Abstract
Deposit is a difficult issue to deal with in the paper making process. One of the solutions for deposit is chemical treatment which has two different addition methods, surface treatment and internal treatment. Surface treatment is to spray the chemical in only contaminated place, e. g. wire or felt, to deal with the problem at there. Disperser or sticky control is one of the chemicals of internal treatment which can control any deposit throughout the process. Overall deposit control can be achieved by combination of above treatments.
I explain sticky pitch issues mainly in this article.
