Ikirahuri cya Borosilicateni ubwoko bwikirahure kirimo boron trioxide ituma coefficient nkeya yo kwaguka kwinshi.Ibi bivuze ko itazavunika munsi yubushyuhe bukabije nkikirahure gisanzwe.Kuramba kwayo kwabaye ikirahuri cyo guhitamo ama resitora yo mu rwego rwo hejuru, laboratoire na divayi.
Icyo abantu benshi batazi nuko ibirahuri byose bitaremwe kimwe.
Ikirahuri cya Borosilike kigizwe na 15% ya trioxide ya boron, nicyo kintu cyubumaji gihindura rwose imyitwarire yikirahure kandi kikanarwanya ihungabana ryumuriro.Ibi bituma ikirahure kirwanya impinduka zikabije zubushyuhe kandi gipimwa na "Coefficient of Thermal Expansion," igipimo ikirahure cyaguka iyo gihuye nubushyuhe.Turabikesha, ikirahuri cya borosilike gifite ubushobozi bwo guhita uva muri firigo ukajya kumatanura idacitse.Kuri wewe, ibi bivuze ko ushobora gusuka amazi ashyushye mubirahuri bya borosilike niba ushaka kuvuga, icyayi cyangwa ikawa ihanamye, utitaye kumenagura cyangwa kumena ikirahure.
NIKI GUTANDUKANYA HAGATI YA BOROSILICATE GLASS NA SODA-LIME GLASS?
Ibigo byinshi bihitamo gukoresha ibirahuri bya soda-lime kubicuruzwa byibirahure kuko bihenze kandi byoroshye kuboneka.Ifite 90% yibirahuri byakozwe kwisi yose kandi ikoreshwa mubintu nkibikoresho, vase, ibirahuri byibinyobwa na Windows.Ikirahuri cya soda kirashobora guhungabana kandi ntigishobora guhindura ubushyuhe bukabije.Nibigize imiti ni silika 69% (dioxyde de silicone), soda 15% (sodium oxyde) na 9% lime (calcium oxyde).Aha niho izina rya soda-lime ikirahure.Birasa nigihe kirekire kubushyuhe busanzwe.
BOROSILICATE GLASS NUBUNTU
Coefficient ya soda-lime ikirahure nibirenze inshuro ebyiri ibirahuri bya borosilike, bivuze ko yaguka inshuro zirenze ebyiri iyo ihuye nubushyuhe kandi izacika vuba cyane.Ikirahuri cya Borosilicate gifite byinshiigipimo kinini cya dioxyde de siliconugereranije nikirahuri cya soda isanzwe (80% na 69%), bigatuma itananirwa no kuvunika.
Kubijyanye n'ubushyuhe, igipimo ntarengwa cy'ubushyuhe (itandukaniro ry'ubushyuhe bushobora kwihanganira) cy'ikirahuri cya borosilike ni 170 ° C, ni nka 340 ° Fahrenheit.Niyo mpamvu ushobora gufata ikirahuri cya borosilike (hamwe na bakeware nka Pyrex-ibindi kuri iyi hepfo) ukava mu ziko hanyuma ugakoresha amazi akonje hejuru utamennye ikirahure.
* Ikintu gishimishije, ikirahuri cya borosilike irwanya imiti, kuburyo imenyereyekubika imyanda ya kirimbuzi.Boron mu kirahure ituma idashonga, ikabuza ibikoresho byose udashaka kwinjira mu kirahure, cyangwa ubundi buryo.Ukurikije imikorere muri rusange, ikirahuri cya borosilike kiruta kure ibirahuri bisanzwe.
ESE PYREX NIMWE NA BOROSILICATE GLASS?
Niba ufite igikoni, birashoboka ko wigeze wumva izina ryirango 'Pyrex' byibuze.Ariko, ikirahuri cya borosilicate ntabwo ari kimwe na Pyrex.Igihe Pyrex yageraga ku isoko mu 1915, yabanje gukorwa mu kirahuri cya borosilike.Yahimbwe mu mpera za 1800 n’umudage ukora ibirahuri Otto Schott, yamenyesheje isi ikirahuri cya borosilicate mu 1893 ku izina rya Duran.Mu 1915, Corning Glass Works yazanye ku isoko ryo muri Amerika ku izina rya Pyrex.Kuva icyo gihe, ibirahuri bya borosilike na Pyrex byakoreshejwe mu buryo bumwe mu rurimi ruvuga Icyongereza.Kubera ko ibirahuri bya Pyrex byabanje gukorwa mubirahuri bya borosilike, byashoboye kwihanganira ubushyuhe bukabije bituma biba igikoni cyiza kandi gikorana n’itanura, bikagira uruhare runini mu myaka yashize.
Uyu munsi, ntabwo Pyrex yose ikozwe mubirahuri bya borosilike.Imyaka mike ishize, Corningbahinduye ibikoresho mubicuruzwa byabokuva ikirahuri cya borosilike kugeza ikirahuri cya soda-lime, kuko cyakoreshaga amafaranga menshi.Ntidushobora rero kumenya neza mubyukuri borosilicate nibitari mumurongo wibicuruzwa bya Pyrex.
NIKI GLASS ZA BOROSILICATE ZIKORESHWA?
Kubera uburebure bwayo no kurwanya ihinduka ry’imiti, ikirahuri cya borosilike cyakoreshejwe muri laboratoire ya chimie no mu nganda, ndetse no mu gikoni ndetse n’ibirahure bya divayi bihebuje.Kubera ubuziranenge bwayo, akenshi usanga igiciro kiri hejuru yikirahure cya soda.
NAKWIYE KUBONA AMAFOTO YA BOROSILIQUE?EREGA AMAFARANGA YANJYE?
Iterambere rikomeye rirashobora gukorwa hamwe nimpinduka nto kumico yacu ya buri munsi.Muri iki gihe, kugura amacupa yamazi ya pulasitike birasobanutse gusa urebye ubundi buryo buboneka.Niba utekereza kugura icupa ryamazi yongeye gukoreshwa, iyo niyo ntambwe yambere yambere muguhindura imibereho myiza.Biroroshye gutuza ibicuruzwa bisanzwe bidahenze kandi bigakora akazi, ariko ibyo nibitekerezo bitari byo niba ushaka kuzamura ubuzima bwawe bwite no guhindura imibereho myiza.Filozofiya yacu ni nziza kurenza ubwinshi, kandi kugura ibicuruzwa biramba ni amafaranga yakoreshejwe neza.Dore zimwe mu nyungu zo gushora mumacupa yikirahure ya borosilicate.
Nibyiza kuri wewe.Kubera ko ibirahuri bya borosilike birwanya imiti no kwangirika kwa aside, ntukeneye guhangayikishwa nibintu byinjira mumazi yawe.Buri gihe ni byiza kunywa.Urashobora kubishyira mumasabune, ukabishyira muri microwave, ukabika kubika amazi ashyushye cyangwa ukayirekera izuba.Ntuzakenera guhangayikishwa nicupa rishyuha no kurekura uburozi bwangiza mumazi urimo unywa, ikintu gikunze kugaragara mumacupa yamazi ya plastike cyangwa ibyuma bidahenze cyane.
Nibyiza kubidukikije.Amacupa yamazi ya plastike ateye ubwoba kubidukikije.Byakozwe muri peteroli, kandi hafi ya byose birangirira mumyanda, ikiyaga cyangwa inyanja.9% gusa bya plastiki zose zongera gukoreshwa.Ndetse no muri icyo gihe, inshuro nyinshi inzira yo kumena no gukoresha plastike isiga ikirenge kiremereye.Kubera ko ikirahuri cya borosilike gikozwe mubikoresho bisanzwe byoroshye kuboneka kuruta amavuta, ingaruka kubidukikije nazo ni nto.Niba ukoresheje ubwitonzi, ibirahuri bya borosilike bizaramba mubuzima bwawe bwose.
Bituma ibintu biryoha neza.Waba warigeze unywa mumacupa yicyuma ya plastike cyangwa idafite umwanda hanyuma ukaryoshya uburyohe bwa plastiki cyangwa ibyuma unywa?Ibi bibaho kuko mubyukuri byinjira mumazi yawe kubera gukomera kwa plastiki nicyuma.Ibi byombi byangiza ubuzima bwawe kandi ntibishimishije.Iyo ukoresheje ikirahuri cya borosilike amazi yimbere akomeza kuba meza, kandi kubera ko ikirahuri cya borosilike gifite imbaraga nke, bituma ibinyobwa byawe bitanduza.
ICYUBAHIRO SI ICYIZA GUSA
Mugihe itandukaniro ritandukanye rishobora kugaragara, ntabwo arimwe.Ikirahuri cya Borosilicate nikintu gikomeye kizamurwa mubirahuri gakondo, kandi itandukaniro rirashobora kugira ingaruka zikomeye kubuzima bwawe bwite no kubidukikije iyo byiyongereye mugihe.
