Polyurethane Sandwich vaj huam sib luag txais cov xim zoo xim coated steel ntawv raws li txheej txheej.Thiab cov tub ntxhais yog ua los ntawm polyurethane, uas yog foamed thiab kho thaum kub kub, thiab yog tsim los ntawm ob-txoj kev tswj molding.Nws muaj zoo thermal rwb thaiv tsev kev ua tau zoo thiab zoo tagnrho khoov, suab rwb thaiv tsev thiab hluav taws tsis kam.Piv nrog rau lwm cov vaj huam sib luag, tsawg dua thickness yog xav tau yog tias xav kom ua tiav tib lub hom phiaj, thiab qhov chaw ntawm lub tsev yog nce.
1.Fireproof kev ua tau zoo: Polyurethane yog B2 qib fireproof khoom nrog cov pa ntsuas ≥28, uas tuaj yeem txo qhov hluav taws kub.
2.Insulation kev ua tau zoo: Lub thermal conductivity ntawm polyurethane yog 0.019-0.023w / mk, uas yog ib qho zoo heev thermal rwb thaiv tsev khoom.
3.Zoo suab rwb thaiv tsev: zoo suab rwb thaiv tsev, zoo txo qhov cuam tshuam ntawm sab nraud suab nrov.
4.Qhov hydrophobicity ntawm polyurethane yog ≤ 0.5%, thiab muaj cua nruj zoo.
5.Bulk ceev yog hais txog 42kg / m³, siab zog, ruaj khov ntev.
