Gypsum ni ibikoresho bisanzwe byubaka bikoreshwa mugushushanya imbere ninyuma.Irazwi cyane kuramba, ubwiza, no kurwanya umuriro.Nubwo, nubwo izo nyungu, plaster irashobora guteza imbere igihe, ishobora guhungabanya ubusugire bwayo kandi ikagira ingaruka kumiterere yayo.Kumena plasta birashobora kubaho kubwimpamvu zitandukanye, zirimo ibidukikije, kubaka bidakwiye, nibikoresho bidafite ireme.Mu myaka yashize, inyongeramusaruro ya hydroxypropyl methylcellulose (HPMC) yagaragaye nkigisubizo cyo gukumira ibimera.Iyi ngingo iragaragaza akamaro kongeramo HPMC mukurinda kumeneka plaster nuburyo ikora.
Niki HPMC yongeyeho kandi bakora gute?
HPMC inyongeramusaruro zikoreshwa mubisanzwe mubikorwa byubwubatsi nkibikoresho byo gutwikira hamwe nabahindura viscosity mubisabwa byinshi, harimo no guhomesha.Bikomoka kuri selile, birashobora gushonga mumazi akonje kandi ashyushye bityo birashobora gukoreshwa mubikorwa bitandukanye byubwubatsi.Iyo ivanze namazi, ifu ya HPMC ikora ibintu bisa na gel bishobora kwongerwaho imvange ya stucco cyangwa bigashyirwa nkigifuniko hejuru yinkuta zometseho.Imiterere ya gel isa na HPMC ituma ikwirakwira neza, ikarinda guhumeka gukabije kwubushuhe no kugabanya ibyago byo guturika.
Inyungu igaragara yinyongera ya HPMC nubushobozi bwo kugenzura igipimo cyamazi ya gypsumu, itanga ibihe byiza byo gushiraho.Izi nyongeramusaruro zitera inzitizi itinda kurekura amazi, bityo bikagabanya amahirwe yo gukama imburagihe no guturika nyuma.Byongeye kandi, HPMC irashobora gukwirakwiza umwuka mubi muvanga rya gypsumu, ifasha kunoza imikorere yayo kandi byoroshye kuyikoresha.
Irinde ibice bya plaster ukoresheje inyongera ya HPMC
