Information
Melt-blown fabric processing technology is to use high-speed hot air to draw the fine flow of polymer melt extruded from the die orifice, so as to produce ultra-fine fibers which are suspected to be aggregated on the drum, and the die is formed by bonding itself. It is the most important part of the meltblown device. The symmetry of the product is closely related to the mold, so the processing accuracy is high.
1. In the process of designing the mold, the gate design is very important. Runner Tibetan glue is an important problem that causes Melt-blown fabric to turn yellow and become brittle. Whether the mold gate can be smooth or not is related to the smooth production of the mold. The hanger-type gate is the main flow channel of the melt blown cloth mold;
2. The uniformity of the wind knife is also related to the uniformity of the Melt-blown fabric;
3. The assembly form between the mold plates determines whether the mold will have leaking glue;
4. In the process of manufacturing and processing, precision machining must be performed. In particular, the smoothness and flatness of the nozzle should be manufactured and processed in place;
5. Melt-blown fabric polypropylene material is different from PET material, the size of the nozzle must be moderate, without excessive pursuit of small round holes. The hole diameter is too small, it is very easy to block the mold.
