    Core tip: the thickness of paint film mainly depends on the rate of object lifting and the viscosity of paint liquid After controlling the viscosity of paint liquid according to the above requirements, According to the maximum degree of 30 um film, according to different equipment, experiment to determine the appropriate lifting rate Lift the coated object evenly at this rate The lifting speed is fast and the film is thin; the lifting speed is slow and the film is thick and uneven Dip coating sometimes results in thickness difference between the upper and lower part of the coating film, especially in the lower edge of the coating To improve the coating Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Paint Home News: the thickness of paint film mainly depends on the speed of object lifting and the viscosity of paint liquid After controlling the viscosity of paint liquid according to the above requirements, according to the maximum degree of paint film about 30um, according to different equipment, experiment to determine the appropriate lifting rate Lift the coated object evenly at this rate The lifting speed is fast and the film is thin; the lifting speed is slow and the film is thick and uneven Dip coating sometimes results in thickness difference between the upper and lower part of the coating film, especially in the lower edge of the coating In order to improve the decorative property of the coating, the excess paint drops can be removed by hand with a brush when the coating is dipped in a small batch, and these paint drops can also be removed by centrifugal force or electrostatic force equipment The soaking time of wooden parts shall not be too long, so as to avoid excessive paint inhalation of wood, resulting in slow drying and waste After large objects are dipped and coated, they shall be sent to the drying room after the solvent is basically volatilized During the inspection, the paint on the thicker coating part shall not stick to hands or have finger marks Continuously pay attention to the viscosity measurement of the paint Each shift shall measure the viscosity 1-2 times If the viscosity increases by more than 10% of the original viscosity, the solvent shall be added in time When adding solvent, the dip coating shall be stopped After mixing, determine the viscosity, and then continue the operation Attention shall be paid to the mounting and hanging of coated objects In order to ensure that the workpiece is in the best position during dip coating, the hanging device and mounting method are designed by trial dip in advance The maximum plane of the coated object shall be close to the vertical, and other planes shall be 10 ° - 40 ° to the horizontal, so that the coating surface of the residual paint can flow out more smoothly, and the phenomenon of "paint pocket" or "air bag" shall not occur as far as possible In order to prevent the diffusion of solvent in the workshop and dust falling into the paint bath, the paint bath shall be protected Outside the operation time, the small dip tank shall be covered, and the large dip tank shall be cleaned with solvent Strengthen the ventilation equipment to prevent the harm of solvent vapor; pay attention to the arrangement of fire prevention and regular inspection 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,
