Three layers of cleaning and maintenance of the film blower

1. When cleaning the three -layer co -squeezing film, you can use a copper knife, copper stick or compressed air for cleaning, but do not damage the smooth surface of the screw and screw.
2. Before the three -layer co -squeezing film, the deceleration device and the lubrication device should be checked to avoid damage and noise caused by dry operation.
3. Within the range of the film formation, improve the molding temperature, cooling wind temperature, and foaming rate; the turbidity of the paint film increases, and the gloss is decreased; vice versa.
4. After the mold is uniform, put on the gloves to slowly pull up the pipe blank. At the same time, turn off the end of the tube blanks, slightly open the air intake regulating valve, and inject a small amount of compressed air into the mold. The core stick is in the center of the mold, and then carefully guides. Through the stable foam framework and human shape, the traction roller and the guide roller are used until the winding (if there is a pressure flower, the flower roller is pressed).
The import temperature of the inlet section of the three -layer co -squeezing film should be lower to prevent resin adhesion from blocking the inlet mouth. In addition, the resin is constantly compressed in the feed section, and the air should be discharged from the feed inlet to the back. According to the structure of the equipment, although the feed inlet of the three-layer co-squeezing film machine is not heated, the heat is transmitted through the machine, and the temperature of the feed inlet is about 50-90 degrees. This determines the temperature of the feeding part. The entrance is 50-90 degrees, and the ending point is equal to the melting point or sticky temperature. The temperature of this part can be set to linear heating.
