Izinto zegraphiteluhlobo olutsha lwezinto zokutywina, kwaye luhlobo olubalulekileyo lwezinto zokutywina kwishishini lemizi-mveliso.Inokumelana nokugqwesa okugqwesileyo, ukumelana nobushushu obuphezulu kunye nokusezantsi, ukumelana nemitha ye-electromagnetic, into encinci yokukhuhlana, ukuzithambisa, ukuqina, kunye nokungena okuncinci kulwelo kunye neegesi.
Iigaskets zegraphiteinokugutyungelwa okanye igximfizwe kwiipleyiti zegraphite ecocekileyo okanye isinyithi (iipleyiti zamazinyo, iipleyiti ezisicaba, iminatha) ukuqinisa ngakumbi iipleyiti zegraphite ngokweemeko ezifanayo zokusebenza.
1. Iimpawu zegasket yegraphite eguquguqukayo:
1. I-graphite yococeko oluphezulu lunokungahambi kakuhle kwigesi kunye nolwelo, njengeplate encinci kunye nobukhulu be-0.125mm, izinga le-helium li-2 * 10-1cm3 / s kuphela.
2. Ukumelana nobushushu obuhle.Ubushushu begraphite eguquguqukayo kwi-non-hydrolytic medium yi-200 ~ 600℃, kodwa kulula ukuba i-oxidized kwi-hydrolytic medium.
3. I-Anisotropy: I-thermal conduction, conductivity yombane kunye nokwandiswa komlinganiso we-graphite eguquguqukayo ine-anisotropy ebonakalayo.
4. Ukuchasana okunamandla kwe-UV.
5. Ukumelana ne-corrosion efanelekileyo, ukuzinza kakuhle kweekhemikhali kwii-solvents zamakhemikhali eziqhelekileyo, i-esters, umphunga wamanzi, ukunciphisa imidiya, njl.
Nangona kunjalo, kukho imida ethile kwi-hydrolysis medium.
6. Ubuninzi obuphantsi, amandla aphezulu, ukuthamba okuhle kunye nokuqina.
Umda wokusetyenziswa kwegraphite eguquguqukayo
Isetyenziswe kwiiflange zemibhobho yezoshishino, i-heat exchangers, i-valve cover, i-condensers, i-air amplifiers, i-exhaust pipes, iifriji, njl.
Isixhobo esisebenzayo: amanzi, umphunga, ioyile, iasidi, ialkali, isinyibilikisi seorganic, ammonia, ihydrogen, njl.
2. Intsimbi engatyiwayo yomeleza ngakumbi i-graphite gasket
Iigaskets eziphezulu zegraphite, ezikwabizwa ngokuba yi-graphite inorganic gaskets, zenziwe ukusuka kwimicu yephepha legraphite eyomeleziweyo ngakumbi okanye umhlaba.Impahla ye-lining ingaba yintsimbi efanayo njengoko ifunwa.Ngenxa yamandla aphezulu omatshini we-flexible gaskets ye-graphite, ifanelekile kwi-gaskets ene-diameter encinci, kunye nokuqiniswa ngakumbi kwe-graphite gaskets kuphucula kakhulu amandla omatshini.Iipropathi ezigqwesileyo ezinje ngokumelana nokubola kweekhemikhali, ukumelana nemitha ye-electromagnetic, ukumelana nobushushu obuphezulu / obuphantsi, kunye nobomi obude.
Uphuculo olongezelelweyo kuhlelo lwe-graphite gasket:
1. Intsimbi yeCarbon yomeleza ngakumbiigraphite gasket: isiphelo sephepha legraphite eliguquguqukayo ligxininiswe nge-carbon steel strip (0.2mm), kwaye emva koko umhlaba, oqinisa amandla omatshini.
2. I-304 insimbi engenastainless yomeleza ngakumbi i-graphite gasket: iiflake zegraphite eziguquguqukayo zincanyathiselwe kumacala omabini e-304 yentsimbi engenastainless, enamandla amakhulu kakhulu omatshini.Ikwafanelekile kwiisayizi ezinkulu ezahlukeneyo kunye neemilo ezintsonkothileyo, kwaye kulula ukuyihambisa.Ikwayinkalo yesicelo ethandwa kakhulu.Uluhlu olubanzi lweegaskets.
3. I-316 insimbi engenasici iqinisa ngakumbi i-graphite gasket: inokumelana ne-corrosion efanelekileyo kunye namandla aphezulu okushisa, kodwa ixabiso liphantsi kunezinye izinto.
3. Isinyithi segraphite elukwe kwigasket
Iigaskithi ezilukiweyo zesinyithi luhlobo lweegaskiti zentsimbi ezingaphiliyo ezilukwe ngemicu yentsimbi kunye nemicu yegraphite.Zithungelwe kwimilo yentsimbi emile okwe-V okanye engu-W kunye nezihluzi.Ngokutywinwa kwamatshaneli amaninzi kunye nemisebenzi yokuziqinisa, ayikhuselekanga kwiziphene zeflange ecinezelwe kwindawo yokutywina, kwaye ayisiyiyo i-NaCl flange yokutywina indawo;kulula ukuyichitha, kwaye inokuphelisa ngokuyinxenye impembelelo yoxinzelelo, utshintsho lobushushu kunye nokungcangcazela koomatshini;inokusetyenziswa kwiqondo lobushushu eliphezulu kunye nobushushu obuphantsi Igcina ukusebenza ngokugqwesileyo kokutywinwa phantsi kweemeko ezinzima ezahlukeneyo kwiindawo zokujikeleza ezifana ne-vacuum ephezulu, ukothuka kunye nokungcangcazela.I-metal graphite ephothiweyo i-gasket ifanelekile kwiqondo lokushisa, kunye ne-flexibleigraphiteibhanti ifanelekile kwiqondo lokushisa -196 ~ 650°C (hayi ngaphantsi kwe-450°C kwi-hydrolysis medium)
