Polyurethane Sandwich board muaj kev siv tsis tau hauv peb lub neej txhua hnub, yog li nws yog dab tsi?
Nta:
1. Nyuaj polyurethane muaj thermal conductivity tsawg thiab thermal ua haujlwm zoo; Thaum cov tuab ntom ntu ntawm rigid polyurethane yog 35 ~ 4 {}}}}}}. ), yog tam sim no thermal conductivity ntawm tag nrho cov thermal rwb thaiv tsev ntaub ntawv yog tsawg heev.
2. tawv polyurethane muaj noo noo-pov thawj, waterproof kev ua tau zoo; Hard polyurethane muaj qhov porosity kaw ntau dua 95 feem pua, uas yog cov khoom siv hydrophobic. Nws yuav tsis nce thermal conductivity vim yog nqus noo noo, thiab phab ntsa yuav tsis pom dej.
3. tawv polyurethane hluav taws kub, nplaim retardant, kub tsis kam; Tom qab qhov sib ntxiv ntawm cov nplaim hluav taws kub, polyurethane yog ib yam khoom ntawm cov khoom siv hluav taws xob refractory nws tus kheej, nws qhov muag muag tuaj yeem ncav cuag ntau tshaj 250 degrees Celsius, thiab nws yuav decompose tsuas yog nyob rau ntawm qhov kub siab dua: ntxiv rau, polyurethane yuav tsim ib txheej carbonization ntawm qhov chaw. ntawm nws cov npuas dej thaum nws hlawv, uas pab cais cov npuas dej hauv qab no thiab tuaj yeem tiv thaiv kev sib kis ntawm hluav taws. Ntxiv mus, polyurethane tsis tsim cov pa phem ntawm qhov kub thiab txias.
4. vim tias cov ntawv polyurethane muaj kev ua haujlwm zoo ntawm cov rwb thaiv tsev kub; Nyob rau hauv tib lub thermal rwb thaiv tsev yuav tsum, lub thickness ntawm cov txheej txheem tiv thaiv ntawm lub tsev yuav raug txo, yog li ua rau lub sab hauv tsev siv cheeb tsam.
5. muaj zog deformation kuj; Tsis yooj yim rau tawg, ua tiav ruaj khov thiab nyab xeeb.
6. Cov qauv porosity ntawm cov khoom siv polyurethane ruaj khov; Yeej kaw cov qauv ntawm tes, tsis yog tsuas yog kev ua haujlwm zoo thermal rwb thaiv tsev, tab sis kuj khov-thaw kuj, suab nqus. Qhov nruab nrab ntawm lub neej ntawm cov ntaub nplaum nplaum polyurethane rwb thaiv tsev tuaj yeem ncav cuag ntau tshaj 30 xyoo nyob rau hauv cov xwm txheej ntawm kev siv thiab kev saib xyuas. Nws tuaj yeem ua tiav hauv lub neej ntawm cov qauv hauv kev pabcuam ib txwm muaj, qhuav, ntub dej lossis electrochemical corrosion, nrog rau cov kab, fungi lossis algae loj hlob lossis kev puas tsuaj los ntawm nas thiab lwm yam ua rau sab nraud, yuav tsis raug puas tsuaj.
7. Kev ua tau zoo ntawm tus nqi; Txawm hais tias chav tsev tus nqi ntawm polyurethane ua npuas ncauj yog siab dua li ntawm lwm cov ntaub ntawv rwb thaiv tsev, tus nqi nce ntxiv yuav raug them los ntawm kev txo nqi cua sov thiab cua txias.
