Ko te mararatanga o te carboxymethyl cellulose ka pirau te hua ki roto i te wai, no reira ko te mararatanga o te hua kua waiho hei huarahi hei whakatau i ana mahi.Kia ako ano tatou mo tena:
1) Ka taapirihia he wai nui ki te punaha whakamararatanga kua whiwhi, ka taea te whakapai ake i te whakamararatanga o nga matūriki colloidal i roto i te wai, a he mea tika kia kore e taea e te nui o te wai taapiri te whakakore i te colloid.
2) He mea tika ki te whakamarara i nga matūriki colloidal i roto i te reo kawe wai e uru ana ki te wai, e kore e rewa i roto i te wai-wairewa i roto i te wai-wairewa, kore wai ranei, engari me nui ake i te rōrahi o nga matūriki colloidal kia taea ai te tino marara. .he waipiro monohydric penei i te methanol me te ethanol, ethylene glycol, acetone, etc.
3) Me tapiri he tote wai-wairewa ki te wai kawe, engari kaore e taea e te tote te urupare ki te colloid.Ko tana mahi matua ko te aukati i te reera wairewa-wai mai i te hanga i te whakapiri, te coagulating ranei me te ua i te wa e okioki ana.Ko te nuinga o te whakamahi ko te konutai pūhaumāota me ētahi atu.
4) He mea tika ki te taapiri i tetahi kaihoko whakatārewa ki te wai kawe hei aukati i te ahuatanga o te rerenga reera.Ko te kaihoko whakatārewa matua ko te glycerin, hydroxypropyl methylcellulose, me etahi atu. Ko te kaihoko whakatārewa kia wairewa i roto i te kawe wai me te hototahi ki te colloid.Mo te carboxymethyl cellulose, mena ka whakamahia te glycerol hei kaihoko whakatārewa, ko te inenga o mua ko te 3%-10% o te wai kawe.
5) I roto i te tukanga o te alkaliization me te etherification, kia tāpiri cationic surfactants nonionic ranei, a kia rewa i roto i te kawe wai ki te kia hototahi ki colloids.Surfactants whakamahia noa he lauryl sulfate, glycerin Monoester, propylene glycol fatty acid ester, tona inenga ko te 0.05% -5% o te wai kawe.
