Methyl cellulose ndi chidule cha sodium carboxymethyl cellulose. Amagwiritsidwa ntchito makamaka pazakudya, zomangamanga, mankhwala, zoumba, mabatire, migodi, zokutira, kupanga mapepala, kutsuka, mankhwala otsukira mano tsiku lililonse, kusindikiza nsalu ndi utoto, kubowola mafuta, ndi zina zambiri m'munda. Ntchito yayikulu ndikuchita ngati chowonjezera, chosungira madzi, chomangira, chopaka mafuta, choyimitsa, emulsifier, chonyamulira zinthu zamoyo, matrix a piritsi, ndi zina zambiri. Kodi methyl cellulose iyenera kugawidwa bwanji pakugwiritsa ntchito?
1. Methylcellulose palokha ndi ufa woyera wouma, womwe sungagwiritsidwe ntchito mwachindunji pamakampani. Iyenera kusungunuka m'madzi kaye kuti ipange guluu wowonekera bwino isanasakanizidwe ndi matope kenako ndikugwiritsidwa ntchito pochiza mawonekedwe, monga kumata matailosi.
2. Kodi methyl cellulose ndi chiyani? Ufa: madzi ayenera kukonzedwa panthawi imodzi malinga ndi chiwerengero cha 1: 150-200, ndiyeno amatsitsimutsidwa, ndikuwonjezera PMC ufa wouma pamene akuyambitsa, ndipo angagwiritsidwe ntchito patatha pafupifupi ola limodzi.
3. Ngati methyl cellulose imagwiritsidwa ntchito pochiza konkriti, chiŵerengero cha guluu chiyenera kutsatira → guluu: simenti = 1:2.
4. Ngati methyl cellulose ikugwiritsidwa ntchito ngati matope a simenti kuti asaphwanyeke, guluu liyenera kutsatiridwa → guluu: simenti: mchenga = 1:3:6.
Tiyenera kulabadira zovuta zina mukamagwiritsa ntchito methyl cellulose:
1. Musanagwiritse ntchito methyl cellulose, choyamba muyenera kuyang'ana mafotokozedwe ndi mitundu yake. Mitundu yosiyanasiyana imagwiritsa ntchito njira zosiyanasiyana: pamene pH> 10 kapena <5, kukhuthala kwa guluu kumakhala kochepa. Ntchitoyi imakhala yokhazikika kwambiri pamene pH = 7, ndipo kukhuthala kudzakwera mofulumira pamene kutentha kuli pansi pa 20 ° C; pamene kutentha kuli pamwamba pa 80 ° C, colloid idzasinthidwa pambuyo pa kutentha kwa nthawi yaitali, koma mamasukidwe ake amatsika kwambiri.
2. Methyl cellulose ikhoza kukonzedwa ndi madzi ozizira kapena madzi otentha molingana ndi chiwerengero chokhazikika. Pokonzekera, muyenera kuwonjezera madzi pamene mukuyambitsa. Kumbukirani kuwonjezera madzi onse ndi ufa wouma wa PMC nthawi imodzi. Ndikoyenera kudziwa kuti gawo loyambira lomwe liyenera kumangidwa liyenera kutsukidwa pasadakhale, ndipo zinyalala zina, madontho amafuta, ndi zotayirira ziyenera kuthetsedwa munthawi yake.
