Te konutai carboxymethyl celluloseHe etera cellulose anionic me te paura muka mā, he kōwhai paku rānei te āhua, kāore he kakara, kāore he reka, kāore hoki he paitini; he ngāwari ki te wairewa i roto i te wai matao, i te wai wera rānei hei hanga i tētahi otinga mārama me te matotoru motuhake, he kūpapa, he paku kawakore rānei te otinga; kāore e wairewa i roto i ngā whakarewa waro pērā i te etanoru, etera, isopropanol, acetone, me ētahi atu, ka wairewa i roto i te 60% wai etanoru, i te otinga acetone rānei.
He waiora, he pumau ki te mārama me te wera, ka heke te matotoru i te pikinga o te pāmahana, he pumau te otinga i te uara PH o te 2-10, he iti iho te uara PH i te 2, he totoka te ua, ā, he teitei ake te uara PH i te 10, ka heke te matotoru. Ko te pāmahana whakakorenga he 227℃, ko te pāmahana whakawaro he 252℃, ā, ko te kukū mata o te otinga wai 2% he 71mn/n.
Koinei te āhuatanga ā-tinana o te konutai carboxymethyl cellulose, he pēhea tōna pumau?
He tino pumau ngā āhuatanga ā-tinana o te konutai carboxymethyl cellulose, nō reira he paura mā, he paura kōwhai rānei e mau tonu ana mō te wā roa. Ka taea te whakamahi i ōna āhuatanga kore tae, kore kakara, kore paitini hoki i ngā wā maha, pērā i te umanga kai, te umanga matū, me ētahi atu; i te wā anō, he tino pai te wairewa, ā, ka taea te rewa ki te wai matao, ki te wai wera rānei hei hanga i te kirikiri, ā, he kūpapa, he kawakore ngoikore rānei te wairewa rewa, nō reira ka taea te whakamahi i roto i te whānuitanga o ngā tono, ā, he pai ake ngā hua.
Nā te mea he tino wairewa te konutai carboxymethyl cellulose, ka taea te whakamahi i ngā wā maha i roto i te hanga me te oranga. He pono, he tino pumau ōna āhuatanga ā-tinana, ā, ka tino kitea ngā painga ka puta mai, ka taea ai e tātou te pārekareka ki tētahi kare rerekē.
