Foam yolimba ya polyurethane pakadali pano imadziwika padziko lonse lapansi ngati zida zabwino kwambiri zomangira.Imakhala ndi matenthedwe otsika, kukana katundu wabwino, mphamvu yopindika kwambiri, osayamwa madzi, osawola, osalumidwa ndi makoswe omwe amadya ndi tizilombo, kuchedwa bwino kwa lawi komanso kukana kutentha kwakukulu.
Kompyutayo imagwiritsidwa ntchito poyang'anira mzere wopangira makina, kotero kuti polyurethane yotentha kwambiri yomwe imatulutsa thovu ndi mbale yachitsulo yokhala ndi utoto imapangidwa mokhazikika ndikuphatikizidwa mwamphamvu.Chitsulo chosasunthika komanso zinthu zofewa zopangira mankhwala zimaphatikizidwa ndi makina opangira thovu a polyurethane PU kuti apange gulu laposachedwa lasayansi komanso laukadaulo loteteza zachilengedwe - polyurethane (PU) sangweji yamtundu wachitsulo, lomwe ndi loto la omanga, okonza mapulani ndi mainjiniya.
1. Polyurethane yolimba imakhala ndi mphamvu zoteteza chinyezi komanso madzi.Maselo otsekedwa a polyurethane okhwima ali pamwamba pa 90%, omwe ndi zinthu za hydrophobic ndipo sangawonjezere kutentha kwa matenthedwe chifukwa cha kuyamwa kwa chinyezi, ndipo pamwamba pa khoma silingalowe madzi.
2. Ubwino wa polyurethane uli ndi kutsika kwamafuta otsika komanso magwiridwe antchito abwino.Pamene kachulukidwe ka polyurethane yolimba ndi 38 ~ 42kg/m3, kutentha kwa matenthedwe kumakhala 0.018 ~ 0.024w/(mk), yomwe ili pafupi theka la EPS, ndipo ndiyotsika kwambiri pakati pa zipangizo zonse zotenthetsera pakali pano.
3. Chifukwa mbale ya sangweji ya polyurethane imakhala ndi ntchito yabwino yotchinjiriza kutentha, pansi pa zofunikira zotetezera kutentha, imatha kuchepetsa makulidwe a envelopu yomanga, potero ikuwonjezera malo ogwiritsira ntchito m'nyumba.
4. Ntchito yotsika mtengo yotsika mtengo.Ngakhale mtengo wamtundu wa polyurethane thovu wokhazikika ndi wokwera kuposa wa zida zina zotchinjiriza zachikhalidwe, mtengo wokwerawo udzachepetsedwa ndi kutsika kwakukulu kwamitengo yotenthetsera ndi kuziziritsa.
