Urukuta rushyizweho nigice cyingenzi mubikorwa byo gushushanya.Ni uruvange rwa binders, kuzuza, pigment ninyongera zitanga ubuso burangije neza.Nyamara, mugihe cyo kubaka urukuta, ibibazo bimwe bishobora kugaragara, nko gutobora, kubira ifuro, nibindi. Gutanga ni ugukuraho ibintu birenze hejuru, mugihe ibisebe ari ugukora imifuka mito yumuyaga hejuru.Ibi bibazo byombi birashobora guhindura isura yanyuma yinkuta zisize irangi.Nyamara, hari igisubizo cyibi bibazo - koresha HPMC murukuta.
HPMC isobanura hydroxypropyl methylcellulose.Ni uruganda rukoreshwa cyane mubikorwa bitandukanye harimo nubwubatsi.HPMC ninyongera nziza kubitereko byurukuta kuko bitezimbere imikorere, guhuza hamwe nimbaraga zivanze.Imwe mu nyungu zingenzi zo gukoresha HPMC nubushobozi bwo kugabanya gutembera no guhuha.Dore ibice byukuntu HPMC ishobora gufasha gukuraho ibyo bibazo:
Gutanga
Gutanga ni ikibazo gikunze kugaragara mugihe ushyizeho urukuta.Ibi bibaho mugihe hari ibintu birenze hejuru bigomba gukurwaho.Ibi birashobora kuganisha ku buso butaringaniye no gukwirakwiza irangi ritaringanijwe mugihe ushushanya inkuta.HPMC irashobora kongerwaho kurukuta ruvanze kugirango wirinde kumurika.
HPMC ikora nka retarder muri putty putty, igabanya umuvuduko wigihe cyo kuvanga.Ibi bituma umwanya uhagije wo gutura hejuru nta bikoresho birenze.Hamwe na HPMC, imvange ya putty irashobora gukoreshwa murwego rumwe nta gusubiramo.
Mubyongeyeho, HPMC yongerera ubwiza rusange bwurukuta ruvanze.Ibi bivuze ko imvange ihagaze neza kandi ntibishoboka gutandukana cyangwa guhuriza hamwe.Nkigisubizo, urukuta rwuruvange rworoshye rworoshye gukorana kandi rukwirakwira byoroshye hejuru yubuso, bikagabanya gukenera.
bubbling
Guhuha ni ikindi kibazo gikunze kubaho mugihe cyo kubaka urukuta.Ibi bibaho iyo putty ikora umufuka muto wumuyaga hejuru yumye.Imifuka yumuyaga irashobora gutera ubuso butaringaniye kandi ikangiza isura yanyuma yurukuta iyo irangi.HPMC irashobora gufasha gukumira ibyo bituba.
HPMC ikora nka firime yahoze muri putty.Iyo putty yumye, ikora firime yoroheje hejuru yububiko.Iyi firime ikora nka bariyeri, irinda ubuhehere kwinjira cyane murukuta no gukora imifuka yumwuka.
Mubyongeyeho, HPMC yongera imbaraga zo guhuza urukuta rushyizwe hejuru.Ibi bivuze ko putty ifata neza hejuru, bikagabanya imiterere yimifuka yumwuka cyangwa icyuho kiri hagati yubuso nubuso.Hamwe na HPMC, uruvange rwurukuta ruvanze rukora ubumwe bukomeye hamwe nubuso, bikarinda ibisebe.
mu gusoza
Urukuta rushyizweho nigice cyingenzi mubikorwa byo gushushanya, kandi ni ngombwa kwemeza ko rufite iherezo ryiza.Kubaho guturika no guhuha birashobora kugira ingaruka kumpera yanyuma yurukuta rusize irangi.Ariko, gukoresha HPMC nk'inyongera kurukuta rushobora gufasha gukemura ibyo bibazo.HPMC ikora nka retarder yashyizweho, yongerera ubwiza bwuruvange kandi ikabuza ibintu birenze kurema hejuru.Muri icyo gihe, bifasha kurema ubumwe bukomeye hagati yurukuta rwubuso nubuso, bikarinda gushiraho imifuka yumwuka ninshi.Gukoresha HPMC mubikuta byerekana neza ko isura yanyuma yurukuta rusize irangi yoroshye, ndetse kandi itunganye.
