Application of organosilicon defoamer in industrial production process

1.

• Compared with other organic defoamers, the effective dose ratio is greatly reduced, thus significantly reducing the use cost (50 PPM effective)

• Compared with other organic defoamers, the durability is often much longer (more durable)

• Often less reactive in the foaming medium, thereby reducing compatibility issues

• Stable in a wide range of temperature and pH

  
  

2.

In view of the different application environment requirements of defoamers, silicone defoamers mainly include the following types:

• Fluid type: inert, low-toxic silicone oil, wide viscosity range, defoamer in non-aqueous systems

• Dispersion type: aliphatic solvent dispersion, mainly used for applications in oil and natural gas production processes

• Compound: 100% active ingredient-oily, hydrophobic silica powder to improve defoaming efficiency, mainly used in non-aqueous systems

• Emulsion: defoamer compound emulsified in water, suitable for controlling foam in aqueous system applications

• Concentrate: high-concentration polyether modified self-emulsifying product

• Powder: solid powder compound defoamer, which can be added to dry products to prevent foaming when adding liquid, such as adding to washing powder

Some knowledge about the application of silicone defoamers

In the process of selecting a defoamer, it is first necessary to understand the foaming liquid, the detailed cause of foaming, temperature, PH value and other related information and the requirements for defoaming, in order to better choose the defoamer to solve the problem

• The defoaming and anti-foaming effect of defoamers is generally proportional to the amount, but there is also a saturation point, that is, after reaching a certain concentration, adding the amount again cannot prolong the anti-foaming time

  
  

• The defoaming and anti-foaming effect of defoamer is gradually weakened and disappeared over time

  
  

• There is no relationship between the viscosity and concentration of the defoamer

  
  

• It is meaningless to compare the concentration of different types of defoamers from different manufacturers
