Carboxymethyl cellulose CMC, sodium carboxymethyl starch (CMS), mutengo wacho wakachipa (kubva pakuita kwechigadzirwa chacho, CMC igiredhi rakaderera pane Fuying HPMC), carboxymethyl cellulose inoshandiswa kune yakaderera-giredhi putty poda yemukati madziro Pakati pavo. , kuchengetwa kwemvura uye kugadzikana kwakanyanya kuipa kupfuura iyo yehydroxypropyl methylcellulose, saka haigoni kushandiswa mumvura isina mvura putty uye kunze kwekupisa kwekushisa kusanganiswa kwakaoma.
Vanhu vazhinji vanofunga kuti maserulosi aya ane alkaline, uye simende uye lime calcium poda zvakare ane alkaline, uye vanofunga kuti anogona kushandiswa pamwe chete, asi carboxymethyl cellulose uye sodium carboxymethyl starch haisi chinhu chimwe chete, uye chloroacetic acid inoshandiswa mukugadzira kwavo. Iine acidic, uye zvinhu zvakasara mukugadzirwa kwe cellulose zvinopindirana nesamende uye lime calcium powder, saka hazvigoni kusanganiswa. Vazhinji vagadziri vakatambura kurasikirwa kukuru nekuda kweizvi, saka kutarisisa kunofanirwa kubhadharwa. Kushandiswa kwecarboxymethyl cellulose uye hydroxypropyl methyl cellulose kwakangofanana, asi mabasa avo akasiyana zvakanyanya, uye zviratidzo zvehunyanzvi zvezviviri zviri kure. Iwo makuru ezvigadzirwa zveaviri akafanana akacheneswa donje, asi zvigadzirwa zvekubatsira, zvigadzirwa zvekugadzira, uye kuyerera kwemaitiro zvakasiyana. Zvigadzirwa zvekugadzira uye maitiro ehydroxypropyl methylcellulose zvakanyanya kuomarara. Iwo maviri haasi maitiro ekugadzira zvachose, uye zvimwe zvishongedzo zvakasiyanawo, saka mashandisirwo acho akasiyana. Izvo hazvigone kutsiviwa, uye hazvigone kusanganiswa pamwe chete kuti zvideredze mutengo.
Hydroxypropyl methylcellulose (hpmc) ine yakagadzikana makemikari zvinhu, mildew kuramba, yakanakisa kuchengetedza mvura uye thickening mhedzisiro, uye haina kukanganiswa nepH shanduko. Iyo viscosity ye100,000 inokodzera putty poda, uye viscosity ye150,000 kusvika 200,000 inokodzera putty poda. Mudhaka, inonyanya kuwedzera nzvimbo yekuenzanisa uye yekuvaka, uye inogona kuderedza huwandu hwesimende.
Basa nderekuti dhaka resimende rine nguva yekusimba, uye rinoda kuchengetedzwa panguva yekusimba, uye rinoda kupihwa nemvura kuti rirambe rakanyorova. Nekuda kwekuchengetedza kwemvura kweselulosi, mvura inodiwa kune simende dhaka solidification inovimbiswa kubva mukuchengetwa kwemvura ye cellulose, saka iyo yekusimbisa mhedzisiro inogona kuwanikwa pasina kugadzirisa.
