Niaj hnub no peb muaj batch ntawm txias cia panels xa mus rau Australia.Nws yog peb cov neeg siv khoom ntev uas tau koom tes nrog peb txij li thaum ntxov ntawm lub tuam txhab thiab yuav polyurethane panels los ntawm peb.

Dab tsi yog cov txiaj ntsig ntawm kev siv cov khoom txias txias rau kev tsim kho txias?

Qhov zoo ntawm kev cia txias yog cuam tshuam nrog lub tub yees siv thiab cov ntaub ntawv siv.Thaum tsim cov chaw cia txias, yuav luag 90% ntawm peb lub tshuab txias cia txias siv lub rooj tsavxwm txias, vim nws muaj qhov zoo hauv qab no.

1. Lub rooj tsav xwm txias txias muaj cov yam ntxwv ntawm kev muaj zog tiv thaiv deformation, tsis yooj yim rau tawg, thiab ruaj khov.Lub pore qauv ntawm cov khoom siv polyurethane yog ruaj khov thiab pib kaw, uas tsis yog tsuas yog muaj cov thermal rwb thaiv tsev zoo thiab kev ua haujlwm tsis zoo, tab sis kuj muaj lub suab zoo nqus.Raws li kev siv thiab kev saib xyuas, qhov nruab nrab lub neej ua haujlwm ntawm cov txheej txheem polyurethane ua npuas ncauj rwb thaiv tsev feem ntau tuaj yeem ncav cuag ntau tshaj 30 xyoo.Nws tuaj yeem siv tau raws li kev siv ib txwm siv thaum lub neej ntawm cov qauv, hauv qhuav, ntub dej lossis galvanic corrosion, thiab tus nqi ntxiv yuav ua kom sov li kab, fungal lossis algal ua npuas ncauj yog kim dua li lwm cov khoom siv rwb thaiv tsev thiab txo qhov tseem ceeb. hauv cov nqi cua txias.

2. Lub rooj tsav xwm txias txias muaj cov thermal conductivity coefficient thiab cov dej tsis zoo thiab kev ua haujlwm tsis zoo: cov khoom siv tawv polyurethane muaj cov thermal conductivity coefficient thiab kev ua haujlwm zoo thermal.Polyurethane txoj kev loj hlob muaj kev ua haujlwm ntawm cov dej-pov thawj thiab dej tsis zoo.Thaum lub kaw cell ratio ntawm nruj polyurethane ntau tshaj 90%, nws yog ib tug hydrophobic tsom xam cov ntaub ntawv, uas yuav tsis nce vim noo noo nqus thiab thermal conductivity, thiab yuav tsis muaj to ntawm phab ntsa.

3. Lub rooj tsav xwm txias txias muaj cov yam ntxwv ntawm kev tiv thaiv hluav taws, nplaim hluav taws, tiv thaiv kub thiab zoo suab rwb thaiv tsev.Nrog rau qhov sib ntxiv ntawm cov nplaim hluav taws, polyurethane yog cov khoom siv hluav taws xob hluav taws xob tua tus kheej nrog qhov muag muag ntawm ntau dua 250 degrees Celsius thiab tsuas yog decompose ntawm qhov kub siab dua.Tsis tas li ntawd, cov tshauv tuaj yeem tsim rau ntawm qhov chaw ntawm cov npuas dej thaum lub polyurethane kub hnyiab, pab tiv thaiv cov npuas dej hauv qab.Nws tuaj yeem tiv thaiv kev sib kis ntawm hluav taws, thiab polyurethane tsis tsim cov pa phem ntawm qhov kub thiab txias.
