First, the type of melt filter

According to the structure and replacement method of the filter element, the melt filter is mainly divided into the following types:

Plate filter: The filter element is a flat-plate filter screen, simple structure, easy to replace, but the filter area is limited, suitable for small flow, low pressure occasions.

Bag filter: The filter element is a bag-like filter screen, the filter area is large, suitable for large flow and high pressure occasions, but the replacement of the filter bag is more troublesome.

Candle filter: The filter element is cylindrical filter element, the filter area is large, easy to replace, suitable for high-precision filtration occasions.

Self-cleaning filter: equipped with automatic cleaning device, can realize online cleaning filter components, without stopping to replace, suitable for continuous production occasions.

Second, the selection of melt filter

Choosing the right melt filter requires consideration of the following factors:

Filtration accuracy: Select the aperture of the filter element according to the size of the impurities required to remove.

Processing capacity: Select the flow and processing capacity of the filter according to the production needs.

Working pressure: Select the pressure level of the filter according to the melt pressure.

Operating temperature: Select the temperature level of the filter according to the melt temperature.

Material: Select the material of the filter element and housing according to the nature of the melt and the type of impurities.

Cost: Consider the purchase cost, operation cost and maintenance cost of the filter.

Third, the application of melt filter

Melt filters are widely used in a variety of polymer processing industries, such as:

Plastic processing: Used to filter polyethylene, polypropylene, polyvinyl chloride and other plastic melt, improve the transparency of plastic products and mechanical properties.

Chemical fiber production: used to filter polyester, nylon and other chemical fiber melt, improve the strength and uniformity of the fiber.

Rubber processing: used to filter rubber compound, improve the quality and performance of rubber products.
