Ingabe uyazi ngempela ngezindwangu ze-acetate?
I-acetate fiber, etholakala ku-acetic acid kanye ne-cellulose ngokusebenzisa i-esterification, iyifayibha eyenziwe umuntu elingisa eduze izimfanelo zikasilika zikanokusho.Lobu buchwepheshe bendwangu obuthuthukisiwe bukhiqiza indwangu enemibala egqamile, ukubukeka okukhazimulayo, nokuzwakala okubushelelezi, okunethezekile.Izakhiwo zayo zamakhemikhali nezomzimba ziyenza ibe yinto eguquguqukayo futhi ehlala isikhathi eside yezinhlelo zokusebenza ezahlukahlukene.
Ngokuphathelene nezakhiwo zamakhemikhali, i-acetate fiber ibonisa ukumelana okuphawulekayo kokubili i-alkaline nama-ejenti ane-asidi, okwenza kube ukukhetha okuqinile ezindaweni eziningi.Nokho, ukudaya kwawo kuletha inselele eyingqayizivele, njengoba odayi bendabuko be-cellulose benokuhlangana okulinganiselwe kwemicu ye-acetate, okwenza kube nzima ukudaywa.
Izakhiwo ezingokomzimba ze-acetate fiber zithuthukisa ukukhanga kwayo.Ngokuzinza okuhle kwe-thermal, i-fiber ingakwazi ukumelana nezinga lokushisa elifika ku-185 ° C ngaphambi kokufinyelela izinga lokushisa lokushintsha kwengilazi, futhi lizungeze ku-310 ° C ngaphambi kokuncibilika.Nakuba ibonisa ukushwabana okuphansi emanzini abilayo, ukwelashwa okunezinga lokushisa eliphezulu kungaba nomthelela emandleni ayo kanye nokucwebezela kwayo, okudinge ukuphathwa ngokucophelela ukuze kugcinwe ubuqotho bayo.
Ngokuphawulekayo, i-acetate fiber ibuye ibe nokunwebeka okuhle uma kuqhathaniswa, okufana nosilika noboya, okunezela ezinhlobonhlobo nokunethezeka kwayo.
Ukuqonda izici eziyingqayizivele ze-acetate fiber kubalulekile ekukhuliseni amandla ayo ezimbonini ezihlukahlukene, kusukela kumfashini nezindwangu kuya ekuhlungeni nangale kwalokho.Ikhono layo lokulingisa izimfanelo zikasilika eziwubukhazikhazi kuyilapho inikeza izinzuzo ezihlukile ngokwezinto zamakhemikhali nezomzimba lenza into efunwa kakhulu ukuze isetshenziswe ezinhlobonhlobo.Njengoba ubuchwepheshe kanye nokuqanjwa okusha kuqhubeka kuqhubekisela phambili intuthuko ekukhiqizweni kwezindwangu, i-acetate fiber ima njengobufakazi bobuhlakani kanye nokuguquguquka kwemicu eyenziwe umuntu.
