Hypromellose ma la mid baa HPMC?
Haa, hypromellose wuxuu la mid yahay HPMC (hydroxypropyl methylcellulose). Hypromellose waa magaca caalamiga ah ee aan hantida lahayn (INN) ee alaabtan, halka HPMC uu yahay magaca ganacsiga caadiga ah ee loo isticmaalo warshadaha.
HPMC waa cellulose wax laga beddelay, halkaas oo qaar ka mid ah kooxaha hydroxyl ee ku jira molecule cellulose lagu beddelay hydroxypropyl iyo methyl. Waa caddaan ama cad-cad, aan ur lahayn, iyo budo aan dhadhamin oo ku milma biyaha iyo dareerayaasha organic.
HPMC waxa caadi ahaan loo isticmaalaa sidii dhumuc, xidhe, iyo emulsifier codsiyo kala duwan, oo ay ku jiraan dawooyinka, cuntooyinka, waxyaalaha la isku qurxiyo, iyo alaabta daryeelka shakhsi ahaaneed. Astaanteeda, sida viscosity, solubility, iyo gelation, waxaa lagu hagaajin karaa iyadoo la kala bedelayo heerka beddelka (DS) iyo miisaanka kelli (MW) ee polymerka.
Isticmaalka hypromellose ee dawooyinka ayaa si gaar ah u faafaya sababtoo ah isugeyntiisa iyo nooleheeda. Waxa caadi ahaan loo isticmaalaa sidii kiniinka xidhadhiyaha, kala daadsan, iyo wakiilka sii-deynta joogtada ah, iyo sidoo kale walax dhumuc leh iyo hakinta habaynta dareeraha. Awooddeeda in ay samayso jel marka la eego xaddi badan ayaa sidoo kale ka dhigaysa mid faa'iido u leh codsiyada sii-deynta la kantaroolo.
Hypromellose waxaa sidoo kale loo isticmaalaa warshadaha kale. Tusaale ahaan, waxa loo isticmaali karaa sidii dhumuye, xasiliye, iyo emulsifier ee alaabta cuntada, sida suugada, dhaymada, iyo waxyaabaha caanaha laga sameeyo. Alaabooyinka daryeelka shakhsi ahaaneed, hypromellose waxaa loo isticmaali karaa sidii dhumuc iyo emulsifier ee looshannada, shambooyinka, iyo qaababka kale ee qurxinta.
hypromellose iyo HPMC waxay tixraacaan walxo isku mid ah, taas oo ah polymer la taaban karo oo si ballaaran loo isticmaalo warshadaha kala duwan. Hantideeda iyo shaqeynteeda ayaa lagu hagaajin karaa iyadoo lagu saleynayo codsiga gaarka ah iyo badeecada dhamaadka la rabo.
