Flotation Potential ntawm Cardanol
Cardanol yog ib tug natural phenolic compound muab rho tawm los ntawm cashew txiv ntoo plhaub. Nws cov qauv molecular nta ib pawg hydrophilic hydroxyl thiab cov saw hlau ntev hydrophobic, ua rau nws yog amphiphilic molecule thiab muaj peev xwm sib tw rau cov ntxhia flotation. Cov kev sim qhia tau hais tias cardanol qhov kev sib sau ua tau zoo rau qee cov hlau oxides (xws li hematite) tuaj yeem ncav cuag 80% ntawm cov tshuaj reagents, thiab nws ua tau zoo nyob rau hauv pH ntau ntawm 6-8. Nws txheej txheej ua npuas ncauj kav ntev li 3-5 feeb, ua tau raws li cov kev cai yooj yim rau kev sib cais flotation.
Unique Mechanism of Action
Tsis zoo li ib txwm flotation agents, cardanol ua tiav cov ntxhia sib cais los ntawm triple mechanism:
Selective adsorption: Cov pab pawg phenolic hydroxyl tsim kev sib koom tes nrog cov hlau ions ntawm cov pob zeb hauv av.
Bubble regulation: Cov pa roj carbon ntev ntev hloov qhov nro ntawm cov npuas, tsim kom muaj txheej txheej ua npuas ntau ruaj khov.
Environmental degradation: Nws degrades ib txwm los ntawm 95% hauv 28 hnub, sai dua li petrochemical reagents.
Cov kev xav tau hauv kev siv
Txawm hais tias cardanol muaj qhov zoo ntawm biodegradability, tam sim no muaj peb qhov kev txwv tseem ceeb:
Kev sib sau ua haujlwm tau txo qis hauv qhov kub thiab txias (<15℃).
Nws nthuav tawm cov kev xaiv tsis zoo rau cov zaub mov silicate.
Loj - cov nqi rho tawm yog kwv yees li 30% siab dua li cov khoom siv hluavtaws.
