Three points to keep your vacuum coating machine "forever young"


Many people do not know how to maintain and maintain after having their own vacuum coating machine, so that the quality of vacuum coating machine is greatly reduced. Today IKS PVD to explain the three points of vacuum coating machine maintenance related knowledge.


1, clean

The vacuum coating equipment shall clean the studio once every 200 or more coating procedures are completed. The method is to repeatedly scrub the vacuum chamber wall with NaOH saturated solution, (pay attention to the human skin can not directly contact the caustic soda solution, so as not to burn) the purpose is to make the coated aluminum (AL) react with NaOH, after the reaction, the membrane layer falls off, and release hydrogen. Then clean the vacuum chamber with water and clean the dirt inside the fine suction valve with cloth dipped in gasoline.


2. Replace with new oil

When the rough pump (slide valve pump, rotary vane pump) continuous work for a month (the rainy season in half), need to replace the new oil. The method is: screw open oil bolts, put off the old oil, and then start the pump for a few seconds, so that the old oil in the pump completely discharged. Unscrew the playback oil bolt and add new oil to the amount (observed by oil mirror). Continuous use for more than half a year, oil should be changed when the oil cap open, with a cloth to wipe the dirt inside the box


3. Clean the inside

Diffusion pump use more than six months in a row, pumping speed significantly slower, or improper operation, filling the air and down link pipes, electric plate, will be squeezed out of the primary nozzle, use gasoline pump cavity and pump bravery to clean first, clean with detergent water again, and then clean with clear water thoroughly clean, moisture volatilizes dry after installed pump, add new oil diffusion pump, and put back into the body, connected pipes, installed electric stove disk, can restart.Pay attention to leak detection before restarting the machine.The method is: start the maintenance pump, close the door, a few minutes later, observe the diffusion pump part vacuum is up to 6X10 pa, or to carry out leak detection.Check whether the joint is fitted with sealing ring, or the sealing ring is crushed.Remove the potential gas leakage before heating, otherwise the diffusion pump oil will burn the ring, unable to enter the working state.
