Ukuqonda Umahluko phakathi kweTiO2 Rutile kunye neAnatase

 I-Titanium dioxide(TiO2) i-pigment eguquguqukayo esetyenziswa kumashishini ahlukeneyo, kuquka iipeyinti, iingubo, iiplastiki kunye nezithambiso. Ikho kwiifom ezimbini eziphambili zekristale: i-rutile kunye ne-anatase. Ukuqonda umahluko phakathi kwezi fom zimbini kubalulekile ekukhetheni uhlobo oluchanekileyo lwe-TiO2 lwesicelo esithile.

I-Rutile kunye ne-anatase zombini iintlobo ze-titanium dioxide, kodwa zineempawu ezahlukeneyo ezenza ukuba zilungele ukusetyenziswa okwahlukeneyo. I-Rutile yaziwa ngokugqwesa kwayo kwi-UV kunye nokumelana nemozulu, iyenza ibe lukhetho oludumileyo kwizicelo zangaphandle ezinje ngeepeyinti zangaphandle kunye neengubo. I-Anatase, ngakolunye uhlangothi, ixabiswa ngomsebenzi wayo ophezulu we-photocatalytic, okwenza kube yinto efanelekileyo kwizicelo ezifana neengubo zokuzicoca kunye neenkqubo zokucoca umoya.

Enye yeeyantlukwano eziphambili phakathi kwe-rutile kunye ne-anatase yi-crystal structure yabo. I-Rutile ine-tetragonal crystal structure, ngelixa i-anatase ine-orthorhombic crystal structure eyinkimbinkimbi. Lo mahluko wesakhiwo ukhokelela ekutshintsheni kwiimpawu zabo zomzimba kunye neekhemikhali, ekugqibeleni zichaphazela ukusebenza kwazo kwizicelo ezahlukeneyo.

Ngokubhekiselele kwiipropati ze-optical,rutile TiO2inesalathisi esiphezulu se-refractive kunye ne-opacity kune-anatase. Oku kwenza i-rutile ibe yinto yokuqala yokukhetha kwizicelo apho ukukhanya kunye nokukhanya kubaluleke kakhulu, njengepeyinti ezimhlophe kunye neengubo. I-Anatase, ngakolunye uhlangothi, ine-index ye-refractive ephantsi kwaye isoloko isetyenziswa kwizicelo apho kufuneka ukukhanya kunye nokucaca, ezifana neengubo ezicacileyo kunye ne-sunscreens.

Enye into ebalulekileyo ekufuneka uyiqwalasele xa ukhetha phakathi kwe-rutile kunye ne-anatase TiO2 ngumsebenzi wabo we-photocatalytic. I-Anatase inokusebenza okuphezulu kwe-photocatalytic kune-rutile, iyenza ifaneleke kwizicelo ezifuna iipropati zokuzicoca kunye nokunciphisa ungcoliseko. Le propati ibangele ukusetyenziswa kwe-anatase titanium dioxide kwiimveliso ezifana neglasi yokucoca, iinkqubo zokucoca umoya kunye neengubo zokulwa ne-antimicrobial.

Kwakhona kuyafaneleka ukuba uqaphele ukuba iinkqubo zokuvelisa i-rutile TiO2 kunyeanatase iTiO2zinokwahluka, kubangele iyantlukwano kubungakanani bamasuntswana, indawo yomphezulu, kunye neempawu zeagglomeration. Ezi zinto zinokuchaphazela ukusasazeka, ukuzinza kunye nokusebenza kwe-TiO2 kwiifom ezahlukeneyo, ngakumbi ukugxininisa ukubaluleka kokukhetha uhlobo olufanelekileyo lwesicelo esithile.

Isishwankathelo, umahluko phakathi kwe-rutile TiO2 kunye ne-anatase TiO2 yandisa ngaphaya kwezakhiwo zabo zekristale ukuya kwiipropathi zabo ze-optical, photocatalytic, kunye nokucubungula. Ukuqonda lo mahluko kubalulekile ekwenzeni izigqibo ezizizo xa ukhetha i-TiO2 kwiintlobo ngeentlobo zezicelo. Ngokukhetha uhlobo olufanelekileyo lwe-titanium dioxide, abavelisi banokwandisa ukusebenza kunye nokusebenza kweemveliso zabo, ekugqibeleni bahlangabezane neemfuno ezithile zabasebenzisi bokugqibela.
