Nyob rau hauv niaj hnub tsim thiab architectural kho kom zoo nkauj, PET nplooj ntawv yog dav siv nyob rau hauv acoustic engineering, hniav panels, signage thiab zaub fixtures, thiab muaj kev tiv thaiv vim lawv zoo xws li lub teeb yuag, siab zog, zoo huab cua tsis kam, yooj yim ntawm kev ua, thiab recyclability. Txawm li cas los xij, nyob rau hauv ib puag ncig kev thov sib txawv, cov teeb meem xws li kev khawb tsis txaus, cov nplaim hluav taws xob tsawg, thiab cov brittleness ntau ntxiv tuaj yeem cuam tshuam rau cov neeg siv kev paub thiab kev ua neej. Txhawm rau hais txog cov kev mob tshwm sim no, kev lag luam tau tsim cov txheej txheem kev daws teeb meem los txhim kho tag nrho cov kev hloov pauv ntawm PET nplooj ntawv.
Txhawm rau daws qhov tsis txaus ntawm kev khawb tsis txaus thiab qhov tawv tawv, cov txheej txheem kev kho deg tuaj yeem ua haujlwm. Piv txwv li, los ntawm txheej txheej ntawm daim ntawv PET nrog hnav- txheej tiv thaiv (xws li polyurethane lossis acrylic resin system), lossis los ntawm kev siv cov plasma- txhim kho cov tshuaj vapor deposition (PECVD) los tsim cov nano- nplai tawv zaj duab xis, Vickers hardness tuaj yeem nce ntxiv mus rau saum 3H ntawm kev pheej hmoo txhua hnub. Txoj kev no tuav cov pob tshab thiab kev ua tiav ntawm cov khoom siv hauv paus thaum ntsuas cov hniav zoo nkauj thiab ua haujlwm ntev, ua rau nws tsim nyog rau siab -ntau zaus hu rau daim ntawv thov xws li cov khoom txee thiab cov thawv teeb pom kev zoo.
Hais txog kev txhim kho cov nplaim hluav taws, qhov no tuaj yeem ua tiav los ntawm kev sib xyaw lossis nplaim nplaim hluav taws xob- cov txheej txheem retardant. Kev sib xyaw bromine-raws li, phosphorus-raws li, lossis nitrogen-raws li nplaim hluav taws nrog PET matrix thaum lub sij hawm granulation, ua ke nrog cov txheej txheem extrusion optimized, tuaj yeem ua kom cov ntawv ua tau raws li UL94 V-0 lossis GB 8624 B1 cov qauv, txaus siab rau cov chaw tsheb thauj mus los thiab kev nyab xeeb. Rau cov ntawv uas twb tau tsim lawm, intumescent nplaim-retardant coatings kuj tuaj yeem siv los ntawm dipping lossis txau. Thaum raug hluav taws kub, cov coatings no tsim ib txheej char uas insulates tiv thaiv tshav kub thiab oxygen, sib npaug ib puag ncig tiv thaiv thiab yooj yim ntawm theem nrab ua.
Txhawm rau hais txog qhov ua kom muaj zog ntxiv hauv qhov qis- qhov kub thiab txias, kev hloov pauv copolymer tuaj yeem siv los qhia cov kab hloov pauv yooj yim lossis PET / PE sib xyaw thev naus laus zis tuaj yeem ua haujlwm los txhim kho qhov hloov pauv ntawm cov saw hlau molecular, tso cai rau cov khoom kom muaj kev cuam tshuam zoo ntawm qhov kub thiab txias li -20℃lossis qis dua. Qhov kev daws teeb meem no tshwj xeeb tshaj yog tsim rau cov ntawv thov xws li cov chaw txias txias thiab cov pa taws sab nraum zoov hauv thaj chaw txias heev, tiv thaiv kev tawg thiab tsis ua haujlwm vim qhov kub thiab txias poob. Hauv cov ntawv thov acoustic, txhawm rau hais txog qhov nqaim lub suab nqus spectrum ntawm cov PET ntshiab vaj huam sib luag, tus qauv tsim cov qauv sib xyaw ua ke tuaj yeem ua haujlwm. Qhov no suav nrog kev sib xyaw ua ke ntawm fiber ntau suab-absorbing txheej nyob rau sab nraum qab ntawm lub vaj huam sib luag los yog siv cov kab noj hniav resonance qauv kom ua tiav cov suab nrov nrov. Ib txhij, lub siab flatness thiab noo noo tsis kam ntawm PET panels kom ruaj khov acoustic tsis nyob rau hauv cov av ntub los yog huv si.
Tsis tas li ntawd, txhawm rau ua kom tau raws li qhov xav tau ntawm kev tiv thaiv ib puag ncig thiab kev lag luam ncig, kaw - lub voj voog rov ua dua tshiab tuaj yeem tsim. Los ntawm kev txheeb xyuas qhov muag thiab yaj rov ua dua, pov tseg PET panels tuaj yeem hloov mus rau hauv cov khoom siv rov ua dua tshiab rau kev tsim cov khoom tsis yog- cov khoom noj khoom haus, yog li txo cov pa roj carbon monoxide.
Hauv cov ntsiab lus, los ntawm kev txhim kho saum npoo, kev hloov kho nplaim hluav taws xob, kev ua kom zoo dua qub, thiab kev sib xyaw ua ke, cov ntawv thov cov nyom ntawm PET panels tau hais txog qhov systematically, tso cai rau lawv tswj hwm qhov sib npaug ntawm kev ua tau zoo thiab kev nyab xeeb hauv cov xwm txheej xav tau ntau dua, muab cov vaj huam sib luag txhim khu kev qha rau siab -kawg tsim thiab lub tsev ntsuab.
