Khoom Description
Pib kis tau tus mob NBR foob
Nws yog feem ntau siv NBR (nitrile butadiene roj hmab) cov ntsaws ruaj ruaj hauv tsheb tsis siv neeg kis. NBR roj hmab muaj cov roj ua haujlwm zoo heev, lub zog txhua yam, thiab hnav tsis kam, ua rau nws yog qhov kev xaiv zoo tshaj plaws hauv ntau lub tsheb tsav tsheb.
Nyob rau hauv tsheb tsis siv neeg kis tau tus mob, NBR ntsaws ruaj ruaj yog feem ntau siv nyob rau hauv cov nram qab no qhov chaw:
Roj foob: NBR roj foob yog siv dav hauv cov khoom tseem ceeb xws li cov khoom siv nkag, cov zis tawm, thiab hydraulic system ntawm kev sib kis tsis siv neeg. Cov roj ntsaws ntsaws ntsaws ntsaws ntsaws ruaj ruaj thiab cov roj hydraulic, tiv thaiv cov dej ntws thiab ua kom lub cev ua haujlwm zoo.
O-rings: NBR O-rings feem ntau yog siv rau hauv cov khoom sib txuas xws li hydraulic tswj valve lub cev, sensors, thiab cov pob qij txha ntawm kev sib kis tsis siv neeg. Lawv muab ib qho kev ruaj ntseg foob tiv thaiv cov kua thiab roj.
Lub tshuab nqus tsev vacuum seals: Hauv kev sib kis tsis siv neeg, qee lub tshuab (xws li lub tshuab nres nres) yuav xav tau kev siv lub tshuab nqus tsev. NBR cov ntsaws ruaj ruaj yog siv los xyuas kom meej tias cov kev sib txuas ntawm cov kav dej nqus tau zoo kaw kom muaj kev ua haujlwm zoo ntawm lub cev.
Qhov zoo ntawm NBR cov ntsaws ruaj ruaj suav nrog kev ua haujlwm zoo rau roj, puas, thiab kub siab (feem ntau nyob ib puag ncig 100 degree). Cov yam ntxwv no ua rau NBR cov ntsaws ruaj ruaj los muab kev ruaj ntseg sealing kev ua tau zoo thiab tuav lub neej ntev kev pab cuam hauv kev ua haujlwm hnyav ntawm tsheb tsis siv neeg kis.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov tshwj xeeb tsis siv neeg kis tau tus mob tsim thiab cov chaw tsim khoom yuav ua rau muaj kev siv lwm yam khoom siv foob hauv qee kis.

Products Performance Description
Pib kis tau tus mob NBR foob
Cov hauv qab no yog qee qhov kev qhia txog kev ua tau zoo
Lub cev muaj zog
Qhov ceev: Qhov ceev ntawm NBR roj hmab feem ntau yog nyob nruab nrab ntawm 1.0-1.2 g / cm³, nrog rau qhov hnyav thiab ntim cov yam ntxwv.
Modulus ntawm elasticity: NBR muaj lub siab modulus ntawm elasticity, tso cai rau nws muab cov khoom zoo sealing thiab elastic rov qab rau hauv daim ntawv thov kis.
tshuaj muaj zog
Roj tsis kam: NBR roj hmab muaj cov roj ua haujlwm zoo heev thiab tuaj yeem tswj hwm kev ua haujlwm zoo hauv ib puag ncig uas nws raug rau lubricating thiab hydraulic roj hauv kev sib kis.
Chemical Resistance: NBR muaj kev tiv thaiv zoo rau cov tshuaj siv tshuaj thiab roj, tab sis yuav raug kev txom nyem los ntawm qee yam tshuaj xws li ketones thiab ester cov kuab tshuaj.
Mechanical cwj pwm
Hnav tsis kam: NBR roj hmab muaj kev hnav zoo thiab tuaj yeem tiv taus qhov kev xav tau ntawm kev sib hloov ceev thiab kev sib txhuam hauv kev sib kis.
Lub zog thiab toughness: NBR muaj cov neeg kho tshuab siab thiab lub zog, tso cai rau nws tswj nws cov duab thiab kev ua tau zoo raws li extrusion thiab deformation tej yam kev mob ntawm kis tau tus mob.
Kev ua tau zoo
Plasticity: NBR roj hmab muaj cov yas zoo thiab tuaj yeem tsim tau rau hauv cov ntsaws ruaj ruaj ntawm ntau yam duab thiab ntau thiab tsawg los ntawm extrusion, compression molding, thiab txhaj tshuaj molding.
Adhesion: NBR roj hmab tau zoo adhesion rau hlau thiab lwm yam ntaub ntawv, kom ntseeg tau ib tug zoo kev twb kev txuas ntawm lub foob thiab ib puag ncig cov khoom.
