CMC imagwiritsa ntchito mu Detergent Viwanda

Carboxymethyl cellulose (yomwe imadziwikanso kuti CMC ndi sodium carboxymethyl cellulose) imatha kufotokozedwa ngati polima yosungunuka m'madzi ya anionic, yopangidwa kuchokera ku cellulose yachilengedwe kudzera mu etherification, m'malo mwa gulu la hydroxyl ndi gulu la carboxymethyl pa cellulose Chain carboxymethyl cellulose imagwiritsidwa ntchito ngati binder, thickener, suspending wothandizira ndi filler zosiyanasiyana ntchito.

Mfundo yochitira

Zomwe zimachitika kwambiri pamankhwala a CMC ndi momwe ma cellulose amachitira ndi alkali kupanga alkali cellulose ndi etherification ya alkali cellulose ndi monochloroacetic acid.

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

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

Chemical chilengedwe

Chochokera ku cellulose chokhala ndi carboxymethyl substituent chimakonzedwa pochiza mapadi ndi sodium hydroxide kupanga alkali cellulose, kenako ndikuchita ndi monochloroacetic acid. Glucose unit yomwe imapanga cellulose ili ndi magulu atatu a hydroxyl omwe amatha kusinthidwa, kotero kuti zogulitsa zokhala ndi magawo osiyanasiyana zitha kupezeka. Pafupifupi, 1mmol ya carboxymethyl imayambitsidwa pa 1g ya kulemera kowuma. Sipasungunuke m'madzi ndi kusungunula asidi, koma imatha kutupa ndikugwiritsidwa ntchito posinthanitsa ndi chromatography ya ion. PKa ya carboxymethyl ndi pafupifupi 4 m'madzi oyera ndi pafupifupi 3.5 mu 0.5mol/L NaCl. Ndiwosintha pang'ono acidic cation exchanger ndipo nthawi zambiri amagwiritsidwa ntchito polekanitsa ma protein osalowerera komanso ofunikira pa pH 4 kapena kupitilira apo. Omwe ali ndi magulu opitilira 40% a magulu a hydroxyl osinthidwa ndi carboxymethyl amatha kusungunuka m'madzi kuti apange njira yokhazikika ya colloidal high-viscosity.

Mankhwala makhalidwe achotsukira Mtengo wa CMC

Pambuyo powonjezeredwa ku chotsukira, kusinthasintha kumakhala kokwera, koonekera, ndipo sikubwerera kuonda;

Iwo akhoza bwino thicken ndi kukhazikika zikuchokera madzi detergent;

Kuonjezera ufa wochapira ndi detergent wamadzimadzi kumatha kuletsa dothi lomwe latsuka kuti lisakhazikikenso pansalu. Kuwonjezera 0.5-2% ku zotsukira zopangira zimatha kupeza zotsatira zogwira mtima;

CMC imagwiritsa ntchito mu Detergent Viwanda, MakamakaOnani kwambiri pa emulsification ndi chitetezo colloid katundu CMC. Anion opangidwa panthawi yotsuka amatha kupanga nthawi imodzi pamwamba pa kutsuka ndi dothi particles zoipa, kotero kuti dothi particles kukhala ndi gawo kulekana mu gawo madzi ndi zotsatira zofanana pamwamba pa olimba kusamba. Kuthamangitsa, kumalepheretsa dothi kuyikanso pa zovala, kumatha kusunga zoyera za nsalu zoyera, ndi mitundu yowala ya nsalu zamitundu.

Ntchito CMC muchotsukira

1. Kukhuthala, kubalalitsa ndi emulsifying, kumatha kuyamwa madontho amafuta kuzungulira mawanga kuti akulunga madontho amafuta, kotero kuti madontho amafuta atayimitsidwa ndikubalalika m'madzi, ndikupanga filimu ya hydrophilic pamwamba pa zinthu zotsuka, potero amalepheretsa madontho opaka mafuta polumikizana mwachindunji ndi zinthu zotsuka.
2. Mkulu digiri ya m'malo ndi chimodzimodzi, bwino poyera;
3. Dispersibility yabwino m'madzi ndi kukana kwabwino kwa resorption;
4. Super kukhuthala kwapamwamba komanso kukhazikika kwabwino.
