Tawm tsam keeb kwm yav dhau los ntawm txoj kev loj hlob sai ntawm polyethylene (PE) kev hloov kho kev lag luam, kev tsim qauv tsim, kev tsim khoom, thiab kev siv PE hloov peb -screw granulators, ua cov khoom siv tseem ceeb, cuam tshuam ncaj qha rau cov khoom zoo, kev nyab xeeb ntawm kev tsim khoom, thiab kev lag luam qib thev naus laus zis. Cov qauv siv los ua cov txheej txheem tseem ceeb thoob plaws hauv tag nrho cov txheej txheem ntawm kev tshawb fawb thiab kev tsim khoom, tsim khoom, tshuaj xyuas, thiab siv. Lawv muab cov chaw tsim khoom nrog kev sib koom ua ke kev taw qhia thiab muab cov neeg siv lub hom phiaj kev ntsuas rau kev ntsuam xyuas thiab kev xaiv, ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev noj qab haus huv thiab kev loj hlob ntawm kev lag luam.
Cov qauv tam sim no ncaj qha lossis ncaj qha ntsig txog PE hloov kho peb - cov ntsia hlau granulators feem ntau suav nrog kev nyab xeeb ntawm kev siv tshuab, kev ua haujlwm tsis zoo, kev ntsuas kev siv hluav taws xob, cov khoom siv thiab kev tsim khoom zoo, thiab kev tiv thaiv ib puag ncig. Nyob rau hauv thaj tsam ntawm kev nyab xeeb kev nyab xeeb, lub teb chaws lossis thoob ntiaj teb kev lees paub cov cuab yeej siv tshuab kev nyab xeeb yog feem ntau hais txog, qhia meej cov cai rau cov khoom siv thaum muaj xwm ceev nres, tiv thaiv npog, hluav taws xob hauv av, thiab siab - kub tiv thaiv kev ceeb toom tiv thaiv kev raug mob thiab hluav taws xob raug mob. Rau cov khoom siv uas muaj kev kub siab - kub melting thiab siab - qhov siab extrusion seem, cov qauv feem ntau hais txog qhov yuav tsum tau teeb tsa ntawm kev tiv thaiv overload, kub tshaj - txwv lub tswb, thiab lub siab muaj kev nyab xeeb li qub kom ntseeg tau tias lub hwj chim txiav raws sij hawm- tawm los yog siab nyem raws li kev ua haujlwm tsis zoo.
Hais txog kev ua haujlwm tsis zoo, cov qauv tsim nyog tau tsim cov qauv kev sim thiab cov kev xav tau rau cov ntsuas xws li lub taub hau taub hau, qhov ntev - mus rau - txoj kab uas hla, qhov siab tshaj plaws, qhov siab tshaj plaws torque, tus naj npawb ntawm cov cua sov zones, thiab kev tswj qhov kub thiab txias kom ntseeg tau tias qhov sib piv ntawm cov cuab yeej nyob rau hauv cov formulations sib txawv thiab yuav tsum muaj peev xwm ntau lawm. Piv txwv li, kev tswj qhov kub thiab txias yog feem ntau yuav tsum nyob rau hauv ± 2℃ntawm cov nqi teeb tsa kom ua tau raws li cov txheej txheem kev ruaj ntseg ntawm cov cua sov- cov khoom rhiab thiab muab tub lim thaum hloov PE. Rau qhov tshwj xeeb elastic lossis kho qhov sib txawv ntawm peb - ntsia hlau compressors, cov qauv kuj tseem qhia cov txheej txheem kev soj ntsuam rau kev hloov pauv ntau, kev hloov kho qhov tseeb, thiab lub neej qaug zog kom ntseeg tau tias kev hloov pauv tau zoo thiab ruaj khov.
Kev ntsuam xyuas kev siv hluav taws xob tau nce zuj zus los ua qhov tseem ceeb. Qee cov qauv kev lag luam tau qhia txog cov khoom siv hluav taws xob siv hluav taws xob lossis kev ntsuas kev siv hluav taws xob, ua rau cov tuam txhab ua kom zoo tshaj qhov kev sib txuas lus tsim, cua sov thiab cua txias schemes, thiab txheej txheem txheej txheem kom txo tau lub zog noj thaum lub sij hawm tsim khoom. Qhov no tsis yog tsuas yog ua raws li lub teb chaws kev txuag hluav taws xob thiab kev txo qis emissions tab sis kuj pab cov tuam txhab tau txais txiaj ntsig zoo hauv cov nqi khiav lag luam.
Cov ntaub ntawv thiab kev tsim cov qauv zoo qhia cov ntaub ntawv, cov txheej txheem kho cua sov, qhov nyuaj ntawm qhov chaw, thiab kev ua haujlwm raug ntawm cov khoom tseem ceeb xws li cov ntsia hlau, cov thoob, gearboxes, thiab cov bearings kom ntseeg tau tias lawv hnav tsis kam, corrosion resistance, thiab seem stability. Rau cov khoom uas tuaj rau hauv kev sib cuag nrog PE molten thiab hloov cov neeg ua hauj lwm, cov qauv feem ntau yuav tsum tau siv cov zaub mov -qib los yog corrosion tshwj xeeb- cov alloys resistant thiab txwv tsis pub tso tawm cov khoom tsis zoo kom ua tau raws li kev nyab xeeb hauv thaj chaw xws li ntim khoom noj thiab khoom siv kho mob.
Hais txog ib puag ncig cov kev cai, cov qauv tsim kev txwv tsis pub muaj suab nrov, tswj kev vibration, cua txias nruab nrab emissions, thiab pov tseg pov tseg kom txo tau qhov cuam tshuam ntawm kev ua haujlwm ntawm cov khoom siv. Qee cov qauv hauv cheeb tsam kuj txhawb kom siv cov tshuab ua kom txias dua thiab qis - suab nrov tsim, uas cuam tshuam txog lub tswv yim ntawm kev tsim ntsuab.
Kev ua raws li cov qauv no tsis yog tsuas yog txhim kho tag nrho cov khoom zoo thiab kev nyab xeeb ntawm PE hloov peb -screw granulators tab sis kuj muab cov neeg siv nrog cov txheej txheem kev yuav khoom thiab kev lees paub, txhawb kev sib koom ua ke ntawm cov txheej txheem kev ua haujlwm thiab kev ua haujlwm thoob plaws hauv cov khoom xa tuaj thiab nqes. Raws li cov ntaub ntawv hloov kho txhim kho mus rau kev ua tau zoo, kev ua haujlwm zoo, thiab kev ruaj khov, cov txheej txheem cuam tshuam yuav txuas ntxiv txhim kho, tsav cov cuab yeej tsim khoom thiab kev siv mus rau tus qauv zoo dua, muaj txiaj ntsig zoo, thiab ib puag ncig yav tom ntej.
