Hydroxyethyl Methyl Cellulose (MHEC)
Methyl Hydroxyethyl Cellulose(MHEC/HEMC)
CAS:9032-42-2
Hydroxyethyl Methyl Cellulose(HEMC) o loʻo faʻaigoaina foi oMethyl Hydroxyethyl Cellulose(MHEC), a versatile, maualuga-faatinoga cellulose ether faʻaaogaina e pei o le maualuga o le faʻamauina o le vai, faʻamautu, faʻapipiʻi ma le faʻapipiʻiina o ata tifaga i ituaiga o mea fau fale. A maeʻa le faʻaleleia ma le togafitiga, e mafai ona tatou maua oloa o loʻo faʻasalalau i le vai vave, faʻaumi le taimi tatala, anti-sagging, ma isi.

Fa'atonuga vaila'au o le MHEC
MHEC e gaosia eetherifying cellulose masanimavaega methyl ma hydroxyethyl. O nei suiga e faaleleia ai lonavai solubility, viscosity, ma fetauima mea eseese.
Meatotino Autu ole MHEC:
- Suavai Suavai: Solu i totonu o vai vevela ma vai malulu, faia ni vaifofo manino.
- Malosiaga Mafiafia: Tuuina atu le viscosity maualuga ma sili atu le puleaina o le rheology.
- Taofi le Suavai: Puipuia le gau o le vai i sima ma oloa faʻavae gypsum, faʻaleleia le faʻamalolo ma le pipii.
- Non-Ionic Nature: E fetaui ma le tele o vailaʻau, e aofia ai masima ma surfactants.
- Ata-Fai Ata: Fausia ata fetuutuunai ma tumau, aoga i faʻalavalava ma faʻaoga vailaʻau.
- Tulaga vevela: Tete'e i le vevela, fa'afaigofie mo fa'aoga maualuga-vevela.

Tulaga lelei o le Fa'aaogaina o le MHEC
✔ Taofi le Suavai Lelei - Puipuia le faʻamago vave i le fausiaina ma faʻaoga teuteu.
✔ Faʻaleleia le Faʻapipiʻi - Faʻaleleia le malosi faʻapipiʻi i faʻapipiʻi maʻa.
✔ Faʻamautu i luga o le lautele o le pH - E galue lelei i siʻosiʻomaga acidic, neutral, ma alkaline.
✔ Fesoʻotaʻiga Non-Ionic - E galue lelei i masima, surfactants, ma isi polymers.
✔ Faʻaleleia le Rheology ma le Flow Properties - Faʻatagaina le faʻatonutonuina o le viscosity, puipuia le tafe ma le faʻafefe.
