Kunzwisisa kwakadzama kwemusimboti wekushanda uye kushandiswa kwefirimu rinofema remvura
Mvura isingapindi mvura inofema firimu chigadzirwa chekushandisa chinobva kune membrane yekuparadzanisa tekinoroji. Ifirimu rakagadzirwa nemaitiro akakosha uye rine sarudzo yekupinda. Inogona kubvumira mamwe magasi madiki pane aperture yefirimu rinofemerwa nemvura kuti ipfuure nepasi pehunhu hwayo, uye haikwanise kubvumidza zvimwe zvinhu zvakaita semadonhwe emvura akakura kupfuura aperture yefirimu rinofema risingapindi mvura kuti ipfuure. Izvo chaizvo nekuda kwechimiro chemufirimu unofema wemvura unogona kupfuura mamwe mamorekuru madiki, uye mamwe mamorekuru akakura haakwanise kupfuura nemufirimu rinofema remvura, saka kubva kuma1960 ezana ramakore rapfuura, firimu rinofema remvura rakagadzirwa nekukurumidza. Parizvino, kune kunyanya PTFE, PES, PVDF, PP, PETE uye mamwe masefa membranes, nekuda kwekugadzikana kwakanaka kwemakemikari ePTFE zvinhu, zvakasikwa hydrophobic zvimiro uye zvinoshandiswa mukufamba kwese kwehupenyu.
Kushanda musimboti wekudzivirira mvura inofema membrane
Mumamiriro emhute yemvura, dhayamita yemvura mhute mamorekuru inongosvika 0.0004 microns, uye dhayamita diki yemadonhwe emvura inenge 20 microns. Kuvepo kwepolymer inofema layer ine micropores mumhepo isingafemeki firimu inogonesa mamorekuru emhute ari mumadziro kuti abudise zvakanaka kuburikidza ne microporous membrane kuburikidza neiyo diffusion musimboti, zvinobudirira kuderedza dambudziko re condensation pamadziro ekunze. Nekuda kwehupamhi hwakakura hwemvura yemvura kana madonhwe emvura kunze kwemadziro, mamorekuru emvura haakwanise kupinda kubva pamvura mabhesi kuenda kune rimwe divi, izvo zvinoita kuti firimu rinofema risapinda mvura.
Mumamiriro ezvinhu akajairwa, zvishandiso zvakawanda uye mashandisirwo azvo zvinoda nzvimbo yakavharwa yekuvhara, iyo isingagone kukanganiswa neguruva rekunze, mvura, uye mabhakitiriya. Kana iyo dhizaini yakavharwa zvakanyanya, pasi pechinangwa chemamiriro ekunze tembiricha uye shanduko yelatitude, zvinotungamira mukumanikidzwa kuchinja mukati memidziyo, kazhinji shanduko iyi yekumanikidza inoburitsa imwe yekusimbisa mhedzisiro, iyo inoparadza nzvimbo dzakasimba dzechigadzirwa chemidziyo uye. mukati. Iko kushandiswa kwe ePTFE isina mvura inofema membrane inogona kuramba ichienzanisa musiyano wekumanikidza wemidziyo, kuderedza mutengo wechikamu chekugadzira, uye kuve nechokwadi chekuvimbika kwechigadzirwa.
ePTFE isingapindi mvura inofema firimu maitiro
Isingapindi mvura: 0.1-10μm microhole, iyo aperture iri isingasviki 10,000 nguva mabheji emvura, kuitira kuti mvura isapfuure, inodzivirira zvinodzivirira zvikamu, kudzivirira kukukurwa kwemvura, kuvandudza hupenyu hwechigadzirwa.
Air permeability: iyo micropore dhayamita yakakura ka700 kupfuura mhute yemvura, isingapindi mvura panguva imwe chete, ichibvumira mhepo kuti ipfuure zvakanaka, inogona kunyatso kupisa kupisa, kudzivirira mukati memadziro echigadzirwa mhute, kuenzanisa mukati uye kunze kwenzvimbo kumanikidza.
Dziviriro yeguruva: Iyo microporous chiteshi inoumba mesh matatu-dimensional chimiro mufirimu, uye iyo yunifomu uye yakaomesesa kugovera kwema micropores inoita kuti guruva risanganise chipingamupinyi, kuitira kuti uwane inoshanda yekudzivirira guruva, uye hushoma hunogona kutora 0.1μm zvimedu.
