Kodi Kusiyana kwa HPMC ndi HEC ndi Chiyani?

HPMC ndi Hydroxypropyl methyl cellulose ether ndipo HEC ndi hydroxyethyl cellulose ether.

Chiyambi cha Hydroxypropyl methyl cellulose (HPMC):

1, makampani omanga: monga madzi ndi silt slurry posungirako wothandizira, retarder kupanga slurry kupopera. Popaka pulasitala, gypsum, putty powder kapena zinthu zina zomangira monga zomatira, sinthani daub ndikutalikitsa nthawi yogwira ntchito. Amagwiritsidwa ntchito popaka matailosi a ceramic, marble, kukongoletsa kwa pulasitiki, phala kulimbikitsa wothandizira, komabe amatha kuchepetsa mlingo wa simenti.Mtengo wa HPMCmadzi posungira ntchito kumapangitsa slurry pambuyo ntchito sadzakhala chifukwa youma mofulumira kwambiri ndi kusweka, kuonjezera mphamvu pambuyo kuumitsa.

2, kupanga ceramic: imagwiritsidwa ntchito kwambiri ngati zomatira pakupanga zinthu za ceramic.

3, makampani ❖ kuyanika: mu ❖ kuyanika makampani monga thickener, dispersant ndi stabilizer, m'madzi kapena zosungunulira organic ndi solubility wabwino. Monga chochotsera utoto.

4, inki kusindikiza: mu makampani inki monga thickener, dispersant ndi stabilizer, m'madzi kapena zosungunulira organic ndi solubility wabwino.

5, pulasitiki: kupanga chotulutsa, chofewetsa, mafuta, etc.

6, PVC: kupanga PVC monga dispersant, kuyimitsidwa polymerization kukonzekera PVC othandizira chachikulu. 7, Ena: mankhwalawa amagwiritsidwanso ntchito kwambiri mu zikopa, makampani opanga mapepala, kusunga zipatso ndi masamba ndi mafakitale a nsalu.

Chiyambi cha Hydroxyethyl cellulose (HEC):

HEC Hydroxyethyl cellulose, monga mtundu wa nonionic surfactant, kuwonjezera thickening, kuyandama, kuyandama, ndi filimu kupanga, kubalalitsidwa, madzi, ndi kupereka colloid zoteteza, alinso katundu zotsatirazi:

1, HEC sungunuka m'madzi otentha kapena madzi ozizira, otentha kapena otentha osati mpweya, kupanga izo ali osiyanasiyana solubility ndi mamasukidwe akayendedwe katundu, ndi sanali matenthedwe gel osakaniza;

2, non-ionic ake akhoza kukhala limodzi ndi osiyanasiyana ma polima ena osungunuka m'madzi, ma surfactants, mchere, ndicolloidal thickener wabwino kwambiri wokhala ndi njira zambiri za electrolyte;

3, mphamvu yosungira madzi ndiyokwera kawiri kuposa methyl cellulose, yokhala ndi malamulo oyenda bwino, 4, kuthekera kobalalika kwa HEC poyerekeza ndi kuzindikirika kwa methyl cellulose ndi hydroxypropyl methyl cellulose dispersion kuthekera koyipa kwambiri, koma kuthekera koteteza colloidal ndikwamphamvu kwambiri.

Kagwiritsidwe: Nthawi zambiri amagwiritsidwa ntchito ngati thickening wothandizira, woteteza, zomatira, stabilizer ndi zowonjezera pokonzekera emulsion, odzola, mafuta odzola, odzola, oyeretsa maso, suppository ndi piritsi, amagwiritsidwanso ntchito ngati gel hydrophilic, mafupa a mafupa, kukonzekera mtundu wa mafupa omasulidwa. kukonzekera, kungagwiritsidwenso ntchito ngati stabilizer mu chakudya.
