Based on the company's continuous efforts and accumulation of practical experience, the quality of our products has been continuously improved. We warmly welcome experts and scholars from all walks of life to visit our company. 1) Screw thread sleeve: The pitch of the standard screw thread sleeve is approximately between Pitch components (i.e., large-lead threaded components) are generally used in the feeding section and exhaust section of extruders. Narrow-pitch components (i.e., small-lead threaded components) are mainly used upstream of parts where the material needs to be compressed or filled with a large amount of filler, such as The thread pitch of the threaded sleeve upstream of the meshing block or sealing ring or between the operating sections (such as between feeding and vacuum) can be increased. As the pitch increases, the residence time and filling degree will be reduced, the residence time will be narrowed, and the drag will be reduced. The drag flow increases and is more sensitive to the increase in pressure (the increase in pressure leads to an increase in the possibility of leakage or reverse flow). However, under normal pressure conditions (or in the case of balance between the upstream delivery pressure and the downstream obstruction pressure), the wide The conveying capacity of a thread with a pitch is still greater than that of a thread with a narrow pitch.

In addition to the screw thread sleeves used for conveying, several conveying elements are also designed for special situations. For example, to cope with feeding difficulties and convey low-density materials, threaded sleeves are used to prevent leakage components.
2) Screw meshing block: The thread sleeves on the screw are composed of continuous threads, while the meshing block is made up of components with side disks that are stacked one by one. Its geometric shape is a discontinuous kneading. The characteristic parameters of the block include the total length, the number of meshing discs and the stagger angle of the meshing discs. We usually use B to represent the meshing disk, and add a specific value after B to indicate the actual shape of the meshing disk. For example: B means that the staggered angle of the meshing disks is degrees, there are a total of meshing disks, and the length of the meshing blocks is. The main task of the meshing block is to disperse and distribute mixing.

3) Dispersion mixing: Dispersion mixing is to reduce the particle size of components, break solid blocks or aggregates into particles, or reduce the phase size of mutually incompatible polymers. as small as required. This process is usually achieved by relying on a kneading disc with a large meshing length and a medium lead.

4) Distribution mixing: Distribution mixing is to achieve uniform spatial distribution of components, that is, to ensure uniform distribution of components in the melt passing through the distribution element in the mixing equipment. This is usually achieved by kneading the disc with a narrow blade and a small angle. In extreme cases, special distribution components are first used.
