Paunenge uchiongorora machira akanakisa ezvipfungaidzo zveguruva, zvinhu zviviri zvakawana kutarisisa kukuru kwekuita kwavo kwakasiyana: PTFE (Polytetrafluoroethylene) uye yakawedzera fomu, ePTFE (Yakawedzerwa Polytetrafluoroethylene). Izvi zvekugadzira zvinhu, zvinozivikanwa neakasarudzika makemikari uye emuviri zvimiro, zvakatsanangudza guruva kusefa munzvimbo dzinodiwa, zvichipa zvakanakira izvo zvinovasiyanisa kubva kune echinyakare machira sedonje, polyester, kana nyangwe akajairwa HEPA zvinhu.
PTFE, inowanzodanwa nezita rayo rekuti Teflon, fluoropolymer inopembererwa nekuda kweiyo isiri-tsvimbo zvivakwa, makemikari kuramba, uye yakakwirira-kushivirira. Muchimiro chayo mbishi, PTFE idense, yakasimba zvinhu, asi kana ikagadzirwa kuita sefa machira, inoumba yakatsetseka, yakaderera-inokwesha nzvimbo inodzinga huruva, zvinwiwa, uye zvinosvibisa. Uhu husina-kunamira hunhu hwakakosha pakusefa kweguruva: kusiyana nemachira ane porous anoteya zvimedu zvakadzika mukati mefibers (zvichitungamira kuvharika),PTFE mafiritabvumira guruva kuti riungane pamusoro, zvichiita kuti zvive nyore kuchenesa kana kuzunungusa. Iyi "yepamusoro yekurodha" ficha inogonesa kuyerera kwemhepo nekufamba kwenguva, mukana wakakosha munzvimbo-huru-huru senge nzvimbo dzekuvaka kana zvidyarwa zvekugadzira.
ePTFE, yakagadzirwa nekutambanudza PTFE kugadzira chimiro cheporous, inotora kusefa kuita kune inotevera nhanho. Maitiro ekuwedzera anoburitsa network ye microscopically diki pores (kazhinji pakati pe 0.1 ne 10 microns) uchichengetedza PTFE's inherent properties. Aya ma pores anoita sesefa chaiyo: anovharira guruva zvidimbu-kusanganisira fine particulate matter (PM2.5) uye even sub-micron particles-apo achibvumira mweya kupfuura usingadzivirirwe. EPTFE's porosity inogoneka zvakanyanya, ichiita kuti ive yakakodzera kune zvikumbiro kubva pakugara mhepo yekuchenesa (kusefa pet dander uye mukume) kuenda kudzimba dzekuchenesa maindasitiri (kutora ultrafine kugadzira byproducts).
Imwe yemabhenefiti akanyanya ePTFE uye ePTFE kusimba kwavo uye kuramba kune yakaoma mamiriro. Kusiyana nekotoni kana polyester, iyo inogona kuderera kana ichiiswa kumakemikari, unyoro, kana kupisa kwakanyanya, PTFE uye ePTFE inert kune zvakawanda zvinhu, kusanganisira acids uye zvinonyungudutsa. Dzinogona kushingirira tembiricha dzinobva -200°C kusvika 260°C (-328°F kusvika 500°F), dzichiita kuti dzive dzakanakira kushandiswa muchoto, maepoust systems, kana nzvimbo dzekunze uko mafirita anoratidzwa kumamiriro ekunze akanyanyisa. Uku kusimba kunoshandura kune hupenyu hurefu - PTFE uye ePTFE mafirita anogona kupedza mwedzi kana kunyange makore nekugadzirisa kwakakodzera, kudarika dzimwe nzira dzinoraswa dzakaita sepepa kana mafiritsi ekutanga ekugadzira.
Imwe bhenefiti ndeye yavo yakaderera yekuchengetedza zvinodiwa. Kutenda kune PTFE's isiri-tsvimbo yepamusoro, guruva zvidimbu hazvinamatire zvakasimba kune sefa zvinhu. Muzviitiko zvakawanda, kungozunungusa sefa kana kushandisa mweya wakadzvanywa zvakakwana kudzinga guruva rakaunganidzwa, kudzoreredza kushanda kwayo. Kugadziriswa uku hakungodzikisi tsvina chete asiwo kunoderedza mari yenguva refu kana ichienzaniswa nemasefa ekushandisa kamwe chete. Semuyenzaniso, mumaindasitiri vacuum cleaners, ePTFE mafirita anogona kucheneswa kakawanda asati ada kutsiviwa, zvichideredza zvakanyanya mari yekushandisa.
Kana ichienzaniswa neHEPA mafirita-yakareba ichionekwa seyegoridhe mwero weiyo yakanaka particle filtration-ePTFE inobata yayo. Nepo HEPA mafirita achitora 99.97% ye0.3-micron zvimedu, epamusoro-mhando ePTFE mafirita anogona kuwana akafanana kana kutonyanya kushanda kwemazinga. Pamusoro pezvo, ePTFE's superior airflow (nekuda kweiyo optimized pore chimiro) inoderedza kuomarara kwefan masisitimu, ichiita kuti ishande-simba kupfuura HEPA mumashandisirwo mazhinji.
Mukupedzisa, PTFE uye ePTFE zvinomira pachena semachira akasarudzika emasefa eguruva. Musanganiswa wavo wakasarudzika wekupokana kwemakemikari, kushivirira tembiricha, customizable porosity, uye kushandiswazve kunoita kuti dziite zvakasiyana-siyana zvakakwana zvemazuva ese uye kushandiswa kwemaindasitiri. Ingave iri muchimiro chePTFE chisiri chetsvimbo chekuunganidza guruva rinorema kana kuti yakawedzerwa ePTFE membrane ye-ultra-fine particle filtration, zvinhu izvi zvinopa mhinduro yakavimbika, inogara kwenguva refu yekuchengetedza mweya usina guruva uye zvinosvibisa. Kune avo vari kutsvaga sefa inoenzanisa kushanda zvakanaka, kusimba, uye kudhura-kushanda, PTFE uye ePTFE zviri pakati pesarudzo dzakanakisa dziripo.
