Ngā Ngota: E whakamārama ana a C2H6O2 xCH4O x PhEur 2002 i te hydroxyethylmethylcellulose hei cellulose O-methylated wāhanga, O-hydroxymethylated wāhanga. Ko ngā whakatakotoranga rerekē e whakaatuhia ana i roto i ngā tikanga o te matotoru kitea i roto i te mPa s o te otinga wai 2% w/v i te 20°C.
Taumaha ngota: E whakamārama ana a PhEur 2002 i te hydroxyethylmethylcellulose hei cellulose O-methylated wāhanga, O-hydroxymethylated wāhanga. Ko ngā whakatakotoranga rerekē e whakaatuhia ana i roto i ngā tikanga o te matotoru kitea i roto i te mPa s o te otinga wai 2% w/v i te 20°C.

Ko ngā āhuatanga matua o te hydroxyethyl methyl cellulose (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. Ngā mahi mata: I te mea he mahi mata te otinga wai, ka taea te whakamahi hei kaihoko tiaki colloid, hei emulsifier me hei dispersant.

4. Heri wera: Ina whakamahanatia te wai hua HEMC ki tētahi pāmahana, ka pōuriuri, ka kirikiri, ka hanga he wairewa, engari ina whakamatao tonutia, ka hoki ki te āhua wairewa taketake, ā, ka puta tēnei kirikiri me te wairewa. Ko te pāmahana e whakawhirinaki ana ki ō rātou hinu whakahinuhinu, ngā āwhina whakatārewatanga, ngā colloid 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: Te matotoru oHEMCKāore te waikawa, te kawakore rānei e pāngia e te wairewa hua, ā, he pumau te pH i waenga i te 3.0-11.0.

Te Whakamahinga: Ka taea te whakamahi i te Hydroxyethyl methyl cellulose hei kaiāwhina tiaki colloid, hei emulsifier me hei dispersant nā te mahi mata o te wairewa. Ko tētahi tauira o tōna whakamahinga penei: Te pānga o te hydroxyethyl methyl cellulose ki ngā āhuatanga o te sima. Ko te Hydroxyethyl methylcellulose 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 emulsifying, te hanga kiriata, te whakatārewa, te mimiti, te whakapūmau, te mata-kaha, te pupuri makuku me te tiaki i ngā colloid. Nā te mahi mata-kaha 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.
