Lub Paj Ntsuab Hniav O O Rings
Hydrogenated Nitrile (HNBR) o-rings, tseem hu ua Highly Saturated Nitrile (HSN), yog ua los ntawm cov hluavtaws polymer uas tau los ntawm saturating ob daim ntawv cog lus hauv nitrile=s butadiene ntu nrog hydrogen. Qhov txheej txheem tshwj xeeb hydrogenation no txo ntau cov hlua ob zaug hauv cov saw hlau tseem ceeb ntawm NBR polymers. Cov txheej txheem no ua rau muaj qhov kub zoo tshaj, ua huab cua sov, tiv thaiv tshuaj lom neeg thiab cov yam ntxwv ntawm HNBR dhau tus qauv Nitrile. HNBR o-rings muaj nyob hauv 70 durometer, 80 durometer, thiab 90 durometer.
O-rings yog cov seals nquag siv hauv ntau cov ntawv thov. Muaj ntau cov khoom siv los ntawm cov O-rings tuaj yeem tsim, thiab cov khoom ntawd cuam tshuam rau txoj kev ib qho ntawm o-ring yuav ua haujlwm. Qee cov ntaub ntawv siv tau ruaj dua, lwm tus siv tau ntau dua. Qee tus tuaj yeem tiv taus kub thiab lwm tus muaj peev xwm tiv taus kua muag.
Vim tias lawv tus nqi qis, kev tsim khoom yooj yim thiab kev teeb tsa, hloov yooj thiab tsis kam mus rau qhov siab, O-rings tau pom lawv txoj hauv kev siv lub tshuab cua txias. OEMs paub xaiv O-rings kom zoo thaum lawv sib sau ua ke cov kab ke, thiab nws yog qhov tseem ceeb thaum hloov lawv tias txoj kev xaiv tsim nyog tau rov ua dua.
Txheem O-rings yog NBR (tseem hu ua Nitrile Roj Hmab, Buna-N, lossis tsuas yog Buna). NBR O-Rings feem ntau ntsws me ntsis thiab yuav ua teeb meem to nrog. Cov O-rings yog haum rau cov laj thawj dav raws li lawv tiv taus cov kua muag thiab ua xeb. Lawv ua haujlwm zoo nyob rau hauv cov ntawv thov uas muaj qhov txwv tsawg tsawg thiab qhov xav tau tiv thaiv (tsis yog A / C!).
Ntau O-rings siv nyob rau hauv hiav txwv thiab kev lag luam tshuab yog ua los ntawm Viton, uas yog fluorocarbon roj hmab uas ua tau zoo tshaj plaws hauv kev siv sealing uas muaj kev txav. Viton O-rings qee zaum muaj xim av, lossis dub nrog lub teeb xiav xiav, lossis xim dub xwb. Txawm hais tias lawv tau siv ntau hauv kev siv tsheb, Viton o-rings TSIS tau tshaj nrog cov tub yees. Koj yuav tsis pom lawv nyob rau hauv ib qho OEM AC system thiab koj yuav tsum tsis txhob siv nws rau qhov hloov pauv. Neoprene O-rings tuaj yeem ntim cov tub yees nyob rau hauv tub yees thiab A / C systems, txawm li cas los xij, vim tias lawv tau sib xyaw nrog cov hlau lead lawv yuav tsum tsis txhob siv tes nquag vim lawv tsis zoo rau tib neeg kev noj qab haus huv.
Hom O-ring zoo dua rau kev siv cua txias yog HNBR uas sawv rau Hydrogenated NBR (qee zaum hu ua Hydrogenated Nitrile, lossis Cov Khoom Siv Hluav Taws Xob Nitrile Roj Hmab, lossis HNB). Qhov sib xyaw ntawm HNBR nrog Cov Ntxhia roj, PAG, POE, R-12, R-134a, R-1234yf yog qhov zoo heev. Lwm qhov zoo dua yog tias nws qhov kub thiab txias yog -22F txog 302F. HNBR yog xim ntsuab tas li, tab sis lawv tuaj yeem dub kuj yog, lossis lwm yam xim.
Thaum koj saib ntawm FJC O-rings thiab o-ring cov khoom siv koj yuav nco ntsoov pom cov lus "Txhua O-Rings yog Cov HNUB Kub Siab HNBR". Cov lus tshaj tawm no qhia txog peb cov kev mob siab rau peb cov neeg siv khoom kawg uas txhua lub xov tooj cua FJC muag yog tsim rau cov tshuab cua txias hauv huab cua thiab raug rau cov tub yees thiab cov roj nplua nyeem.
