Yuav Ua Li Cas HNBR Cov Khoom Siv Tsim thiab Hloov Kho
HNBR O-rings yog cov ntsaws ruaj ruaj uas muaj kev ua haujlwm siab uas tau siv ntau hauv kev lag luam. HNBR yog ib qho kev hloov kho tshiab (xws li hydrogenated, yog li H) version ntawm Nitrile Rubber (NBR). hydrogenated, li no H - variation ntawm nitrile butadiene roj hmab (NBR). Cov txheej txheem saturates cov butadiene ntu ntawm NBR nrog hydrogen, txo tus naj npawb ntawm ob daim ntawv cog lus hauv NBR thiab tsim cov khoom muaj zog uas zoo dua khaws nws cov khoom tseem ceeb.
HNBR O-ringsmuaj superior tiv thaiv tshav kub, ozone, tshuaj, puas, roj, thiab roj thiab txhim kho txhua yam yam ntxwv.
Zoo li lwm cov khoom siv o-ring thiab sealing khoom, HNBR tuaj yeem hloov kho raws li kev lag luam thiab daim ntawv thov los ntawm kev kho cov ntsiab lus ntawm acrylonitrile (ACN) - monomer siv hauv kev tsim cov yas. Rau HNBR, ACN cov ntsiab lus feem ntau yog teem ib ncig ntawm 36%. Cov ntsiab lus qis ACN ua rau muaj kev ua tau zoo dua hauv cov ntawv thov kub qis, tab sis cov khoom poob qee qhov tsis kam rau cov roj thiab cov roj nplua nyeem. Kev nce tus nqi ntawm ACN muaj qhov sib txawv.

Kev lag luam thiab kev siv qhov twg HNBR O-Rings Zoo heev
HNBR o-rings muaj nyob rau hauv ntau qhov kev lag luam thiab kev siv uas suav nrog roj thiab roj, tsheb, aerospace, kev tsim khoom, kev ua tshuaj lom neeg, thiab lwm yam.
Ntawm cov no, kev lag luam tsheb yog ib qho ntawm cov neeg siv loj tshaj plaws ntawm HNBR ua tsaug rau nws lub zog thiab muaj peev xwm tswj tau nws cov khoom cua sov-, tshuaj lom neeg, thiab roj-resistant rau lub sijhawm ntev. Ntau yam khoom siv hauv tsheb yog tsim los ntawm HNBR xws li txoj siv sia thiab hoses, thaum ntau lwm tus siv HNBR o-rings thiab gaskets hauv lawv cov kev tsim kho (xws li lub cav, cua txias, ncua kev kawm ntawv, thiab kis tau tus mob tag nrho siv HNBR seals).
Hauv kev lag luam roj thiab roj, HNBR o-rings thiab cov ntsaws ruaj ruaj tau muab tso rau ua haujlwm qhov twg lwm cov ntaub ntawv yuav tsis ua. Hauv cov ntawv thov siv siab xws li cov roj zoo drilling thiab qhov chaw sib sib zog nqus uas muaj kev kub ntxhov thiab kub, HNBR tuav nws txoj kev tiv thaiv txawm tias muaj kev cuam tshuam zoo ib yam rau cov roj, roj, thiab roj nplua nyeem siv hauv cov cuab yeej tshawb nrhiav.
HNBR qhov kev tiv thaiv rau huab cua thiab ozone (tshaj tus qauv NBR) thiab chav ua haujlwm kuj tseem siv tau ntawm no, vim tias kev tshawb nrhiav roj tau tshwm sim hauv qee qhov chaw hauv ntiaj teb hnyav tshaj plaws thiab rau lub sijhawm ntev.
Qhov twg HNBR tsis yog qhov kev xaiv khoom zoo tshaj plaws
Thaum HNBR O-rings tuaj yeem tiv taus qee qhov kev siv nyuaj tshaj plaws thiab ib puag ncig uas paub rau tib neeg, muaj ntau yam ntaub ntawv thiab qhov xwm txheej uas lawv cov yam ntxwv thiab cov khoom yuav tsis xa cov kev ua haujlwm xav tau.
Piv txwv li, hauv kev kho mob thiab kev lag luam tshuaj, HNBR yuav tsum tsis txhob siv vim hais tias cov ntsiab lus ntawm nws yog tshuaj lom, xws li ACN. Thaum HNBR tuaj yeem siv rau hauv qee yam khoom siv kho mob xws li kev nqa tus neeg mob thiab txawm tias cov khoom siv tes ua haujlwm, cov ntawv thov uas yuav raug ntxuav thiab nquag tu lossis cov uas muaj qhov kub siab tshaj qhov max compound peev xwm ntawm 350ºF / 180ºC yuav tsum siv lwm yam ntaub ntawv.
HNBR tsis sib xws nrog cov ntawv thov cuam tshuam nrog qhov tseem ceeb thiab ntev raug rau UV teeb. Piv txwv li, cov tshuaj tua kab mob rau cov cua thiab dej huv yuav tsum tsis txhob siv HNBR o-rings thiab cov ntsaws ruaj ruaj. Polar cov kuab tshuaj xws li ketones, esters, thiab ethers muaj nyob rau hauv cov tshuaj pleev ib ce thiab xim industries, yog li cov cuab yeej siv los yog tshuab tsim cov khoom no yuav tsis tau txais txiaj ntsig los ntawm HNBR. Thaum nws los txog rau acetic acids (siv nyob rau hauv kev tsim inks thiab dyes thiab txawm nyob rau hauv kev ua liaj ua teb) thiab hydrochloric acid (nyob rau hauv steel ntau lawm thiab qab zib ua), HNBR yuav tsis muaj peev xwm tswj nws cov kev ua tau zoo.
