Sodium carboxymethyl cellulose (CMC-Na) inotorwa necarboxymethylated ye cellulose uye ndiyo inonyanya kukosha ionic cellulose chingamu. Sodium carboxymethyl cellulose inowanzoita anionic polymer compound yakagadzirwa nekuita selulosi yechisikigo ine caustic alkali uye monochloroacetic acid, ine huremu hwemamorekuru kubva kuzviuru zvakati kusvika kumamiriyoni. CMC-Na ichena fibrous kana granular poda, isinganhuhwi, isinganakidze, hygroscopic, iri nyore kupararira mumvura kuita inoonekera colloidal mhinduro.

2. Muviri uye makemikari zvinhu
CMC-Na kwenguva pfupi, chena kusvika yakachenuruka yero hupfu, granular kana fibrous substance, yakasimba hygroscopicity, nyore soluble mumvura, uye mhinduro iri high viscosity fluid kana isina kwayakarerekera kana alkaline. Yakagadzikana kumishonga, chiedza uye kupisa. Zvisinei, kupisa kunogumira ku80 ° C, uye kana inopisa kwenguva yakareba kupfuura 80 ° C, viscosity ichaderera uye inenge isingagadziriswi mumvura. Density yaro ndeye 1.60, uye hukama hwehukama hwemaflakes ndeye 1.59. Iyo refractive index ndeye 1.515. Inoshanduka kuva shava kana ichipisa kusvika 190-205°C, uye carbonizes kana yapiswa kusvika 235-248°C. Kunyungudika kwayo mumvura kunoenderana nehuwandu hwekutsiviwa. Insoluble mu acid nedoro, hapana kunaya kana munyu. Haisi nyore kuvirisa, ine simba rakasimba rekuemurisa mafuta nenamo, uye inogona kuchengetwa kwenguva yakareba.
3. Main application
Inoshandiswa zvakanyanya muindasitiri yemafuta kuchera madhaka ekurapa, yekugadzira dhizaini, organic detergent muvaki, machira anodhinda uye dhayi saizi ajenti, inonyungudika nemvura colloidal tackifier yemazuva ese emakemikari zvigadzirwa, tackifier uye emulsifier yeindasitiri yemishonga, thickener yeindasitiri yechikafu Thickener, adhesive yeceramic. indasitiri, indasitiri paste, sizing agent yeindasitiri yemapepa, etc. Inoshandiswa senge flocculant mukurapa kwemvura, inonyanya kushandiswa mumarara emarara emarara, ayo anogona kuwedzera iyo yakasimba yemukati yesefa keke.
Sodium carboxymethyl cellulose zvakare imhando yekukora. Nekuda kwemaitiro ayo akanaka ekushanda, yakashandiswa zvakanyanya muindasitiri yezvekudya, uye yakasimudzira kukurumidza uye kune hutano kusimudzira kweindasitiri yezvekudya kusvika pamwero wakati. Semuenzaniso, nekuda kwekumwe kukora uye emulsifying mhedzisiro, inogona kushandiswa kudzikamisa yogurt zvinwiwa uye kuwedzera viscosity yeyoghurt system; nekuda kwehumwe hydrophilicity uye rehydration zvivakwa, inogona kushandiswa kuvandudza manwiro epasta senge chingwa nechingwa chakabikwa. kunaka, kuwedzera hupenyu hwesherufu yezvigadzirwa zvepasta, uye kunatsiridza kuravira; nokuti ine imwe gel effect, inobatsira pakugadzirisa zviri nani gel muzvokudya, saka inogona kushandiswa kugadzira jelly uye jam; inogona zvakare kushandiswa seyakabikwa yekuputira firimu Nyaya yacho inosanganiswa nemamwe makobvu uye inoshandiswa pamusoro pezvimwe zvikafu, izvo zvinogona kuchengetedza chikafu chitsva kusvika pamwero mukuru, uye nekuti icho chinhu chinodyiwa, hachizokonzeresa chakaipa. zvinokanganisa hutano hwevanhu. Naizvozvo, chikafu-giredhi CMC-Na, seyakanaka chekuwedzera chikafu, chinoshandiswa zvakanyanya mukugadzira chikafu muindasitiri yechikafu.
