Coating knowledge: dip coating process

Core tip: China new paint news: dip coating is to dip the coated object into the paint, so that the surface of the coated object adheres to the paint, and then drips off the redundant paint to form a film The dip coating equipment is simple, easy to realize mechanization, high production efficiency, and less paint loss, which is suitable for the coating with complex shape Dip coating equipment usually includes dip coating tank, mixing device, skimming device, coating heating and cooling device, conveying suspension device and necessary fire protection device The dip coating tank is divided into continuous operation ship shaped tank and intermittent operation rectangular tank The size of the tank body depends on the size of the coated object Under the condition that the coated object does not collide with the tank wall during the dip coating, the size of the tank body shall be minimized Paint agent, top 10 Chinese wall paint brands Recommended introduction: interior wall paint and exterior wall paint can achieve beautiful, clean and pleasant effects, but the effects in different environments are different, so the color of the paint will be different There are ten brands of Chinese paint, ten brands of global paint, ten brands of Chinese wall paint, and ten brands of Chinese paint, Famous trademark of Chinese paint and coating In private rooms, most of us choose according to our own personality, personal hobbies and living habits The younger generation will choose the interior wall paint with rich colors and bright colors, while the older ones will have some working experience Home of coatings news: China's new coatings news: dip coating is to dip the coating into the coating, so that the surface of the coating adheres to the coating, and then drips off the excess paint to form a coating The dip coating equipment is simple, easy to realize mechanization, high production efficiency, and less paint loss, which is suitable for the coating with complex shape Dip coating equipment usually includes dip coating tank, mixing device, skimming device, coating heating and cooling device, conveying suspension device and necessary fire protection device The dip coating tank is divided into continuous operation ship shaped tank and intermittent operation rectangular tank The size of the tank depends on the size of the coating Under the condition that the coating does not collide with the tank wall during the dip coating, the volume and opening area of the tank should be minimized to reduce the feeding amount of the coating and the solvent volatilization In order to prevent the deposition of pigments and fillers in the tank and ensure the coating uniformity, a mixing device must be equipped There are two kinds of mixing devices: pump circulation mixing device and mechanical mixing device Because of the large amount of coating put into the dip tank at one time, it needs to be used repeatedly for a long time, so the dip coating process requires high stability of the coating, slow settling speed and less solvent volatilization Generally baking coating and water-based coating are suitable for dip coating, such as asphalt baking, alkyd baking, water-based acrylic baking, etc., while quick drying coating, curing agent curing coating and coating with more fillers are not suitable for dip coating The craftiness of the coating has a great influence on the dip coating process, and the temperature of the coating must be strictly controlled because the viscosity is closely related to the temperature Natural dropping method and electrostatic method are mainly used to remove residual paint Electrostatic paint removal is fast, which can improve the defects of inconsistent thickness of upper and lower coating Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
