Embodiment Construction

[0008] Refer to the attached figure 1 A screw suitable for CPVC processing of the present invention will be described in detail below.

[0009] A screw suitable for CPVC processing according to the present invention has a structure comprising a screw body 1, on which a conveying section 2, a conveying heating section 3, a pre-plasticizing section 4, a plasticizing Section 5, exhaust section 6, extrusion section 7 and homogenization section 8, the thread pitch of the plasticizing section 5 is 60mm.

[0010] Driven by the rotation of the screw, the material continuously moves towards the tip of the screw, is conveyed rapidly through the conveying section 2, enters the pre-plasticizing section 4 through the conveying heating section 3 for pre-plasticization, and then enters the plasticizing section 5 for plasticization, undergoes shearing and gradually plasticize and melt, enter the exhaust section 6, depressurize to discharge the moisture and volatile matter in the material, an...

Abstract

The invention discloses a screw rod suitable for machining of chlorinated ploy vinyl chloride (CPVC), which belongs to the field of screw rods. The screw rod comprises a screw rod body, wherein a conveying section, a conveying heating section, a preplasticizing section, a plasticizing section, an air exhaust section, an extrusion section and a homogenization section are sequentially arranged on the screw rod body according to the movement direction of a material; and the thread pitch of the plasticizing section is 60mm. Compared with the prior art, the screw rod suitable for the machining of the CPVC has the characteristics of reduction in compression strength and shear strength, difficulty in material burning and the like, so that the screw rod has extremely high popularization and application value.

Description

technical field [0001] The invention relates to a screw, in particular to a screw suitable for processing CPVC. Background technique [0002] The screw of the extruder is an important part in the extruder, which is used to plasticize and extrude the plastic particles to form a plastic film. The screw is the heart of the extruder. The quality and productivity of the plastic products produced depend directly on the temperature uniformity, pressure, and stability of the extruded melt from the machine, and these parameters directly depend on the screw performance. structural performance. When the currently used extruder screw is processing CPVC, the screw pitch of the plasticizing section is too small, the compressive strength is increased, the shearing strength is increased, and it is easy to paste. Currently, there is no good solution. Contents of the invention [0003] The technical task of the present invention is to provide a kind of screw rod that is suitable for CPVC...
