Cause abnormal electrophoretic paint adhesion occurs reasons: (1) to be coated on behalf of the thermal no symmetry, so that the entire DC density is too great. * Phosphate coating purification (fingerprints, spots India, pickling scum). * To be coated on behalf of purification (yellow rust, cleaned agents, flux, etc.) * before solving process abnormalities: deoxy no good, washable not sufficient, deoxygenated liquid and liquid phosphate residues; phosphate coating has blue, yellow rust before, the same friction incurred called to solve a strange friction. (2) purification tank impurity ions, the conductivity is too large, high levels of inorganic solvent bath, low ash content. (3) Swimming Tu voltage is too high, the amount of high bath to form the film destroyed. 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 unusual take appropriate measures to deal with immediate coating equipment electrostatic powder machine, decreased by 30% when Tu installed equipment, it 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 of coating mounted equipment spray machine, and may even cause the diaphragm (UF) is damaged; 2) bath temperature is too high; 3) ultrafiltration membrane active layer failure: activation layer polarity switching charged material to the bath itself very Spray painting equipment of the same machine, and its role is time-limited, and its durability under the best conditions can reach 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 press the cleaning procedure, otherwise it will cause ultrafiltration failure or scrapped.
