XPS Insulation board ndi bolodi la pulasitiki lolimba lopangidwa ndi thovu lopangidwa ndi utomoni wa polystyrene monga zopangira kuphatikiza zinthu zina zopangira ndi ma polima, zotenthetsera ndi kusakaniza ndi kubayidwa ndi chothandizira nthawi yomweyo, kenako zimatuluka ndikuwumbidwa.Dzina lake lasayansi ndi extruded polystyrene foam (XPS) pofuna kutchinjiriza kutentha.XPS ili ndi mawonekedwe otsekeka a uchi, omwe amalola bolodi la XPS kukhala ndi madzi otsika kwambiri (pafupifupi mayamwidwe amadzi) komanso kutsika kwamafuta., Kukaniza kwakukulu, kutsutsa kukalamba (pafupifupi palibe vuto la kuwonongeka kwa ukalamba mu ntchito yachibadwa) .Bodi la XPS liri ndi malo osakanikirana ndi mawonekedwe otsekedwa a mkati.Kutentha kwake ndikotsika kwambiri kuposa EPS ya makulidwe omwewo, kotero kumakhala ndi magwiridwe antchito abwinoko kuposa EPS.

Kwa khoma lomwelo lakunja kwa nyumba, makulidwe a xps board amatha kukhala ang'onoang'ono kuposa mitundu ina ya zida zotchinjiriza;chifukwa cha kutsekedwa-maselo dongosolo la mkati wosanjikiza.Chifukwa chake, imakhala ndi kukana bwino kwa chinyezi, ndipo imatha kukhalabe ndi ntchito yabwino yotchinjiriza kutentha m'malo achinyezi;ndi yoyenera kwa nyumba zomwe zili ndi zofunikira zapadera zotetezera kutentha monga kusungirako kuzizira, komanso zingagwiritsidwe ntchito pomanga nyumba zokhala ndi njerwa kapena miyala yakunja yoyang'ana khoma.

Gulu lolimba la polyurethane limakhala ndi matenthedwe otsika komanso magwiridwe antchito abwino.Pamene kachulukidwe wochuluka wa polyurethane olimba ndi 35 ~ 40kg/m3, matenthedwe conductivity ndi 0.018g - 0.023w/(m·k), amene ali pafupifupi theka la EPS, amene ndi otsika matenthedwe madutsidwe zipangizo zonse kutchinjiriza.Gulu lolimba la polyurethane ndilopanda chinyezi komanso madzi.Maselo otsekedwa a polyurethane okhwima ali pamwamba pa 90%, omwe ndi zinthu za hydrophobic, zomwe sizidzawonjezera kutentha kwa matenthedwe chifukwa cha kuyamwa kwa chinyontho, ndipo khoma silidzataya madzi.

Poyerekeza ndi zida zina zotchingira, thovu lolimba la polyurethane lili ndi ntchito yabwino kwambiri yotchinjiriza.Chifukwa chake, mapanelo ocheperako a sangweji a polyurethane amatha kukwaniritsa malamulo ofunikira pakumanga malire ogwiritsira ntchito mphamvu, zomwe zimalola kugwiritsa ntchito mapanelo owonda pakumanga, kupulumutsa malo omanga;khola khalidwe ndi mkulu kupanga bwino.Pankhani ya kuwonjezeka kwakukulu kwa kufunikira, mzere wopangira fakitale wa mapanelo a masangweji a polyurethane sikuti umangowongolera kuwongolera, komanso umabweretsa chuma chabwino komanso mpikisano.
