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 irerekana 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 bimeze nka gel bishobora kwongerwaho imvange ya stucco cyangwa bigashyirwa nkigifuniko hejuru yinkuta zometseho. Imiterere ya gel isa na HPMC ituma ikwirakwira neza, ikarinda guhumeka gukabije kwamazi 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
Kugabanuka
Imwe mumpamvu nyamukuru zitera kumena plaster ni ukumisha kugabanuka kwubuso. Ibi bibaho iyo stucco yumye ikagabanuka, bigatera impagarara zitera gucika. Inyongeramusaruro za HPMC zirashobora gufasha kugabanya kugabanuka kwumye mugabanya umuvuduko amazi ava mumavange ya gypsumu, bigatuma habaho no gukwirakwiza amazi.

Kuvanga bidakwiye
Mubihe byinshi, plaque ivanze nabi bizavamo ingingo zintege nke zishobora gucika byoroshye. Gukoresha inyongera ya HPMC mvange ya gypsum birashobora gufasha kunoza imitungo yubwubatsi no gukora inzira yubwubatsi. Izi nyongeramusaruro zikwirakwiza amazi neza muri plaster, zitanga imbaraga zihoraho no kugabanya ibyago byo guturika.
ihindagurika ry'ubushyuhe
Ubushyuhe bukabije burashobora gutuma stucco yaguka kandi ikagabanuka, bigatera impagarara zishobora gukurura. Gukoresha inyongeramusaruro za HPMC bigabanya umuvuduko wo guhumeka amazi, bityo bikadindiza inzira yo gukira no kugabanya ibyago byo kwaguka vuba. Iyo plaster yumye neza, igabanya ubushobozi bwahantu hashobora gukabya, bigatera impagarara zishobora gukurura.
Igihe cyo gukiza kidahagije
Ahari ikintu cyingenzi mugucamo plaster nigihe kidahagije cyo gukiza. HPMC inyongera itinda kurekura amazi ava muri gypsumu, bityo ikongerera igihe cyo gushiraho. Igihe kinini cyo gukiza gitezimbere ubudahangarwa bwa stucco kandi bigabanya isura yibibara bidakomeye bishobora gucika. Byongeye kandi, inyongeramusaruro za HPMC zifasha gukora inzitizi yikirere gikabije gishobora gutera ibice ahantu hagaragara.
mu gusoza
Gucika muri stucco birasanzwe mubikorwa byubwubatsi kandi birashobora kuganisha ku gusana bihenze kandi bitagira inenge. Mugihe hariho ibintu byinshi bishobora gutera ibice muri plaster, gukoresha inyongera ya HPMC nigisubizo cyiza cyo gukumira ibice. Imikorere yinyongera ya HPMC nugukora inzitizi irinda guhumeka gukabije kwamazi kandi bikagabanya kugabanuka kwumye no kwaguka kwinshi. Izi nyongeramusaruro nazo zitezimbere imikorere, bikavamo imbaraga zihamye hamwe nubwiza bwa plaster. Mugushyiramo inyongeramusaruro ya HPMC kumvange ya plaster, abubatsi barashobora kwemeza neza kuramba, kugaragara neza.
