Sodium carboxymethyl cellulose (CMC-Na kwenguva pfupi) yakakosha mvura-inonyungudika yepolymer komboni, inoshandiswa zvakanyanya mukudya, mishonga, zvizorwa, machira, kugadzira mapepa uye maindasitiri ekuvaka. Sechinowanzo shandiswa thickener, stabilizer uye emulsifier,
1. Kusarudzwa kwezvinhu zvakasvibiswa uye kutonga kwehutano
Paunenge uchisarudza CMC-Na, iwe unofanirwa kuterera pakusarudza yakakwirira-kuchena zvigadzirwa. Zviratidzo zvemhando yechigadzirwa zvinosanganisira dhigirii rekutsiva, viscosity, kuchena uye pH kukosha. Iyo dhigirii yekutsiva inoreva zviri mukati mecarboxylmethyl mapoka muCMC-Na molecule. Kazhinji, iyo yakakwirira dhigirii yekutsiva, zviri nani kunyungudika. Viscosity inosarudza kuenderana kwemhinduro, uye iyo yakakodzera viscosity giredhi inofanirwa kusarudzwa zvinoenderana nezvinodiwa chaizvo zvekushandisa. Uye zvakare, ita shuwa kuti chigadzirwa hachina hwema, hapana tsvina, uye chinosangana nematanho akakodzera, akadai segiredhi rekudya, giredhi remishonga, nezvimwe.
2. Kudiwa kwehutano hwemvura pakugadzirira mhinduro
Kana uchigadzira CMC-Na mhinduro, mhando yemvura inoshandiswa yakakosha zvikuru. Zvinowanzo kudiwa kushandisa mvura yakachena kana deionized mvura kudzivirira pesvedzero tsvina mumvura pamusoro CMC-Na mhinduro. Kusachena kwakadai sesimbi ion uye chloride ions mumvura kunogona kuita kemikari neCMC-Na, zvichikanganisa kugadzikana uye kuita kwemhinduro.
3. Disolution nzira uye matanho
Kuparara kweCMC-Na idanho rinononoka, rinowanzoda kuitwa mumatanho:
Pre-wetting: Usati wawedzera CMC-Na powder kumvura, inokurudzirwa kuti isati yanyorovesa nekashoma ethanol, propylene glycol kana glycerol. Izvi zvinobatsira kudzivirira hupfu kubva mukusangana panguva yekuparara uye kugadzira mhinduro isina kuenzana.
Kudya zvishoma nezvishoma: Zvishoma nezvishoma wedzera CMC-Na poda pasi pemamiriro ezvinhu anokurudzira. Edza kudzivisa kuwedzera huwandu hwehupfu panguva imwe chete kuti udzivise kuumbwa kwemapundu uye kuoma kwekuparara.
Kukurunga zvizere: Mushure mekuwedzera hupfu, rambai muchikurunga kusvika hwanyungudika zvachose. Iyo yekumhanyisa kumhanya haifanirwe kunge ichimhanya zvakanyanya kudzivirira chizvarwa cheakawanda mabhuru uye kukanganisa kujeka kwemhinduro.
Temperature control: Tembiricha panguva yekuparara ine imwe mhedzisiro payero yekuparara. Kazhinji kutaura, tembiricha iri pakati pe20°C ne60°C ndiyo yakakodzera. Kunyanya kupisa tembiricha kunogona kukonzera mhinduro viscosity kudzikira uye kutoparadza chimiro cheCMC-Na.
4. Kuchengetedza uye kugadzikana kwekugadzirisa
Iyo yakagadziriswa CMC-Na mhinduro inofanirwa kuchengetwa mumudziyo wakavharwa uye kudzivirira kusangana nemhepo kudzivirira kunyura uye oxidation. Panguva imwecheteyo, zuva rakananga uye nzvimbo yakakwirira yekushisa inofanira kudziviswa sezvinobvira kuchengetedza kugadzikana kwemhinduro. Munguva yekuchengetedza kwenguva refu, mhinduro inogona kuipa nekuda kwekukura kwehutachiona, saka iwe unogona kufunga nezvekuwedzera mishonga yakadai se sodium benzoate uye potassium sorbate paunenge uchigadzira.
5. Kushandisa uye kurapwa kwemhinduro
Paunenge uchishandisa CMC-Na mhinduro, unofanirwa kungwarira kuti usasangana neakasimba asidhi uye mabhesi akasimba kuti udzivise kuita kwemakemikari kunokanganisa kugadzikana uye kuita kwemhinduro. Uye zvakare, CMC-Na mhinduro inoshatirisa ganda nemeso kusvika padanho rakati, saka iwe unofanirwa kupfeka zvakakodzera zvekudzivirira paunenge uchiishandisa, senge magirovhosi, gogi, nezvimwe.
6. Kuchengetedzwa kwezvakatipoteredza uye kuraswa kwemarara
Paunenge uchishandisa CMC-Na, iwe unofanirwa kuterera kune kuchengetedzwa kwezvakatipoteredza kwemarara. Tsvina CMC-Na mhinduro inofanirwa kubatwa zvinoenderana nemirairo yakakodzera kudzivirira kusvibiswa kune nharaunda. Marara anogona kazhinji kurapwa ne biodegradation kana makemikari kurapwa.
Paunenge uchigadzira sodium carboxymethyl cellulose mhinduro, zvinodikanwa kunyatso funga uye kushanda kubva kune akawanda maficha senge mbishi kusarudzwa, nzira yekunyungudika, mamiriro ekuchengetedza uye kuchengetedzwa kwezvakatipoteredza kurapwa. Chete pasi pechigadziro chekutonga kwakasimba kwechibatanidza chega chega chinogona kugadzirisa mhinduro kuve nekuita kwakanaka uye kugadzikana kuzadzisa zvinodikanwa zveminda dzakasiyana dzekushandisa.
