Methyl Hydroxyethyl Cellulose (MHEC) ni ether ya selile idafite ionic ikoreshwa cyane mubikoresho byubwubatsi. Irashobora gushonga mumazi ashyushye cyangwa akonje kugirango ibe igisubizo kiboneye hamwe nubwiza bwihariye. Imiterere ya methyl hydroxyethyl selulose na methylcellulose irasa, ariko kuba hydroxyethyl ituma selile ya MHEC irushaho gushonga mumazi, igisubizo kirahuza numunyu kandi gifite ubushyuhe bwinshi bwo kwegeranya.
Gusaba:
Ifu ya selile ya MHEC ikoreshwa cyane mubikorwa byo kubaka. Kurugero, irashobora gukoreshwa mugufata tile, kuzuza hamwe, kwipimisha ubwayo, plaster, skim coat, amarangi hamwe na coatings, nibindi. Nka ether ya selile itari ionic, ifu ya HMEC igira ingaruka nziza kandi ikabyimbye mumarangi, irashobora gutuma irangi ritanga imyambarire myiza. Amavuta ya selile ya MHEC arashobora kunoza cyane imikorere ya minisiteri (nko kuzamura imbaraga zububiko bwa minisiteri, kugabanya kwinjiza amazi, no kongera anti-sag ya minisiteri), ifasha mukuzamura imikorere myiza.
Usibye inganda zubaka, methyl hydroxyethyl selulose nayo ikoreshwa mubucuruzi bwibiribwa, imiti ya buri munsi, nizindi nzego. Mu nganda z’ibiribwa, selile ya HEMC ikoreshwa nka adhesion, emulisation, gukora firime, kubyimba, guhagarika, gutatanya, ibikoresho byo gufata amazi, nibindi. Imiti ya buri munsi, ikoreshwa nkiyongera kumiti yinyo, kwisiga, no kwisiga.
Ipaki: 25 kgs / igikapu cyangwa nkuko ubisabye.
Ububiko: Bika ahantu hafite umwuka, humye.
Ibipimo byakozwe: Ibipimo mpuzamahanga.
