Design and Optimization of Cold Water Cleaning Agent Formulations
Cold water removal and degreasing can reduce the waiting time for the cleaning solution to heat up,improve production efficiency,and reduce steam and energy consumption,which benefits environmental protection and supports sustainable economic development.In order to screen the raw materials suitable for cold water oil removal,the contact angle was used as an index to characterize their hydrophilicity,and the cleaning effects of various surfactants,washing aids and solvents on animal,vegetable and mineral oils at low temperature were tested.TEXZO-PAS80,phosphorus free detergent EDDHA-Na and ethylene glycol monobutyl ether,which were found to have a cleaning effect on animal,vegetable and mineral oils,were determined to be the raw materials for cold water oil removal and degreasing.The experimental results showed that the optimal amounts of TEXZO-PAS80,EDDHA-Na and diethylene glycol monobutyl ether for cleaning mixed oil stains under cold water conditions at 10 ℃ were 3,3,and 2 g/L,respectively.
