Penentuan Viskositas pada Proses Pemutihan Pulp (Bleaching) di PT Toba Pulp Lestari, Tbk Sosor Ladang Porsea

Abstract

The quality of pulp produced at process of sulphate pulp (kraft) may be influenced by several factors, one of them is viscosity. The purpose of viscocity analysis is to know the power of pulp after bleaching. Based on result of analysis, it shows that viscosity of pulp sulphate (kraft) has that viscosity the standart of PT.Toba Pulp Lestari,Tbk Sosor Ladang Porsea is that for A4 paper is 16-18 and for A2 paper is 11-14. Based on data is result analysis, viscosity for A4 paper is 15,7-16,4 and for A2 paper is 12,9-14,1.
