HydroxyPropyl MethylcellllALese (HPMC) ni umuhanga wa selile usanzwe ukoreshwa mu nganda zinyuranye, harimo na Gypsum mu nganda zubwubatsi. Iki kigo cyimisozi migwirane kigira uruhare runini mugutezimbere imikorere numutungo wa Plaster.
1. Kumenyekanisha HPMC:
HydroxyPropyl Methylcellse niko bakomoka kuri sinyoma ya selile karemano. Yakozwe no kuvura selile hamwe na propay okiside na methyl chloride. Igisubizo ni polymer-polymer ifite imitungo yihariye ishobora kubona porogaramu muburyo butandukanye.
2. Imikorere ya HPMC:
Amazi yonyine: HPMC irashonje byoroshye mumazi, ikora igisubizo kiboneye kandi idafite ibara.
Imiterere ya firime: Imiterere-ya firime ifasha gushiraho firime yo kurinda hejuru.
Ubushyuhe bwa Dolanal: HPMC ihura na pelation yo guhindukiramo ubushyuhe, bivuze ko ishobora gukora gel yubushyuhe bwo hejuru hanyuma agaruka igisubizo ku gukonja.
Viscosity: Ibyatsi byo gukemura HPMC birashobora guhindurwa bishingiye kurwego rwo gusimbuza nuburemere bwa molekile.
3. Gusaba HPMC muri Gypsum:
Ifungwa ry'amazi: HPMC ikora nk'umukozi ushinzwe kugumana amazi muri Gypsum, yirinda gutakaza amazi mugihe cyo gushiraho. Ibi byongerera imitekerereze kandi bitanga ubuzima bukuru bwo gusaba.
Imyitozo ngororamubiri: Imitungo yo gukora firime ya HPMC ifasha kunoza imitekerereze ya Stucco kubantu batandukanye, bashiraho ubumwe bukomeye.
Igenzura rihoraho: Mu kugenzura vicosity ya Gypsum imvange, HPMC ifasha gukomeza guhuza ibikorwa, kwemeza hejuru.
Kurwanya Crack: Gukoresha HPMC muri plaster bifasha kunoza guhinduka no kugabanya amahirwe yo gucamo ibicuruzwa byarangiye.
Gushiraho igihe: HPMC irashobora guhindura umwanya wa Gypsum kugirango ihindurwe kugirango ihuze ibisabwa.
4. Dosage no kuvanga:
Umubare wa HPMC ikoreshwa muri Gypsum biterwa nibintu bitandukanye nkibintu byifuzwa, imiterere ya Gypsum hamwe nibisabwa. Mubisanzwe, byongewe kumirometero yumye mugihe cyo kuvanga. Kuvanga inzira ni ngombwa kugirango utandukanye kandi ukore neza.
5.Igitugu n'umutekano:
HPMC irahuye nizindi nyandiko zitandukanye zikoreshwa muri plaque. Byongeye kandi, bifatwa nkimitekano yo gukoresha mubikoresho byubaka kandi byubahiriza ibipimo ngenderwaho bireba.
6. UMWANZURO:
HydroxyPropyl MethylcellllAlose (HPMC) ifite uruhare runini mugutezimbere imikorere ya Gypsum plaster. Umutungo wacyo wihariye ufasha kunoza ibikorwa, kuromera no mubwiza bwa plaster. Byakoreshejwe cyane mu nganda zubakwa, HPMC ikomeje kuba ikintu cyingenzi cya plaster nziza.
