PTFE machira, kana kuti polytetrafluoroethylene jira, ibasa repamusoro-soro rinoshanda rinoshandiswa zvakanyanya muminda yakawanda nekuda kwekunakisisa kwemvura, kufema, mhepo, uye inodziya.
Nheyo yemucheka wePTFE ndeye polytetrafluoroethylene microporous film, ine yakasarudzika microporous chimiro ine pore saizi ye 0.1-0.5 microns chete, iyo idiki zvakanyanya kupfuura dhayamita yemorekuru wemvura, asi zviuru zvenguva yakakura kupfuura mvura mhute molecule. Nokudaro, jira rePTFE rinogona kunyatsovhara kupinda kwemadonhwe emvura uku richibvumira mhute yemvura kuti ipfuure zvakasununguka, ichiwana kusanganiswa kwakakwana kwemvura uye kufema. Iri jira rinewo zvinhu zvakanaka zvisingapindi mhepo, uye chimiro chayo che microporous chinogona kudzivirira kudzivirira mhepo, nokudaro kuchengetedza kudziya mukati menguvo.
1. Zvinhu zvinokosha zvePTFE
PTFE yakatanga kuvandudzwa neDuPont muma1940 uye inozivikanwa se "King of Plastics" nekuda kwekuita kwayo kwakanaka. Iyo molecular chimiro chePTFE yakagadzikana zvakanyanya, uye chisungo chesimba pakati pekabhoni atomu nemaatomu efluorine chakakwira zvakanyanya, izvo zvinopa PTFE zvinotevera zvinoshamisa zvivakwa:
● Kudzivirira mvura:Machira ePTFE ane hunhu hwakanaka hwekudzivirira mvura, uye mamorekuru emvura haakwanise kupinda pamusoro pawo, saka anowanzo shandiswa kugadzira zvipfeko nemidziyo isingapinde mvura.
● Kufema:Kunyangwe isina mvura, machira ePTFE ane microporous chimiro chinobvumira mhute yemvura kupfuura, kuchengetedza kunyaradza kweanopfeka. Ichi chivakwa chinoita kuti ive sarudzo yakanakira yekunze zvipfeko zvemitambo uye zvipfeko zvekudzivirira.
● Chemical resistance:PTFE inoshingirira zvakanyanya kumakemikari mazhinji uye inenge isingabatwe nezvinhu zvinopisa zvakaita seasidhi, alkali, uye zvinonyungudutsa.
● Kuramba tembiricha:Micheka yePTFE inogona kuramba yakagadzikana pakupisa kwakanyanya, uye kushanda kwayo kwekushisa kunobva -200 ° C kusvika + 260 ° C, inokodzera nzvimbo dzakakwirira kana dzakaderera.
● Low friction coefficient:PTFE ine nzvimbo yakatsetseka uye yakadzika kwazvo friction coefficient, saka inowanzoshandiswa munzvimbo dzeindasitiri dzinoda kuderedza kukwesha.
● Kuramba kuchembera:PTFE inopikisa zvakanyanya kune ultraviolet mwaranzi uye zvimwe zvakatipoteredza, uye haitani kuchembera mushure mekushandisa kwenguva refu.
Pakati pavo, iyo inonyanya kukosha yePTFE jira ndeyemakemikari ayo ekuora kwekudzivirira. Inogona kudzivisa kukukurwa kweasidhi yakasimba, alkali yakasimba uye zvimwe zvinhu zvemakemikari, saka inoshandiswa zvakanyanya muzvipfeko zvakakosha senyukireya, biological uye makemikari ekudzivirira zvipfeko uye zvipfeko zvinodzivirira zvemakemikari. Mukuwedzera, PTFE jira rinewo antibacterial, antistatic, virus blocking uye mamwe mabasa, zvichiita kuti zvive zvakakoshawo mumunda wekuchengetedzwa kwezvokurapa.
Mumashandisirwo chaiwo, jira rePTFE rinosanganiswa nenylon, polyester uye mamwe machira kuburikidza neanokosha lamination process kugadzira maviri-in-one kana matatu-in-one composite jira. Iri jira rakaumbwa haringochengetedzi kuita kwakanakisa kwePTFE firimu, asi zvakare rine kunyaradza uye kusimba kwemamwe machira.
2. Nzvimbo dzekushandisa dzePTFE machira
Nekuda kwezvakasiyana zvivakwa zvePTFE machira, yakashandiswa zvakanyanya mundima dzakawanda:
● Zvipfeko zvekunze:Micheka yePTFE inowanzoshandiswa kugadzira majaketi asingapindi mvura uye anofema, mabhurugwa neshangu, akakodzera mitambo yekunze yakadai sekukwira makomo uye skiing.
● Mbatya dzinodzivirira mumaindasitiri:Kupokana kwayo kwemakemikari uye kupisa kwekushisa kunoita kuti ive chinhu chakanakira zvipfeko zvekudzivirira mumakemikari, petroleum uye mamwe maindasitiri.
● Mishonga yekurapa:Machira ePTFE anoshandiswa kugadzira machira ekuvhiya, disinfection wraps uye zvimwe zvekurapa kuti ive nechokwadi chenzvimbo isina hutachiona.
● Sefa zvinhu:Iyo microporous chimiro chePTFE inoita kuti ive inoshanda sefa zvinhu, iyo inoshandiswa zvakanyanya mukunatswa kwemhepo, kurapwa kwemvura uye mamwe minda.
● Muchadenga:PTFE's tembiricha kuramba uye yakaderera friction coefficient inoita kuti ishandiswe mumunda wemuchadenga, sezvisimbiso uye zvekudzivirira.
3. Kuchengetedzwa kwezvakatipoteredza kwePTFE machira
Kunyangwe machira ePTFE aine akawanda mabhenefiti, kuchengetedza kwavo kwezvakatipoteredza kwakakwezvawo kutarisisa. PTFE chinhu chakaoma-ku-degrade, uye chichava nekukanganisa nharaunda mushure mekuraswa. Naizvozvo, maitiro ekudzokorodza nekurasa machira ePTFE yave nyaya yakakosha. Parizvino, mamwe makambani ari kugadzira zvigadziriso zvePTFE zvinhu kuti zvideredze maitiro avo pane zvakatipoteredza.
4. Pfupiso
PTFE machira akave chinhu chinodiwa kune akawanda ekupedzisira-ekupedzisira maapplication nekuda kweakanakisa kusapinda kwemvura, kufema, makemikari kuramba, tembiricha kuramba uye zvimwe zvinhu. Ingave mitambo yekunze, kuchengetedzwa kwemaindasitiri, kana minda yezvokurapa neyemuchadenga, machira ePTFE aratidza zvawo zvakanakira. Nekudaro, nekuwedzera kwekuziva kwezvakatipoteredza, maitiro ekuita zvirinani nekuraswa kwePTFE machira anozove ekutarisa kwekutsvagisa nekusimudzira.
