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 osiyana kuchokera mkati kupita kunja.Kawirikawiri, pamene iwo ali m'gulu, iwo onse ayenera kudutsa mndandanda wa mankhwala kuchotsa dzimbiri, ndipo njira zonse ndi zabwino, pokonza processing, kuonetsetsa kuti akhoza kufika muyezo winawake, pamwamba roughness, akhoza 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 chosanjikiza, chomwe chimagwiritsidwa ntchito polumikizana pakati pa chitoliro chonse ndi kunja, komanso chimadzazidwa ndi madzi ena a thovu, omwe amakonzedwa motere ndipo amagwiritsidwa ntchito popanga.

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.
