Mapuloteni a Hydroxyethyl methyl

Hydroxyethyl methyl cellulose (HEMC) idakonzedwa poyambitsa ethylene oxide m'malo mwa methyl cellulose (MC). Kulekerera kwake mchere kunali bwino kusiyana ndi polymer yopanda mawonekedwe, ndipo kutentha kwa gel kwa methyl hydroxyethyl cellulose kunali kokulirapo kuposa methyl cellulose.

Katundu

1. Maonekedwe: Woyera kapena ufa wonyezimira wofanana, wopanda magazini wamakina, wopanda fungo komanso wopanda tanthauzo

2. Kutentha kwa gel (℃): 60-90

3. Madzi okhutira （Wt%）: ≤5.0

4. Phulusa okhutira （Wt%）: ≤5.0

5.HP: 5.0-8.0

6. Choyimira: ≥80 Mesh

7. Kukhuthala （mPa.s, 2% yankho lamadzimadzi, 20 ± 0.2 ℃）: 100000-20000

Ntchito zazikulu zaluso

1. Solubility: modula H mu HEMC itha kusungunuka m'madzi ozizira ndi m'madzi otentha, pomwe mtundu wa L ungathe kusungunuka m'madzi ozizira, pomwe HEMC siisungunuke m'magawo ambiri amadzimadzi. Pamwamba pochotsedwa HEMC amamwazika m'madzi ozizira ndipo samachita zambiri. Komabe, imatha kusungunuka mwachangu posintha mtengo wake wa pH kukhala 8-10

2. Kukhazikika kwa PH: Mtengo wa pH pamitundu yosinthika ya 2-12 ndi yaying'ono, kupitilira kwa mawonekedwe awa kumachepa

3. HEMC ili ndi mawonekedwe akunenepa, kuyimitsidwa, kupezeka, kumamatira, emulsification, kupanga makanema komanso kusungira madzi, ndipo mphamvu yake yogwirizira madzi ndiyamphamvu kuposa methylcellulose. Kukhazikika kwa Viscosity, kukana kouma ndi kupezeka ndikwabwino kuposa hydroxyethyl cellulose

Ⅲ. Kagwiritsidwe ndi kusamala

HEMC imagwiritsidwa ntchito kwambiri paphala wamadzi okhala ndi madzi, zomangira ndi zomangamanga, inki yosindikiza, kubowola mafuta, ndi zina zambiri

Ⅳ. Phukusi ndi kusunga

Izi ndizomwe zili ndi pepala lolondola lachitetezo komanso chidziwitso chololeza chitetezo

2.Malonda awa amakhala ndi mapepala a 25kk komanso pulasitiki ya pulasitiki yolochedwa

3.Sitolo pamalo ouma, mverani chinyezi
