Ọdụdọ Titanium Ọkwa Nri: Njirimara, Ngwa na Nchekwa Nchekwa

Okwu mmalite:

Titanium dioxide (TiO2) bụ ịnweta sitere n'okike nke ejirila mee ihe dị ka pigmenti ọcha na ngwa ụlọ ọrụ dị iche iche maka ọmarịcha opacity na nchapụta ya. N'ime afọ ndị na-adịbeghị anya, titanium dioxide achọtawokwa ụzọ ya n'ime ụlọ ọrụ nri dị ka ihe mgbakwunye nri, nke a maara dị ka titanium dioxide nke ọkwa nri. N'edemede a, anyị ga-enyocha njirimara, ngwa, ihe nchekwa, na usoro nhazi nke titanium dioxide ọkwa nri.

Njirimara nke Titanium Dioxide Ọkwa nri:

titanium dioxide nke ọkwa nri na-ekerịta ọtụtụ ihe ya na ndị otu ụlọ ọrụ mmepụta ihe, mana yana nlebara anya akọwapụtara maka nchekwa nri. Ọ na-adịkarị n'ụdị ntụ ntụ dị mma, nke na-acha ọcha ma mara ya maka nhụsianya dị elu, nke na-enye ya ọmarịcha opacity na nchapụta. A na-ejikwa nlezianya na-achịkwa nha nke ihe oriri-ọkwa titanium dioxide iji hụ na mgbasa otu na obere mmetụta na udidi ma ọ bụ uto na ngwaahịa nri. Na mgbakwunye, titanium dioxide nke ọkwa nri na-edobekarị usoro nchacha siri ike iji wepụ adịghị ọcha na mmetọ, na-ahụ na ọ dabara maka ojiji na ngwa nri.

Ụzọ mmepụta:

Enwere ike imepụta titanium dioxide ọkwa nri site na iji ụzọ eke na nke sịntetik. A na-enweta titanium dioxide eke sitere na nkwụnye ego ịnweta, dị ka rutile na ilmenite, site na usoro dị ka mmịpụta na ịdị ọcha. N'aka nke ọzọ, a na-emepụta titanium dioxide sịntetik site na usoro kemịkalụ, na-agụnye mmeghachi omume nke tetrachloride titanium na oxygen ma ọ bụ sọlfọ dioxide na oke okpomọkụ. N'agbanyeghị usoro mmepụta ihe, usoro njikwa mma dị mkpa iji hụ na titanium dioxide ọkwa nri na-ezute oke ịdị ọcha na ụkpụrụ nchekwa.

Ngwa na ụlọ ọrụ nri:

titanium dioxide ọkwa nri na-arụ ọrụ bụ isi dị ka ihe na-acha ọcha na opacifier n'ọtụtụ ngwaahịa nri. A na-ejikarị ya eme ihe na confectionery, mmiri ara ehi, ngwaahịa esiri esi, na ụdị nri ndị ọzọ iji mee ka mma anya na ọdịdị nke ihe oriri dị. Dịka ọmụmaatụ, a na-agbakwunye titanium dioxide na mkpuchi swiiti iji nweta agba mara mma yana ngwaahịa mmiri ara ehi dị ka yogọt na ice cream iji meziwanye opacity na ude ha. N'ime ngwaahịa ndị e ghere eghe, titanium dioxide na-enyere aka ịmepụta ọdịdị na-egbuke egbuke na nke otu n'ime ngwaahịa dị ka ntu oyi na ngwakọta achicha.

Ọkwa usoro na ntụle nchekwa:

Nchekwa nke titanium dioxide ọkwa nri bụ isiokwu nke arụmụka na-aga n'ihu na nyocha usoro iwu. Ndị na-ahụ maka nchịkwa gburugburu ụwa, gụnyere nri na ọgwụ ọjọọ (FDA) na United States na European Safety Safety Authority (EFSA) na Europe, enyochala nchekwa nke titanium dioxide dị ka ihe mgbakwunye nri. Ọ bụ ezie na a na-amatakarị titanium dioxide dị ka nchekwa (GRAS) mgbe ejiri ya n'ime oke a kapịrị ọnụ, ewelitela nchegbu banyere ihe egwu ahụike nwere ike jikọta na oriri ya, ọkachasị n'ụdị nanoparticle.

Mmetụta ahụike enwere ike:

Nnyocha e mere egosiwo na ndị nanoparticles titanium dioxide, nke dị ntakịrị karịa 100 nanometer n'ịdị elu, nwere ike ịbanye n'ime ihe mgbochi ndụ na ịkwakọba n'ime anụ ahụ, na-ewelite nchegbu banyere nchekwa ha. Nnyocha ụmụ anụmanụ egosiwo na nnukwu dose nke titanium dioxide nanoparticles nwere ike ịkpata mmetụta ọjọọ na imeju, akụrụ, na akụkụ ahụ ndị ọzọ. Ọzọkwa, e nwere ihe àmà na-egosi na titanium dioxide nanoparticles nwere ike ịkpata nrụgide oxidative na mbufụt na sel, nwere ike inye aka na mmepe nke ọrịa na-adịghị ala ala.

Atụmatụ Mbelata na Nhọrọ:

Iji lebara nchegbu banyere nchekwa nke titanium dioxide ọkwa nri, a na-eme mbọ iji mepụta ihe ndị ọzọ na-acha ọcha na ihe mkpuchi nke nwere ike nweta mmetụta yiri nke ahụ na-enweghị ihe ize ndụ ahụike. Ụfọdụ ndị na-emepụta ihe na-enyocha ihe ndị ọzọ sitere n'okike, dị ka calcium carbonate na osikapa starch, dị ka ndị na-anọchi anya titanium dioxide na ụfọdụ ngwa nri. Na mgbakwunye, ọganihu na teknụzụ nanotechnology na injinịa urughuru nwere ike inye ohere iji belata ihe egwu metụtara nanoparticles titanium dioxide site na imepụta urughuru mma yana mgbanwe elu.

Mmata ndị ahịa na ntinye aha:

Ịkpọ aha n'ụzọ doro anya na agụmakwụkwọ ndị ahịa dị mkpa maka ịgwa ndị na-azụ ahịa ihe gbasara ọnụnọ nke ihe mgbakwunye nri dị ka titanium dioxide na ngwaahịa nri. Ịkpọ aha doro anya na nke ziri ezi nwere ike inyere ndị na-azụ ahịa aka ịme nhọrọ mara mma ma zere ngwaahịa nwere mgbakwunye nke ha nwere ike inwe mmetụta ma ọ bụ nchegbu.

Echiche Ọdịnihu na ntụzịaka nyocha:

Ọdịnihu nke titanium dioxide ọkwa nri dabere na mbọ nyocha na-aga n'ihu iji ghọta profaịlụ nchekwa ya nke ọma yana mmetụta ahụike nwere ike. Ọganihu na-aga n'ihu na nanotoxicology, nyocha mkpughe, na nleba anya ihe ize ndụ ga-adị oke mkpa maka ịme mkpebi nhazi yana hụ na ojiji titanium dioxide dị mma na ngwa nri. Na mgbakwunye, nyocha n'ime ihe ndị ọzọ na-eme ka ịcha ọcha na opacifiers nwere nkwa maka ilebara nchegbu ndị ahịa anya na ịkwọ ụgbọala ọhụrụ na ụlọ ọrụ nri.

Mmechi:

Nri titanium dioxide na-arụ ọrụ dị mkpa na ụlọ ọrụ nri dị ka onye na-acha ọcha na opacifier, na-eme ka mmasị na-ahụ anya na ọdịdị dị iche iche nke ngwaahịa nri.
