Yintoni iTitanium Dioxide yeBanga leZithambiso?
I-Titanium dioxide (TiO₂) sisihluzo se-UV seminerali esingabonakaliyo kunye nombala omhlophe osetyenziswa kakhulu kwizithambiso, kwi-sunscreens, kwiiyeza, ekutyeni, nakwiingubo. Kwikhemistri yelanga, i-TiO₂ isebenza njengesihluzo se-UV esibonakalayo (seminerali) - siyasasaza, sibonakalise, kwaye sifunxa imitha ye-UV endaweni yokuyifunxa kwaye siyikhuphe kwakhona njengezihluzo ze-UV zendalo (ii-sunscreens zekhemikhali). I-TiO₂ ye-cosmetic-grade ifumaneka kwiindidi ezimbini eziphambili zobukhulu be-particle: i-non-nano (i-pigment grade, >100 nm) ebonelela nge-opacity ephezulu kunye nobumhlophe kunye nokukhuselwa kwe-UV, kunye ne-nano/microfine grade (ubukhulu be-particle obuphambili buhlala buyi-10–50 nm), ebonelela ngokhuseleko lwe-UV ngesiphumo esinciphileyo sokuba mhlophe, esibalulekileyo kwi-sunscreen formulations ezinombala kwaye ezinobuhlobo nolusu.
Ukwenziwa kwe-Sunscreen kunye ne-Cosmetic
I-Microfine TiO₂ kwii-sunscreens ibonelela ngokhuseleko lwe-UV olubanzi kwi-UVB (290–320 nm) kunye ne-UVA II (320–340 nm). Ugutyungelwe yi-UVA I (340–400 nm) aluphelelanga kangako kune-avobenzone okanye i-zinc oxide, ngoko ke idla ngokudityaniswa nezihluzi ze-zinc oxide okanye ze-organic UVA ukuze kukhuselwe ngokupheleleyo i-UVA I kwiimveliso ze-SPF ephezulu. Amanqanaba e-TiO₂ agqunywe ngumphezulu (i-hydrophilic coatings kwiinkqubo ezisasazeka ngamanzi, i-hydrophobic coatings ze-anhydrous kunye ne-oyile formulations) zibonelelwa kwiinkqubo ezithile zokwenziwa. Kwizinto zokuthambisa ezinemibala (iziseko, iipowders ezicinezelweyo, ii-BB creams), i-TiO₂ ye-pigment-grade ibonelela ngombala omhlophe, ukungabonakali, kunye nogutyungelwe.
Izicelo zeMizi-mveliso
Kwiipeyinti kunye neengubo, iTiO₂ yeyona pigment imhlophe iphambili kwihlabathi liphela, inika amandla okufihla, ukukhanya, kunye nozinzo lwe-UV. Kwiiplastiki, ephepheni, nakwii-inki inika ukukhanya kunye nobumhlophe. ITiO₂ (E171) yodidi lokutya iphantsi kophononongo lwemithetho kwi-EU (okwangoku imisiwe ukusetyenziswa kokutya) kodwa isaqhubeka nokuba ngumbala kwiivenkile zeelekese kwiimarike ezininzi. I-Terracore Chemicals inikezela ngeTiO₂ kudidi lwezithambiso, amayeza, kunye nemizi-mveliso kulo lonke elaseMzantsi Afrika.
izicelo
