Polyurethane Sandwich vaj huam sib luag tseem hu ua PU vaj huam sib luag thiab polyurethane composite vaj huam sib luag, uas ua raws li lub teb chaws tus qauv GB / T 23932-2009,. Polyurethane Sandwich vaj huam sib luag yog cov khoom siv sib xyaw siv los ua cov txheej txheem thermal rwb thaiv tsev, suav nrog ib txheej hlau, ob txheej hlau thiab txheej tsis yog xim hlau. Nws yog dav siv nyob rau hauv kev tiv thaiv system ntawm logistics warehouse, Hoobkas tsev, ru tsev thiab phab ntsa ntawm lub tsev integrated. Kab lus no feem ntau qhia txog qhov ntsuas hluav taws kub siab ntawm polyurethane sandwich panels.
Kev qhia luv luv ntawm polyurethane sandwich vaj huam sib luag
Polyurethane Sandwich vaj huam sib luag txais yuav cov kab ntau lawm ntawm cov sandwich panels. Sab hauv thiab sab nrauv yog coated nrog txhuas, zinc thiab xim hlau daim hlau, thiab nruab nrab yog coated nrog polyurethane rigid ua npuas ncauj. Thaum kawg, nws yog tsim los ntawm txias thiab solidification. Lub ru tsev vaj huam sib luag nrog anti to leakage sandwich tuaj yeem nqa qhov zoo ntawm polyurethane sandwich vaj huam sib luag mus rau qhov kawg. Piv txwv li, lub thermal rwb thaiv tsev kev ua tau zoo ntawm polyurethane sandwich vaj huam sib luag yog zoo heev vim nws cov thermal conductivity me me, muaj zog thermal rwb thaiv tsev thiab zoo heev hluav taws kub. Tsis tas li ntawd xwb, nws muaj qhov zoo nkauj zoo nkauj thiab yooj yim heev rau nruab. Nws yog non-toxic thiab tasteless, thiab nws yog harmless rau tib neeg beings. Nws yog ib qho ntawm cov kev xaiv thawj zaug rau cov ntaub ntawv vov tsev thiab phab ntsa hauv cov chaw tsim khoom, warehouses thiab lwm qhov chaw uas cov khoom ntim khoom.
Kev ntsuas hluav taws kub thiab kev ua haujlwm ntawm polyurethane sandwich vaj huam sib luag
Kev tiv thaiv hluav taws kub ntawm polyurethane sandwich panels tau mus txog lub teb chaws tus qauv B1, thiab kev tiv thaiv hluav taws zoo heev. Vim li cas? Cov laj thawj yog raws li nram no:
(1) Lub thermal conductivity ntawm polyurethane yog qhov tsawg. Thaum qhov ntom ntom ntawm polyurethane yog 35-40kg / m3, thermal conductivity ntawm polyurethane tsuas yog 0.018-0.024/(mk), uas yog qis tshaj ntawm cov ntaub ntawv rwb thaiv tsev uas tau tsim nyob rau tam sim no, tsuas yog ib nrab ntawm EPS. Tsis tas li ntawd, polyurethane muaj cov dej tsis zoo thiab dej tsis zoo. Polyurethane yog cov khoom siv hydrophobic nrog kaw porosity ntau dua 90 feem pua. Yog li ntawd, polyurethane yuav tsis nce lub thermal conductivity vim dej nqus, thiab phab ntsa yuav tsis xau;
(2) Polyurethane yog cov khoom siv tua tus kheej, uas nyuaj rau hlawv tom qab ntxiv cov nplaim hluav taws. Polyurethane yuav decompose tsuas yog nyob rau hauv kub kub, thiab nws softening point yog siab tshaj 250 degree;
(3) Thaum kub hnyiab, polyurethane yuav tsim cov pa roj carbon monoxide, uas yuav khaws cia rau ntawm nws lub ntsej muag ua npuas ncauj, pab cais cov pa oxygen ntawm lub hauv paus ua npuas ncauj thiab tiv thaiv kev sib kis ntawm hluav taws. Tsis tas li ntawd, polyurethane yuav tsis tsim cov pa phem ntawm qhov kub thiab txias, uas tsis muaj teeb meem rau tib neeg kev noj qab haus huv;
(4) Vim hais tias polyurethane muaj kev tiv thaiv hluav taws zoo heev, nws tuaj yeem txo qhov tuab ntawm phab ntsa, yog li ua rau thaj chaw muaj nyob hauv tsev;
(5) Lub porosity thiab cov qauv ntawm polyurethane yog qhov ruaj khov, tsis yooj yim rau tawg, thiab nws muaj kev ruaj ntseg zoo. Nws lub neej kev pab cuam kuj siab dua li ntawm lwm cov ntaub ntawv thermal rwb thaiv tsev, thiab nws cov nqi kev ua tau zoo kuj yog siab.
