Ko te konutai carboxymethyl cellulose (CMC) he anionic, he mekameka tika, he wai-wairewa cellulose ether, he takenga o te cellulose taiao me te waikawa chloroacetic na te whakarereketanga matū.Ko tana otinga wai ko nga mahi o te whakapakeke, te hanga kiriata, te honohono, te pupuri wai, te whakamarumaru colloidal, te whakaemulsification me te whakatārewatanga, ka taea te whakamahi hei flocculant, chelating agent, emulsifier, thickener, wai pupuri wai, kaihoko rahi, kiriata hanga rauemi, etc ., e whakamahia nuitia ana i roto i te kai, te rongoa, te hikohiko, te pesticides, te hiako, te kirihou, te ta, te raima, te ahumahi matū o ia ra me etahi atu mara.
Ko te konutai carboxymethyl cellulose te tikanga he paura totoka, i etahi wa he kirikiri, he kiko, he ma, he kowhai marama ranei te tae, kaore he kakara motuhake, he matū matū macromolecular, he kaha te makuku, ka memeha ki roto i te wai, ki te wai hei hanga i te otinga viscous me te teitei. mārama.Korekore i roto i nga otinga waro whanui, penei i te waiwaro, te etera, te chloroform me te benzene, engari ka taea te rewa ki te wai, he puhoi te rewa tika i roto i te wai, engari he tino nui tonu te whakarewatanga, me te wairewa wai he tino pokey.Mārō i roto i te taiao whānui he ake pūmau, no te mea he etahi absorption wai me te haumākū, i roto i te taiao maroke, ka taea te tiaki mo te wa roa.
① Te tukanga whakaputa
1. Tikanga reo wai
Ko te tukanga wai-wao he tukanga whakaputa moata tonu i roto i te whakaritenga ahumahi o te konutai carboxymethyl cellulose.I roto i tenei tukanga, ka tauhohe te cellulose alkali me te kaihoko etherifying i roto i te wairewa wai kei roto nga katote hāora waikura kore utu, ka whakamahia te wai hei reo tauhohenga i roto i te tukanga tauhohenga, kaore he whakarewa waro.
2. Tikanga whakarewa
Ko te tikanga whakarewa he tikanga whakarewa pararopi, he tukanga whakaputa i whakawhanakehia i runga i te tikanga o te reo wai hei whakakapi i te wai me te whakarewa pararopi hei reo tauhohenga.He tukanga whakamaaramatanga me te whakaeera o te cellulose alkali me te waikawa monochloroacetic i roto i te whakarewa waro.E ai ki te nui o te reo tauhohenga, ka taea te wehea ki te tikanga pokepoke me te tikanga slurry kauhoe.Ko te nui o te whakarewa pararopi e whakamahia ana i roto i te tikanga pulping he nui ake i tera o te tikanga pokepoke, a ko te nui o te whakarewa pararopi e whakamahia ana i roto i te tikanga pokepoke ko te tauwehenga o te taumaha rōrahi o te nui o te cellulose, ko te nui o te whakarewa pararopi e whakamahia ana. i roto i te tikanga pulping ko te ōwehenga o te taimaha rōrahi o te nui cellulose.Ka rite te konutai carboxymethyl cellulose e te tikanga slurry kauhoe, ko te totoka tauhohenga kei roto i te slurry, i te ahua whakatārewatanga ranei i roto i te punaha, no reira ka kiia hoki te tikanga slurry kauhoe ko te tikanga whakatārewatanga.
