Isifinyezo
I-OBF-FLC22 yamukela umqondo wesakhiwo samangqamuzana ukuze kuthuthukiswe ukuqina kwama-molecule e-copolymer, futhi iyunithi yokuphinda ye-monomer eyethulwe inevolumu yesikhala esikhulu, engakhuphula ngempumelelo isithiyo esiqinile futhi ithuthukise umphumela wokunciphisa ukulahlekelwa kokuhlunga kwe-HTHP komkhiqizo.Ngesikhathi esifanayo, ngokukhethwa kwezinga lokushisa nosawoti ukumelana ne-monomer, ikhono lokushisa ne-calcium ukumelana nosawoti lathuthukiswa nakakhulu.Umkhiqizo unqoba ukushiyeka kwesinciphisi esivamile sokulahlekelwa uketshezi lwe-polymer, njengokungazweli kahle kwe-shear, ukumelana ne-calcium kasawoti okungekuhle kanye nomthelela ongagculisi wokunciphisa ukulahlekelwa uketshezi lwe-HTHP.Yisinciphisi esisha sokulahlekelwa uketshezi lwe-polymer.
Ukucaciswa Kwezobuchwepheshe

Izici
I-OBF-FLC22 inokumelana nosawoti okuqinile.Ngokuhlolwa kwaselabhorethri, okuqukethwe kukasawoti ohlelweni loketshezi lokumba olusetshenziselwa ukuhlolwa kwalungiswa, futhi ukumelana nosawoti womkhiqizo we-OBF-FLC22 kwaphenywa ngemva kokuguga ku-200℃ ku-base slurry enokuqukethwe kukasawoti okuhlukile.
I-OBF-FLC22 inokuqina okuhle kakhulu kwe-thermal.Ocwaningweni lwaselabhorethri, izinga lokushisa lokuguga le-OBF-FLC22 liye lenyuka kancane kancane ukuze kuphenywe umkhawulo wokumelana nezinga lokushisa lemikhiqizo ye-OBF-FLC22 ku-30% kasawoti slurry.
I-OBF-FLC22 inokuhambisana okuhle.Ukusebenza kwe-OBF-FLC22 eneminyaka engu-200℃ emanzini olwandle, usawoti oyinhlanganisela kanye nezinhlelo zoketshezi lokumba usawoti ogcwele usawoti kwaphenywa ngokuhlolwa kwaselabhorethri.
