Kugwiritsa Ntchito Ntchito kwa HPMC
Hydroxypropyl methyl cellulose (HPMC) ndi mtundu wa ether wopanda ionic cellulose, wopangidwa ndi zinthu zachilengedwe za polima monga zida zopangira ndikuyengedwa ndi njira zingapo zama mankhwala. Lero tiphunzira za magwiridwe antchito a HPMC.
● Kusungunuka kwa madzi: kumatha kusungunuka m'madzi mumtundu uliwonse, chiwerengero chapamwamba kwambiri chimadalira kukhuthala, ndipo kusungunuka sikukhudzidwa ndi PH.l Organic solubility: HPMC ikhoza kusungunuka muzitsulo zina za organic kapena organic solvent aqueous solutions monga dichloroethane, ethanol solution, etc.
● Mawonekedwe a gel otenthetsera: Geli yosinthika imawonekera pamene madzi ake amadzimadzi atenthedwa ndi kutentha kwina, ndikuwongolera kofulumira.
● Palibe mtengo wa ionic: HPMC ndi ether yopanda ionic cellulose ndipo sidzavuta ndi ayoni achitsulo kapena organic kupanga madzi osasungunuka.
● Kukhuthala: Njira yake yamadzimadzi yamadzimadzi imakhala yokhuthala, ndipo kukhuthala kwake kumagwirizana ndi kukhuthala kwake, kukhazikika kwake, ndi dongosolo lake.
● Kusunga madzi: HPMC kapena yankho lake limatha kuyamwa ndi kusunga madzi.
● Mapangidwe a filimu: HPMC ikhoza kupangidwa kukhala filimu yosalala, yolimba, komanso yotanuka, ndipo imakhala ndi mafuta abwino kwambiri komanso osakanizidwa ndi okosijeni.
● Kukana kwa enzyme: Yankho la HPMC lili ndi kukana kwa ma enzyme komanso kukhazikika kwabwino kwa viscosity.
● Kukhazikika kwa PH: HPMC imakhala yokhazikika ku asidi ndi alkali, ndipo pH sichimakhudzidwa mumtundu wa 3-11. (10) Zochita zapamtunda: HPMC imapereka zochitika zapamtunda mu yankho kuti mukwaniritse zofunikira za emulsification ndi chitetezo cha colloid.
● Anti-sagging katundu: HPMC akuwonjezera katundu thixotropic dongosolo putty ufa, matope, matailosi guluu, ndi zinthu zina, ndipo ali kwambiri anti-sagging luso.
● Dispersibility: HPMC ikhoza kuchepetsa kusagwirizana pakati pa magawo ndi kupanga gawo lobalalika mofanana lomwazikana kukhala madontho a kukula koyenera.
● Kumamatira: Itha kugwiritsidwa ntchito ngati chomangira pakuchulukira kwa pigment: 370-380g/l³ pepala, ndipo itha kugwiritsidwanso ntchito popaka ndi zomatira.
● Mafuta Othira: Angagwiritsidwe ntchito popanga mphira, asibesitosi, simenti, ndi zinthu zadothi kuti achepetse kugundana komanso kupangitsa kuti matope a konkire asadutse.
● Kuyimitsidwa: Kungathe kulepheretsa tinthu tokhazikika kugwa mvula ndi kulepheretsa mapangidwe a mvula.
● Emulsification: Chifukwa imatha kuchepetsa kugwedezeka kwa pamwamba ndi nkhope, imatha kukhazikika emulsion.
● Chitetezo cha colloid: Chophimba chotetezera chimapangidwa pamwamba pa madontho obalalika kuti ateteze madontho kuti asagwirizane ndi kugwirizanitsa kuti akwaniritse chitetezo chokhazikika.
