MC ni methyl selile, ikozwe muri selile ifata ipamba inoze hamwe na alkali, ukoresheje chloride ya methane nkabakozi bahura, kandi inyuze mu ruhererekane. Mubisanzwe, urwego rwo gusimburwa ni 1.6 ~ 2.0, kandi kwikebana nabyo bitandukanye nuburyo butandukanye bwo gusimburwa. Ni iya Not-ionic selile.
. Mubisanzwe, niba amafaranga yongeyeho ari manini, igorofa ni nto, kandi viscometity nini, igipimo cyo kugumana amazi ni kinini. Muri bo, ingano yo kongenge ifite ingaruka zikomeye ku gipimo cyo kugumana amazi, kandi urwego rwa vicosity ntabwo ruringaniye mu rwego rwo kugabana amazi. Igipimo cyo gusebanya cyane cyane giterwa nurwego rwo guhindura hejuru yubuso bwa selire hamwe nibyiza. Muri erebire yavuzwe haruguru, Methyl selile na hydroxypropyl methyl Methyl ifite ibiciro byamazi menshi.
(2) methylcellsellse irashonga mumazi akonje, kandi bizaba bigoye gushonga mumazi ashyushye. Igisubizo cyacyo gihamye cyane murwego rwa PH = 3 ~ 12. Ifite neza hamwe nigitako, Guar gum, nibindi nibindi byinshi. Iyo ubushyuhe bugera ku bushyuhe bwa gelale, pelation ibaho.
. Mubisanzwe, hejuru yubushyuhe, ihohoterwa rikabije. Niba ubushyuhe bwa minisiteri burenze 40 ° C, ugumana amazi ya methyl selile bizagabanuka cyane, bigira ingaruka zikomeye kubakwa kuri minisiteri.
. "Imyitozo" ikubiyemo imbaraga zifatika zumvaga hagati yigikoresho cyo gusabana nurukuta, ni ukuvuga ko kurwanya minisiteri. Kubungabunga ni byinshi, kurwanya imisiteri ari nini, kandi imbaraga zisabwa n'abakozi mu buryo bwo gukoresha nacyo ni kinini, kandi imikorere y'ubwubatsi ya minisiteri irakennye. Methyl Adherilose Ashesion ari kurwego ruciriritse mubicuruzwa bya selile.
HPMC ni hydroxypropyl methylcellse, aricyo selile itari ionic ivanze ku ipamba itunganijwe nyuma ya alkalide na methyl nkabashitsi, kandi binyuze murukurikirane rwibitekerezo. Urwego rwo gusimbuza ni 1.2 ~ 2.0. Imitungo yayo iratandukanye kubipimo bitandukanye bya uburyo na hydroxyproppopyl.
. Ariko ubushyuhe bwa pelale mumazi ashyushye burenze ivya methyl selile. Kudakemura mumazi akonje nabyo birateye imbere cyane ugereranije na methyl selile.
. Ubushyuhe bugira ingaruka kandi ku rubyiruko, uko ubushyuhe bwiyongera, vicosity igabanuka. Ariko, viscosity yayo yo hejuru ifite ingaruka zo hepfo kurenza methyl selile. Igisubizo cyacyo kirahagaze mugihe kibitswe mubushyuhe bwicyumba.
. Amazi ya Caustic Soda namazi ntabwo afite ingaruka nke kubikorwa byayo, ariko alkali irashobora kwihutisha iseswa ryayo kandi ryongerera ubuyobe. HydroxyPropyl Methylcellse irahamye muminyuhuri isanzwe, ariko iyo kwibanda ku gisubizo cyumunyu hejuru, viscogity ya hydroxyPropyl methylcellse igisubizo gikunda kwiyongera.
