Chii chinoshandiswa neTitanium Dioxide?
Nzvimbo dzekushandisa dzechinyakare
1. Pigments uye zvinhu zvinovanza
Indasitiri yekupenda: Seruvara ruchena, rinopa kuchena kwakanyanya (L>98) uye simba rakasimba rekuviga (>95%) kukupenda uku richivandudza kusimba kwemamiriro ekunze (kupfuura bvunzo yeQUV-A 2000h).
Mapurasitiki nekugadzira mapepa: Zvinowedzera kupenya (>90%) uye hunhu hwepurasitiki hunodzivirira yero; zvinoshandiswa pakugadzirisa pamusoro pepepa remhando yepamusoro kuti riwedzere kupenya uye kudhindwa.
2. Zviumbwa zvesimbi uye enamel
Kugadziriswa kweGlaze: Sechinhu chinodzivirira chiedza uye chinochenesa, chinogona kuvandudza kuomarara (kuomarara kweMohs ≥ 6), kupenya (kupenya kwechiedza > 85%) uye kuramba acid (kuramba kwe10% HCl solution > 24h) kwegirazi.
3. Makemikoro ezuva nezuva nechikafu
Zvigadzirwa zvekudzivirira zuva: Zvinodzivirira zuva nemwaranzi ye ultraviolet (UVA/UVB bands), uye nano-scale TiO₂ (saizi yezvikamu ≤100nm) zvinogona kudzivirira kunzwa kweganda rinonamira.
Chinowedzera chikafu: Sepigment chena isina chepfu (inoenderana neFDA 21CFR73.575), inoshandiswa pakuchenesa masiwiti, zvigadzirwa zvemukaka, nezvimwewo.

Nzvimbo dziri kutsva dzekushandisa
1. Kutungamirirwa kwezvakatipoteredza
Kuora kwepurasitiki: Zvinhu zvinoyangarara zve titanium dioxide zvinogona kuora kana zvisina kusimba kuburikidza nepamusoro pe hydrophobic layer pasina chikonzero chekugadzirisa acid/alkali yakasimba, zvichiwedzera kushanda zvakanaka kwemapurasitiki e polyethylene kakawanda, ethanol ichiita 40% yechigadzirwa.
Kucheneswa kwemhepo: 5nm inoshanda nano-TiO₂ photocatalyst inogona kuora tsvina yakaita se formaldehyde ne benzene (chiyero chekuora kwemhepo > 98%), uye simba rayo rekushanda rinosvika kubhendi rechiedza rinoonekwa (rinopfuura 400nm).
2. Tekinoroji yeSimba
Kupatsanurwa kwemvura inokamura kuti ibudise hydrogen: Rutile TiO₂ inosanganiswa neScandium inowedzera kushanda kwe photogenerated charge separation ne200, uye mwero wekugadzirwa kwehydrogen wakapetwa ka15 pane wezvinhu zvechinyakare (pasi pezuva rakaedzwa).
Zvinhu zvitsva zvesimba: zvinoshandiswa pakugadzira lithium battery positive electrode coating kudzivirira electrode side reactions uye kuvandudza kugadzikana kwe cycle (>4000 times @80% SOH).
3. Kugadziriswa kwezvinhu zvinoshanda
Kuputira mabhakitiriya: Nano-titanium sol inopinda mu substrate kuti igadzire ganda rakakora, ine mwero wekuuraya we >98% pakurwisa E. coli nemamwe mabhakitiriya, uye kushanda kwayo kunoderera ne <5% mushure mekukwegura kwemakore mashanu.
Zvivako zvinodzivirira mamiriro ekunze zvakanyanya: TiO₂ ine cerium yakawanda inowedzera kusimba kweUV pamadziro ekunze (UVA shielding rate > 99%) uye inowedzera kusimba kwechando ne50%.
Kuvhara kwemaziso: Hunhu hwepamusoro hwe refractive index (nd=1.75-2.20) hunoshandiswa pakuvhara kwe anti-reflection kuderedza kurasikirwa kwemaziso mumidziyo ye laser (<0.1dB/km).
4.Kubatsira Kwakakosha Muindasitiri
Kugadzirwa kwemakemikari: Sechinhu chinobatsira kuburitsa olefin epoxidation, chiyero chekushandura chiri >95%; mu photocatalytic water splitting hydrogen production system, inosanganiswa neCdS kuti ivandudze kushanda zvakanaka kwekugadzira hydrogen.

Kuchengetedzeka uye Kutevedzera Mutemo
Kurongwa kwezvekufambisa: Zvinhu Zvisiri Ngozi (ZVISINA NGOZI)
Chitupa chezvakatipoteredza:
- RoHS 3.0 (2015/863/EU) Simbi dzinorema hadzina kuonekwa
- Zvinhu zvisina kunyorwa pasi peREACH SVHC
- Kutevedzera Mutemo weConflict Minerals (CMRT 6.0)
Kuchengetedzeka pabasa: Muganho weOSHA TWA 5mg/m³ (guruva)
Zvekungwaririra
Kuvhiyiwa kweNanopowder kunoda dziviriro yekufema yeN95 (inoenderana neISO 13137)
Pakushandisa tembiricha yepamusoro, zvinokurudzirwa kushandisa ma "corundum crucibles"
Zvigadzirwa zvemhando yepamusoro yechikafu/mishonga zvinofanirwa kupa magwaro ekutevedzera mitemo yeCOA neFDA
