Mmetụta nke iji Hydroxypropyl Methyl Cellulose eme ihe na-ezighi ezi

Banyere usoro ngwa ngwa ọkachamara nke ngwaahịa kemịkalụ nakweere, ọ dị mkpa ịdọta uche na nlebara anya nke onye ọrụ ọ bụla na-arụ ọrụ, n'ihi na nke a bụ isi ihe na-eme mkpebi dị mma na imecha nke ọma nke ọrụ owuwu ọ bụla. Ọ bụrụ na usoro nke ime ya yikarịrị ka ọ ga-emetụta ịdị mma nke ngwaahịa ahụ, dịka ọmụmaatụ, hydroxypropyl methylcellulose, nke na-ewu ewu ugbu a na mpaghara dị iche iche, ka anyị lelee ya ọnụ n'okpuru.

Njide mmiri nke methylcellulose na-adabere na ego mgbakwunye ya, viscosity, urughuru mma na ọnụego mgbasa. N'ozuzu, ọ bụrụ na ego mgbakwunye buru ibu, ịdị mma dị ntakịrị, na viscosity dị ukwuu, ọnụ ọgụgụ njide mmiri dị elu. N'ime ha, ọnụ ọgụgụ nke mgbakwunye na-enwe mmetụta kachasị ukwuu na njide mmiri, na ọkwa nke viscosity adịghị adabere kpọmkwem na ọkwa nke njide mmiri. The mgbasa ọnụego tumadi na-adabere n'ókè nke elu mgbanwe nke cellulose ahụ na urughuru fineness. N'ime cellulose ethers dị n'elu, methyl cellulose na hydroxypropyl methyl cellulose nwere ọnụ ọgụgụ njide mmiri dị elu.

Methylcellulose na-agbaze na mmiri oyi, ọ ga-esikwa ike igbari na mmiri ọkụ. Ihe ngwọta ya na-edozi ahụ kwụsiri ike na pH = 3 ~ 12. Ọ nwere ezigbo ndakọrịta na starch, guar gum, wdg na ọtụtụ surfactants. Mgbe okpomọkụ na-erute okpomọkụ gelation, gelation na-eme.

N'ihe banyere iji hydroxypropyl methylcellulose ziri ezi nke anyị gosipụtara gị n'elu, ọ dị mkpa ịdọta uche na nlebara anya nke onye ọ bụla na-arụ ọrụ, iji hụ na ọ dị mma nke ngwaahịa kemịkal a.
