Ko nga ahuatanga hua o te hydroxypropyl methylcellulose mo te hanga

Ko te wairewa i roto i te wai me etahi whakarewa waro ka taea te rewa i roto i te wai makariri, ko tona kukū morahi e whakatauhia ana e te viscosity, ka huri te memehatanga me te viscosity, te iti iho o te viscosity, te nui ake o te whakarewatanga.

Atete tote: Ko te Hydroxypropyl methylcellulose mo te hanga he etera cellulose katoto-kore, ehara i te polyelectrolyte, no reira he tino pumau i roto i te wairewa wai i te wa e noho ana nga tote whakarewa, nga electrolytes waro ranei, engari ko te nui o te taapiri o nga electrolytes ka taea e te tote te kapia me te rerenga.

Mahi mata: e tika ana ki te mahi kaha mata o te wairewa wai, ka taea te whakamahi hei kaihoko tiaki colloidal, emulsifier me te dispersant.

Ina whakamahana ki tetahi pāmahana, ka huri te wairewa wai o te hydroxypropyl methylcellulose mo te hanga waiariki waiariki, he kaera, ka heke, engari ka whakamatao tonu, ka hoki ki te ahua o te otinga taketake, ka puta mai tenei konene. Ko te pāmahana o te kāpia me te rerenga te nuinga ka whakawhirinaki ki o raatau whakahinuhinu, ki te aukati i nga kaihoko, ki nga colloids whakamarumaru, ki nga emulsifiers, etc.

Nga waahanga hua

Anti-koriri: He pai te kaha ki te aukati i te koriri me te pai o te whakapumautanga i roto i te rokiroki mo te wa roa.

PH pūmautanga: Ko te pokey o te wairewa wai hydroxypropyl methylcellulose mo te hanga karekau e pangia e te waikawa, te kawakore ranei, a, ko te uara pH he mea pumau i te awhe o te 3.0 ki te 11.0. Te pupuri i te ahua Na te mea ko te wairewa wai tino kaha o te hydroxypropyl methylcellulose mo te hanga he ahuatanga viscoelastic motuhake ki te whakataurite ki nga wairewa wai o etahi atu waerau, ka taea e tana taapiri te whakapai ake i te kaha ki te pupuri i te ahua o nga hua karameka.

Te pupuri wai: ko te hydroxypropyl methylcellulose mo te hanga he hydrophilicity me te pokey teitei o tana wairewa wai, he kaihoko pupuri wai tino pai.

Ko etahi atu taonga: te whakamaroke, te kaihoko hanga kiriata, te here, te whakahinuhinu, te kaikawe aukati, te colloid tiaki, te emulsifier, etc.
