Te Hūrooro Metilohiko (MHEC)
Metila Hauwaitoitirīti Hēroro (MHEC/HEMC)
CAS:9032-42-2
Ko te Hydroxyethyl Methyl Cellulose (HEMC) e kiia ana hoki koMetila Hauwaitoitira Hēroro(MHEC), he cellulose ether mahi-teitei, maha ngā whakamahinga, e whakamahia ana hei kaihoko pupuri wai tino whai hua, hei whakaū, hei piripiri me te kaihoko hanga kiriata i roto i ngā momo rauemi hanga. He whānui te whakamahinga o te MHEC/HEMC i roto i ngā tono ahumahi, pērā i te hanga, te hopi horoi, te peita me te paninga, ka taea hoki e mātou te whakarato HEMC e ai ki ngā hiahia o ngā kiritaki. Whai muri i te whakarerekētanga me te maimoatanga mata, ka taea e mātou te tiki i ngā taonga ka tere te marara ki te wai, ka roa ake te wā tuwhera, ka ārai i te totohu, me ētahi atu.

Hanganga Matū o te MHEC
Ka whakaputaina te MHEC ete cellulose taiao e whakapūmau anamengā rōpū methyl me te hydroxyethyl. Ka whakapai ake ēnei whakarerekētanga i tōnate wairewatanga o te wai, te matotorutanga, me te hototahitangame ngā rauemi rerekē.
Ngā Āhuatanga Matua o te MHEC:
- Wairewatanga Wai: Ka wairewa i roto i te wai wera me te wai matao, ka puta he wairewa mārama.
- Te Pūkenga Whakamātotoru: He nui te matotoru me te whakahaere rheology tino pai.
- Pupuri Wai: Ka ārai i te ngaronga wai i roto i ngā hua sima me te gypsum, ka whakapai ake i te pakari me te piri.
- Āhua Kore-Ionic: Hototahi ki te whānuitanga o ngā matū, tae atu ki ngā tote me ngā surfactants.
- Te Pūkenga Hanga Kiriata: Ka waihanga i ngā kiriata ngāwari, pakari hoki, he mea whai hua mō ngā paninga me ngā tono rongoā.
- Pūmautanga Wera: Ātete ki te wera, he pai mō ngā whakamahinga pāmahana tiketike.

Ngā Painga o te Whakamahi i te MHEC
✔ Pai rawa atu te pupuri i te wai – Ārai i te maroke wawe i roto i ngā mahi hanga me ngā mahi whakapaipai.
✔ Te Piringa Whakapai Ake – Ka whakapai ake i te kaha o te piri i roto i ngā piripiri taera me ngā moata.
✔ Pūmau puta noa i te whānuitanga o te pH – Ka mahi whai hua i roto i ngā taiao waikawa, kūpapa, me te kawakore.
✔ Hototahi Kore-Ionic – He pai te mahi tahi me ngā tote, ngā surfactants, me ētahi atu polymers.
✔ Whakapai ake i te Rheology me ngā Āhuatanga Rere – Ka taea te whakahaere i te matotoru, ka ārai i te maturuturu me te totohu.
