Cov khoom epdm yog dab tsi? -Txoj-ntsuas ntawm cov yam ntxwv thiab kev siv ntawm EPDM roj hmab
EPDM (Ethylene-diene Monomer) yog cov roj hmab hluavtaws nrog cov huab cua zoo, thiab yog siv hauv kev tsim kho, tsim kho, electronics thiab lwm yam lag luam. Ua ntej nkag siab txog dab tsi epdm yog tsim los ntawm, nws yog qhov tsim nyog kom nkag siab nws cov qauv molecular thiab cov txheej txheem tsim qauv nyob rau hauv thiaj li yuav to taub zoo dua cov khoom thiab siv.
1. Tshuaj lom neeg sib xyaw ua ke thiab cov qauv molecular ntawm EPDM
EPDM roj hmab tau txais nws lub npe los ntawm nws lub ntsiab Cheebtsam: ethylene, propylene thiab diene monomers. Cov Monomers Form Elastic Polymer chains los ntawm copolymerisation kev tawm tsam. Ethylene thiab propelene muab cov cua sov zoo thiab oxidation tiv thaiv, thaum lub cev muaj kev sib tw los ntawm vulcanisation lossis peroxide, ntxiv kom muaj zog thiab kav ntev ntawm cov khoom siv.
2. Cov yam ntxwv tseem ceeb ntawm EPDM
Vim nws cov tshuaj tshwj xeeb muaj pes tsawg leeg, epdm muaj ntau cov khoom zoo uas ua rau nws sawv ntsug ntawm cov huab cua zoo, uas txhais tau tias nws muaj peev xwm tau txais thaum lub hnub ci rau lub sijhawm ntev Yog tsis muaj deterioration.epdm kuj muaj cov khoom tseem ceeb heev, uas tso cai rau nws tswj nws qhov kev ua tau zoo hauv kev ua haujlwm hnyav uas tsis muaj kev tawg.
Lwm qhov tseem ceeb tseem ceeb yog nws cov tshuaj lom neeg kuj, tshwj xeeb tshaj yog cov acids, alkalis thiab ntau yam kuab tshuaj polar. Yog li ntawd, EPDM feem ntau siv nyob rau hauv cov xwm txheej uas xav tau kev siv tshuaj lom neeg tau ntev, thiab feem ntau ua haujlwm tau ntau zaus ntawm -40 ° C, uas ua rau nws tshwj xeeb siv nyob rau hauv automotive Kev lag luam, xws li cov ntsaws ruaj ruaj, hos radial hoses, thiab lwm yam.
3. EPDM cov ntawv thov hauv ntau yam lag luam
Qhov kev siv dav dav ntawm EPDM yog ntaus nqi rau nws cov versatility thiab cov khoom siv lub cev zoo nkauj. Nyob rau hauv kev lag luam automotive, EPDM feem ntau siv nyob rau hauv kev tsim cov ntsaws ruaj ruaj, qhov rooj ntsaws, cua ntxig wipers thiab hoses radiator thiab hoses radiator hoses. Ua tsaug rau lawv cov cua sov thiab kev tiv thaiv kev tiv thaiv, cov cheebtsam no tau khaws lawv lub sijhawm ntev, txhim kho lub neej ua haujlwm ntawm lub tsheb.
Hauv kev tsim kho kev tsim kho, EPDM tau siv dav hauv ru tsev waterproofing, qhov rooj thiab qhov rai ntsaws ruaj ruaj thiab lwm yam kev thov uas yuav tsum tau lim dej thiab UV tsis kam. Nws cov huab cua zoo tsis kam thiab yoog raws cov qauv kev ruaj ntseg thiab kev sib khi ua tau zoo ntawm cov xov hlau thiab cable, muab cov hluav taws xob ua tau zoo.
4. EPDM ib puag ncig kev tiv thaiv thiab kev txhim kho kom ruaj khov
Hauv cov ntsiab lus tam sim no ntawm kev tiv thaiv kev tiv thaiv ib puag ncig ib puag ncig, EPDM tseem muaj kev tiv thaiv vim nws lub peev xwm kev tiv thaiv ib puag ncig. EPDM yog cov khoom siv rov ua dua tshiab, cov txheej txheem ntau lawm yog cov roj teeb tsawg dua thiab cov khib nyiab, hauv txoj kab nrog kev tiv thaiv niaj puag ncig. Los ntawm kev txhim kho txuas ntxiv ntawm cov txheej txheem ntau lawm, lub zog thiab kev siv nyiaj tau ntawm EPDM kuj tseem raug txo qis, ua rau muaj kev loj hlob ntawm kev lag luam.

Cov khoom epdm yog dab tsi? Nws yog cov khoom siv roj hmab hluavtaws nrog cov kev ua tau zoo thiab ntau yam ntawm cov ntawv thov. With its weather resistance, chemical resistance and environmental friendliness, it plays an important role in various industries. Txawm hais tias muaj kev lag luam hauv tsheb, lossis cov hluav taws xob thiab hluav taws xob thiab EPDM tau dhau los ua cov khoom siv tsis tau yog vim nws qhov kev ua tau zoo tshaj plaws.
