How to clean up after the spray gun is used

In our opinion, no matter what machine tools are used, they must be cleaned and maintained in time. This will not only prolong the service life of the machine, but also eliminate the manpower, material resources, financial resources, etc. in the next use. Wait. Let's share the following knowledge about how to effectively clean up the gun after it has been used.

Immediately after use of the spray gun, the spray gun and its accessories should be cleaned. The maintenance and cleaning of the medal is the main cause of the malfunction of the spray gun. When cleaning the suction feed gun, first remove the paint can and flow the suction tube into the cup. Then release the air cap 2-3 turns, block the air cap with a folded rag, and then pull the trigger. This allows the paint in the gun to flow back into the paint can.

It should be noted that the air pressure used should be low. When the paint can is still mounted on the gun, do not perform the above operation, otherwise the paint will splash out of the tank. Re-tighten the air cap and pour the paint from the paint canister back into the original large can. Clean the inside of the cup and the lid with a solvent and a thin brush. Wipe off the residue with a cloth dipped in solvent. Then pour a little clean detergent into the cup, pull the trigger, spray the cleaner, and clean the delivery tube. Then remove the air cap, soak in a thinner or solvent, and clean the clogged holes with a soft brush like a round-headed toothbrush or a straw broom. Remember, you should never clean these holes with something like iron wire or nails, because these holes are all precision drilled. Use a Shenzhen gun brush and solvent to clean the nozzle. Wipe the outside of the gun body with a rag that has been soaked in thinner, taking care to wipe off any traces of paint.

In the operation of cleaning the spray gun, etc., a large amount of solvent remains, and if it is directly dumped, it is wasteful and environmentally friendly. The solvent recovery machine uses high-temperature distillation to recover the dirty solvent, which can obtain a clean solvent, save a lot of solvent, and protect the environment.

Note: If the gun is not cleaned immediately after use, the nozzle will be partially or completely blocked, causing the spray from the spray gun to split (spray out dry paint fragments) or the spray shape is incorrect. This is especially true for enamels with additives. Because the enamel will harden inside the gun if it is not cleaned immediately after use.
