Alkyl Polyether: Atike Siwo Wozãna Le Taɖodzinu Geɖewo Me Na Dɔwɔwɔ Vovovowo
Dɔwɔwɔ ƒe Agble Gãwo
Le atikewɔƒewo la, wozãa alkyl polyethers abe nusiwo wotsɔ wɔa polyurethane foamwo, nusiwo wotsɔna léa nu ɖe nu ŋu, nusiwo wotsɔ xea mɔ na nu, kple elastomerwo ene. Wozãa polyurethane foam geɖe le xɔmenuwo, mattress, ʋuwo ƒe zikpuiwo, kple xɔtunuwo me. Wozãa polyurethane-nulénu kple nutrenu tsɔ ƒoa xɔwo, ʋuwo, kple elektrɔnikmɔ̃wo nu ƒu.
Le atikewɔƒewo la, alkyl polyethers nyea kpeɖeŋutɔ kple nusiwo naa atikewo ƒe ʋeʋẽ lilili le atikewo me, si wɔnɛ be woƒe liƒo kple woƒe ʋeʋẽ nyona ɖe edzi. Wozãa wo hã tsɔ wɔa futukpɔnuwo, nusiwo naa fuɖenamenuwo, kple nusiwo naa tsi nɔa lãme na ame, siwo wozãna le nu me, ŋɔti me atikewo, ŋkumeɖonuwo, tomekawo, kple atike siwo wotsɔna tsia tsii me.
Le avɔlɔ̃ƒewo kple pepadɔwɔƒewo la, wozãa alkyl polyethers abe nusiwo naa nu fa, nusiwo tsia dzoxɔxɔ nu, kple nusiwo naa tsi nɔa lãme na ame ene. Wona avɔwo ƒe fafɛ kple woƒe tsitretsitsi ƒe nɔnɔme nyona ɖe edzi eye wodoa pepa ƒe nyonyome kple ewɔwɔ nyuie ɖe ŋgɔ le pepawɔwɔ me.
Le atike siwo wotsɔna klɔa nu kple ame ŋutɔ ƒe belélenamenuwo ƒe akpawo me la, wozãa alkyl polyethers abe nusiwo wotsɔna klɔa nu kple nusiwo wotsɔna ƒoa ƒui ene. Woɖea dzadzɛnyenye, futukpɔ, futukpɔ ƒe liƒo, tsidede, kple eƒe ʋeʋẽ ƒe ŋutete nyui fiana, wozãa wo geɖe le atike siwo wotsɔna klɔa nu, ŋutilãklɔ, asikɔklɔ, kple atike siwo wotsɔna klɔa nu me.
Tsɔ kpe ɖe eŋu la, wozãa alkyl polyethers abe ami ɖeɖeɖa kple ami ene le amidɔwɔƒewo, kpakple fafa kple ami le gaŋutiɖoɖo me.
Zi geɖe la, alkyl polyethers wɔwɔ ƒe mɔnu lɔa dɔwɔwɔ do ŋgɔ na gɔmedzenuwo kple nusiwo naa nu ʋãna, ring-opening polymerization reactions, kple dɔwɔwɔ megbe afɔɖeɖewo abe neutralization, adsorption, dehydration, filtration, kple distillation ene ɖe eme.
