konutai carboxymethyl cellulosehe etera cellulose anionic he ma, he paku kowhai ranei he kowhatu kowhai he paura muka, he paura ma ranei te ahua, he kore kakara, he reka, he kore paitini; he ngawari ki te wairewa i roto i te wai makariri, i te wai wera ranei hei hanga i tetahi otinga maramara me tetahi pokey, he kupapa, he paku kawakore ranei te otinga; kare e rewa i roto i nga whakarewa pararopi penei i te waihano, te etera, te isopropanol, te acetone, me etahi atu, ka whakarewahia i roto i te 60% wai-wairewa wairewa acetone ranei.
He hygroscopic, he pumau ki te marama me te wera, ka heke te pokey me te piki ake o te pāmahana, ka pumau te otinga ki te uara PH o 2-10, he iti iho te uara PH i te 2, he ua totoka, he teitei ake te uara PH i te 10, ka heke te pokey. Ko te 227 ℃ te pāmahana whakapokao, ko te 252 ℃ te pāmahana warowaihā, me te mānukanuka o te mata o te 2% wairewa wai he 71mn/n.
Koinei te taonga a tinana o te konutai carboxymethyl cellulose, he pehea te pumau?
Ko nga ahuatanga o te tinana o te konutai carboxymethyl cellulose he tino pumau, no reira he paura ma, he kowhai ranei te roa. Ka taea te whakamahi i ona taonga kore tae, kakara me te kore-paitini i roto i nga waahi rereke, penei i te ahumahi kai, te ahumahi matū, me etahi atu; I te wa ano, he tino pai te whakarewatanga, ka taea te rewa i roto i te wai matao, i te wai wera ranei hei hanga i te reera, a ko te otinga kua whakakorehia he koretake, he ngoikore ranei te kawakore, na reira ka taea te whakamahi i roto i te tini o nga tono me te pai ake o nga paanga.
Na te mea he tino whakarewa te konutai carboxymethyl cellulose ka taea te whakamahi i nga wa maha i roto i te hanga me te oranga. Ae ra, he tino pumau ona ahuatanga tinana, a ko nga painga ka puta mai ka tino kitea, ka taea e tatou te ahua rereke.
