Tensile qauv tau siv rau ntau txhiab xyoo.Thaum cov neeg hauv paus txawm xav tau chaw nkaum uas yog lub teeb yuag thiab lub suab zoo, cov ntaub uas ua los ntawm cov tsiaj nkaum thiab cov khoom thauj tau yooj yim yog cov kev daws teeb meem zoo tshaj plaws.Ntawm Roman Colosseum, ib lub retractable Velarium muab shading rau cov neeg saib zoo dua.Tam sim no, ethylene tetrafluoroethylene (ETFE) tab tom muab txoj hauv kev tshiab.
Ib yam khoom tshiab nyob rau hauv kev lag luam, ETFE yog fluorine-raws li yas uas tseem muaj zog nyob rau hauv ntau qhov kub thiab txias thiab tiv taus corrosion heev.Nws tau tsim los ntawm polytetrafluoro-ethylene (PTFE)-tseem hu ua polymer-lub zog, hnav, hluav taws kub-retardant ntaub membrane uas yog tsim los rau qhov chaw tshawb nrhiav khaub ncaws, tab sis tom qab siv rau kev siv vaj tse thiab lub hnab ntawv pob tshab.
ETFE yog dab tsi?Thaum cov qauv iav muab piv rau lub hnub ci sib kis thiab rwb thaiv tsev, ETFE yog qhov ruaj khov, pob tshab dua, thiab sib dua - nws yog kwv yees li ib feem pua qhov hnyav ntawm iav.Thaum pib siv rau hauv kev ua liaj ua teb, ETFE tau txij li thaum tau siv rau hauv cov haujlwm siab xws li Eden Project botanical attraction (Cornwall, England), Allianz Arena (lub tsev rau kev ncaws pob FC Bayern Munich), thiab Beijing National Aquatics Center - lub npe nrov Dej Cube tau nthuav tawm ntawm 2008 Summer Games.ETFE zaj duab xis yog tam sim no suav hais tias yog cov khoom siv zoo tshaj plaws rau kev siv pob tshab cladding xws li lub ru tsev mus rau façade kev tsim kho mus rau kev siv skylight ib txwm siv rau cov qauv ntev.
Ob peb cov ntaub ntawv hauv tsev tuaj yeem phim ETFE rau nws cov qauv tsim thiab kev ua tau zoo.Rau Tuam Tshoj Nantong Park Bon-Garden Tsev cog khoom, cov khoom siv thermal kev ua tau zoo thiab lub teeb kis tau tus mob txhawb kev vam meej horticulture thaum tseem ua tiav ib qho tshwj xeeb illuminated dome tsim.Ntawm Empire City Casino ntawm Yonkers Raceway hauv New York, qhov chaw nres nkoj-cochere nrog 1020-m2(11,000-sf) pneumatic ETFE zaj duab xis vov tsev qhia cov khoom siv lub peev xwm kom ua tau raws li qhov tshwj xeeb zoo nkauj thiab cov kev xav tau - muab tsis tau tsuas yog lub qhov muag pom kev tsim, tab sis kuj muaj vaj tse thiab ntxoov ntxoo rau cov neeg nyob nrog kev cia siab rau kev nplij siab.
ETFE kuj yog ib qho ntawm cov khoom siv hnyav tshaj plaws thiab pob tshab cladding muaj.Vim nws cov coefficient tsawg ntawm kev sib txhuam, tsis muaj plua plav lossis av nplaum rau nws.Raws li nws yog ultraviolet (UV) pob tshab, nws tsis muaj xim tsis muaj xim lossis tsis muaj zog hauv lub sijhawm.Cov khoom lag luam muaj txiaj ntsig zoo, kev tsim cov khoom lag luam ntawm ETFE tuaj yeem muab rov qab rau hauv ETFE cov khoom tshiab xws li cov khoom siv tubing, cov xov hlau, lossis cov castings.
Ntawm Nanton Park Bon-Gardens Greenhouse hauv Suav teb, lub ru tsev sib dhos uas suav nrog ethylene tetrafluoroethylene (ETFE) zaj duab xis qhov kev ua tau zoo ua rau muaj kev vam meej horticulture thiab lub cim zoo nkauj.
Cov yam ntxwv ua haujlwmETFE zaj duab xis coj tau ntau yam txiaj ntsig rau cov neeg nyob thiab tus tswv tsev.Cov yeeb yaj kiab tuaj yeem nyob nruab nrab ntawm 90 thiab 95 feem pua pob tshab, tso cai rau UV kis thiab photosynthesis rau kev ua liaj ua teb.Lub hnub ci kev ua tau zoo ntawm ETFE zaj duab xis tshuab kuj hloov pauv tau, vim tias lawv tuaj yeem sib xyaw ntau cov qauv frit ntawm ib lossis ntau txheej.
Cov qauv luam tawm los yog kev cai luam tawm thiab ntau yam xim tuaj yeem siv tau thaum lub sij hawm extrusion txheej txheem los muab cov qauv tsim txuas ntxiv nrog rau cov qauv tsim thiab pab txhawb rau cov khoom siv hnub ci.ETFE films kuj tsis tshua muaj elastic.Txog li 600 feem pua ntawm qhov tawg, lawv tseem muaj kev tiv thaiv zoo.Lub zog tensile ntawm qhov txwv ntawm elasticity / yas yog 21 txog 23 N / mm2(3045 txog 3335 lbf / si), tab sis lub zog tensile rau tawg taw tes yog 52 N / mm2(7542 lbf/si).Rau kev suav cov qauv, kev txwv ntawm 15 N / mm2(2175 lbf / si) yog suav tias yog kev kwv yees qhov tseeb.
ETFE tsis degrade nyob rau hauv raug rau ib puag ncig muaj kuab paug, UV teeb, hnyav tshuaj, los yog huab cua kub, ua rau nws yog ib tug tshwj xeeb cov khoom siv ntev.ETFE zaj duab xis kuj muaj txog 70 feem pua ntawm kev sib kis acoustic, ua rau nws zoo tagnrho rau tej yaam num uas xav kom nrov nrov.Thaum lub sij hawm tsim kev tsim kho, lub suab kis tau tus mob yuav tsum tau txiav txim siab, raws li nws yuav kis tau suab dhau ntawm ETFE system thiab rau cov khoom nyob ze.
Los ntawm extruding ntawm zaj duab xis mus rau kev thauj mus los ntawm qhov chaw, ETFE muaj kev ruaj khov thiab siv zog.Piv nrog rau lwm cov ntaub ntawv cladding, cov txheej txheem tsim-tsim tawm cov pa roj carbon me me.ETFE cov tshuab suav nrog cov khoom siv nrog lub zog qis uas yog demountable thiab recyclable.Qhov qis softening kub ntawm ETFE zaj duab xis ua rau cov txheej txheem ntawm kev rov ua dua cov yeeb yaj kiab zoo thiab kev lag luam.ETFE kuj tseem txhim khu kev rwb thaiv tsev thiab nruab hnub nrig, ua rau lub tsev lub zog txuag hluav taws xob.Nws kuj tseem yog qhov hnyav hnyav piv rau cov khoom sib tw, tso cai rau cov txheej txheem kev txhawb nqa substructure thiab cov pob zeb ua vaj tse tsim kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo, ua rau txo qis cov pa roj carbon hneev taw.
