Jira rePTFE, kana kuti jira re polytetrafluoroethylene, ijira rinoshanda zvakanaka rinoshandiswa zvakanyanya muminda yakawanda nekuda kwehunhu hwaro hwakanaka hwemvura isingapindi mvura, inofema, inodzivirira mhepo, uye inodziya.
Chinhu chikuru chejira rePTFE ipolytetrafluoroethylene microporous film, ine chimiro chakasiyana che microporous chine saizi ye 0.1-0.5 microns chete, iyo iri diki zvikuru pane dhayamita yemorekuru yemvura, asi yakakura kane zviuru kupfuura molekyuru yemvura. Nokudaro, jira rePTFE rinogona kudzivirira kupinda kwemadonhwe emvura uku richibvumira mhute yemvura kupfuura zvakasununguka, zvichiita kuti ive musanganiswa wakakwana wemvura isingapindi mvura uye inofema. Jira iri rinewo hunhu hwakanaka hunodzivirira mhepo, uye chimiro charo che microporous chinogona kudzivirira mhepo kupinda, nokudaro ichichengetedza kudziya mukati mechipfeko.
1. Hunhu hwepakutanga hwePTFE
PTFE yakatanga kugadzirwa neDuPont muma1940 uye inozivikanwa se "Mambo wePlastiki" nekuda kwekushanda kwayo kwakanaka. Maumbirwo ePTFE emamorekuru akagadzikana zvikuru, uye simba rekubatana pakati pemaatomu ekabhoni nemaatomu efluorine rakakwira zvakanyanya, izvo zvinopa PTFE zvinhu zvinotevera zvinoshamisa:
● Kusapinda mvura:Machira ePTFE ane hunhu hwakanaka hwemvura, uye mamorekuru emvura haakwanise kupinda pamusoro pawo, saka anowanzo shandiswa kugadzira mbatya nemidziyo isingapindi mvura.
● Kufema:Kunyangwe isingapindi mvura, machira ePTFE ane chimiro chine maburi madiki anobvumira utsi hwemvura kupfuura nepakati, zvichichengetedza nyaradzo yeanopfeka. Izvi zvinoita kuti ive sarudzo yakakodzera yezvipfeko zvemitambo zvekunze uye zvipfeko zvekudzivirira.
● Kusagona kushandisa makemikari:PTFE inodzivirira zvakanyanya makemikari mazhinji uye hainyanyi kukanganiswa nezvinhu zvinoparadza zvakaita semaacid, alkalis, uye zvinonyungudutsa.
● Kudzivirira kupisa:Machira ePTFE anogona kuramba akasimba kana tembiricha yakakwira, uye tembiricha yekushanda kwayo iri pakati pe -200°C kusvika +260°C, yakakodzera munzvimbo dzine tembiricha yakakwira kana yakaderera.
● Kukwana kwekukakavadzana kwakaderera:PTFE ine nzvimbo yakatsetseka uye ine friction coefficient yakaderera, saka inowanzoshandiswa muzvikamu zvemaindasitiri zvinoda kuderedza friction.
● Kusakwanisa kukwegura:PTFE inodzivirira zvakanyanya mwaranzi ye ultraviolet nezvimwe zvinhu zvinokanganisa nharaunda, uye haikurumidzi kukwegura mushure mekushandiswa kwenguva refu.
Pakati pazvo, chinhu chinonyanya kuzivikanwa nejira rePTFE ikudzivirira kwayo ngura nemakemikari. Rinogona kudzivirira kukuvadzwa kweasidhi yakasimba, alkalis yakasimba nezvimwe zvinhu zvemakemikari, saka rinoshandiswa zvakanyanya muzvipfeko zvakakosha zvakaita sezvipfeko zvekudzivirira zvenyukireya, zvebhayoloji nemakemikari uye zvipfeko zvekudzivirira zvemakemikari. Pamusoro pezvo, jira rePTFE rinewo mabasa ekurwisa mabhakitiriya, antistatic, virus blocking nezvimwe, zvichiita kuti rive rakakoshawo mukuchengetedza kurapa.
Mukushandiswa chaiko, jira rePTFE rinosanganiswa nenylon, polyester nemamwe machira kuburikidza nemaitiro akakosha e lamination kugadzira jira rine macomposite maviri-mu-mumwe kana matatu-mu-mumwe. Jira iri rine macomposite haringochengetedzi chete kushanda kwakanaka kwePTFE firimu, asiwo rine kunyaradzwa uye kugara kwenguva refu kwemamwe machira.
2. Minda yekushandisa machira ePTFE
Nekuda kwehunhu hwakasiyana hwemachira ePTFE, yakashandiswa zvakanyanya muminda yakawanda:
● Zvipfeko zvekunze:Machira ePTFE anowanzo shandiswa kugadzira majaketi, mabhurugwa neshangu dzisingapindi mvura uye dzinofema, zvakakodzera mitambo yekunze yakaita sekukwira makomo nekutsvedza muchando.
● Zvipfeko zvekudzivirira zvemaindasitiri:Kusabatwa kwayo nemakemikari uye kusabatwa nekupisa kunoita kuti ive chinhu chakanakira zvipfeko zvekudzivirira mumaindasitiri emakemikari, peturu nemamwe.
● Zvinhu zvekurapa:Machira ePTFE anoshandiswa kugadzira magown ekuvhiya, ma wraps ekuuraya utachiona nezvimwe zvinhu zvekurapa kuitira kuti pave nenzvimbo isina utachiona.
● Zvinhu zvekusefa:Maumbirwo ePTFE ane maburi madiki anoita kuti ive sefa inoshanda zvakanaka, iyo inoshandiswa zvakanyanya mukuchenesa mweya, kugadzirisa mvura nedzimwe nzvimbo.
● Ndege:Kudzivirira tembiricha yePTFE uye kusimba kwekukweshana kwakaderera zvinoita kuti ishandiswe mumunda wendege, senge zvisimbiso nezvinhu zvekudzivirira.
3. Kudzivirirwa kwezvakatipoteredza kwemachira ePTFE
Kunyange zvazvo machira ePTFE aine zvakanakira zvakawanda, kuchengetedzwa kwawo kwezvakatipoteredza kwakakwezvawo kutariswa kukuru. PTFE chinhu chinonetsa kushatisa, uye chichava nemhedzisiro yakati panharaunda mushure mekuraswa. Saka, maitiro ekudzokorodza uye kurasa machira ePTFE ave nyaya yakakosha. Parizvino, mamwe makambani ari kugadzira zvinhu zvePTFE zvinogona kudzokororwa kuti aderedze kukanganisa kwazvinoita panharaunda.
4. Pfupiso
Machira ePTFE ave chinhu chinodiwa pakushandiswa kwepamusoro-soro nekuda kwekusapinda mvura zvakanaka, kufema zvakanaka, kusapindirana nemakemikari, kusapindirana nekupisa uye zvimwe zvinhu. Ingava mitambo yekunze, dziviriro yemaindasitiri, kana nzvimbo dzekurapa nedzemuchadenga, machira ePTFE aratidza zvakanakira zvawo zvakasiyana. Zvisinei, nekuwedzera kweruzivo rwezvakatipoteredza, nzira yekugadzirisa nayo marara ePTFE ichave chinhu chikuru mukutsvaga nekuvandudza mune ramangwana.
