Carboxymethyl cellulose (cmc) yog ib txwm siv flotation nyuaj siab {}} Cov lus qhia ntawm Talc thiab Pentlandite.
1. talc
Cov teeb meem carisce ntawm carboxymethyl cellulose (CMC) ntawm cov khoom siv TALC thiab cov kev hloov pauv ntawm Talc maj mam nce, uas qhia tau tias Kev Desorption yog qeeb. tib lub sijhawm ua haujlwm hauv Talc} Nws tuaj yeem hloov ua cov lus qhuab qhia ntawm Hydrophobic Tsevneeg thiab Hydrogen bonding .} Qee cov kws tshawb fawb ntawm CMC reacts ntawm cations ntawm cov zaub mov thiab cov polymers {6.
CMC muaj peev xwm txhim kho cov wettable ntawm talc particle txheej ntawm sulc me ntsis kev sib cais ntawm salc me me los xij, yog li ua kom lub suab nrov sib cais vim tias ua npuas ncauj .
CMC can enhance the negative charge of the talc surface and make the talc more dispersed in water, but this is not beneficial to its inhibition of talc. On the contrary, the aggregation between particles that can cause the surface area to decrease is conducive to the inhibition of talc.
CMC yog Adsorbed ntawm txheej thiab kawg saum npoo ntawm talc los ntawm ob pab pawg ntawm cov pab pawg ntawm hydroxyl thiab carboxyl thiab carboxyl pawg {}}
Cov inisitions cov nyhuv ntawm Talc kuj muaj feem cuam tshuam nrog kev daws teeb meem molc, tab sis kuj cuam tshuam lub zog ntawm kev them nqi ntawm CMC; Tsawg PH nqi thiab high hlau ion concentration yog qhov tseem ceeb los txhawb kom txhawb nqa qhov inhibition ntawm CMC ntawm Talc ntawm Talc ntawm Talc.
2. pentlandite
CMC muaj ob pawg muaj zog polar, namely -h thiab -cooh.}} Yog li ntawd, cmc yog adsorbed nyob rau saum npoo ntawm Serpentine los ntawm electrostatic adsoratic. lub tsev ntawm Serpentine los ntxiv, CMC tuaj yeem siv cov duab dej nrog cov hlau ions rau saum npoo ntawm serpentine, yog li inhibiting serpentine los yog av nkos .
