CMC inoshandisa muDetergent Industry

Carboxymethyl cellulose (inozivikanwawo seCMC uye sodium carboxymethyl cellulose) inogona kutsanangurwa seanionic mvura-soluble polymer, inogadzirwa kubva kune yakasikwa cellulose kuburikidza ne etherification, ichitsiva boka rehydroxyl neboka recarboxymethyl pa cellulose Chain carboxymethyl cellulose inoshandiswa sebinder, thickener, kumisa mumiririri uye filler mune akasiyana mafomu.

Reaction musimboti

Iwo makuru emakemikari maitiro eCMC ndeye alkalization reaction ye cellulose uye alkali kugadzira alkali cellulose uye etherification reaction yealkali cellulose uye monochloroacetic acid.

Danho 1: Alkalization: [C6H7O2(OH) 3]n + nNaOH→[C6H7O2(OH) 2ONa ] n + nH2O

Danho rechipiri: Etherification: [C6H7O2(OH) 2ONa ]n + nClCH2COONA→[C6H7O2(OH) 2OCH2COONA ] n + nNaCl

Chemical nature

Iyo cellulose inobva kune carboxymethyl substituent inogadzirwa nekurapa cellulose ne sodium hydroxide kugadzira alkali cellulose, uyezve kuita ne monochloroacetic acid. Iyo glucose unit inoumba cellulose ine 3 hydroxyl mapoka anogona kutsiviwa, saka zvigadzirwa zvine madhigirii akasiyana ekutsiva zvinogona kuwanikwa. Paavhareji, 1mmol yecarboxymethyl inounzwa pa1g yehuremu hwakaoma. Haina kunyungudika mumvura uye inoderedza asidhi, asi inogona kuzvimba uye kushandiswa ion exchange chromatography. Iyo pKa yecarboxymethyl inenge 4 mumvura yakachena uye inenge 3.5 mu 0.5mol/L NaCl. Iyo isina kusimba acidic cation exchanger uye inowanzo shandiswa kupatsanura mapuroteni asina kwaakarerekera papH 4 kana kupfuura. Avo vane anopfuura 40% emapoka e-hydroxyl anotsiviwa ne carboxymethyl anogona kunyungudutswa mumvura kuti aite yakagadzikana yakakwirira-viscosity colloidal solution.

Chigadzirwa maitiro edetergent giredhi CMC

Mushure mekuwedzera kune detergent, kuwirirana kwakakwirira, kwakajeka, uye hakudzokeri kuonda;

Inogona kunyatsoita gobvu uye kudzikamisa kuumbwa kwemvura detergent;

Kuwedzera washing powder uye liquid detergent kunogona kudzivirira tsvina inenge yagezwa kuti isagadzikane pajira zvakare. Kuwedzera 0.5-2% kune synthetic detergent inogona kuwana mhedzisiro inogutsa;

CMC inoshandisa muDetergent Indasitiri, Kunyanyafocus on iyo emulsification uye inodzivirira colloid zvimiro zveCMC. Iyo anion inogadzirwa panguva yekugezesa inogona kuita panguva imwe chete pamusoro pekugezesa uye zvimedu zvetsvina zvinopomerwa zvisina kunaka, kuitira kuti zvimedu zvetsvina zvive nekuparadzaniswa kwechikamu muchikamu chemvura uye zvive nemigumisiro yakafanana pamusoro pekushambidza kwakasimba. Repellency, inodzivirira tsvina kubva pakudzoreredza pakuwachira, inogona kuchengetedza kuchena kwemachira machena, uye mavara akajeka emachira ane mavara.

Function ye CMC mudetergent

1. Kuomesa, kuparadzira uye emulsifying, inogona kutora mavara ane mafuta kumativi ose kuti aputire mavara ane mafuta, kuitira kuti mavara ane mafuta amire uye akapararira mumvura, uye agadzire firimu re hydrophilic pamusoro pezvinhu zvakashambidzwa, nokudaro kudzivirira mafuta mavara kubva pakubata zvakananga zvinhu zvakagezwa .
2. Dhigirii yepamusoro yekutsiva uye kufanana, kujeka kwakanaka;
3. Yakanaka dispersibility mumvura uye yakanaka resorption kuramba;
4. Super high viscosity uye yakanaka kugadzikana.
