Puf vaj huam sib luag siv dav hauv kev tsim kho, chaw cia khoom txias, tsev lag luam, thiab cov qauv modular, ua tsaug rau lawv cov kev ua haujlwm rwb thaiv tsev siab thiab kev teeb tsa sai. Txawm hais tias cov kws kes duab vajtse thiab cov neeg ua vaj tse suav tias lawv cov kev ua tau zoo tseem ceeb, tus nqi sib txawv ntau raws li ntau yam ntsuas tau.
Vaj Huam Sib Luag Thickness thiab Kev Ua Haujlwm Rwb Thaiv Tsev
Qhov tuab ntawm PU sandwich panel lub plawv ncaj qha cuam tshuam nrog nws tus nqi. Cov tuab txheem yog txij li 40 hli txog 250 hli, nrog cov vaj huam sib luag tuab dua muab kev rwb thaiv cua sov zoo dua (tus nqi U qis dua) tab sis xav tau cov khoom siv raw ntau dua.
Feem ntau lub vaj huam sib luag Puf 100 hli kim dua 20–30% ntau dua li 50 hli sib npaug vim muaj cov polyurethane ua npuas ncauj ntau ntxiv thiab R-tus nqi zoo dua, uas tuaj yeem txo cov cua sov thiab cua txias ntau dhau lub neej ntawm lub tsev.
Kev ua haujlwm zoo ntawm cov khoom siv thermal cuam tshuam rau tus nqi vim tias kev ua tiav cov thermal conductivity qis (kwv yees li 0.022 W/m·K rau PU) xav tau kev tsim cov ua npuas ncauj kom raug thiab kev tswj xyuas zoo.
Cov Khoom Siv Tseem Ceeb thiab Qhov Ceev
Polyurethane nws tus kheej yog tus nqi tseem ceeb uas ua rau muaj kev puas tsuaj. PU ua npuas ncauj lub cev kaw ruaj khov muab kev rwb thaiv tsev zoo heev piv rau lwm txoj hauv kev xws li EPS (expanded polystyrene), tab sis nws cov khoom siv raw - polyols thiab isocyanates - yog cov khoom siv petrochemical nrog cov nqi tsis ruaj khov. Cov ntaub ntawv kev lag luam qhia tau tias cov nqi khoom siv raw suav txog 60–70% ntawm tag nrho cov nuj nqis tsim vaj huam sib luag.
Tsis tas li ntawd xwb, qhov ua npuas ncauj ntom ntom cuam tshuam rau ob qho kev ua tau zoo thiab tus nqi. PU ntom ...
Cov Khoom Siv Rau Kev Sib Tw
Cov vaj huam sib luag sandwich muaj lub hauv paus PU uas sib txuas ntawm ob lub ntsej muag hlau. Cov no tuaj yeem yog cov hlau galvanized, cov hlau pleev xim ua ntej, lossis txhuas. Qee lub tuam txhab tsim khoom loj, zoo li Harbin Dongan Building Sheets Company muab cov vaj huam sib luag puf nrog Al-Mg-Mn ntsej muag vaj huam sib luag, uas tuaj yeem ua rau lub vaj huam sib luag sandwich sib dua, tiv taus xeb dua, thiab muaj zog dua.
Cov hlau galvanized yooj yim yog cov khoom siv pheej yig tshaj plaws thiab muab kev tiv thaiv corrosion txaus, thaum cov hlau ua ntej pleev xim nrog PVDF lossis polyester txheej ntxiv kev ruaj khov thiab kev zoo nkauj. Tau kawg, nws yuav ua rau tus nqi tsim khoom nce ntxiv. Cov hlau txhuas sib dua thiab tiv thaiv corrosion ntau dua tab sis yuav kim dua li hlau.
Qhov tuab ntawm cov tawv hlau kuj tseem ceeb. Feem ntau, qhov tuab ntawm cov tawv hlau yog 0.4-0.6 hli. Dongan Company tuaj yeem muab cov vaj huam sib luag nrog cov tawv hlau tuab ntawm 0.8 hli. Cov tawv tuab dua txhim kho qhov ruaj khov ntawm lub vaj huam sib luag puf thiab kev ua haujlwm thauj khoom, uas kuj txhais tau tias tus nqi siab dua.
Kev Ntsuas Hluav Taws thiab Cov Qauv Kev Nyab Xeeb
Cov vaj huam sib luag Puf txheem feem ntau ua tiav qhov ntsuas hluav taws nruab nrab xws li Euro chav kawm E. Txawm li cas los xij, cov haujlwm, ib yam li cov tsev pej xeem, tsev kawm ntawv, tsev kho mob, xav tau qib kev nyab xeeb siab dua. Cov vaj huam sib luag uas ua tau raws li kev ua haujlwm hluav taws siab xav tau cov qauv tshwj xeeb uas tiv taus hluav taws lossis lwm cov cores, xws li PIR, ua rau muaj kev nyuaj thiab tus nqi ntau ntxiv.
Cov Khoom Siv Rau Kev Tsim Khoom Sandwich Panels
Cov khoom siv tsim khoom muaj feem cuam tshuam loj heev rau qhov zoo ntawm cov sandwich panels. Cov kab ntau lawm siab heev thiab sib xyaw ua ke tuaj yeem ua kom zoo dua qhov ua npuas dej ntawm cov khoom siv polyurethane tseem ceeb thiab kev sib xyaw ua ke ntawm cov hlau phaj ntawm cov khoom siv tseem ceeb.
Kev Kho Kom Zoo thiab Cov Nta Tshwj Xeeb
Cov vaj huam sib luag PU txheem pheej yig dua vim yog kev tsim khoom tsis siv neeg. Cov qhov ntau thiab tsawg tshwj xeeb, cov duab tshwj xeeb, cov ntug profile tshwj xeeb, lossis cov txheej txheem siab heev rau UV, tiv thaiv kev sib sau ua ke, lossis cov qauv tiav ntxiv rau tus nqi.
Piv txwv li, ntxiv rau cov kev cai ib txwm muajcov vaj huam sib luag sandwich, Dongan Lub Tuam Txhab kuj tseem tuaj yeem muab cov vaj huam sib luag sandwich zoo nkauj. Cov neeg siv khoom tuaj yeem xaiv, lossis txawm tias kho kom haum, cov qauv ntawm daim tawv nqaij hlau raws li lawv tus kheej nyiam thiab cov qauv ntawm lub tsev. Kev tsim cov qauv customized txhais tau tias yuav tsum tau ua cov pwm hlau sib cais, thiab tus nqi ntawm cov pwm kuj tseem yuav cuam tshuam rau tus nqi ntawm cov khoom tiav.
