HEC waxay leedahay shaqada dhumucda iyo hagaajinta xoogga xajinta ee dahaarka rinjiyada cinjirka ah.
HEC (Hydroxyethyl cellulose) waa polymer biyo-milmi leh oo leh hagaajinta viscosity wanaagsan, ku milma biyaha iyo dareerayaasha organic, waxayna samayn kartaa emulsions deggan biyaha.Waxay leedahay caabbinta halogen heer sare ah, kulaylka iyo caabbinta alkali, iyo xasilloonida kiimikada sare.HEC waxaa loo isticmaalaa in lagu hagaajiyo viscosity ee rinjiga cinjirka ah, xasilinta guryaha formula, ka hortagga agglomeration ee rinjiga cinjirka, hagaajin adhesion, xoogga jilicsanaanta, dabacsanaanta iyo xidhashada caabbinta filimka daahan, taas oo ah qayb farsamo ee horumarinta rinji cinjir tayo sare leh.
Shaqada ugu weyn ee HEC waa in la hagaajiyo sifooyinka farsamada ee daahan.Waxa kale oo loo isticmaali karaa sida wakiilka ka-hortagga sedimentation, ilaalinta ama wakiilka-viscosity.Iyadoo la'aanteed HEC, waxay si wax ku ool ah u kordhin kartaa viscoelasticity ee dahaarka, waxay kordhisaa xoogga jilicsanaanta iyo dabacsanaanta dahaarka, waxayna tirtiraysaa hoos u dhaca iyo dildilaaca filimka.
Hydroxyethyl cellulose waxay siisaa sifooyin daahan oo heer sare ah oo loogu talagalay dahaarka cinjirka, gaar ahaan daaha PVA sare.Marka dahaarka uu qaro weyn yahay, flocculation ma dhici doono.
Hydroxyethyl cellulose waxay leedahay saameyn dhumuc sare leh.Waxay yarayn kartaa qiyaasta, hagaajinta dhaqaalaha caanaha, iyo hagaajinta caabbinta xoqidda ee daahan.
Xalka aqueous ee hydroxyethyl cellulose waa non-Newtonian, iyo sifooyinka xalka waxaa loo yaqaan thixotropy.
Xaaladda taagan, nidaamka dahaarka ayaa weli ah mid adag oo furan ka dib marka alaabta si buuxda loo kala diro.
Xaaladda la shubay, nidaamku wuxuu ilaaliyaa heerka dhexdhexaadka ah ee viscosity, samaynta alaabtu waxay leedahay dareere aad u fiican, oo aan dillaacin.
Buraashka iyo duubka duuban, alaabtu way fududahay in lagu faafiyo substrate-ka.Ku habboon dhismaha.Isla mar ahaantaana, waxay leedahay iska caabin wanaagsan oo qulqulaya.Marka dahaarka la dhammeeyo, viscosity ee nidaamka ayaa isla markiiba dib loo soo celiyaa, dahaarka isla markiiba wuxuu soo saaraa qulqulka qulqulka.
