Hydroxyethyl Methyl Cellulose (MHEC)
Methyl Hydroxyethyl Cellulose(MHEC/HEMC)
CAS:9032-42-2
Hydroxyethyl Methyl Cellulose(HEMC) kua whakaingoatia anoMethyl Hydroxyethyl Cellulose(MHEC), he maha, he tiketike-mahi cellulose ether whakamahia hei kaihoko pupuri wai tino pai, stabilizer, adhesives me te kaihoko hanga kiriata i roto i te momo o te hanga rauemi. Kei te whakamahia whānuitia MHEC / HEMC i roto i te tono ahumahi ,pērā i te hanga, horoi , peita me te paninga , ka taea hoki e matou te whakarato HEMC kia rite ki nga whakaritenga a nga kaihoko. I muri i te whakarereketanga me te maimoatanga o te mata, ka taea e taatau te tiki i nga taonga kua marara ki roto i te wai tere, kia roa te wa tuwhera, anti-sagging, etc.
āhuatanga angamaheni
| Te ahua | Maama ki te paura ma |
| Te rahi o te matūriki | 98% ki te 100 mata |
| makuku (%) | ≤5.0 |
| Uara PH | 5.0-8.0 |
Hanganga matū o MHEC
Ko te MHEC i hangaia ete whakakoi i te cellulose taiaomenga roopu methyl me te hydroxyethyl. Ko enei whakarereketanga ka whakapai akete wairewa, te pokey, me te hototahime nga rauemi rereke.
Ngā Āhuatanga Matua o MHEC:
- Wairewa Wai: Wairewa i roto i te wai wera me te wai matao, ka hangaia he otinga maamaa.
- Te Maamaa: Ka whakarato i te pokey teitei me te mana whakahaere rheology.
- Te Pupuri Wai: Ka aukati i te mate o te wai i roto i nga hua ciment me nga hua gypsum, hei whakapai ake i te rongoa me te piri.
- Kore-Ionic Nature: Hototahi ki te whānuitanga o nga momo matū, tae atu ki te tote me te surfactants.
- Te Hanga Kiriata: Ka hangaia he kiriata ngawari me te roa, e whai hua ana ki nga paninga me nga tono rongoa.
- Te Pumau Ngaaariki: He atete ki te wera, he pai mo nga tono wera-nui.

Nga Painga o te Whakamahi MHEC
✔ Te Pupuri Wai Pai - Ka aukati i te whakamaroketanga o mua i roto i nga mahi hanga me nga mahi whakapaipai.
✔ Whakanuia te Adhesion - Whakapai ake i te kaha hononga i roto i nga taapiri taera me nga moata.
✔ Puta noa i te Awhe pH whanui – He pai te mahi i roto i nga taiao waikawa, koretake, kawakore hoki.
✔ Hototahi Kore-Katote - He pai te mahi me nga tote, nga hau, me etahi atu waerau.
✔ Whakapai ake i te Rheology me te Rere Ahuatanga - Ka taea te whakahaere i te viscosity, te aukati i te maturuturu me te totohu.
