Polyester Txheej Txhuas Txheej Txhuas Vaj Huam Sib Luag

Txhuas puas vaj huam sib luag (ACP), ua los ntawm txhuas puas khoom (ACM), yog cov tiaj tiaj uas ua los ntawm ob txheej nyias txheej-txhuas txhuas ntawv sib txuas rau cov tub ntxhais tsis-txhuas. ACPs nquag siv rau sab nrauv cladding lossis facades ntawm cov tuam tsev, rwb thaiv tsev, thiab paib.

ACP feem ntau yog siv rau sab nrauv thiab sab hauv kev tsim vaj tsev hauv ntu lossis ntu, tsis muaj qab nthab, kos npe, lub tshuab npog, siv thawv, thiab lwm yam. , cuav qab nthab, etc. ACP kuj tseem siv dav nyob rau hauv qhov kev lag luam signage raws li kev hloov rau cov khoom hnyav, cov nqi kim dua.

ACP tau siv los ua lub teeb yuag tab sis cov khoom siv ruaj khov hauv kev tsim kho, tshwj xeeb yog kev hloov pauv zoo li kev lag luam tawm lub rooj muag khoom thiab cov ntsiab lus zoo ib ntus. Nws tau tsis ntev los no tau txais los ua cov khoom siv thim rov qab rau cov duab kos duab zoo nkauj, feem ntau nrog cov acrylic ua tiav siv cov txheej txheem zoo li Diasec lossis lwm cov txheej txheem ntsej muag. ACP cov khoom siv tau raug coj los siv hauv cov qauv nto moo xws li Spaceship Earth, VanDusen Botanical Garden, Leipzig ceg ntawm German Lub Tsev Qiv Ntawv.

Cov kev teeb tsa no ua rau pom zoo ntawm ACP los ntawm nws cov nqi, kav ntev, thiab siv tau. Nws cov yooj, lub cev nyhav, thiab yooj yim sib sau thiab kev ua haujlwm pub rau kev tsim kho tshiab nrog ua kom muaj kev nruj thiab ruaj khov. Qhov twg cov khoom siv tseem ceeb yog qhov kub nyhiab, qhov kev siv yuav tsum raug txiav txim siab. Cov txuj ci tseem ceeb ACP yog polyethylene (PE) lossis polyurethane (PU). Cov ntaub ntawv no tsis muaj cov khoom siv hluav taws zoo (FR) tshwj tsis yog muaj kev kho tshwj xeeb thiab yog li tsis tsim nyog feem ntau ua cov khoom siv ua tsev rau chaw nyob; ntau txoj kev txwv tau txwv lawv txoj kev siv tag nrho. [12] Arconic, tus tswv ntawm Reynobond hom, ceev faj tus neeg yuav khoom zeem muag. Hais txog qhov tseem ceeb, nws hais tias qhov deb ntawm lub vaj huam sib luag los ntawm hauv av yog qhov txiav txim siab ntawm "cov khoom siv twg yog kev nyab xeeb dua los siv". Hauv daim ntawv me me nws muaj duab ntawm lub tsev ntawm cov nplaim hluav taws, nrog cov lus sau "[a] sai sai thaum lub tsev siab dua cov neeg tua hluav taws, nws yuav tsum tau xeeb nrog cov khoom siv tsis tuaj yeem". Nws qhia tau hais tias Reynobond polyethylene cov khoom lag luam yog rau kwv yees li circa 10 meters; cov khoom kub nyhiab (c. 70% pob zeb hauv av) los ntawm qhov ntawd mus txog rau c. 30 meters, qhov siab tshaj ntawm tus ntaiv; thiab cov khoom lag luam European A2-rated (c. 90% mineral core) rau txhua yam saum toj no. Hauv daim ntawv qhia no, Kev Nyab Xeeb Hluav Taws Xob hauv Cov Tsev Siab: Peb Cov Hluav Taws Xob, kev qhia meej cov khoom lag luam tsuas yog muab rau ob qho khoom kawg nkaus. [13]

Cov khoom siv coj los ua ke, tshwj xeeb yog cov tub ntxhais, tau hais txog qhov ua rau muaj peev xwm ua tau rau xyoo 2017 Grenfell Ntauwd hluav taws kub hauv London, [14] ntxiv rau hauv tsev siab ua hluav taws kub hauv Melbourne, Australia; Fab Kis; Teb chaws As-lam kuj Emirates; Kaus Lim Qab Teb; thiab Tebchaws Asmeskas. [15] Cov qhov cub hluav taws-qib, xws li cov pob zeb hauv av (MW), yog lwm txoj kev xaiv, tab sis feem ntau kim dua thiab feem ntau tsis yog raws li txoj cai.

Cov ntawv ci txhuas tuaj yeem ua tiav nrog polyvinylidene fluoride (PVDF), fluoropolymer resins (FEVE), lossis pleev xim polyester. Aluminium tuaj yeem pleev xim rau hauv txhua hom xim, thiab ACPs tau tsim nyob rau hauv cov xim hlau thiab xim tsis yog xim hlau zoo li cov qauv uas qog lwm yam khoom siv, xws li ntoo lossis marble. Qhov tseem ceeb yog feem ntau tsis tshua muaj hluav taws xob polyethylene (PE), los yog kev sib xyaw ntawm cov tsis muaj hluav taws xob polyethylene thiab cov khoom siv ntxhia kom pom cov hluav taws kub retardant zog.
