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 o ni iwuwo pataki, iduroṣinṣin idadoro, 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%.

Bi awọn kan dada ti nṣiṣe lọwọ oluranlowo, hydroxyethyl methyl cellulose HEMC ni o ni awọn wọnyi abuda ni afikun si nipon, suspending, imora, emulsifying, film-forming, dispersing, omi-idaduro ati ki o pese aabo colloid:

(1) Hydroxyethyl methyl cellulose HEMC jẹ tiotuka ninu omi gbigbona tabi tutu, ti o jẹ ki o ni ibiti o pọju ti solubility ati awọn abuda viscosity, eyini ni, gelation ti kii-gbona;

(2) Hydroxyethyl methyl cellulose HEMC le ṣe ibagbepọ pẹlu ọpọlọpọ awọn polima ti omi-tiotuka miiran, awọn surfactants, ati awọn iyọ, ati pe o jẹ ohun ti o nipọn ti o dara julọ fun awọn solusan elekitiroti ti o ga julọ;

(3) HEMC ni idaduro omi ti o lagbara ju methyl cellulose, ati iduroṣinṣin viscosity rẹ, dispersibility, ati imuwodu imuwodu ni okun sii ju ti hydroxyethyl cellulose.
