Iyini i-fiberglass?

Imicu yengilazi isetshenziswa kakhulu ngenxa yezindleko zayo 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 nge-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 ikakhulukazi kumata abangalukiwe, amapulasitiki 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-fiber yengilazi ama-polymers aqinisiwe ahlanganisa isigaba esikhulu sezinhlobo 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.

ingilazi fibre izakhiwo

Izici eziyinhloko ze-glass fiber zihlanganisa izici ezilandelayo:

Akulula ukumunca amanzi:I-fiber yengilaziisusa amanzi futhi ayifaneleki izingubo, ngoba izithukuthuku ngeke zidonswe, okwenza ogqokile azizwe emanzi; ngoba impahla ayithinteki emanzini, ngeke inciphe.

I-inelasticity: Ngenxa yokuntuleka kokunwebeka, indwangu inokwelula nokululama okungokwemvelo. 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.

Ukunwebeka: Imicu idonsa kahle, iwenza alungele amakhethini.

Ukumelana Nokushisa: Imicu yengilazi inokumelana nokushisa okuphezulu, ingamelana namazinga okushisa afinyelela ku-315 ° C, ayithinteki ekukhanyeni kwelanga, i-bleach, amagciwane, isikhunta, izinambuzane noma ama-alkali.

Kuyathinteka:Imicu yengilazi zithinteka yi-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.

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-Fiberglass babe nezakhiwo ezinjengokumunca umswakama ophansi, amandla aphezulu, ukumelana nokushisa kanye nokungaguquki kwe-dielectric ephansi, okwenza kube ukuqinisa okuhle kwamabhodi wesifunda aphrintiwe kanye nama-varnishes avikelayo.
