Waa maxay nooca dhumuc ee loo isticmaalo rinjiga?

Dhumucyada loo isticmaalo rinjiga caadi ahaan waa walax kordhisa viscosity ama dhumucda rinjiga iyada oo aan saameyn ku yeelan sifooyinka kale sida midabka ama wakhtiga qallajinta. Mid ka mid ah noocyada ugu badan ee dhumucyada loo isticmaalo rinjiga waa wax ka beddelka rheology. Wax-ka-beddelayaashani waxay ku shaqeeyaan iyagoo beddelaya habdhaqanka socodka rinjiga, taasoo ka dhigaysa dhumuc iyo xasilloon.

Waxaa jira dhowr nooc oo wax ka beddelka rheology-ga loo isticmaalo qaabaynta rinjiga, mid walbana wuxuu leeyahay sifooyin iyo faa'iidooyin u gaar ah. Qaar ka mid ah wax ka beddelka rheology-ga inta badan la isticmaalo waxaa ka mid ah:

Asal ahaan Cellulose:
Hydroxyethyl cellulose (HEC)
Hydroxypropyl cellulose (HPC)
Methyl cellulose (MC)
Ethyl hydroxyethyl cellulose (EHEC)
Dheecaannada isku xidha:
Biyo-qabsi ahaan wax laga beddelay urethane ethoxylated (HEUR)
Hydrophobically modified emulsion alkali-soluble (HASE)
Hydrophobically modified hydroxyethyl cellulose (HMHEC)
Asiidhyada Polyacrylic acid:
Carbomer
Acrylic acid copolymers
Clay Bentonite:
dhoobada Bentonite waa dhumuc dabiici ah oo laga soo qaatay dambaska foolkaanaha. Waxay ka shaqeysaa sameynta shabakad qaybo ka mid ah oo dabinaysa molecules-ka biyaha, si ay u adkeeyaan rinjiga.
Silica Gel:
Silica jel waa dhumuc ka samaysan synthetic kaas oo ka shaqeeya isagoo nuugaya oo ku dabinaya dareeraha qaab-dhismeedkiisa daloolsan, sidaas darteed buunbuuninayaa rinjiga.
Dhuxusha Polyurethane:
Dhumucyada poliurethane waa polymers synthetic kuwaas oo loo qaabeeyey si ay u bixiyaan sifooyin rheological gaar ah rinjiga.
Xanthan xanjo:
Xanthan xanjo waa dhumuc dabiici ah oo ka soo jeeda halsano ee sonkorta. Waxay samaysaa joogtayn jel oo kale ah marka lagu qaso biyaha, taasoo ka dhigaysa mid ku habboon adkaynta rinjiga.
Wax-ka-beddelayaashan rheology-ga waxaa sida caadiga ah lagu daraa samaynta rinjiga inta lagu jiro habka wax-soo-saarka tiro sax ah si loo gaaro viscosity-ka la rabo iyo sifooyinka socodka. Doorashada dhumucdiisu waxay ku xiran tahay arrimo kala duwan sida nooca rinjiga (tusaale, biyo ku salaysan ama dareere ku salaysan), viscosity la doonayo, habka codsiga, iyo tixgelin deegaanka.

Marka laga soo tago adkaynta rinjiga, wax ka beddelayaasha rheology sidoo kale waxay door muhiim ah ka ciyaaraan ka hortagga hoos u dhaca, hagaajinta burushka, kor u qaadista heerka, iyo xakamaynta qulqulka inta lagu jiro codsiga. doorashada dhumucdiisuna waxay lagama maarmaan u tahay go'aaminta waxqabadka guud iyo sifooyinka codsiga ee rinjiga.
