Iwo makuru maratidziro ekuyera kunaka kweCMC ndiwo dhigirii rekutsiva (DS) uye kuchena. Kazhinji, zvinhu zveCMC zvakasiyana kana DS yakasiyana; iyo yakakwirira dhigirii yekutsiva, zviri nani kunyungudika, uye zviri nani kuve pachena uye kugadzikana kwemhinduro. Sekureva kwemishumo, kujeka kweCMC kuri nani kana dhigirii rekutsiva iri 0.7-1.2, uye viscosity yemushonga wayo wemvura ndiyo yakakura kana iyo pH kukosha iri 6-9.
Kuti ive nechokwadi chehunhu hwayo, mukuwedzera kune kusarudzwa kweiyo etherifying mumiriri, zvimwe zvinhu zvinokanganisa dhigirii rekutsiva uye kuchena zvinofanirwa kutariswa, senge dosage hukama pakati pealkali uye etherifying agent, etherification nguva, system mvura yemukati, tembiricha. , pH kukosha, kugadzirisa kugadzirisa uye munyu.
Sodium carboxymethyl cellulose inoshandiswa zvakanyanya mu petroleum, chikafu, mushonga, machira, papermaking uye mamwe maindasitiri, saka zvakakosha kuti utonge nemazvo kuchena kwayo, uye zvakare chiyero chekuvimbisa kushandiswa kwayo, saka, Tingaona sei, kunhuwidza, kubata, kana kunanzva kuti utonge kuchena kwayo?
1. Sodium carboxymethyl cellulose ine hutsanana hwepamusoro ine kuchengetedzwa kwemvura kwakanyanyisa, kufambiswa kwechiedza kwakanaka, uye mwero wayo wekuchengetedza mvura unosvika 97%.
2. Zvigadzirwa zvine kuchena kwepamusoro hazvizonhuhwi kunhuhwirira kweammonia, starch uye doro, asi kana zviri zvekuchena kwakadzika, zvinogona kunhuwa zvakasiyana-siyana.
3. Iyo yakachena sodium carboxymethyl cellulose inoputika inoratidzika, uye kuwanda kwehuwandu huduku, huwandu huri: 0.3-0.4 / ml; iyo fluidity yehupombwe iri nani, ruoko runonzwa runorema, uye pane musiyano mukuru nechitarisiko chepakutanga.
4. Kroridi yemukati yeCMC inowanzoverengerwa muCL, mushure mekunge CL yemukati yayerwa, NaCl yemukati inogona kushandurwa kuita CL%*1.65
Pane humwe hukama pakati peCMC yemukati uye chloride, asi kwete zvese, kune tsvina yakaita sesodium glycolate. Mushure mekuziva kuchena, iyo NaCl yemukati inogona kuverengerwa kuverengerwa NaCl% = (100-kuchena)/1.5
Cl%=(100-kuchena)/1.5/1.65
Nokudaro, rurimi-licking chigadzirwa chine simba rakasimba remunyu, zvichiratidza kuti kuchena hakuna kukwirira.
Panguva imwecheteyo, yakakwira-kuchena sodium carboxymethyl cellulose yakajairika fiber state, nepo yakaderera-kuchena zvigadzirwa zvine granular. Paunenge uchitenga chigadzirwa, unofanirwa kudzidza akati wandei nzira dzakapusa dzekuzivikanwa. Mukuwedzera, iwe unofanirwa kusarudza mugadziri ane mukurumbira wakanaka, kuitira kuti chigadzirwa chemhando chiwedzere kuvimbiswa.
