Although the quality of enameled wire depends to a large extent on the quality of raw materials such as paint and wires and the objective condition of machinery and equipment, if you do not pay attention to a series of problems such as baking, annealing, and vehicle speed during operation, and understand their interrelationships, Without mastering the operating technique,
If you do not do a good job in inspection and parking, and do not do a good job in process hygiene, even if the objective conditions are good, you cannot produce high-quality enameled wire. Therefore, the decisive factor for making enameled wire is people, and it is people's sense of responsibility.
1. Before starting the catalytic combustion hot air circulation enameling machine, the fan should be turned on to make the air in the furnace circulate slowly. The furnace and catalytic zone are preheated by electric heat, so that the temperature of the catalytic zone reaches the light-off temperature of the specified catalyst.
2. Three diligence and three inspections in production operations.
The work scale paint film is measured once an hour, and the zero position is corrected by the microcard before the measurement. When measuring, use the microcard and the line to maintain the same speed, and the large line should be measured in two vertical directions.
The alignment and tension relaxation of the front and rear are often observed and corrected in time. Check for proper lubrication.
Common enameled wires are often observed for unfavorable phenomena such as paint surface and peeling during the coating process, find out the reasons, and correct them immediately. For inferior products in the car, remove the axle in time.
Check whether each running part is normal during operation, and pay attention to the tightness of the pay-off shaft to prevent coiling, wire breakage and wire diameter thinning.
Check the third degree According to the process requirements, check the temperature, speed and viscosity.
Check whether the raw material production process continues to pay attention to whether the raw material meets the technical requirements.
3. In the production of enameled wire, attention should also be paid to the problem of deflagration. The fire burns as follows:
One is that the whole furnace is completely on fire, which is often caused by the high density of steam on the cross-section of the entire furnace or the high temperature of the furnace; the other is that when threading, the amount of paint on several lines is too much, causing several lines to catch fire. Strictly control the temperature of the process furnace to prevent the occurrence of burning, and secondly, to ensure smooth ventilation of the furnace.
4. Tidy up after parking.
The finishing work after the stop is mainly to clean the old glue on the furnace mouth, clean the paint tank and guide wheel, and do a good job of sanitation of the paint charter and the surrounding environment. To keep the paint tank clean, if you do not drive immediately, cover the paint tank with paper to prevent dirt from entering.
