Meltblown nonwovens die series

Product Show:

Meltblown nonwovens process is the use of high-speed hot air on the die nozzle extruded polymer melt stream for stretching, thus forming ultra-fine fibers and cohesion in the condensation curtain or roller, and rely on their own adhesion and become. The die head is the key part of the meltblown equipment, and the uniformity of the product is closely related to the die head, so the processing detail is required to be high.

Technical characteristics:

According to the different characteristics of raw materials (viscosity, temperature, rate) designed hanger type flow to, melt distribution more uniform.
The polishing finish of the mold cavity is 0.01um-0.03um.
Adopting special hot air flow heating device, with good heating efficiency and heat exchange efficiency, low energy consumption.
Unique wind slot structure design, stable air pressure, symmetrical airflow on both sides, uniform airflow in the direction of width. The width of the air gap is adjustable in real time, and it is convenient to adjust.
According to different raw materials optimized by computer simulation, customized special streamlined flow path, can get continuous unobstructed flow surface;
- Spinneret replaceable structure, silk hole compression runner structure design, stable material flow, uniform silk; 
- The air outlet is equipped with adjustable air flow device to realize rapid adjustment of local air outlet flow; 
- The surface is hard chrome plated, the fasteners are 12.9 grade high strength bolts, and the heating is controlled by stainless steel heating rods or liquid temperature zones; 
- Customizable heat preservation device, effectively reduce heat loss, reduce production costs; 
- Combined mold body, simple structure, easy to disassemble and clean;
