PP Meltblown Non-woven Fabric Production Line
PP Meltblown Nonwoven Fabric Production Line includes raw material input, raw material dryer, extruder, screen changer, metering pump, die (single, composite), distribution plate, spinneret, netting device, winding device Wait.
The actual production process of melt-blown cloth is relatively complicated, involving many disciplines such as polymer science, fluid mechanics, airflow, spinning science, etc., and the requirements for equipment manufacturing are also high. The key is the complete set of production equipment for melt-blown cloth.
PP Meltblown Nonwoven Fabric Production Line Core Component
The die system of the melt-blown die assembly is composed of a bottom plate, a spinneret, an air plate, and a heating element. The uniformity of melt-blown products is closely related to the die head, but the processing accuracy of the melt-blown die head is very high, and the manufacturing cost of the die head is expensive.
The spinneret is the extrusion die for the production of melt-blown cloth.
The spinneret mold is a precision mold. The thickness of the melt-blown cloth depends on the spinneret. The precision of the mold cannot be reached, and the sprayed wire is too thick to achieve the barrier effect.
The production of spinneret nozzles is difficult. This kind of nozzle is small in size, and it is necessary to process a complex hole on the small nozzle, which is extremely difficult to process and takes a long time to process.
If the processing accuracy is not high, it is easy to cause blockage or affect the melt-blown flow rate and form crystallization, and the final melt-blown cloth produced will not meet the requirements.
Melt Blown Air Heater
The air heater is one of the main equipment in the melt-blown production process because a large amount of high temperature and clean air is required in the melt-blown process.
The air heater heats the air delivered by the Roots blower or air compressor to a specified temperature and then delivers it to the melt-blown die. It is not enough to rely on the small holes of the spinneret, and it needs to be stretched by the wind.
The air heater is a pressure vessel, and at the same time it must resist the oxidation of high-temperature air, so the material must be stainless steel.
When selecting a heater for PP Meltblown Nonwoven Fabric Production Line, you should pay attention to the following aspects:
- The air needs to be clean during the processing. First, the air source input to the air heater should be clean and dry, and the material of the part in contact with the air in the heater must be at least SUS304 grade;
- Because the air source in the normal process is provided by an air compressor or a Roots blower, the air heater should be a ducted heater with pressure bearing capacity;
- The heater selection should consider in detail factors such as air volume, temperature difference, and heat loss during pipeline transportation;
- The melt-blown process requires higher temperature control accuracy of the air heater. In terms of temperature control, a module with higher temperature control accuracy should be selected, and the specific surface temperature difference is large, which affects the stability of the air temperature.
Melt Metering Pump
The melt metering pump is a positive displacement conveying device, and the flow rate is strictly proportional to the speed of the pump.
The melt metering pump is used for precise metering, controlling the output and the fineness of the fiber, and continuously and uniformly transporting the melt to the spinneret. Melt blown cloth metering pump has the advantages of stable output pressure, improving product quality, increasing extrusion output, and reducing unit energy consumption.
The main function of the special screen changer for melt-blown cloth is to filter out the impurities in the melt, so as not to block the spinneret holes.
The special screen changer for melt-blown cloth is composed of the main body, a sealing component, a porous plate, a filter screen, and a switching device. The main body of the melt-blown cloth screen changer is made of special alloy materials through strict forging, surface heat treatment, and precise metal processing.
The machine requirement of melt-blown material is to change the screen continuously. Generally, a double-station screen changer is used, and different screws are matched with metering pumps of different specifications.
Electret equipment is to increases filtration efficiency and reduces filtration resistance. The equipment consists of three parts, the generator host, the step-up transformer, and the electret processing frame.
