organic cleaner
3."semi-aqueous cleaner" means a neutral or alkaline hard-surface cleaning formulation which combines the cleaning action of surfactants and organic solvents, including mineral spirits, glycols, glycol ethers, alcohols and terpenes, either emulsified in a water base; or in a concentrated form that can be rinsed in water.
4.The results show that the cleaner production of concrete polymeric concrete slump retaining agent is achieved by using multistage series reactions, water to replace organic solvent and complex initiator (K?2S?2O?8+30%H?2O?2) to replace toxic BPO in a still. It avoids the environmental pollution caused by the process for the production of traditional reactive polymer.
