1. Yintoni ifayibha yeglasi?
Iifayibha zeglasizisetyenziswa kakhulu ngenxa yokuba zisebenza kakuhle kwiindleko zazo kunye neempawu zazo ezilungileyo, ikakhulu kwishishini lee-composites. Kwasekuqaleni kwenkulungwane ye-18, abantu baseYurophu baqonda ukuba iglasi ingasontwa ibe yimicu yokuluka. Ibhokisi yoMlawuli waseFransi uNapoleon yayisele ineempahla zokuhombisa ezenziwei-fiberglassIifayibha zeglasi zinemicu kunye neefayibha ezimfutshane okanye iiflocs. Iifayibha zeglasi zihlala zisetyenziswa kwizinto ezidityanisiweyo, iimveliso zerabha, iibhanti zokuhambisa, iitarpaulins, njl. Iifayibha ezimfutshane zisetyenziswa kakhulu kwiifelts ezingalukwanga, iiplastiki zobunjineli kunye nezinto ezidityanisiweyo.
Iimpawu ezintle zomzimba neze-mechanical ze-glass fiber, kulula ukwenziwa, kunye nexabiso eliphantsi xa kuthelekiswaifayibha yekhabhoniyenze ibe yinto ekhethwayo kwizicelo ze-composite ezisebenza kakuhle. Iifayibha zeglasi zenziwe ngee-oxides ze-silica. Iifayibha zeglasi zineempawu ezintle kakhulu zokwenza izinto ezifana nokuba azikhuli kakhulu, azinamandla aphezulu, aziqini kakhulu kwaye zinobunzima obuphantsi.
Iipolymers eziqinisiweyo zefayibha yeglasi ziqulathe udidi olukhulu lweentlobo ezahlukeneyo zefayibha yeglasi, ezifana neefayibha ezinde, iifayibha ezinqunqiweyo, iimathi ezilukiweyo, kunyeiimathi ezinqunqiweyo zemicu, kwaye zisetyenziselwa ukuphucula iipropati zoomatshini kunye neze-tribological zee-polymer composites. Iifayibha zeglasi zinokufikelela kwi-aspect ratios ephezulu yokuqala, kodwa ukubhitya kunokubangela ukuba iifayibha ziqhekeke ngexesha lokucubungula.
1. iimpawu zefayibha yeglasi
Iimpawu eziphambili zefayibha yeglasi ziquka ezi zinto zilandelayo:
Akulula ukufunxa amanzi:Ifayibha yeglasi iyagxotha amanzi kwaye ayifanelekanga kwiimpahla, kuba ukubila akuyi kutsalwa, okwenza umntu onxibe impahla azive emanzi; kuba impahla ayichaphazeleki ngamanzi, ayizukuncipha
Ukungaguquguquki:Ngenxa yokungaguquguquki, ilaphu alinazo iindlela zokululama kwaye alinazo iintsiba. Ke ngoko, kufuneka lilungiswe ukuze likwazi ukumelana nokushwabana.
Amandla aphezulu:I-fiberglass inamandla kakhulu, phantse iqine njengeKevlar. Nangona kunjalo, xa iifayibha zikhuhlana, ziyaphuka kwaye zibangele ukuba ilaphu libonakale limdaka.
Ubushushu:Ngamafutshane, i-fiberglass sisixhobo sokukhusela ubushushu esibalaseleyo.
Ukungakwazi ukujika:Iifayibha zigutyungelwa kakuhle, nto leyo eyenza ukuba zilungele amakhethini.
Ukumelana nobushushu:Iifayibha zeglasi zinokumelana nobushushu obuphezulu, ziyakwazi ukumelana nobushushu obufikelela kwi-315°C, azichaphazeleki kukukhanya kwelanga, yi-bleach, yibhaktheriya, yi-mold, yizinambuzane okanye yi-alkalis.
Inokuchaphazeleka:Iifayibha zeglasi zichaphazeleka yi-hydrofluoric acid kunye ne-hot phosphoric acid. Ekubeni ifayibha iyimveliso esekwe kwiglasi, ezinye iifayibha zeglasi eziluhlaza kufuneka ziphathwe ngononophelo, njengezinto zokukhusela zasekhaya, kuba iziphelo zefayibha zibuthathaka kwaye zinokugqobhoza ulusu, ngoko ke kufuneka unxibe iiglavu xa usebenzisa i-fiberglass.
3. Inkqubo yokuvelisa ifayibha yeglasi
Ifayibha yeglasiyifayibha engeyiyo isinyithi esetyenziswa kakhulu ngoku njengezinto zoshishino. Ngokubanzi, izinto ezisisiseko zefayibha yeglasi ziquka iiminerali ezahlukeneyo zendalo kunye neekhemikhali ezenziwe ngumntu, izinto eziphambili yisanti yesilika, ilimestone kunye nothuthu lwesoda.
Isanti yesilika isebenza njengeglasi, ngelixa i-soda ash kunye ne-limestone zinceda ekunciphiseni ubushushu obunyibilikayo. I-coefficient ephantsi yokwandiswa kobushushu kunye nokuqhuba kobushushu obuphantsi xa kuthelekiswa ne-asbestos kunye neefayibha ze-organic kwenza i-fiberglass ibe yinto ezinzileyo ngokwemilinganiselo ephelisa ubushushu ngokukhawuleza.
Iifayibha zeglasiZiveliswa ngokunyibilika ngokuthe ngqo, okubandakanya iinkqubo ezifana nokudibanisa, ukunyibilika, ukujikelezisa, ukugquma, ukomisa, kunye nokupakishwa. Ibhetshi yimeko yokuqala yokwenziwa kweglasi, apho ubungakanani bezinto ezisetyenzisiweyo buxutywa kakuhle kwaye emva koko umxube uthunyelwa kwisithando ukuze unyibilike kubushushu obuphezulu be-1400°C. Olu bushushu banele ukuguqula isanti kunye nezinye izithako zibe yimeko enyibilikisiweyo; iglasi enyibilikisiweyo emva koko ingena kwi-refiner kwaye ubushushu behla buye kwi-1370°C.
Ngexesha lokujikeleziswa kwemicu yeglasi, iglasi enyibilikisiweyo iphuma ngesingxobo esineembobo ezincinci kakhulu. Ipleyiti ye-liner ifudunyezwa ngombane kwaye ubushushu bayo bulawulwa ukuze kugcinwe i-viscosity engaguqukiyo. Kusetyenziswe i-water jet ukupholisa i-filament njengoko iphuma kwisingxobo kubushushu obumalunga ne-1204°C.
Umjelo weglasi enyibilikisiweyo okhutshiweyo utsalwa ngoomatshini ube yi-filaments enobubanzi obuqala kwi-4 μm ukuya kwi-34 μm. Uxinzelelo lubonelelwa kusetyenziswa isixhobo sokujikelezisa esikhawulezayo kwaye iglasi enyibilikisiweyo itsalwa ibe yi-filaments. Kwinqanaba lokugqibela, kufakwa iikhemikhali zokugquma, izibopheleli kunye nee-coupling agents kwi-filaments. Ukuthambisa kunceda ukukhusela i-filaments ekukrweleni njengoko iqokelelwa kwaye ibotshelelwe kwiipakethe. Emva kokulinganisa, i-filaments yomiswa kwi-oven; i-filaments emva koko ilungele ukucutshungulwa ngakumbi ibe yi-filaments ezinqunqiweyo, ii-rovings okanye iintambo.
4.ukusetyenziswa kwefayibha yeglasi
Iglasi yefayibha yinto engaphiliyo engatshiyo kwaye igcina malunga ne-25% yamandla ayo okuqala kwi-540°C. Uninzi lweekhemikhali alunampembelelo ingako kwimicu yeglasi. I-fiberglass engaphiliyo ayizukubola okanye yonakale. Imicu yeglasi ichatshazelwa yi-hydrofluoric acid, i-hot phosphoric acid kunye nezinto ezinamandla ze-alkaline.
Yinto ebalaseleyo yokukhusela umbane.Amalaphu e-fiberglasszineempawu ezifana nokufunxwa komswakama okuncinci, amandla aphezulu, ukumelana nobushushu kunye nokuqina okuncinci kwe-dielectric, nto leyo eyenza ukuba zibe zizinto ezifanelekileyo zokuqinisa iibhodi zesekethe eziprintiweyo kunye neevarnish zokukhusela.
Umlinganiselo ophezulu wamandla ukuya kobunzima be-fiberglass wenza ukuba ibe yinto efanelekileyo kwizicelo ezifuna amandla aphezulu kunye nobunzima obuncinci. Kwimo yelaphu, la mandla anokuba ngawamacala omabini okanye abe ngamacala amabini, okuvumela ukuguquguquka kuyilo kunye neendleko kwiintlobo ngeentlobo zezicelo kwimarike yeemoto, ulwakhiwo lwezakhiwo, iimpahla zemidlalo, i-aerospace, i-marine, i-electronics, i-Home kunye namandla omoya.
Zikwasetyenziswa ekwenziweni kwezinto ezidityanisiweyo zokwakha, iibhodi zeesekethe eziprintiweyo kunye neemveliso ezahlukeneyo zeenjongo ezikhethekileyo. Imveliso yefayibha yeglasi yonyaka ehlabathini imalunga ne-4.5 yezigidi zeetoni, kwaye abavelisi abaphambili yiTshayina (isabelo semarike esingama-60%), i-United States kunye ne-European Union.
