Umahluko phakathi kwe-HPMC vs methylcellulose

I-HPMC (i-Hydroxypropyl methylcellulose) kunye ne-methylcellulose zombini zisetyenziswa ngokuqhelekileyo kumashishini okutya, amayeza, kunye namashishini okunyamekela abantu njengama-thickeners, stabilizers, emulsifiers, and binding agents. Ngelixa babelana ngezinto ezifanayo, kukho umahluko phakathi kwe-HPMC kunye ne-methylcellulose:

1. Ubume beMichiza: Zombini i-HPMC kunye ne-methylcellulose zithathwe kwi-cellulose, i-polysaccharide eyenzeka ngokwemvelo. I-HPMC yi-cellulose elungisiweyo, apho amanye amaqela e-hydroxyl kwi-molecule ye-cellulose athathelwe indawo ngamaqela e-hydroxypropyl. I-Methylcellulose ikwayi-cellulose elungisiweyo, apho amanye amaqela e-hydroxyl kwi-molecule ye-cellulose athatyathelwe indawo ngamaqela e-methyl.
2. Ukunyibilika: I-HPMC inyibilika ngakumbi emanzini kune-methylcellulose, eyenza kube lula ukuyinyibilika kunye nokusetyenziswa kwimixube.
3. I-Viscosity: I-HPMC ine-viscosity ephezulu kune-methylcellulose, oku kuthetha ukuba ineempawu ezingcono zokujiya kwaye inokudala ukuguquguquka okukhulu kwimiqulu.
4. Gelation: I-Methylcellulose inamandla okwenza ijeli xa ishushu kwaye ipholile, ngelixa i-HPMC ingenayo le propati.
5. Iindleko: I-HPMC ibiza kakhulu kune-methylcellulose.

Ngokubanzi, ukhetho phakathi kwe-HPMC kunye ne-methylcellulose luya kuxhomekeka kwisicelo esithile kunye neempawu ezifunwayo zokuqulunqwa. I-HPMC inokukhethwa ngenxa yokunyibilika kwayo kunye nokungaguquguquki okungqindilili, ngelixa i-methylcellulose inokukhethwa ngenxa yokukwazi ukwenza iijeli.
