1. Iyini i-glass fiber?
Imicu yengilazizisetshenziswa kabanzi ngenxa yokungabizi kwazo kanye nezakhiwo ezinhle, ikakhulukazi embonini yezinhlanganisela. Emuva ekhulwini le-18, abantu baseYurophu baqaphela ukuthi ingilazi ingaphothwa ibe imicu yokulukwa. Ibhokisi loMbusi waseFrance uNapoleon lase linezindwangu zokuhlobisa ezenziwe ngazoi-fiberglass. Imicu yengilazi inakho kokubili imicu kanye nemicu emifushane noma ama-flocs. Imicu yengilazi ivamise ukusetshenziswa ezintweni eziyinhlanganisela, emikhiqizweni yenjoloba, amabhande okuthutha, oseyili, njll. Imicu emifushane isetshenziswa kakhulu ezintweni ezingalukiwe, kumapulasitiki obunjiniyela nezinto eziyinhlanganisela.
Izakhiwo ezikhangayo ze-Glass fiber ezingokomzimba nezomshini, ukwenziwa lula, nezindleko eziphansi uma kuqhathaniswai-carbon fiberyenze ibe yimpahla yokuzikhethela yezinhlelo zokusebenza eziyinhlanganisela esebenza kakhulu. Imicu yengilazi yenziwe ngama-oxide e-silica. Amafayibha engilazi anezakhiwo ezinhle kakhulu zemishini njengokungabi nabrittle kancane, amandla aphezulu, ukuqina okuphansi kanye nesisindo esincane.
I-Glass fiber reinforced polymers iqukethe iklasi elikhulu lezinhlobo ezahlukene zemicu yengilazi, njengemicu ye-longitudinal, imicu eqoshiwe, amacansi abelukiwe, kanyeamacansi ama-strand aqoshiwe, futhi asetshenziselwa ukuthuthukisa izakhiwo zemishini kanye ne-tribological yezinhlanganisela ze-polymer. Amafayibha engilazi angafinyelela izilinganiso eziphezulu ze-aspect ratio, kodwa ukuqina kungabangela amafayibha aphuke ngesikhathi sokucutshungulwa.
1.izici ze-glass fiber
Izici eziyinhloko ze-glass fiber zihlanganisa izici ezilandelayo:
Akulula ukumunca amanzi:I-Glass fiber inqamule amanzi futhi ayifaneleki izingubo, ngoba umjuluko ngeke udonswe, okwenza lowo ogqokile azizwe emanzi; ngoba impahla ayithinteki emanzini, ngeke inciphe
I-Inelasticity:Ngenxa yokuntuleka kwe-elasticity, indwangu inokwelula okuncane okungokwemvelo nokululama. Ngakho-ke, badinga ukwelashwa okungaphezulu ukuze bamelane nemibimbi.
Amandla Aphezulu:I-Fiberglass iqine ngokwedlulele, icishe iqine njenge-Kevlar. Nokho, lapho imicu ikhuhlana yodwa, iyaphuka futhi ibangele ukuthi indwangu ibonakale ishaggy.
I-Insulation:Ngefomu elifushane le-fiber, i-fiberglass iyisivikeli esihle kakhulu.
I-drapability:Imicu idonsa kahle, ibenze ilungele amakhethini.
Ukumelana Nokushisa:Imicu yengilazi inokumelana nokushisa okuphezulu, ingamelana namazinga okushisa afinyelela ku-315 ° C, ayithinteki ukukhanya kwelanga, i-bleach, amabhaktheriya, isikhunta, izinambuzane noma ama-alkali.
Kuyathinteka:Imicu yengilazi ithintwa i-hydrofluoric acid ne-hot phosphoric acid. Njengoba i-fiber ingumkhiqizo osuselwe engilazini, eminye imicu yengilazi eluhlaza kufanele iphathwe ngokucophelela, njengezinto zokufakwa endlini, ngoba iziphetho ze-fiber zintekenteke futhi zingabhoboza isikhumba, ngakho-ke amagilavu kufanele agqoke lapho ubamba i-fiberglass.
3. Inqubo yokukhiqiza ye-glass fiber
I-fiber yengilaziiyifayibha engeyona eyensimbi okwamanje esetshenziswa kabanzi njengempahla yezimboni. Ngokuvamile, izinto eziyisisekelo zokusetshenziswa kwe-glass fiber zihlanganisa amaminerali emvelo ahlukahlukene namakhemikhali enziwe umuntu, izingxenye eziyinhloko isihlabathi se-silica, i-limestone kanye nomlotha we-soda.
Isihlabathi se-silica sisebenza njengengilazi yangaphambili, kuyilapho i-soda ash kanye ne-limestone kusiza ukwehlisa izinga lokushisa elincibilikayo. I-coefficient ephansi yokunwetshwa kwe-thermal ehlanganiswe ne-thermal conductivity ephansi uma kuqhathaniswa ne-asbestos nama-organic fibers kwenza i-fiberglass ibe into ezinzile enobukhulu ehlakaza ukushisa ngokushesha.
Imicu yengilaziakhiqizwa ukuncibilika okuqondile, okubandakanya izinqubo ezifana nokuhlanganisa, ukuncibilika, ukuphotha, ukunamathela, ukomisa, nokupakisha. Iqoqo yisimo sokuqala sokukhiqiza ingilazi, lapho izinto eziningi zixutshwe kahle bese ingxube ithunyelwa esithandweni ukuze incibilike ekushiseni okuphezulu kuka-1400 ° C. Lokhu kushisa kwanele ukuguqula isihlabathi nezinye izithako zibe isimo esincibilikisiwe; ingilazi encibilikisiwe ibe isigeleza iye esicocini bese izinga lokushisa lehla libe ngu-1370°C.
Ngesikhathi sokuphothwa kwemicu yengilazi, ingilazi encibilikisiwe iphuma ngomkhono onezimbobo ezinhle kakhulu. Ipuleti liner lishiswa nge-elekthronikhi futhi izinga lokushisa layo lilawulwa ukuze kugcinwe i-viscosity engaguquki. Indiza yamanzi yasetshenziswa ukupholisa umucu njengoba iphuma emkhonweni ezingeni lokushisa elicishe libe ngu-1204°C.
Umfudlana okhishiwe wengilazi encibilikisiwe udonswa ngomshini ube imicu enobubanzi obusuka ku-4 μm kuya ku-34 μm. Ukuqina kunikezwa kusetshenziswa iwinda enesivinini esikhulu futhi ingilazi encibilikisiwe idwetshwa ibe imicu. Esigabeni sokugcina, ukumbozwa kwamakhemikhali kwamafutha, ama-binders nama-coupling agents asetshenziselwa imicu. Ukugcotshwa kusiza ukuvikela imicu ekuhuzukeni njengoba iqoqwa bese ifakwa emaphaketheni. Ngemva kokulinganisa, imicu yomiswa kuhhavini; imicu ibe isilungele ukuqhubeka nokucutshungulwa ibe imicu eqoshiwe, ama-rovings noma imicu.
4.ukusetshenziswa kwe-glass fiber
I-Fiberglass iyinto engashisi futhi egcina cishe u-25% wamandla ayo okuqala ku-540°C. Amakhemikhali amaningi anomphumela omncane emicu yengilazi. I-Inorganic fiberglass ngeke ibumbe noma yonakale. Imicu yengilazi ithintwa i-hydrofluoric acid, i-hot phosphoric acid nezinto ezinamandla ze-alkaline.
Kuyinto enhle kakhulu kagesi insulating material.Izindwangu ze-Fiberglassbabe nezakhiwo ezinjengokumunca umswakama ophansi, amandla aphezulu, ukumelana nokushisa kanye nokungaguquki kwe-dielectric ephansi, okwenza kube ukuqinisa okuhle kwamabhodi wesifunda aphrintiwe kanye nama-varnishes avikelayo.
Isilinganiso esiphakeme samandla nesisindo se-fiberglass siyenza into enhle kakhulu yezinhlelo zokusebenza ezidinga amandla aphezulu nesisindo esincane. Ngefomu lendwangu, lawa mandla angaba unidirectional noma bidirectional, okuvumela ukuguquguquka ekuklanyweni kanye nezindleko zezinhlelo eziningi zokusebenza emakethe yezimoto, ukwakhiwa komphakathi, izimpahla zezemidlalo, i-aerospace, i-marine, i-electronics, amandla asekhaya nawomoya.
Zibuye zisetshenziswe ekwenzeni izinhlanganisela zesakhiwo, amabhodi esekethe aphrintiwe kanye nemikhiqizo ehlukahlukene yenhloso ekhethekile. Ukukhiqizwa kwefayibha yengilazi minyaka yonke emhlabeni kungamathani ayizigidi ezi-4.5, futhi abakhiqizi abakhulu yiShayina (isabelo semakethe esingamaphesenti angama-60), i-United States kanye ne-European Union.
