HydroxyPropyl Methyl Cellulose na Carboxymethyl Sodium ya selile irashobora kuvangwa

Irashobora hpmc na cmc ivanze

Methyl selileni umweru cyangwa yera nka fibrous ifu cyangwa granular ifu; Impumuro nziza, uburyohe. Ibicuruzwa mumazi kubyimba mu gisubizo gisobanutse cyangwa gito cya turbud; SHOREAN NA Ethanol Yuzuye, chloroform cyangwa diathyl ether. Iratatana vuba kandi ibyimba mumazi ashyushye kuri 80-90 ℃, kandi ashonga vuba nyuma yo gukonja. Igisubizo cya akeque kirahagaze neza mubushyuhe bwicyumba, kandi gishobora gufata ubushyuhe bwinshi, kandi gel irashobora guhinduka hamwe nigisubizo cyubushyuhe.

Ifite ubuvuzi buhebuje, gutatanya, kumeneka, kubyimba, kwishyurwa, kugumana amazi no gushinga filimi, kimwe no kudatungana kwamavuta. Filime ifite ubutoni buhebuje, guhinduka no gukorera mu mucyo. Kuberako ntabwo ari ionic, birashobora guhuzwa nabandi kubyerekeranye, ariko biroroshye kumunyu, kandi igisubizo cya seliki, ni ifu ya fibrit ya selile, ni iy'umunyu wera wa sodimir cyangwa amata 0.5-0-0-7 G / Cubic santimeter, hafi impumuro nziza, uburyohe, hygroscopique. Biroroshye gutatanya mumazi muri tradinent celatinous igisubizo, consoluble muri ethanol hamwe nibindi bilime.

Iyo PH yigisubizo gitangaje ari 6.5 - 8.5, viscosiya igabanuka cyane mugihe PH ihagaze neza muri 45 ℃, kandi imikorere yubushyuhe, uruhinja ruramuka rugabanuka cyane mugihe ashyushye hejuru ya 80 ℃. Byoroshye gushonga mumazi, igisubizo kibonerana; Birahamye cyane mu gisubizo cya alkaline, kandi byoroshye kuri hydrolyze murubanza rwa aside. Iyo agaciro PH ari 2-3, imvura izabaho, kandi imvura nayo izamera mugihe cyumunyu mwinshi wicyuma. HydroxyPropyl Methyl Cellulose, uzwi kandi nka HydroxyProppopyl Methyl Methyl, ni uguhitamo ipamba nziza, muburyo bwa alkaline muburyo budasanzwe no kwitegura.

Gushonga mumazi na Polar C kandi ikwiye ya Ethanol / Amazi, Spanonol / Amazi, Amazi, kubyimba mumazi akonje cyangwa akonje gato cyangwa yanduza gato. Igisubizo cyamazi gifite ibikorwa byo hejuru, gukorera mu mucyo bikabije hamwe n'imikorere ihamye.Hpmcifite umutungo wa Gel ashyushye. Nyuma yo gushyushya, ibicuruzwa igisubizo cyibitangaza bigize imvura ya Gel, hanyuma irashonga nyuma yo gukonja. Ubushyuhe bwa Gel BITANDUKANYE buratandukanye.
