Graphite khoomyog ib yam tshiab ntawm cov khoom siv sealing, thiab nws kuj yog ib qho tseem ceeb ntawm cov khoom siv sealing hauv kev lag luam.Nws muaj kev tiv thaiv zoo corrosion, siab thiab kub tsis kam, hluav taws xob hluav taws xob tiv thaiv, kev sib txhuam me me, nws tus kheej lubrication, elasticity, thiab tsis tshua muaj permeability rau cov kua thiab gases.
Graphite gasketstuaj yeem ua hauv av los yog stamped los ntawm cov graphite daim hlau ntshiab lossis hlau (cov hniav hniav, daim hlau tiaj tus, cov nets) kom ntxiv dag zog rau graphite phaj raws li tib yam kev ua haujlwm.
1. Cov yam ntxwv ntawm saj zawg zog graphite gasket:
1. High-purity graphite muaj zoo impermeability rau roj thiab kua, xws li ib tug nyias phaj nrog ib tug tuab ntawm 0.125mm, tus nqi ntawm helium tsuas yog 2 * 10-1cm3 / s.
2. Zoo kub tsis kam.Qhov kub ntawm qhov hloov pauv graphite hauv qhov nruab nrab tsis-hydrolytic yog -200 ~ 600℃, tab sis nws yooj yim rau oxidized hauv hydrolytic nruab nrab.
3. Anisotropy: Lub thermal conduction, hluav taws xob conductivity thiab expansion coefficient ntawm saj zawg zog graphite muaj cuab kev anisotropy.
4. Muaj zog UV tsis kam.
5. Zoo corrosion kuj, zoo tshuaj stability rau cov tshuaj solvents, esters, dej vapor, txo cov xov xwm, thiab lwm yam.
Txawm li cas los xij, muaj qee qhov kev txwv hauv qhov nruab nrab hydrolysis.
6. Tsawg ceev, siab zog, zoo softness thiab resilience.
Scope ntawm daim ntawv thov ntawm saj zawg zog graphite
Siv nyob rau hauv industrial yeeb nkab flanges, tshav kub exchangers, valve npog, condensers, cua amplifiers, tso kav dej, tub yees, thiab lwm yam.
Siv nruab nrab: dej, chav, roj, acid, alkali, organic hnyav, ammonia, hydrogen, thiab lwm yam.
2. Stainless hlau ntxiv dag zog rau graphite gasket
Graphite high-strength gaskets, tseem hu ua graphite inorganic gaskets, yog tsim los ntawm ntxiv dag zog graphite daim ntawv strips los yog hauv av.Cov khoom siv hauv ob sab phlu tuaj yeem yog tib daim ntawv hlau raws li xav tau.Vim lub siab mechanical zog ntawm saj zawg zog graphite gaskets, nws yog haum rau gaskets nrog me me diameters, thiab ntxiv dag zog rau graphite gaskets zoo heev txhim kho cov neeg kho tshuab zog.Cov khoom zoo xws li tshuaj tiv thaiv corrosion, hluav taws xob hluav taws xob tiv thaiv, siab / qis kub tsis kam, thiab lub neej ntev.
Ntxiv kev txhim kho rau graphite gasket kev faib tawm:
1. Carbon steel ntxiv dag zog rau lubgraphite gasket: qhov kawg ntawm daim ntawv hloov pauv graphite yog clamped nrog cov pa roj carbon steel sawb (0.2 hli), thiab tom qab ntawd hauv av, uas ua kom muaj zog ntawm cov neeg kho tshuab.
2. 304 stainless hlau ntxiv dag zog rau graphite gasket: saj zawg zog graphite flakes yog txuas rau ob sab ntawm 304 stainless hlau, uas muaj cov neeg kho tshuab siab heev.Nws kuj tseem haum rau ntau qhov loj me thiab cov duab nyuaj, thiab kuj yooj yim rau kev thauj mus los.Nws kuj yog ib daim ntawv thov nrov heev.Muaj ntau hom gaskets.
3. 316 stainless hlau ntxiv dag zog rau cov graphite gasket: nws muaj kev tiv thaiv corrosion zoo thiab kub siab zog, tab sis tus nqi kuj tseem qis dua lwm cov ntaub ntawv.
3. Hlau graphite woven rau hauv gasket
Hlau-graphite woven gaskets yog ib hom hlau-inorganic gaskets woven los ntawm hlau strips thiab graphite strips.Lawv yog interwoven los ntawm V-puab los yog W-shaped nyias steel strips thiab muab tub lim.Nrog ntau txoj kev sib khi thiab kev ua haujlwm ntawm tus kheej, nws tsis yooj yim rau qhov tsis zoo ntawm flange nias rau hauv qhov chaw sib khi, thiab nws tsis yog NaCl flange sealing nto;nws yog ib qho yooj yim rau dismantle, thiab muaj peev xwm tshem tawm ib feem ntawm lub zog ntawm lub siab, kub hloov thiab txhua yam kev co;Nws tuaj yeem siv rau ntawm qhov kub thiab txias tsis tshua muaj Nws tswj kev ua tau zoo sealing nyob rau hauv ntau yam hnyav ntawm cov pob qij txha xws li, lub tshuab nqus tsev siab, kev poob siab thiab kev co.Cov hlau graphite woven gasket yog haum rau qhov kub thiab txias, thiab hloov taugraphiteTxoj siv yog tsim rau qhov kub thiab txias -196 ~ 650°C (tsis qis dua 450°C hauv qhov nruab nrab hydrolysis)
