Lub installation ntawm fluorine roj hmab roj ntsaws ruaj ruaj yuav tsum them nyiaj rau cov teeb meem
Ua ntej tshaj plaws, peb yuav tsum them siab rau qhov kev kam rau siab ntawm roj hmab roj hmab roj thiab lub taub hau. Feem ntau, kev ua siab ntev yog ib qho uas tsis paub meej. Kev hloov pauv ua raws li ib txoj cai, namely: Thaum lub qhov taub siab yog tsawg dua los sis sib npaug li 25 hli, FKM roj Seev lub voj voos lees yuav tsum yog 0.1 hli, thaum lub taub ntawm lub taub hau ntawm 25 mus rau 28 hli, verticality kam rau siab yuav tsum tswj nyob rau hauv 0.2 hli, lub xeem yog siab tshaj 80mm ib qhov teeb meem, kam rau siab kom deb li deb tau tshaj tawm hauv 0.3.
Qhov thib ob, yuav tsum tau them nyiaj rau qhov kev sib txuas lus thiab kev sib txuas lus.
Thaum kawg, hauv kev txhim kho ua ntej cov roj hmab foob siv rau hauv cov roj ntub rau ib lub sijhawm, kom tshem tawm cov paug deg. Qhov thib ob yog nyob rau hauv xaiv ntawm fluorine roj hmab roj ntsaws thaum lub di ncauj ntawm cov foob pob zeb yog burr thiab xeb, nyiaj caij nplooj ntoos hlav resilience yog zoo.
Fluorine roj hmab roj khoob taub roj hmab (FPM) kev kub ntxhov siab ua haujlwm zoo heev, thaum 200-250 degrees Celsius tuaj yeem ua haujlwm ntev, FKM Roj Seal ntawm 300 degrees kuj tuaj yeem ua haujlwm luv. Lub zog tensile thiab hardness ntawm fluorine roj hmab txo obviously nrog nce ntawm kub. Qhov txawv ntawm tensile lub zog thiab hardness yog tias, nyob rau hauv 150 degrees, nws txo sai sai nrog nce kub, thiab ntawm 150-260 degrees, nrog qhov nce ntawm kub, FKM roj Seal tus downward sib qeeb yog qeeb.
Fluorine roj hmab roj khoob khoob corrosion resistant performance fluorine rubber (FPM) muaj cov tshuaj tiv thaiv zoo heev. Nws muaj kev ruaj ntseg zoo tiv thaiv cov kua organic, roj roj thiab lubricants, thiab muaj cov tshuaj tua hluavtaws zoo tshaj rau cov organic acids, hydrocarbons, benzene thiab toluene.
Fluorine roj hmab roj ntim cov kua nplaum Tso ciaj saum roj carbon fiber (FKM) yog siv los kaw hauv qab kev kub siab, thiab kev ua kom yuam deformation yog qhov tseem ceeb. Viton-hom fluorine roj hmab yog siv ntau heev, FKM roj Foob thiab nws yog qhov kev txhim kho ntawm nws qhov kev sib hloov ntawm kev sib deev. DuPont nyob rau hauv Tebchaws Asmeskas hauv xyoo 20th xyoo 60-70-xyoo kev cog lus los txhim kho qhov tsis ua haujlwm ntawm cov tshuaj fluorine los ua kom muaj kev sib hloov, FKM Oil Seal tau ua tiav.
Fluorine roj hmab roj khoob mus rau qhov kub thiab txias (low-temperature) fluorine rubber (FKM) yuav tswj tau qhov ntsuas kub ntawm -15 ~ -20 degree, FKM roj Seal nrog cov txo qis, nws lub zog tensile loj zuj zus, thaum kub tsawg tshwm. Thaum lub thickness yog 2MM, qhov kub thiab txias yog 30 degrees thiab thickness yog 1.87MM, nws qhov kub yog 45 degrees, thickness 0.63MM, kub yog-53 degrees, thickness 0.25, kub yog-69 degrees. FKM Oil Seal Cov tshuaj fluorine roj hmab siv kub hnyiab tau me ntsis qis tshaj qhov kub kub.
Fluorine roj hmab roj ruaj ruaj tuaj mus rau kev nyab xeeb kev laus thiab qub ozona-resistant Vitona ntuj cia tom qab 10 xyoo ntawm kev kawm yog tseem txaus siab. Nyob rau hauv lub ozone concentration ntawm 0.01% cua, cov nyhuv ntawm 45 hnub tsis tshwm sim pom kev tawg. Peb cov ntaub ntawv: NBR (NBR) fluorine rubber (VITON) EPDM roj hmab (EPDM) Silicone Rubber (VMQ) Neoprene (CR) Styrene-butadiene (SBR) hydride nitrile (HNBR) thiab ntau hom khoom roj hmab, FKM Roj Cov foob kuj tseem muaj peev xwm muab tau cov nqus tawv tawv $ naj npawb ntawm cov khoom; Cov khoom tseem ceeb ntawm cov roj hmab fluorine
Fluorine roj hmab roj nias ntawm kev kub ntxhov fluorine roj hmab (FPM) ntawm kev kub taub hau ua haujlwm zoo heev, ntawm 200-250 degrees Celsius yuav ua haujlwm ntev, tom 300 degrees kuj tuaj yeem ua haujlwm luv. Lub zog tensile thiab hardness ntawm fluorine roj hmab txo obviously nrog nce ntawm kub. Qhov txawv ntawm tensile lub zog thiab hardness yog tias, nyob rau hauv 150 degrees, FKM roj Seal nws txo sai sai nrog kev kub, thiab ntawm 150-260 degrees, nrog qhov nce ntawm kub, txoj kev downward qeeb.
Fluorine roj hmab roj khoob khoob corrosion resistant performance fluorine rubber (FPM) muaj cov tshuaj tiv thaiv zoo heev. Nws muaj kev ruaj ntseg zoo tiv thaiv cov kua organic, roj roj thiab lubricants, thiab muaj cov tshuaj tua hluavtaws zoo tshaj rau cov organic acids, hydrocarbons, benzene thiab toluene.
. Fluorine rubber Cov roj khoob rau ntawm cov roj ntsha tuaj (Permanent deformation fluoride fluoride) (FKM) siv rau kev sib khib hauv siab, FKM roj Seal thiab kev ua kom yuam kev deformation yog qhov tseem ceeb. Viton-hom fluorine roj hmab yog siv ntau heev, thiab nws yog qhov kev txav ntawm kev txhim kho ntawm nws cov kev sib deev yuam kev. DuPont hauv Teb Chaws Asmeskas hauv xyoo 20th xyoo 60-70-xyoo kev cog lus los txhim kho qhov tsis kam ntawm cov roj hmab fluorine kom hloov tau deformation, tau ua tiav cov txiaj ntsig zoo.
