Ikirahuri cya Borosuilicate kiruta ikirahuri gisanzwe?

Ikirahure cya Borosuilicate cyita ku busumbabunze hejuru yikirahure gisanzwe mugupakira no kubindi bikorwa byinshi. Ariko nibyiza rwose?

Muri iki kiganiro, twirukana mubice, ibiranga, ibyiza hejuru yikirahure gisanzwe, nuburyo butandukanye bwibirahure byabitswe kugirango bisobanuke kuri iki kibazo.

Ikirahure kirimo ikirahuri ki?

Ikirahure cyabitswe gikozwe muri 2 byingenzi: Silica na Boron. Igipimo cyo gushonga cya Silica ni kinini cyane (1730 ° C), kugirango ibi bikoresho bitunganizwe ku bushyuhe bwo hasi bityo uzigame imbaraga, ibindi bice byitwa Fluxes byongeyeho. Nanone, ibindi bishanga (oxides, alkaline, alumina, na alkaline oxides) yongewe kugirango ikomeze ikirahure, kikamuha imitungo myiza.

Ibyiza byikirahure cyamasamyo
cyinshi zo kurwanya imiti myiza: umutekano mwinshi kandi urambye mubidukikije.
Kurwanya ubushyuhe bwinshi: Kurwanya neza kubushyuhe bwa Trarmal hamwe nubushyuhe, hamwe no kwaguka hasi.
Imbaraga nziza zamabuye: kwambara cyane- no guterwa no gutesha agaciro, hamwe n'imbaraga zizewe hamwe nubushobozi bwo kwihanganira bisaba imitwaro ya mashini.
Gufungura mu mucyo hejuru: Gushiraho neza no kugoreka-kugoreka-kugoreka kugoreka ku buryo bukabije.
Ubwoko bwibirahuri birarahuri

ikirahure biza muburyo butandukanye bitewe nibirimo boron oxide, bigira ingaruka kumitungo yayo. Ubu bwoko burimo:

ikirahure cyamasasu gike: Ubu bwoko burimo ijanisha rito rya Boron okiside, mubisanzwe kuva kuri 5% kugeza 10%. Itanga uburyo bworoshye bwo guhagarika umutima kandi bikunze gukoreshwa mubintu byo murugo nka guteka no kunywa.
Ikirahure cya Borosuilicate: Hamwe nibirimo boron oxide kuva kuri 10% kugeza kuri 13%, ibirahuri biciriritse bitanga imbaraga zubushyuhe bworoshye ugereranije na blezuire nkeya. Irasanga ibyifuzo mubikoresho bya laboratoire nimiterere yinganda aho kuramba hejuru.
Ikirahure kinini cya Borosulicate: Ikirahure cya Borosuilicate kirimo ijanisha ryinshi rya Boron okiside, mubisanzwe irenga 13%. Ubu bwoko bwirata kurwanya ubushyuhe bukabije bwo guhagarika umutima no kuramba bikabije, bigatuma bikwiranye no gusaba ibyifuzo nkibirabura bya laboratoire hamwe na optics.
Umwanzuro

Mugusoza, Ikirahure cya Borosuilicate gitanga ibyiza byinshi hejuru yikirahure, harimo guhagarika umutima no kurwanya imiti, ndetse no kurambagiza. Mugihe ikirahure cyo kuraramo gishobora kuza ku giciro cyo hejuru, imikorere idasanzwe kandi kuramba akenshi byerekana ishoramari, cyane cyane mu gupakira.
