I-graphite impahlawuhlobo olusha lwempahla yokuvala, futhi luwuhlobo olubalulekile lwezinto zokuvala embonini yezimboni.Inokumelana nokugqwala okuhle kakhulu, ukumelana nokushisa okuphezulu nokuphansi, ukumelana nemisebe ye-electromagnetic, into encane yokungqubuzana, ukuzigcoba ngokwakho, ukunwebeka, kanye nokungena okuncane oketshezini namagesi.
I-graphite gasketsingagaywa noma igxivizwe kusuka kumapuleti e-graphite ahlanzekile noma insimbi (amapuleti amazinyo, amapuleti ayisicaba, amanetha) ukuze kuqhutshekwe nokuqinisa amapuleti e-graphite ngokuvumelana nezimo ezifanayo zokusebenza.
1. Izici ze-flexible graphite gasket:
1. I-graphite ehlanzekile kakhulu inokungangeni kahle kwegesi noketshezi, njengepuleti elincane elinobukhulu obungu-0.125mm, izinga le-helium liyi-2 * 10-1cm3 / s kuphela.
2. Ukumelana nokushisa okuhle.Izinga lokushisa le-graphite eliguquguqukayo ku-non-hydrolytic medium lingu-200 ~ 600℃, kodwa kulula ukufakwa i-oxidized ku-hydrolytic medium.
3. I-Anisotropy: I-thermal conduction, conductivity kagesi kanye ne-coefficient yokwandisa ye-flexible graphite ine-anisotropy esobala.
4. Ukumelana ne-UV okuqinile.
5. Ukumelana nokugqwala okuhle, ukuzinza okuhle kwamakhemikhali kuma-solvents amakhemikhali ajwayelekile, ama-esters, umhwamuko wamanzi, ukunciphisa imidiya, njll.
Kodwa-ke, kunemikhawulo ethile ku-hydrolysis medium.
6. Ukuminyana okuphansi, amandla aphezulu, ukuthamba okuhle nokuqina.
Ububanzi bokusetshenziswa kwe-graphite eguquguqukayo
Isetshenziswa kuma-flange amapayipi ezimboni, okushintshanisa ukushisa, izembozo ze-valve, ama-condensers, ama-air amplifiers, amapayipi okukhipha umoya, amafriji, njll.
Isisetshenziswa esisebenzayo: amanzi, umusi, uwoyela, i-asidi, i-alkali, i-organic solvent, i-ammonia, i-hydrogen, njll.
2. Insimbi engagqwali iqinisa ngokwengeziwe i-graphite gasket
Ama-gaskets aphezulu we-graphite, aziwa nangokuthi ama-graphite inorganic gaskets, enziwa ngokuqhubeka nokuqiniswa kwephepha lephepha le-graphite noma inhlabathi.Impahla ye-lining ingaba ishidi lensimbi elifanayo njengoba kudingeka.Ngenxa yamandla aphezulu emishini yama-graphite gaskets aguquguqukayo, afaneleka ama-gaskets anama-diameter amancane, futhi ukuqiniswa okuqhubekayo kwama-graphite gaskets kuthuthukisa kakhulu amandla omshini.Izakhiwo ezinhle kakhulu njengokumelana nokubola kwamakhemikhali, ukumelana nemisebe ye-electromagnetic, ukumelana nezinga lokushisa eliphezulu/eliphansi, nempilo ende.
Ezinye izithuthukisi zokuhlukaniswa kwe-graphite gasket:
1. Insimbi ye-Carbon iqinisa ngokwengeziwei-graphite gasket: ukuphela kweshidi le-graphite eliguquguqukayo liboshwe nge-carbon steel strip (0.2mm), bese kuba phansi, okuqinisa amandla omshini.
2. Insimbi engagqwali engu-304 iqhubeka iqinisa i-graphite gasket: ama-flexible graphite flakes anamathiselwe nhlangothi zombili ze-304 stainless steel, enamandla amakhulu ngokwemishini.Ibuye ifanele amasayizi amakhulu ahlukahlukene kanye nezimo eziyinkimbinkimbi, futhi kulula ukuyihambisa.Futhi kuyinkambu yesicelo ethandwa kakhulu.Uhlu olubanzi lwama-gaskets.
3. I-316 insimbi engagqwali iqinisa ngokwengeziwe i-graphite gasket: inokumelana nokugqwala okuhle namandla okushisa aphezulu, kodwa izindleko nazo ziphansi kunezinye izinto.
3. I-graphite yensimbi elukwe ibe yi-gasket
Ama-gasket alukiweyo e-metal-graphite awuhlobo lwama-gaskets ensimbi-inorganic alukwa ngemicu yensimbi nemicu yegraphite.Zilukwe ngensimbi emincane emise okwe-V noma engu-W kanye nezigcwalisi.Ngokuvala iziteshi eziningi kanye nemisebenzi yokuziqinisa, ayisengozini yokushiyeka kwe-flange ecindezelwe endaweni yokuvala, futhi akuyona indawo yokuvalwa kwe-NaCl flange;kulula ukuyihlakaza, futhi ingaqeda kancane ithonya lokucindezela, ukuguquka kwezinga lokushisa kanye nokudlidliza kwemishini;ingasetshenziswa emazingeni okushisa aphezulu kanye nezinga lokushisa eliphansi Igcina ukusebenza okuhle kakhulu kokuvala ngaphansi kwezimo ezinzima ezihlukahlukene emalungeni omjikelezo njengokuthi, i-vacuum ephezulu, ukushaqeka nokudlidliza.I-metal graphite elukiweyo gasket ifanele izinga lokushisa, kanye nezimoi-graphiteibhande lifanele izinga lokushisa -196~650°C (hhayi ngaphansi kuka-450°C ku-hydrolysis medium)
