Melt spray cloth is the core material of the mask. Melt spray cloth is mainly made of polypropylene, and the fiber diameter can be up to 1 ~ 5 microns.

Melting spray cloth is mainly used for:
1. Filtering materials
2. Medical and sanitary materials
3. Environmental protection materials
4. Clothing materials
5. Battery diaphragm material
6. Wipe the material

The extruder originated in England in the 18th century and was mainly used in the lead pipe, macaroni, brick and ceramic industries during the first half of the 19th century. In 1935, Germany produced extruders for thermoplastic plastics. In 1939, they developed plastic extruders into modern single-screw extruders

The screw extruder produced by Huatian Chemical Equipment Co., Ltd. relies on the pressure and shear force generated by the screw rotation, so that the material can be fully plasticized and evenly mixed through the mold forming. And achieve energy conservation and environmental protection.

The power part saves energy: the way to save energy is to save the residual energy of the motor by adopting a frequency converter. For example, the actual power of the motor is 50Hz, but you only need 30Hz for production in fact. Those extra energy consumption will be wasted.

The heating part saves energy: the heating part USES ceramic heater to save energy, the energy saving rate is about 30%~70% of the old resistance ring.

Melting spray production equipment manufacture is not complicated, mainly is the process debugging problem. Copy because involve in the temperature, pressure, mold, speed and other aspects of the parameter ratio, so need to keep running in and debugging, in order to make the product to achieve the best results. The main equipment of the production line includes feeding machine, screw extruder, filter device, metering pump, injection mold head assembly, Roots blower, air heater, receiving device and winding device.
