Izinzuzo zebanga lezemithi HPMC

I-HPMC i-hydroxypropyl methylcelluloseisibe ngomunye wabasizi abakhulu bemithi ekhaya naphesheya, ngoba i-HPMC inezinzuzo abanye abasizi abangenazo.

1. Ukuncibilika kwamanzi

Iyancibilika emanzini abandayo angaphansi kuka-40 ℃ noma 70% ethanol, futhi empeleni ayincibiliki emanzini ashisayo angaphezu kuka-60 ℃, kodwa ingafakwa i-gel.

2. Inert ngamakhemikhali

I-HPMC iwuhlobo lwe-non-ionic cellulose ether. Isixazululo saso asithwali i-ionic charge futhi asihlangani nosawoti wensimbi noma izinhlanganisela eziphilayo ze-ionic. Ngakho-ke, amanye ama-excipients awaphenduli nawo phakathi nenqubo yokulungiselela.

3. Ukuzinza

Iqinile ku-asidi ne-alkali, futhi ingagcinwa isikhathi eside phakathi kwe-pH 3 ~11, futhi i-viscosity yayo ayinalo ushintsho olusobala. Isixazululo esinamanzi se-HPMC sinomphumela wokunqanda isikhutha futhi singagcina ukuqina okuhle kwe-viscosity ngesikhathi sokugcina isikhathi eside. Ama-excipients ekhemisi asetshenziswaI-HPMCbabe nokuzinza kwekhwalithi engcono kunalabo abasebenzisa izinto ezisizayo zendabuko (njenge-dextrin, isitashi, njll.).

4. Ukulungiswa kwe-viscosity

I-viscosity derivatives ehlukene ye-HPMC ingaxutshwa ngezilinganiso ezahlukene, futhi i-viscosity yayo ingashintsha ngokuvumelana nomthetho othile, futhi inobudlelwane obuhle bomugqa, ngakho-ke ingakhethwa ngokuvumelana nesidingo. 2.5 Inertia ye-Metabolic HPMC ayimuncwa noma igaywe emzimbeni, futhi ayinikezi amakhalori, ngakho-ke iyisakhi esiphephile samalungiselelo okwelapha. .

5. Ezokuphepha

Ngokuvamile kubhekwa kanjaloI-HPMCayiyona into enobuthi futhi ayicunuli.

I-HPMC yezinga lezemithi iwukusetshenziswa okubalulekile okubalulekile ekukhiqizeni amalungiselelo okukhululwa aqhubekayo futhi alawulwayo. Kuyinzuzo yezemithi esekelwa uhulumeni ocwaningweni nasekuthuthukisweni, futhi ihambisana nesiqondiso sentuthuko esisekelwa yinqubomgomo kazwelonke yezimboni. I-HPMC yezinga lezemithi iwumkhiqizo oyinhloko wokukhiqizwa kwamaphilisi ezitshalo ze-HPMC, ebalwa ngaphezu kuka-90% wezinto ezingavuthiwe zamaphilisi ezitshalo ze-HPMC. Amaphilisi ezitshalo akhiqiziwe anezinzuzo zokuphepha nenhlanzeko, ukusetshenziswa okubanzi, akukho bungozi bokusabela okuxhumanisa, kanye nokuzinza okuphezulu, okuhambisana nokulindelwe ngabathengi. Izidingo zokuphepha nokuthuthwa kwendle zokudla nemithi zingenye yezithako ezibalulekile kanye nemikhiqizo ekahle ethatha indawo yamakhepsuli e-gelatin ezilwane.
