Ka lebaka la tlatsetso eale glassfiber, polasetiki e matlafalitsoeng ea fiber ea khalase e se e le opaque, 'me e pepenene pele e eketsa fiber ea khalase.
Plastiki e matlafalitsoeng ka khalase ea khalase e na le ho tiea ho tlase le ho eketseha ha brittleness ho feta polasetiki e se nang fiber ea khalase;
Ka lebaka la ho eketsoa ha fiber ea khalase, viscosity e qhibilihisitsoeng ea lisebelisoa tsohle e ea eketseha, metsi a fetoha a futsanehileng, 'me khatello ea ente e phahame haholo ho feta ntle le fiber ea khalase.Bakeng sa ho bopa ka mokhoa o tloaelehileng oa ente, mocheso oa ente oa li-plastiki tsohle tse matlafalitsoeng o phahame ho feta ntle le ho eketsa fiber ea khalase.Fiber ea khalase e kile ea phahamisoa ke 10 ℃-30 ℃.
Ka lebaka la ho eketsoa ha fiber ea khalase le li-additives, thepa ea hygroscopic eakhalase ea fiberglass lipolasetiki tse matlafalitsoeng li ntlafatsoa haholo.Li-plastiki tsa pele tse hloekileng tse sa monyeng metsi le tsona li tla monya.Ka hona, li tlameha ho omisoa nakong ea ente.
Nakong ea ts'ebetso ea ho etsa ente ea polasetiki e matlafalitsoeng ea fiber ea khalase, fiber ea khalase e ka kena ka holim'a sehlahisoa sa polasetiki, e leng se etsang hore bokaholimo ba sehlahisoa bo be mahlahahlaha le bo matheba.E le ho finyella boleng bo phahameng ba holim'a metsi, mochine oa mocheso oa hlobo o sebelisoa ho futhumatsa hlobo nakong ea ho bōptjoa ha ente, e le hore polima ea polasetiki e kene ka holim'a sehlahisoa, empa ponahalo ea boleng ba polasetiki e hloekileng e ke ke ea finyelloa.
Ka mor'a hore fiber ea khalase e matlafatsoe,e khalase fiberglass ke ntho e nang le boima bo phahameng.Ka mor'a hore motsoako o fokotsehe ka mocheso o phahameng, ke khase e senyang haholo, e bakang ho senyeha ho hoholo le ho senyeha ha sekoti le hlobo ea ente ea mochine oa ente.Ka hona, mofuta ona oa thepa o sebelisoa tlhahisong.Ha u sebelisa liforomo le mochini oa ho etsa ente, ela hloko kalafo e khahlanong le kutu le kalafo ea ho thatafala ha holim'a lisebelisoa.
Matlafatso a matla a fiber ea khalase holim'a nylon
Nylon, eo hape e tsejoang e le polyamide, ke thepa ea maiketsetso e nang le mefuta e mengata ea lits'ebetso, e sebelisoang ho masela, ho paka, likarolo tsa mochini le masimo a mang.
Joaloka polasetiki ea boenjiniere, PA66 e na le palo e kholo ea lihlopha tsa hydrophilic amide, tse fokotsang sebaka sa ts'ebeliso ea eona.E atisa ho sebelisoa indastering ho e fetola ka ho sebelisa copolymerization, ho kopanya toughening, le ho matlafatsa.
