Dab tsi yog Cov Khoom Siv Zoo Tshaj Plaws rau Roj Resistant Gaskets?
Nov 25, 2023
Qhov kev xaiv ntawm cov khoom siv rau cov roj-resistant gaskets nyob ntawm seb yam xws li hom roj los yog lubricant koom nrog, kub, siab, thiab cov kev thov tshwj xeeb. Ntau cov ntaub ntawv feem ntau yog siv los tsim cov roj-resistant gaskets. Nov yog qee cov ntaub ntawv zoo tshaj plaws rau roj-resistant gaskets:
Nitrile (NBR):Nitrile roj hmab yog dav siv rau roj-resistant gaskets. Nws muaj kev tiv thaiv zoo rau ntau yam roj, roj, thiab lubricants. Nitrile yog tus nqi-zoo thiab haum rau ntau qhov kub thiab txias.
Fluoroelastomers (Viton):Fluoroelastomers, feem ntau paub los ntawm lub npe lag luam Viton, muaj kev tiv thaiv zoo tshaj plaws rau ntau yam tshuaj, suav nrog ntau cov roj thiab roj. Lawv tsim nyog rau cov ntawv thov kub thiab muab cov khoom sib khi zoo heev.
Neoprene (CR):Neoprene paub txog nws cov tsis kam rau roj, tshuaj, thiab huab cua. Nws feem ntau yog siv rau hauv gaskets rau daim ntawv thov uas muaj roj thiab roj. Neoprene muaj qhov hloov tau zoo thiab ua haujlwm tau zoo ntawm qhov kub nruab nrab.
EPDM (Ethylene Propylene Diene Monomer):EPDM yog cov roj hmab ntau yam uas muab kev tiv thaiv zoo rau dej, chav dej, thiab qee cov roj. Txawm hais tias nws yuav tsis yog roj-resistant li Nitrile los yog Fluoroelastomers, EPDM yog haum rau ntau yam kev siv thiab yog tus nqi-zoo.
Aflas:Aflas yog fluoroelastomer uas muaj kev tiv thaiv siab rau ntau yam tshuaj, suav nrog roj thiab roj. Nws ua tau zoo ntawm qhov kub thiab txias thiab feem ntau siv rau hauv kev thov kev lag luam.
Silicone:Silicone roj hmab paub txog nws qhov yooj yim thiab ua haujlwm rau qhov kub thiab txias. Txawm hais tias nws yuav tsis muaj tib theem ntawm cov roj kuj zoo ib yam li lwm cov ntaub ntawv, nws tseem tuaj yeem tsim nyog rau qee yam kev siv uas muaj roj thiab lubricants.
PTFE (Polytetrafluoroethylene):PTFE yog cov khoom siv ntau yam paub txog nws cov tshuaj tiv thaiv. Nws yog feem ntau siv rau gaskets nyob rau hauv daim ntawv thov uas raug rau cov roj, fuels, thiab aggressive chemicals yog ib qho kev txhawj xeeb. PTFE gaskets yog tsim rau cov ntawv thov kub.
Nws yog ib qho tseem ceeb uas yuav tau xav txog cov kev cai tshwj xeeb ntawm koj daim ntawv thov thiab hom roj los yog roj nplua nyeem thaum xaiv cov khoom siv roj-resistant gaskets. Kev ntsuam xyuas cov khoom siv gasket qhov kev sib raug zoo nrog cov roj lossis cov kua dej tshwj xeeb yog pom zoo kom ua kom pom kev ua haujlwm zoo thiab ua haujlwm ntev.
