Gypsum ihuriweho, izwi kandi nk'icyuma cyumye cyangwa icyuma gihuriweho gusa, ni ibikoresho byubwubatsi bikoreshwa mukubaka no gusana ibyuma byumye.Igizwe ahanini nifu ya gypsum, minerval yoroshye ya sulfate ivanze namazi kugirango ikore paste.Iyi paste noneho ikoreshwa kumurongo, inguni, no gutandukanya icyuma cyumye kugirango habeho ubuso bworoshye, butagira ikizinga.
Hydroxypropyl methylcellulose (HPMC) ni selile ya selile ikunze kongerwaho ibikoresho byahurijwe hamwe kubwimpamvu zitandukanye.HPMC ikomoka kuri selile, polymer karemano iboneka murukuta rw'utugingo ngengabuzima.Hano haribintu bimwe byingenzi byo gukoresha HPMC mububiko bwa plaster:
Kubika Amazi: HPMC izwiho uburyo bwiza bwo gufata amazi.Iyo wongeyeho plaque ihuriweho, ifasha kurinda imvange gukama vuba.Igihe kinini cyakazi cyoroshe gusaba no kurangiza ibikoresho bihuriweho.
Kunoza imikorere: Kwiyongera kwa HPMC byongera uburyo bwo guhuza ibice.Itanga ubudahwema bworoshye, byoroshye kuyikoresha no kuyikoresha hejuru yumye.Ibi nibyingenzi cyane kugirango ugere kubisubizo-byumwuga.
Adhesion: HPMC ifasha ifatanyirizo guhuza kwumisha hejuru yumye.Ifasha uruganda gukomera neza hamwe ningingo, byemeza ubumwe bukomeye kandi burambye igihe ibintu byumye.
Mugabanye kugabanuka: Ibikoresho bya gypsumu bikunda kugabanuka uko byumye.Kwiyongera kwa HPMC bifasha kugabanya kugabanuka no kugabanya amahirwe yo gucika kugaragara hejuru yuzuye.Ibi nibyingenzi kugirango tubone ibisubizo byuzuye kandi birebire.
Umukozi winjira mu kirere: HPMC nayo ikora nk'umukozi winjiza ikirere.Ibi bivuze ko bifasha kwinjiza microscopique yumuyaga mwinshi mubikoresho, bikanoza imikorere muri rusange kandi biramba.
Igenzura rihoraho: HPMC itanga igenzura ryinshi kubijyanye no guhuriza hamwe.Ibi byorohereza kugera kubintu byifuzwa hamwe nubunini mugihe cyo gusaba.
Ni ngombwa kumenya ko uburyo bwihariye bwibikoresho bya gypsumu bishobora gutandukana kubakora nuwabikoze, kandi amanota atandukanye ya HPMC arashobora gukoreshwa bitewe nibintu byifuzwa byibicuruzwa byanyuma.Byongeye kandi, ibindi byongeweho nkibibyimbye, binders na retarders birashobora gushirwa mubikorwa kugirango turusheho kunoza imikorere.
Hydroxypropyl methylcellulose (HPMC) selulose ether igira uruhare runini mugutezimbere imikorere, gufatira hamwe no muri rusange imikorere ya gypsum ihuriweho ikoreshwa mukubaka no gusana.Imiterere yayo itandukanye ifasha kugera kurangiza neza kandi biramba hejuru yumye.
