I-Hydroxyethyl Methyl Cellulose (HEMC) yoVavanyo loBubushushu beGel

Ukuvavanya ukushisa kwe-gel ye-Hydroxyethyl Methyl Cellulose (HEMC) kubandakanya ukumisela ubushushu apho isisombululo se-HEMC sifumana i-gelation okanye senze i-gel-like consistency.Le ndawo iyimfuneko kwizicelo ezahlukeneyo, kubandakanywa amayeza, izinto zokuthambisa, nezinto zokwakha.Nantsi indlela onokuluqhuba ngayo uvavanyo lobushushu begel kwiHEMC:

Izinto ezifunekayo:

1. HEMC powder
2. Amanzi adityanisiweyo okanye isinyibilikisi (esifanele isicelo sakho)
3. Umthombo wobushushu (umzekelo, ibhafu yamanzi, ipleyiti eshushu)
4. Ubushushu bokulinganisa
5. Intonga yokuvuselela okanye i-stirrer magnetic
6. Iibhekile okanye izitya zokuxuba

Inkqubo:

1. Lungiselela uthotho lwezisombululo ze-HEMC ezinogxininiso olwahlukeneyo (umzekelo, i-1%, i-2%, i-3%, njl.) emanzini adibeneyo okanye i-solvent oyikhethile.Qinisekisa ukuba i-HEMC powder ihlakazwe ngokucokisekileyo kwi-liquid ukukhusela i-clumping.
2. Beka esinye sezisombululo kwi-beaker okanye kwi-container, kwaye ucwilise i-thermometer kwisisombululo sokuhlola ubushushu.
3. Fudumeza isisombululo ngokuthe ngcembe usebenzisa ibhafu yamanzi okanye ipleyiti eshushu ngelixa uvuselela ngokuqhubekayo ukuqinisekisa ukufudumeza okufanayo kunye nokuxuba.
4. Ukubeka iliso kwisisombululo ngokusondeleyo kwaye uqaphele naluphi na utshintsho kwi-viscosity okanye ukuhambelana njengoko ubushushu bukhula.
5. Rekhoda iqondo lokushisa apho isisombululo siqala ukujiya okanye senze i-gel-efana ne-consistency.Eli qondo lokushisa liyaziwa ngokuba yi-gel okanye ukushisa kwe-gelation yesisombululo se-HEMC.
6. Phinda inkqubo yoxinaniso ngalunye lwesisombululo se-HEMC ukumisela ubushushu be-gel kuluhlu lwezigxina.
7. Hlalutya idatha ukuchonga nayiphi na intsingiselo okanye ulungelelwaniso phakathi koxinzelelo lwe-HEMC kunye nobushushu bejeli.
8. Ngokuzikhethela, yenza iimvavanyo ezongezelelweyo okanye iimvavanyo zokuvavanya umphumo wezinto ezifana ne-pH, i-concentration yetyuwa, okanye izongezo kwiqondo lokushisa kwe-gel ye-HEMC.

Iingcebiso:

• Qinisekisa ukuba i-HEMC powder ihlakazwe ngokupheleleyo kwi-liquid ukukhusela i-clumping okanye i-gelation engalinganiyo.
• Sebenzisa amanzi adibeneyo okanye i-solvent efanelekileyo ukulungiselela izisombululo ze-HEMC ukuze ugweme ukuphazamiseka kwizinto ezingcolileyo okanye ezingcolileyo.
• Gxuma isisombululo ngokuqhubekayo ngexesha lokufudumala ukugcina ukusabalalisa ukushisa okufanayo kunye nokuxuba.
• Thatha imilinganiselo emininzi kwaye ulinganise iziphumo ukuphucula ukuchaneka nokuthembeka.
• Qwalasela iimfuno ezithile zesicelo sakho xa ukhetha ugxininiso lweHEMC kunye neemeko zovavanyo.

Ngokulandela le nkqubo, unokumisela ubushushu bejeli ye-Hydroxyethyl Methyl Cellulose (HEMC) izisombululo kwaye ufumane ukuqonda okubalulekileyo kwiimpawu zayo ze-rheological kunye nokuziphatha phantsi kweemeko ezahlukeneyo.
