Optical fiber e tlatsang Jelly
Tlhaloso e Khutšoanyane:
Indasteri ea optical fiber cable e etsa likhoele tsa optical fiber ka ho koala likhoele tsa optical ka har'a sheathing ea polymeric.Jelly e behoa pakeng tsa polymeric sheathing le fiber optical.Sepheo sa jelly ena ke ho fana ka ho hanyetsa metsi le ho thibela ho koba likhatello le mathata.Lisebelisuoa tse tloaelehileng tsa ho roala li-polymeric ka tlhaho tse nang le polypropylene (PP) le polybutylterepthalate (PBT) e leng lisebelisoa tse sebelisoang ka ho fetisisa.Hangata jelly ke oli e seng ea Newtonian.
Sebopeho se seng sa Newtonian se lumella jelly hore e tšesaane nakong ea ts'ebetso le ho behoa ka mor'a hore ho tlosoe matla a ho kuta.Mekhahlelo ea bohlokoa e fanang ka ts'ebetso e hlokahalang ke viscosity ka litekanyetso tse fapaneng tsa ho kuta le khatello ea chai.Ka tloaelo jelly e etsoa ho sebelisoa oli le inorganic kapa organic thickener.Li-thickeners tsa inorganic tse sebelisoang ho tloha ho letsopa ho isa ho silika.Li-thickeners tsena li emisoa ka oli ea hydrophobic joalo ka oli ea diminerale kapa oli ea maiketsetso.Ho feta moo, li-stabilizer li ka kenyelletsoa ho netefatsa botsitso ba oxidative ea motsoako.
● XF-400 e lumellana le liaparo tsa acrylic resin le lisebelisoa tsa polymer bakeng sa lisebelisoa tsa fiber le cable.
● Ho khothalletsoa hore lisebelisoa tsohle tsa polymer tse amanang le pente li lekoe bakeng sa ho lumellana nakong ea tšebeliso.
● XF-400 e etselitsoe mokhoa o batang oa ho tlatsa o qobang li-voids ka lebaka la ho fokotseha ha peista.
