Advantages of using screen changer in extrusion plastic production line

The mesh screen changer is mainly used in the field of plasticizing materials. When the plasticizing materials flow through the filter, the foreign particles and impurities are filtered out to improve the quality of the products. Zhengzhou Haike mesh changer manufacturer provides mesh changer equipment including: automatic mesh changer, degradable materials mesh changer, cross-linked pipeline mesh changer, foam products mesh changer and other special mesh changer.

The application of mesh screen changer (also called mesh changer filter) in extrusion plastic production line mainly embodies four advantages, and is also the value of mesh screen changer.

1, filter out impurities in raw materials and improve the quality of products.

2. The plasticizing and homogenizing effect of raw materials is greatly improved by adding a mesh changer to increase the back pressure of the head. The product has more uniform texture and better smoothness, and the pressure resistance value of the product will be increased. This is also the reason why new materials are not replaced by impurities.

3. The rheological behavior of the material is changed from rotating flow to linear flow after the mesh changer is installed to avoid the appearance of "winding pattern" of the product. The porous plate and filter screen have the function of "damping" at the same time, so that the cross-section velocity of the whole melt can be as consistent as possible, avoiding the phenomenon of "polymer orientation" and laminar flow, so that the longitudinal strength of the product increases and the transverse strength decreases, thus affecting the quality of the product, because the flow velocity of the melt ring wall is very different from the flow velocity in the middle.

4. Installing a net changer to increase the back pressure of the head will help to remove the water vapor and volatile matter in the raw material, and improve the qualified rate of the product.

Selecting special mesh screen changer equipment according to different materials is beneficial to increase filtration efficiency and production capacity; Zhengzhou batte mesh changer manufacturer is a well-known mesh changer manufacturer with professional technical team and advanced processing equipment to meet the production needs of middle and high-end users.
