Hydroxypropylmethylcellulose (HPMC) ni ikintu cyingenzi kandi gihindagurika gikoreshwa mu nganda nyinshi harimo na plaster.HPMC ni selile ya selile ikomoka kuri selile kandi ni polymer idasanzwe, amazi ashonga.Bikunze gukoreshwa nkibibyimbye, stabilisateur na emulisiferi kumasoko atose kandi yumye.Mu nganda za gypsumu, HPMC ikoreshwa nkikwirakwiza kandi ikabyimbye.Iyi ngingo irambuye ibyiza byo gukoresha HPMC mu musaruro wa gypsumu.
Gypsum ni amabuye y'agaciro asanzwe akoreshwa mu nganda zubaka mu gukora sima na gypsumu.Kugirango ukore ibicuruzwa bya gypsumu, gypsumu igomba kubanza gutunganyirizwa muburyo bwifu.Inzira yo gukora ifu ya gypsumu ikubiyemo kumenagura no gusya imyunyu ngugu, hanyuma ukayishyushya ubushyuhe bwinshi kugirango ukureho amazi arenze.Ifu yumye ivamo noneho ivangwa namazi kugirango ikore paste cyangwa slurry.
Imwe mu miterere yingenzi ya HPMC munganda za gypsumu nubushobozi bwayo bwo gukwirakwiza.Mu bicuruzwa bya gypsumu, HPMC ikora nk'itatanya, igabanya uduce duto duto kandi ikemeza ko igabanywa rimwe muri rusange.Ibi bivamo ibisubizo byoroshye, bihamye byoroshye byoroshye gukorana.
Usibye kuba itatanye, HPMC nayo irabyimbye.Ifasha kongera ububobere bwa gypsum slurry, byoroshye gucunga no gushyira mubikorwa.Ibi ni ingenzi cyane kubicuruzwa bisaba guhorana umubyimba mwinshi, nkibihuriweho cyangwa plaster.
Iyindi nyungu ikomeye ya HPMC mu nganda za gypsumu ni imikorere yayo myiza.Ongeraho HPMC kuri gypsum slurries ituma ibicuruzwa bikwirakwizwa byoroshye kandi bigakora igihe kirekire.Ibi bivuze ko abashoramari nabantu ku giti cyabo bafite igihe kinini cyo gukora kubicuruzwa mbere yuko bishyiraho.
HPMC nayo itezimbere ubuziranenge nigihe kirekire cyibicuruzwa byanyuma.Mugukora nk'ikwirakwiza, HPMC iremeza ko gypsumu igabanijwe neza mubicuruzwa.Ibi bituma ibicuruzwa biramba, bigahoraho kandi ntibikunze gucika no kumeneka.
HPMC ni ibidukikije byangiza ibidukikije.Ntabwo ari uburozi, ibinyabuzima kandi ntibitera umwanda.Ibi bituma ihitamo neza ku nganda zita ku ngaruka z’ibidukikije ku bicuruzwa byabo.
HPMC nikintu cyingenzi mumuryango wa gypsumu ufite inyungu nyinshi.Ubushobozi bwayo bwo gukwirakwiza, kubyimba, kunoza imikorere no kurangiza ibicuruzwa byarangije kuba igice cyinganda.Ibidukikije byangiza ibidukikije nabyo ni inyungu igaragara kwisi aho inganda nyinshi zishaka kugabanya ingaruka z’ibidukikije.
mu gusoza
Hydroxypropylmethylcellulose (HPMC) nikintu cyingenzi murwego rwa plasta.Ubushobozi bwayo bwo gukwirakwiza, kubyimba, kunoza imikorere no kurangiza ibicuruzwa byarangije kuba igice cyingenzi cyinganda.Byongeye kandi, ibidukikije byangiza ibidukikije ninyungu zikomeye kwisi aho inganda nyinshi zifuza kugabanya ingaruka z’ibidukikije.Muri rusange, HPMC ni amahitamo meza ku nganda iyo ari yo yose ishaka kuzamura ireme ry'ibicuruzwa byabo ndetse no kumenya ingaruka z’ibidukikije.
