Inov Polyurethane Phthalic Anhydride Polyester Polyol Yogwiritsidwa Ntchito Muzophatikiza Zathovu Zolimba
Mndandanda wa Foam Wokhazikika
MAU OYAMBA
Mndandanda wa ma polyols makamaka amachokera ku zipangizo monga phthalic anhydride ndi diethylene glycol.Amagwiritsidwa ntchito kwambiri m'munda wa thovu lolimba komanso angagwiritsidwenso ntchito m'munda wa zomatira.Ili ndi ubwino wa fungo lochepa, chroma yochepa, reactivity yapamwamba, kukana kwa hydrolysis, kununkhira kwakukulu, kukhazikika kwapangidwe ndi madzi abwino.Mapangidwe azinthu amatha kusinthidwa malinga ndi zomwe makasitomala amafuna.
APPLICATION
Mndandanda wa polyester polyols ukhoza kugwiritsidwa ntchito kwambiri mu dongosolo la thovu lolimba monga firiji, kusungirako kuzizira, kupopera mbewu mankhwalawa, mphamvu ya dzuwa, mapaipi otentha, kutchinjiriza nyumba, etc., ndipo ena ndi oyenera zomatira.
