- Dip-coating method of coating operation precautions and equipment maintenance
- 2016-03-11 15:00:24
According to the paint coating properties and paint film the degree requirements, pre-determined dip-coating groove in the suitable viscosity of coating, in the process of leaching paint tested periodically and timely adjust dip-coating slot coating viscosity, supplement the original paint viscosity is too low, too high viscosity can be thinner, appropriately.
Dip coating when appropriate mixing prevent dip-coating groove precipitation. After adding new paint mix, need to stand for a certain time, can be carried out after eliminating bubbles leaching paint job.
Temperature on the coating viscosity obstruction is very big, should according to the working environment temperature change, take the appropriate heating or cooling, dip coating of the tank inside coating for temperature control in the scope.
Avoid being coated content into the groove and the groove too fast, make the dip-coating slot coating have bubbles, strenuous exercise interfere with film quality. Not varnished, dip-coating slot should be sealed, in order to prevent dust or other dirt mixed with groove pollution coatings.
5 min before leaching paint job start drafty equipment, homework also should make its operation more minutes after stop.
Coating should level off is smooth, can not have flowed, super wrinkled, orange peel, bubbles and severe granule, otherwise should be polished, or to drop film painted again. To paint film is the best way to blow sand, also can use other methods.
Leaching paint coating equipment maintenance, check stirring, heating, cooling device, found in a timely manner to eliminate the fault, to ensure that the device is working properly.
To check more than paint with electrostatic generator, to ensure the voltage stability, to prevent spark discharge. Fire protection device when hou in office should be in good condition, in case of one thousand in a timely manner to eliminate accident. Don't let the noise of the coated material collision slot wall, and prevent the coated material drop dip-coating groove, so as not to damage the dip-coating slot and affiliated facilities thereof. By dip coating of paint fall slot should be remove in time.
