1. Doorka titanium dioxide ee dahaarka
Dahaarku waxay inta badan ka kooban yihiin afar qaybood: walxaha filim samaynta, midabada, dareeraha iyo waxyaabaha lagu daro.Midabka ku jira dahaarka ayaa leh awood gaar ah oo qarsoon.Ma dabooli karto oo kaliya midabka asalka ah ee shayga dahaarka leh, laakiin sidoo kale waxay siin kartaa daboolka midab dhalaalaya.Xaqiiji saameynta qurxinta ee iftiinka iyo qurxinta.Isla mar ahaantaana, midabku wuxuu si dhow ula socdaa wakiilka daweynta iyo substrate-ka, oo isku dhafan, waxay kor u qaadi kartaa xoogga farsamada iyo xajinta filimka daahan, ka hortagga dillaaca ama soo dhaca, waxayna kordhin kartaa dhumucda filimka daahan, ka hortagga dhexgalka fallaadhaha ultraviolet ama qoyaan, iyo hagaajinta daahan.Qalabka ka-hortagga gabowga iyo cimri-dhererka filimka ayaa kordhiya nolosha adeegga filimka iyo shayga la ilaaliyo.
Midabka, qadarka midabka cad waa mid aad u weyn, iyo shuruudaha waxqabadka ee daahan ee midabka cad: ① Cadaadis wanaagsan;② Shiidid wanaagsan iyo qoyn;③Cimilada iska caabbinta wanaagsan;④ Degganaanshiyo kiimiko oo wanaagsan;⑤ Xajmiga walxaha yaryar, awoodda qarinta iyo khasaaraha Awood midab sare leh, iftiin wanaagsan iyo dhalaalid.
Titanium dioxide waa nooc ka mid ah midab cad oo si weyn loogu isticmaalo dahaarka.Wax-soo-saarkeedu waxa uu ka badan yahay 70% midabada aan noolaha lahayn, isticmaalkeeduna waxa uu ka dhigan yahay 95.5% wadarta isticmaalka midabada cadcad.Waqtigan xaadirka ah, qiyaastii 60% titanium dioxide-ka adduunka waxaa loo isticmaalaa in lagu sameeyo dahaaryo kala duwan, gaar ahaan rutile titanium dioxide, kuwaas oo intooda badan ay isticmaalaan warshadaha daahan.Rinjiga laga sameeyay dioxide titanium wuxuu leeyahay midabyo dhalaalaya, awood qarsoodi ah oo sareysa, awood madow oo xoog leh, qiyaas yar, iyo noocyo badan.Waxay ilaalinaysaa xasilloonida dhexdhexaadka ah, waxayna kor u qaadi kartaa awoodda farsamada iyo dhejinta filimka rinjiga, ka hortagga dildilaaca, iyo ka hortagga fallaadhaha ultraviolet.Waxay dhex gashaa biyaha waxayna sii dheereysaa nolosha filimka rinjiga.Midabka isku midka ah ee ku dhawaad ​​qaab kasta oo rinjiga qaabka midabka leh waa mid aan ka soocnayn titanium dioxide.
Noocyada kala duwan ee dahaarka ujeedooyin kala duwan waxay leeyihiin shuruudo kala duwan oo loogu talagalay titanium dioxide.Tusaale ahaan, dahaarka budada waxay u baahan yihiin isticmaalka rutile titanium dioxide oo leh kala firdhisanaan wanaagsan.Anatase titanium dioxide waxa uu leeyahay awood yar oo midabaynta iyo firfircoonida sawir kiimikaad.Marka loo isticmaalo daahan budada ah, filimka dahaadhka ah wuxuu u nugul yahay hurdi.Rutile titanium dioxide oo ay soo saarto habka sulfuric acid waxay leedahay faa'iidooyinka qiimaha dhexdhexaadka ah, kala firdhinta wanaagsan, awoodda qarsoon ee wanaagsan iyo midab dhimista, waxayna aad ugu habboon tahay daboolka budada gudaha.Marka lagu daro kala firdhinta wanaagsan, qarinta awooda iyo midabka yaraynta awooda, titanium dioxide ee dahaarka budada dibadda waxay sidoo kale u baahan tahay jawi wanaagsan.Sidaa darteed, budada titanium ee daboolka budada dibadda ah guud ahaan waa titanium dioxide rutile oo ay soo saarto chlorination.
2. Falanqaynta saameynta isbeddelka tayada ugu muhiimsan ee titanium dioxide ee dahaarka
1 caddaan
Titanium dioxide waxa loo isticmaalaa sidii midab cad oo dahaarka ah.Cadaadiskeedu aad buu muhiim u yahay waana mid ka mid ah tilmaamayaasha tayada muhiimka ah ee loo baahan yahay dahaarka.Caddaan liidata ee titanium dioxide ayaa si toos ah u saameyn doonta muuqaalka filimka daahan.Qodobka ugu muhiimsan ee saameeya cadaanka titanium dioxide waa nooca iyo waxa ku jira wasakhda waxyeelada leh, sababtoo ah titanium dioxide aad bay ugu nugul yihiin wasakhda, gaar ahaan rutile titanium dioxide.
Sidaa darteed, xitaa qadar yar oo wasakh ah ayaa saameyn weyn ku yeelan doonta cadaanka titanium dioxide.Cadaadiska titanium dioxide ee ay soo saarto habka chloride ayaa inta badan ka fiican kan ay soo saarto habka sulfuric acid.Tani waa sababta oo ah alaabta ceeriin ee titanium tetrachloride loo isticmaalo soo saarista titanium dioxide ee habka chloride waa la nadiifiyey oo la nadiifiyey, iyo maadada wasakhda ah ayaa ka yar, halka habka sulfuric acid uu isticmaalo Qalabka cayriin waxay leeyihiin waxyaabo wasakh ah oo sarreeya, taas oo awood u leh oo kaliya. in laga saaro iyadoo lagu dhaqo iyo farsamooyinka bleaching.
2 awood qarinaya
Awoodda qarinaysa waa bedka dusha ee shayga dahaarka leh ee centimitir labajibbaaran.Marka si buuxda loo daboolo, isla aagga ayaa rinji.Inta badan awoodda qarinta ee titanium dioxide la isticmaalo, khafiifinta filimka daahan ayaa noqon kara, iyo inta yar ee caddadka loo baahan yahay, Inta yar ee caddadka titanium dioxide loo baahan yahay, haddii awoodda qarinta ee titanium dioxide hoos u dhaco, si ay u gaaro saameyn isku mid ah oo daboolaya, qadarka titanium dioxide loo baahan yahay ayaa kordheysa, kharashka wax soo saarka ayaa kordhin doona, iyo kororka qadarka titanium dioxide wuxuu keeni doonaa titanium dioxide ee dahaarka Way adagtahay in si siman loo kala firdhiyo, isku-darka ayaa dhacaya, kaas oo doona sidoo kale waxay saameeyaan saameynta daboolka ee daahan.
3 iska caabin cimilada
dahaarka waxay u baahan yihiin iska caabin cimilada sare ee titanium dioxide, gaar ahaan dahaarka dusha dibadda, kuwaas oo u baahan iska caabin cimilada sare ama iska caabin cimilo ultra-sare leh.Isticmaalka titanium dioxide oo leh cimilo yar oo iska caabin ah, filimka dahaadhka ah wuxuu yeelan doonaa dhibaatooyin sida qallafsanaanta, midabaynta, caleenta, dildilaaca, iyo diirka.Qaab dhismeedka crystal-ka ee rutile titanium dioxide wuu ka dhagan yahay kan anatase titanium dioxide, iyo dhaqdhaqaaqeeda sawir-kiimeedka waa hooseeyaa.Sidaa darteed, iska caabinta cimiladu aad bay uga sarraysaa kan anatase titanium dioxide.Sidaa darteed, titanium dioxide loo isticmaalo dahaarka asal ahaan waa titanium dioxide rutile.Habka ugu muhiimsan ee lagu hagaajinayo caabbinta cimilada ee titanium dioxide waa in la sameeyo daaweynta dusha aan organic, taas oo ah, in la daboolo hal ama dhowr lakab oo ah oksaydhyada aan organic ama oksaydhyada fuuqbaxa ee dusha sare ee qaybaha titanium dioxide.
4 kala firdhiso
Titanium dioxide waa qaybo ultra-fiican leh oo leh meel gaar ah oo gaar ah iyo tamar sare oo sare.Way fududahay in la isku geeyo qaybaha oo ay adagtahay in si adag loogu kala firdhiyo dahaarka.Kala firdhinta liidata ee titanium dioxide waxay si toos ah u saameyn doontaa astaamaheeda indhaha sida dhimista midabka, qarinta awoodda iyo dhalaalka dusha sare ee dahaarka, iyo sidoo kale waxay saameeyaan xasilloonida kaydinta, dareeraha, heerka, adkaysiga dahaarka, iyo iska caabinta daxalka ee daahan.Guryaha Codsiga sida korantada korantada iyo conductivity waxay sidoo kale saameyn doontaa qiimaha wax soo saarka ee daahan, sababtoo ah isticmaalka tamarta ee shiida iyo hawlaha kala firdhiyey waa sarreeyaa, xisaabinta inta badan isticmaalka tamarta guud ee habka wax soo saarka daahan, iyo khasaaraha qalabka waa weyn. .
Baahida loo qabo titanium dioxide ayaa kor u kacday sanadkan, gaar ahaan titanium dioxide-ka loo isticmaalo warshadaha duulista ee lithium-ion, taas oo wali ku tiirsan wax soo dejinta.Sida hoose ee titanium dioxide, dahaarka waxaa saameeya duufaanta deegaanka, iyo tiro badan oo ganacsiyada yaryar iyo kuwa dhexdhexaadka ah ayaa la xiray.Mustaqbalka, cadadka titanium dioxide ee suuqa dahaarka ayaa sidoo kale hoos u dhici doona.
