amount of ultrafiltrate through daily flow ultrafiltration system needs to be checked and recorded, abnormal immediately take appropriate measures to deal with, when decreased by 30%, we must organize cleaning. The reason caused by low levels of roughly divided into the following areas: 1) the bath flow ultrafiltration device low, change the pressure setting, there is a lack of coarse filter, devices are often stalled (the device to stop running more than one hour) will be reduced by the amount, and may even cause the diaphragm (UF) is damaged; 2) bath temperature is too high; 3) failure of the active layer ultrafiltration membrane: active layer polarity switching charged material to the same polarity and bath itself, its role by time limit, its durability can be achieved under optimum conditions for several months. After the failure of the active layer is necessary to use the cleaning to restore its function, cleaning, should be strictly in accordance with the formula and the proportion of cleaning solution configured and carefully wash procedure according to painting equipment drying equipment, which will cause failure or ultrafiltration scrapped. EDRO system maintenance water equipment: The main two, ion exchange and reverse osmosis water. Electrophoretic coating of pure water are higher, while the water is only one of the test items: Conductivity (μm / cm). With paint cast groove need water conductivity to reach 10μm / cm or less, the water used for washing water required to achieve 50μm / cm or less painting equipment electrostatic spray equipment, water is the need for more indicators of water through the device to complete , it is also made into the raw water required for water equipment. For small production, small-scale electrophoretic coating industrial water users choose to buy more economical way. Ion exchange applicable to raw water conductivity of not more than 200μm / cm, more than 200μm / cm of raw water should be chosen manufacture reverse osmosis water pure, raw water conductivity greater than 1000μm / cm should be selected reverse osmosis water pretreatment Water softening to + pure water production process is completed. Urban water conductivity can call the local water company; groundwater, water, landscape, water conductivity of high painting equipment, basic need reverse osmosis water machine to complete the process water system. Ion exchange: ion exchange technology is widely used in the field of water treatment. Such as water softening, water desalination, high water preparation coating equipment gun, but also for the Food and Drug decolorization purification, heavy metals, chemical raw materials recovered. Ion exchange equipment yin and yang bed, mixed bed regeneration bed three varieties, sun bed, anion bed countercurrent regeneration using advanced technology, with a mixed bed column and cation resin regeneration within the relocation regeneration process, the regeneration bed is designed for female mixed bed resin shift operations outside regeneration process configuration, I Division also designed other types of ion exchange equipment. Coating equipment gun, Anqiu painting equipment, painting equipment provided by Sino Sino Painting Equipment Co. Qu. Linqu Sino Painting Equipment Co. (www.wfjn.com) (www.wfjn.com) (www.wftcsw.com) strong, credible, Shandong Weifang industrial automation control systems and equipment industry has accumulated a large number of loyal customers.
