Magwiridwe antchito a HPMC
Hydroxypropyl methyl cellulose (HPMC) ndi mtundu wa ether ya cellulose yosakhala ionic, yomwe imapangidwa ndi zinthu zachilengedwe za polima ngati zopangira ndipo imakonzedwa ndi njira zingapo zamankhwala. Lero tiphunzira za momwe HPMC imagwirira ntchito.
● Kusungunuka kwa madzi: kumatha kusungunuka m'madzi molingana ndi kuchuluka kwake, kuchuluka kwake kwakukulu kumadalira kukhuthala kwake, ndipo kusungunukako sikukhudzidwa ndi PH.l Kusungunuka kwachilengedwe: HPMC ikhoza kusungunuka m'madzi ena osungunuka kapena m'madzi osungunuka monga dichloroethane, yankho la ethanol, ndi zina zotero.
● Makhalidwe a gel yotenthetsera: Gel yosinthika idzawonekera pamene yankho lawo lamadzi litenthedwa kutentha kwinakwake, ndi magwiridwe antchito owongolera mwachangu.
● Palibe mphamvu ya ionic: HPMC ndi ether ya cellulose yosakhala ionic ndipo sidzagwirizana ndi ayoni achitsulo kapena zamoyo kuti ipange ma precipitates osasungunuka.
● Kukhuthala: Njira yake yothetsera madzi imakhala ndi kukhuthala, ndipo kukhuthala kwake kumakhudzana ndi kukhuthala kwake, kuchuluka kwake, ndi dongosolo lake.
● Kusunga madzi: HPMC kapena yankho lake limatha kuyamwa ndi kusunga madzi.
● Kupanga filimu: HPMC ikhoza kupangidwa kukhala filimu yosalala, yolimba, komanso yotanuka, ndipo imakhala ndi kukana mafuta ndi okosijeni bwino.
● Kukana kwa ma enzyme: Yankho la HPMC lili ndi kukana kwabwino kwa ma enzyme komanso kukhazikika kwabwino kwa kukhuthala.
● Kukhazikika kwa PH: HPMC ndi yokhazikika pang'ono ku asidi ndi alkali, ndipo pH simakhudzidwa pakati pa 3-11. (10) Ntchito ya pamwamba: HPMC imapereka ntchito ya pamwamba mu yankho kuti ikwaniritse emulsification yofunikira komanso zotsatira zoteteza za colloid.
● Kapangidwe kake koletsa kugwa: HPMC imawonjezera kapangidwe ka thixotropic ku ufa wa putty, mortar, tile glue, ndi zinthu zina, ndipo ili ndi luso labwino kwambiri loletsa kugwa.
● Kufalikira: HPMC ikhoza kuchepetsa kupsinjika kwa pakati pa magawo ndikupanga gawo lofalikira kuti lifalikire mofanana m'madontho a kukula koyenera.
● Kumatira: Kungagwiritsidwe ntchito ngati chomangira cha kuchuluka kwa utoto: pepala la 370-380g/l³, ndipo kungagwiritsidwenso ntchito mu zokutira ndi zomatira.
● Mafuta: Angagwiritsidwe ntchito mu rabara, asbestos, simenti, ndi zinthu zadothi kuti achepetse kukangana ndikuwonjezera kulowetsedwa kwa dothi la konkire.
● Kuyimitsa: Kungalepheretse tinthu tokhazikika kuti tisagwere mvula ndikuletsa kupangika kwa mvula.
● Kusakaniza: Chifukwa chakuti kumachepetsa kupsinjika kwa pamwamba ndi pakati pa nkhope, kumatha kukhazikika mu emulsion.
● Colloid yoteteza: Chotchinga chimapangidwa pamwamba pa madontho omwazikana kuti madonthowo asagwirizane ndi kusonkhana kuti apeze chitetezo chokhazikika.
