Fiber ea khalase e na le thepa e ntle haholo 'me e sebelisoa haholo mafapheng a mangata. Ke ntho e sa sebetseng e seng ea tšepe e ka nkang sebaka sa tšepe sebaka. Ka lebaka la tebello ea eona e ntle ea nts'etsopele, lik'hamphani tse kholo tsa fiber fiber li tsepamisitse maikutlo ho lipatlisiso mabapi le ts'ebetso e phahameng le ts'ebetso ea ntlafatso ea fiber ea khalase.
1 Tlhaloso ea fiber ea khalase
Glass fiber ke mofuta oa inorganic non-metallic material e ka nkelang tšepe sebaka 'me e na le ts'ebetso e ntle haholo. E lokisoa ka ho hula khalase e qhibilihisitsoeng ka har'a likhoele ka ketso ea matla a kantle. E na le litšobotsi tsa matla a phahameng, modulus e phahameng le elongation e tlaase. Ho hanyetsa mocheso le ho hatelloa ha mocheso, tekanyo e kholo ea ho atolosa mocheso, sebaka se phahameng sa ho qhibiliha, mocheso oa eona o bonolo o ka fihla ho 550 ~ 750 ℃, botsitso bo botle ba lik'hemik'hale, ha ho bonolo ho chesa, bo na le litšobotsi tse itseng tse babatsehang tse kang ho hanyetsa kutu, 'me e sebelisitsoe haholo libakeng tse ngata. .
2 Litšobotsi tsa fiber ea khalase
Sebaka se qhibilihang sa fiber ea khalase ke 680 ℃, ntlha e belang ke 1000 ℃, 'me boima ke 2.4 ~ 2.7g/cm3. Matla a matla ke 6.3 ho 6.9 g / d sebakeng se tloaelehileng le 5.4 ho 5.8 g / d sebakeng sa metsi.Khalase ea fiber e na le mocheso o motle oa ho hanyetsa mocheso 'me ke lisebelisoa tse phahameng tsa ho thibela mocheso tse nang le lisebelisoa tse ntle, tse loketseng bakeng sa tlhahiso ea mocheso oa mocheso le lisebelisoa tsa mollo.
3 Sebopeho sa fiber ea khalase
Khalase e sebelisoang ho hlahisa likhoele tsa khalase e fapane le khalase e sebelisoang lihlahisoa tse ling tsa khalase. Khalase e sebelisoang ha ho etsoa likhalase tsa khalase e na le likarolo tse latelang:
(1)Khalase ea elektroniki,e tsejoang hape e le khalase e se nang alkali, ke ea khalase ea borosilicate. Har'a lisebelisoa tse sebelisoang hona joale ha ho etsoa likhalase tsa khalase, khalase e se nang alkali ke eona e sebelisoang ka ho fetisisa. Khalase e se nang alkali e na le insulation e ntle le thepa ea mochini, 'me e sebelisoa haholo-holo ho hlahisa likhoele tse sireletsang khalase le likhoele tsa khalase tse matla haholo, empa khalase e se nang alkali ha e hanyetsane le kutu ea inorganic acid, ka hona ha e loketse ho sebelisoa libakeng tse nang le asiti. . Re na le khalase ea elektronikifiberglass roving, khalase ea efiberglass lohiloeng roving,le e-glassmatheba a fiberglass.
(2)Khalase ea C, e tsejoang hape e le khalase ea alkali e mahareng. Ha e bapisoa le khalase e se nang alkali, e na le khanyetso e ntle ea lik'hemik'hale le lisebelisoa tse mpe tsa motlakase le tsa mochini. Ho eketsa diboron trichloride ho khalase ea alkali e bohareng e ka hlahisaglass fiber surface mat,e nang le ditshobotsi tsa ho hanyetsa ho bola. Boron-free medium-alkali glass fibers li sebelisoa haholo-holo tlhahiso ea masela a sefa le masela a phuthelang.
(3)fiber ea khalase e matla haholo,joalo ka ha lebitso le bontša, fiber ea khalase e matla e phahameng e na le litšobotsi tsa matla a phahameng le modulus e phahameng. Matla a eona a ho tiea ha fiber ke 2800MPa, e ka bang 25% e phahameng ho feta ea fiber ea khalase e se nang alkali, 'me modulus ea eona ea elastic ke 86000MPa, e phahameng ho feta ea fiber ea E-glass. Sehlahisoa sa fiber ea khalase e matla haholo ha e phahame, e kopantsoe le matla a eona a phahameng le modulus e phahameng, kahoo e sebelisoa ka kakaretso ho lisebelisoa tsa sesole, sefofane le lipapali le masimo a mang, 'me ha e sebelisoe haholo libakeng tse ling.
(4)AR khalase fiber, eo hape e tsejoang e le fiber ea khalase e hanyetsanang le alkali, ke fiber e sa tloaelehang. Fiber ea khalase e hananang le alkali e na le khanyetso e ntle ea alkali mme e khona ho hanela ho bola ha lintho tse phahameng tsa alkaline. E na le modulus e phahameng haholo ea elastic le ho hanyetsa tšusumetso, matla a ho tsitsa le matla a ho kobeha. E boetse e na le litšoaneleho tsa ho se chese, ho hanyetsa serame, mocheso le mongobo o hanyetsang, ho hanyetsa mapheo, ho se khonehe, polasetiki e matla le ho bōptjoa habonolo. Lithepa tsa likhopo bakeng sa konkreite e matlafalitsoeng ka khalase.
4 Tokiso ea likhoele tsa khalase
Mokhoa oa ho etsa thepa eafiber ea khalaseka kakaretso ke ho qala ho qhibilihisa lisebelisoa tse tala, ebe o etsa kalafo ea fiberizing. Haeba e tla etsoa ka sebopeho sa libolo tsa khalase kapa lithupa tsa fiberglass, kalafo ea fiberizing e ke ke ea etsoa ka kotloloho. Ho na le mekhoa e meraro ea fibrillation bakeng sa likhoele tsa khalase:
Mokhoa oa ho taka: mokhoa o ka sehloohong ke mokhoa oa ho taka oa "filament nozzle", o lateloa ke mokhoa oa ho taka molamu oa khalase le mokhoa oa ho taka oa ho qhibiliha;
Mokhoa oa Centrifugal: drum centrifugation, mohato oa centrifugation le centrifugation ea porcelain disc centrifugation;
Mokgoa wa ho foka: mokgoa wa ho foka le mokgoa wa ho letsa molomo.
Mekhoa e 'maloa e ka holimo e ka boela ea sebelisoa hammoho, e kang ho hula-ho letsa joalo-joalo. Post-processing e etsahala ka mor'a fiberizing. Ka mor'a ts'ebetso ea likhoele tsa khalase ea masela e arotsoe ka mehato e 'meli e meholo e latelang:
(1) Nakong ea tlhahiso ea likhoele tsa khalase, likhoele tsa khalase tse kopantsoeng pele ho matsoelintsoeke li lokela ho ba boholo, 'me likhoele tse khutšoane li lokela ho fafatsoa ka setlolo pele li bokelloa le ho qojoa ka masoba.
(2) Ts'ebetso e eketsehileng, ho ea ka boemo ba fiber e khutšoanyane ea khalase le e khutšoanyanekhalase ea fiber roving ho na le mehato e latelang:
①Mehato e khutšoane ea ts'ebetso ea fiber ea khalase:
②Ho sebetsana le mehato ea khalase ea fiber roving:
