電化學分析儀器在鹼法製漿控制上之應用

The Applications of Electrochemical Instruments on the Control of the Alkaline Pulping

摘要


本研究係探討利用常見之電化學分析儀器迅速測定鹼法製漿廢液中殘留之鹼含量,以間接推翻紙漿蒸煮情形,達成線上控制之目的。以pH計測定製漿廢液及其稀釋液之pH值與電位差;或以電導儀測定紙漿廢液之導電度,均可藉由測定值相當準確推測組漿之總得率、卡巴值、木質素含量及黏度,其中尤以電導儀為最佳,其決定係數大部分均高於0.90。

The purpose of this study is to estimate the properties of pulp from testing the residual alkaline of cooking waste by electrochemical instruments. The pH meter was used to measure the pH value and the potential difference from cooking waste and its dilution. The conductivity of cooking waste was tested by conductrometer. The total yield, kappa number, lignin content, and viscosity of pulps can be evaluated as measuring the conductivity of cooking waste with conductrometer. Most of the coefficients of determination from conductrometer are above 0.90.
