FOAM CONTROL IN THE FIBER CEMENT MACHINE

FOAM
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..  .

RETENTION AND DRAINAGE MECHANISMS

How to Making the Good Product of Fiber Cement Board ???

Have a 3 ways or tips,

1. Chemicals/Additives program

2. Man Power- Knowledge and SOP

3. Equipment - Knowledge 

One of the important think to Making Fiber cement Board , Chemicals/ Additives is i.e

Polyelectrolite

the Function as ;

Coagulation - Coagulation is the reduction of the repellant forces between particles such that they no longer repel one another.

Flocculation - Flocculation is combining or forming a “bridge” between the neutralized particles to produce discrete agglomerates.

Filtration - Filtration is the trapping of the agglomerated particles in the forming sheet.

Why needed Polyelectrolite ???

Many an anionic and cationic material in the system of material processing to making Fiber Cement Board. The sources will come from

- Fibres and Fines

- Residual Unbleaching Pulp ; Dissolved lignin, pitch and hemicellulose

- Additives; Contaminants cycle up in the process making the pulp especially with increased 

                   the closed loop process.

- Filler / Binder : Powder silica, Cement or others

Material of Polyelectrolite - FLOREN 1669, or FLOREN series

Quality of Fiber Cement !

QUALITY !!?

How to achive the better or good products of Fiber Cement Board and Roofing ?
All of Manufactures want to achives the good results at the end of their processes,
The Formula are
                                                                       M O C + S

M is Mechanical , Machine type of Fiber Cement Board and Roofing .
     Choising the right machine of Production Line both of Fiber Cement Board or Roofing
     Make all think of your machine and supporting in good conditions, works well .
     Maintenace in tight scheduling and countinuing
     etc                                                                                
O is Operational of the machine,
     Parameters of the Machine i.e
     Hydroulic Pressure
     Vaccum
     Power Kwh or Ampers
     Temperatures
     Speed  etc
C is Composition of Material , Chemicals or additives
    Incorrect raw material composition
    Incorrect Chemicals or Additives dosage
    Incorrect Reaction Condition
    Improper Point of addition of Chemicals or Additives
    Poor of Composition or Chemicals / Additives programs etc.
S is Skill
   Skill how to make or processing the green sheet
   How to create and development the products, etc
