Polyurethane rigid foam hajoale e amoheloa lefatšeng ka bophara e le thepa e ntle ka ho fetisisa ea moaho.E na le conductivity e tlase ea mocheso, e hanyetsa moroalo o motle, matla a holimo a ho kobeha, ha e monye metsi, ha e bola, ha e lome likhoto tse jeoang ke likokoanyana, ho lieha ho hoholo ha lelakabe le mefuta e mengata ea ho hanyetsa mocheso.

Khomphuta e sebelisetsoa ho laola mohala oa tlhahiso o ikemetseng ka ho feletseng, e le hore mocheso o phahameng oa mocheso oa polyurethane le poleiti ea tšepe e koahetsoeng ka mebala e thehoa ka ho feletseng 'me e kopantsoe ka thata.Litšepe tsa 'mala o thata le lisebelisoa tse bonolo tsa lik'hemik'hale li kopantsoe le mochini o etsang foam oa polyurethane PU ho theha moaho oa morao-rao oa ts'ireletso ea tikoloho ea mahlale le theknoloji ea polyurethane (PU), e leng toro ea meralo ea meralo, baqapi le baenjiniere.

1. Polyurethane e thata e na le lintho tse thibelang mongobo le tse sa keneleng metsi.Sekhahla se koalehileng sa polyurethane se thata se ka holimo ho 90%, e leng thepa ea hydrophobic 'me e ke ke ea eketsa mocheso oa mocheso ka lebaka la ho kenngoa ha mongobo,' me bokaholimo ba lerako bo ke ke ba phalla metsi.

2. Quality polyurethane e na le conductivity e tlaase ea mocheso le ts'ebetso e ntle ea mocheso.Ha boima ba polyurethane e thata e le 38 ~ 42kg/m3, mocheso oa mocheso ke 0.018 ~ 0.024w/(mk), e leng hoo e ka bang halofo ea EPS, 'me ke eona e tlaase ka ho fetisisa har'a lisebelisoa tsohle tsa ho pata mocheso hona joale.

3. Hobane poleiti ea sandwich ea polyurethane e na le ts'ebetso e babatsehang ea mocheso oa mocheso, tlas'a litlhoko tse tšoanang tsa ho boloka mocheso, e ka fokotsa botenya ba mohaho oa enfelopo ea mohaho, kahoo e eketsa sebaka sa tšebeliso ea ka hare.

4. Ts'ebetso e tlase e akaretsang ea litšenyehelo.Leha theko ea yuniti ea foam e thata ea polyurethane e phahame ho feta ea lisebelisoa tse ling tsa setso tsa ho kenya letsoho, litšenyehelo tse ntseng li eketseha li tla fokotsoa ke phokotso e kholo ea litšenyehelo tsa ho futhumatsa le ho pholisa.
