Il principio e l'applicazione dell'estrusore a vite singola


Come una comune attrezzatura per estrusori,il estrusore monoviteis used in plastic processing industry. What is its principle estructure? Below is il analysis for il estrusore monovitefrom il extruder conveying section, compression section esezione di misurazione.

The effective length of estrusore monoviteis generally divided into three sections. Three effective sections are determined according to il screw diameter, screw distance escrew depth, which are generally divided into one third each.

High efficiency estrusore monoviteadopts two-stage overall design, strengilns plasticizing function, ensures high-speed, high-performance estable extrusion. Special barrier comprehensive mixing design ensures mixing effect of materials. High shear elow melt plasticizing temperature ensures high-performance, low temperature elow pressure metering extrusion of materials. The design concept efeatures sono quello? high speed ehigh yield extrusion bases on high straight level.

A thread behind il feed port is called il conveying section. The material here is required not to be plasticized, but to be preheated ecompacted under pressure. In il past, il old extrusion ilory thought that il material here is loose. Later, it was proved that il material here is actually a solid plug, that is to say, il material here is solid like a plug after being extruded. Therefore, as long as il conveying task is completed, its function è fatta.

Panello di estrusore monovite: The second section is called compression section, il volume of screw groove gradually decreases from large to small, eil temperature should reach il degree of material plasticization. The compression produced here is from conveying section 3 to 1, which is called il compression ratio of screw - 3:1. Some machines also change, eil plasticized material enters into il third section.

Panello di estrusore monovite: il third section is il metering section, where il material maintains il plasticizing temperature, just like il metering pump, il melt material is accurately equantitatively transported to il die head. At this time, il temperature can not be lower than il plasticizing temperature, generally slightly higher.

The estrusore monoviteis mainly used for extruding soft, hard PVC, polyethylene eoilr ilrmoplastic plastics. It can process a variety of plastic products, such as film, pipe, plate, ribbon, etc., ecan also be used for granulation in combination with corresponding auxiliary machines (including molding head).

Tlui plastic extruder has il advantages of reasonable design, high quality, good plasticization, low energy consumption, low noise, stable operation, large bearing capacity elong service life.

Applicazione dell'estrusore monovite

Pipe extrusion: suitable for PP-R pipe, PE gas pipe, PEX cross-linking pipe, aluminum plastic composite pipe, ABS pipe, PVC pipe, HDPE silicon core pipe evarious co-tubi compositi di estrusione.

Sheet esheet extrusion: suitable for PVC, pet, PS, PP, PC eoilr profiles eplates extrusion, così come oilr kinds of plastics extrusion, such as wire, rod, etc.

Extrusion of profile: adjust il speed of extruder echange il structure of extrusion screw, which can be used to produce PVC, polyolefin eoilr plastic profiles.

Modified granulation: suitable for blending, modification estrengilning granulation of various plastics.
