Sericite

Sericite waa macdan silicate ah oo leh qaab dhismeed miisaan leh.Waxay leedahay qaybo yaryar iyo fuuqbax fudud.Waxaa jira beddelka cation ka yar ee dhismaha.Qadarka K+ ee ka buuxsamay interlayer ayaa ka yar kan muscovite, sidaas darteed maadada potassium ee ka kooban kiimikada ayaa wax yar ka hooseysa tan muscovite.Laakiin biyaha ku jira ayaa ka sarreeya kan muscovite, sidaas darteed dadka qaarkiis waxay ugu yeeraan polysilicon, potassium-poor, mica dhoobada biyaha leh.

Codsiga sericite ee berrinka dahaarka

Superfine sericite budada waa nooc cusub oo buuxinta shaqaynaysa, kaas oo si weyn loogu isticmaalo goobta rinjiga iyo dahaarka.Sababtoo ah budada sericite waxay leedahay qaab miisaan fiican, dusha crystal siman, saamiga weyn ee dhexroor-ilaa dhumucdiisuna, caddaan sare, guryaha kiimikada deggan, miisaanka fudud, siman, dahaarka iyo caabbinta shucaaca, waxaa si ballaaran loo isticmaalaa in rinji-fasalka sare kala duwan, miridhku- dahaarka caddaynta, dab-demiska iyo dahaarka ka-hortagga daxalka.buuxinta midabka wanaagsan.Sababtoo ah qaabka lakabka ah ee sericite, filimka rinjiga ayaa la hayn karaa wakhti dheer iyada oo aan la lumin ka dib marka qaybaha dheeha ay galaan lakabyada lakabka ee sericite.

Dabeecadda kiimikada ee sericite waxay la mid tahay tan buuxinta daahan dhaqameed sida talc, kaolin, wollastonite, iwm, oo labaduba waxay ka tirsan yihiin macdanta silicate, laakiin qaab-dhismeedkeeda gaarka ah iyo guryaha gaarka ah waxay saameeyaan sifooyinka ku habboon ee daahan ee codsiyada, waayo, tusaale ahaan, in Waxay leedahay saamayn tayaynta diyaarad ee rinjiga.Isticmaalka budada sericite ee superfine si aad u bedesho filiyeyaasha caadiga ah ee dabiiciga ah ee qaababka daahan waxay si weyn u wanaajin kartaa xoogga filimka daahan iyo isku dhejinta u dhexeeya filimka daahan iyo substrate-ka, hagaajinta daacadnimada, caabbinta cimilada, caabbinta acid iyo alkali ee daahan, iyo hagaajinta jilicsanaanta filimka rinjiga.Codsaday daahan derbiga dibadda, waxay hagaajin kartaa caabbinta kulaylka, anti-fouling, anti-radiation iyo sifooyinka kale.

Budada sericite-qoyan ee qoyan waxaa lagu dari karaa rinji heer sare ah si loogu beddelo budada zinc, budada aluminium, budada titanium, iwm.Caanaha dufanka leh iyo caanaha akril iyo rinjiga kale ee gidaarka, iyo sidoo kale baabuurta, mooto, rinjiga markabka, iwm.

Ka dib markii lagu daro budada sericite superfine qaab dhismeedka birta daahan dab-damis ah, sifooyinkeeda la xidhiidha si weyn ayaa loo hagaajiyay.Ku darista budada sericite ee ay hagaajisay wakiilka isku-xidhka titanate, xadka iska caabbinta kulaylka ee daahan dab-damiska ayaa kordhay 25 ℃, iska caabbinta biyaha Xadka ayaa laga kordhiyey 28h ilaa 47h, iyo xoogga curaarta ayaa laga kordhiyey 0.45MPa ilaa 1.44MPa.

Ku darista qadar ku habboon budada sericite superfine ee daahan beddelka miridhku waxay kor u qaadi kartaa iska caabbinta kulaylka, caabbinta cimilada, caabbinta biyaha, iska caabinta daxalka iyo sifooyinka farsamada dhamaystiran ee filimka daahan.

Ka dib marka lagu daro budada sericite ultra-fine si loo ilaaliyo dahaadhka ka hortagga, qallafsanaanta dusha sare, dabacsanaanta, adhesion iyo saameynta saameynta filimka daahan ayaa la wanaajiyey;Isla mar ahaantaana, waxay bedeli kartaa ama qayb ahaan bedeli kartaa titanium dioxide ee qaabka dahaarka si loo yareeyo kharashyada iyada oo aan saameyn ku yeelan waxqabadka daahan.
