Hydroxypropyl methylcellulose (HPMC) ninyongeramusaruro inyuranye ikoreshwa cyane mubikorwa byubwubatsi, cyane cyane mububiko bwa plasta. Gypsum plaster, izwi kandi nka plaster ya Paris, ni ibikoresho byubaka bizwi cyane mu gutwikira inkuta no hejuru. HPMC igira uruhare runini mugutezimbere imikorere nimikorere ya gypsumu.
HPMC ni selile idafite ionic selile yabonetse muri polymer selulose naturel binyuze murukurikirane rwo guhindura imiti. Ihingurwa no kuvura selile hamwe na okiside ya propylene na methyl chloride. Ibicuruzwa bivamo ni ifu yera ibora mumazi kandi igakora igisubizo kibonerana.
Hano hari bimwe mubyingenzi byingenzi bya HPMC kuri plaster:
1. Kubika amazi:
Imwe mumikorere yibanze ya HPMC muri gypsum nubushobozi bwayo bwo gufata amazi. Ifasha kwirinda gutakaza vuba kwamazi mugihe cyo kumisha, bigatuma hashobora kugenzurwa cyane ndetse no gushiraho plaster. Ibi nibyingenzi kugirango ugere ku mbaraga zisabwa no guhora kwa plaster.
2. Kunoza imikorere:
HPMC itezimbere imikorere ya gypsumu itanga igihe cyiza cyo gufungura no kongera kunyerera. Ibi byoroshe gushira no gukwirakwiza stucco hejuru, bikavamo neza, ndetse bikarangira.
3. Gufatanya no guhuriza hamwe:
HPMC ifasha muguhuza plaque gypsum kuri substrate zitandukanye. Itezimbere gufatana hagati ya stucco nubuso bwinyuma, byemeza kuramba kandi kuramba. Mubyongeyeho, HPMC yongerera ubumwe bwa plaster ubwayo, bityo ikongerera imbaraga no kugabanya gucamo.
4. Ingaruka yibyibushye:
Mubisobanuro bya gypsumu, HPMC ikora nkibyimbye, bigira ingaruka kumyumvire yimvange ya gypsumu. Ingaruka yibyingenzi ningirakamaro kugirango ugere kumurongo wifuzwa hamwe nimiterere mugihe cyo gusaba. Ifasha kandi kwirinda stucco kugabanuka cyangwa kugwa hejuru yubutumburuke.
5. Shiraho igihe cyo kugenzura:
Kugenzura igihe cyo gushiraho gypsum plaster ningirakamaro mubikorwa byububiko. HPMC irashobora guhindura igihe cyo gushiraho kugirango itange ihinduka ryujuje ibisabwa byumushinga. Ibi ni ngombwa cyane cyane kubikorwa binini bishobora gusaba ibihe bitandukanye.
6. Ingaruka ku kwinezeza:
Kubaho kwa HPMC bigira ingaruka kumyuka ya gypsumu. Ipompa ikozwe neza hamwe na HPMC irashobora kongera imbaraga zo kurwanya amazi no kugabanya ubukana, bityo bikongerera igihe kirekire no kurwanya ibidukikije.
7. Guhuza nibindi byongeweho:
HPMC irahujwe nibindi bitandukanye byongeweho bikunze gukoreshwa muburyo bwa gypsumu. Ubu buryo bwinshi butuma ibivangwa bya plaster bihindurwa kugirango byuzuze imikorere yimikorere nibisabwa.
8. Ibidukikije:
HPMC muri rusange ifatwa nk'umutekano kandi utangiza ibidukikije. Ntabwo ari uburozi kandi ntabwo irekura ibintu byangiza mugihe cyangwa nyuma yo guhomeka. Ibi bihujwe no kwiyongera gushimangira ibikorwa byubaka birambye kandi byangiza ibidukikije.
Hydroxypropyl methylcellulose (HPMC) igira uruhare runini mugutezimbere imikorere ya gypsumu mubikorwa byubwubatsi. Kubika amazi, kunoza imikorere, gufatira hamwe, kubyibuha, gushiraho igihe, kugenzura ingaruka, guhuza nibindi byongeweho no gutekereza kubidukikije bituma iba inyongera yingirakamaro muburyo bwiza bwa gypsumu. Mugihe ibikorwa byubwubatsi bikomeje kugenda bitera imbere, HPMC ikomeje kuba ingenzi mu kuzamura imikorere no kuramba kwa gypsumu mu mishinga itandukanye yo kubaka no kubaka.
