Iyadoo horumarinta iyo codsiga rinjiga cinjirka ee biyaha ku salaysan, doorashada dhumucda rinjiga cinjirka ayaa kala duwan.Hagaajinta rheology iyo kontoroolka viscosity ee rinjiga cinjirka ah ee heerar sare, dhexdhexaad iyo hoose.Xulashada iyo adeegsiga dhumucyada rinjiga cinjirka iyo rinjiga cinjirka ee hababka emulsion ee kala duwan (akril saafi ah, styrene-acrylic, iwm.).
Doorka ugu weyn ee dhumucyada rinjiyada cinjirka, kaas oo rheology uu yahay mid ka mid ah qodobbada muhiimka ah ee ka kooban muuqaalka iyo waxqabadka filimada rinjiga.Sidoo kale ka fiirso saamaynta viscosity on roobka midabka, burushability, simaynta, buuxda ee filimka rinjiga, iyo sag of filimka dusha inta lagu guda jiro cadayashada toosan.Kuwani waa arrimo tayo leh oo soosaarayaashu inta badan ku xisaabtamaan.
Halabuurka dahaarka wuxuu saameeyaa rheology ee rinjiga cinjirka, iyo viscosity waxaa lagu hagaajin karaa iyadoo la beddelo diiradda emulsion iyo diiradda walxaha kale ee adag ku kala firdhiyey rinjiga cinjirka.Si kastaba ha ahaatee, kala duwanaanshaha hagaajintu waa xaddidan yahay qiimuhuna waa sarreeyaa.Viscosity ee rinjiga cinjirka waxaa inta badan hagaajiya dhumucyada.Dhumucyada caadiga ah ee la isticmaalo waa: dhumucyada ether cellulose, dhumucyada emulsion polyacrylic acid alkali-barari, dhumucyada polyurethane associative non-ionic, iwm.Qiimaha waxsoosaarku waa weyn yahay.Silsiladda ugu weyn ee hydrophobic ee dhumucda cellulose waxay la xiriirtaa unugyada biyaha ee ku hareeraysan iyada oo loo marayo isku xidhka hydrogen, taas oo kordhisa mugga dareeraha polymer laftiisa.Meesha dhaqdhaqaaqa xorta ah ee walxaha waa la dhimay.Viscosity ee nidaamka waa la kordhiyey, iyo qaab-dhismeedka shabakad isku xiran ayaa la sameeyay inta u dhaxaysa midabka iyo qaybaha emulsion.Si loo kala saaro midabada midba midka kale, qaybaha emulsion-ka ayaa si dhif ah u soo baxa.
