1. Katundu wa hydroxyethyl cellulose
Izi ndi zoyera kapena zowala zachikasu zopanda fungo komanso zosavuta kuyenda ufa, 40 mauna sieve mlingo ≥99%;kutentha kofewa: 135-140 ° C;kachulukidwe kowoneka bwino: 0.35-0.61g/ml;kutentha kwa kuwonongeka: 205-210 ° C;liwiro loyaka Pang'onopang'ono;kutentha kwapakati: 23 ° C;6% pa 50% rh, 29% pa 84% rh.
Imasungunuka m'madzi ozizira ndi madzi otentha, ndipo nthawi zambiri imasungunuka m'madzi ambiri osungunulira organic.Kukhuthala kumasintha pang'ono mumtundu wa PH mtengo 2-12, koma kukhuthala kumachepera kuposa izi.
2. Zinthu zofunika
Monga surfactant yopanda ionic,hydroxyethyl celluloseali ndi zinthu zotsatirazi kuwonjezera kukhuthala, kuyimitsa, kumanga, kuyandama, kupanga filimu, kubalalitsa, kusunga madzi ndi kupereka colloid zoteteza:
1. HEC imasungunuka m'madzi otentha kapena madzi ozizira, ndipo sichimawotcha kutentha kwambiri kapena kutentha, zomwe zimapangitsa kuti zikhale ndi zosungunuka zambiri, maonekedwe a viscosity ndi gelation yopanda kutentha.
2. Siionic ndipo imatha kukhala limodzi ndi ma polima ena osungunuka m'madzi, ma surfactants, ndi mchere.Ndiwothira bwino kwambiri wa colloidal pamayankho a electrolyte apamwamba kwambiri.
3. Mphamvu yosungira madzi imakhala yowirikiza kawiri kuposa ya methyl cellulose, ndipo imakhala ndi malamulo oyendetsera bwino.
4. Poyerekeza ndi methyl cellulose yodziwika bwino ndi hydroxypropyl methyl cellulose, HEC ili ndi mphamvu yowononga kwambiri, koma mphamvu yoteteza kwambiri ya colloid.
3. Kugwiritsa ntchito hydroxyethyl cellulose
Nthawi zambiri amagwiritsidwa ntchito monga thickeners, zoteteza, zomatira, stabilizers ndi zina pokonzekera emulsions, zakudya, mafuta odzola, odzola maso, suppositories ndi mapiritsi, komanso ntchito monga hydrophilic gels, chigoba zipangizo, Angagwiritsidwe ntchito pokonzekera masanjidwewo - mtundu wokhazikika-kumasulidwa kukonzekera, ndipo angagwiritsidwenso ntchito monga stabilizer mu chakudya.
