XPS insulation Board wani tsayayyen katakon filastik ne mai kumfa mai kumfa wanda aka yi da resin polystyrene azaman albarkatun ƙasa da sauran albarkatun ƙasa da polymers, mai zafi da gauraye da allura tare da mai kara kuzari a lokaci guda, sannan an fitar da shi da gyare-gyare.Sunan kimiyya shine extruded polystyrene foam (XPS) don rufin zafi.XPS yana da ingantaccen tsarin rufaffiyar sawun zuma, wanda ke ba hukumar XPS damar samun ƙarancin sha ruwa (kusan babu shayar ruwa) da ƙarancin wutar lantarki., High matsawa juriya, anti-tsufa (kusan babu tsufa bazuwar sabon abu a cikin al'ada amfani) The XPS jirgin yana da m surface Layer da rufaffiyar-cell tsarin ciki Layer.Its thermal conductivity yana da ƙasa da EPS na kauri ɗaya, don haka yana da mafi kyawun aikin rufin zafi fiye da EPS.

Don bangon waje na ginin guda ɗaya, kauri na allon xps na iya zama ƙasa da sauran nau'ikan kayan rufewa;saboda tsarin rufaffiyar sel na ciki.Sabili da haka, yana da juriya mai kyau na danshi, kuma har yanzu yana iya kula da kyakkyawan aikin rufewar thermal a cikin yanayi mai laushi;ya dace da gine-ginen da ke da buƙatu na musamman don ƙaddamar da zafin jiki kamar ajiyar sanyi, kuma ana iya amfani dashi don gine-gine tare da tubali ko bango na waje na dutse da ke fuskantar kayan.

Jirgin polyurethane mai ƙarfi yana da ƙarancin ƙarancin thermal da kyakkyawan aikin thermal.Lokacin da babban yawa na m polyurethane ne 35 ~ 40kg/m3, thermal conductivity ne kawai 0.018g ~ 0.023w / (m · k), wanda shi ne game da rabin EPS, wanda shi ne mafi ƙasƙanci thermal watsin na duk rufi kayan.Jirgin polyurethane mai ƙarfi yana da tabbacin danshi kuma mai hana ruwa.Rufaffiyar tantanin halitta mai ƙarfi na polyurethane mai ƙarfi yana sama da 90%, wanda shine abu na hydrophobic, wanda ba zai ƙara haɓakar thermal ba saboda shayarwar danshi, kuma bangon ba zai sami ruwa ba.

Idan aka kwatanta da sauran kayan rufewa, kumfa mai ƙarfi na polyurethane yana da mafi kyawun aikin rufewar thermal.Sabili da haka, ƙananan sandwich na polyurethane na bakin ciki na iya saduwa da ƙa'idodin da suka dace game da iyakokin amfani da makamashi, wanda ke ba da damar yin amfani da ƙananan ƙananan ƙananan lokacin ginawa, ceton sararin samaniya;barga ingancin da high samar yadda ya dace.A cikin yanayin haɓakar haɓakar buƙatu, layin samar da masana'anta na bangarori na sandwich na polyurethane ba kawai sauƙaƙe kulawar inganci ba, har ma yana kawo tattalin arziki mai kyau da gasa.
