Ngā āhuatanga matua ote hauwaitoireti metireti pūtau (HEMC)ko:
1. Wairewatanga: wairewa i roto i te wai me ētahi whakarewa waro, ka taea te wairewa i te HEMC i roto i te wai matao, ko tōna kukū mōrahi ka whakatauhia anake e te matotoru, ka rerekē te wairewatanga me te matotoru, ko te iti o te matotoru, ko te nui ake o te wairewatanga.
2. Ātete tote: Ko ngā hua HEMC he ether cellulose kore-ionic, ehara i te polyelectrolytes, nō reira i te aroaro o ngā tote whakarewa, o ngā electrolytes waro rānei, he pumau tonu i roto i ngā wairewa wai, engari ko te tāpiri nui o ngā electrolytes ka puta te waikura me te maturuturu.
3. Te ngohe o te mata: Nā te mea he mahi ngohe o te mata te otinga wai, ka taea te whakamahi hei kaihoko tiaki colloid, hei emulsifier me hei dispersant.
4. Te tiēre wera: Ina teHEMCKa whakamahanatia te hua wairewa ki tētahi pāmahana kua whakaritea, ka memeha haere, ka hanga he wairewa, engari ina whakamatao tonutia, ka hoki anō ki te āhua taketake o te wairewa, ā, ka puta te wairewa me te wairewa. Ko te pāmahana e whakawhirinaki ana ki ō rātou hinu whakahinuhinu, ngā āwhina whakatārewatanga, ngā korori tiaki, ngā emulsifier, me ētahi atu.
5. Te koretake o te pākia o te tinana, te iti o te kakara me te haunga: He whānuitia te whakamahinga o te HEMC i roto i te kai me te rongoā nā te mea kāore e pākia, ā, he iti hoki te kakara me te haunga.
6. Ārai harore: He pai te kaha o te HEMC ki te ārai harore, ā, he pai te pumau o te matotoru i te wā e rongoatia ana mō te wā roa.
7. Te pumau o te PH: Kāore te waikawa, te kawakore rānei e pāngia e te matotoru o te wai hua HEMC, ā, he pumau te uara pH i waenga i te 3.0-11.0.
Te tono oTe pūhui hauwaioraitiri metila (HEMC)：
Ka taea te whakamahi i te Hydroxyethyl methyl cellulose hei kaiāwhina tiaki colloid, hei emulsifier me hei dispersant nā te mea he mahi kaha te mata o te wai i roto i te wairewa. Ko tētahi tauira o tana whakamahinga penei: Te pānga o te hydroxyethyl methyl cellulose ki ngā āhuatanga o te sima. Ko te Hydroxyethyl methyl cellulose he paura ma, kāore he kakara, kāore he reka, kāore he paitini e rewa ana ki te wai matao hei hanga i tētahi wairewa mārama, matotoru. Kei a ia ngā āhuatanga o te whakamātotoru, te here, te horapa, te whakaemulsifying, te hanga kiriata, te whakatārewa, te mimiti, te whakapūmau, te whakakaha mata, te pupuri makuku me te tiaki i ngā colloid. Nā te mahi kaha o te mata o te wairewa, ka taea te whakamahi hei kaiāwhina tiaki colloid, hei emulsifier me te dispersant. He pai te hydrophilicity o te wairewa Hydroxyethyl methyl cellulose, ā, he kaiāwhina pupuri wai tino whai hua.
