Hydroxyethylcellulose (HEC) waa nonionic, polymer biyo-milmi leh oo laga soo qaatay cellulose. Sababo la xiriira sifooyinka rheological ee gaarka ah, waxaa caadi ahaan loo isticmaalaa warshado kala duwan oo ay ku jiraan daawooyinka, qurxinta iyo dhismaha. Mid ka mid ah sifooyinka muhiimka ah ee cellulose hydroxyethyl waa viscosity, kaas oo door muhiim ah ka ciyaara go'aaminta waxqabadkiisa codsiyada kala duwan.
Viscosity waa cabbirka caabbinta dareeraha qulqulka. Xaaladda hydroxyethylcellulose, viscosity keeda waxaa saameeya dhowr arrimood, oo ay ku jiraan feejignaanta, heerkulka iyo heerka dhogorta. Fahamka arrimahan ayaa muhiim u ah wanaajinta isticmaalka HEC qaabab kala duwan.
Viscosity of hydroxyethylcellulose si xoog leh waxay ku xiran tahay sida ay u fiirsashada ee xalka. Guud ahaan, marka diirada HEC kordho, viscosity ay sidoo kale kordhisaa. Dabeecadani waa mid ka mid ah xalalka polymer waxaana badanaa lagu sifeeyaa qaabka sharciga awooda kaas oo la xidhiidha viscosity iyo feejignaanta.
Heerkulka ayaa sidoo kale saameyn weyn ku leh viscosity ee xalalka hydroxyethyl cellulose. Inta badan, viscosity hoos ayuu u dhacaa marka heerkulka kordho. Dareenka heerkulkani wuxuu muhiim u yahay codsiyada halka agabku u baahan yahay in lagu sameeyo isbeddel ku yimaadda viscosity, sida xilliga wax soo saarka ama marka la marsado meelo kala duwan.
Heerka xiiridku waa arrin kale oo muhiim ah oo saameeya viscosity of hydroxyethyl cellulose. Heerka jeexjeexa waxa loola jeedaa heerka ay lakabyada dareeraha ee isku xiga u guuraan marka loo eego midba midka kale. Viscosity ee xalalka HEC sida caadiga ah waxay soo bandhigaan dabeecad khafiif ah xiirid, taasoo la micno ah in marka heerka xiiridu kordho, viscosity hoos u dhaco. Gurigani wuxuu faa'iido u leeyahay codsiyada sida dahaarka iyo koollada halkaasoo fududaynta codsiga looga baahan yahay.
Miisaanka molecular ee hydroxyethyl cellulose sidoo kale wuxuu go'aamiyaa viscositykiisa. Miisaanka kellika sare ee HEC-yada waxay u muuqdaan inay leeyihiin viscosions sare marka la eego fiirsashada. Sifadan ayaa muhiim ah marka la dooranayo darajo gaar ah oo HEC ah codsi gaar ah.
Qaababka dawooyinka, hydroxyethylcellulose waxaa caadi ahaan loo isticmaalaa sidii wakiilka dhumuc ee qaababka qiyaasta afka iyo afka. Viscosity ee HEC waxay hubisaa joojinta habboon ee walxaha waxayna bixisaa joogtaynta loo baahan yahay si sahlan loo qiyaaso. Intaa waxaa dheer, habdhaqanka xiirid-xiirashada ee HEC waxay wanaajin kartaa faafinta qaababka jirka la mariyo.
Warshadaha isqurxinta, hydroxyethylcellulose waxaa loo isticmaalaa alaabooyin kala duwan, oo ay ku jiraan shambooyinka, loshinka iyo kiriimyada. Wax-ka-beddelka viscosity-keeda ayaa gacan ka geysta hagaajinta xasilloonida iyo qaab-dhismeedyadan, si kor loogu qaado khibradda isticmaale ee guud.
Warshadaha dhismaha, hydroxyethylcellulose waxaa inta badan loo isticmaalaa dhumuc ahaan alaabta cement-ku salaysan. Viscosity ee HEC waxay gacan ka geysataa xakamaynta socodka iyo socodsiinta walxaha inta lagu jiro codsiga. Tani waxay si gaar ah muhiim ugu tahay codsiyada sida xabagta tile iyo grouts.
Viscosity of hydroxyethyl cellulose waa halbeeg muhiim ah oo saameeya waxqabadkeeda codsiyada kala duwan. Fahamka arrimaha saameeya viscosity-ka, sida feejignaanta, heerkulka, iyo heerka xiirid, ayaa muhiim u ah wanaajinta isticmaalka HEC ee warshado kala duwan. Sida polymer-ka badan, hydroxyethyl cellulose waxay sii wadaa inay door muhiim ah ka ciyaarto hagaajinta waxqabadka badeecadaha kala duwan ee warshadaha kala duwan.
