1. The hanger-type runner is designed according to the characteristics of the raw materials (viscosity, temperature, rate); 2. Rib finish of mold cavity is 0.01um-0.06um; surface finish of melt flow is 0.03um-0.04um; 3. Using heating rod heating or heating plate heating outside, hot oil circulation temperature control;
Melt-blown nonwovens uses high-speed hot air flow to draw a thin stream of polymer melt extruded from the die orifice. Thus, ultra-fine fibers are formed and collected on a screen curtain or a roller, and at the same time, they are bonded to each other to form a melt-blown nonwoven fabric.
The production process of melt blown cloth is mainly:
1. Melt preparation
4. The melt is extruded from the spinneret
5. Melt flow drafting and cooling
