Nitrile (NBR) O-rings feem ntau paub txog lawv cov kev tiv thaiv rau ntau hom roj, suav nrog roj av, diesel, thiab lwm yam khoom siv roj av. Qhov kev tiv thaiv no yog vim muaj cov khoom siv los ntawm Nitrile roj hmab, uas yog tsim los ntawm copolymer ntawm butadiene thiab acrylonitrile. Cov ntsiab lus acrylonitrile hauv Nitrile roj hmab plays lub luag haujlwm tseem ceeb hauv kev muab cov roj thiab roj.
Nitrile O-rings tau dav siv hauv tsheb, aerospace, marine, thiab kev lag luam kev lag luam uas raug rau cov roj ntau. Lawv zoo kaw cov kev sib txuas thiab tiv thaiv cov xau, ua kom muaj kev ncaj ncees thiab kev ua haujlwm ntawm cov kua dej.
Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qib ntawm kev tiv thaiv yuav txawv nyob ntawm qhov tshwj xeeb ntawm cov khoom siv Nitrile thiab hom roj uas nws ntsib. Thaum Nitrile O-rings feem ntau pom muaj qhov ua tau zoo rau feem ntau cov roj, qee cov roj ntsha hnyav lossis cov khoom ntxiv tuaj yeem ua rau cov khoom tsis zoo nyob rau lub sijhawm.
Rau cov ntawv thov tseem ceeb uas cov roj tsis kam yog qhov tseem ceeb, nws raug nquahu kom sab laj nrog cov neeg muag khoom lossis ua qhov kev sib tw sib tw kom ntseeg tau tias cov Nitrile O-rings tau xaiv tau raws li cov cai tshwj xeeb thiab ib puag ncig ntawm daim ntawv thov. Txoj hauv kev zoo tshaj plaws no pab tswj kev ntseeg siab thiab kev nyab xeeb rau lub sijhawm ntev.
