FREE AND INDEPENDENT – Time for change is NOW!
Good preparation, communication and cooperation between operators on the “wet” side of the Board-line is essential for success of the change. Some advanced planning and changes could prove to be the factor determining success or failure of the change.
Board weight changes dramatically from 8.1 kg/m2 for 1312RE board to 10.5 kg/m2 for 1312FR board. This represents change of approximately 40 kg/min to the Stucco set point. It is important to know that heavier board is harder to dry. Increase in board weight during this product change is achieved through slowing down Board-line and adding Fly-ash and Vermiculite to the mix. Reduction to Stucco set point during this change must FOLLOW reduction in Board-line speed to make sure that board weight is as required or HIGHER.
