HPMC viscosity

HPMC (hydroxypropyl methylcellulose) bụ ụdị viscosity modifier, thickener, na stabilizer ejiri n'ọtụtụ ụlọ ọrụ. Ọ bụ ihe na-acha ọcha, enweghị isi, ntụ ntụ na-enweghị ụtọ sitere na cellulose ma jiri ya mee ihe n'ụdị dị iche iche, gụnyere nri, ọgwụ, ihe ịchọ mma, na ngwaahịa mmepụta ihe. HPMC bụ ihe na-abụghị ionic, mmiri-soluble polima nke a na-eji na-amụba viscosity nke aqueous ngwọta. Ọ bụ onye na-emepụta ihe na-arụ ọrụ nke ọma ma jiri ya mee ihe iji melite udidi na nkwụsi ike nke ngwaahịa.

HPMC bụ ngwaahịa bara ụba nke enwere ike iji na ngwa dị iche iche. N'ebe a na-emepụta nri, a na-eji ya eme ka nri, gravies, na ofe sie ike. A na-ejikwa ya na-eme ka emulsions na nkwusioru dị ike, na iji melite udidi na ndụ ndụ nke ngwaahịa. N'ime ụlọ ọrụ na-emepụta ọgwụ, a na-eji ya eme ihe iji melite solubility nke ọgwụ ọjọọ, na-eme ka viscosity nke nkwusioru, na ịkwado emulsions. N'ime ụlọ ọrụ ịchọ mma, a na-eji ude, lotions, na gels na-eme ka ọ dị arọ, na-eme ka ọdịdị na nkwụsi ike nke ngwaahịa dịkwuo mma.

A na-ekpebi viscosity nke ngwọta HPMC site na ịdị arọ molekụla nke polymer, ntinye nke ngwọta, na okpomọkụ. The viscosity nke HPMC ngwọta na-abawanye na-amụba molekul arọ na itinye uche, na mbelata na-amụba okpomọkụ. Enwere ike gbanwee viscosity nke ngwọta HPMC site na ịgbakwunye polymers ma ọ bụ surfactants ndị ọzọ.

HPMC bụ ngwaahịa dị mma ma dị irè nke a na-ejikarị eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche. Ọ naghị egbu egbu, enweghị mgbakasị ahụ, na ọ bụghị ihe nfụkasị ahụ, a kwadoro ya maka iji nri, ọgwụ na ihe ịchọ mma. Ọ dịkwa mma na gburugburu ebe obibi. HPMC bụ ihe magburu onwe thickening gị n'ụlọnga na-eji melite udidi na nkwụsi ike nke ngwaahịa. A na-ejikwa ya na-amụba viscosity nke ngwọta mmiri mmiri, na-eme ka emulsions guzosie ike, na iji melite solubility nke ọgwụ.
