Methyl celluloseKo te tikanga te whakapoto o te konutai carboxymethyl cellulose, no te ahua o te polyanionic pūhui me te wairewa pai. I roto ia ratou, methyl cellulose te nuinga ngā methyl cellulose m450, whakarerekētia methyl cellulose, kai Grade methyl cellulose, hydroxymethyl cellulose, me ētahi atu, Kei te nuinga o whakamahia i roto i te whānuitanga o ngā ahumahi, te nuinga whakamahia i roto i te hanga, uku, kai, pākahiko, papermaking, coatings, pharmaceuticals, maina, hinu keri me etahi atu ahumahi. He mea tika kia whakahuahia i roto i te waahi o te ciment, ko te methylcellulose he kaha whakamuri i runga i nga ranunga moata, he mea hoki na te ahua ahurei o te methylcellulose.
Ka rite ki te roa-mekameka whakakapi cellulose, konutai carboxymethylcellulose ake e pā ana ki 27% ~ 32% o ona rōpū hydroxyl i roto i te ahua o ngā rōpū methoxy, me te tohu o te polymerization o ngā kōeke rerekē okonutai carboxymethylcellulosehe rereke ano. Ko te taumaha ngota i te nuinga o te waa mai i te 10,000 ki te 220,000 Da, ko te tohu whakakapinga matua ko te maha toharite o nga roopu methoxy, he rereke nga waeine anhydroglucose e hono ana ki te mekameka.
Ko te konutai carboxymethyl cellulose i tenei wa e whakamahia nuitia ana i roto i etahi whakaritenga mo te kaupapa, tae atu ki nga mea whakapaipai me te methyl cellulose kai-kore, ko te tikanga he kore paitini, he kore whakaraerae, he kore e whakapataritari. Ko te Methyl cellulose Su he mea kore-caloric,
