HPMC ezokwakhiwa

I-Hydroxypropyl methyl cellulose (HPMC) iyi-ether engeyona ionic cellulose etholakala ku-cellulose yemvelo.Isetshenziswa kabanzi ekwakheni njenge-ejenti yokuqina, i-binder, i-dipersant, i-emulsifier, i-ejenti eyenza ifilimu, i-colloid evikelayo, kanye ne-ejenti yokumisa.

I-HPMC iyimpushana emhlophe kuya kokumhlophe, ayinaphunga, ayinambitheki, futhi engenabuthi.Iyancibilika emanzini abandayo futhi yakha isisombululo esicacile, esibonakalayo.Ayincibiliki kuzincibilikisi zemvelo njenge-ethanol, i-acetone, ne-benzene.I-HPMC iyi-anionic polysaccharide eyakhiwe uchungechunge lwamayunithi we-D-glucose axhunywe ngamabhondi e-β-1,4-glycosidic.Ikhiqizwa ukusabela kwe-methyl chloride ne-hydroxypropyl chloride nge-cellulose.

I-HPMC isetshenziswa kabanzi ekwakheni ngenxa yezakhiwo zayo ezinhle kakhulu.Ingasetshenziswa njenge-ejenti yokuqina ukwandisa i-viscosity yezixazululo ezinamanzi futhi ithuthukise ukusebenza kahle kukasimende nodaka.Ingasetshenziswa futhi njengesibophezelo ukwenza ngcono ukunamathela kukasimende nodaka kuma-substrates.I-HPMC ingasetshenziswa futhi njengesisabalalisi ukuze kwehliswe isidingo samanzi sikasimende nodaka futhi kuthuthukiswe ukusebenza kwazo.Ukwengeza, i-HPMC ingasetshenziswa njenge-emulsifier ukuthuthukisa ukuzinza kwezingxube zikasimende nodaka.

I-HPMC ingasetshenziswa futhi njenge-ejenti eyenza ifilimu ukuthuthukisa ukumelana namanzi kukasimende nodaka.Ingasetshenziswa futhi njenge-colloid evikelayo ukuze kuncishiswe ukungezwani okungaphezulu kukasimende nodaka futhi kuthuthukise ukusebenza kwazo.Okokugcina, i-HPMC ingasetshenziswa njenge-ejenti emisiwe ukuthuthukisa ukumiswa kwezingxube zikasimende nodaka.

I-HPMC iyisengezo esisebenzayo nesiguquguqukayo sezinhlelo zokusebenza zokwakha.Kungathuthukisa ukusebenza kukasimende nodaka, kunciphise isidingo sazo samanzi, kuthuthukise ukunamathela kwazo kuma-substrates, futhi kuthuthukise ukumelana kwazo namanzi.Ukwengeza, ingasetshenziswa njenge-emulsifier, i-ejenti eyenza ifilimu, i-colloid evikelayo, ne-ejenti yokumisa okwesikhashana.I-HPMC iyisengezo esongayo nesiphephile esingasetshenziswa ukuthuthukisa ukusebenza kwezingxube zikasimende nodaka.
