Uruhare rwibiryo byo mu rwego rwa Titanium Dioxyde de Candy
Amapaki
Urwego rwibiryo rwa titanium dioxydeni imyunyu ngugu isanzwe ikoreshwa nkibintu byera kandi byera mubiribwa bitandukanye, harimo na bombo. Ninyongera kandi yizewe yemewe gukoreshwa mubiribwa ninzego zishinzwe kugenzura isi yose, harimo n’ikigo cy’Amerika gishinzwe ibiryo n’ibiyobyabwenge (FDA) n’ikigo cy’ubumwe bw’ibihugu by’Uburayi gishinzwe umutekano (EFSA).
Mu gukora bombo, ibiryo bya titanium dioxyde ikoreshwa mugukora amabara meza, adasobanutse yongerera imbaraga ibicuruzwa byanyuma. Ifite akamaro cyane mugushikira amabara meza kandi ahoraho muri bombo, bigatuma iba ikintu cyingenzi kubatekera no gukora bombo.
Imwe mu miterere yingenzi yibiribwa bya titanium dioxyde nubushobozi bwayo bwo kwerekana no gusasa urumuri, rufasha kurema ubuso bworoshye, burabagirana kuribombo. Ibi ni ingenzi cyane cyane kuri bombo ya shell-shell, nka shokora isize hamwe na bombo zometse kuri bombo, aho isura ya coating ari ahantu hanini ho kugurisha.
Usibye ubwiza bwayo, dioxyde de titanium yo mu rwego rwo hejuru nayo igira uruhare runini mugutwikira bombo. Ifasha kunoza imiterere hamwe numunwa wikibiriti, ikayiha guhuza neza no kwisiga byongera uburambe muri rusange. Ibi ni ingenzi cyane cyane mubyokurya bigenewe kwiyumvisha ibyiyumvo, kuko imiterere yikibiriti irashobora guhindura cyane imyumvire yibicuruzwa.
Nubwo dioxyde ya titanium ikoreshwa cyane mu nganda z’ibiribwa, haracyari impaka zishingiye ku mutekano wadioxyde ya titanium mu biryo. Ubushakashatsi bumwe bwagaragaje impungenge z’ingaruka z’ubuzima ziterwa no kunywa titanium dioxyde de nanoparticles, ari utuntu duto duto duto dushobora kuba dufite imiterere itandukanye n’ibice binini.
Icyakora, birakwiye ko tumenya ko dioxyde de titanium yo mu rwego rwo hejuru igengwa n’inzego zishinzwe kugenzura ibiryo. Imikoreshereze y’ibiribwa byo mu rwego rwa titanium dioxyde mu bubiko bwa bombo iragenzurwa cyane kugira ngo yubahirize ibipimo by’umutekano kandi ntibibangamire abaguzi.
Mu gusoza, ibiryo bya titanium dioxyde bigira uruhare runini mukurema ibishishwa bya bombo kandi byiza kandi byiza bigaragara twese dukunda. Ubushobozi bwayo bwo kuzamura amabara, kunoza imiterere no gutanga ubuso burabagirana bituma biba ingirakamaro mubakora ibicuruzwa. Hamwe n’amabwiriza akomeye ashyirwaho kugirango umutekano wabo ubeho, abaguzi barashobora gukomeza kwishimira ibiryo bakunda bombo batewe na bombo batiriwe bahangayikishwa no gukoresha dioxyde de titanium yo mu rwego rwo hejuru.

Ingano imwe:
Dioxyde de titanium yibiribwa igaragara kubunini bwayo bumwe. Uyu mutungo ugira uruhare runini mukuzamura imikorere yawo nk'inyongeramusaruro. Ingano ihoraho itanga uburyo bwiza mugihe cyo kubyara, ikumira gukwirakwizwa cyangwa gukwirakwizwa kutaringaniye. Iyi miterere ituma ikwirakwizwa ryinyongeramusaruro, iteza imbere ibara nuburyo buhoraho mubicuruzwa byinshi byibiribwa.
Gutatana neza:
Ikindi kintu cyingenzi kiranga ibiryo byo mu rwego rwa titanium dioxyde ni nziza cyane. Iyo wongeyeho ibiryo, ikwirakwira byoroshye, ikwirakwira neza muruvange. Iyi mikorere ituma habaho gukwirakwiza inyongeramusaruro, bikavamo amabara ahoraho no kongera umutekano wibicuruzwa byanyuma. Gukwirakwiza gukwirakwiza ibiryo byo mu rwego rwa titanium dioxyde ituma bihuza neza kandi bikongerera imbaraga ibicuruzwa bitandukanye byibiribwa.
Imiterere ya pigment:
Dioxyde de titanium yo mu rwego rwo hejuru ikoreshwa cyane nka pigment kubera imikorere yayo ishimishije. Ibara ryera ryera rituma ihitamo gukundwa cyane nka kondete, amata n'ibicuruzwa bitetse. Ikigeretse kuri ibyo, imiterere ya pigment itanga ubwiza buhebuje, bufite akamaro ko gukora ibiribwa bifite imbaraga kandi bigaragara neza. Dioxyde de titanium yo mu rwego rwo hejuru yongerera imbaraga ibiryo byibiribwa, ikabigira ikintu cyingirakamaro mwisi yo guteka.
