Embodiment Construction
[0013] The defoamer described in this example is made of the following components: simethicone 60kg; glycerol polyether 305015kg; liquid paraffin 15kg, water 10kg.
[0014] The defoamer manufacturing process described in the present embodiment comprises the following steps:
[0015] Add 10kg of water into the reactor; slowly add 60kg of dimethyl silicone oil into the above reactor, start stirring at a speed of about 50 rpm, and stir at room temperature to form an emulsified solution; add 15kg of glycerol polyether 3050, Continue to stir at a speed of about 50 rpm until the glycerol polyether 3050 is completely dissolved in the emulsified solution; then add 15kg of liquid paraffin and continue stirring at room temperature at a speed of about 50 rpm until the liquid paraffin is completely dissolved in In an emulsified solution; stir slowly for 30 minutes, about 50 rpm, keep at 18°C-22°C, and react for 24 hours to prepare the defoamer of the present invention.
