Hydroxypropyl methylcellulose ether HPMC isa ite?

Muri putty, sima ya sima na gypsumu ishingiye kuri slurry,HPMChydroxypropyl methylcellulose ether ahanini igira uruhare mukubungabunga amazi no kubyimba, kandi irashobora kunoza neza kwifata no kurwanya sag. Ibintu nkubushyuhe bwikirere, ubushyuhe numuvuduko wumuvuduko wumuyaga bizagira ingaruka kumuvuduko wamazi wamazi muri putty, sima ya sima nibicuruzwa bishingiye kuri gypsumu. Kubwibyo, mubihe bitandukanye, hariho itandukaniro mubikorwa byo gufata amazi yibicuruzwa hamwe na HPMC yongeyeho. Mu bwubatsi bwihariye, ingaruka zo gufata amazi ya slurry zirashobora guhinduka mukwongera cyangwa kugabanya umubare wa HPMC wongeyeho.

Kugumana amazi ya methyl selulose ether mubihe byubushyuhe bwo hejuru nikimenyetso cyingenzi cyo gutandukanya ubwiza bwa methyl selulose ether. Ibicuruzwa byiza bya HPMC birashobora gukemura neza ikibazo cyo gufata amazi munsi yubushyuhe bwinshi. Mu bihe by'ubushyuhe bwinshi, cyane cyane ahantu hashyushye kandi humye no kubaka ibice bito ku ruhande rw'izuba, HPMC yo mu rwego rwo hejuru irasabwa kunoza uburyo bwo gufata neza amazi. HPMC yo mu rwego rwo hejuru irashobora guhindura amazi yubusa muri minisiteri mumazi aboshye, bityo bikagenzura neza ihinduka ryamazi yatewe nikirere cyinshi kandi ikagumana amazi menshi.

Methyl selulose yo mu rwego rwohejuru irashobora gukwirakwizwa neza kandi neza mugisima cya sima hamwe nibicuruzwa bishingiye kuri gypsumu, hanyuma ugapfunyika ibice byose bikomeye, hanyuma ugakora firime itose, hanyuma amazi akazarekurwa buhoro buhoro mugihe kirekire. Hydrasiyo reaction ibaho, bityo igahuza imbaraga zububasha nimbaraga zo kwikuramo ibintu. Kubwibyo, mubwubatsi bwubushyuhe bwo hejuru bwubushyuhe, kugirango tugere ku ngaruka zo gufata amazi, birakenewe kongeramo ibicuruzwa byiza bya HPMC muburyo buhagije ukurikije formulaire. Niba ikoreshwa rya HPMC rikoreshwa, hydrated idahagije, imbaraga zagabanutse, guturika, nubusa bizabaho kubera gukama cyane. Ibibazo byiza nkingoma no kumena nabyo byongera ingorane zo kubaka kubakozi. Mugihe ubushyuhe bugabanutse, ingano ya HPMC yongeweho irashobora kugabanuka buhoro buhoro, kandi ingaruka zimwe zo gufata amazi zirashobora kugerwaho.

Inzira yo kubyitwaramo igenzura neza umusaruro waHPMC, no kuyisimbuza byuzuye kandi uburinganire bwayo nibyiza cyane. Igisubizo cyamazi cyacyo kirasobanutse kandi kibonerana, hamwe na fibre nkeya. Guhuza ifu ya reberi, sima, lime nibindi bikoresho byingenzi birakomeye cyane, bishobora gutuma ibikoresho byingenzi bikina imikorere myiza. Nyamara, HPMC ifite imyitwarire idahwitse ifite fibre nyinshi yubusa, gukwirakwiza kungingo zidasimbuwe, gufata amazi nabi nibindi bintu, bikaviramo amazi menshi guhumeka mubihe byubushyuhe bwinshi. Nyamara, ibyo bita HPMC (ubwoko bwimvange) hamwe numwanda mwinshi biragoye guhuza hamwe, kubika amazi nibindi bintu bikaba bibi cyane. Iyo HPMC idafite ubuziranenge ikoreshejwe, ibibazo nkimbaraga nke zidatinze, igihe gito cyo gufungura, ifu, guturika, gutobora no kumena bizaterwa, ibyo bizongera ingorane zo kubaka kandi bigabanye cyane ubwiza bwinyubako.
