Ngā āhuatanga hua o te hydroxypropyl methylcellulose mō te hanga

Ka wairewa ki te wai, ā, ka taea te wairewa i ētahi whakarewa waro ki te wai matao, ko tōna kukū mōrahi ka whakatauhia anake e te matotoru, ka rerekē te wairewatanga me te matotoru, ka iti ake te matotoru, ka nui ake te wairewatanga.

Ātete tote: Ko te hydroxypropyl methylcellulose mō te hanganga he ether cellulose kore-ionic, ehara i te polyelectrolyte, nō reira he pumau i roto i te wai wai ina he tote whakarewa, he electrolytes waro rānei, engari ko te tāpiri nui o ngā electrolytes ka puta he piripiri me te ua.

Te ngohe o te mata: nā te mahi mata o te wairewa, ka taea te whakamahi hei kaihoko tiaki colloidal, hei emulsifier me hei dispersant.

Ina werahia ki tētahi pāmahana, ka memeha haere te wairewa wai o te hydroxypropyl methylcellulose hei hanga i te wairewa wera, ka kirikiri, ka pupū ake, engari ina whakamatao tonutia, ka hoki anō ki te āhua wairewa taketake, ā, ka puta tēnei whakapūpū. Ko te pāmahana o te kāpia me te pūpū e whakawhirinaki ana ki ō rātou hinu whakahinuhinu, ngā kaihoko whakatārewatanga, ngā colloid tiaki, ngā emulsifier, me ētahi atu.

Ngā Āhuatanga o te Hua

Ārai-haehae: He pai te kaha ki te ārai-haehae, ā, he pai te pumau o te matotoru i te wā e rokiroki ana mō te wā roa.

Te pumau o te PH: Kāore te waikawa, te kawakore rānei e pāngia e te matotoru o te wairewa wai hydroxypropyl methylcellulose mō te hanga, ā, he pumau te uara pH i waenga i te 3.0 ki te 11.0. Te mau tonu o te āhua Nā te mea he āhuatanga viscoelastic motuhake te wairewa wai tino kukū o te hydroxypropyl methylcellulose mō te hanga ki te whakataurite ki ngā wairewa wai o ētahi atu polymer, ka taea e tōna tāpiri te whakapai ake i te kaha ki te pupuri i te āhua o ngā hua uku kua whakaputahia.

Pupuri wai: he pai te āhua o te hydroxypropyl methylcellulose mō te hanga, ā, he matotoru teitei hoki o tōna wairewa, he tino whai hua te pupuri wai.

Ngā āhuatanga kē atu: te whakamātotoru, te kaihanga kiriata, te here, te hinu whakahinuhinu, te kaihoko whakatārewatanga, te colloid tiaki, te emulsifier, me ētahi atu.
