1. The working room should be cleaned every time the vacuum coating equipment completes more than 200 coating procedures. The method is: repeatedly scrub the inner wall of the vacuum chamber with a saturated solution of caustic soda (NaOH), (note that the human skin can not directly contact the caustic soda solution to avoid burns) The purpose is to make the coated film material aluminum (AL) react with NaOH. After the reaction, the film The layer falls off and releases hydrogen. Then clean the vacuum chamber with clean water and clean the dirt in the fine suction valve with a cloth dipped in gasoline.

2. When the rough pump (slide valve pump, rotary vane pump) works continuously for one month (half in the rainy season), new oil needs to be replaced. The method is: unscrew the oil bolt, drain the old oil, and then start the pump for a few seconds to completely drain the old oil in the pump. Tighten the oil plug and add new oil to the rated amount (observed by oil sight glass). After using for more than half a year, the oil cap should be opened when changing the oil, and the dirt in the tank should be wiped with a cloth.

3. The diffusion pump has been used continuously for more than 6 months, the pumping speed is obviously slow, or the operation is improper, fill into the atmosphere, remove the connecting water pipe, remove the electric stove plate, unscrew the first-stage nozzle, first use gasoline to connect the pump cavity and pump Clean the tank again, then wash it with washing powder and water, and then rinse thoroughly with water. After the water evaporates, install the pump tank, add new diffusion pump oil, and install it back to the body, connect the water pipe, and install the electric stove Disk, you can reboot. Before restarting, pay attention to leak detection. The method is: start the maintenance pump and close the door. After a few minutes, observe whether the vacuum degree of the diffusion pump reaches 6X10 Pa. Otherwise, leak detection is required. Check whether the joint is equipped with a sealing rubber ring, or the sealing ring is crushed. Heat up after eliminating the hidden danger of air leakage, otherwise the diffusion pump oil will burn the ring and cannot enter the working state.
