Yintoni i-fiberglass?

Iifiber zeglasi zisetyenziswa ngokubanzi ngenxa yeendleko-zokusebenza kunye neempawu ezilungileyo, ikakhulu kwishishini leecomposites. Kwangenkulungwane ye-18, abantu baseYurophu baqonda ukuba iglasi inokujijwa ibe yimicu yokulukwa. Ibhokisi yoMlawuli waseFransi uNapoleon yayisele inamalaphu okuhombisa enziwe ngefiberglass. Iifila zeglasi zinemicu yomibini kunye neentsinga ezimfutshane okanye iiflocs. Iifilamenti zeglasi ziqhele ukusetyenziswa kwizinto ezidibeneyo, iimveliso zerabha, amabhanti okuhambisa, iiseyile, njl.

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.

Ifiber yeglasi iipolymers ezomeleziweyo zibandakanya iklasi enkulu yeendlela ezahlukeneyo zemicu yeglasi, njengemicu emide,iintsinga ezinqunqiweyo, iimethi ezilukiweyo, kunyeiimethi 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.

iimpawu zefiber zeglasi

Iimpawu eziphambili zefiber yeglasi ziquka le miba ilandelayo:

Akulula ukufunxa amanzi:Ifiber yeglasiigxotha amanzi kwaye ayifanelekanga kwiimpahla, kuba ukubila akuyi kuxutywa, okwenza ukuba umntu onxibileyo azive emanzi; ngenxa yokuba izinto eziphathekayo azichatshazelwa ngamanzi, aziyi kuncipha.

I-inelasticity: Ngenxa yokunqongophala kwe-elasticity, ilaphu linokwelula okuncinci kunye nokuchacha. Ngoko ke, badinga unyango olungaphezulu ukuze baxhathise imibimbi.

Amandla aphezulu:I-Fiberglass yomelele ngokugqithisileyo, iphantse yomelele njengeKevlar. Nangona kunjalo, xa iintsinga zikhuhlana omnye komnye, ziyaphuka kwaye zibangela ukuba ilaphu libe nembonakalo ye-shaggy.

I-Insulation: Kwifom emfutshane yefiber, i-fiberglass sisigqubuthelo esigqwesileyo.

Ukutsaleka: Iintsinga zithandeka kakuhle, zizenza zilungele amakhethini.

Ukumelana nokushisa: Iifiber zeglasi zinokumelana nokushisa okuphezulu, ziyakwazi ukumelana nokushisa ukuya kwi-315 ° C, azichaphazeli ukukhanya kwelanga, i-bleach, ibhaktheriya, isikhunta, inambuzane okanye i-alkalis.

Uchaphazeleka:Imicu yeglasi zichatshazelwa yi-hydrofluoric acid kunye ne-asidi ye-phosphoric eshushu. 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.

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 eFiberglass zineepropati 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.
