What are the properties of defoaming agents?

--Defoamer dispersibility in water: Under stirring, 90 g of process water was slowly added to a beaker containing 10 g of defoamer, and gently shaken to observe its dispersion in water (excellent: rapid diffusion; medium: most of the dispersion was slow, and a small amount of flocculent The material is more difficult to disperse; poor: not easy to disperse, and the floc is difficult to disappear, the cup wall has oil).

-- High temperature resistance (high temperature and high pressure cooking test). Take a certain amount of defoamer YAT722 in a beaker, dilute it evenly with about 4 times of water, and cook in a pressure cooker. When the temperature rises to 130 °C, start timing, cook at constant temperature and constant pressure for 2 hours, cool down to room temperature. The sample was taken out to observe the high temperature and high pressure resistance (130±2 ° C, 2 h) performance and the presence or absence of delamination and oil droplets drifting out.

--Shear resistance (high shear resistance test). 100 mL of the sample was taken, diluted with water to 500 mL with stirring, heated to 85 ° C and 95 ° C, respectively, and sheared at 3000 rpm for 1 hr under a high speed shearing machine to stop shearing, and the oily condition was observed.

--Electrolyte resistance, acid and alkali resistance, compatibility and viscosity, etc., can be contracted according to the actual application process and applicable environment of the customer.
