Uhlobo lwe-Rutile

Incazelo emfushane:

I-Titanium dioxide iwuketshezi lwamakhemikhali angaphili, olusetshenziswa kakhulu ekukhiqizeni izimboni ezifana nezingubo, amapulasitiki, irabha, ukwenza iphepha, oyinki bokuphrinta, imicu yamakhemikhali, nezimonyo. I-Titanium dioxide inezinhlobo ezimbili zekristalu: i-rutile ne-anatase. Rutile titanium dioxide, okungukuthi, R-uhlobo titanium dioxide; i-anatase titanium dioxide, okungukuthi, uhlobo lwe-A-titanium dioxide.
I-Rutile titanium dioxide inezinto ezinhle kakhulu ezifana nokumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi, ukumelana nokugqwala, amandla aphezulu, namandla adonsela phansi amancane. Uma iqhathaniswa ne-anatase titanium dioxide, inokumelana nesimo sezulu esiphezulu nomsebenzi ongcono we-photooxidative. Uhlobo lwe-Rutile (uhlobo R) lunokuminyana okungu-4.26g/cm3 kanye nenkomba ye-refractive engu-2.72. I-titanium dioxide yohlobo lwe-R inezici zokumelana nesimo sezulu esihle, ukumelana namanzi futhi akulula ukuphenduka ibe phuzi. I-Rutile titanium dioxide inezinzuzo eziningi ezinhlelweni ezihlukahlukene. Ngokwesibonelo, ngenxa yendlela eyakhiwe ngayo, i-pigment eyikhiqizayo ishintshashintsha ngombala futhi kulula ukuyibala. Inamandla ombala oqinile futhi ayilimazi indawo engaphezulu. Umbala omaphakathi, nombala ugqamile, akulula ukufiphala.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Inkambu yohlelo lokusebenza

I-Titanium dioxide ayisetshenziswa nje kuphela njengombala embonini yenjoloba, kodwa futhi inemisebenzi yokuqinisa, ukulwa nokuguga nokugcwalisa. Ukwengeza i-titanium dioxide emikhiqizweni yenjoloba neyepulasitiki, ngaphansi kokukhanya kwelanga, imelana nokukhanya kwelanga, ayiqhekeki, ayishintshi umbala, inobude obuphakeme kanye nokumelana ne-asidi ne-alkali. I-Titanium dioxide yenjoloba isetshenziswa kakhulu kumathayi ezimoto, ezicathulweni zenjoloba, phansi kwerabha, amagilavu, izinto zezemidlalo, njll., futhi ngokuvamile i-anatase iwuhlobo oluyinhloko. Kodwa-ke, ukuze kukhiqizwe amathayi ezimoto, inani elithile lemikhiqizo ye-rutile livame ukungezwa ukuze kuthuthukiswe amandla e-anti-ozone kanye ne-anti-ultraviolet.

I-Titanium dioxide nayo isetshenziswa kakhulu ezimonyoni. Ngenxa yokuthi i-titanium dioxide ayinabo ubuthi futhi iphakeme kakhulu kunomhlophe oholayo, cishe zonke izinhlobo zempuphu yephunga zisebenzisa i-titanium dioxide esikhundleni somhlophe womthofu kanye ne-zinc emhlophe. Kuphela u-5% -8% we-titanium dioxide wengezwa kumpushana ukuze uthole umbala omhlophe ongapheli, okwenza iphunga libe nokhilimu, ngokunamathela, ukumuncwa namandla okuvala. I-Titanium dioxide inganciphisa umuzwa wokunamafutha futhi osobala ku-gouache nokhilimu obandayo. I-Titanium dioxide iphinde isetshenziswe kwezinye iphunga elimnandi, izinto zokuvikela ilanga, ama-soap flakes, insipho emhlophe kanye nomuthi wokuxubha.

Imboni yokumboza: Izingubo zokugqoka zihlukaniswe zibe izimbotshana zezimboni kanye nezingubo zezakhiwo. Ngokuthuthuka kwemboni yezokwakha kanye nemboni yezimoto, isidingo se-titanium dioxide sikhula usuku nosuku, ikakhulukazi uhlobo lwe-rutile.

I-koqweqwe lwawo olwenziwe nge-titanium dioxide lunokucaca okuqinile, isisindo esincane, ukumelana nomthelela onamandla, izakhiwo ezinhle zemishini, imibala ekhanyayo, futhi akulula ukungcolisa. I-Titanium dioxide yokudla nemithi i-titanium dioxide enokuhlanzeka okuphezulu, okuqukethwe kwensimbi esindayo ephansi namandla okucasha aqinile.
