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.

3. Tikanga slurry

Ko te tikanga slurry te hangarau hou ki te whakaputa konutai carboxymethyl cellulose.Ko te tikanga slurry e kore e taea anake te whakaputa i te parakore konutai carboxymethyl cellulose, engari ka whakaputa ano hoki i te konutai carboxymethyl cellulose me te tohu whakakapinga teitei me te whakakapinga kakahu.Ko te tikanga hanga o te tikanga slurry he penei te ahua: ko te penupenu miro kua kuia ki roto i te paura ka tukuna ki te miihini kawakore poutū e mau ana ki te waipiro isopropyl, ka taapirihia te wairewa konutai wai i te wa e whakaranuhia ana, a ko te pāmahana kawakore he tata ki te 20 ℃.I muri i te whakamaaramatanga, ka panaia te rauemi ki te miihini whakahiato poutū, ka taapirihia te wairewa waipiro isopropyl o te waikawa chloroacetic, a ko te pāmahana etherifying e tata ana ki te 65 ℃.E ai ki te whakamahinga hua motuhake me nga whakaritenga o te kounga, ka taea te whakatika i te kukū o te alkaliization, te wa o te alkaliization, te nui o te kaihoko etherifying me te wa etherification me etahi atu tawhā tukanga.

② Te whānuitanga tono

1. Ko te CMC ehara i te mea he pai te whakaemulsifying stabilizer me te thickener i roto i nga tono kai, engari he pai rawa atu te mīti me te rewa, ka taea te whakapai ake i te reka o te hua me te whakaroa i te wa rokiroki.

2. I roto i te hopii, ka taea te whakamahi CMC hei kaikawe anti-fouling redeposition, ina koa mo te papanga muka hydrophobic synthetic fabric anti-fouling redeposition pānga, tino pai ake i te muka carboxymethyl.

3. I roto i te keri hinu ka taea te whakamahi hei whakamarumaru i nga Poaka hinu hei whakapumau paru, he kaihoko pupuri wai, ko te nui o ia puna hinu ko te 2 ~ 3t Poaka papaku, Poka hohonu 5 ~ 6t.

4. Ka whakamahia i roto i te ahumahi pueru hei kaihoko rahi, te ta me te waikano slurry thickener, te tuhinga pueru me te whakaoti whakapakeke.

5. Ka whakamahia hei paninga anti-settling agent, emulsifier, dispersant, leveling agent, adhesive, ka taea e te wahi totoka o te peita te tohatoha i roto i te whakarewa, kia kore ai te peita e whakawhäitihia mo te wa roa, engari ka whakamahia ano hoki i roto i te putty. .

6. Ka rite ki te flocculant i roto i te tango o te konupūmā katote i te konutai gluconate atu whai hua, rite te whakawhitinga cation, te kaha whakawhiti o runga ki 1.6ml / g.

7. I roto i te ahumahi pepa e whakamahia ana hei kaihoko rahi pepa, ka taea te whakapai ake i te kaha maroke me te kaha maku o te pepa me te aukati hinu, te whakauru waituhi me te aukati wai.

8. Ka rite ki te hydrosol i roto i Paku, whakamahia rite te mātotoru mātotoru i roto i te toothpaste, tona horopeta ko te 5%.
