Sodium carboxymethyl celluloseis an anionic cellulose ether ine white or little yellow flocculent fibrous powder or white powder pachimiro, isinganhuhwi, isinganakidze uye isina chepfu; nyore soluble mumvura inotonhora kana inopisa kuti iite sarudzo yakajeka ine imwe viscosity, mhinduro yacho haina kwazvakarerekera kana zvishoma alkaline; insoluble muorganic solvents senge ethanol, ether, isopropanol, acetone, nezvimwewo, soluble mu 60% mvura-ine ethanol kana acetone solution.
Iine hygroscopic, yakagadzikana kuchiedza uye kupisa, viscosity inoderera nekuwedzera kwekushisa, mhinduro inogadzikana pa PH kukosha kwe 2-10, PH kukosha yakaderera kupfuura 2, kune kunaya kwakasimba, uye PH kukosha kwakakwirira kudarika 10, viscosity inoderera. The discoloration tembiricha i227 ℃, iyo carbonization tembiricha i252 ℃, uye tension yepasi ye2% aqueous solution i71mn/n.
Ichi ndicho chivakwa chesodium carboxymethyl cellulose, yakagadzikana sei?
Iyo yenyama yesodium carboxymethyl cellulose yakagadzikana zvakanyanya, saka inopa inogara kwenguva refu chena kana yero poda. Iyo isina ruvara, isina kunhuhwirira uye isina-chepfu zvivakwa zvinogona kushandiswa muzviitiko zvakasiyana, senge indasitiri yechikafu, indasitiri yemakemikari, nezvimwe; Panguva imwecheteyo, ine yakanyanya kunaka solubility uye inogona kunyungudutswa mumvura inotonhora kana mvura inopisa kuti iite gel, uye mhinduro yakanyungudutswa haina kwayakarerekera kana isina simba alkaline, saka inogona kushandiswa mumhando dzakasiyana siyana uye inounza mhedzisiro iri nani.
Izvo chaizvo nekuti sodium carboxymethyl cellulose inonyungudika zvekuti inogona kushandiswa mune dzakawanda zviitiko mukugadzira uye hupenyu. Zvechokwadi, maitiro ayo emuviri akanyatsogadzikana, uye zvikomborero zvazvingaunza zvichava pachena zvakanyanya, zvichitibvumira kunakidzwa nekunzwa kwakasiyana.
