(Cov ntsiab lus piav qhia)fluoroelastomer yog ib copolymer ntawm vinyl fluoride thiab hexafluoropropylene. Nyob ntawm nws cov qauv molecular thiab cov ntsiab lus fluorine, fluoroelastomers muaj cov tshuaj lom neeg sib txawv thiab tsis kub tsis kam.
fluoroelastomer yog ib copolymer ntawm vinyl fluoride thiab hexafluoropropylene. Nyob ntawm nws cov qauv molecular thiab cov ntsiab lus fluorine, fluoroelastomers muaj cov tshuaj lom neeg sib txawv thiab tsis kub tsis kam. Fluoroelastomer yog raws li nws cov nplaim hluav taws zoo heev, huab cua nruj, kub tsis kam, ozone tsis kam, huab cua tsis kam, oxidation tsis kam, ntxhia roj tsis kam, roj tsis kam, hydraulic roj kuj, aromatic kuj thiab ntau cov kuab tshuaj organic paub txog nws cov tshuaj lom neeg.
Kev khiav hauj lwm kub nyob rau hauv zoo li qub sealing yog txwv rau ntawm - 26 ° C thiab 282 ° C. Txawm hais tias nws tuaj yeem siv rau lub sijhawm luv luv ntawm qhov kub ntawm 295 ° C, nws lub neej kev pabcuam yuav luv luv thaum qhov kub siab tshaj 282 ° C. Qhov zoo tshaj plaws kub rau siv nyob rau hauv dynamic foob yog nruab nrab ntawm - 15 ℃ thiab 280 ℃, thiab qhov kub tsis tshua muaj peev xwm ncav cuag - 40 ℃.
Fluorine roj hmab sealing nplhaib kev ua tau zoo
(1) Tag nrho ntawm kev hloov pauv thiab ua kom muaj zog;
(2) Tsim nyog txhua yam muaj zog, suav nrog lub zog nthuav dav, elongation thiab tsim kua muag.
(3) Kev ua haujlwm ruaj khov, nws tsis yooj yim rau o hauv nruab nrab, thiab cov nyhuv thermal contraction (Joule effect) yog me me.
(4) Nws yog ib qho yooj yim rau txheej txheem thiab cov duab, thiab muaj peev xwm tswj tau qhov ntev.
(5) Tsis corrode qhov chaw tiv tauj, tsis ua paug qhov nruab nrab, thiab lwm yam.
Qhov zoo ntawm fluorine roj hmab sealing nplhaib
1. Lub nplhaib sealing yuav tsum muaj kev sib khi zoo hauv kev ua haujlwm siab thiab qee qhov kub thiab txias, thiab tuaj yeem txhim kho kev sib khi ua haujlwm raws li qhov siab nce.
2. Kev sib txhuam ntawm lub nplhaib sib khi thiab cov khoom txav yuav tsum yog me me, thiab qhov sib txhuam coefficient yuav tsum ruaj khov.
3. Lub nplhaib sealing muaj zog corrosion kuj, tsis yooj yim rau lub hnub nyoog, lub neej ua haujlwm ntev, hnav tsis kam, thiab tuaj yeem them nyiaj rau qee yam tom qab hnav.
4. Cov qauv yooj yim, siv tau yooj yim thiab tuav lub nplhaib sealing, qhov zoo ntawm fluorine roj hmab sealing nplhaib yog dab tsi los ua kom lub nplhaib sealing muaj lub neej ntev.
O-ring tsim txiav txim siab siv cov khoom siv
O - zoo li lub nplhaib sealing yog tsim rau kev teeb tsa ntawm ntau yam khoom siv kho tshuab, thiab ua lub luag haujlwm sib khi hauv lub xeev zoo li qub lossis txav mus rau hauv qhov ntsuas kub, siab, thiab cov kua thiab roj sib txawv. Ntau hom kev foob yog siv dav hauv cov cuab yeej siv tshuab, nkoj, tsheb, tsheb, khoom siv aerospace, metallurgical machinery, chemical machinery, engineering machinery, engineering machinery, build machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, thiab ntau yam cuab yeej thiab meters. keeb.
