Hauv kev ua cov yas uas muaj zog heev, cov tshuab extruder conical twin screw (CTSEs) tau tshwm sim los ua cov hloov pauv loj, hloov pauv txoj kev uas cov polymers sib xyaw, sib xyaw, thiab sib xyaw ua ke. Cov tshuab no tau teeb tsa tus qauv tshiab rau kev ua tau zoo thiab kev ua haujlwm zoo, daws cov teeb meem ntawm cov ntawv thov uas xav tau ntau thiab txhawb kev lag luam yas mus rau cov ciam teb tshiab ntawm kev tsim kho tshiab. Cov ntawv blog no tshawb nrhiav txog kev hloov pauv ntawm CTSEs, tshawb nrhiav lawv cov peev xwm tshwj xeeb thiab kev hloov pauv paradigm uas lawv coj los rau kev ua cov khoom siv yas sib txawv.
Qhia Txog Lub Hwj Chim ntawm Conical Twin Screw Extruders
Cov CTSEs sib koom cov ntsiab cai tsim qauv yooj yim ntawm cov tshuab extruders ntxaib ntsia hlau (TSEs), siv ob lub ntsia hlau tig rov qab los thauj, yaj, thiab sib tov polymers. Txawm li cas los xij, CTSEs sib txawv lawv tus kheej los ntawm kev koom ua ke nrog lub qhov conical barrel tsim, qhov twg lub qhov txoj kab uas hla maj mam txo qis mus rau qhov kawg ntawm qhov tso tawm. Cov geometry tshwj xeeb no muab ntau qhov zoo uas ua rau CTSEs yog qhov kev xaiv zoo tshaj plaws rau ntau yam kev siv.
Kev Sib Tov thiab Homogenization Zoo Dua
Lub geometry ntawm lub thoob conical txhawb kev sib tov 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 tawm sib npaug ntawm cov khoom thoob plaws hauv cov yaj. Lub peev xwm sib tov zoo no yog qhov tseem ceeb rau kev tsim cov khoom zoo nrog cov khoom zoo thiab kev ua tau zoo sib xws.
Txo Kev Nyuaj Siab ntawm Shear
Qhov kev txo qis ntawm lub thoob qhov loj me txo qhov kev ntxhov siab ntawm cov polymer yaj, txo qhov kev puas tsuaj ntawm polymer thiab txhim kho cov khoom zoo. Qhov no yog qhov tshwj xeeb tshaj yog rau cov polymers uas rhiab heev rau shear uas yooj yim puas tsuaj nyob rau hauv cov xwm txheej shear siab.
Kev Txhim Kho Kev Ruaj Ntseg Yaj
Tus qauv conical ua rau kom yaj ruaj khov, txo qhov kev pheej hmoo ntawm kev tawg thiab ua kom cov txheej txheem extrusion du thiab sib xws. Qhov kev ruaj khov no yog qhov tseem ceeb rau kev tsim cov khoom zoo nrog cov qhov loj me thiab cov khoom nto sib xws.
Kev Siv Tau Ntau Yam Rau Cov Ntawv Thov Uas Xav Tau Ntau
Cov CTSEs zoo heev hauv kev tswj cov tshuaj sib xyaw uas muaj ntau yam, cov polymers uas rhiab heev rau kev txiav, thiab cov polymer sib xyaw ua ke, ua rau lawv zoo tagnrho rau cov ntawv thov uas xav tau kev sib xyaw zoo thiab cov khoom zoo. Cov ntawv thov uas xav tau ntau yam suav nrog:
Kev rwb thaiv tsev hlau thiab cable: CTSEs yog siv dav hauv kev tsim cov hlau thiab cable rwb thaiv tsev ua haujlwm siab, qhov twg kev sib xyaw ua ke thiab kev ruaj khov yaj yog qhov tseem ceeb.
Cov Yas Kho Mob: Lub peev xwm los tswj cov polymers kho mob rhiab heev ua rau CTSEs zoo rau kev tsim cov raj kho mob, catheters, thiab lwm yam khoom siv kho mob.
Cov Yas Tsheb: CTSEs siv rau hauv kev tsim cov yas tsheb, suav nrog lub bumpers, dashboards, thiab cov khoom siv sab hauv, qhov twg lub zog siab thiab kev ruaj khov yog qhov tseem ceeb.
Cov Ntawv Thov Ntim Khoom: CTSEs yog siv los tsim cov yeeb yaj kiab ntim khoom thiab cov thawv ntim khoom ua tau zoo, xav tau cov khoom thaiv zoo dua thiab lub zog kho tshuab.
Kev Sib Xyaws thiab Masterbatching: CTSEs ua tau zoo hauv kev sib xyaw thiab masterbatching, qhov twg kev sib xyaw thiab kev faib tawm ntawm cov khoom ntxiv thiab cov khoom sau yog qhov tseem ceeb.
Xaus lus
Cov tshuab extruder conical twin screw tau hloov pauv txoj kev lag luam ua yas, muab kev sib xyaw ua ke ntawm cov peev xwm uas daws tau cov teeb meem ntawm cov ntawv thov uas xav tau thiab xa cov khoom zoo tshaj plaws. Lawv qhov kev sib xyaw ua ke zoo dua, txo qhov kev ntxhov siab shear, txhim kho kev ruaj khov yaj, thiab kev hloov pauv ua rau lawv yog cov cuab yeej tseem ceeb rau ntau yam kev lag luam. Raws li qhov kev thov rau cov yas ua tau zoo txuas ntxiv mus, CTSEs tau npaj los ua lub luag haujlwm tseem ceeb hauv kev tsim cov yas yav tom ntej, tsav tsheb tsim kho tshiab thiab txhawb nqa kev lag luam mus rau qhov siab tshiab ntawm kev ua tau zoo.
