Litšobotsi tsa mantlha tsa fiber ea khalase li kenyelletsa lintlha tse latelang:
Ha ho bonolo ho monya metsi:Faeba ea khalase e thibela metsi 'me ha ea lokela liaparo, hobane mofufutso o ke ke oa monngoa, e leng se etsang hore motho ea e apereng a ikutloe a le metsi; hobane thepa ha e angoe ke metsi, e ke ke ea fokotseha

E ka angoa habonolo:Likhoele tsa khalase li angoa ke asiti ea hydrofluoric le asiti e chesang ea phosphoric. Kaha faeba ke sehlahisoa se entsoeng ka khalase, likhoele tse ling tsa khalase tse tala li lokela ho tšoaroa ka hloko, joalo ka thepa ea ho thibela mocheso ea lapeng, hobane lipheletso tsa faeba lia fokola 'me li ka phunya letlalo, kahoo liatlana li lokela ho aparoa ha ho sebetsoa fiberglass.
3. Ts'ebetso ea tlhahiso ea faeba ea khalase
Faeba ea khalaseke faeba e seng ya tshepe e sebediswang haholo hajwale e le thepa ya indasteri. Ka kakaretso, thepa ya motheo ya fiber ya khalase e kenyeletsa diminerale tse fapaneng tsa tlhaho le dikhemikhale tse entsweng ke motho, dikarolo tse ka sehloohong ke lehlabathe la silica, lejwe la mokoetla le molora wa soda.
Lehlabathe la silika le sebetsa e le khalase e betliloeng, ha molora oa soda le lejoe la mokoetla li thusa ho fokotsa mocheso o qhibilihang. Koefficient e tlase ea katoloso ea mocheso e kopantsoeng le conductivity e tlase ea mocheso ha e bapisoa le asbestos le likhoele tsa organic e etsa hore fiberglass e be thepa e tsitsitseng ka tekanyo e felisang mocheso kapele.
Likhoele tsa khalaseLi hlahisoa ka ho qhibiliha ka ho toba, ho kenyeletsang lits'ebetso tse kang ho kopanya, ho qhibilihisa, ho ohla, ho koahela, ho omisa le ho paka. Sehlopha ke boemo ba pele ba tlhahiso ea khalase, moo bongata ba thepa bo tsoakiloeng ka botlalo ebe motsoako o romeloa seboping bakeng sa ho qhibilihisa mochesong o phahameng oa 1400°C. Mocheso ona o lekane ho fetola lehlabathe le metsoako e meng hore e be boemo bo qhibilihisitsoeng; khalase e qhibilihisitsoeng ebe e phalla ka har'a mochini o hloekisang 'me mocheso o theohela ho 1370°C.
Nakong ea ho phethoha ha likhoele tsa khalase, khalase e qhibilihisitsoeng e phalla ka har'a sleeve e nang le masoba a manyenyane haholo. Poleiti ea liner e futhumatsoa ka elektroniki 'me mocheso oa eona o laoloa ho boloka viscosity e sa fetoheng. Ho ile ha sebelisoa jete ea metsi ho pholisa filament ha e tsoa sleeve mochesong oa hoo e ka bang 1204°C.

Ho na le khatello e sebelisoang ka ho sebelisa sesebelisoa sa ho betla se lebelo le phahameng 'me khalase e qhibilihisitsoeng e huloa ho ea ho li-filament. Mokhahlelong oa ho qetela, ho sebelisoa lik'hemik'hale tse koahelang mafura, li-binder le li-coupling agents ho li-filament. Ho tlotsa ho thusa ho sireletsa li-filament ho tsoa maqebeng ha li bokelloa 'me li kobeha ka har'a liphutheloana. Kamora ho etsa boholo, li-filament li omisoa ka ontong; li-filament li se li loketse ho sebetsoa hape ho ea ho li-filament tse khaotsoeng, li-roving kapa likhoele.
