Hydroxypropyl methylcellulose (HPMC) ni selile ya selile ikoreshwa cyane mu nganda zitandukanye, harimo na gypsumu mu bwubatsi.Uru ruganda rwimikorere myinshi rufite uruhare runini mugutezimbere imikorere nimiterere ya gypsumu.
1. Intangiriro kuri HPMC:
Hydroxypropyl methylcellulose ni intungamubiri ikomoka kuri selile isanzwe ya polymer.Ikorwa mukuvura selile hamwe na okiside ya propylene na methyl chloride.Igisubizo ni amazi-eruber polymer ifite imitungo idasanzwe ishobora kubona porogaramu mubikorwa bitandukanye byinganda.
2. Imikorere ya HPMC:
Amazi meza: HPMC irashobora gushonga byoroshye mumazi, ikora igisubizo kiboneye kandi kitagira ibara.
Ibikoresho byo gukora firime: Ibikoresho byo gukora firime bifasha gukora firime ikingira hejuru.
Ubushyuhe bwa Thermal: HPMC ihura nubushyuhe bwumuriro, bivuze ko ishobora gukora gele mubushyuhe bwinshi hanyuma igasubira mubisubizo imaze gukonja.
Viscosity: Ubukonje bwumuti wa HPMC burashobora guhinduka ukurikije urwego rwo gusimbuza nuburemere bwa molekile.
3. Gukoresha HPMC muri gypsumu:
Kubika amazi: HPMC ikora nk'igikoresho cyo gufata amazi muri gypsumu, ikarinda gutakaza amazi vuba mugihe cyo gushiraho.Ibi byongera imikorere kandi bitanga ubuzima burebure.
Kunoza neza Adhesion: Imiterere ya firime ya HPMC ifasha kunoza stucco ifatanye na substrate zitandukanye, bigatuma habaho ubumwe bukomeye.
Igenzura rihoraho: Mugucunga ubwiza bwimvange ya gypsumu, HPMC ifasha kugumya gukurikiza, kwemeza ubuso bumwe.
Kurwanya Crack: Gukoresha HPMC muri plaster bifasha kunoza imiterere kandi bigabanya amahirwe yo gucika mubicuruzwa byarangiye.
Gushiraho Igihe: HPMC irashobora guhindura igihe cyo gushiraho gypsumu kuburyo ishobora guhinduka kugirango ihuze ibisabwa byihariye.
4. Ingano no kuvanga:
Ingano ya HPMC ikoreshwa muri gypsumu biterwa nibintu bitandukanye nkumutungo wifuzwa, gukora gypsumu nibisabwa.Mubisanzwe, byongewe kumuvange wumye mugihe cyo kuvanga.Uburyo bwo kuvanga nibyingenzi kugirango habeho gutandukana kimwe no gukora neza.
5.Kudahuza n'umutekano:
HPMC irahujwe nibindi bintu bitandukanye byongeweho bikoreshwa muguhimba plaster.Byongeye kandi, bifatwa nkumutekano gukoreshwa mubikoresho byubwubatsi kandi byubahiriza ibipimo ngenderwaho bijyanye.
6. Umwanzuro:
Hydroxypropyl methylcellulose (HPMC) igira uruhare runini mugutezimbere imikorere ya gypsumu.Imiterere yihariye ifasha kunoza imikorere, gufatana hamwe nubwiza rusange bwa plasta.Inyongeramusaruro ikoreshwa cyane mubikorwa byubwubatsi, HPMC ikomeje kuba ikintu cyingenzi cyibikoresho byo mu rwego rwo hejuru.
