Ikole ite HEMC

Ipele ikole HEMC Hydroxyethyl Methyl Cellulose ni a mọ ni Methyl Hydroxyethyl Cellulose(MHEC), o jẹ funfun tabi pa-funfun lulú, odorless ati ailẹgbẹ, tiotuka Ninu mejeeji omi gbona ati omi tutu. Ikole ite HEMC le ṣee Lo bi simenti, gypsum, orombo gelling oluranlowo, omi idaduro oluranlowo, jẹ ẹya o tayọ admixture fun lulú ile elo.

Awọn ẹya ara ẹrọ ọja:

1. Irisi: HEMC jẹ funfun tabi fere funfun lulú; odorless ati ki o lenu.

2. Solubility: Iru H ni HEMC le ti wa ni tituka ni omi ni isalẹ 60 ℃, ati awọn L iru le nikan wa ni tituka ni tutu omi. HEMC jẹ kanna bi HPMC ati pe o jẹ insoluble ni ọpọlọpọ awọn olomi Organic. Lẹhin itọju dada, HEMC tuka sinu omi tutu laisi agglomeration ati ki o tuka laiyara, ṣugbọn o le ni tituka ni kiakia nipa titunṣe iye PH rẹ si 8-10.

3. Iduroṣinṣin iye PH: Itọpa iyipada kekere laarin iwọn 2-12, ati iki ti wa ni ibajẹ ju iwọn yii lọ.

4. Fineness: oṣuwọn kọja ti 80 mesh jẹ 100%; Oṣuwọn kọja ti 100 mesh jẹ ≥99.5%.

5. Eke pato walẹ: 0.27-0.60g / cm3.

6. Awọn jijẹ otutu ni loke 200 ℃, ati awọn ti o bẹrẹ lati iná ni 360 ℃.

7. HEMC ni iwuwo pataki, iduroṣinṣin idaduro, dispersibility, isomọra, moldability, idaduro omi ati awọn abuda miiran.

8. Nitori ọja naa ni ẹgbẹ hydroxyethyl, iwọn otutu gel ti ọja naa de 60-90 ℃. Ni afikun, ẹgbẹ hydroxyethyl ni hydrophilicity giga, eyiti o tun jẹ ki oṣuwọn asopọ ọja dara. Paapa ni igbona ati giga otutu ikole ni ooru, HEMC ni idaduro omi ti o ga ju methyl cellulose ti iki kanna, ati pe idaduro omi ko kere ju 85%.
