Hantida Rheological ee Xalka Methyl cellulose

Xalalka Methyl cellulose (MC) waxay soo bandhigaan sifooyin rheological gaar ah kuwaas oo ku xiran arrimo ay ka mid yihiin diiradda, miisaanka kelli, heerkulka, iyo heerka xiirid. Waa kuwan qaar ka mid ah sifooyinka muhiimka ah ee rheological ee xalalka methyl cellulose:

1. Viscosity: Xalalka methyl cellulose waxay caadi ahaan muujiyaan viscosity sare, gaar ahaan heerkul sare iyo heerkul hoose. Viscosity ee xalalka MC waxay ku kala duwanaan kartaa noocyo kala duwan, laga bilaabo xalalka viscosity hooseeya ee u eg biyaha ilaa jel aadka u muuqda oo u eg qalab adag.
2. Pseudoplasticity: Xalalka Methyl cellulose waxay muujinayaan dabeecad been abuur ah, taasoo la macno ah in maangalkoodu hoos u dhaco iyadoo la kordhinayo heerka xiiridda. Marka lagu daro cadaadiska dhogorta, silsiladaha polymer-ka ee dheer ee xalka ayaa isku dhejiya jihada socodka, yaraynta caabbinta qulqulka iyo natiijada dhaqanka khafiifinta xiirta.
3. Thixotropy: Xalalka Methyl cellulose waxay muujinayaan dabeecadda thixotropic, taasoo la micno ah in viscositykoodu hoos u dhaco waqti ka dib marka la eego diiqada joogtada ah. Marka la joojiyo xiiridda, silsiladaha polymer-ka ee xalka ayaa si tartiib tartiib ah ugu soo noqda hanuunintooda random, taasoo keentay soo kabashada viscosity iyo thixotropic hysteresis.
4. Dareenka Heerkulka: Maqnaanshaha xalalka methyl cellulose waxaa saameeya heerkulka, kulaylka sare ayaa guud ahaan keenaya inuu hoos u dhaco viscosity. Si kastaba ha ahaatee, ku tiirsanaanta heerkulka gaarka ah way kala duwanaan kartaa iyadoo ku xiran arrimo ay ka mid yihiin xoojinta iyo miisaanka kelliyada.
5. Qafiifinta xiirid: Xalalka methyl cellulose waxay maraan khafiifinta xiirid, halkaas oo viscosityku hoos u dhaco marka heerka dhogorta uu kordho. Hantidan ayaa si gaar ah faa'iido ugu leh codsiyada sida dahaarka iyo xabagta, halkaas oo xalku u baahan yahay inuu si fudud u qulqulo inta lagu jiro codsiga laakiin la ilaaliyo viscosity marka la joojiyo xiirta.
6. Sameynta Jeelka: Marka la isku uruursado sare ama darajooyin gaar ah oo methyl cellulose ah, xalalku waxay samayn karaan jel marka la qaboojiyo ama lagu daro milix. Geliyeyaashani waxay muujinayaan dabeecad adag, oo leh viscosity sare iyo caabbinta socodka. Samaynta jel waxa loo isticmaalaa codsiyo kala duwan, oo ay ku jiraan dawooyinka, alaabta cuntada, iyo alaabta daryeelka shakhsi ahaaneed.
7. Waafaqsanaanta Wax-ku-darka: Xalalka methyl cellulose waxaa lagu beddeli karaa waxyaabo lagu daro sida cusbada, surfactants, iyo polymers kale si loo beddelo sifooyinka rheological. Waxyaalaha lagu daro waxay saameyn ku yeelan karaan arrimo ay ka mid yihiin viscosity, dhaqanka gelation, iyo xasiloonida, iyadoo ku xiran shuruudaha diyaarinta ee gaarka ah.

Xalalka methyl cellulose waxay muujinayaan dabeecad qalafsan oo rheological ah oo lagu garto viscosity sare, pseudoplasticity, thixotropy, dareenka heerkulka, khafiifinta dhogorta, iyo samaynta jel. Guryahaani waxay ka dhigaan methyl cellulose mid u adeegsan kara codsiyo kala duwan, oo ay ku jiraan dawooyinka, alaabada cuntada, dahaarka, xabagta, iyo walxaha daryeelka shakhsi ahaaneed, halkaasoo xakamaynta saxda ah ee viscosity iyo habdhaqanka socodka ay lagama maarmaan tahay.
