1 Moetso oa lisebelisoa tse kopaneng tsa Glass, o sebelisoang likarolong tse fapaneng tsa moruo oa naha

1.1 Fiber ea khalase - lisebelisoa tse phahameng tsa ts'ebetso tse se nang tšepe

Lisebelisoa tse phahameng tsa khalase ea fiber, mefuta e mengata ea likopo.Glass fiber e hlahile ka bo-1930, ke pyrophyllite, lehlabathe la quartz, lejoe la mokoetla, dolomite, borite, boromite le lisebelisoa tse ling tse ka sehloohong tsa liminerale tse tala le boric acid, molora oa soda le lisebelisoa tse ling tsa lik'hemik'hale tse hlahisoang ke lihlahisoa tse sa sebelisetsoeng tšepe.Ka boima bo bobebe, matla a phahameng, ho hanyetsa mocheso o phahameng le o tlase, ho hanyetsa kutu, ho thibela mocheso, ho thibela lelakabe, ho monya molumo, ho kenya motlakase le lisebelisoa tse ling tse babatsehang le tekanyo e itseng ea sebopeho sa ts'ebetso, ke thepa e babatsehang ea ts'ebetso le thepa ea sebopeho.Lilemong tsa morao tjena, thepa e matlafalitsoeng ea khalase ea thermoplastic e tsoetse pele ka potlako, 'me lihlahisoa tse ncha tse kang lisebelisoa tsa kaho tse matlafalitsoeng tsa khalase, fiber e khuts'oane le lisebelisoa tse matlafalitsoeng tse telele li fetohile lintlha tse ncha tsa nts'etsopele ea indasteri ea fiber ea khalase.Tšebeliso ea fiber ea khalase e atolohile ho tloha masimong a setso a indasteri joalo ka thepa ea kaho, lisebelisoa tsa elektroniki, lipalangoang tsa terene, petrochemical, tlhahiso ea likoloi ho ea libakeng tse ntseng li hlaha joalo ka sefofane, ho fehla matla a moea, ho tlhotla le ho tlosa lerōle, boenjiniere ba tikoloho le boenjiniere ba leoatle.

Molao-motheo oa lihlopha o fapane, 'me mefuta ea fiber ea khalase e fapane.Ho ea ka mofuta o fapaneng oa sehlahisoa le ts'ebetso ea tlhahiso, lihlahisoa tsa fiber tsa khalase tsa k'hamphani li ka aroloa ka likhoele tsa roving, spun, lihlahisoa tsa roving, lihlahisoa tsa spun khoele mekhahlelo e mene.Roving e kenyelletsa khoele e otlolohileng, khoele ea ply le khoele e khaotsoeng;Khoele e ntle e ka aroloa ka khoele ea pele e sothehileng, khoele e sothehileng habeli, khoele e ngata le khoele e otlolohileng.Lihlahisoa tsa roving li kenyelletsa lesela la li-axial tse ngata, lesela la plaid, le ikutloang;Lihlahisoa tsa likhoele tse ntle li kenyelletsa lesela la elektroniki le lesela la indasteri.Ho latela lisebelisoa tse fapaneng tsa matrix resin tse tsamaellanang, e ka aroloa ka fiber ea khalase ea thermosetting le fiber ea khalase ea thermoplastic mekhahlelo e 'meli.

Li-resin tsa matrix tse tsamaellanang le fiber ea khalase bakeng sa thermosetting resin ke phenolic resin, urea-formaldehyde resin, epoxy resin, unsaturated resin, polyurethane joalo-joalo.Resin ea Thermosetting ke polymer ea linear kapa branched-chain pele e phekoloa, 'me ka mor'a ho phekola mocheso, maqhama a lik'hemik'hale a thehoa pakeng tsa liketane tsa limolek'hule hore e be sebopeho sa marang-rang a mararo, se entsoeng hang' me se ke ke sa futhumatsa hape.Haholo-holo e sebelisoa masimong a hlokang ho finyella mocheso oa mocheso, ho hanyetsa ho roala, ho kenya letsoho, matla a phahameng a matla le liphello tse ling, tse kang li-blades tsa moea le mapolanka a potoloho.

Li-resin tsa matrix tse tsamaellanang le fiber ea khalase bakeng sa resin ea thermoplastic ke haholo-holo polyolefin, polyamide, polyester, polycarbonate, polyformaldehyde joalo-joalo.Thermoplastic resin ke boima bo phahameng ba limolek'hule bo tiileng mochesong oa kamore, ke polymer ea linear kapa tse seng kae tse nang le makala, ha li kopane pakeng tsa limolek'hule, feela ka matla a van der Waals kapa hydrogen bond ho hohelana.Ts'ebetsong ea ho bōptjoa, resin ea thermoplastic e nolofatsoa 'me e phalla ka mor'a ho futhumala ha khatello, ntle le lik'hemik'hale tse fapa-fapaneng,' me e ka bōptjoa ka har'a hlobo, 'me lihlahisoa tse nang le sebōpeho se hlokahalang li ka etsoa ka ho pholile.E sebelisoa haholo ho fihlela boima, ho hanyetsa kutu, ho hanyetsa mokhathala le litlamorao tse ling tsa tšimo, joalo ka tlhahiso ea likoloi, lisebelisoa tsa ntlo, lisebelisoa tsa elektroniki, thepa ea kaho.Ka mor'a hore motsoako oa fiber ea khalase ea thermoplastic e folisoe 'me e pholisoe, e ntse e ka khona ho fihlela metsi ka ho futhumatsa hape 'me e khona ho sebelisoa hape.

Sebōpi sa tanka ea tlhahiso ea fiber ea khalase ke eona e ka sehloohong e toroang ka terata e tlosoang butle-butle 'marakeng.Ho na le mekhoa e 'meli ea mantlha ea tlhahiso ea fiber ea khalase, e arotsoeng ka mekhoa e' meli - mokhoa oa ho taka ka terata ea crucible le mokhoa o le mong oa ho taka - mokhoa oa ho taka ka terata ea letamo.Mokhoa oa ho taka oa terata ea Crucible: mokhoa ona o rarahane, lisebelisoa tse tala tsa khalase li qhibilihisoa ka bolo ea khalase ka mocheso o phahameng, ebe bolo ea khalase e qhibiliha habeli, 'me setšoantšo sa terata se lebelo le phahameng se etsoa ka khoele ea fiber ea khalase.Mokhoa oa ho taka ka terata ea letamo: lisebelisoa tse tala tse kang pyrophylla li qhibilihisoa ka sebōping ho etsa tharollo ea khalase, 'me li-bubble lia tlosoa ebe li isoa poleiti ea porous leakage ka mocha,' me fiber ea khalase e huloa ka lebelo le phahameng.Sebōpi se ka kopanya lipoleiti tse makholo tse lutlang ka likanale tse ngata ka nako e le 'ngoe.Ha ho bapisoa le mokhoa oa ho taka terata ea crucible, mokhoa oa ho taka terata ea pool kiln o bonolo, o boloka matla le ho fokotsa tšebeliso ea matla, sebopeho se tsitsitseng, ts'ebetso e phahameng le chai e ngata, 'me e loketse tlhahiso e kholo ea boiketsetso, e fetohileng tlhahiso e tloaelehileng ea machaba. ts'ebetso, 'me boholo ba fiber ea khalase bo hlahisoang ke ts'ebetso ena bo nka karolo e fetang 90% ea tlhahiso ea lefats'e.
