Abstract
The addition of sodium hexametaphosphate to the white water system of the paper mill is an effective method of preventing pitch deposition. The ability of this compound to prevent pitch agglomeration is due to its tendency of forming monomolecular films on metallic surfaces to which pitch will not adhere.
This thesis has attempted to evaluate whether this monomolecular protective film is best formed by spraying a solution of sodium hexametaphosphate onto the moving Fourdrinier wire or whether it is best formed by the present-day method of allowing the film to form from the white water system to which sodium hexametaphosphate has been added.
The results of my experimental work have indicated that no positive conclusion can yet be made regarding this question. However, there is a tendency for better film formation by spraying. Definite conclusions, however, can be made only by further experimentation.
