The deposition of resin in pulp will have a great impact on papermaking, of which two are the most important: the first is that the deposition of resin can lead to the decline of product quality, and the second is that the deposition of resin will affect some later paper manufacturing processes and reduce the output of products.Resin in Pulp and Its Harm.
In the paper making stage, the resin is easy to deposit in the blanket and water suction tank, and also on the screen plate, headbox, papermaking net, couch roll, press roll and calendering roll of drying cylinder. Resin in Pulp and Its Harm
These precipitates can directly affect the dehydration efficiency and the uniformity and strength of the paper, resulting in some spots and small holes in the paper, so as to reduce the quality of the finished product.Resin in Pulp and Its Harm
In the three stages of pulp washing and bleaching, the resin in the pulp will be deposited on the sieve plate, thickener, inner wall of pipeline, surface of pulp tank, screw of pulper, etc. More seriously, these sediments may fall off from the surface and block the screen plate and slag remover, thus greatly reducing the screening and purification efficiency.Resin in Pulp and Its Harm

The content of resin in pulp can reduce the adhesion between fibers, reduce the strength of pulp, and affect the water absorption of pulp, especially fluff pulp.Resin in Pulp and Its Harm
