1. Yintoni ifibre yeglasi?
Imicu yeglasizisetyenziswa ngokubanzi ngenxa yeendleko-zokusebenza kunye neepropathi ezilungileyo, ngakumbi kwishishini le-composites. Kwangenkulungwane ye-18, abantu baseYurophu baqonda ukuba iglasi inokujijwa ibe yimicu yokulukwa. Ibhokisi yoMlawuli waseFransi uNapoleon yayisele inamalaphu okuhombisa enziwe ngawoi-fiberglass. Iifila zeglasi zinemicu yomibini kunye neentsinga ezimfutshane okanye iiflocs. Imicu yeglasi iqhele ukusetyenziswa kwizinto ezidityanisiweyo, iimveliso zerabha, amabhanti okuhambisa, iiseyile, njl.njl. Iintsinga ezimfutshane zisetyenziswa ikakhulu kwiifekethi ezingalukwanga, iiplastiki zobunjineli kunye nemathiriyeli edibeneyo.
Ifayibha yeglasi inomtsalane ngokwasemzimbeni kunye neempawu zoomatshini, ukwenza lula, kunye neendleko eziphantsi xa kuthelekiswacarbon fiberyenze ibe yimathiriyeli yokuzikhethela kwizicelo ezidityanisiweyo eziphezulu zokusebenza. Iintsinga zeglasi zenziwe ngeeoksidi zesilica. Iintsinga zeglasi zineempawu ezigqwesileyo zoomatshini ezifana nokungabi nabrittle kancinci, ukomelela okuphezulu, ukuqina okuphantsi kunye nobunzima obulula.
Iipolymers zeGlass eziqinisiweyo zibandakanya iklasi enkulu yeendlela ezahlukeneyo zeefiber zeglasi, ezinje ngeefiber ze-longitudinal, iifibers ezinqunqiweyo, iimethi ezilukiweyo, kunye neentsinga ezilukiweyo.iimethi zomcu ezinqunqiweyo, kwaye zisetyenziselwa ukuphucula iimpawu zomatshini kunye ne-tribological ye-polymer composite. Iintsinga zeglasi zinokufikelela kwimilinganiselo ephezulu, kodwa ubuqhophololo bunokubangela ukuba iintsinga zophuke ngexesha lokusetyenzwa.
1.iimpawu zefiber yeglasi
Iimpawu eziphambili zefiber yeglasi ziquka le miba ilandelayo:
Akulula ukufunxa amanzi:I-fiber ye-Glass igxotha amanzi kwaye ayifanelekanga kwiimpahla, kuba i-sweat ayiyi kuxutywa, yenza ukuba umntu onxibileyo azive emanzi; ngenxa yokuba izinto eziphathekayo azichatshazelwa ngamanzi, aziyi kuncipha
Ukungabinamdla:Ngenxa yokungabikho kwe-elasticity, ilaphu linokwelula okuncinci kunye nokubuyisela. Ngoko ke, badinga unyango olungaphezulu ukuze baxhathise imibimbi.
Amandla aphezulu:I-Fiberglass yomelele kakhulu, iphantse yomelele njenge-Kevlar. Nangona kunjalo, xa iintsinga zikhuhlana omnye komnye, ziyaphuka kwaye zibangela ukuba ilaphu libe nembonakalo ye-shaggy.
Ukhuselo:Kwifom yefiber emfutshane, i-fiberglass sisigqubuthelo esigqwesileyo.
Ukutsaleka:Iintsinga zityabeka kakuhle, zizenza zilungele amakhethini.
Ukumelana nobushushu:Iifiber zeglasi zinokumelana nokushisa okuphezulu, ziyakwazi ukumelana namaqondo okushisa ukuya kwi-315 ° C, azichaphazeli ukukhanya kwelanga, i-bleach, ibhaktheriya, isikhunta, inambuzane okanye i-alkalis.
Uchaphazeleka:Iifiber zeglasi zichatshazelwa yi-hydrofluoric acid kunye ne-hot phosphoric acid. Ekubeni i-fiber iyimveliso esekwe kwiglasi, ezinye iifiber zeglasi ezikrwada kufuneka ziphathwe ngononophelo, njengezinto zokugquma indlu, kuba iziphelo zefiber zibuthathaka kwaye zinokugqobhoza ulusu, ngoko ke iiglavu kufuneka zigqitywe xa uphethe i-fiberglass.
3. Inkqubo yokwenziwa kwefiber yeglasi
Ifiber yeglasilusinga lwentsimbi olusetyenziswa ngokubanzi njengemathiriyeli yemizi-mveliso. Ngokubanzi, izinto ezisisiseko zefiber yeglasi ziquka iiminerali ezahlukeneyo zendalo kunye neekhemikhali ezenziwe ngabantu, ezona zinto ziphambili yisanti ye-silica, i-limestone kunye nothuthu lwesoda.
Isanti ye-silica isebenza njengeglasi yangaphambili, ngelixa i-soda ash kunye ne-limestone zinceda ukuthoba ubushushu bokunyibilika. I-coefficient ephantsi yokwandiswa kwe-thermal edityaniswe ne-conductivity ephantsi ye-thermal xa kuthelekiswa ne-asbestos kunye ne-organic fibers yenza i-fiberglass ibe yinto ezinzileyo ene-dimensionally echitha ukushisa ngokukhawuleza.
Imicu yeglasiziveliswa ngokunyibilika ngokuthe ngqo, okubandakanya iinkqubo ezinjengokudibanisa, ukunyibilika, ukusonta, ukugquma, ukomiswa nokupakishwa. I-batch yimeko yokuqala yokwenziwa kweglasi, apho ubuninzi bezinto eziphathekayo buxutywe ngokucokisekileyo kwaye emva koko umxube uthunyelwa kwiziko lokunyibilika kwiqondo lokushisa eliphezulu le-1400 ° C. Eli qondo lokushisa lanele ukuguqula isanti kunye nezinye izithako zibe yimeko etyhidiweyo; iglasi enyibilikisiweyo ihambe iye kwisicoci kwaye ubushushu behle ukuya ku-1370°C.
Ngexesha lokusonta iintsinga zeglasi, iglasi etyhidiweyo iphuma ngomkhono onemingxuma ecolekileyo kakhulu. I-plate ye-liner ifudumala nge-elektroniki kwaye ukushisa kwayo kulawulwa ukugcina i-viscosity eqhubekayo. Ijethi yamanzi yasetyenziselwa ukupholisa intambo njengoko iphuma kumkhono kwiqondo lobushushu elimalunga ne-1204°C.
Umjelo okhutshiweyo weglasi etyhidiweyo utsalwa ngomatshini kwimicu enedayamitha ukusuka kwi-4 μm ukuya kwi-34 μm. Uxinzelelo lubonelelwa kusetyenziswa iwinder enesantya esiphezulu kwaye iglasi etyhidiweyo izotywe ibe yimicu. Kwinqanaba lokugqibela, iingubo zeekhemikhali ze-lubricant, i-binders kunye ne-coupling agents zifakwe kwiifilaments. I-Lubrication inceda ukukhusela i-filaments kwi-abrasion njengoko iqokelelwa kwaye ifakwe kwiiphakheji. Emva kokulinganisa, iifayili zomiswa kwi-oven; iifilaments ke zilungele ukuqhubekeka phambili zibe yimicu enqunqiweyo, iirovings okanye imisonto.
4.ukusetyenziswa kwefiber yeglasi
I-Fiberglass yimathiriyeli ye-inorganic engatshiyo kwaye igcina malunga ne-25% yamandla ayo okuqala kuma-540°C. Uninzi lweekhemikhali zinempembelelo encinci kwimicu yeglasi. I-inorganic fiberglass ayiyi kubumba okanye yonakale. Iifiber zeglasi zichatshazelwa yi-hydrofluoric acid, i-hot phosphoric acid kunye nezinto ezinamandla zealkaline.
Yimathiriyeli egqwesileyo yombane.Amalaphu eFiberglasszineepropati ezifana nokufunxa umswakama ophantsi, amandla aphezulu, ukumelana nobushushu kunye ne-dielectric ephantsi rhoqo, okwenza kube yinto efanelekileyo yokuqiniswa kweebhodi zesekethe eziprintiweyo kunye ne-insulating varnishes.
Ubungakanani bobunzima obuphezulu be-fiberglass buyenza ibe yeyona nto ibalaseleyo kwizicelo ezifuna amandla aphezulu kunye nobunzima obuncinci. Kwifom ye-textile, la mandla anokuthi abe unidirectional okanye i-bidirectional, evumela ukuguquguquka kuyilo kunye neendleko zoluhlu olubanzi lwezicelo kwimarike yeemoto, ukwakhiwa koluntu, iimpahla zemidlalo, i-aerospace, i-marine, i-electronics, iKhaya kunye namandla omoya.
Zikwasetyenziselwa ukwenziwa kwee-composites zesakhiwo, iibhodi zeesekethe eziprintiweyo kunye neemveliso ezahlukeneyo zenjongo eyodwa. Imveliso yefayibha yeglasi yonyaka imalunga ne-4.5 yezigidi zeetoni, kwaye abona bavelisi abaphambili yi-China (i-60% yesabelo semarike), i-United States kunye ne-European Union.
