Sekhahla sa lisele tse koetsoeng tsa motheo oa foam ea polyurethane se feta 95%, e leng se thibelang ho kenella ha mongobo ka katleho. Sekhahla sa ho monya metsi sa liphanele tsa sandwich tsa polyurethane se ka tlase ho 3%. Ka nako e ts'oanang, tlas'a liphetoho tsa mocheso oa 30°C, phetoho ea boholo ba liphanele e ka tlase ho 1%, e leng se netefatsang tšebeliso ea nako e telele ntle le ho fetoha.

Ho hanyetsa mollo ha diphanele tsa sandwich tsa polyurethane ho ka fihla ho Sehlopha sa B1. Diphanele tsa sandwich tsa polyurethane di a tuka, empa di emisa ho tuka metsotswana e 3 feela kamora ho tloswa lelakabeng. Le hoja di le tlase hanyane ho feta diphanele tsa sandwich tsa boya ba lefika ntlheng ena, di ntse di fihlela ditlhoko tsa motheo tsa polokeho ya mollo.

Ka sebopeho, ka lebaka la mekhahlelo e 'meli ea liphanele tsa tšepe holimo le tlase, liphanele tsa sandwich tsa polyurethane li na le matla a matle a sebopeho. Matla a khatello a liphanele tsa sandwich tsa polyurethane a feta 150 kPa. Leha ho le joalo, thepa ea mantlha ke foam ea polyurethane, e leng se etsang hore liphanele li be bobebe ka 30-60% ho feta lihlahisoa tsa setso. Sena se etsa hore liphanele tsa sandwich tsa polyurethane e be thepa e ratoang bakeng sa kaho e bobebe.

Tlhoko e Phahameng ea Tlhahiso
Hona jwale, tshebetso ya tlhahiso ya diphanele tsa sandwich tsa polyurethane e etswa ka boiketsetso haholo. Bahlahisi ba ka sehloohong, jwalo ka Harbin Dong'an Building Sheets Co., Ltd., ba sebedisa mela e tswelang pele ya tlhahiso ho kopanya tshebetso yohle ya ho fofonela, ho lokisa le ho bopa diphanele.

Ho etsa foam ka kgatello e phahameng le ho e bopa ke kgato ya bohlokwa tlhahisong ya diphanele tsa sandwich tsa polyurethane. Boleng ba foam bo laola ka ho toba tshebetso ya diphanele. Nakong ya tlhahiso, bahlahisi ba hloka ho laola mocheso wa boto ya ketane le thepa ya foam ka nepo. Lebelo la mohala wa tlhahiso le lona le bohlokwa, kaha le ama ho tshwana ha tshebetso ya foam ya mantlha.
