FOCUSED BEAM REFLECTANCE MEASUREMENT

Introduction:
This introduction presents several uses of focused beam reflectance measurement (FBRM) as tool to measure flocculation. It includes information on the interaction of wet-end aids with the different pulp fractions, such as optimal polymer dosage and the resulting floc properties (floc size, strength, etc.) and all the filler in the process both making Fiber Cement Sheet and Paper Sheet.

Background :

Flocculation is a complex phenomenon that is extremely important in both Fiber Cement Sheet and Paper Sheet process.
The flocculation is intermediate state between the raw materials and the final product in both Fiber cement and Paper Manufacture.

Functions of FBRM for Engineers/ scientists or operator :

- Identification of flocculation mechanism a real time in process
- Monitoring and control to deflocculation and reflocculation in the process
- Identify dissolved and colloidal material agglomeration of mixture material .
All the functions to enable the engineers, scientists or operator with all the information to enhance process performance and easy to handle or prepared particles to the next process.

Why , used a FBRM
- Can monitoring the particle size or floc size
- Can see all the process of Deflocculation and Reflocculation
- Can make / evaluation thru the picture (photo) time to time process

Added technology to Engineers/ Scientists or Operator:

- Real time to control the process i.e additive , filler, pulp, cement etc.
- Achievement to standardization of finish product.etc
