Kedu ihe bụ mmetụta HPMC na kọmpụta?

Hydroxypropyl methylcellulose (HPMC) bụ polymer soluble mmiri nke a na-eji n'ọtụtụ ngwa dị iche iche, gụnyere dị ka ihe mgbakwunye na kọmpat. HPMC bụ polymer nke dabeere na cellulose nke a na-eji na-emeziwanye ihe nke kọnkịtị, dị ka ịrụ ọrụ, ike, na ogologo oge. A na-ejikwa ya iji belata mmiri mmiri nke ihe na-eme ka ọ dịkwuo elu nke hydration nke ciment.

A mụọla iji HPMC eme ihe n'ọtụtụ ebe wee chọpụta na ọ nwere ọtụtụ uru bara uru. HPMC nwere ike melite workability nke ihe site na ịba ụba nke fluidity na ibelata viscosity nke mix. Nke a na-enye ohere maka mfe ọnyịnye na compacting nke ihe. HPMC na-abawanye ike nke ihe site n'ịba ụba nke hydration nke ciment, nke na-eme ka ihe siri ike ma sie ike. Na mgbakwunye, HPMC nwere ike ibelata ọdịnaya mmiri nke kọnkịrị, nke nwere ike inye aka belata oke mbelata nke na-eme n'oge usoro ọgwụgwọ.

Ojiji nke HPMC na ihe nwekwara ike melite anwụ ngwa ngwa nke ihe. HPMC nwere ike ibelata permeability nke ihe, nke nwere ike inye aka belata ego nke mmiri na mmiri ndị ọzọ nwere ike banye n'ime ihe. Nke a nwere ike inye aka belata ọnụ ọgụgụ mmebi nke nwere ike ime n'ihi cycles na-ekpo ọkụ, mwakpo kemịkal, na ihe ndị ọzọ metụtara gburugburu ebe obibi. Ọzọkwa, HPMC nwere ike ibelata uzuzu uzuzu nke nwere ike ime n'elu kọmpụta, nke nwere ike inye aka belata nhazi nke achọrọ.

N'ozuzu, iji HPMC na ihe nwere ike inye ọtụtụ uru bara uru. HPMC nwere ike imeziwanye ọrụ nke kọmpụta, mee ka ike nke ihe ahụ dịkwuo ike, belata ọdịnaya mmiri nke ihe ahụ, ma mee ka ọ dịkwuo ogologo oge. Mmetụta ndị a nwere ike inye aka mee ka mma nke ihe ahụ dị mma ma belata nhazi nke a chọrọ.
