Titanium dioxide (TiO2) waa wax soo saar kiimiko ah oo muhiim ah, kaas oo leh isticmaalka muhiimka ah ee dahaarka, khadadka, waraaqaha samaynta, caag caag ah, fiber kiimikaad, ceramics iyo warshado kale. Titanium dioxide (magaca Ingiriisi: titanium dioxide) waa midab cad oo ka kooban titanium dioxide (TiO2). Magaca sayniska waa titanium dioxide (titanium dioxide), qaacidada kelli waa TiO2. Waa iskudhis polycrystalline ah oo qaybaheeda si joogto ah loo habeeyey oo leh qaab dhismeed. Cufnaanta qaraabada ee titanium dioxide ayaa ah tan ugu yar. Habka wax-soo-saarka ee dioxide titanium wuxuu leeyahay laba dariiqo: Habka sulfuric acid iyo habka koloriinta.
Tilmaamaha ugu muhiimsan:
1) Cufnaanta qaraabada
Midabka cad ee sida caadiga ah loo isticmaalo ka mid ah, cufnaanta qaraabada ee titanium dioxide waa tan ugu yar. Midabka cad ee tayada isku midka ah, dusha sare ee titanium dioxide waa kan ugu weyn iyo mugga midabku waa kan ugu weyn.
2) Barta dhalaalaysa iyo barta karkarinta
Maadaama nooca anatase uu u beddelo nooc rutile ah oo heerkul sarreeya, barta dhalaalaysa iyo barta karkarinta ee anatase titanium dioxide dhab ahaantii ma jiraan. Kaliya rutile titanium dioxide ayaa leh bar dhalaalaysa iyo barta karkaraya. Meesha dhalaalaysa ee titanium dioxide rutile waa 1850 ° C, barta dhalaalaysa ee hawadu waa (1830 ± 15) ° C, iyo barta dhalaalaysa ee oxygen-hodanka ah waa 1879 ° C. barta dhalaalaysaa waxay la xiriirtaa daahirsanaanta titanium dioxide. . Meesha karkarinaysa ee titanium dioxide rutile waa (3200± 300)°C, titanium dioxide wax yar ayaa kacsan heerkulkan sare.
3) Dielectric joogto ah
Titanium dioxide waxay leedahay sifooyin koronto oo aad u wanaagsan sababtoo ah joogteynta dielectric sare. Marka la go'aaminayo qaar ka mid ah sifooyinka jireed ee titanium dioxide, jihada crystallographic ee crystals titanium dioxide waa in la tixgeliyaa. Joogtada dielectric ee anatase titanium dioxide waa mid hooseeya, kaliya 48.
4) Hab-dhaqanka
Titanium dioxide waxay leedahay sifooyin semiconductor ah, habaynteedu waxay si degdeg ah u korodhaa heerkulka, sidoo kale waxay aad ugu nugul tahay yaraanta ogsijiinta. Qalabka joogtada ah ee dielectric iyo semiconductor ee rutile titanium dioxide ayaa aad muhiim ugu ah warshadaha elektiroonigga ah, guryahan waxaa loo isticmaali karaa in lagu soo saaro qaybaha elektiroonigga ah sida capacitors dhoobada.
5) Adag
Marka loo eego miisaanka adag ee Mohs, titanium dioxide rutile waa 6-6.5, iyo titanium dioxide anatase waa 5.5-6.0. Sidaa darteed, dabar-goynta fiber kiimikaad, nooca anatase waxaa loo isticmaalaa si looga fogaado xirashada godadka spinneret.
6) Hygroscopicity
Inkasta oo titanium dioxide uu yahay hydrophilic, hygroscopicity ma aha mid aad u xoogan, iyo nooca rutile waa ka yar yahay nooca anatase. Hygroscopicity ee titanium dioxide waxay leedahay xiriir gaar ah oo la leh cabbirka bedkiisa. Aagga dusha weyn iyo hygroscopicity sare ayaa sidoo kale la xiriira daaweynta dusha iyo guryaha.
7) Deganaanshaha kulaylka
Titanium dioxide waa shay leh xasilloonida kulaylka wanaagsan.
8) granularity
Qaybinta cabbirka walxaha ee dioxide titanium waa tusm dhamaystiran, kaas oo si dhab ah u saameeya waxqabadka midabada titanium dioxide iyo waxqabadka codsiga alaabta. Sidaa darteed, dooda ku saabsan awoodda daboolida iyo kala firdhinta ayaa si toos ah loo falanqeyn karaa qaybinta xajmiga walxaha.
Qodobbada saameeya qaybinta cabbirka walxaha ee dioxide titanium waa mid adag. Midka koowaad waa cabbirka cabbirka walxaha asalka ah ee hydrolysis. Xakamaynta iyo hagaajinta xaaladaha habsocodka hydrolysis, cabbirka walxaha asalka ah wuxuu ku dhex jiraa xad gaar ah. Midda labaad waa heerkulka calcination. Inta lagu guda jiro calcination ee metatitanic acid, qayb ka maraan muddo isbedel crystal ah iyo muddo koritaanka, iyo heerkulka ku haboon waxaa la xakameeyaa si ay u sameeyaan qayb koritaanka gudahood xadka gaar ah. Talaabada ugu danbeysa waa miirida alaabta. Caadi ahaan, wax ka beddelka mishiinka Raymond iyo hagaajinta xawaaraha falanqeeyayaasha ayaa loo isticmaalaa si loo xakameeyo tayada firirka. Isla mar ahaantaana, waxaa la isticmaali karaa qalab kale oo wax lagu muquuniyo, sida:-xawaaraha sareeyo, jet pulverizer iyo dubbe.
