Izinhlobonhlobo zemikhiqizo ye-fiberglass
I-Fiberglass iyinto enhle kakhulu ye-inorganic non-metallic.I-fiber yengilaziiwuhlobo lwensimbi yemvelo engeyona eyensimbi efana ne-leucolite, i-pyrophyllite, i-kaolin, isihlabathi se-quartz, i-limestone, njll. / 20-1/5 izinwele.
Kunezinhlobo eziningi ze-glass fiber, ezifanele izimo ezahlukene.I-Glass fiber ingahlukaniswa ngezinhlobo ezahlukene ngokuya ngokwakhiwa, okungeyona i-alkali, i-alkali ephakathi, i-alkali ephezulu, amandla aphezulu, i-boron-free kanye ne-non-alkali, njll. Ukusebenza kuhlukile, futhi kuyasetshenziswa. emikhakheni ehlukene ngokuya nezici zayo zokusebenza.Isibonelo, imicu yengilazi enokuqukethwe kwe-alkali metal oxide engaphansi kuka-0.8%.imicu yengilazi engena-alkali, ezine-insulation kagesi ezinhle kanye nezakhiwo zemishini, kodwa ukumelana ne-asidi ephansi, ngakho-ke zisetshenziswa kakhulu ezigcawini ezidinga ukufakwa kukagesi noma ku-FRP;Okuqukethwe okungu-11.9% -16.4% kungokwe-medium-alkali glass fiber, enokumelana ne-asidi eqinile kodwa ukusebenza kabi kukagesi, futhi amandla ayo okusebenza aphansi kunalawo e-non-alkali glass fiber.Isetshenziswa phesheya ukuze kuqiniswe izinto zokufulela i-asphalt ezinezidingo zamandla emishini ephansi;I-fiber yengilazi enamandla amakhulu iqukethe inani elithile le-zirconia, elinezici zamandla aphezulu, ukukhishwa okuphansi kanye nezindleko eziphakeme, ngakho-ke isetshenziswa kakhulu emikhiqizweni yezempi;ngaphezu kwalokho, i-high-alkali fiber inokusebenza okungalungile futhi isusiwe ngokuyisisekelo.
I-Fiberglass Composite
I-Glass fiber ingabuye ihlanganiswe nezinye izinto zokwakha i-glass fiber composite materials, okuyi-FRP ewumkhiqizo oyinhloko.I-Glass fiber ingahlanganiswa ne-resin ukwenza i-glass fibre reinforced plastic (FRP), noma yengeze itiyela ukwenza itiyela eliqiniswe yi-glass fibre.Ngenxa yezinhlobonhlobo ezinkulu zezinto ezingahlanganiswa, okwamanje akukho ukuhlukaniswa okucacile kwezinto ze-glass fiber composite.Ngokwemininingwane ye-Qianzhan Industry Research Institute, i-FRP ithatha cishe u-75% wemakethe yezinto ezihlanganisiwe zengilazi nemikhiqizo, ethatha isikhundla esiphezulu.Ngakho-ke, sithatha i-FRP njengesibonelo ukuze sihlaziye izinzuzo zokusebenza zezinhlanganisela ze-glass fiber.
I-FRP ingenye impahla esebenza kahle kakhulu.I-FRP iyinhlanganisela yezinto ezine-resin yokwenziwa njenge-matrix ne-glass fiber kanyeimikhiqizo ye-fiberglass(umata, indwangu, ibhande, njll.) njengento yokuqinisa.I-FRP ithola igama layo kusukela ekubukekeni kwayo okufana nengilazi namandla aqinile afana nensimbi.Uma kuqhathaniswa nensimbi evamile ekwakhiweni, ukuminyana kwensimbi yi-7.85 × 103kg/m3, kanti ukuminyana kwe-FRP yi-1.9 × 103kg/m3, elula kunensimbi, namandla ayo athile kanye nokumelana nokugqwala kudlula kude insimbi;uma kuqhathaniswa ne-aluminium alloy , i-thermal conductivity ye-aluminium alloy ingu-203.5W/m.℃, kanye ne-thermal conductivity ye-FRP ngu-0.3W/m.℃.Ukusebenza kokushisa okushisayo kwe-FRP kungcono, futhi impilo yesevisi ye-FRP iminyaka engu-50, okuphindwe kabili kune-aluminium alloy.Ngenxa yokusebenza kwayo okuhle kakhulu okubanzi, i-FRP, esikhundleni sezinto ezisetshenziswayo zendabuko, isetshenziswa kakhulu ekwakhiweni, ojantshi bezitimela, emkhathini, kuma-yacht berthing nakwezinye izimboni.
Iketango lemboni ye-fiber yengilazi
Izinto zokusetshenziswa ezikhuphuka nomfula ze-glass fibre kulula ukuzithola, futhi ukusetshenziswa komfula kubanzi uma kuqhathaniswa.Izinto ezisetshenziswayo zokukhiqizwa kwefiber yengilazi ngokuyinhloko ziyizinto zokusetshenziswa zamaminerali nezinto zokusetshenziswa zamakhemikhali, okuhlanganisa i-pyrophyllite, i-kaolin, isihlabathi se-quartz, i-limestone, njll., okungamaminerali anezinqolobane ezinkulu e-China, futhi kunzima ukuyithola;amandla asetshenziswayo ikakhulukazi ugesi negesi yemvelo;izinhlelo zokusebenza ezansi nomfula Ibanzi uma kuqhathaniswa, ikakhulukazi kubandakanya izinto zokwakha, ezokuthutha, izinto zikagesi zikagesi, okokusebenza kwezimboni, amandla kanye nokuvikelwa kwemvelo kanye neminye imikhakha.
I-Glass fibreisidingo semakethe
Ngokombono omkhulu, kulindeleke ukuthi isilinganiso sezinga lokukhula kwesidingo se-glass fiber yezwe lami nezinga lokukhula kwe-GDP lizohlala lisezingeni eliphezulu esikhathini esifushane.Kulinganiselwa ukuthi ukusetshenziswa kwe-fiber yengilazi yezwe lami eminyakeni engu-22/23 kuzoba amathani ayizigidi ezingu-5.34 kanye namathani ayizigidi ezingu-6, okuwukukhuphuka ngo-13.2% no-12.5% ngokulandelana.
Uma kucatshangelwa ukusetshenziswa okubanzi kwe-glass fibre, izinkomba ze-macroeconomic yasekhaya zisenokubaluleka okuyisiqondiso ekwahluleleni isidingo sefayibha yengilazi yasekhaya.Uma kubhekwa: 1) ukusetshenziswa konyaka komuntu ngamunye kwe-glass fiber kuphansi kakhulu kunamazwe athuthukile;2) izinga lokungena kwefayibha yengilazi emikhakheni eyinhloko yokusetshenziswa kwefayibha yengilazi, njengokwakha kanye nemoto, liphansi kakhulu kunelamazwe athuthukile, futhi njengento entsha Eqondiswa ukugqugquzelwa kwenqubomgomo, sikholelwa ukuthi isilinganiso sezwe lami izinga lokukhula kwesidingo se-glass fibre ukuze izinga lokukhula kwe-GDP lizohlala lisezingeni eliphakeme kakhulu esikhathini esifushane, futhi kulindeleke ukuthi lisondele kancane kancane emakethe evuthiwe esikhathini esimaphakathi nesikhathi eside.
Kulindeleke ukuthi isilinganiso sezinga lokukhula kwesidingo se-glass fiber yezwe lami nezinga lokukhula kwe-GDP lizohlala lisezingeni eliphakeme kakhulu esikhathini esifushane.Ngaphansi kokucatshangwa kwesimo esingathathi hlangothi, kulinganiselwa ukuthi isilinganiso sezinga lokukhula kwesidingo se-fiber yengilazi nezinga lokukhula kwe-GDP eminyakeni engama-22/23 lizoba ngu-2.4 no-2.4 ngokulandelanayo, elihambisana ne-glass fiber.Izinga lokukhula kwesidingo se-fiber lalingu-13.2% no-12.5% ngokulandelana, kanti ukusetshenziswa kwe-fiber yengilazi kwakungamathani ayizigidi ezingu-5.34 kanye nezigidi ezingu-6 ngokulandelana.
