Zvivako zvesimbi zvakashandiswa kwemireniyamu.Vanhu veko pavaida pokugara isingaremi uye yakanaka, machira aigadzirwa nematehwe emhuka uye zvinhu zvinotakurika zviri nyore ndiwo ndiwo ainyanya kushanda.KuRoman Colosseum, Velarium inodzokororwa yakapa shading kuti iwedzere kugadzikana muoni.Iye zvino, ethylene tetrafluoroethylene (ETFE) iri kupa mikana mitsva.
Chigadzirwa chitsva mukati meindastiri, ETFE ipurasitiki-yakavakirwa fluorine inoramba yakasimba kune dzakasiyana siyana tembiricha uye inodzivirira zvakanyanya mukuora.Yakagadzirwa kubva ku polytetrafluoro-ethylene (PTFE)-inozivikanwawo sepolymer-yakasimba, isingaremi, isingadziviriri moto membrane iyo yakatanga kugadzirirwa zvipfeko zvekuongorora nzvimbo, asi yakazoshandiswa pakugadzira zvigadziro uye mavuropu akajeka.
Chii chinonzi ETFE?Kunyange zvazvo girazi zvivako zvinopa kuenzaniswa kwechiedza chezuva uye kuvhara, ETFE inogara yakasimba, yakajeka, uye yakanyanya kureruka-inenge imwe muzana yehuremu hwegirazi.Pakutanga yakashandiswa mukushandiswa kwekurima, ETFE yave ichishandiswa pamapurojekiti epamusoro akadai seEden Project botanical attraction (Cornwall, England), Allianz Arena (kumusha kwenhabvu FC Bayern Munich), uye Beijing National Aquatics Center — ine mukurumbira. Mvura Cube inoratidzwa paMitambo yeZhizha ya2008.Firimu reETFE rave kutorwa sechinhu chepamusoro chekuvharisa kwakajeka maapplication kubva padenga kusvika pakuvaka façade kune echinyakare skylight application kune refu-span zvivakwa.
Zvishoma zvekuvaka zvinogona kuenderana neETFE nekuda kwayo dhizaini inoshanduka uye kukosha kwekuita.KuChina yeNantong Park Bon-Garden Greenhouse, kushanda kwemafuta uye mwenje wekufambisa zvivakwa zvinotsigira kurima horticulture ichiri kuwana yakasarudzika yakavhenekerwa dome dhizaini.KuEmpire City Casino kuYonkers Raceway muNew York, porte-cochere ine 1020-m.2(11,000-sf) pneumatic ETFE film roofing system inoratidza kugona kwechinyorwa kusangana neakasarudzika uye zvinoshanda zvinodikanwa-zvichipa kwete chete chinobata maziso chekugadzira chinhu, asiwo pekugara uye mumvuri kune varimo vane tarisiro huru yekunyaradza.
ETFE zvakare imwe yeakanyanya kureruka uye akajeka ekupfeka zvinhu zviripo.Nekuda kwekudzika kwayo coefficient of friction, hapana huruva kana tsvina inonamira pairi.Sezvo iri ultraviolet (UV) iri pachena, haibvisi ruvara kana kuderera mukufamba kwenguva.Chigadzirwa chakasimba, zvigadzirwa zveETFE zvinogona kugadzirwa zvakare kuita zvigadzirwa zvitsva zveETFE senge tubing components, waya, kana castings.
KuNanton Park Bon-Gardens Greenhouse kuChina, musangano wepadenga unosanganisira ethylene tetrafluoroethylene (ETFE) maitiro emufirimu anobatsira mukusimukira kwehorticulture uye inoyevedza inoyevedza.
Maitiro ekuitaETFE firimu rinounza akawanda mabhenefiti kune vanogara uye muridzi wechivako.Iyo firimu inogona kuve pakati pe90 ne95 muzana yakajeka, ichibvumira kutapurirana kweUV uye photosynthesis yezvekurima zvekushandisa.Iyo solar performance range yeETFE firimu masisitimu zvakare inochinjika, sezvo ichigona kubatanidza akawanda frit mapatani pane imwe kana akawanda akaturikidzana.
Yakajairwa kana tsika yakadhindwa mapatani uye huwandu hwemavara hunogona kuiswa panguva yeextrusion process kuti ipe dhizaini kuenderera pamwe neiyo yese chimiro uye kubatsira kune solar control zvivakwa.ETFE mafirimu zvakare akanyanya elastic.Kusvika ku600 muzana pakupwanyika, ivo vachiri kusimba muchimiro.Kusimba kwesimba pamuganho we elasticity / plasticity ndeye 21 kusvika 23 N/mm2(3045 kusvika 3335 lbf/si), asi kusimba kwesimba kusvika pakupwanyika i52 N/mm2(7542 lbf/si).Pakuverenga kwemaitiro, muganho we15 N/mm2(2175 lbf/si) inoonekwa sefungidziro yechokwadi.
ETFE haidzikisi pasi pekuratidzwa kusvibiswa kwezvakatipoteredza, UV chiedza, makemikari ane hutsinye, kana kutonhora kwakanyanya, zvichiita kuti ive chinhu chinogara kwenguva refu.ETFE firimu rinewo nezve 70 muzana acoustic transmission, zvichiita kuti ive yakanakira mapurojekiti anotarisira ruzha rukuru.Munguva yekugadzira dhizaini, kutapurirana kwenzwi kunofanirwa kutariswa, sezvo kuchizonyatso fambisa ruzha kupfuura iyo ETFE system uye kune iri pedyo zvivakwa.
Kubva pakubudiswa kwefirimu kuenda kune imwe nzvimbo, ETFE inogadzikana uye ine simba-inoshanda.Kuenzaniswa nezvimwe zvinhu zvekupfeka, iyo dhizaini-yekuvaka maitiro inosiya kabhoni diki tsoka.ETFE masisitimu anosanganisira zvinhu zvine simba rakadzika rakaiswa simba rinodzikiswa uye rinoshandiswazve.Iyo yakaderera kunyorovesa tembiricha yeETFE firimu inoita kuti maitiro ekudzokorodza iyo firimu ishande uye ine hupfumi.ETFE inowedzerawo kuvhara uye kupenya kwemasikati, zvichiita kuti chivakwa chishande nesimba pasi rose.Iyo zvakare ine huremu huremu kana ichienzaniswa nezvinhu zvinokwikwidza, inobvumira masisitimu ekutsigira masisitimu uye nheyo dzekongiri kuti dzigadzirwe zvinobudirira uye zvinodhura, zvichibatsira mukuderedzwa kwekabhoni tsoka.
