Embodiment 1
[0022] Put the positive grid to be coated at a temperature of 95°C for 5 hours, then cool it down to room temperature and start coating. The coating speed is 100 pieces / min, the surface drying kiln conveyor belt speed is 105 pieces / min, and the surface drying temperature is set at 150°C. , the outlet temperature of the low-temperature kiln is set at 1°C, and the wind speed of the cold air is controlled at 800m 3 / h, enter the surface drying kiln after coating, acid pouring, and overpressure rollers, and then enter the low-temperature kiln. After reaching 15°C, collect the film, put it on the shelf, and enter the curing room for curing and drying. The curing and drying control steps are as follows: the first step is at 65°C, the humidity is 99%, and the time is 20h; the second step is at 55°C and the humidity is 80%, the time is 10h, the temperature of the third step is 55°C, the humidity is 50%, the time is 8h, the temperature of the fourth step is 70°C, the humidity is 0%, th...
Embodiment 2
[0026] Place the negative grid to be coated at a temperature of 95°C for 5 hours, then cool to room temperature and start coating. The speed of coating is 100 pieces / min, the speed of the surface drying kiln conveyor belt is 105 pieces / min, and the surface drying temperature is set at 120°C. , the outlet temperature of the low-temperature kiln is set at 3°C, and the wind speed of the cold air is controlled at 800m 3 / h, after coating, acid spraying, and overpressure rollers, enter the surface drying kiln, and then enter the low-temperature kiln. After ℃, collect the film, put it on the shelf, and enter the curing room for curing and drying. The curing and drying control steps are as follows: the first step is at 50°C, the humidity is 99%, and the time is 24h; the second step is at 55°C, and the humidity is 80%. , the time is 6h, the temperature of the third step is 60°C, the humidity is 50%, the time is 6h, the temperature of the fourth step is 75°C, the humidity is 0%, and th...
