Ina tae mai ki te whakarewatanga o te methyl cellulose, ko te nuinga o te korero mo te whakarewatanga o te konutai carboxymethyl cellulose.
Ko te konutai carboxymethyl cellulose he ma, he kowhai kowhai ranei te muka paura, he hongi, he kore reka.He ngawari te wairewa i roto i te wai makariri, wera ranei, ka hanga he otinga maramara me tetahi pokey.
He aha te whakarewatanga?Inaa, e pa ana ki te papatipu o te wairewa kua memeha e tetahi matū totoka i roto i te ahua kukū i roto i te 100g o te whakarewa i tetahi pāmahana.Ko te memehatanga tenei.Ko te whakarewatanga o te methyl cellulose e pa ana ki nga waahanga e rua.I tetahi taha, ka whakawhirinaki ki nga ahuatanga o te carboxymethyl cellulose, a, i tetahi atu ringa, he iti te hononga ki te pāmahana o waho, te makuku, te pehanga, te momo whakarewa, me etahi atu. te pāmahana, a ka piki ake i te pikinga o te pāmahana.
E toru nga tikanga mo te whakakore i te methylcellulose:
1. tikanga makuku whakarewa organic.Ko te nuinga o tenei tikanga ko te whakamaarama, te whakamakuku ranei i nga whakarewa pararopi MC penei i te ewaro me te ethylene glycol i mua, katahi ka taapirihia he wai kia memeha.
2. Tikanga wai wera.Na te mea he koretake te MC ki te wai wera, ka taea te marara o te MC ki te wai wera i te wa tuatahi.I te whakamatao, ka taea te whai i nga tikanga e rua e whai ake nei:
(1) Ka taea e koe te taapiri i te nui o te wai wera ki te ipu ka whakamahana ki te 70°C.I āta tāpirihia te MC me te pōturi o te kōrori, ā, ka hanga he slurry, kātahi ka whakamatao mā te kōrori.
(2) Tāpirihia te 1/3 o te nui o te wai e hiahiatia ana ki roto i te ipu kua whakaritea, whakamahana ki te 70°C, ka whakamararatia te MC kia rite ki te tikanga kua whakahuahia ake nei, katahi ka whakarite i te slurry wai wera;katahi ka tapiri ki te wai matao Haere ki te slurry, kia pai te whakaoho kia whakamataohia te ranunga.
3. Tikanga whakaranu paura.Ko tenei tikanga ko te whakamarara i nga matūriki paura MC me nga kai paura rite ma te whakaranu maroke, katahi ka taapirihia te wai kia memeha.
