1. Detailed rules for lamination operation
⑴ Environmental requirements for the lamination room
① The sealing of the lamination room must be ensured, and the doors between the lamination room and the powder cleaning room, as well as the doors leading to the outside of the lamination room, must all be closed.
② The temperature of the lamination room should be controlled between 18 and 25 degrees, and the relative humidity should be controlled within the range of 20% -30%.
③ The air in the lamination room should be kept clean and dust-free, and the ground and equipment surfaces should be wiped free of dust by hand.
④ Before entering the lamination room, workers should wear white work clothes and hats neatly, and only after dust removal can they enter.
⑤ During normal production, there should be no more than 6 workers in the lamination room. When additional workers are needed to make large glass, the temperature and relative temperature should be closely monitored to ensure that they do not exceed the standard. Unauthorized personnel are strictly prohibited from entering the lamination room.
Preparation before powder cleaning
Before entering the powder cleaning room, semi-finished products must be inspected piece by piece, and only qualified glass can enter the powder cleaning room for powder cleaning.
⑶ Clear powder
After the semi-finished product enters the powder cleaning position, use a suction cup to suck up the upper piece and manually clean the powder.
① Vacuum the silicon powder between two pieces of glass using a vacuum cleaner.
② Wipe the surfaces of two pieces of glass with a coarse cloth to remove dust.
③ Fine wipe with a clean and dust-free polyester cloth dipped in alcohol to make the glass surface completely dust-free, bright and clean.
After the semi-finished glass enters the lamination position, it is manually laminated.
① Firstly, check the appearance quality of the glass, and after passing the inspection, lay the film. The film must be naturally laid flat and cannot be stretched.
② Place another piece of glass, paying attention to aligning the two pieces of glass up and down, and ensuring that the overlap does not exceed the standard requirements.
