I-Furfuryl alcohol ne-ethanol ihluke ngokuyinhloko ezakhiweni zabo zamangqamuzana.
1. Yini i-furfuryl alcohol ne-ethanol?
I-Furfuryl alcohol iyi-polyol equkethe amaqembu amathathu e-hydroxyl, enefomula evamile C6H(CHOH)3OH. Isetshenziswa kakhulu ekukhiqizeni odayi nama-resin. Ngakolunye uhlangothi, i-ethanol iyi-diol, ngokuvamile ibhekisela ku-ethanol noma izixazululo ze-ethanol, futhi iyisincibilikisi esivamile sezinto eziphilayo kanye nophethiloli.
2. Umehluko Phakathi Kwe-Furfuryl Alcohol ne-Ethanol
Nakuba kokubili i-furfuryl alcohol ne-ethanol kuyizinhlanganisela zotshwala, izakhiwo zazo zamangqamuzana ziyahlukahluka. I-Furfuryl alcohol iqukethe amaqembu amathathu e-hydroxyl, kuyilapho i-ethanol inelilodwa kuphela. Lokhu kubangela izakhiwo ezahlukene zomzimba nezamakhemikhali ze-furfuryl alcohol ne-ethanol.
Omunye umehluko yizicelo zabo. I-Ethanol iyi-solvent esetshenziswa kabanzi yezinto eziphilayo kanye nophethiloli, kuyilapho i-furfuryl alcohol isetshenziswa ngokuyinhloko ekukhiqizeni odayi nama-resin.
3. Izakhiwo ze-Furfuryl Alcohol ne-Ethanol
I-Furfuryl alcohol kanye ne-ethanol nayo ihlukile ngezakhiwo zayo ezingokomzimba namakhemikhali. I-Furfuryl alcohol iwuketshezi olungenambala, olunamehlo abukeka ekamelweni lokushisa olunephuzu elibilayo elingama-degree angu-300. I-Ethanol iwuketshezi oluvuthayo, olungenambala nephuzu elibilayo elingu-78℃ekamelweni lokushisa.
Ngaphezu kwalokho, ukuncibilika kwazo emanzini kuyehluka. I-Furfuryl alcohol ine-solubility ephansi emanzini, kuyilapho i-ethanol ine-solubility ephakeme kakhulu.
IV. Ukusetshenziswa kwe-Furfuryl Alcohol ne-Ethanol
I-Furfuryl alcohol isetshenziswa ngokuyinhloko ekukhiqizeni odayi nama-resin, futhi ingasetshenziswa ekulungiseleleni ama-polyester resins. I-Ethanol isetshenziswa kakhulu kuzincibilikisi, izinto zokubasa, izithuthukisi ukunambitheka, nezimonyo.
Sekukonke, nakuba kokubili i-furfuryl alcohol ne-ethanol kuyizinhlanganisela zotshwala, zihluka kakhulu, kusukela ezinhlakeni zazo zamangqamuzana kuya ezintweni zazo ezingokomzimba namakhemikhali kanye nokusetshenziswa kwazo.
