Introduzzjoni għal Hydroxypropyl Methyl Cellulose HPMC

Hydroxypropyl Methylcellulose (HPMC), li l-isem Ċiniż tiegħu huwa hydroxypropyl methylcellulose, huwa semi-sintetiku, etere taċ-ċelluloża mhux joniku miksub billi timmodifika kimikament iċ-ċelluloża naturali. Dan it-trab abjad jista 'jifforma soluzzjoni viskuża trasparenti wara li jinħall fl-ilma. Għandu tħaxxin eċċellenti, żamma tal-ilma, stabbiltà u proprjetajiet li jiffurmaw il-film. Huwa addittiv multifunzjonali indispensabbli f'ħafna oqsma bħall-kostruzzjoni.

Speċifikazzjonijiet ta 'Hydroxypropyl Methyl Cellulose HPMC

Idrossipropil Metil Ċelluloża (HPMC) Rekwiżiti

Dehra u Tip Fiżiku

HPMC appears as a white or somewhat off-white, trab li jiċċirkola ħieles. It has no noticeable odor and feels smooth to the touch. The powder does not clump under normal storage space problems.

Solubilità

HPMC liquifies easily in chilly water to create a clear, soluzzjoni ħoxna. Ma jinħallx fl-ilma sħun, alkoħol, or most organic solvents. When mixed with cool water, it swells initially and afterwards gradually liquifies without developing swellings if effectively spread.

Viskożità

Thickness varies based on grade. Usual viscosity arrays include 5 mPa · s biex 100,000 mPa · s at a 2% tiffoka u 20 ° C. Each set is tested to guarantee it meets the stated thickness variety. Higher viscosity qualities give thicker remedies and far better film-forming capability.

Livelli Alternattivi

HPMC contains 2 crucial substituents: methoxy and hydroxypropoxy groups. Common methoxy web content ranges from 19% biex 30%. Hydroxypropoxy content generally falls in between 4% u 12%. These worths figure out how the item behaves in various applications.

pH Worth

A 2% soluzzjoni likwida ta 'HPMC għandha pH bejniethom 5.0 u 8.0. This neutral-to-slightly-alkaline variety makes it suitable with many other active ingredients made use of in building, farmaċewtiċi, u l-ikel.

Kontenut ta' Umdità

The dampness degree in HPMC is maintained below 5% bil-piż. Low dampness makes sure good flowability and long service life when stored in a completely dry area.

Kontenut Irmied

After incineration, the residue (irmied) stays listed below 5%. This suggests high pureness and marginal not natural impurities.

Dimensjoni tal-Framment

Most HPMC powders travel through a 40-mesh filter. Great grades might go through an 80-mesh or 100-mesh screen for smoother dispersion in sensitive applications.

Żomm f'moħħok: All specs undergo variant based on production standards and customer requirements. Constantly describe the certification of analysis for the specific batch being used.
