Yintoni i-fiberglass?

Iifayibha zeglasi zisetyenziswa kakhulu ngenxa yokuba zisebenza kakuhle kwaye zineempawu ezintle, ikakhulu kushishino lwezinto ezidityanisiweyo. Kwasekuqaleni kwenkulungwane ye-18, abantu baseYurophu baqonda ukuba iglasi ingasontwa ibe ziifayibha zokuluka. Ibhokisi yoMlawuli waseFransi uNapoleon yayisele inamalaphu okuhombisa enziwe ngefiberglass. Iifayibha zeglasi zinefayibha kunye neefayibha ezimfutshane okanye iiflocs. Iifayibha zeglasi zihlala zisetyenziswa kwizinto ezidityanisiweyo, iimveliso zerabha, iibhanti zokuhambisa, iitarpaulins, njl. Iifayibha ezimfutshane zisetyenziswa kakhulu kwiimathi 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.

Ifayibha yeglasi iipolymers eziqinisiweyo ziqulathe udidi olukhulu lweentlobo ezahlukeneyo zeefayibha zeglasi, 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.

iipropati zefayibha yeglasi

Iimpawu eziphambili zefayibha yeglasi ziquka ezi zinto zilandelayo:

Akulula ukufunxa amanzi:Ifayibha yeglasiayingeni manzi kwaye ayifanelekanga kwiimpahla, kuba ukubila akuyi kutsalwa, nto leyo eyenza umntu oyinxibileyo azive emanzi; kuba impahla ayichaphazeleki ngamanzi, ayizukuncipha.

Ukungaguquguquki: Ngenxa yokungaguquguquki, ilaphu alinazo iindlela zokululama kwaye alinazo iintsiba. Ke ngoko, bafuna unyango lomphezulu ukuze bamelane nokushwabana.

Amandla aphezulu:Iglasi yefayibha inamandla kakhulu, phantse iqine njengeKevlar. Nangona kunjalo, xa imicu ikhuhlana, iyaphuka ize ibangele ukuba ilaphu libonakale limdaka.

Ukufakwa kwe-insulation: Ngokufutshane, i-fiberglass sisixhobo sokukhusela esibalaseleyo.

Ukuthambeka: Iifayibha ziyathambeka 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, yibhaktiriya, ngumngundo, yizinambuzane okanye yi-alkalis.

Inokuchaphazeleka:Iifayibha zeglasi zichaphazeleka yi-hydrofluoric acid kunye ne-hot phosphoric acid. Ekubeni i-fiber iyimveliso esekwe kwiglasi, ezinye ii-fiber zeglasi eziluhlaza kufuneka ziphathwe ngononophelo, njengezinto zokukhusela zasekhaya, kuba iziphelo ze-fiber zibuthathaka kwaye zinokugqobhoza ulusu, ngoko ke kufuneka unxibe iiglavu xa usebenzisa i-fiberglass.

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-fiberglass zineempawu 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.
