Raws li cov khoom siv tseem ceeb hauv kev ua cov khoom siv polymer, cov ntsia hlau extruders ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv ntau qhov kev lag luam vim lawv txoj haujlwm tsis tu ncua, kev ua haujlwm siab, thiab cov txheej txheem muaj zog. Lawv lub luag haujlwm tseem ceeb yog los hloov cov khoom siv los yog hmoov nplej rau hauv lub xeev tsis sib xws los ntawm kev sib hloov ntawm cov ntsia hlau thiab cov cua sov thiab cua txias ntawm lub thoob, thiab tom qab ntawd txuas ntxiv extrude rau hauv cov txheej txheem kom tau raws li qhov xav tau ntawm cov khoom sib txawv.
Hauv kev lag luam plastics, ntsia hlau extruders yog ib qho ntawm cov khoom siv tseem ceeb tshaj plaws. Lawv tau siv dav hauv kev tsim cov kav dej, nplooj ntawv, profiles, zaj duab xis, thiab cable coatings. Nrog kev sib txawv tuag thiab cov cuab yeej pabcuam sib txuas ua ke, tib lub tshuab tuaj yeem hloov pauv cov lus qhia ntau lawm, txhim kho ntau yam thiab kev lag luam ntawm cov kab ntau lawm. Hauv kev hloov pauv ntawm granulation, ntsia hlau extruders tuaj yeem sib xyaw, sau, ntxiv dag zog, lossis ntxiv cov khoom siv ntxiv rau cov khoom siv raw los npaj cov khoom siv hloov kho uas ua tau raws li cov khoom siv tshwj xeeb, tiv thaiv tshav kub, lossis huab cua tsis kam, muab siab - cov ntaub ntawv zoo rau cov khoom qis.
Kev lag luam roj hmab kuj tso siab rau cov ntsia hlau extruders rau preforming roj hmab tebchaw thiab npaj preforms ua ntej nruam vulcanization. Nws qhov chaw tswj tau qhov kub thiab txias ua haujlwm pab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhaws thiab vulcanization hauv cov khoom siv roj hmab, txo cov npuas thiab qhov tsis xws luag, thiab txhim kho qhov seem stability ntawm semi{1}} cov khoom tiav. Nyob rau hauv cov tshuaj fiber ntau lawm, ntsia hlau extruders tuaj yeem extrude molten polymers los ntawm spinnerets rau hauv fiber ntau dopes, uas yog ces txias thiab stretched rau polyester, nylon, thiab lwm yam filaments los yog staple fibers, txhawb txoj kev loj hlob ntawm textiles thiab industrial textiles.
Ntsia hlau extruders kuj muaj nyob rau hauv cov zaub mov thiab tshuaj industries. Hauv kev ua zaub mov, lawv tuaj yeem siv rau puffing, texturing, thiab kev hloov pauv ntawm cov hmoov txhuv nplej siab los tsim cov khoom noj txom ncauj, cov hmoov muaj zog, thiab lwm yam khoom. Hauv kev lag luam tshuaj, lawv tau siv rau kev ua kom tsis tu ncua reactive extrusion ntawm hluavtaws resins, masterbatches, thiab tshwj xeeb polymers, simplifying txheej txheem thiab txhim kho cov khoom sib xws. Tsis tas li ntawd, hauv cov khoom siv hauv tsev thiab kev rov ua dua ib puag ncig, cov ntsia hlau extruders tuaj yeem ua cov khoom siv rov ua dua tshiab thiab ntoo- cov khoom siv yas, ua rau muaj peev txheej rov ua dua tshiab thiab kev tsim ntsuab.
Yog vim li cas cov ntsia hlau extruders tuav lawv txoj haujlwm tseem ceeb hauv kev hla - kev lag luam daim ntawv thov yog los ntawm kev tswj hwm ntawm lawv cov txheej txheem tsis ua haujlwm thiab lawv cov kev hloov pauv mus rau cov txheej txheem nyuaj. Los ntawm kev hloov cov ntsia hlau sib txuas, kho qhov kub thiab txias profiles, thiab optimizing tuag tsim, lawv muaj peev xwm daws tau ntau yam kev cov nyom, los ntawm qis - viscosity kua mus rau cov khoom sib xyaw ua ke. Nrog rau kev txhim kho kev tsim khoom ntse thiab lub zog-txuag thev naus laus zis, lawv daim ntawv thov tau nthuav dav ntxiv, muab cov kev daws teeb meem zoo thiab ruaj khov rau kev lag luam niaj hnub tsim.
