Zizindikiro zazikulu zoyezera mtundu wa CMC ndi kuchuluka kwa m'malo (DS) ndi chiyero. Kawirikawiri, katundu wa CMC ndi wosiyana pamene DS ndi yosiyana; kumtunda kwa mlingo woloweza m'malo, kusungunuka kwabwino, komanso kuwonekera bwino ndi kukhazikika kwa yankho. Malinga ndi malipoti, kuwonekera kwa CMC ndikwabwinoko pomwe kuchuluka kwa m'malo ndi 0.7-1.2, ndipo kukhuthala kwake kwamadzimadzi ndikokulirapo pomwe pH mtengo ndi 6-9.
Pofuna kuonetsetsa ubwino wake, kuwonjezera pa kusankha etherifying wothandizila, zinthu zina zimene zimakhudza mlingo wa m'malo ndi chiyero ayeneranso kuganiziridwa, monga mlingo ubale pakati alkali ndi etherifying wothandizira, nthawi etherification, dongosolo madzi zili, kutentha. , pH mtengo, ndende ya yankho ndi mchere.
Sodium carboxymethyl cellulose chimagwiritsidwa ntchito mafuta, chakudya, mankhwala, nsalu, papermaking ndi mafakitale ena, choncho n'kofunika kwambiri kuweruza molondola chiyero chake, ndi muyeso kuonetsetsa ntchito zotsatira zake, ndiye, Tingaone bwanji? kununkhiza, kukhudza, ndi kunyambita kuti aweruze kuyera kwake?
1. Sodium carboxymethyl cellulose yokhala ndi chiyero chachikulu imakhala ndi madzi ochuluka kwambiri, imatumiza kuwala kwabwino, ndipo kuchuluka kwake kwamadzi kumafikira 97%.
2. Zogulitsa zokhala ndi chiyero chambiri sizidzanunkhiza fungo la ammonia, wowuma ndi mowa, koma ngati zili zoyera, zimatha kununkhira zosiyanasiyana.
3. Choyera choyera cha sodium carboxymethyl cellulose ndi chowoneka bwino, ndipo kuchulukira kwakukulu ndi kochepa, kusiyana kwake ndi: 0.3-0.4 / ml; fluidity ya chigololo ndi bwino, dzanja kumverera ndi kulemera, ndipo pali kusiyana kwakukulu ndi maonekedwe oyambirira.
4. Kuchuluka kwa kloridi mu CMC kumawerengeredwa mu CL, pambuyo poyezedwa za CL, zomwe zili mu NaCl zitha kusinthidwa kukhala CL%*1.65
Pali ubale wina pakati pa CMC ndi chloride, koma osati zonse, pali zonyansa monga sodium glycolate. Pambuyo podziwa chiyero, zomwe zili mu NaCl zitha kuwerengedwa NaCl%=(100-kuyera)/1.5
Cl%=(100-kuyera)/1.5/1.65
Choncho, mankhwala omwe amanyambita lilime amakhala ndi kukoma kwa mchere wambiri, zomwe zimasonyeza kuti chiyero sichapamwamba.
Panthawi imodzimodziyo, sodium carboxymethyl cellulose yoyera kwambiri ndi chikhalidwe cha fiber, pamene mankhwala otsika kwambiri amakhala granular. Mukamagula chinthu, muyenera kuphunzira njira zingapo zosavuta zozindikiritsira. Kuonjezera apo, muyenera kusankha wopanga yemwe ali ndi mbiri yabwino, kuti khalidwe la mankhwala likhale lotsimikizika.
