Walxaha ceeriin ee budada cinjirka ee dib loo firdhiyey

Budada cinjirka ah ee dib loo firdhiyey (RDP) waa nooc ka mid ah budada emulsion-ka polymer kaas oo si weyn loogu isticmaalo warshadaha dhismaha ee codsiyada sida xabagta foornada sibidhka ku salaysan, xeryahooda is-beddelka ah, iyo daboolka dibadda iyo hababka dhamaystirka. RDP-yada waxaa lagu sameeyaa buufinta emulsion polymer, kaas oo ah isku dhafka biyaha, monomer ama isku dhafka monomers, surfactant, iyo darooyin kala duwan. Maqaalkan, waxaan kaga hadli doonaa alaabta ceeriin ee sida caadiga ah loo isticmaalo soo saarista RDPs.

1. Monomeers-ka monomers-ka loo isticmaalo soo saarista RDP-yada way kala duwanaan karaan iyadoo ku xidhan sifooyinka la doonayo ee alaabta kama dambaysta ah. Monomers-yada caadiga ah waxaa ka mid ah styrene, butadiene, acrylic acid, methacrylic acid, iyo asalkooda. Styrene-butadiene rubber (SBR) waa doorasho caan ah oo loogu talagalay RDPs sababtoo ah ku dheggan wanaagsan, caabbinta biyaha, iyo adkeysiga.
2. Surfactants Surfactants waxaa loo isticmaalaa soo saarista RDPs si loo dejiyo emulsion-ka loogana hortago xinjirowga ama qulqulka. Surfactants-yada caadiga ah ee loo isticmaalo RDP-yada waxaa ka mid ah anionic, cationic, iyo surfactants nonionic. Surfactants Anionic waa nooca ugu badan ee loo isticmaalo RDP-yada, maadaama ay bixiyaan xasilloonida emulsion-ka wanaagsan iyo la jaanqaadka alaabta sibidhka.
3. Xasijiyeyaasha Xasilinta waxaa loo isticmaalaa si looga hortago walxaha polymer-ka ah ee ku jira emulsion-ka inay isku darsamaan ama isku daraan inta lagu jiro kaydinta iyo gaadiidka. Xasijiyeyaasha caadiga ah ee loo isticmaalo RDPs waxaa ka mid ah alkolada polyvinyl (PVA), hydroxyethyl cellulose (HEC), iyo carboxymethyl cellulose (CMC).
4. Initiators Initiators ayaa loo isticmaalaa in lagu bilaabo falcelinta polymerization ee u dhaxaysa monomers ee ku jira emulsion-ka. Bilaabayaasha caadiga ah ee loo isticmaalo RDP-yada waxaa ka mid ah dib-u-habeeyayaasha, sida potassium persulfate iyo sodium bisulfite, iyo kuwa kulaylaha, sida azobisisobutyronitrile.
5. Wakiilada dhexdhexaadinta wakiilada dhexdhexaadinta ayaa loo isticmaalaa in lagu hagaajiyo pH ee emulsion ilaa heer ku haboon polymerization iyo xasiloonida. Wakiilada dhexdhexaadinta caadiga ah ee loo isticmaalo RDPs waxaa ka mid ah ammonia, sodium hydroxide, iyo potassium hydroxide.
6. Wakiilada isku xirka isku dhafka ah ee isku dhafka ah ayaa loo isticmaalaa in lagu gooyo silsiladaha polymer ee emulsion-ka, taas oo hagaajin karta sifooyinka farsamada iyo caabbinta biyaha ee alaabta ugu dambeysa. Waxyaalaha caadiga ah ee laga isticmaalo RDPs waxaa ka mid ah formaldehyde, melamine, iyo urea.
7. Balaastiijiyeyaasha caagadaha waxaa loo isticmaalaa si loo hagaajiyo dabacsanaanta iyo shaqaynta RDP-yada. Balaastiijiyeyaasha caadiga ah ee loo isticmaalo RDPs waxaa ka mid ah polyetylen glycol (PEG) iyo glycerol.
8. Buuxiyeyaasha buuxinta waxaa lagu daraa RDPs si loo hagaajiyo hantidooda makaanikada oo loo dhimo qiimaha. Buuxiyeyaasha caadiga ah ee loo isticmaalo RDPs waxaa ka mid ah kaalshiyam carbonate, talc, iyo silica.
9. Pigments Pigments ayaa lagu daraa RDPs si ay u bixiyaan midabka iyo hagaajinta bilicda alaabta kama dambaysta ah. Midabka caadiga ah ee loo isticmaalo RDP-yada waxaa ka mid ah titanium dioxide iyo oksijiinta birta.

Gebogebadii, alaabta ceeriin ee loo isticmaalo wax soo saarka RDP-yada way kala duwanaan karaan iyadoo ku xidhan sifooyinka la doonayo ee alaabta kama dambaysta ah. Monomers, Surfactants, stabilizers, initiators, wakiilada dhexdhexaadinta, wakiilada isgoysyada, balaastikada, buuxinta, iyo midabada ayaa dhamaantood sida caadiga ah loo isticmaalaa soo saarida RDPs.
