Te whakamahinga o te konutai carboxymethyl cellulose me te hydroxyethyl cellulose i roto i nga hua matū o ia ra

Ko te konutai Carboxymethylcellulose (CMC-Na) he matū waro, he pärönaki carboxymethylated o te cellulose, me te tino kapia cellulose katote. Ko te konutai carboxymethyl cellulose he pūhui polymer anionic i whakaritea ma te tauhohe i te cellulose taiao me te kawakawa me te waikawa monochloroacetic, me te taumaha ngota mai i te tini mano ki te miriona. Ko te CMC-Na he paura kirikiri, he paura maramara ranei, he kore kakara, he reka, he hygroscopic, he ngawari ki te marara ki te wai kia puta he otinga colloidal marama.

I te wa e noho koretake ana, he kawakore ranei, ko te wairewa he wai pokey teitei. Ka mau ki nga rongoa, te marama me te wera. Heoi, he iti te wera ki te 80°C, a ki te whakamahana mo te wa roa ki runga ake i te 80°C, ka heke te pokey ka kore e rewa ki te wai.

Ko te konutai carboxymethyl cellulose he momo whakamaaru. Na te pai o nga ahuatanga o te mahi, kua whakamahia nuitia i roto i te ahumahi kai, me te whakatairanga i te tere me te hauora o te ahumahi kai ki tetahi waahanga. Hei tauira, na te kaha o te whakapakeke me te whakaemulsifying, ka taea te whakamahi ki te whakapumau i nga inu miraka pē me te whakanui ake i te pokey o te punaha miraka pē; na te kaha o te wai me te rehydration, ka taea te whakamahi ki te whakapai ake i te kai rimurapa penei i te taro me te taro koromamao. te kounga, whakaroa i te oranga o nga hua rimurapa me te whakanui i te reka.

Na te mea he paanga o te reera, he pai ki te kai kia pai ake te hanga reera, na reira ka taea te whakamahi ki te hanga tiēre me te tāmi; ka taea hoki te whakamahi hei papanga paninga kai, ka whakahuihuitia ki etahi atu mea whakakatakata, ka horahia ki runga i etahi papa kai, ka taea e ia te pupuri i te kai kia hou tonu, a, na te mea he mea kai, e kore e puta he kino ki te tangata. hauora. Na reira, ko te CMC-Na te kai-koeke, hei taapiri kai pai, e whakamahia nuitia ana i roto i te hanga kai i roto i te umanga kai.

Ko te Hydroxyethylcellulose (HEC), te tauira matū (C2H6O2)n, he ma, he kowhai marama ranei, he hongi, he kikokore, he paura totoka kore-paitini, he mea hanga mai i te cellulose alkaline me te ethylene oxide (he chlorohydrin ranei) I whakaritea ma te tauhohenga whakaeterera, no te kore- te katote wairewa cellulose ethers. Na te mea he pai nga ahuatanga o te HEC mo te whakamaroke, te whakatarewa, te whakamarara, te whakaemulsifying, te here, te hanga kiriata, te tiaki i te makuku me te whakarato colloid tiaki.

He ngawari te whakarewa ki te wai i te 20°C. Karekau ki roto i nga whakarewa pararopi noa. Kei a ia nga mahi o te whakapakeke, te aukati, te here, te whakaemulsifying, te whakamarara, me te pupuri i te makuku. Ka taea te whakarite otinga i roto i nga awhe pokey rereke. He tino pai te wairewa tote mo nga electrolytes.

He paku rereke te pokey i te awhe o te uara PH 2-12, engari ka heke te pokey ki tua atu i tenei awhe. Kei a ia nga ahuatanga o te matotoru, te whakatarewa, te here, te whakaemulsifying, te marara, te pupuri i te makuku me te tiaki i te colloid. Ka taea te whakarite otinga i roto i nga awhe pokey rereke.
