I-China High High Temp Gasket Izinto ezibonakalayo

Eminyakeni yamuva, kube nokwanda okukhulu kwesidingo seAma-gaskets aphezulu aphezulu. Kodwa-ke, indlela etholakala kaningi yokukhethwa kwezinto ezibonakalayo isuselwa kwizethulo ezingesihle futhi ayicabangi ama-nuances wesicelo sangempela. Namuhla sizozama ukuthola ukuthi yiziphi izinto ezihambelana kakhulu emakethe yamaShayina, yiziphi izinkinga eziphakamayo lapho zibasebenzisa futhi yiziphi izixazululo - ezikhona zikhona. Futhi, ngokungananazi, azihlali zihambisane nalokho okumenyezelwe kuzinhlu.

Ukubuyekezwa: Ukukhetha impahla efanele - ukhiye wokuthembeka

Ukukhethaimpahla evuthayo ephakeme- Lokhu akuyona nje ukukhetha kwezinga lokushisa. Lona umsebenzi wobunjiniyela bonke obudinga ukuqonda kwezimpawu zemishini, yamakhemikhali neye-armal yezinto ezibonakalayo, kanye nezimo zokusebenza. Ukukhetha okungalungile kungaholela ekunciphiseni ngaphambi kwesikhathi, ekuguqukeni kwe-gasket futhi, ngenxa yalokho, ekuqhekekeni okukhulu kwemishini. Sizocubungula izinketho ezivame kakhulu, izinzuzo zazo kanye nokubi, kanye nokunikeza izibonelo zokuzijwayeza.

Izinhlobo eziphambili zezinto zokwakha ezisetshenziselwa ama-gaskets aphezulu eChina

Izinto ezithandwa kakhulu yizinhlanganisela ze-ceramic, ama-metallogids, ama-polymers wokushisa nama-fluororoplasts. Ngamunye wabo unezimpawu zawo ezenza zilungele imisebenzi ethile. Isibonelo, ukuze usebenze emazingeni okushisa aphezulu kakhulu (ngenhla kwe-1200 ° C), i-silicon carbide noma i-silicon nitride imvamisa isetshenziswa kakhulu. Kodwa-ke, lezi zinto zokwenziwa zivame ukunteka ngokwengeziwe futhi zidinga ukulungiswa okungaphezulu komhlaba.

Ama-Curamic Composites: Amandla Nokumelana

Ama-Curamic Composites, ikakhulukazi ngesisekelo se-silicon Carbide (Sic) kanye ne-Silicon Nitride (I-SI2N4), abonakala ngokumelana nokushisa okuphezulu, amandla omshini kanye nokumelana namathonya amakhemikhali. Zilungele ukusetshenziswa emampandeni, ama-boilers nezinye izindawo ezinolaka. Kodwa-ke, izindleko zabo eziphakeme nobunzima ekusebenzeni umkhawulo ukusetshenziswa kwazo.

Sibhekane nenkinga yokuqhekeka kwama-gaskets asopha ama-sic ngenhla yembulo yokushisa ebukhali. Kwavela ukuthi lokhu kungenxa yokuphikiswa okunganele kokushisa okuphelele kokuthengisa okusetshenziselwa ukuwalungisa. Kulokhu, ukushintshwa komthengisi nge-glue ekhethekile ye-ceramic kwandise kakhulu impilo yokubekwa.

Ukuhlangana kwe-Met of Ligs: Ukuphikiswa okukhulu kokuyekethisa

I-Metallogdys, njenge-Niobid Hydridi (NBH2) kanye neTitanium Hydrides (TIH2), kukhona ukuyekethisa okuhle phakathi kwenani nezimpawu. Banokumelana nokushisa okuphezulu (kufika ku-800-900 ° C), ukumelana kahle nokugqwala kanye nezindleko eziphansi. Kuvame ukusetshenziswa kumandla embonini yamakhemikhali.

Kepha kukhona ama-nuances lapha. Lapho usebenza nge-metallogidrides, kuyadingeka ukuthi unake ukuthambekela kwabo ku-oxidize lapho kukhona umoya-mpilo. Ngakho-ke, izimbobo ezikhethekile zokuvikela noma umoya we-inert zivame ukudingeka.

I-Heat -Resistant Polymers: Ukuvumelana nezimo kanye nokusebenza kahle

Ama-polymers okushisa-anjenge-PTFE (Teflon), Peek kanye ne-PPS, anikele ngezimo nezimo kanye nokushibhile okuhlobene. Zisetshenziswa kabanzi ezindaweni ezahlukahlukene lapho kutholakala khona ukubekwa uphawu kanye nokuhlangana. Kodwa-ke, ukumelana kwabo kokushisa kukhawulelwe (kuvame ukuba ku-200-250 ° C), futhi bangakhubazeka ngaphansi kwethonya lamazinga okushisa aphezulu nengcindezi.

Kwelinye lamaphrojekthi, sisebenzise ama-gaskets e-PTFE ukuhlanganisa i-reactoror asebenza ngo-180 ° C. Ama-gaskets alahlekelwe ngokushesha izakhiwo zazo zokubopha, ezaholela ekuvuleni kwazo. Ngenxa yalokhu, sashintshela kuma-metric -in -law gaskets, okunikeze ukubekwa uphawu okuthe xaxa.

Izinkinga ezibhekene nalapho zisebenzisaama-gaskets aphezulu aphezulu

Naphezu kwezinhlobonhlobo zezinto zokwakha, lapho usebenzisaama-gaskets aphezulu aphezuluIzinkinga ezithile zivame ukuvela. Enye yezinto ezivame kakhulu ukuhlukaniswa kokubekwa ngaphansi kwethonya lamazinga okushisa aphezulu nengcindezi. Lokhu kungaholela ekuvuzeni nasekunciphiseni ukusebenza kahle kwemishini.

Enye inkinga ukukhulisa ama-gaskets kumidiya enolaka. Ukugqwala kunganciphisa kakhulu impilo yenkonzo yokubeka futhi kuholele ekuqhekekeni okukhulu kwemishini. Ukuxazulula le nkinga, kuyadingeka ukuthi ukhethe izinto zokwakha ezimelana nezimo ezithile ezinolaka futhi usebenzise izigqoko zokuvikela.

Izinto eziphansi-)

Ngeshwa, izinto ezingezinhle zangasese zitholakala emakethe yaseChina. Lokhu kungaholela ezinkingeni ezinkulu ngokubekwa uphawu kanye nokwethenjwa kwemishini. Kubalulekile ukuthenga izinto ezivela kubahlinzeki abathembekile ngezitifiketi zekhwalithi.

Sihlangane kaninginingi ama-gaskets amenyezelwe njenge-SIC, kepha empeleni equkethe isabelo esibalulekile sezinto ezishibhile. Ama-gaskets anjalo ahluleka ngokushesha, okuholele ekulahlekelweni kwezezimali okubalulekile.

Isipiliyoni Esiwusizo: Izincomo namathiphu

Ngokusekelwe kokuhlangenwe nakho kwethu, singanikeza izincomo eziningana zokukhetha nokusebenzisaama-gaskets aphezulu aphezulu. Okokuqala, kuyadingeka ukuhlaziya ngokucophelela izimo zokusebenza, kufaka phakathi izinga lokushisa, ingcindezi, ukuhlukunyezwa kwamandla kanye nobukhona bokudlidliza. Okwesibili, kuyadingeka ukukhetha izinto zokwakha ezihambelana nalezi zimo. Okwesithathu, kuyadingeka ukusebenzisa izinto ezisezingeni eliphakeme ezivela kubahlinzeki abathembekile. Futhi ekugcineni, kuyadingeka ukufaka kahle ama-gaskets, ubheka zonke izidingo zobuchwepheshe.

Ukuqapha njalo kwama-gaskets kanye nokubuyiselwa okufika ngesikhathi kwama-gaskets alimele kuyizinto ezibalulekile futhi eziqinisekisa ukuthembeka kwemishini. Lokhu, yiqiniso, kudinga izindleko ezingezekile, kepha zingaphansi kakhulu kwezindleko zokulungiswa nesikhathi sokuphumula.

Izibonelo zamaphrojekthi aphumelelayo

Sisebenzise ngempumelelo amaphrojekthi amaningi ahlobene nokusetshenziswaama-gaskets aphezulu aphezulu. Isibonelo, kwinkampani ekhiqiza imikhiqizo ye-ceramic, sithuthukise futhi safaka ama-gaskets ezitofuni zokudubula, okunikeze ukuqina okuphezulu kanye nokwethenjwa kwemishini. Ukuze inkampani isebenza embonini ye-petrochemical, sithuthukise futhi safaka ama-gaskets kuma-reactors aqinisekise ukumelana nezimo ezinolaka.

Onke la maphrojekthi asetshenziswe ngempumelelo ngenxa yokuhlaziywa ngokuphelele kwezimo zokusebenza, ukukhetha kwezinto ezifanelekile kanye nokufakwa okulungile kwama-gaskets. Sihlala sizama ukunikela amakhasimende ethu ikhambi elifanele, elinikezwe izidingo zalo kanye nesabelomali.
