Polyols: Nusiwo Wozãna Le Taɖodzinu Geɖewo Me Na Dɔwɔƒewo Kple Nuƒlelawo ƒe Dɔwɔwɔ
Dɔwɔwɔ ƒe Agble Gãwo
Le atikewɔƒewo la, polyol nye nu vevi siwo wozãna tsɔ wɔa nusiwo ƒe molecule ƒe kpekpeme lolo abe polyesters, polyethers, kple polyurethanes ene. Le kpɔɖeŋu me, wozãa ethylene glycol tsɔ wɔa polyethylene terephthalate (PET), si wozãna geɖe le aŋetuwo kple kawo me. Wozãa polyethylene glycol (PEG) tsɔ wɔa ami vovovowo kple ami siwo wotsɔna ƒoa ƒui. Tsɔ kpe ɖe eŋu la, polyol ate ŋu awɔ dɔ abe atike ene atsɔ alɔ nu vovovo siwo me lãmenugbagbeviwo le, si ana woawɔ dɔ nyuie wu.
Le atikewɔƒewo la, wozãa polyol geɖe abe atike siwo wotsɔna tsia atikewoe, nusiwo wotsɔna ƒoa ƒui, kple nusiwo naa tsi nɔa lãme na ame ene. Le kpɔɖeŋu me. Tsɔ kpe ɖe eŋu la, woate ŋu azã polyols atsɔ awɔ atike siwo woɖena ɖe go si dzi wokpɔna, si ana atikewo ƒe dodo ƒe agbɔsɔsɔme naɖɔ ɖo.
Le nuɖuɖudɔwɔƒewo la, wozãa polyols abe vividoɖeameŋunuwo, tsi si naa tsi nɔa lãme na ame, kple nusiwo naa nu vivina ene. Le kpɔɖeŋu me, woate ŋu azã glycerol kple polyethylene glycol le nuɖuɖuvivinuwo, abolo siwo woɖa, kple ahanonowo wɔwɔ me, si ana woavivi eye tsi nalé wo ɖe te. Tsɔ kpe ɖe eŋu la, woate ŋu azã polyols atsɔ atrɔ asi le nuɖuɖu ƒe nɔnɔme kple nu me ƒe seselelãme ŋu, si ana eƒe agbenɔƒe nadidi ɖe edzi.
Le atsyɔ̃ɖomi kple ŋutigbalẽlénuwo ƒe dɔwɔƒewo la, wozãa polyol geɖe abe tsilénu kple ŋutigbalẽ ƒe ʋeʋẽ ene. Le kpɔɖeŋu me, propylene glycol kple glycerol ate ŋu axɔ tsi, si ana tsi nanɔ ŋutigbalẽ kple ɖa me. Tsɔ kpe ɖe eŋu la, woate ŋu azã polyols le ɣe ƒe keklẽŋusẽtikewo, atike siwo wotsɔna tsia ɖae, kple atike siwo wotsɔna dzraa ɣe ƒe keklẽŋusẽtikewo wɔwɔ me, si ana woade tsi ahasi ami wo.
Le plastikdɔwɔƒewo la, wozãa polyols abe plasticizers ene be woatsɔ ana plasticwo nate ŋu atrɔ ɖe nɔnɔmewo ŋu eye woate ŋu awɔ wo ŋu dɔ nyuie wu. Le kpɔɖeŋu me, woate ŋu azã glycerol kple polyethylene glycol abe plasticizers ene na polyvinyl chloride (PVC), si ana eƒe asitɔtrɔ le nɔnɔmewo ŋu nyuie wu eye wònɔa anyi didina. Tsɔ kpe ɖe eŋu la, woate ŋu azã polyols atsɔ awɔ plastic siwo gblẽna le nugbagbeviwo ŋu, si aɖe ŋusẽ si wòagblẽ le nutome ŋu dzi akpɔtɔ.
Le nusiwo wotsɔ blaa nu kple nuŋlɔtsi dɔwɔƒewo me la, wozãa polyols abe atike siwo wotsɔna tsia nu kple nusiwo wotsɔna ƒoa nu ene. Woate ŋu alɔ aŋɔ kple amadede vovovowo, si ana woate ŋu awɔ film nyuie. Le kpɔɖeŋu me, woate ŋu azã polyethylene glycol atsɔ awɔ nusiwo wotsɔ tsyɔa nu kple nuŋlɔtsi siwo wotsɔ tsi wɔe, si ana woakpɔ egbɔkpɔnu siwo megblẽa nu le nutome ŋu o eye wowɔa dɔ nyuie.
