Taw qhia rau EPDM Extrusion
EPDM extrusion tshuabyog cov txheej txheem tsim khoom uas tsim tawmncua ntev ntawm kev cai -zoo li tus roj hmab profilesua los ntawmEPDM (Ethylene Propylene Diene Monomer) roj hmab. EPDM yog ib qho hluavtaws elastomer paub txog nws qhov tshwj xeebhuab cua tsis kam, yooj, thiab durability, ua rau nws zoo tagnrho rausealing, cushioning, thiab vibration absorptiondaim ntawv thov.
Los ntawm extrusion, EPDM tuaj yeem hloov mus rau hauvqhov rooj ntsaws ruaj ruaj, qhov rais profiles, gaskets, automotive trims, hoses, thiab lwm yam complex profilesnrog sib npaug hla-sections. Kev sib xyaw ua ke ntawm EPDM cov khoom siv thiab cov txheej txheem extrusion ua rau muaj ntau yam thiab tus nqi -kev sib khi zoo tsim nyog rau kev lag luam thiab kev lag luam.
EPDM Extrusion txheej txheem
EPDM extrusion muaj ob peb kauj ruam tseem ceeb los hloov cov roj hmab nyoos rau hauv siab -kev ua tau zoo profiles:
1. Kev sib xyaw ua ke
Raw EPDM roj hmab yog tov nrogfillers, stabilizers, curing agents, colorants, thiab lwm yam additives. Cov kauj ruam no tso cai rau cov tuam ntxhab kho cov roj hmabhardness, elasticity, UV tsis kam, thiab tshuaj tiv thaivraws li daim ntawv thov npaj.
2. Extrusion
Cov roj hmab compounded yog pub rau hauv ib qhoextruder, qhov twg cua sov thiab siab yuam nws los ntawm akev cai tuag. Tuag txiav txim qhovpuab thiab hla-sectionntawm EPDM profile, tso cai rau cov geometry complex rau tshwj xeeb sealing yuav tsum tau.
3. Vulcanization (Curing)
Tom qab extrusion, qhov profile yogvulcanizedlos ntawm cua sov, chav, los yog dej kub. Vulcanization tsimhla- txuas hauv cov saw hlau polymer, muab EPDM roj hmabtxhua yam muaj zog, elasticity, thiab ntev - lub sij hawm stability.
4. Txiav thiab ua tiav
Cov extruded profiles raug txiav raukev cai ntev. Xaiv cov txheej txheem xws lidaim ntaub nplaum rov qab, daim ntaub nplaum, lossis ua npuas dej hauv ob sab phlutuaj yeem ua tau raws li cov neeg siv khoom xav tau.
Cov txheej txheem no xyuas kom meej tiasEPDM extrusion muaj cov khoom zoo, qhov ntev, thiab kev ua tau zootshaj loj ntau lawm khiav.
Lub cev thiab cov cuab yeej cuab tam ntawm EPDM Extrusion
EPDM extrusion yog khoom plig rau lawv cov kev sib xyaw ua keyooj, durability, thiab huab cua tsis kam. Cov yam ntxwv ntawm lub cev muaj xws li:
| Khoom | Chav tsev | Tus nqi |
|---|---|---|
| Hardness (Shore A) | – | 45–70 |
| Tensile zog | MPa | Ntau dua lossis sib npaug li 8 |
| Elongation ntawm Break | % | Ntau dua lossis sib npaug li 250 |
| Compression teeb (70 degree, 24h) | % | Tsawg dua los yog sib npaug li 25 |
| Qhov kub thiab txias | degree | -40 rau +120 |
| Qhov ntom | g/cm³ | 1.1–1.3 |
| Ozone & UV Resistance | – | Zoo heev |
| Kev nqus dej | % | Tsawg dua los yog sib npaug li 0.5 |
| Huab cua Resistance | – | Zoo heev |
Nco tseg: Cov khoom tuaj yeem raug kho raws li qhov tshwj xeeb profile, hardness, lossis cov ntawv thov.
Cov txiaj ntsig tseem ceeb ntawm EPDM Extrusion
EPDM extrusion muaj ntau yam txiaj ntsig uas ua rau lawv xaiv zoo dua piv rau PVC lossis silicone roj hmab profiles:
1. Huab cua tshwj xeeb thiab UV tiv taus
EPDM tuav nws elasticity thiab sealing zog hauvhuab cua sab nraum zoov, suav nrogUV raug, ozone, nag, thiab huab cua hnyav.
2. Kev kub siab dav
EPDM extrusion ua hauj lwm ntseeg tau nyob rau hauvkub ntawm -40℃mus rau +120 degree, ua rau lawv haum rau ob qho tib si txias thiab kub ib puag ncig.
3. Ntev -Lub Sij Hawm Ntev
Cov extrusion no tiv taustawg, laus, shrinkage, thiab deformation, kom ntseeg tau ntau xyoo ntawm kev ua haujlwm zoo ib yam.
4. Flexibility thiab Custom Shapes
EPDM tuaj yeem raug extruded rau hauvcomplex profiles, suav nrog hollow chambers, T-cov duab, thiab cov gaskets tshwj xeeb rau lub qhov rooj, qhov rais, tsheb, lossis tshuab.
5. Tshuaj tiv thaiv
EPDM tiv tausme ntsis acids, alkalis, tshuaj ntxuav, thiab dej, ua rau nws zoo tagnrho raucov ntawv thov kev lag luam.
6. Tus nqi -Kev ua tau zoo
Piv rau silicone, EPDM yog ntau duakev lag luamrau loj- tej yaam num loj, thaum tseem muabkev ua tau zoo heevthiabkev nyob ntev.
