Faeba ea khalase (lebitso la pele ka Senyesemane: faeba ea khalase kapa fiberglass) ke thepa e seng ea tšepe e sa pheleng e nang le ts'ebetso e ntle haholo. E na le melemo e mengata e fapaneng. Melemo ke ho thibela mocheso hantle, ho hanyetsa mocheso ka matla, ho hanyetsa ho bola hantle, le matla a phahameng a mechini, empa bothata ke ho brittle, ho hanyetsa ho tsofala ho fokolang. Faeba ea khalase hangata e sebelisoa e le thepa e matlafatsang thepa e kopaneng, thepa ea ho thibela mocheso ka motlakase le thepa ea ho thibela mocheso, liboto tsa potoloho le masimo a mang a moruo oa naha.

Morero o ka sehloohong oa Fiberglass Roving ke ofe?
Khoele ea faeba ea khalase e sebelisoa haholo-holo e le thepa ea ho thibela motlakase, thepa ea sefe ea indasteri, e thibelang mafome, e thibelang mongobo, e thibelang mocheso, e thibelang molumo, thepa ea ho monya tšisinyeho, 'me e ka boela ea sebelisoa e le thepa e matlafatsang. Tšebeliso ea khoele ea faeba ea khalase e pharaletse haholo ho feta mefuta e meng ea likhoele ho etsa matlafatso. Plastiki, khoele ea faeba ea khalase kapa rabara e matlafalitsoeng, plaster e matlafalitsoeng, samente e matlafalitsoeng le lihlahisoa tse ling. Khoele ea faeba ea khalase e koahetsoe ka thepa ea tlhaho ho ntlafatsa ho tenyetseha ha eona 'me e sebelisoa ho etsa lesela la ho paka, ho sireletsa lifensetere, ho koahela lebota, lesela le koahelang, le liaparo tse sireletsang. Le thepa ea ho thibela mocheso le ho thibela molumo.

Mokhoa oa ho khetholla boleng ba Fiberglass Roving?  
Faeba ea khalase e entsoe ka khalase e le thepa e tala 'me e sebetsoa ka mekhoa e fapaneng ea ho bopa boemong bo qhibilihisitsoeng. Ka kakaretso e arotsoe ka faeba ea khalase e tsoelang pele le faeba ea khalase e sa khaotseng. 'Marakeng, ho sebelisoa lifaeba tse ling tsa khalase tse tsoelang pele. Ho na le lihlahisoa tse peli tse kholo tsa faeba ea khalase e tsoelang pele. E 'ngoe ke faeba ea khalase ea alkali e mahareng, e bitsoang C; e 'ngoe ke faeba ea khalase e se nang alkali, e bitsoang E. Phapang e kholo lipakeng tsa tsona ke litaba tsa li-oxide tsa tšepe tsa alkali. Faeba ea khalase ea alkali e mahareng ke (12±0.5)%, 'me faeba ea khalase e se nang alkali ke <0.5%. Hape ho na le sehlahisoa sa faeba ea khalase e seng ea maemo a tloaelehileng 'marakeng. E tsejoang hangata e le faeba ea khalase ea alkali e phahameng. Li-oxide tsa tšepe tsa alkali li ka holimo ho 14%. Lisebelisoa tse tala tsa tlhahiso ke khalase e senyehileng kapa libotlolo tsa khalase. Mofuta ona oa faeba ea khalase o na le khanyetso e fokolang ea metsi, matla a tlase a mechini le ho thibela motlakase ho tlase, e sa lumelloeng ho hlahisoa ke melao ea naha.

Lihlahisoa tsa khoele ea khalase ea fiber e mahareng le e se nang alkali tse tšoanelehang ka kakaretso li tlameha ho tlangoa ka thata holim'a bobine, 'me bobine ka' ngoe e tšoailoe ka nomoro, nomoro ea khoele le sehlopha, 'me netefatso ea tlhahlobo ea sehlahisoa e lokela ho etsoa ka lebokoseng la ho paka. Litaba tsa tlhahlobo le netefatso ea sehlahisoa li kenyelletsa:
1. Lebitso la moetsi;
2. Khoutu le kereiti ea sehlahisoa;
3. Palo ea tekanyetso ena;
4. Setempe se nang le tiiso e khethehileng bakeng sa tlhahlobo ea boleng;
5. Boima ba 'nete;
6. Lebokose la ho paka le lokela ho ba le lebitso la fektheri, khoutu ea sehlahisoa le kereiti, nomoro e tloaelehileng, boima ba 'nete, letsatsi la tlhahiso le nomoro ea sehlopha, jj.
