Isticmaalka Titanium Dioxide ee Dahaadhka

Titanium dioxide, oo sidoo kale loo yaqaan titanium dioxide ama TiO ₂, wuxuu door muhiim ah ka ciyaaraa dahaarka, inta badan wuxuu ka muuqdaa hagaajinta daboolida, hagaajinta iska caabbinta cimilada, iyo hagaajinta kala firdhinta. Adeegsigeedu wuxuu daboolaa dhismayaasha, baabuurta, warshadaha, qalabka guryaha, iwm., iyadoo leh astaamo gaar ah sida soo socota:
Awoodda Daboolida: Tusmada sare ee dhalaalaysa (2.7) ee titanium dioxide waxay ka dhigaysaa isha ugu muhiimsan ee daboolida awoodda dahaarka, si wax ku ool ah u qarinaysa midabada substrate-ka iyo cilladaha, iyo gaarista dabool isku mid ah xitaa dahaarka khafiifka ah. Cilmi-baaristu waxay muujisay in marka cabbirka walxaha titanium dioxide uu yahay 160-350 nanometer (qiyaastii 0.4-0.5 jeer mowjadda iftiinka la arki karo), awoodda kala firdhinta iftiinka ayaa ah tan ugu xooggan saameynta daboolistana waa tan ugu fiican. Haddii walxaha sameeya filimka ee dahaarka aysan ku filnayn, walxaha titanium dioxide waxay u nugul yihiin isku-ururinta, taasoo keenta koror ku yimaada cabbirka walxaha dhabta ah iyo hoos u dhaca waxqabadka daboolida.
Iska caabbinta cimilada iyo cimri dhererka: Xasiloonida kiimikada ee titanium dioxide waxay dahaarka u horseedaa iska caabbinta shucaaca ultraviolet, roobka aashitada, iyo isbeddellada heerkulka, taasoo si weyn u kordhinaysa cimriga filimka rinjiga. Rutile titanium dioxide waxaa si weyn loogu isticmaalaa xaaladaha bannaanka sida dahaarka derbiga dibadda iyo dahaarka sare ee baabuurta sababtoo ah iska caabbinta cimilada oo sareysa, halka anatase titanium dioxide si caadi ah loogu isticmaalo dahaarka gudaha. Titanium dioxide ee dibadda laga keeno ayaa si gaar ah ugu fiican dahaarka heerka sare ah, maadaama ay iska caabin karto nabaad-guurka deegaanka ee daran waxayna ilaalin kartaa midabka dahaarka deggan.
Baahida kala firdhinta: Titanium dioxide waa in si siman loogu kala firdhiyaa walxaha salka dahaarka si looga fogaado isku-ururinta taasoo keeni karta dhalaal aan sinnayn ama hoos u dhaca xoogga farsamada. Dahaarka biyaha ku salaysan wuxuu u baahan yahay kala firdhis sare, farsamooyinka daaweynta dusha sarena waxaa loo baahan yahay si loo wanaajiyo iswaafajinta u dhaxaysa titanium dioxide iyo nidaamyada biyaha ku salaysan.
Xaaladaha codsiga:
Dahaarka dhismaha: Titanium dioxide wuxuu bixiyaa iska caabbinta cimilada ee dahaarka derbiga dibadda, wuxuu xoojiyaa caddaanka iyo daboolida dahaarka derbiga gudaha, wuxuuna daboolaa baahida loo qabo adkeynta biyaha iyo sare ee isbeddellada ilaalinta deegaanka;
Dahaadhada Gawaarida: Kordhi dhalaalka iyo iska caabbinta UV ee dahaarka jirka, ka hortagga libdhashada, oo kordhi cimriga dusha sare ee rinjiga;
Dahaarka warshadaha: waxaa loo isticmaalaa dahaarka birta ee ka hortagga daxalka, wuxuu iska caabiyaa daxalka deegaannada adag sida kiimikada iyo badda, wuxuuna yareeyaa kharashyada dayactirka qalabka;
Qalabka guryaha iyo dahaarka alwaaxa: waxay hagaajiyaan waxqabadka ka hortagga wasakhda ee qalabka guryaha iyo waxqabadka ka hortagga gabowga ee alaabta alwaaxa, iyagoo tixgelinaya quruxda iyo cimri dhererka.
Isbeddelka ilaalinta deegaanka: Iyadoo la adkeynayo xeerarka deegaanka, titanium dioxide waxay u baahan tahay inay la qabsato jihada horumarinta ee dahaarka VOC hooseeya iyo kuwa aan sunta ahayn. Isla mar ahaantaana, dahaarka biyaha ku salaysan waxay leeyihiin shuruudo sare oo loogu talagalay xakamaynta cabbirka walxaha iyo tiknoolajiyada daaweynta dusha sare ee titanium dioxide. Bontecn Group China titanium dioxide waxay si buuxda u daboolaysaa baahiyahaaga waxqabadka titanium dioxide. Ku soo dhawoow inaad wax weydiiso.
