Lub tshuab extruder roj hmab sawv cev rau lub hauv paus ntawm kev ua cov polymer, lub tshuab ua tau ntau yam thiab ruaj khov uas tseem ceeb rau kev tsim cov roj hmab sib xyaw ua ntau yam profiles. Nws txoj haujlwm, raws li lub hauv paus ntsiab lus ntawm kev yuam cov khoom siv roj hmab viscoelastic los ntawm lub pwm ntawm cov duab tshwj xeeb, yog qhov yooj yim dag. Txawm li cas los xij, kev tsim kho tom qab nws thiab nws cov yam ntxwv ua rau nws tsis tseem ceeb thoob plaws hauv kev lag luam, los ntawm tsheb mus rau kev tsim kho.
Cov Yam Ntxwv Tseem Ceeb ntawm Cov Roj Hmab Extruders
Cov roj hmab extruders niaj hnub no, feem ntau yog cov qauv ntsia hlau, muaj ntau yam ntxwv uas ua rau lawv siv tau dav:
1. Kev Ua Haujlwm Txuas Ntxiv Mus Thiab Zoo: Tsis zoo li cov txheej txheem ua ke, cov extruders ua haujlwm txuas ntxiv mus, cov khoom siv roj hmab extrusion, txais cov roj hmab sib xyaw (feem ntau yog daim ntawv strip los ntawm lub tshuab sib tov) thiab tso tawm cov qauv tsis tu ncua, sib xws. Qhov no ua kom muaj kev tsim khoom siab, cov khoom zoo sib xws, thiab kev siv cov khoom siv zoo nrog cov khib nyiab tsawg kawg nkaus.
2. Kev Siv Tau Ntau Yam: Los ntawm kev hloov lub taub hau tuag xwb, ib lub tshuab extruder tuaj yeem tsim tau ntau yam duab sib txawv - khoom khov, khoob, lossis ntau yam khoom sib txawv. Qhov no suav nrog cov foob yooj yim, cov khoom siv kho kom zoo nkauj hauv tsheb, cov log tsheb, thiab cov kav dej ntawm ntau txoj kab uas hla.
3. Kev Sib Tov thiab Kev Sib Koom Ua Ke: Tus qauv ntsia hlau, feem ntau nrog cov ntu sib tov lossis cov koob, muab cov zog txiav thiab cov zog nias loj heev. Qhov kev ua no ua rau cov roj hmab sib koom ua ke zoo, faib cov khoom ntxiv xws li carbon dub sib npaug thiab ua kom muaj viscosity thiab cov khoom sib xws thoob plaws hauv extrudate.
4. Kev Tswj Kub thiab Kev Npaj Vulcanization: Lub thoob extrusion tau muab faib ua ntau thaj chaw tswj qhov kub. Qhov no tso cai rau kev tswj hwm qhov kub ntawm cov roj hmab, ua kom cov khoom siv plastifying zoo tshaj plaws rau kev extrusion. Cov extruders niaj hnub no feem ntau sib xyaw nrog cov kab cua kub lossis microwave curing, npaj cov profile rau kev vulcanization tam sim ntawd.
5. Kev Hloov Kho Tau Raws Li Cov Khoom Siv Sib Txawv: Cov tshuab extruder tuaj yeem ua ntau yam roj hmab sib xyaw, los ntawm roj hmab ntuj (NR) thiab styrene-butadiene roj hmab (SBR) mus rau cov polymers tshwj xeeb xws li ethylene propylene diene monomer (EPDM) thiab silicone. Kev hloov kho qhov ceev ntawm lub hau ntswj, qhov kub thiab txias, thiab kev tsim pwm ua raws li cov khoom ntws sib txawv (rheology).
6. Kev Sib Koom Tes Nrog Cov Khoom Siv Hauv Qab: Lub zog tseem ceeb yog nws lub peev xwm ua haujlwm ua lub plawv ntawm cov kab ntau lawm. Nws sib koom ua ke nrog cov tshuab tuag rau cov log tsheb, cov taub hau hla rau cov hlau thiab cov xov hlau, cov tshuab txiav, cov thoob dej txias, thiab cov tshuab vulcanization tas mus li, ua rau muaj kev tsim khoom tag nrho.
Cov Ntawv Thov Tseem Ceeb hauv Kev Lag Luam
Cov yam ntxwv tshwj xeeb ntawm cov roj hmab extruders txhais ua cov ntawv thov tseem ceeb thoob plaws ntau lub sectors:
· Kev Tsim Khoom Siv Log Tsheb: Qhov no yog ib qho ntawm cov ntawv thov tseem ceeb tshaj plaws. Cov tshuab extruders tread tshwj xeeb, feem ntau nrog cov menyuam tuag, tsim cov qauv tread thiab cov qauv sidewall meej. Lwm cov extruders siv rau cov liners sab hauv, cov kab apex, thiab ntau yam roj hmab hauv lub log tsheb. roj hmab extruder tshuab chaw tsim khoom hauv Suav teb, Lub peev xwm los sib koom ua ke sib txawv roj hmab yog qhov tseem ceeb ntawm no.
· Cov Khoom Siv Tsheb: Kev lag luam tsheb vam khom ntau rau cov roj hmab extruded rau cov kab ke kaw (cov foob qhov rooj, cov foob qhov rai, cov foob lub cev tsheb), cov yeeb nkab (cov dej txias, cov cua nkag), khau plua plav, thiab cov khoom dai. EPDM yog qhov tshwm sim ntau heev ntawm no vim nws tiv taus huab cua.
· Kev rwb thaiv tsev thiab txheej txheej ntawm cov hlau thiab cov hlua: Siv lub tshuab crosshead die, cov extruders ua kom cov hlau tooj liab lossis txhuas muaj cov txheej rwb thaiv tsev (piv txwv li, los ntawm EPR, XLPE) thiab cov tsho tiv thaiv sab nraud (feem ntau los ntawm PVC lossis cov roj hmab tsis muaj halogen). Daim ntawv thov no xav tau qhov tseeb heev hauv kev sib sau ua ke thiab tuab.
· Cov Khoom Siv Roj Hmab Dav Dav: Pawg dav dav no suav nrog cov yeeb nkab hydraulic thiab pneumatic, ntau yam yeeb nkab rau kev siv kho mob lossis kev lag luam, cov roj hmab rau cov foob tshuab, cov gaskets tub yees, thiab cov khoom siv khov kho lossis cov ntaub nqus dej rau cov tsev.
· Kev Tsim Kho thiab Kev Tsim Kho Vaj Tse: Cov roj hmab extruded yog siv rau hauv cov pob qij txha nthuav dav rau cov choj thiab cov tsev, cov ntaub qhwv silicone rau cov tshuab textile, cov ntaub thaiv dej tsis pub dej nkag, cov gaskets rau glazing, thiab cov profiles rau cov ru tsev.
· Cov Khoom Siv Rau Cov Neeg Siv Khoom: Cov ntawv thov muaj xws li cov gaskets hauv tsev thiab cov cuab yeej tuav mus rau cov khoom siv kis las thiab cov khau hauv qab.
Xaus lus, lub tshuab extruder roj hmab yog ib qho qauv ntawm kev ua haujlwm zoo, kev tsim khoom tas mus li. Nws cov yam ntxwv ntawm kev ua tau ntau yam, kev tsim khoom tas mus li, thiab kev tswj hwm cov txheej txheem kom meej daws cov teeb meem tseem ceeb ntawm kev tsim cov roj hmab. Raws li kev tshawb fawb txog cov khoom siv tau nce qib thiab kev thov rau cov khoom siv roj hmab nyuaj, kev ua haujlwm siab loj hlob, lub tshuab extruder txuas ntxiv hloov zuj zus - suav nrog kev tswj hwm cov txheej txheem ntse dua, kev tsim cov ntsia hlau siab heev, thiab kev koom ua ke zoo dua nrog cov kab ke downstream. Nws tseem yog, tsis muaj qhov tsis ntseeg, lub tshuab tseem ceeb hauv kev txhais cov roj hmab nyoos rau hauv cov khoom tseem ceeb uas lub neej niaj hnub no thiab kev lag luam vam khom.
