PULP & PAPER  -  Pitch Control

Pitch control on paper and board machines has been a critical issue for a long time because it causes both quality and runa- bility problems.

In order to achieve an effective reduction of resins and stickies, they should be fixed on to fibers and fines in the smallest possible form before agglomeration of the particles begins.

It is usually achieved with organic and inorganic fixative products. For a successful fixation of colloidal material with minimized agglomeration, choice of product, dosage and dosing point are important variables.

When it comes to detecting, monitoring, and treating stickies, pitch, and white pitch deposits, we can support you with a specially developed analysis method ACAT Pitch Counter (APC). Download more information here.

In order to reduce pitch, we use different types of fixative products as bentonite, polyamine and polyDADMAC.
