1. Polyurethane board rigid foam polyurethane muaj lub zog txuag zoo tshaj plaws, nws cov nqi thermal conductivity tsuas yog 0.017 ~ 0.025w/k·m, yog qhov tsawg kawg nkaus tus nqi ntawm tag nrho cov thermal rwb thaiv tsev cov ntaub ntawv ( roj hmab hmoov polystyrene khoom thermal rwb thaiv tsev mortar 0 0}6 ~ 0 08w/k·m, inorganic teeb aggregate thermal rwb thaiv tsev mortar 0 0}7 ~ 0.10w/k·m, Moulded polystyrene ua npuas ncauj board EPS 0.04 ~ 0.045w/k·m, extruded polystyrene ua npuas ncauj board XPS 0.031 ~ 0.035w/k·m ), yog li ntawd, nyob rau hauv lub premise ntawm tib lub zog txuag Performance index, rwb thaiv tsev txheej thickness yog qhov thinest, lub rwb thaiv tsev sab nraud tom qab tsim qhov system kev ruaj ntseg Performance index yog qhov zoo tshaj plaws.
2. Nyuaj ua npuas ncauj polyurethane yog cov qauv ua npuas zoo tshaj plaws, nrog cov qauv zoo dua qub thiab lub cev thiab tshuaj lom neeg ntawm polyurethane phaj. Vim hais tias nyuaj ua npuas ncauj polyurethane yog ob lub ntsiab ua kua crosslinked ua npuas ncauj, lub cev ua npuas ncauj yog thermosetting mesh qauv, siab kaw ntawm tes tus nqi, siab compressive thiab tensile zog, thiab zoo kub stability thiab kev nyab xeeb siv kub ntawm 120 degree. Txawm li cas los xij, EPX thiab XPS yog thermoplastic ua npuas ncauj nrog granular thiab linear qauv, siab thermal rhiab heev, tsis zoo thermal stability thiab kub tsis kam ntawm tsuas yog 70 degree, thiab muaj kev pheej hmoo ntawm theem nrab foaming ntim deformation thaum siv nyob rau hauv qhov kub thiab txias. Yog li ntawd, qhov tawg zais qhov phom sij tshwm sim los ntawm kev deformation ntawm lub rwb thaiv tsev ntawm lub rwb thaiv tsev sab nraud ntawm polyurethane rwb thaiv tsev board yog tsawg, thiab xoob tawg ntawm cov nplaum polystyrene particle rwb thaiv tsev mortar thiab qhuav shrinkage tawg ntawm inorganic rwb thaiv tsev mortar xws li kaw perlite thiab iav npuas tau raug zam kom zoo.
3. Polyurethane ua npuas ncauj yog waterproof tab sis tsis hydrophobic, thiab muaj ib tug npaum li cas ntawm -OH pab pawg neeg ntawm qhov kawg ntawm nws molecular saw. Nws muaj kev sib raug zoo nrog cov ntaub ntawv cement-based thiab yooj yim rau pasted nrog nplaum mortar. Txawm li cas los xij, EPS thiab XPS boards yog cov khoom siv hydrophobic, uas nyuaj rau fuse nrog cov khoom siv cement. Thaum pasting nrog nplaum mortar thiab plastering mortar, polyurethane boards yog ib qho yooj yim heev los ua cuav adhesion thiab disadhesion. Yog li ntawd, sab nrauv rwb thaiv tsev ntawm polyurethane rwb thaiv tsev board muaj qhov tsawg tshaj plaws zais txaus ntshai ntawm ntog tawm.
4. Polyurethane rwb thaiv tsev board sab nrauv rwb thaiv tsev muaj qhov zoo tshaj plaws hluav taws kub kev nyab xeeb. Vim tias polyurethane ua npuas ncauj yog cov khoom siv thermosetting, nws tsim cov txheej txheem carbon tom qab hluav taws kub. Nrog rau qhov thickening ntawm cov pa roj carbon monoxide txheej, cov cua sov thiab cov pa oxygen hloov tau raug cais tawm, thiab thaum kawg ib txheej uas tsis yog-combustible los yog tsis-combustible txheej yog tsim los tiv thaiv cov nplaim hluav taws. Thiab EPS, XPS lub rooj tsavxwm rau cov khoom siv thermoplastic, hluav taws kub nyhiab melting, tsis tuaj yeem tsim cov carbonized barrier nrog cov evaporation ntawm nplaim taws, melting kua rau hauv cov hluav taws kub, qhov hluav taws kub ceev ceev, yooj yim tsim flameout, yog li polyurethane rwb thaiv tsev board rau ua sab nrauv phab ntsa rwb thaiv tsev engineering yog qhov ruaj ntseg tshaj plaws, tsis txhob txhawj txog hluav taws kub.
5. Cov khoom siv polyurethane muaj kev tiv thaiv corrosion thiab kev laus, qhov ruaj khov ntawm lub cev thiab tshuaj lom neeg, thiab lub neej ua haujlwm ntev tshaj li cov khoom siv hluav taws xob zoo tib yam. Yog li ntawd, qhov zoo tshaj plaws nqi kev ua tau zoo.
