"Environmentally friendly coating" vacuum spray operation strategy!

Vacuum spraying is mainly used for breathable windows, photo frames, kick wire and door cover and other flat or special-shaped lines of the coating, its equipment is simple, primer paint can be wire production, installation combination convenient, suitable for UV paint construction.

Common Misunderstandings

Ignore Workware Sizes
Mechanized coating equipment has requirements for work parts dimensions, vacuum sprayers are no exception, but the specific requirements of different manufacturers of equipment there are differences. Generally speaking, when vacuum spraying, the minimum work piece can not be less than 600 mm, the maximum width is not more than 300 mm, the maximum is not more than 100 mm, before production to confirm, otherwise can not complete the coating

Neglect Paint Box Cleaning
Since vacuum-sprayed coatings are 100% recycled, impurities and particles from work will be brought into the paint box, and poor surroundings of the machine can also cause contamination of the coating, so it is important to ensure that the machine is clean, especially the reservoir is clean.

coating amount setting is not allowed
coating volume size directly affects the coating effect, coating volume is too large is not easy to dry, coating volume is too small is difficult to level, paint film surface effect is poor. When vacuum spraying is constructed, the intake valve at the top of the machine box should be adjusted or the fan speed should be adjusted to set the amount of spray. In addition, the delivery speed will also affect the amount of coating, the faster the coating thicker, the thinner. In general, the coating volume control in 15-25g/m2 is more suitable, the actual coating should take into account the depth of the material catheter and coating effect needs.the viscosity ofcoatings
vacuum spray UV coatings are solvent-free coatings, need to be heated, if the heating temperature is too low or the heating time is too short, viscosity has not yet reached the construction requirements on the construction, will affect the entire coating effect. In general, it is appropriate to heat the coating to 75-80 degrees C.

note
to
check debugging before use
to do a comprehensive inspection and debugging of the equipment before powering on. First, to ensure that the coating is not less than 20 kg, second, to ensure that the air pressure is not less than 6 bar, third, to check the filter, filter core, to ensure smooth and effective filtration, if there is a blockage, should be cleaned up in time, fourth, to check the curing machine lamp, according to the size and shape of the work parts to adjust the treatment distance and angle To ensure that the lamp does not touch the work parts, five to check the box door and conveyor belt, to ensure that the box door closed, conveyor belt no foreign objects, six to ensure that the shape of the mold in and out of the warehouse and the work parts to maintain a high degree of matching, work parts outer diameter and mold import and export around the gap as far as possible to control in 2 to 3mm is appropriate.
in addition,
pay attention to the amount of coating, regularly check the paint capacity, filtration system and injection mold when
you encounter the card material immediately stop the discharge and timely processing, at the same time to check whether the conveyor belt is running bias phenomenon;after the use of

after cleaning and maintenance
equipment, should be regularly released in the reservoir residual paint, add the appropriate amount of thinner, start automatic cycle cleaning 5 to 10 minutes, to ensure that the pipeline is clear and the box clean, and then shut down the discharge of residual material, with a cloth to take the appropriate amount of thinner to wipe residual oil stains, stains. Clean lamps, conveyor belts and inspect electrical wiring, pipes and bearing components, filling regularly with oil or butter. It is important to note that do not turn on the fan when cleaning.
