Cov geometry tshwj xeeb no txhawb kev sib xyaw thiab kev sib xyaw ua ke ntawm cov polymer sib xyaw, cov khoom ntxiv, thiab cov khoom sau, kom ntseeg tau tias muaj kev faib cov ntaub ntawv sib xws thoob plaws hauv kev yaj.
Cov txiaj ntsig ntawm Conical Twin Screw Extruders:
Kev Sib Tov Zoo Dua thiab Kev Sib Koom Ua Ib Homogenization: CTSEs ua tau zoo heev ntawm kev tsim cov khoom zoo nrog cov khoom zoo thiab kev ua tau zoo sib xws, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau kev sib xyaw zoo dua.
Txo Kev Nyuaj Siab Thaum Hlais: Tus qauv tsim conical txo qhov kev nyuaj siab thaum hlais cov polymer yaj, tiv thaiv kev puas tsuaj ntawm cov polymer thiab ua kom cov khoom zoo, tshwj xeeb tshaj yog rau cov polymers uas rhiab heev thaum hlais.
Kev Ruaj Ntseg Zoo Dua: CTSEs txhim kho kev ruaj ntseg ntawm cov khoom yaj, txo qhov kev pheej hmoo ntawm kev tawg ntawm cov khoom yaj thiab ua kom muaj cov txheej txheem extrusion du thiab sib xws, tseem ceeb rau kev tsim cov khoom nrog cov qhov loj me thiab cov khoom nto sib xws.
Kev Siv Tau Ntau Yam Rau Cov Ntawv Thov Uas Xav Tau Ntau: CTSEs tswj cov khoom sib xyaw uas muaj cov khoom puv nkaus, cov polymers uas rhiab heev rau kev txiav, thiab cov polymer sib xyaw ua ke, ua rau lawv haum rau cov ntawv thov uas xav tau ntau xws li kev rwb thaiv tsev hlau thiab cable, cov yas kho mob, cov yas tsheb, kev ntim khoom, thiab kev sib xyaw/masterbatching.
Cov Tshuab Extruder Ib Leeg: Yooj Yim thiab Siv Nyiaj Tau Zoo
Cov tshuab extruder ib lub ntsia hlau (SSEs) sawv cev rau lub zog ua haujlwm ntawm kev lag luam ua yas, muab cov kev daws teeb meem yooj yim thiab pheej yig rau ntau yam kev siv. Lawv tus qauv tsim muaj ib lub ntsia hlau tig hauv lub thoob cylindrical, xa, yaj, thiab ua cov polymer.
Cov txiaj ntsig ntawm Ib Leeg Extruders:
Tsim thiab Ua Haujlwm Yooj Yim: SSEs muab kev tsim thiab ua haujlwm yooj yim, ua rau lawv yooj yim rau kev saib xyuas thiab tsis tshua muaj kev puas tsuaj.
Kev Siv Nyiaj Tau Zoo: SSEs feem ntau pheej yig dua li CTSEs, tshwj xeeb tshaj yog rau cov ntawv thov uas tsis tas yuav sib tov lossis tuav cov ntaub ntawv nyuaj.
Haum Rau Kev Ua Haujlwm Yooj Yim: SSEs ua tau zoo ntawm cov haujlwm ua polymer yooj yim xws li pelletizing, compounding, thiab tsim cov profile yooj yim, ua rau lawv haum rau cov ntawv thov uas tsis kim.
Xaiv Cov Extruder Zoo: Ib Qho Teeb Meem ntawm Daim Ntawv Thov thiab Kev Xav Tau
Qhov kev txiav txim siab ntawm lub tshuab extruder conical twin screw (CTSE) thiab lub tshuab extruder ib lub ntsia hlau (SSE) nyob ntawm qhov kev thov tshwj xeeb thiab cov kev xav tau ua tiav. Rau cov ntawv thov uas xav tau kev sib xyaw zoo dua, txo qis kev ntxhov siab shear, txhim kho kev ruaj khov ntawm yaj, thiab muaj peev xwm tswj cov ntaub ntawv nyuaj, CTSEs yog qhov kev xaiv zoo tshaj plaws. Txawm li cas los xij, rau cov haujlwm ua tiav yooj yim thiab cov ntawv thov uas tsis tshua muaj nqi, SSEs muab kev daws teeb meem zoo thiab pheej yig.
Xaus Lus: Kev Taw Qhia Txog Extruder Landscape
Kev xaiv ntawm lub tshuab extruder conical twin screw (CTSE) thiab lub tshuab extruder ib lub ntsia hlau (SSE) tsis yog ib qho kev txiav txim siab uas haum rau txhua tus. Ua tib zoo soj ntsuam qhov kev siv tshwj xeeb, cov kev xav tau ua tiav, thiab cov kev txwv nyiaj txiag kom txiav txim siab hom extruder uas tsim nyog tshaj plaws. Rau cov ntawv thov uas xav tau kev sib xyaw zoo, cov khoom zoo, thiab lub peev xwm los tswj cov ntaub ntawv nyuaj yog qhov tseem ceeb, CTSEs tshwm sim ua qhov kev xaiv meej. Txawm li cas los xij, rau cov haujlwm ua tiav yooj yim thiab cov ntawv thov uas tsis tshua muaj nqi, SSEs muab cov kev daws teeb meem uas siv tau thiab pheej yig.
