HNBR O Ring Properties

Loj: Standard, los yog kev cai ua

Hardness: Feem ntau yog 70 Ntug A, tuaj yeem ua los ntawm 50 txog 90

Kom paub txog HNBR O Ring Properties, peb xav kom nkag siab tias nws los li cas. Hydrogenated Nitrile Butadiene Rubber (HNBR) yog ib qho tshwj xeeb saturated tshwj xeeb elastomer zoo li tus nrog kev pab ntawm hydrogenation ntawm Nitrile Butadiene Rubber (NBR). Piv nrog NBR, HNBR molecular zoo muaj me me los yog tsis muaj cov pa roj carbon ob daim ntawv cog lus. Thaum khaws cov roj ua haujlwm thiab muab tso rau ntawm kev tiv thaiv ntawm NBR, nws kuj tseem muaj qhov sov sov thiab cov pa oxygen tau txais kev laus dua (nws tuaj yeem ua haujlwm ntawm ib puas tsib caug degree rau lub sijhawm ntev), ozone tsis kam, hluav taws xob tsis kam, tshuaj lom neeg ua haujlwm (nws muaj qhov tseeb tsis kam. rau hydrogen sulfide) thiab haum dynamic kev ua tau zoo. Nws yog cov roj hmab tshwj xeeb nrog kev ua tiav zoo.

HNBR O Ring Khoom:

1. HNBR tuaj yeem siv rau hauv qhov chaw ua haujlwm ntawm - 40-180degreerau lub sijhawm ntev, nrog kev ua haujlwm zoo, lub zog siab, zoo heev hnav tsis kam, me me deformation mus tas li, thiab qhov tshwj xeeb ozone kuj thiab hydrogen sulfide kuj.

2. Txawm hais tias hydrogenated nitrile roj hmab yog hydrogenated thiab saturated, nws tseem khaws cov yam ntxwv ntawm thawj nitrile. Nws muaj tensile crystallinity, yog li nws muaj zog heev.

3. Nws muaj cua sov zoo, ozone kuj, huab cua aging kuj thiab tshuaj acid thiab alkali tsis kam.

4. Zoo o tuaj yeem ua rau cov kua dej ua kua (xws li cov roj uas muaj corrosive additives).

5. Cov khoom siv kho tshuab zoo, txawm tias nyob rau hauv qhov kub thiab txias, tseem tuav tau ntau theem.

6. Nws muaj qhov hnav tsis zoo nyob rau hauv cov xwm txheej tsis zoo.

7. Lub zog tensile ntawm vulcanizate yog siab dua li ntawm nitrile roj hmab thiab chloroprene roj hmab, thiab ze rau ntawm carboxyl nitrile roj hmab.

8. Kev tiv thaiv zoo rau cov kua qaub (hydrogen sulfide) ib puag ncig thiab amine / roj sib tov, nrog rau oxidation resistant fuels thiab lubricants.

9. Cov iav hloov pauv kub Tg txawv nrog cov qib ntawm hydrogenation ntawm - 15-40degree, thiab lub brittleness kub yog - 50degree.

Daim ntawv thov ntawm hydrogenated nitrile roj hmab (HNBR):

HNBR yog dav siv nyob rau hauv aerospace, tsheb, oilfield drilling, petrochemical, textile, luam ntawv thiab txawv industries, feem ntau yog siv nyob rau hauv lub tsheb gas ntaus ntawv, tsheb kis tau tus mob txoj siv, drilling shielding cover, roj kom zoo packer roj hmab lub tog raj kheej, submersible twj tso kua mis cable sheath rau tsis tshua muaj siab. qhov dej, tshuab tshuab tiv thaiv, stator lub cev muaj zog rau cov kev taw qhia roj ntau lawm, pab hoses rau offshore roj drilling platforms, ntsaws ruaj ruaj rau aerospace, tank song liner, ua npuas ncauj damping cov ntaub ntawv ntau yam roj hmab foob, hydraulic kav, cua txias sealing khoom, luam ntawv thiab ntaub cots rau nuclear kev lag luam .
