Uvavanyo lwe-ether ye-cellulose Indlela ye-BROOKFIELD RVT

I-Brookfield RVT yindlela eqhelekileyo esetyenziswayo yokuvavanya i-viscosity ye-cellulose ethers.I-cellulose ethers ziipolymers ezinyibilikayo emanzini ezisetyenziswa ngokubanzi kwizicelo ezahlukeneyo, kubandakanya amayeza, ukutya, kunye namashishini okhathalelo lomntu.I-viscosity ye-cellulose ethers yiparameter ebalulekileyo echaphazela ukusebenza kwabo kwiindlela ezahlukeneyo.Indlela ye-Brookfield RVT ilinganisa i-viscosity ye-cellulose ethers ngokumisela ukuxhathisa kwabo ukuhamba phantsi koxinzelelo lwe-shear olusetyenzisiweyo.

Nanga amanyathelo okwenza uvavanyo lwe-Brookfield RVT kwii-ethers ze-cellulose:

1. Ukulungiselela isampuli: Lungiselela isisombululo se-2% se-cellulose ether emanzini.Ukulinganisa umlinganiselo ofunekayo we-cellulose ether kwaye uyongeze kwisitya esinomlinganiselo ofunekayo wamanzi.Xuba isisombululo ngokucokisekileyo usebenzisa i-stirrer magnetic de i-ether cellulose ihlakazwe ngokupheleleyo.
2. Instrument Setup: Cwangcisa isixhobo Brookfield RVT ngokwemiyalelo umenzi.Namathisela i-spindle efanelekileyo kwi-viscometer kwaye ulungise isantya kwisimo esifunwayo.Izicwangciso ezicetyiswayo zokusonta kunye nesantya ziyahluka ngokuxhomekeke kwi-ether ye-cellulose ethile evavanywayo.
3. Ulungelelwaniso: Lungiselela isixhobo usebenzisa ulwelo oluqhelekileyo lwesalathiso.Ukulinganisa kuqinisekisa ukuba isixhobo sisebenza ngokufanelekileyo kwaye sinika ukufundwa kwe-viscosity ngokuchanekileyo.
4. Uvavanyo: Beka isampuli elungiselelwe kumphathi wesampuli kwaye uqale i-viscometer.Faka i-spindle kwisampuli kwaye uyivumele ukuba ilingane imizuzwana ye-30.Rekhoda ukufundwa kokuqala kwi-viscometer display.

Yandisa isantya se-spindle ngokuthe ngcembe, kwaye urekhode ukufundwa kwe-viscosity ngamaxesha aqhelekileyo.Izantya zovavanyo ezicetyiswayo ziyahluka ngokuxhomekeke kwi-ether ye-cellulose ethile evavanywayo, kodwa uluhlu oluqhelekileyo luyi-0.1-100 rpm.Uvavanyo kufuneka luqhutyelwe kude kufike isantya esiphezulu, kwaye inani elaneleyo lokufunda lithathiwe ukumisela iprofayili ye-viscosity yesampuli.

5. Ukubala: Bala i-viscosity ye-ether yeselulosi ngokulinganisa ukufundwa kwe-viscosity ethathwe kwisantya ngasinye.I-viscosity ibonakaliswa kwiiyunithi ze-centipoise (cP).
6. Uhlalutyo: Thelekisa i-viscosity ye-ether ye-cellulose kuluhlu lwe-viscosity ekujoliswe kuyo echazwe kwisicelo esijoliswe kuyo.I-viscosity inokulungiswa ngokutshintsha ukugxila okanye ibakala le-cellulose ether.

Isishwankathelo, indlela ye-Brookfield RVT yindlela ethembekileyo nesetyenziswa ngokubanzi yokuvavanya i-viscosity ye-cellulose ethers.Indlela ilula kakhulu kwaye inokubonelela ngolwazi oluxabisekileyo lokuqulunqa kunye nokuphucula imixube eyahlukeneyo.Kubalulekile ukulandela imiyalelo yomenzi kwaye usebenzise izicwangciso ezifanelekileyo kunye ne-spindle ye-ether ye-cellulose ethile evavanywayo.
