Buna-N, kuj huNitrile Roj Hmab (NBR)los yogAcrylonitrile -Butadiene Roj Hmab, yog lub siab -kev ua tau zoo hluavtaws elastomer paub txog nws:
- Zoo heev roj & roj kuj
- Muaj zog mechanical zog
- Kev ua haujlwm ruaj khov sealing
- Tus nqi -kev tsim khoom zoo
Nws yog ib qho ntawmfeem ntau siv elastomersnyob rau hauv kev lag luam sealing thiab yog mus- rau cov ntaub ntawv rauNBR O-rings, hydraulic seals, gaskets, roj system Cheebtsam, thiabindustrial roj hmab qhov chaw.
NBR yog tsim los ntawm polymerizingAcrylonitrile (ACN)nrogbutadiene.
Cov ntsiab lus ACN feem ntau yog los ntawm18% mus rau 50%, thiab qib ntawm ACN txiav txim siab cov khoom siv ua haujlwm:
- Siab dua ACN → Cov roj ua haujlwm zoo dua, qis dua
- Qis ACN → Kev hloov pauv zoo dua, txo cov roj ua haujlwm
Buna-N cov khoom tuaj yeem hloov kho los ntawmsulfur kho, peroxide kho, thiab kev cai compounding kom tau raws li cov kev cai tshwj xeeb.
Cov yam ntxwv tseem ceeb muaj xws li:
- Qhov zoo tshaj plaws tiv thaiv roj av & hydrocarbons
- Lub zog tensile zog (txog 20 MPa nyob ntawm qib)
- Zoo abrasion & hnav tsis kam
- Ntug A hardness feem ntau40–90
- Qhov kub thiab txias:-30℃rau +120 degree

Koj tuaj yeem paub NBR los ntawm:
- Muaj zog tiv taus roj thiab roj
- Nyuaj tab sis saj zawg zog
- Feem ntau yog xim dub lossis grey tsaus
- Me ntsis tsis hnov tsw thaum hlawv
- "NBR," "Buna-N," lossis "NB" cov cim ntawm kev lag luam O-rings thiab gaskets
Cov kws tshaj lij feem ntau lees paub NBR los ntawm kev ntsuas hnyav lossis tshuaj xyuas cov ntaub ntawv pov thawj.
Vim li cas NBR O-rings yeej tswj kev lag luam sealing?
- Zoo heev roj & roj kuj
- Siab tensile zog & abrasion kuj
- Nqis thiab nqi -zoo rau kev tsim khoom loj
- Dav hardness ntau (40-90 Ntug A)
- Zoo compression teeb → ruaj khov sealing kev ua tau zoo
- Yooj yim rau pwm rau kev cai gaskets & seals
Qhov no ua rau Buna-N tshwj xeeb tshaj yog txaus nyiam rau loj- ntim cov neeg yuav khoom thiab OEM cov chaw tsim khoom.
Txawm hais tias nws muaj zog, Buna-N muaj qee qhov tsis zoo:
- Tsis zoo ozone, UV, thiab huab cua tsis kam
- Tsis haum rau muaj zog oxidizers
- Kev txwv tsis pub ua rau ketones, esters, thiab muaj ntxhiab hydrocarbons
- Tsis zoo rau siab - qhov kub thiab txias (siab tshaj 120 degree)
- Kev tiv thaiv dej tsis zoo; tsis tsim nyog rau lub sij hawm ntev - chav raug
Kev xaiv cov khoom tsim nyog yog qhov tseem ceeb los txuas lub neej kev sib khi.
Yog-Buna-N tuaj yeem muaj kev nyab xeeb rau cov dej hausthaum formulated kom raug.
Txhawm rau siv hauv nroog, thaj chaw, lossis kev lag luam dej haus, NBR yuav tsum ua rawsNSF / ANSI 61 ntawv pov thawj.
Kev sib xyaw ua ke tuaj yeem kho cov qauv los ua Buna-N ua raws rau:
- Cov tshuab lim dej
