Umahluko phakathi kwe-HPMC kunye ne-MHEC

Umahluko phakathi kwe-HPMC kunye ne-MHEC

I-HPMC (i-Hydroxypropyl Methylcellulose) kunye ne-MHEC (i-Methylhydroxyethylcellulose) zimbini iintlobo ze-cellulose derivatives ezisetyenziswa kwiinkqubo ezahlukeneyo. Zombini zizinto ezisekwe kwiipolymers ezisetyenziselwa ukujiya, ukubopha kunye nokuzinzisa iimveliso. Zombini zisetyenziswa ngokubanzi kumashishini okutya, amayeza, kunye nezokuthambisa.

Umahluko omkhulu phakathi kwe-HPMC kunye ne-Mhec luhlobo lweselulosi esetyenziswayo ukuzenza. I-HPMC yenziwe nge-hydroxypropyl methylcellulose, ngelixa i-Mhec yenziwe nge-methylhydroxyethylcellulose. I-HPMC luhlobo olusulungekileyo kakhulu lweselulosi, ngelixa iMhec iluhlobo olungacocwanga kakhulu.

I-HPMC ngumgubo omhlophe, ongenavumba, kwaye ongenancasa onyibilikayo emanzini abandayo. Isetyenziswa njenge-ejenti yokuqina, i-emulsifier, i-stabilizer, kunye ne-arhente yokumisa kwiimveliso ezahlukeneyo. Ikwasetyenziselwa ukwandisa i-viscosity yezisombululo kunye nokuphucula ukuthungwa kweemveliso. Idla ngokusetyenziswa kwiimveliso zokutya ezifana ne-ayisikrimu, iisosi, kunye nelokhwe.

Kwelinye icala, iMhec ngumgubo omhlophe, ongenavumba nongenancasa nonyibilika kumanzi ashushu nabandayo. Isetyenziswa njenge-ejenti yokuqina, i-emulsifier, i-stabilizer, kunye ne-arhente yokumisa kwiimveliso ezahlukeneyo. Ikwasetyenziselwa ukwandisa i-viscosity yezisombululo kunye nokuphucula ukuthungwa kweemveliso. Idla ngokusetyenziswa kwiimveliso zokutya ezifana ne-ayisikrimu, iisosi, kunye nelokhwe.

Ngokubhekiselele ekusebenzeni, i-HPMC ithathwa njengesebenza ngakumbi kunoMhec. Izinzile kwaye ine-viscosity ephezulu kuneMhec. Ikwamelana ngakumbi notshintsho kwiqondo lobushushu kunye ne-pH. Ukongeza, i-HPMC inobomi obude kune-Mhec.

Ngokwendleko, i-HPMC ibiza kakhulu kuneMhec. Oku kungenxa yokuba i-HPMC luhlobo olusulungekiswe kakhulu lweselulosi kwaye ke kubiza kakhulu ukuvelisa.

Lilonke, i-HPMC kunye neMhec zombini zisetyenziswa ngokubanzi kumashishini okutya, amayeza, kunye nakwezokuthambisa. Zombini zisetyenziswa njengee-agent ezityebisayo, ii-emulsifiers, izizinzisi, kunye nee-agent zokuxhoma kwiimveliso ezahlukeneyo. I-HPMC ithathwa njengesebenza ngakumbi kuneMhec, kodwa ikwabiza kakhulu.
