He aha te hydroxyethyl cellulose?
Hydroxyethyl cellulose (hec), he ma, he maama ranei te kowhai, he ngoikore-kore-paitini ranei, kua oti i a koe te whakamahi i te oriwa. Mai i te mea he pai te tipu o Hec mo te matotoru, te aukati, te marara, te hono, te whakakii, te kakano, te kakano me te polymer me etahi atu mara.
Kei te whakamahia whānuitia te celluxyethyl cellulose i te umanga paninga, kia titiro tatou me pehea te mahi o nga koti:
Ka ahatia i te wa e tutuki ai te peita hydroxyetyl e pa ana ki te peita i te wai-wai?
I te mea he papaa kore-Ionic, te hydroxyethyl cellusies e whai ake nei hei taapiri, te aukati, te herea, te marara, te pupuri i te wai me te pupuri i te wai tiaki.
Ko te Hec he rewa i roto i te wai wera, te wai makariri ranei, te kohua nui ranei, kia kore ai e ua te whanui, me nga ahuatanga rereke, me te waiora kore-waiariki;
Ko te mana pupuri wai e rua nga wa teitei rite te cellulose methyl, he pai ake te ture rere;
Ehara i te mea ehara i te Ionic ka taea te whai hononga ki te whānuitanga o etahi atu o nga polyment wai-wai, nga papaa, me nga tai. Ko te tino matotoru o te collloidal mo nga otinga electrolyte nui;
I whakaritea ki te cellulose methyl mohio me te hydroxypropyl cellulose, ko te kaha o te marara o te hec, engari ko te kaha tiaki whakamarumaru ko te kaha tiaki.
Mai i te mea ko te CellloxyethyL-a-papa-a-papa he paura, he totoka ranei, me whai ake nga tohu e whai ake nei i te wa e whakarite ana i te waipiro o te hauhautanga hydroxyetyl:
(1) I mua i te taapiri i te CellDroxyethyl Cellulose, me whakaohooho tonu kia tae noa ki te otinga o te otinga me te maarama.
(2) Me ata haere tonu ki te tank whakaranu, kaua hoki e maka he moni nui, kaua ranei e maka atu i te celldroxyethyl cellulose ki roto i te tank whakaranu.
(3) Ko te pāmahana wai me te uara ph i roto i te wai he hononga nui ki te whakakorenga o te cellloxyhyl cellulose, me utu motuhake.
(4) Kaua e tapiri etahi taonga konutai ki te ranunga i mua i te hydroxyethyl paura ka pania ki te wai. Te whakaara i te pH i muri i te maroke ka awhina i te memeha.
(5) Ki te taea, tāpiri Antifungal Ant Antifengal i mua.
(6) Ka whakamahi ana i te ahua o te hydroxyethyl, ko te kukume o te waipiro whaea kaua e teitei ake i te 2.5-3% (ma te taumaha), kaare te uaua ki te whakahaere.
