Budada midabka ultrafine waxaa inta badan loo qaybiyaa midabada organic iyo midabada aan dabiiciga ahayn, midabada organic waxaa inta badan loo qaybiyaa midabka azo, pigments harooyinka, pigments heterocyclic, pigments ketone giraanta qaro weyn, pigments phthalocyanine iyo midabyo kale. Midabka aan dabiiciga ahayn ayaa inta badan loo qaybiyaa titanium dioxide, carbon black, iron oxide cas, iwm. Midabka dabiiciga ah ama aan dabiiciga ahayn waxay leeyihiin midabyo dhalaalaya, xoog midab leh, midab sare leh iyo hufnaan sare, kuwaas oo buuxiya shuruudaha daboolka iyo daabacaadda khadadka.
Si kastaba ha ahaatee, habka diyaarinta budada pigment, finner size qayb ka, dusha sare ee budada pigment ayaa kordhin doona, taas oo si fudud u horseedi kartaa in ay agglomeration, samaynta qaybo waaweyn, rinjiga iyo nidaamka khad xasiloonida, si dhab ah u saameeya tayada alaabta.
Waqtigan xaadirka ah, qaybinta cusbada ammonium organic ayaa loo baahan yahay in lagu daro habka burburinta midabka, midabka midabka ee nidaamka koollada pigment, inta badan adsorb in ay dusha sare ee budada, la yareeyo tamarta dusha ee qaybaha midabka ultrafine, si loo gaaro saamaynta kala firidhsan uniform. iyo qaybinta cusbada ammonium-ka organic waxay si wax ku ool ah uga hortagi kartaa in timaha midabka sabbaynaya degsiimo aan dhab ahayn. Ku habboonaanta wanaagsan ee rinjiga iyo daabacaadda qalinka si loo horumariyo waxqabadka midabaynta.
Waa maxay sababtaWakiilka kala firdhinta NNOshaqada?
TheWakiilka kala firdhinta NNOmolecule ka kooban yahay koox barroosin ah iyo qayb xasilinta. Doorka kooxda xiritaanku waa in ay bixiyaan xoog ku filan oo ku filan oo ku xiran walxaha buuxinta midabka. Unugyada kala firdhiyaa kama soo dhacaan dusha sare ee walxaha, taas oo shardi u ah kala firdhinta inay shaqeyso. Shaqada qaybta xasilinta waa in la dejiyo qaybaha isku-darka midabka midabka ee ku kala firdhiyey xoogga farsamada iyada oo loo marayo dib-u-celinta elektrostatic iyo caabbinta booska ee marxaladda dareeraha si looga hortago in qaybaha isku-darka.
Qallafiyeyaasha organic, marka qaybta xasilloon ee kala firdhiyahu ay dejiso qaybaha midabka kala firdhiyey ee iska caabin ah, marka kala fogaanshahaWakiilka kala firdhinta NNOQaybaha ayaa ka yar cabbirka silsiladda dareeraha ah, silsiladda dareeraha ah ayaa isku ururisa midba midka kale oo entropy hoos u dhaco. Biyaha dhexdiisa, ionization waxay ku dhacdaa agagaarka kooxaha ionic si ay u sameeyaan lakab labajibbaaran, iyo dib-u-celinta elektrostatic waxay ka hortagtaa qulqulka walxaha. Haddii polyeter-ka aan ionized ahayni uu xasiloon yahay, polyeter-ku waxa uu dejiyaa qaybaha midabada kala firdhiyey ee iska caabbinta meel bannaan.
