Polyurethane insulation boardzinthu zimenezi mu ndondomeko yeniyeni kupanga adzakhala ndi zosiyanasiyana ntchito zosiyanasiyana kutchinjiriza, ndi nkhani imeneyi kupanga nthawi, tiyenera kumvetsa kwambiri ndondomeko yawo, pambuyo pa zonse, kumvetsa ndondomeko, kutithandiza bwino kusankha zinthu.

Posankha zipangizo zotetezera polyurethane, ndondomeko yonseyi imagawidwa m'magulu atatu osiyanasiyana kuchokera mkati kupita kunja.Kawirikawiri, pamene iwo ali m'gulu, iwo onse amayenera kudutsa mndandanda wa mankhwala ochotsa dzimbiri, ndipo njira zonse zimakhala zabwino, pokonzekera, kuti zitsimikizire kuti zingathe kufika pamtundu wina, roughness pamwamba, ikhoza kukhala. kukulitsidwa mpaka ma microns 12.5, omwe Awa ndi gawo loyamba la kapangidwe kake, gawo loyamba la kapangidwe kameneka ndikuteteza madzi.

Chigawo chachiwiri ndi chotchinga, chomwe chimagwiritsidwa ntchito polumikizana pakati pa chitoliro chonse ndi kunja, koma chimadzaza ndi madzi enaake a thovu, omwe amakonzedwa motere ndipo amagwiritsidwa ntchito kuti asungunuke.

Zigawo zitatu za mapepala otsekemera a polyurethane amakonzedwa ndikusankhidwa m'njira zosiyanasiyana, nthawi zambiri ndi pulasitiki yotchinga ndi chitetezo chotetezera, chomwe chimakonzedwa m'njira zosiyanasiyana kuti chiteteze ku zinthu zolimba.

Panthawi imodzimodziyo, mapepala otsekemera a polyurethane awa amapezeka muzinthu zosiyanasiyana muzochitika zenizeni, ndipo ntchito yawo ndi yabwino.
