Ngwa ngwa nke HPMC
Hydroxypropyl methyl cellulose (HPMC) bụ ụdị na-abụghị ionic cellulose ether, nke e mere nke eke polymer ihe dị ka akụrụngwa na nụchaa site a usoro nke chemical usoro. Taa, anyị ga-amụta banyere arụmọrụ ngwa nke HPMC.
● Mmiri solubility: ọ nwere ike agbaze na mmiri n'ụzọ ọ bụla, ihe kachasị elu na-adabere na viscosity, na mgbasa adịghị emetụta PH.l Organic solubility: HPMC nwere ike gbazere na ụfọdụ ihe mgbaze organic ma ọ bụ ihe mgbaze mmiri mmiri dị ka dichloroethane, ethanol ngwọta, wdg.
● Njirimara gel nke thermal: Gel na-atụgharị ga-apụta mgbe a na-ekpo ọkụ mmiri mmiri ha na-ekpo ọkụ na ụfọdụ okpomọkụ, na-arụ ọrụ nhazi ngwa ngwa.
● Enweghị ụgwọ ionic: HPMC bụ ihe na-abụghị ionic cellulose ether na ọ gaghị eji ion metal ma ọ bụ organics mee ka ọ pụta ìhè.
● Ọkpụkpụ: Usoro ihe ngwọta ya na-eme ka mmiri na-esiwanye ike, na mmetụta nke na-esi na ya na-ejikọta ya na viscosity, ntinye uche, na usoro ya.
● Njide mmiri: HPMC ma ọ bụ ihe ngwọta ya nwere ike ịmịkọrọ ma jide mmiri.
● Nhazi ihe nkiri: Enwere ike ịme HPMC ka ọ bụrụ ihe nkiri dị nro, siri ike na nke na-agbanwe agbanwe, ma nwee ezigbo griiz na oxidation resistance.
● Enzyme Nguzogide: Ihe ngwọta HPMC nwere ezigbo nguzogide enzyme na ezigbo nkwụsi ike.
● Nkwụsi ike PH: HPMC kwụsiri ike na acid na alkali, yana pH adịghị emetụta n'ogo 3-11. (10) Ọrụ elu: HPMC na-enye ọrụ elu na ngwọta iji nweta emulsification achọrọ na mmetụta colloid nchebe.
● Anti-sagging onwunwe: HPMC na-agbakwụnye usoro thixotropic Njirimara na putty ntụ ntụ, ngwa agha, tile gluu, na ndị ọzọ ngwaahịa, na nwere magburu onwe mgbochi sagging ikike.
● Mgbasa: HPMC nwere ike ibelata esemokwu ihu dị n'etiti akụkụ ahụ wee mee ka usoro ahụ gbasasịrị agbasasịa n'otu n'otu n'ime ụmụ irighiri mmiri nke nha kwesịrị ekwesị.
● Adhesion: Enwere ike iji ya dị ka ihe nkedo maka njupụta pigmenti: 370-380g / l³ akwụkwọ, a pụkwara iji ya mee ihe na mkpuchi na ihe mkpuchi.
● Mmanu mmanu: Enwere ike iji ya mee ihe na rọba, asbestos, ciment, na ceramic ngwaahịa iji belata esemokwu ma melite ikike nke kọnkịtị.
● nkwusioru: Ọ nwere ike igbochi ụmụ irighiri ihe ndị a kapịrị ọnụ site na mmiri ozuzo ma gbochie nhazi nke mmiri ozuzo.
● Emulsification: Ebe ọ bụ na ọ nwere ike ibelata elu na esemokwu n'etiti ihu, ọ nwere ike ime ka emulsion kwụsie ike.
● Colloid nchekwa: A na-emepụta oyi akwa mkpuchi n'elu ụmụ irighiri mmiri ndị a chụsasịrị iji gbochie ụmụ irighiri mmiri na-agbakọta ma na-agbakọta iji nweta mmetụta nchebe kwụsiri ike.
