I-Titanium Dioxide

I-Titanium dioxide (TiO2) yi-pigment emhlophe esetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa.Nantsi isishwankathelo se-titanium dioxide, iipropathi zayo, kunye nokusetyenziswa kwayo okwahlukeneyo:

1. Ukubunjwa kwemichiza: I-Titanium dioxide yioksidi yendalo ye-titanium eyenzeka ngokwendalo kunye nefomula yeekhemikhali i-TiO2.Ikho kwiifom ezininzi zekristali, kunye ne-rutile kunye ne-anatase zezona ziqhelekileyo.I-Rutile TiO2 yaziwa ngokuba yi-index ephezulu ye-refractive kunye ne-opacity, ngelixa i-anatase TiO2 ibonisa umsebenzi ophezulu we-photocatalytic.
2. Ibala Elimhlophe: Enye yezona zinto zisetyenziswa kakhulu ititanium dioxide kufana nebala elimhlophe kwipeyinti, kwizinto zokwaleka, iiplastiki nephepha.Inika ukukhanya, ukungafihli, kunye nobumhlophe kwezi zixhobo, izenza zibe nomtsalane ngokubonakalayo kwaye ziphucule ukugquma kwazo kunye namandla okufihla.I-Titanium dioxide ikhethwa ngaphezu kwezinye ii-pigments ezimhlophe ngenxa yeempawu zayo ezibalaseleyo zokusasaza ukukhanya kunye nokuxhathisa ukuguquka kombala.
3. I-UV Absorber kunye ne-Sunscreen: I-Titanium dioxide isetyenziswa ngokubanzi njenge-Absorbent ye-UV kwi-sunscreens kunye neemveliso zokuthambisa.Isebenza njenge-sunscreen ebonakalayo ngokubonakalisa kunye nokusasaza imitha ye-UV, ngaloo ndlela ikhusela ulusu kwimiphumo eyingozi efana nokutshiswa lilanga, ukuguga kwangaphambili, kunye nomhlaza wolusu.Amasuntswana e-nanoscale titanium dioxide ahlala esetyenziswa kwifom ye-sunscreen ukwenzela ukungafihli kunye nokhuseleko olubanzi lwe-UV.
4. I-Photocatalyst: Iintlobo ezithile ze-titanium dioxide, ngakumbi i-anatase TiO2, ibonisa umsebenzi we-photocatalytic xa ibonakaliswe kukukhanya kwe-ultraviolet.Lo mhlaba wenza ukuba i-titanium dioxide ikwazi ukwenza utshintsho kwiikhemikhali ezahlukeneyo, njengokubola kongcoliseko lwendalo kunye nokuvalwa komgangatho.Ifotocatalytic titanium dioxide isetyenziswa kwiingubo zokuzicoca, iinkqubo zokucoca umoya, kunye nezicelo zokucoca amanzi.
5. Ukongezwa kokutya: I-Titanium dioxide ivunyiwe njengesongezo sokutya (E171) ngamaqumrhu alawulayo afana ne-FDA kunye ne-European Food Safety Authority (EFSA).Isetyenziswa ngokuqhelekileyo kwiimveliso zokutya, ezifana ne-confectionery, iimpahla ezibhakiweyo, kunye neemveliso zobisi, njenge-agent emhlophe kunye ne-opacifier.I-Titanium dioxide inceda ekuphuculeni inkangeleko kunye nokwakheka kwezinto zokutya, izenza zibe nomtsalane ngakumbi kubathengi.
6. INkxaso yeCatalyst: I-Titanium dioxide isebenza njengenkxaso ye-catalyst kwiinkqubo ezahlukeneyo zeekhemikhali, kubandakanywa ne-heterogeneous catalysis kunye nokulungiswa kwendalo.Inika indawo ephezulu kunye nenkxaso ezinzileyo yeendawo ezisebenzayo, iququzelela ukusabela okusebenzayo kweekhemikhali kunye nokuthotywa kongcoliseko.Ii-catalysts ezixhaswa yi-Titanium dioxide zisetyenziswa kwizicelo ezifana nokucocwa kombhobho wemoto, ukuveliswa kwe-hydrogen, kunye nokucocwa kwamanzi amdaka.
7. I-Electroceramics: I-Titanium dioxide isetyenziselwa ukuveliswa kwezinto ze-electroceramic, ezifana ne-capacitors, i-varistors, kunye ne-sensor, ngenxa yeempawu zayo ze-dielectric kunye ne-semiconductor.Isebenza njengento ephezulu-k ye-dielectric kwi-capacitors, eyenza ukugcinwa kwamandla ombane, kunye ne-gas-sensitive material kwi-sensors zokubona iigesi kunye ne-volatile organic compounds.

Isishwankathelo, i-titanium dioxide yimpahla eguquguqukayo enoluhlu olubanzi lwezicelo, kubandakanywa njenge-pigment emhlophe, i-Absorbent ye-UV, i-photocatalyst, i-additive yokutya, inkxaso ye-catalyst, kunye ne-electroceramic component.Ukudityaniswa kwayo okukhethekileyo kweepropathi kuyenza ibaluleke kakhulu kumashishini afana neepeyinti kunye neengubo, izinto zokuthambisa, ukulungiswa kokusingqongileyo, ukutya, i-elektroniki kunye nokhathalelo lwempilo.
