I-PTFE Seals PTFE LIP Seals PTFE Amafutha kawoyela

I-PolytetraFbuoroethylene Seal (PTFE) (eyaziwa nangokuthi i-PTFEAL Seal Ring noma i-PTFE OILAL Seal) iyisitatimende esiphezulu sokusebenzisa uphawu kwamakhemikhali, njengokuphikiswa okuhle kwamakhemikhali, kanye ne-coefficients ephansi ephakeme njll.

Izinzuzo zezimpawu zePTFE

1. Ukumelana nokugqwala okuhle kwamakhemikhali:

Ama-Ptfe Sands anokumelana kahle nokugqwayiza kwamakhemikhali amakhemikhali futhi angamelana nokuguguleka kwezinto ezihlukene zamakhemikhali afana nama-acids, alkali, nosawoti. Lesi sici senza ama-PTFE asetshenziswe kabanzi embonini yamakhemikhali, imboni yemithi kanye nomkhakha wokudla.

2. Ukumelana kakhulu okushisa okuphezulu:

Ama-PTFE Seals anokumelana okuphezulu okuphezulu kakhulu futhi angasebenza ezindaweni eziphakeme kakhulu zokushisa eziphakeme isikhathi eside. Iphoyinti lokuncibilika le-PTFE lingama-327 ° C, uhla lokushisa oluqhubekayo lokushisa lungu-200 ° C kuya ku-260 ° C, futhi izinga lokushisa lesikhathi esifushane lingafinyelela kuma-300 ° C, ngakho-ke kungasebenza ngokuqinile ezindaweni eziphakeme zokushisa. Lesi sici senza ukuthi ama-PTFE asetshenziswe kabanzi e-Aviation, Aerospe, Power Power kanye nezinye izinkambu.

3. I-coeffliction ephansi yokuncintisana:

Ama-polytetrafluorooroethylene Seals (ezaziwa nangokuthi njengezimpawu ze-PTFE noma izibuko zamafutha e-PTFE) zinezinkinga eziphansi kakhulu, zibenze basebenze kahle futhi isikhathi eside empilweni ebeka uphawu ezingxenyeni ezinyakazayo. Lesi sici senza ukuthi ama-PTFE asetshenziswe kabanzi emishini, izimoto, imikhumbi nakwezinye izinkambu.

4. Izindawo ezinhle zokufakwa kukagesi:

I-PTFEAL Seal iyinto enhle yokufakelwa kagesi yokufakelwa kagesi engasebenza ngokuqine ezindaweni eziphakeme ze-voltage. Lesi sici senza ukuthi ama-PTFE asetshenziswe kabanzi kuma-elekthronikhi, ngogesi nakwezinye izinkambu.

5. Ukuvikelwa okuhle kokuvikeleka:

Izimpawu ze-PTfe zinokumelana kahle nokungamelana kahle ngaphansi kwezimo ezinzima njengokuthwala umthwalo osindayo, isivinini esikhulu, kanye nokushisa okuphezulu. Lesi sici senza ukuthi ama-PTFE asetshenziswe kabanzi kwizimboni ezisindayo ezifana nemishini yobunjiniyela kanye nomkhakha we-petrochemical.

2. Okubi kwezimpawu ze-PTFE ze-PTFE--

1. Intengo ephakeme:

Uma kuqhathaniswa nezinye izinto zokubopha, intengo yezimpawu ze-PTFE iphakeme, futhi enye yezinto ezikhawula ukuthandwa kwayo.

2. Ukuqina okuphansi:

Ama-PTFE Seals anamandla aphansi futhi athambekele kumandla we-shear mehear, ngakho-ke angeke afaneleke kwezinye izinhlelo zokusebenza eziphezulu eziphakeme, eziphakeme kakhulu.

3. I-coefficient enkulu yokwandiswa:

Ama-polytetrafluorooroethylene Seals (abizwa nangokuthi njengezimpawu ze-PTFE noma izimpawu zamafutha e-PTFE) ane-coefficient enkulu yokwanda. Lapho izinga lokushisa lishintsha, zithambekele ekushintsheni okuyisici, ngaleyo ndlela zithinta umphumela wokufaka uphawu.

I-polytetraFetraFbuoroethylene (PTFE) seal seal ingena esikhundleni se-lip-shape amafutha kawoyela werabha, okuxazulula ngempumelelo inkinga yamanzi nokuvuza kawoyela kophawu lwamafutha enjoloba.

1. Izinzuzo ze-PTFE Amafutha Seal Seal

I-Polytetrafluoroethylene (PTFE), i-copolymer ye-tetrafluoroethyleneline. Inezinzuzo ezilandelayo:

.

(2) Ukuqina okushisayo: izinga lokushisa le-pyrolysis lingaphezulu kwama-400 ° C. Ngakho-ke, i-PTFE ingasebenza ngokujwayelekile ngaphakathi kobubanzi bokushisa buka -200 ° C kuya ku-300 ° C.

.

.

2. Ukuguqulwa kwe-PTFE OILOL SEAL ukuguqulwa

I-PTFE emsulwa ayigqokile. Ukuze kwenziwe kube lula, kufanele kugcwaliswe futhi kuguqulwe. Sisebenzisa izindlela ezimbili: eyodwa ukuguqulwa kokugcwalisa kwe-inorganic, engeza i-fiber yeglasi, i-carbon fiber, i-graphite, i-molybdenum disvulfide, njll. To PTFE. Okunye ukuguqulwa kwe-organic ukugcwaliswa, ukungeza i-polyphenene resin, i-polyphenene sulfide, njll. Ngokugcwalisa ukuguqulwa, ukumelana nokugqokwa kwe-polytetrafluoroethleetene kukhuphuka ngezikhathi ezingama-2000, futhi ukuqina nokuvuselelwa okushisayo kuyanda, kuvumela uphawu lwamafutha ukuba ahlangabezane nezidingo zempilo ephezulu.

3. Isimiso sokubopha uphawu se-PTFE

Izindebe zophawu lwamafutha e-PTFE zidonswa ekwakhekeni kwecilongo ngesikhathi sokulungiswa. Njengoba i-PTFE ine-Memory Shrinkage Ikhono ngemuva kokudonswa, ukushisa okungqubuzanayo okwenziwe ngesikhathi somsebenzi kuzokwenza ukuthi izindebe zinciphise ngokuqhubekayo, ngakho-ke usizo lwentwasahlobo aludingeki. , izokwanga umgodi ngokuqinile, uyivimbele ekubeni nanoma yiliphi igebe elinomkhawulo we-shaft, bese unxephezela ukugqokwa.

Ukuhlaziywa kwezinkambu zohlelo lokusebenza lwePolytetrafluoroethyleneInese Seals (eyaziwa nangokuthi njengezimpawu ze-PTFE noma izibuko zamafutha e-PTFE) -

1. Imboni yamakhemikhali PTFE uphawu lokubopha uphawu:

Ama-Ptfe Sands anokumelana kahle nokugqwayiza kwamakhemikhali amakhemikhali futhi angasebenza ngokuqine emithonjeni yezindaba enamandla kakhulu njengama-acids, alkali, nosawoti. Ngakho-ke, isetshenziswa kabanzi embonini yamakhemikhali yokuvalwa kwamapayipi ahlukahlukene, amaphampu, ama-valve nezinye izinto.

2. I-PTFE ibopha indandatho embonini yezemithi:

Izimpawu zePtfe ziya ngokuya zisetshenziswa embonini yezemithi ngoba zingamelana nokuguguleka kwamakhemikhali ahlukahlukene kanye nezinga lokushisa eliphakeme nezindawo eziphakeme kakhulu, ngenkathi zihlangana nezidakamizwa zezempilo futhi zingangcolisi izidakamizwa. Emishini yezemithi, imishini yezokwelapha, njll., Izimpawu zePTFE zisetshenziswe kabanzi.

3. Imboni yokudla ye-PTFE uphawu lokubopha uphawu:

Ama-Ptfe Seals nawo asetshenziswa kabanzi embonini yokudla ngenxa yokumelana kwawo kwamakhemikhali namakhemikhali ahlanzekile. Ekusebenzeni kokudla, ukugcinwa, izinto zokuhamba, njll., Izimpawu zePTFE zinganikeza ukuvikelwa kokubekwa uphawu okuthembekile.

4. Izindandatho zokubopha uphawu kwe-PTFE emkhakheni we-aerospace:

Ama-Ptfe Seals nawo asetshenziswa kabanzi emkhakheni we-aerospace ngenxa yokumelana kwawo okushisa okuphezulu okuphezulu kanye nezakhiwo zokugqwala kwamakhemikhali. Ezinjini ze-aerospace, i-spacecraft, izindiza, njll.

5. I-PTFE ibopha amasongo emkhakheni wemishini yemishini:

Izimpawu zePtfe zisetshenziswa kabanzi emkhakheni wezinto zokusebenza zemishini ngoba inenqwaba yokuphikisana nokuphikisana okuhle nokuphikiswa okuhle, okungathuthukisa ukusebenza kahle kanye nempilo yemishini yemishini. Kumathuluzi omshini, imishini ye-hydraulic, amaphampu, njll., Izimpawu zePTFE zingaqinisekisa ukusebenza okujwayelekile kwemishini.
