MHEC LH 620M

EipponCell MHEC LH 620M methyl hydroxyethyl selulose ikoreshwa muri gypsum slurry kugirango itange ingaruka zigaragara.Ku bushyuhe bwicyumba, uko viscosity na dosiye ya selulose ether yiyongera, ingaruka zayo ziyongera cyane.Nyamara, uko ubushyuhe buzamuka, ubwiza bwa selile ya selile bugabanuka, bikaviramo intege nke zingaruka zayo.Ibi biganisha ku kugabanuka k'umusemburo wumusaruro, ubukonje bwa plastike, hamwe na pseudoplastique yimvange ya gypsumu, amaherezo bikaviramo gukora nabi.

Cellulose ether yongerera amazi gypsumu.Nyamara, uko ubushyuhe bwiyongera, kugumana amazi ya gypsumu yahinduwe bigabanuka cyane ndetse bikanatakaza burundu ingaruka zo gufata neza amazi kuri 60 ° C.Igipimo cyo gufata amazi ya gypsum slurry cyatejwe imbere cyane na selile ya selile, kandi igipimo cyo gufata amazi gahoro gahoro kigera aho cyuzura hamwe no kwiyongera kwibintu bya HPMC byahinduwe na gypsum slurry hamwe nubwiza butandukanye.Mubisanzwe, gufata amazi ya gypsumu bigereranywa nubwiza bwa selile ya ether, ariko ntigira ingaruka nke mubwiza bwinshi.

Imihindagurikire yo gufata amazi ya selile ya selile hamwe nubushyuhe bifitanye isano rya bugufi na microscopique morphologie ya selile ya selile mugice cyamazi.Kwibanda cyane, selile ya selile ikunda kwegeranya no gushinga amashyirahamwe manini ya colloidal, bikabuza neza imiyoboro yo gutanga amazi yimvange ya gypsumu kugirango igumane amazi neza.Nyamara, uko ubushyuhe buzamuka, imiterere yumuriro wa selulose ether itera amashyirahamwe manini ya colloidal yabanje gushingwa kongera gutatana, bigatuma kugabanuka kwamazi kugabanuka.
