Ua ib yam khoom siv rwb thaiv tsev uas txuag hluav taws xob, polyurethane sandwich panel tau dhau los ua ib qho tseem ceeb ntawm cov chaw tsim khoom lag luam niaj hnub, cov chaw khaws khoom logistics, thiab cov chaw cia khoom txias. Hom vaj huam sib luag tsev no, uas muab cov txheej hlau nto nrog cov khoom siv polyurethane, xav tias yuav tseem ceeb zuj zus yav tom ntej.
Kev Ua Tau Zoo heev
Qhov zoo tshaj plaws ntawm polyurethane sandwich vaj huam sib luag yog lawv qhov kev ua tau zoo ntawm kev rwb thaiv tsev kub. Cov ntaub ntawv ua npuas ncauj polyurethane muaj cov khoom rwb thaiv tsev kub zoo, nrog rau kev ua kom sov tsawg li 0.017-0.025 W / (m · K). Qhov no txhais tau tias lub vaj huam sib luag tsuas yog 5 centimeters tuab tuaj yeem ua tiav cov txiaj ntsig rwb thaiv tsev zoo ib yam li phab ntsa pob zeb ib-meter tuab. Ua tsaug rau nws qhov kev ua tau zoo ntawm kev rwb thaiv tsev zoo heev, polyurethane sandwich vaj huam sib luag tau dhau los ua cov khoom siv nyiam rau kev tsim cov chaw cia khoom txias.
Cov vaj huam sib luag polyurethane sandwich no tiv thaiv dej tsis nkag, tiv thaiv dej noo, thiab ruaj khov heev. Lub polyurethane ua npuas ncauj kaw tau 95%, ua rau cov dej noo tsis nkag mus tau zoo. Lub polyurethane sandwich panels nqus dej tsawg dua 3%. Tib lub sijhawm, thaum kub txog 30°C, qhov loj ntawm cov vaj huam sib luag yuav tsawg dua 1%, ua kom siv tau ntev yam tsis muaj kev hloov pauv.
Qhov kev tiv thaiv hluav taws ntawm cov vaj huam sib luag polyurethane sandwich tuaj yeem ncav cuag Chav Kawm B1. Cov vaj huam sib luag polyurethane sandwich yog cov hluav taws kub, tab sis lawv tsis hlawv tsuas yog 3 vib nas this tom qab raug tshem tawm ntawm nplaim taws. Txawm hais tias qis dua me ntsis rau cov vaj huam sib luag sandwich pob zeb hauv qhov no, lawv tseem ua tau raws li cov kev cai nyab xeeb hluav taws yooj yim.
Raws li kev tsim kho, ua tsaug rau ob txheej hlau vaj huam sib luag rau sab saum toj thiab hauv qab, polyurethane sandwich panels muaj lub zog zoo. Lub zog compressive ntawm polyurethane sandwich panels yog ntau dua 150 kPa. Txawm li cas los xij, cov khoom siv tseem ceeb yog polyurethane ua npuas ncauj, uas ua rau cov vaj huam sib luag sib dua 30-60% dua li cov khoom ib txwm muaj. Qhov no ua rau polyurethane sandwich panels yog cov khoom siv nyiam rau kev tsim kho sib dua.
Kev Xav Tau Ntau Lawm
Tam sim no, cov txheej txheem tsim cov polyurethane sandwich panels yog ua haujlwm tsis siv neeg heev. Cov chaw tsim khoom loj, xws li Harbin Dong'an Building Sheets Co., Ltd., siv cov kab ntau lawm tas mus li los koom ua ke tag nrho cov txheej txheem ntawm kev ua npuas dej, kho, thiab ua cov panels.
Kev ua npuas dej siab thiab kev tsim khoom yog ib kauj ruam tseem ceeb hauv kev tsim cov vaj huam sib luag polyurethane sandwich. Qhov zoo ntawm kev ua npuas dej ncaj qha txiav txim siab qhov ua tau zoo ntawm cov vaj huam sib luag. Thaum lub sijhawm tsim khoom, cov chaw tsim khoom yuav tsum tswj hwm qhov kub ntawm cov saw hlau thiab cov ntaub ntawv ua npuas dej kom raug. Qhov ceev ntawm cov kab ntau lawm kuj tseem ceeb heev, vim nws cuam tshuam rau qhov sib xws ntawm cov txheej txheem ua npuas dej tseem ceeb.
