Thickener waa nooc gaar ah oo lagu daro rheological, shaqadiisa ugu weyn waa in la kordhiyo viscosity ee dareeraha rinjiga, hagaajinta waxqabadka kaydinta, waxqabadka dhismaha iyo saameynta filimka rinjiga ee rinjiga.

Astaamaha dhumucyada kala duwan
1. Dhumuc aan organic ahayn
Inta badan la isticmaalo waa bentonite organic, kaas oo ka kooban montmorillonite.Qaab dhismeedka gaarka ah ee lamellar wuxuu ku siin karaa dahaarka leh pseudoplasticity xoog leh, thixotropy, xasilloonida hakinta iyo lubricity.Mabda'a dhumucdiisu waa in budada ay nuugo biyaha oo bararto si ay u dhumucdo wajiga biyaha, sidaas darteed waxay leedahay ilaalin gaar ah oo biyo ah.
Khasaarooyinku waa: socodka oo liita iyo waxqabadka siman, ma fududa in la kala diro oo lagu daro.
2. Eter cellulose
Inta badan la isticmaalo waahydroxyethyl cellulose(HEC), kaas oo leh hufnaan dhumuc sare leh, laalitaan wanaagsan, kala firdhinta iyo guryaha haynta biyaha, badi ahaan adkaynta wejiga biyaha.
Khasaarooyinku waa: saameeya caabbinta biyaha ee daahan, waxqabadka lidka ku ah caaryada oo aan ku filnayn, iyo waxqabadka heerka liita.
3. Acrylic
Dhumucyada acrylic guud ahaan waxay u qaybsan yihiin laba nooc: dhumucyada alkali-barari kara (ASE) iyo dhumucyada alkali-barari kara (HASE).
Mabda'a dhumucsan ee acrylic acid alkali-barari dhumucda (ASE) waa in la kala saaro karboksylate marka pH lagu hagaajiyo alkaline, si silsiladda kelli waxaa laga fidiyaa a helical ilaa ul iyada oo la mid ah-jinsiga repulsion electrostatic u dhexeeya ions karboksilate. , hagaajinta viscosity ee wejiga aqueous.Dhumucyada noocan oo kale ah ayaa sidoo kale leh hufnaan dhumuc sare leh, pseudoplasticity xooggan iyo ganaax wanaagsan.
Dhumucdiisuna waxay barari kartaa associative alkali (HASE) waxay soo bandhigtaa kooxaha hydrophobic ku salaysan dhumucyada caadiga ah ee alkali-barari kara (ASE).Sidoo kale, marka pH-ga lagu hagaajiyo alkaline, isku-soo-celinta electrostatic-ka ee isku midka ah ee u dhexeeya ions carboxylate waxay sameeyaan silsiladda molecular waxay ka soo baxdaa qaabka helical ilaa qaabka ul, taas oo kordhisa viscosity ee wajiga biyaha;iyo kooxaha hydrophobic ee lagu soo bandhigay silsiladda ugu weyn waxay la xiriiri karaan qaybaha cinjirka si loo kordhiyo viscosity ee wajiga emulsion.
Khasaarooyinku waa: u nugul pH, qulqulka ku filan iyo heerka filimka rinjiga, fududahay in la dhumucdo ka dib.
4. Polyurethane
Dhumucda isku dhafka ah ee polyurethane (HEUR) waa hydrophobically modified ethoxylated polyurethane polymer water-soluble, kaas oo iska leh dhumucda associative non-ionic.Waxay ka kooban tahay saddex qaybood: saldhigga hydrophobic, silsilad hydrophilic iyo saldhigga polyurethane.Saldhigga poliurethane wuxuu ku fidaa xalka rinjiga, iyo silsiladda hydrophilic waa mid degan marxaladda biyaha.Saldhigga hydrophobic wuxuu la xiriiriyaa qaab-dhismeedyada hydrophobic sida qaybaha cinjirka, surfactants, iyo midabada., samaynta qaab-dhismeedka shabakad saddex-cabbir ah, si loo gaaro ujeedada dhumucdooda.
Waxaa lagu gartaa dhumucda wejiga emulsion, socodka aadka u fiican iyo waxqabadka sinnaanta, waxtarka dhumucdiisuna waxay wanaagsan tahay iyo kaydinta viscosity ka badan oo deggan, oo aan lahayn xadka pH;waxayna leedahay faa'iidooyin muuqda oo ku saabsan caabbinta biyaha, dhalaalka, hufnaanta, iwm.
Khasaarooyinku waa: habka dhexdhexaadinta dhexdhexaadka ah iyo midka hooseeya, saameynta ka hortagga dejinta ee budada ma fiicna, saameynta dhumucduna waxay si fudud u saameeyaan kala-baxyada iyo dareerayaasha.
