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 kore katote engari ehara i te polyelectrolyte, na reira he tino pumau i roto i te wairewa wai i te wa e noho ana nga tote whakarewa, nga electrolytes waro ranei, engari ka nui te taapiri o nga electrolytes ka taea te whakapouri 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.
Ka 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 konutai.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 pa ki te waikawa, ki te kawakawa ranei, a, ko te uara pH he tino pumau i roto 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.
