Malaysia Application of ink defoamer Agent in Sand Washing Wastewater Treatment(1)





Polyether polyester modified organosiloxane
An organic polysiloxane with a comb like structure. N+m is about 50-250, and the molecular weight is controlled between 1000-150000. Its compatibility is adjusted by polyethers and polyesters, and the longer the chain, the better the phase compatibility. Polyether modifications are the most common in this category, typically using ethylene oxide and propylene oxide. With the increase of the content of ethoxy groups, their compatibility with water also improves, so it is also possible to synthesize water-soluble siloxane type leveling agents. Ethylene oxide and propylene oxide can be used alone or mixed to control hydrophilicity and lipophilicity. If both ethoxy and propoxy groups are contained, a silicone based leveling agent for both water and oil use is prepared,


Malaysia When general sand washing plants are carrying out sewage treatment, they should start to add chemicals to assist after the completion of sediment separation, fine sand extraction and other work. However, the complex composition of such chemicals combined with the influence of external factors will produce foam in sand washing wastewater treatment, which will bring only disadvantages but no benefits. For the treatment of sediment and sand washing wastewater, the sand washing wastewater treatment defoamer can not be more appropriate to eliminate the foam problem. It is targeted at the foaming mechanism and link system of the sand washing system. The finished products are mainly refined from organosilicon, polyether and other core components. Directly adding at the water inlet will not affect the separation and cleaning of sediment and other sediment,
