Silicone Defoamer can be divided into two categories: a class can eliminate the generated bubbles, such as ethanol, and the other can inhibit the formation of bubbles such as emulsified silicone oil. The defoamer used in China is emulsified silicone oil, high alcohols fatty acid ester complex, polyoxyethylene epoxy propylene pentaerythritol ether, polyoxyethylene polyoxyethylene ether, propylene glycol ether and propylene glycol polyoxyethylene, polyoxyethylene.
It is very easy to disperse in water and convenient to use. In a very wide range of ph and temperature has a fast defoaming effect and inhibition function, with all kinds of auxiliaries good compatibility, can quickly eliminate foam, and has the effect of preventing foam regeneration.
Physical and chemical data and indicators:
ph Value: 6.5-7.0.
Appearance: Milky white liquid.
Viscosity (25 ℃): 2500-3500cps.
Ionic properties: Non-ionic.
Application: This product is widely used in printing pulping, bleaching and dyeing, biotin fermentation, water-based additives processing, papermaking, pesticide, washing, adhesives manufacturing and other fields.
How to use it:
1, the CP-930 will be directly added to the foaming system to ensure its uniform dispersion.
2, the High foaming temperature system (>60℃), the proposed CP-930 in 60 ℃, before joining the system, dispersed evenly, to play its maximum effect.
3, according to different foaming system viscosity, temperature and stirring factors, to 10PPM units, choose the more economical dosage, generally speaking, 30-200ppm dosage can guarantee the ideal defoaming effect. But in some industries such as paints, bio-fermentation may be required by $number 0.
