Cov khoom siv graphiteyog hom tshiab ntawm cov khoom sealing, thiab nws tseem yog ib hom khoom tseem ceeb ntawm cov khoom ntim hauv kev lag luam kev lag luam. Nws muaj cov tshuaj tiv thaiv corrosion zoo, muaj siab thiab kub tsis kam, kev sib txhuam ntawm hluav taws xob, elasticity corriation, elasticity, thiab qis permeability rau kua thiab gases.
Graphite gasketstuaj yeem ua av lossis kaw los ntawm cov phiaj ntshiab graphite lossis hlau (cov phiaj hlau, cov phiaj xwm tiaj tus, cov phiaj xwm ntxiv rau cov phiaj xwm ua haujlwm ib yam nkaus.
1. Cov yam ntxwv ntawm cov graphite gasket:
1. Siab - Purity graphite muaj qhov tsis tsim nyog immnessability rau roj thiab kua, xws li ib daim phaj nyias nyias nrog lub helium ntawm 0.125mm, tus nqi ntawm cov helium tsuas yog 2 * 10cm3 / s.
2. Cov cua kub tsis kam. Qhov ntsuas kub uas yoog raws graphite hauv tsis - hydrolytic nruab nrab yog - 200 ~ 600℃, tab sis nws yooj yim yuav oxidized hauv hydrolytic nruab nrab.
3. Anisotropy: Cov thermal conduction, hluav taws xob conductive, hluav taws xob conduction thiab nthuav coefficievic ntawm coninple graphite tau pom tseeb anisotropy.
4. Lub zog UV tsis kam.
5. Cov tshuaj corrosion tsis zoo, tshuaj lom neeg ruaj khov rau cov tshuaj lom neeg cov tshuaj lom neeg, esters, dej ntws tawm, thiab lwm yam.
Txawm li cas los xij, muaj qee qhov kev txwv nyob hauv nruab nrab nruab nrab.
6. Tsawg ntom ntom, lub zog siab, kev muag khoom zoo thiab lub zog.
Cov kev ntsuas ntawm kev siv cov graphite yoog
Siv hauv kev siv yeeb nkab flanges, kev hloov cua sov, lub zog npog, cua daj cua dub, cua sov, tso cov kav dej, ua haujlwm, thiab lwm yam, thiab lwm yam, thiab lwm yam, thiab lwm yam, thiab lwm yam, thiab lwm yam, thiab lwm yam, thiab lwm yam, thiab lwm yam, thiab lwm yam, thiab lwm yam
Siv tau nruab nrab: dej, chav dej, roj, kua qaub, alkali, organic kuab, ammonia, hydrogen, thiab lwm yam.
2. Stainless hlau ntxiv ntxiv dag zog rau cov graphite gasket
Graphite Siab - Zos Gaskets, tseem hu ua graphite inorganic gaskets, yog ua los ntawm cov ntawv qhia ntxiv graphite daim ntawv lossis hauv av. Cov khoom siv hauv ob sab tuaj yeem yog tib daim ntawv hlau raws li yuav tsum tau ua. Vim yog cov neeg kho tshuab muaj zog ntawm cov gasetic yooj yim, thiab ntxiv rau cov roj ntsha me me, thiab ntxiv ntxiv ntxiv ntxiv txhim kho cov tshuab hluav taws xob muaj zog. Cov khoom lag luam zoo heev xws li tshuaj lom neeg tawm tsam, hluav taws xob hluav taws xob tsis yeem, cov cua kub siab, thiab lub neej ntev.
Ntxiv kom zoo ntxiv rau graphite gasket faib tawm:
1. Carbon Steel ntxiv dag zog rau covGraphite gasket gasket: Qhov kawg ntawm daim ntawv yooj yim clamped yog clamped nrog carbon stip sawb (0.2 hli), thiab tom qab ntawd av, uas ntxiv dag zog rau kev kho tshuab zog.
2. 304 stainless hlau ntxiv dag zog graphite gaskite faab flakes yog txuas rau ob sab ntawm 304 stainless hlau, uas muaj qhov tsis tshua muaj zog. Nws tseem haum rau ntau qhov loj thiab tsawg thiab cov duab sib txawv, thiab tseem muaj yooj yim thauj. Nws tseem yog ib daim teb nrov heev. Ntau cov gaskets.
3. 316 Stainless hlau ntxiv dag zog rau cov graphite gasket: nws muaj zoo corrosion tsis kam thiab muaj lub zog kub siab, tab sis tus nqi kuj qis dua li lwm cov ntaub ntawv.
3. Hlau graphite woven rau gasket
Hlau - Graphite Woven Gaskets yog ib hom hlau - Inorganic gaskets woven los ntawm hlau ib daim hlau thiab graphite strips. Lawv yog interwoven ntawm v - puab lossis w - puab nyias nyias hlau thiab fillers. Nrog ntau - channel sib khi thiab tus kheej - Zawm kom nruj kev ua haujlwm, nws tsis muaj zog rau qhov flaws ntawm cov flange nias rau hauv cov chaw sib khi, thiab nws tsis yog Nacl Flange Sealing nto; Nws yog ib qho yooj yim rau dismantle, thiab tuaj yeem tshem tawm cov cawv ntawm kev kub siab, ntsuas kub hloov thiab tshuab kev co; Nws tuaj yeem siv tau ntawm qhov kub thiab txias thiab kub kub nws tswj tau zoo sib khi ua nyob rau hauv ntau yam kev sib tw ua ke xws li, lub tshuab nqus tsev siab, poob siab thiab kev co. Cov hlau nyem Woven Gasket haum rau qhov kub thiab txias, thiab saj zawg zognpaimSiv tawv yog haum rau qhov kub - 196 ~ 650°C (tsis qis dua 450°C nyob rau hauv cov hydrolysis nruab nrab)
