I-Titanium Dioxide isetshenziselwa ini?
Izindawo zokusetshenziswa zendabuko
1. Ama-pigment kanye nezinto zokufihla
Imboni yezingubo zokumboza: Njenge-pigment emhlophe, inikeza ubumhlophe obuphezulu (L>98) kanye namandla okufihla aqinile (>95%) endwangu ngenkathi ithuthukisa ukumelana nesimo sezulu (idlula ukuhlolwa kwe-QUV-A 2000h).
Amapulasitiki kanye nokwenza amaphepha: Kwandisa ukungabonakali (>90%) kanye nezakhiwo zokulwa nokuphuzi kwemikhiqizo yepulasitiki; kusetshenziselwa ukwelashwa kobuso bephepha eliphezulu ukuze kuthuthukiswe ukucwebezela nokunyatheliswa.
2. Izinto zobumba kanye ne-enamel
Ukuguqulwa kwe-glaze: Njenge-ejenti yokuvikela ukukhanya kanye ne-ejenti yokwenza mhlophe, ingathuthukisa ubulukhuni (ubulukhuni be-Mohs ≥ 6), ukukhanya (ukukhanya > 85%) kanye nokumelana ne-asidi (ukumelana nesisombululo se-HCl esingu-10% > amahora angu-24) sobuso be-glaze.
3. Amakhemikhali nokudla kwansuku zonke
Imikhiqizo ye-Sunscreen: Ihlinzeka ngokuvikelwa kwelanga ngokomzimba ngokusabalalisa imisebe ye-ultraviolet (ama-UVA/UVB bands), kanye ne-nano-scale TiO₂ (usayizi wezinhlayiya ≤100nm) ingagwema umuzwa wesikhumba onamathelayo.
Isithasiselo sokudla: Njenge-pigment emhlophe engenabo ubuthi (ehambisana ne-FDA 21CFR73.575), isetshenziselwa ukwenza amaswidi abe mhlophe, imikhiqizo yobisi, njll.

Izindawo zokufaka izicelo ezisafufusa
1. Ukuphathwa kwemvelo
Ukuwohloka kwepulasitiki: Izinto ze-titanium dioxide ezintantayo zingawohloka ngaphansi kwezimo ezingathathi hlangothi ngokusebenzisa ungqimba olungaphandle olungenamanzi ngaphandle kwesidingo sokwelashwa kwangaphambili kwe-asidi/alkali enamandla, okwandisa ukusebenza kahle kokubola kwepulasitiki ye-polyethylene izikhathi eziningi, kanti i-ethanol ibalwa ku-40% womkhiqizo.
Ukuhlanzwa komoya: I-photocatalyst esebenzayo engu-5nm nano-TiO₂ ingabola ukungcola okufana ne-formaldehyde ne-benzene (izinga lokubola > 98%), futhi ububanzi bayo besenzo bufinyelela ebhendini yokukhanya ebonakalayo (ngaphezu kuka-400nm).
2. Ubuchwepheshe Bamandla
Ukuhlukana kwamanzi nge-photocatalytic ukukhiqiza i-hydrogen: I-rutile TiO₂ efakwe i-Scandium ikhulisa ukusebenza kahle kokuhlukaniswa kweshaja ekhiqizwa nge-photo ngokuphindwe ka-200, kanti izinga lokukhiqizwa kwe-hydrogen liphindwe ka-15 kunelezinto zendabuko (ngaphansi kwelanga elilingisiwe).
Izinto ezintsha zamandla: ezisetshenziselwa ukumbozwa kwe-electrode enebhethri le-lithium ukuvimbela ukusabela okuseceleni kwe-electrode nokuthuthukisa ukuzinza komjikelezo (>izikhathi ezingu-4000 @80% SOH).
3. Ukuguqulwa kwezinto ezisebenzayo
Ukugqoka okulwa namagciwane: I-Nano-titanium sol ingena ngaphansi komhlabathi ukuze yakhe ungqimba oluqinile, ngesilinganiso sokubulala esingu->98% ngokumelene ne-E. coli namanye amagciwane, kanye nokwehla kokusebenza okungu-<5% ngemva kokuguga iminyaka emi-5.
Izinto zokwakha ezimelana kakhulu nesimo sezulu: I-TiO₂ enomhlaba ongavamile we-cerium ithuthukisa ukumelana kwe-UV kwezingubo zangaphandle zodonga (izinga lokuvikela i-UVA > 99%) futhi ithuthukisa ukumelana nokuqandisa ngo-50%.
Ukugqoka okubonakalayo: Izakhiwo zenkomba ephezulu yokugqama (nd=1.75-2.20) zisetshenziselwa ukugqoka okulwa nokukhanya ukuze kuncishiswe ukulahlekelwa ukukhanya kumadivayisi e-laser (<0.1dB/km).
4. I-Specialty Industrial Catalysis
Ukwenziwa kwamakhemikhali: Njenge-catalyst ye-olefin epoxidation, izinga lokuguqulwa lingu->95%; ohlelweni lokukhiqiza i-hydrogen oluhlukanisa amanzi nge-photocatalytic, luhlanganiswa ne-CdS ukuthuthukisa ukusebenza kahle kokukhiqiza i-hydrogen.

Izinyathelo zokuzivikela
Ukusebenza kwe-nanopowder kudinga ukuvikelwa kokuphefumula kwe-N95 (kuhambisana ne-ISO 13137)
Uma kusetshenziswa amazinga okushisa aphezulu, kunconywa ukusebenzisa izitsha zokubhaka ze-corundum
Imikhiqizo yokudla/yemithi kumele ihlinzeke ngemibhalo yokuthobela imithetho ye-COA kanye ne-FDA
---
Incazelo engenhla isekelwe ezicini ezijwayelekile ze-titanium dioxide. Ukuze uthole izixazululo ezithile zokusetshenziswa kanye namapharamitha, sicela ubheke i-COA yomkhiqizo (umbiko wokuhlolwa kwekhwalithi) kanye nefayela le-MSDS.
