Fluororubber O-ring Seals tuaj yeem siv rau hauv Internal Combustion Engines
Mar 19, 2023| Cov ntsaws ruaj ruaj lossis cov khoom siv roj hmab siv hauv kev lag luam hauv tsev, xws li hluav taws xob hluav taws xob, hluav taws xob hlau, thiab roj hmab qhov chaw rau lub qhov cub microwave. Cov ntsaws ruaj ruaj lossis cov khoom siv roj hmab siv hauv kev lag luam hluav taws xob xws li khawm xov tooj, kev poob siab absorbers hauv DVDs, thiab sealing rings hauv cable connectors. Sealing rings rau ntau yam khoom nyob rau hauv kev sib cuag nrog tib neeg, xws li lub raj mis dej, haus dej, thiab lwm yam Fluorosilicone roj hmab hydrogenated nitrile sealing nplhaib Qhov zoo ntawm fluorosilicone roj hmab fluorosilicone roj hmab O-ring yog dab tsi? Qhov kub thiab txias ntawm fluorosilicone roj hmab O-ring Daim ntawv thov fluorosilicone roj hmab O-ring muaj qhov kub thiab txias elasticity thiab tuaj yeem siv rau cov roj thiab cov roj uas muaj ntxhiab hydrogen ntxhia. Nws yog feem ntau siv nyob rau hauv kev sib cuag nrog lub dav hlau xyaw thiab automotive fuels, feem ntau cov kuab tshuaj, thiab cav roj, tshwj xeeb tshaj yog nyob rau hauv lub aerospace kev lag luam.
Viton O-ring seals yog dav siv nyob rau hauv lub teb ntawm diesel locomotives, tsheb, tsheb laij teb, siv machinery, tshuab cuab yeej, thiab ntau yam hydraulic thiab pneumatic Cheebtsam. Lawv tuaj yeem ua lub luag haujlwm ruaj khov, rov ua dua, thiab tig lub luag haujlwm, suav txog ntau dua 50 feem pua ntawm cov khoom siv kho tshuab. Thaum tshav kub kub tsis kam yog superior rau silicone roj hmab, thiab muaj cov tshuaj tiv thaiv zoo heev. Qhov zoo: Nws tuaj yeem tiv taus qhov kub ntawm 250 degree, thiab tiv taus cov roj thiab cov kuab tshuaj feem ntau. Tshwj xeeb tshaj yog, tag nrho cov acids, aliphatic hydrocarbons, aromatic hydrocarbons, thiab tsiaj thiab zaub roj muaj qhov tsis zoo. Nws tsis pom zoo siv rau hauv ketones, qis molecular hnyav esters, thiab cov khoom sib xyaw uas muaj nitrate.
Fluorine roj hmab O-ring (FVMQ) CH3 (Si-O) Molecular qauv ntawm fluorosilicone roj hmab O-ring (CH2CH2CF3-60 ~ 177 degree ). Nyob rau hauv qhov kub thiab txias, qhov ziab kub yog 232 degree, thiab qhov hardness ntau ntawm O-ring yog nruab nrab ntawm A45 thiab 80 degrees Shore. Fluorosilicon O-ring xim rau tsheb, locomotives, diesel xyaw, thiab roj systems. Lub sealing ntawm cov nroj tsuag tshuaj yog resistant rau huab cua thiab ozone; Tsis zoo txias tsis kam. Dab tsi yog qhov dav dav dav rau kev siv- Qhov kub ntawm 20 txog 250 degree . Cov mis tshwj xeeb, tuaj yeem tiv taus qhov kub thiab txias txog li - 40 degree .
