PTFE Composites Yepamusoro: Kuenzanisa Kwehunyanzvi hweGirazi Fiber, Carbon Fiber, uye Graphite Fillers

Polytetrafluoroethylene (PTFE), inozivikanwa se "mambo wepurasitiki," inopa makemikari anodzivirira, ine mwero wekukweshana wakaderera, uye inogadzikana mumamiriro ekunze ekudziya kwakanyanya. Zvisinei, zvipingamupinyi zvayo—zvakadai sekusapfeka zvakanaka, kuomarara kushoma, uye kukwira kweropa—zvakakonzera kukura kwemafuta akazara.PTFE compositesNekushandisa zvinhu zvinozadza senge girazi fiber, kabhoni fiber, uye graphite, vagadziri vanogona kugadzirisa hunhu hwePTFE kuti huenderane nezvinodiwa mundege, mota, uye kuvharwa kwesimbi mumaindasitiri. Chinyorwa chino chinoongorora kuti zvinhu izvi zvinovandudza sei PTFE uye chinopa gwara rekusarudza chinhu chakakodzera zvichienderana nezvinodiwa pakushanda.

1. Kudiwa Kwekugadziriswa kwePTFE​

PTFE yakachena inobudirira mukudzivirira ngura uye kukweshana kushoma asi ine hutera hwemakanika. Semuenzaniso, kudzivirira kwayo kupfeka hakuna kukwana kushandiswa kwe dynamic sealing, uye inoshanduka kana ichimanikidzwa kwenguva refu (kuyerera kunotonhora). Fillers dzinogadzirisa matambudziko aya nekushanda sema skeletons anosimbisa mukati mePTFE matrix, zvichivandudza kudzivirira kukwesha, kushivirira kupfeka, uye thermal conductivity pasina kukanganisa zvakanakira zvayo zvikuru.

2. Girazi Fiber: Chinosimbisa Mari Inoshanda​

Zvimiro Zvikuru​

Kusapfeka: Girazi regirazi (GF) rinoderedza kusapfeka kwePTFE nekusvika ka500, zvichiita kuti ive yakakodzera nzvimbo dzine mutoro wakawanda.

Kuderedza Kukweva: GF inowedzera kugadzikana kwezvikamu, ichideredza kushanduka kwechinhu pasi pekumanikidzwa kunoramba kuripo.

Miganhu yekupisa nemakemikari: GF inoshanda zvakanaka mukupisa kusvika ku400°C asi inoora mu hydrofluoric acid kana mabhesi akasimba.

Mashandisirwo​

PTFE yakasimbiswa neGF inoshandiswa zvakanyanya muzvisimbiso zve hydraulic, ma cylinders e pneumatic, uye ma gasket eindasitiri uko simba remakanika uye kushandiswa kwemari zvinokosheswa. Kuenderana kwayo nezvimwe zvinowedzera zvakaita seMoS₂ kunowedzera kugadzirisa kudzora kukweshana.

3. Carbon Fiber: Sarudzo Yekushanda Kwazvo​

Zvimiro Zvikuru​

Simba uye Kuoma: Carbon fiber (CF) inopa simba rekusimba uye flexural modulus, inoda huwandu hwakaderera hwekuzadza pane GF kuti iwane simba rakafanana.

Kufambisa kwekupisa: CF inovandudza kupararira kwekupisa, zvakakosha pakushandiswa kwekumhanya kukuru.

Kusashanda kweMakemikoro: CF inoramba maasidhi akasimba (kunze kwezvinokonzera oxidizer) uye yakakodzera munzvimbo dzine makemikari akaomarara.

Mashandisirwo​

Zvishandiso zveCF-PTFE zvine hunyanzvi muzvishandiso zvinoderedza kuvhunduka kwemotokari, mumidziyo ye semiconductor, uye muzvinhu zvemuchadenga, uko kugara kwenguva refu uye kutonga kupisa kwakakosha.

4. Graphite: Nyanzvi yeMafuta​

Zvimiro Zvikuru​

Kukweshana Kwakaderera: PTFE yakazadzwa neGraphite inoita kuti pave nekukweshana kwakaderera kusvika pa0.02, zvichideredza kurasikirwa kwesimba mumasisitimu anochinja-chinja.

Kugadzikana kweThermal: Graphite inowedzera kufambiswa kwethermal, ichidzivirira kuunganidzwa kwekupisa mumagetsi anomhanya zvakanyanya.

Kuenderana Nekubatana Kwakapfava: Inoderedza kupfekwa panzvimbo dzakapfava dzakadai searuminiyamu kana mhangura.

Mashandisirwo​

Zvinhu zvakagadzirwa negirafiti zvinofarirwa mumabheringi asina mafuta, macompressor seals, uye michina inotenderera uko kushanda zvakanaka uye kupisa kwakakosha.

5. Pfupiso Yekuenzanisa: Kusarudza Chinozadza Chakakodzera​

Misanganiswa yeSynergistic

Kusanganisa zvinhu zvinozadza—semuenzaniso, fiber yegirazi neMoS₂ kana fiber yekabhoni negraphite—kunogona kugadzirisa zvinhu zvakawanda. Semuenzaniso, mahybrid eGF-MoS₂ anoderedza kukweshana uku achiramba achidzivirira kupfekwa.

6. Zvinokonzera Maindasitiri Nekuchengetedzwa Kwezvinhu​

Ma PTFE composites akazadzwa anowedzera hupenyu hwechikamu, anoderedza nguva yekugadzirisa, uye anowedzera kushanda zvakanaka kwesimba. Semuenzaniso, graphite-PTFE seals mumasisitimu eLNG inodzivirira tembiricha kubva -180°C kusvika +250°C, zvichipfuura zvinhu zvemazuva ano. Kufambira mberi uku kunoenderana nezvinangwa zvehupfumi hwedenderedzwa nekuderedza marara kuburikidza nekugadzira kwakasimba.

Mhedziso​

Kusarudzwa kwefiller—girazi fiber, kabhoni fiber, kana graphite—kunotonga mashandiro ePTFE composites. Kunyange zvazvo girazi fiber richipa mutengo wakaringana uye kugara kwenguva refu, kabhoni fiber inobudirira mumamiriro ezvinhu akaoma, uye graphite inonyanya kukosha pakuzora. Kunzwisisa misiyano iyi kunogonesa mainjiniya kugadzirisa mhinduro dzekuvhara kuti dzive dzakavimbika uye dzinoshanda zvakanaka.

Sezvo maindasitiri achifambira mberi achienda kune mwero wepamusoro wekushanda, kushanda pamwe chete nenyanzvi mune zvesainzi yezvinhu kunoita kuti chigadzirwa chigadzirwe zvakanaka. Ningbo Yokey Precision Technology inoshandisa hunyanzvi hwepamusoro hwekugadzira zvinhu kuti ipe zvisimbiso zvinosangana nezvinodiwa zvakanyanya zvekushandisa mumotokari, simba, uye maindasitiri.

Mazwi akakosha: PTFE composites, sealing solutions, mainjiniya ezvinhu, mashandisirwo emaindasitiri
