Introduction to Hydroxypropyl Methyl Cellulose HPMC Hypromellose Methocel

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.

Characteristics and advantages of Hydroxypropyl Methyl Cellulose HPMC Hypromellose Methocel

Solubilità eċċellenti fl-ilma: Jista 'jinħall malajr f'ilma kiesaħ biex jifforma soluzzjoni ċara u stabbli.

Tħaxxin effiċjenti u kapaċità ta 'żamma tal-ilma: Żid il-viskożità tal-materjal, tnaqqas b'mod effettiv l-evaporazzjoni tal-ilma, u ttejjeb l-effiċjenza tax-xogħol.

Stabbiltà tajba: Għandu stabbiltà tajba għall-aċidi, alkali, u melħ, u huwa adattat għal firxa wiesgħa ta 'valuri tal-pH.

Effetti li jiffurmaw il-film u protettivi: Wara t-tnixxif, jifforma film iebsa u trasparenti biex jipproteġi s-sottostrat u jipprevjeni l-penetrazzjoni u l-evaporazzjoni tal-ilma.

Mhux tossiku u mhux irritanti: Għandu bijokompatibilità tajba u huwa adattat għall-oqsma tal-mediċina u l-ikel.

Aġġustabilità: Billi tbiddel il-grad ta 'sostituzzjoni u l-piż molekulari, il-prestazzjoni tagħha tista 'tiġi aġġustata biex tissodisfa rekwiżiti ta' applikazzjoni differenti.
