WLub kaus mom puas yog nruj polyurethane ua npuas?
Rigid Polyurethane ua npuas dej, tseem hu ua polyurethane rigid ua npuas ncauj lossis ua npuas ncauj, muaj cov yam ntxwv hauv qab no:
· Cia li muaj cov nyhuv insulation zoo
· Zoo lub teeb yuag
· Zoo lub zog
④ Cov tshuaj zoo tshuaj tiv thaiv
· Rwb thaiv tsev zoo
Qhov tseem ceeb tshaj plaws ntawm pu rigid foam yog tias nws cov thermal rwb thaiv tsev cov ntaub ntawv (thiab lwm yam hluavtaws thermal cob cov khoom siv hluav taws xob resin rwb thaiv tsev cov khoom siv. Ntawm cov polyurethane khoom, cov nyiaj ntawm polyurethane rigid ua npuas ncauj yog thib ob nkaus xwb rau polyurethane mos ua npuas.
Raws li cov khoom siv sib txawv, cov khoom siv ua npuas dej nrog cov qauv sib txawv thiab cov nplaim hluav taws xob thiab hloov kho cov khoom siv raw ua si. Qhov no tso cai rau lub ntom ntom ntawm cov huab cua nruj heev kom haum rau ntau yam, txij li qis li 1000kg / m3 ntawm yuav luag lub cev.
Taw qhia rau siv cov roj av tsawg polyurethane rigid ua npuas yog tsuas yog siv rau thermal rwb thaiv tsev. Feem ntau polyurethane rigid foams muaj qhov ntom ntawm 28 ~ 50kg / m3. Lawv feem ntau yog siv rau thermal rwb thaiv tsev, xws li rwb thaiv tsev puv cov tsev tub yees thiab cov pa roj hmab, rwb thaiv tsev ntawm cov khoom txias thiab cov tsheb txias, thiab lwm yam.
High-ceev polyurethane rigid ua npuas ncauj thiab khob fiber ntau siv cov npuas muaj zog muaj lub zog siab thiab tuaj yeem siv los ua cov khoom ntoo. Nws cov yam ntxwv yog tias qhov ceev me me dua li ntawm cov ntoo, cov ntawv tsim kho cov txheej txheem, thiab cov nkoj ntoo ntoo, piv txwv li cov khoom.
Ultra-Tsawg Qis Rigid Ua Npuas Ncauj yog feem ntau siv raws li ntim khoom, thiab lwm yam.
Polyurethane Rigid Ua Npuas Ncauj tsis yog deform tseem nyob hauv qab qee yam thauj khoom, tab sis yuav tawg thaum lub thauj khoom nce ntxiv, thiab deformation tsis tuaj yeem rov qab los. Thiab feem ntau cov khoom lag luam nruj heev yog kaw-cell ua npuas cov qauv, uas tau txawv ntawm cov mos foams.
