konutai carboxymethyl cellulose

Ko te konutai carboxymethyl cellulose (CMC-Na) he pärönaki carboxymethylated o te cellulose, a ko te tino nui o te katote katote kapia cellulose. 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.

2. Nga ahuatanga o te tinana me te matū

CMC-Na mo te paura poto, ma ki te kowhai kowhai kowhai, he matū kirikiri, he kiko kiko ranei, he kaha te hygroscopicity, he ngawari te wairewa i roto i te wai, he wai pokey teitei te otinga ina he koretake, he kawakore ranei. Ka mau ki nga rongoa, te marama me te wera. Engari, he iti te wera ki te 80°C, a, ki te whakamahana mo te wa roa ki runga ake i te 80°C, ka iti haere te pokey, ka kore e rewa ki te wai. Ko 1.60 te kiato whanaunga, ko te kiato o nga tawerewere he 1.59. Ko te 1.515 te taupū whakaata. Ka huri te parauri ina whakamahana ki te 190-205°C, ka warowai ina whakamahana ki te 235-248°C. Ko tona memehatanga ki te wai ka whakawhirinaki ki te tohu o te whakakapinga. Karekau he wairewa ki te waikawa me te waipiro, karekau he rerenga ki te tote. Ehara i te mea ngawari ki te ferment, he kaha te mana whakaemulsifying ki te hinu me te wax, ka taea te rongoa mo te wa roa.

3. Tono matua

Ka whakamahia nuitia i roto i te umanga hinu keri i te kaihoko maimoatanga paru, te hopii waihanga, te kaihanga hopi pararopi, te taarua kakano me te kakano kakano, te kaikawe colloidal wairewa mo nga hua matū o ia ra, te tackifier me te emulsifier mo te umanga rongoa, te whakamaroke mo te ahumahi kai Kaipupuri, whakapiri mo te uku. ahumahi, whakapiri ahumahi, kaihoko rahinga mo te ahumahi pepa, me etahi atu. Ka whakamahia hei flocculant i roto i te maimoatanga wai, te nuinga o te whakamahia i roto i te maimoatanga paru waipara, e taea te whakanui ake i te ihirangi totoka o te keke tātari.

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, te roa o te oranga o nga hua rimurapa, me te whakapai ake i te reka; na te mea he ahua o te kiri, he pai ki te hanga pai ake o te ra i roto i te kai, na reira ka taea te whakamahi ki te hanga tiēre me te tāmi; Ka taea hoki te whakamahi hei kiriata whakakikorua kai Ka whakahuihuihia te rauemi ki etahi atu momo whakakao ka pania ki runga i te mata o etahi kai, ka taea te pupuri i te kai kia hou tonu, a na te mea he mea kai, e kore e puta he kino. nga paanga ki te hauora o te tangata. 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.
