Cellulose ether HPMC muri sima ya sima na gypsumu ishingiye kuri slurry, cyane cyane igira uruhare mukubika amazi no kubyimba, birashobora kunoza neza kwifata no kurwanya sag.
Ubushyuhe bwo mu kirere, ubushyuhe n’umuvuduko w’umuyaga birashobora kugira ingaruka ku gipimo cy’amazi yo mu mazi ya sima na gypsumu.Mu bihe bitandukanye, ingaruka zo gufata amazi ya slurry zirashobora guhinduka mukongera cyangwa kugabanya umubare wa HPMC.Mu iyubakwa ry'ubushyuhe bwo hejuru mu cyi, kugirango tugere ku ngaruka zo kubungabunga amazi, ni ngombwa kongeramo ibicuruzwa bya HPMC ku bwinshi bihagije ukurikije formulaire.Bitabaye ibyo, hazabaho hydrated idahagije, kugabanya imbaraga, guturika, ingoma zidafite ishingiro no kumeneka biterwa no gukama vuba, nibindi bibazo byubuziranenge.Mugihe ubushyuhe bugabanutse, ingano ya HPMC irashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo gufata amazi zirashobora kugerwaho.
Hariho itandukaniro nimpamvu zituma amazi agumana ingaruka zingana kubicuruzwa byongeweho HPMC.Ibicuruzwa byiza bya HPMC birashobora gukemura neza ikibazo cyo gufata amazi munsi yubushyuhe bwinshi.Mu gihe cy'ubushyuhe bwinshi, cyane cyane ahantu hashyushye kandi humye no kubaka igicucu cyoroshye ku zuba, hakenewe HPMC yo mu rwego rwo hejuru kugira ngo amazi agabanuke neza.HPMC yo mu rwego rwo hejuru, imikorere ya hydroxypropyl hamwe na selile ya selile ya selile ikwirakwizwa, irashobora kunoza hydroxyl na ether kuri atome ya ogisijeni hamwe nubushobozi bwa hydrogène ihuza amazi, bigatuma amazi yubusa mumazi ahuriweho.Kandi ikwirakwizwa neza mumashanyarazi hanyuma igapfunyika ibice byose bikomeye, reaction ya hydrata hamwe nibikoresho bya sima ya organique, hamwe no gushiraho igice cya firime itose, amazi muribanze yarekuwe buhoro buhoro igihe kirekire, kugirango agenzure neza ihinduka ryamazi yatewe nubushyuhe bwo hejuru, kugirango amazi agumane.
Kugumana amazi yibicuruzwa bya HPMC bikunze kwibasirwa nimpamvu zikurikira:
1. Uburinganire bwa HPMC reaction Igisubizo kimwe cya HPMC, imikorerexy, hydroxypropoxy ikwirakwizwa, kugumana amazi menshi.
2 Ubushyuhe bwa HPMC gel Gel gel ishyushye ifite hejuru
ubushyuhe n'igipimo kinini cyo gufata amazi;bitabaye ibyo, ifite igipimo gito cyo gufata amazi.
3. Ubukonje bwa HPMC ： Iyo ubwiza bwa HPMC bwiyongereye, igipimo cyo gufata amazi nacyo kiriyongera.Iyo
viscosity igera ku rugero runaka, kwiyongera kw'igipimo cyo gufata amazi bikunda kuba byoroheje.
4. Ibirimo HPMC ： Uko HPMC yongeweho, niko igipimo cyo gufata amazi ari ninshi ningaruka zo gufata amazi.Mu ntera ya 0.25-0,6%, igipimo cyo kubungabunga amazi cyiyongereye vuba hamwe n’iyongera ry’amafaranga yiyongereye.Iyo amafaranga yiyongereye yiyongereye, inzira yo kongera igipimo cyo kubungabunga amazi yabaye gahoro.
