How to Jinan Jinan Xu Hui Xu Hui electrophoresis equipment electrophoresis equipment electrophoresis equipment manufacturers Co. electrophoresis foam to reduce the generation after electrophoresis on how to reduce the cleaning foam fresh ultrafiltration electrophoresis after the cleaning process (UF) UF circulating liquid and organic liquid inclusive fresh UF solution containing low molecular weight resin (content of about 0.3% or less), the bath containing the discharge cycle UF (solid content from about 0.5% to 1%). Foam when air enters the cleaning fluid, foam can paint in general by the film material portion and the solvent portion of the composition of the volatile situation in spray serious?. Film material part title solids or volatile. Powder coatings and solvent-free coatings for solvent evaporation; a solid score of 100% was volatile thermoplastic coating (such as nitro paint) film formation process is only solvent evaporation, not accompanied by a chemical reaction. Thus solids equivalent to not volatile. Forming thermosetting coating process not only the solvent to evaporate, accompanied by the curing of a chemical reaction (oxidation, decomposition, polymerization, condensation reaction), resulting in generation increase or decrease the weight of the film phenomenon during film formation, thereby resulting in the coating The solid component (or volatile) part of the film-forming material weight is not necessarily the same. Electrophoretic paint belongs to thermosetting coating. And generally dried at 150-180 ℃ high temperature to cure, cathodic electrodeposition coating below 110 ℃ only out of water and volatile organic solvents, not curing, wiping still dissolved with the appropriate organic solvent, at a predetermined temperature to cure during the decomposition temperature of low molecular weight substances, and at a predetermined curing temperature for a certain time to cure (ie no longer solvent wipe off), heating loss occurs. Electrophoresis paint and bath below 110 ℃ drying the left part of the non-volatile solids electrophoretic paint. Electrodeposition bath of solids is one of the main process parameters electrophoretic coating directly affects the quality of the coating. Usually in the case of the anode electrophoretic coating bath solids control in 10% to 15% range. Into the plant electrophoretic paint solids with the product type and there are different, there are up to 60% -70%, with about 50 percent and a low of about 40 percent solids, is generally agreed upon by both parties supply standards. Determination of electrophoretic paint solids: the law applies to paint and semi-finished products, bath, measured liquid UF resin solids electrophoresis. Specific measuring points: ① Weigh specified weight of sample, stored in small aluminum pan or evaporating dish, dried at 105 soil 2 ℃ temperature for 3 hours, weigh; ⑨ sample weight provides as follows; Sample Type Sample said the average 2.0-2.5 UF was 10-15 ① Test results take two parallel trials for quantity (g) resin, semi-finished products 1.0'-1.5 1.5-2.0 electrophoretic coating bath The relative error of two parallel test is not more than 3%?
