2. Yakanyanya kupisa kupisa kupisa:

Zvisimbiso zvePTFE zvine yakakwirira kupisa kupisa uye inogona kushanda munzvimbo dzakanyanyisa tembiricha yekushisa kwenguva yakareba kwenguva yakareba. Iyo yekunyungudutsa iyo PTFE ndeye 327 ° C, kuenderera mberi kushandisa tembiricha ndeye -00 Hunhu uhwu hunoita kuti PTFE SELS inoshandiswa zvakanyanya muAviation, Aerospace, simba renyukireya uye mimwe minda.

3. Low Friction Contrifficient:

PolytetraFluorootherylene Seals (zvakare anozivikanwa sePTFE zvisimbiso kana zvePTFE Oiri Zvisikwa Zvekunyanyisa Forfefficients Hunhu uhwu hunoita kuti PTFA zvisimbiso zvakanyanya kushandiswa mumachina, mota, ngarava uye mamwe minda.

4. yakanaka yemagetsi insulation zvivakwa:

Chisimbiso PTFE ndeye yakanaka kwazvo yemagetsi zvinhu zvekushandisa zvinogona kushanda zvine simba munzvimbo dzakakwirira dzekuvhota. Hunhu uhwu hunoita kuti PTFA zvisimbiso zvakanyanya kushandiswa mumagetsi, magetsi uye mamwe minda.

5. Pfeka zvakanaka kuramba:

Zvisimbiso zvePTFE zvine simba kupfeka kurwisa uye unogona kushandira kwenguva yakareba pasi pemamiriro ezvinhu akaomesesa senge mutoro wakakura, kumhanya kwakanyanya, uye kupisa kwakanyanya. Hunhu uhwu hunoita kuti PTFA inoshandiswa zvakazara muindasitiri inorema seinjiniya michina uye indasitiri yemapeturu.

2. Zvakaipa zvePTFE Zvisikwa--

1. Mutengo wepamusoro:

Kuenzaniswa nemimwe michina yekuisa chisimbiso, mutengo wezvisimbiso wePTFA zvakakwira, izvo zvakare chimwe chezvinhu zvinodzikisira mukurumbira wayo.

2. Yakanyanya kuderera:

Zvisimbiso zvePTFE zvine simba rakaderera uye dzinotarisirwa kune michina mashizha masimba masimba, saka vanogona kunge vasina kukodzera mune imwe yakakwirira-mutoro, yakakwirira-yekumanikidza mafiramu.

3. Kuwedzera Kwakakura Kunobatanidza:

PolytetraFluorootherylene Seals (zvakare anozivikanwa sePTFE Zvisimbiso kana Zvisimbiso Zvemafuta Oiri) zvine huwandu hwakakura hwekuwedzera. Kana tembiricha ichichinja, ivo vanowanzochinja kuchinja, nokudaro vachikanganisa chisimbiso.

Iyo yakazadzwa polytetrafluorohonelene (PTFE) chisimbiso chemafuta chinotsiva chisimbiso chemafuta emafuta, chinobudirira kugadzirisa dambudziko remvura uye mafuta maruva eiyo skeleton oiri chisimbiso chemafuta.

1. Zvakanakira zvePTFE Oiri Chisimbiso Zvinyorwa

PolytetraFluoroetherylene (PTFE), ndiye Coplymer weTetrafluorolerylene Monomer. Iyo ine zviero zvinotevera:

. "

(2) kugadzikana kwekunyora: Iyo pyrolysis tembiricha iri pamusoro pe400 ° C. Naizvozvo, ptfe inogona kushanda kazhinji mukati meiyo tembiricha ye -200 ° C kusvika 300 ° C.

.

2. PTFE Oiri Chisimbiso Kuzadza Kugadziridzwa

PTFE PTFE haina kupfeka. Kuti iite kuti ive inoshanda, inofanira kuzadzwa uye kushandurwa. Isu tinoshandisa nzira mbiri: Imwe ndeyekuzadza kusingaperi kuchema, kuwedzera girazi fiber, kabhoni fiber, graphite, molybdenamu kukuvara, etc. kune ptfe. Imwe yacho inozadza kuganhurira, kuwedzera polyphenylene resin, polyphenylene sulfide, etc. to polytetrafluorohylene (yakakodzera kucheneswa kwemvura, chikafu, uye chisimbiso chemishonga). Kubudikidza nekuzadza kugadziridzwa, kupfeka kupokana kwePolytetrafluorohler kwave kuwedzerwa munguva dzine zviuru zviviri, uye kuomarara uye kufambiswa kwerufu kwakawedzera, kubvumira chisimbiso chemafuta kuti zvisangane nehupenyu hwehupenyu hwakawanda.

3. PTFE Kuisa Mhedzisiro

Iwo muromo weiyo PTFE Oiri Chisimbiso inokweverwa muchimiro chehwamanda panguva yekugadzirisa. Sezvo PTFE ine ndangariro dzinodzvinyirira mushure mekukweverwa, kupisa kwekupokana kunowoneka pabasa kuchaita kuti muromo urege kuenderera mberi, saka rubatsiro rwechitubu harusi kudiwa. .

Kuongororwa kweminda yekushandisa yePolytetrafluorohylene Seals (zvakare inozivikanwa sePTFE Seals kana PTFE Oiri Zvisikwa Zvisungo) -

1. Makemikari indasitiri PTFE Sealing rin'i:

Zvisimbiso zvePTFE zvine Chemumoyo Kemical Corrosion kuramba uye kunogona kushanda zvine simba mune zvakanyanyisa kuora midhiya seakari, Alkalis, uye munyu. Naizvozvo, inoshandiswa zvakanyanya muindasitiri yemakemikari yekuisa mapipi akasiyana-siyana, mapapu, malves uye zvimwe zvishandiso.

2. PTFA inosimbisa chindori muindasitiri yemishonga:

Zvisungo zvePTFE chiri kuwedzera muindasitiri yemishonga nekuti vanogona kudzivisa kugura kubva kumakemikari akasiyana uye akadzika-tembiricha uye akasangana nemishonga yehutano. Mumidziyo yemishonga, zvekurapa zvekurapa, nezvimwewo, zvisimbiso zvePTFA zvakave kushandiswa zvakanyanya.

3. Chikafu Chekudya PTFE Selising rin'i:

Zvisimbiso zvePTFE zvakare zvinoshandiswa zvakanyanya muindasitiri yechikafu nekuda kwekunaka kwavo kwemakemikari kurwisa uye hutsinye zvivakwa. Mukudya kwekudya, kuchengetedza, kutakura, nezvimwewo, zvisimbiso zvePTFA zvinogona kupa kuvimbika kuvimbika kusungwa.

4. PTFA inosimbisa mhete munhamba yeAerospace:

Zvisimbiso zvePTFE zvakare zvinoshandiswa zvakanyanya munhamba yeAerospace nekuda kwekunaka kwavo kupisa kwekushambadzira uye nemakemikari corrosion zvivakwa. Mubatanidzwa yeAerospace, spacecraft, ndege, nezvimwe, nezvisimbiso, zvePTFA zvinogona kupa chisimbiso chakavimbika uye chidziviriro kuti ive nechokwadi chekushandisa zvigadzirwa.

5. PTFA inosimbisa mhete dziri mumunda wezvemakaneti michina:

Zvisimbiso zvePTFE zvakare zvinoshandiswa zvakanyanya mumunda wezvemakaniki emidziyo nekuti zvine runyararo rwakadzika uye rwakanaka kupfeka, izvo zvinogona kuvandudza kushanda uye hupenyu hwekushandisa michina. Mumabhaishi emachina, hydradulic michina, mapapipi, etc., Zvisimbiso zvePTFA zvinogona kuve nechokwadi chekushanda kwakajairika kwemidziyo.
