Carboxymethyl Cellulose
Te ahua:paura ma, miraka ranei
Ngā āhuatanga ā-tinana:he pärönaki cellulose me ngä röpü carboxymethyl (-CH2-COOH) e herea ana ki etahi o nga roopu hydroxyl o nga monomers glucopyranose e hanga ana i te tuara cellulose.Ka kiia ano ko CMC, Carboxymethyl.Cellulose konutai, konutai tote o Caboxy Methyl Cellulose.Ko te CMC tetahi o nga polyelectrolyte wairewa wai nui.Ka taea te rewa i roto i te wai, te wairewa i roto i te waipiro, te waihano, te benzene, te chloroform me etahi atu whakarewa pararopi.He ātete ki te hinu kararehe me te hinu huawhenua me te kore e pa ki te whakamarama.

Taupānga: Ko te CMC (e kiia ana ko te "ahumahi paura paura") he ahua o te cellulose ether i roto i te wai-wairewa muka pärönaki, e whakamahia whānuitia ana mo nga ahumahi o te tukatuka kai, te inu waikawa lactic me te toothpaste, me etahi atu, he mahi nui. i roto i ia ahumahi, hokohoko ranei hei whakaemulsifier, kaihoko rahi .stabilizer, thickener, retarder, kiriata o mua, dispersing agent, suspending agent, adhisive, mercerizing agent, lustering agent and color fixing agent, etc. .
