I-Titanium dioxide (I-TiO2) sisibala esimhlophe esisebenza ngeendlela ezininzi esisetyenziswa kumashishini ahlukeneyo, kuquka neshishini lephepha. Kwiminyaka yakutshanje, imfuno ephezulu ye-titanium dioxide, ngakumbi i-anatase titanium dioxide, iye yanyuka. I-China iye yaba ngumvelisi ohamba phambili we-anatase titanium dioxide, ebonelela ngezicelo ezintsha kwishishini lephepha.
I-Anatase titanium dioxide evela e-China ifumene ingqwalasela ebanzi ngenxa yokusebenza kwayo kakuhle kunye nokusetyenziswa okutsha kwishishini lephepha. I-Anatase ifom ye-crystalline ye-TiO2 enesalathisi esiphezulu se-refractive, iimpawu ezibalaseleyo zokusabalalisa ukukhanya kunye nomsebenzi ophuculweyo we-photocatalytic. Ezi zakhiwo ezizodwa zenza ukuba zilungele ukuphucula umgangatho kunye nokusebenza kweemveliso zephepha.
Enye yezicelo ezintsha ze-anatase yaseTshayinatitanium dioxidekwishishini lephepha lifana nepigment ephezulu yokusebenza. Xa idityaniswe kwiingubo zephepha, i-anatase titanium dioxide iphucula ukukhanya, ukuqaqamba kunye nobumhlophe bephepha. Oku kuphucula ukuchasana koshicilelo kunye nokuveliswa kombala, oko kuyenza ilungele ukuprintwa nokupakisha izicelo ezikumgangatho ophezulu.
Ukongezelela, i-anatase titanium dioxide evela eChina ineempawu ezintle zokusabalalisa ukukhanya, ezinceda ukuphucula iimpawu ze-optical zephepha. Ngokusasaza ii-pigments ngokulinganayo kulo lonke i-coating yephepha, inceda ukufikelela kwindawo egudileyo, ekhazimlayo eyandisa inkangeleko yephepha ngokubanzi kunye nokuprintwa.
Ukongeza kwiinzuzo zayo zokubona, i-anatase titanium dioxide evela e-China iphinda isebenze njenge-blocker ye-UV esebenzayo xa isetyenziswe kwiingubo zephepha. Olu phawu lubaluleke kakhulu kwiinkqubo apho imitha ye-UV kufuneka ikhuselwe, njengempahla yokupakisha kunye nemiqondiso yangaphandle. Ngokufaka i-anatase titanium dioxide, iimveliso zephepha zinokuphucula ukuqina kunye nokuxhathisa ukutyheli okubangelwa yi-UV.
Ngaphaya koko, umsebenzi we-photocatalytic we-anatase titanium dioxide uvula amathuba amatsha okuzicoca kunye neemveliso zephepha zokucoca umoya. Xa ibonakaliswe ekukhanyeni, i-titanium dioxide anatase inokubangela i-photocatalytic reaction eqhekeza i-organic compounds kunye nokungcola, inceda ukudala indawo ecocekileyo, enempilo. Esi sicelo sivelisa amandla amakhulu kumaphepha akhethekileyo asetyenziswa kucoceko, ukhathalelo lwempilo kunye nokuzinza kokusingqongileyo.
Ukuveliswa kwe-anatase titanium dioxide e-China kukwahambelana nogxininiso olwandayo lweshishini lephepha kwizinto ezizinzileyo kunye nezenzo ezihambelana nokusingqongileyo. Ngenkqubela phambili kwiinkqubo zokuvelisa kunye nokulawulwa komgangatho, ababoneleli baseTshayina bayakwazi ukubonelela ngokucoceka okuphezului-anatase titanium dioxideehlangabezana nemigangatho engqongqo yokusingqongileyo. Oku kwenza ukuba abavelisi bamaphepha bafake i-pigments ehambelana nokusingqongileyo kwiimveliso zabo, ukuhlangabezana neemfuno zabathengi kunye namashishini anomdla wokusingqongileyo.
Isishwankathelo, ukusetyenziswa okutsha kwe-anatase titanium dioxide yaseTshayina kuzise inkqubela phambili ebalulekileyo kushishino lokwenza iphepha. Iimpawu zayo eziyingqayizivele, ezibandakanya isalathisi esiphezulu se-refractive, amandla okusabalalisa ukukhanya, i-UV yokuthintela umphumo kunye nomsebenzi we-photocatalytic, yenza ukuba ibe yinto exabisekileyo yokongeza ukuphucula ukusebenza kunye nokuzinza kweemveliso zephepha. Njengoko imfuno yomgangatho ophezulu we-titanium dioxide iqhubeka nokukhula, ukusetyenziswa kwe-anatase yaseChina ngokuqinisekileyo kuya kukhuthaza inkqubela phambili kwishishini lokwenza iphepha kunye nokubonelela ngamathuba amatsha okuphucula umgangatho wemveliso kunye noxanduva lokusingqongileyo.
