Foam is one of type of colloidal system a gas dispersed in a liquid. The gas is nearly always air or carbon dioxide and the liquid is ussually water.
Foam can be observed in the bulk of the liquid or the surface as gas pocket or bubbles that are separated by thin liguid films.
FOR A LIQUID TO SUPPORT STABLE FOAM THERE ARE THREE COMPONENT MUST BE PRESENT :
1. A source of air or another gas
2. A source of mixing energy to disperse the gas in the liquid
3. Some foam stabilizing material at the gas or liquid interface.
THERE ARE THREE COMMON AND TROUBLESOME TYPES OF FOAM IN FC or FCB SYSTEM
1. Surface foam
2. Entrained air
3. Static foam
HOW TO CONTROL THE FOAM
1. Mechanical control
2. Chemical or additive control with foam control agents.
MAK Products Series i.e as Foam control agent was very effective to using in the process making of Fiber Cement.
MAK Series is a blend mineral and organic compound copolymer is very effective an antifoam or defoamer.
The presence of foam in the process can have several detrimental consequences on daily operations.
In the fiber cement process were feeding to back water return as Defoamer and to distributor chest or level box before to the vats cylender as Antifoam.
Application of Gofoam Series.
Within 50 -150 ppm max will cover and protected the foam problem in the process
Many of Fiber Cement and Fiber Cement Board manufacture in Indonesia have using a MAK Defoamer or Antifoam.. .
