Ntuj Roj Hmab
Rho tawm los ntawm looj roj hmab ntoo (xws li cov roj hmab roj hmab (xws li cov roj hmab brazilian), thiab ua los ntawm cov txheej txheem xws li salmification thiab ziab.
Lub ntsiab tivthaiv yog polyisoprene (CIS -1}}}}}}, uas yog rau ntuj polymer sib txuas |.
Cov Roj Hmab Hluav Taws Xob
Ua los ntawm cov khoom siv hluav taws xob dag polymerization ntawm cov khoom siv roj xws li butadiene, styrene, thiab lwm yam.
Hom Hom: Styrene Butadiene Roj Hmab Roj Hmab (SBR), Butadiene Roj Hmab (CR), NBRILE roj hmab (NBR), thiab lwm yam.
Qhov sib txawv ntawm lawv yog raws li nram no:
Ntuj Roj Hmab
Qhov Zoo:siab elasticity, kua muag resistance, nkees tsis kam, tsis tshua muaj cua sov tiam (haum rau kev siv hluav taws xob (haum rau kev siv zog).
Qhov tsis zoo:Cov roj tsis zoo, ozone kuj, kev laus kub tsis kam, thiab yooj yim laus (tiv thaiv cov laus yuav tsum tau ntxiv) .
Cov Roj Hmab Hluav Taws Xob
Qhov Zoo:Cov khoom tshwj xeeb tuaj yeem tau txais los ntawm kev hloov kho tshuaj lom neeg, xws li:
Nitrile Roj Hmab (NBr): Cov roj ua tau zoo heev;
Silicone roj hmab: resistant rau high thiab tsawg kub (-60℃~ 250 degree);
Chloroprene roj hmab (CR): nplaim taws retardant thiab corrosion-resistant .
Qhov tsis zoo:Tag nrho kev ua tau zoo tag nrho (xws li elasticity thiab lub zog) feem ntau tsis zoo li cov roj hmab ntuj, thiab qee yam muaj nqi siab dua {}}
Ntuj Roj Hmab
Hnab log (tshwj xeeb tshaj yog cov hnab looj tes kho mob siab), kev poob siab, khau yas, thiab lwm yam}
Qhov tseem ceeb yuav tsum tau muab rau cov xwm txheej nrog cov kev xav tau zoo .
Cov Roj Hmab Hluav Taws Xob
Xaiv raws li cov yam ntxwv:
Styrene Butadiene roj hmab (SBR): Cov log tsuj, Conveyor Siv;
Butyl Roj Hmab (IIR): Sab Hauv Tub Rog, Ntim Khoom Siv (nrog Airtightness);
Ethylene propylene roj hmab (EPDM): Automotive Sealing strips, huab cua resistant cov ntaub ntawv .
Ntuj Roj Hmab
Cia siab rau tsob ntoo ntoo cog qoob loo cog, tus nqi compressates zoo heev vim muaj pes tsawg, kab tsuag thiab kab mob.
Biodegradable thiab ib puag ncig phooj ywg .
Cov Roj Hmab Hluav Taws Xob
Cov khoom siv raw los ntawm cov roj av, thiab tus nqi yog cuam tshuam los ntawm cov crude roj khw .
Cov pa phem yuav tshwm sim thaum lub sijhawm tsim khoom, thiab qee yam yog qhov nyuaj rau kev txwv .
Cov roj hmab bands ua los ntawm cov roj hmab ntuj muaj cov txiaj ntsig no:
Siab elasticity thiab resilience
Cov molecular saw qauv ntawm ntuj roj hmab (polyisoprene) yog tsis tu ncua, muab kev muaj peev xwm sai sai rau nws thawj lub xeev tom qab ncab .
Haum rau kev rov ncab cov xwm txheej (xws li khi cov khoom, cov plaub hau, thiab lwm yam {{{{{.
01
Muaj zog thiab ruaj khov
Cov kua muag zoo: ntuj roj hmab molecules muaj cov roj hmab muaj zog sib xyaw, ua kom cov roj hmab bands tsawg dua rau cov roj hmab tsawg dua .
Qaug zog tiv: kev ua tau zoo tseem tuaj yeem tswj tau tom qab nquag ncab .
02
Yooj thiab xis nyob thiab xis nyob
Cov roj hmab ntuj muaj cov ntaub ntawv muag thiab xis txaus, tshwj xeeb yog cov tawv nqaij uas nkag mus ncaj qha rau cov tawv nqaij (xws li cov plaub hau sib tw, thiab lwm yam {.
Nws tseem yoog raws tsawg kub .
03
Kev Ua Tau Zoo Tshaj
Cov roj hmab muaj yooj yim sib xyaw nrog cov volcanizing cov neeg sawv cev thiab cov fillers, nrog cov txheej txheem sib dhos siab (hla dhau cov txheej txheem, thiab tus nqi qis dua, thiab tus nqi qis.
Lub zog thiab lub zog ntawm cov roj hmab bands tuaj yeem tswj hwm los ntawm kev kho cov mis .
04
Ib puag ncig ua phooj ywg
Cov roj hmab ntuj roj hmab yog biodegradable thiab muaj lub nra ib puag ncig me me tom qab muab pov tseg .
