Temperatur dan Waktu (H-Faktor) terhadap Bilangan Kappa dan Viskositas pada Proses Pemasakan di Unit Digester PT.Toba Pulp Lestari,Tbk. Porsea

Abstract

One of the very important process in the pe -made pulp is wood chips cooking process. Where this process is said to be the early stages of the pulping process. The purpose of this cooking is for the separation of cellulose and hemicellulose from the lignin and extractive substances . In the cooking process in the digester unit there are a few things to note for good produce pulp that is temperature and time ( H – factor ) because it greatly affects the kappa number in the pulping process . The H - factor will destroy the strength of the pulp . And if this variable is too low then the resulting yield very little. In PT.Toba Pulp Lestari Tbk Porsea produced kappa good on the digester is 11-13, dan viskosity 11-12 Cp the temperature used is 165-170 , the H - factor is carried out between 2000-2200 . But this is also done depending on consumer demand , how viscosity ( strength ) pulp they ask for them to buy in PT.Toba Pulp Lestari Tbk Porsea .
