EipponCell® HEMC LH 6150M hydroxyethyl methyl cellulose e nka sebaka sa bohlokoa har'a li-additives tsa cellulose ether ka har'a sebaka sa seretse se omeletseng sa phofo.Hydroxyethyl methylcellulose ena e hlahisa mesebetsi e mengata ha e kenyelelitsoe mefuteng ea seretse.Karolo ea eona e ka sehloohong seretseng sa samente ke ho boloka metsi le ho teteana, e leng lintlha tsa bohlokoa tse bopang tšebeliso ea eona.
Ntle le mesebetsi ea eona ea mantlha, tšebelisano ea hydroxyethyl methyl cellulose le matrix ea samente e e fa bokhoni ba ho thusa.Tsena li kenyelletsa ho nolofatsa moea, ho chechisa nako ea ho beha nako, le ho matlafatsa matla a tlamahano, e leng se tlatselletsang phellong e felletseng ts'ebetsong ea seretse.
Ho boloka metsi ho hlaha e le motheo oa tšusumetso ea HEMC holim'a seretse.Sehlahisoa sena sa cellulose ether se fumana ts'ebetso ho mefuta e mengata ea lihlahisoa tsa seretse haholo-holo ka lebaka la bokhoni ba eona ba ho boloka metsi.Tekanyo ea ho boloka metsi e fihletsoeng ke HEMC e tlameletsoe ka mokhoa o rarahaneng ho lintlha tse kang viscosity, tekanyo ea ho fetola, le boholo ba likaroloana, tseo ka kakaretso li tlatsetsang katlehong ea eona.
Ha e sebelisoa e le motenya, matla a hydroxyethyl methyl cellulose a hokahana ka mokhoa o rarahaneng le liparamente tse kang degree of substitution, particle size, viscosity, le degree of modification.Ha re bua ka mokhoa o pharaletseng, ha tekanyo ea phetoho le viscosity ea cellulose ether e phahame, e kopantsoe le boholo ba likaroloana tse nyenyane, phello ea ho teteana e ba e hlakileng haholoanyane.
