Kedu ka HPMC si emetụta arụmọrụ nke ngwa agha na okpomọkụ dị iche iche?

Njide mmiri: HPMC, dị ka onye na-ejigide mmiri, nwere ike igbochi oke evaporation na mfu mmiri n'oge usoro ọgwụgwọ. Ihe eji echekwa mmiri a na-eme ka hydration zuru oke nke ciment ma mee ka ike na ịdịte aka nke ngwa agha dịkwuo mma. N'ebe dị elu nke okpomọkụ, njigide mmiri nke HPMC dị mkpa karịsịa iji gbochie ngwa agha ahụ ka ọ ghara ịlafu mmiri ngwa ngwa, si otú ahụ hụ na ngwa ngwa na-arụ ọrụ.

Ịrụ ọrụ: HPMC nwere mmetụta dị ukwuu na ịrụ ọrụ nke ngwa agha. Site na ịnye mmanu mmanu, ọ nwere ike ibelata esemokwu n'etiti ahụ, na-eme ka ọ dị mfe itinye. Nke a na-arụ ọrụ nke ọma na-eme ka usoro ihe owuwu rụọ ọrụ nke ọma.

Belata mbelata na mgbawa: Mbelata na mgbawa bụ ihe ịma aka a na-ahụkarị na ngwa ngwa ngwa, nke na-ebute ịdịte aka na-emetụta. HPMC na-etolite matriks na-agbanwe agbanwe n'ime ngwa agha ahụ, na-ebelata nrụgide dị n'ime ma na-ebelata ihe omume nke mgbawa, si otú ahụ na-emeziwanye ogologo oge nke ngwa agha ahụ.

Mee ka ike mgbanwe dị mma: HPMC na-abawanye ike nke ngwa agha site n'ịgbasi ike matriks na imeziwanye njikọ dị n'etiti ụmụ irighiri ihe. Nke a ga-eme ka ikike iguzogide nrụgide mpụga ma hụ na nkwụsi ike nke ụlọ ahụ dị.

Njirimara okpomọkụ: Mgbakwunye nke HPMC nwere ike ịmepụta ihe dị ọkụ na mbelata ịdị arọ nke 11.76%. Nke a dị elu porosity na-enyere aka na mkpuchi ọkụ ma nwee ike ibelata conductivity nke ihe ahụ ruo 30% ka ị na-ejigide ọkụ ọkụ na-ekpo ọkụ nke ihe dịka 49W mgbe a na-agbanye otu ọkụ ọkụ. Nguzogide na-ekpo ọkụ na-ekpo ọkụ site na panel ahụ dịgasị iche na ọnụ ọgụgụ nke HPMC agbakwunyere, na ọnụ ọgụgụ kachasị elu nke ihe mgbakwunye na-eme ka 32.6% na-abawanye na nkwụsị ọkụ ma e jiri ya tụnyere ngwakọta ntụaka.

Ngwunye ikuku: HPMC nwere ike belata ike elu nke ngwọta mmiri n'ihi ọnụnọ nke alkyl dị iche iche, na-abawanye ọdịnaya gas na mgbasa, na ike siri ike nke ihe nkiri afụ dị elu karịa nke mmiri mmiri dị ọcha, na-eme ka ọ sie ike ịhapụ. . Ngwunye ikuku a nwere ike ibelata ike mgbanwe na ike mkpakọ nke ihe atụ ciment mortar, ma ọ ga-emekwa ka njigide mmiri nke ngwa agha ahụ dịkwuo elu.

Mmetụta okpomọkụ na gelation: Nnyocha egosiwo na nha nha nhata nke HPMC hydrogel na-ebelata site na mmụba okpomọkụ. Okpomọkụ na-enwe mmetụta dị ukwuu na omume ọzịza nke HPMC hydrogel, nke nwere ike imetụta ngwa ngwa ya na okpomọkụ dị iche iche.

Mmetụta nke okpomọkụ na polymer itinye uche na wetting ike: Mgbanwe na okpomọkụ na HPMC itinye uche na-emetụta ike elu erughị ala na wetting ike nke ya aqueous ngwọta. Ka itinye uche nke HPMC na-abawanye, uru nkuku kọntaktị dị ike nke ngwọta na-abawanye, si otú a na-ebelata omume mgbasa nke mbadamba mbadamba Avicel.

HPMC nwere mmetụta dị ịrịba ama na arụmọrụ nke ngwa agha na okpomọkụ dị iche iche, ma nwee ike imezi njigide mmiri nke ngwa agha, melite ọrụ ọrụ, melite nkwụsị mgbape, welie ike njikọ, melite ogologo oge, belata shrinkage na cracks, melite mmiri na-eguzogide na impermeability, melite ifriizi. - mebie nkwụsi ike, wee kwalite ike nkekọ tensile. Àgwà ndị a na-eme ka HPMC bụrụ ihe mgbakwunye dị mkpa iji kwalite ịdịte aka nke ngwa agha.
