Pali mafakitale monosodium glutamate, carboxymethyl cellulose, hydroxypropyl methyl cellulose, ndihydroxyethyl cellulose, omwe amagwiritsidwa ntchito kwambiri.Pakati pa mitundu itatu ya cellulose, yovuta kwambiri kusiyanitsa ndi hydroxypropyl methylcellulose ndi hydroxyethyl cellulose.Tiyeni tisiyanitse mitundu iwiriyi ya cellulose ndi ntchito ndi ntchito zake.
Monga si ionic surfactant, hydroxyethyl cellulose ili ndi zinthu zotsatirazi kuphatikiza kuyimitsa, kukhuthala, kubalalitsa, kuyandama, kulumikiza, kupanga mafilimu, kusunga madzi komanso kupereka ma colloid oteteza:
1. HEC palokha si ionic ndipo imatha kukhala limodzi ndi ma polima ena osungunuka m'madzi, ma surfactants, ndi mchere.Ndi colloidal thickener yabwino kwambiri yomwe ili ndi mayankho a electrolyte apamwamba kwambiri.
2. Poyerekeza ndi methyl cellulose yodziwika bwino ndi hydroxypropyl methyl cellulose, mphamvu yobalalika ya HEC ndiyoipa kwambiri, koma colloid yoteteza imakhala ndi mphamvu zolimba kwambiri.
3. Mphamvu yosungira madzi imakhala yowirikiza kawiri kuposa ya methyl cellulose, ndipo imakhala ndi malamulo oyendetsera bwino.
4. HEC imasungunuka m'madzi otentha kapena ozizira, ndipo sichitha kutentha kwambiri kapena kutentha, choncho imakhala ndi mitundu yambiri ya solubility ndi viscosity, komanso gelation yopanda kutentha.
HEC ntchito: zambiri ntchito monga thickening wothandizila, zoteteza wothandizila, zomatira, stabilizer ndi kukonzekera emulsion, odzola, mafuta odzola, odzola, maso kuchotsa.
Chiyambi cha ntchito ya Hydroxypropyl methylcellulose (HPMC):
1. Kupaka mafakitale: monga thickener, dispersant ndi stabilizer mu makampani ❖ kuyanika, izo zimagwirizana bwino mu madzi kapena organic solvents.monga chochotsera utoto.
2. Kupanga Ceramic: kumagwiritsidwa ntchito kwambiri ngati chomangira popanga zinthu za ceramic.
3. Zina: Izi zimagwiritsidwanso ntchito kwambiri pazikopa, makampani opanga mapepala, kusunga zipatso ndi masamba ndi mafakitale a nsalu, ndi zina zotero.
4. Kusindikiza kwa inki: monga thickener, dispersant ndi stabilizer mu makampani a inki, zimakhala zogwirizana bwino m'madzi kapena organic solvents.
5. Pulasitiki: imagwiritsidwa ntchito ngati chotulutsa nkhungu, chofewa, mafuta odzola, etc.
6. Polyvinyl chloride: Amagwiritsidwa ntchito ngati dispersant popanga polyvinyl chloride, ndipo ndiye wothandizira wamkulu pokonza PVC poyimitsa polymerization.
7. Makampani omangamanga: Monga chosungira madzi komanso chochepetsera matope a mchenga wa simenti, zimapangitsa kuti mchengawo ukhale wopopera.Amagwiritsidwa ntchito ngati chomangira popaka pulasitala, gypsum, putty powder kapena zinthu zina zomangira kuti azitha kufalikira ndikutalikitsa nthawi yogwira ntchito.Amagwiritsidwa ntchito ngati phala la matailosi a ceramic, marble, zokongoletsera zapulasitiki, monga chowonjezera cha phala, komanso amatha kuchepetsa kuchuluka kwa simenti.Kusungidwa kwa madzi kwa HPMC kumatha kuletsa slurry kuti isaphwanyike chifukwa chowuma mwachangu mukatha kugwiritsa ntchito, ndikuwonjezera mphamvu mukaumitsa.
