Hom thiab cov yam ntxwv ntawm cov ntsia hlau chim rau extruders

Cov ntsia hlau thiab lub thoob ntawm lub extruder yog cov khoom tseem ceeb ntawm cov yas extruder, thiab lawv cov qauv tsim thiab cov ntaub ntawv muaj feem cuam tshuam rau qhov zoo thiab cov khoom ntawm cov khoom extruded. Hauv qab no yog ob peb hom thiab cov yam ntxwv ntawm extruder ntsia hlau chim.

1. Gradient ntsia hlau chim
Lub gradient ntsia hlau chim pib los ntawm qhov chaw pub mis, thiab qhov tob ntawm cov ntsia hlau groove maj mam txo kom txog thaum nws ncav cuag lub taub hau ntawm cov ntsia hlau. Hom ntsia hlau no tsuas yog siv rau cov mos thiab tawv polyvinyl chloride, polyolefin, thiab lwm yam.

2. Kev ntsuas hom ntsia hlau chim
Lub metering ntsia hlau thoob muaj qhov ntsuas ntawm 4-60 sib npaug sib npaug thiab sib sib zog nqus, thiab lub siab thiab cov khoom ntws ntawm tus ntsia hlau taub hau yog qhov ruaj khov. Yog li ntawd, cov khoom extruded muaj cov khoom zoo thiab tau siv dav hauv polyvinyl chloride, polyolefin, thiab engineering plastics. Qhov kev pub mis ntawm hom ntsia hlau no yog qhov sib npaug thiab sib npaug ntawm qhov sib npaug, thaum qhov tob ntawm cov ntsia hlau zawj hauv ntu compression maj mam txo qis.

3. Mutant ntsia hlau chim
Cov kev sib hloov compression ntu luv heev, tsuas yog 1-2D. Ntu kev pub mis thiab ntsuas yog ob qho tib si sib npaug thiab sib npaug qhov tob, thiab qhov ntsuas qhov ntev yog qhov ntev. Cov ntsia hlau no yog tsim los rau cov yas crystalline xws li polyphenylamine thiab polypropylene. Ua kom loj qhov kev hloov pauv mus rau ib puag ncig 5D, uas yog tsim rau kev ua cov yas nrog ntau qhov kub ntawm melting kub.

4. Torpedo taub hau ntsia hlau chim
Lub torpedo taub hau ntsia hlau chim yog nruab nrog lub taub hau torpedo nyob rau pem hauv ntej kawg ntawm qhov ntsuas. Hom ntsia hlau no muaj lub zog shear siab thiab zoo plasticizing nyhuv, haum rau granulation thiab molding ntawm polystyrene, polyethylene, phthalamide, methyl methacrylate, thiab polyvinylidene diazoxide. Vim muaj kev sib txhuam kub hauv lub taub hau torpedo, lub tshuab cua txias yuav tsum tau nruab.

5. Multi ntsia hlau extruder
Ib tug multi-ntsia hlau extruder feem ntau yog hais txog ib tug extruder nrog peb los yog ntau tshaj screws nyob rau hauv lub chim. Cov ntsia hlau tuaj yeem teeb tsa hauv qhov ncaj lossis V-puab. Kuj tseem muaj lub ntiaj teb ntau cov ntsia hlau extruder nrog cov ntsia hlau nquag thiab cov ntsia hlau tsav.

6. Twin ntsia hlau extruder
Twin ntsia hlau extruders yog tib yam li cov ntsia hlau extruders, yog li muab piv rau ib qho ntsia hlau extruders, ntxaib ntsia hlau extruders qee zaum hu ua multi ntsia hlau extruders. Twin ntsia hlau extruders tso cai rau qee qhov kev txheeb ze ntawm cov ntsia hlau hauv lawv cov qauv, tso cai rau kev sib xyaw zoo dua thiab cov khoom siv plasticization thaum lub sij hawm extrusion txheej txheem. Tsis tas li ntawd, ntxaib-ntsia hlau extruders kuj tseem siv tau los ua cov ntaub ntawv siab viscosity thiab kub rhiab heev, nrog rau qhov tshwj xeeb zoo.
