We mainly studied the relation between deinking efficiency of different recovery pulps and their colloid-chemical behavior such as Zeta potential and surface tension. Technical conditions that affect the deinking pulp’s colloid chemical behavior are also analyzed here.展开更多

The results preliminarily showed that the dissolved lignin could re-adsorb to fiber surface by means of fiber classification technology and explained the questions found during the study. Some measures were taken to reduce the kappa number, the results had shown that there was obvious absorption in the ethanol pulping; lignin remained in the pulp could easily be dissolved and the pulp with lower kappa number could be obtained at a higher temperature; the kappa number could reduce by increasing washing time; it could enable dissolved lignin to separate out from the ethanol pulp and restrain the lignin absorption by blowing cooking liquid at high temperature.展开更多

Results show: Pretreatment of xylanase and laccase has better effect than of sole xylanase and sole laccase; Coordination can increase pulp brightness and bleachability, improve pulp filterability of water, lighten degree of effluent pollution in bleaching workshop, and develop overall strength properties of bleached pulp.展开更多

文摘The programming technology about Embedded SQL discuss the form of Embedded SQL base on C/C++ language and ORACLE9i DBMS in this paper. We have also discussed the communications between the sentence of Embedded SQL and C/C++ language and have provided the code.
文摘In this paper, the old newsprint and the common domestic old paper are subjected to deinking process. We mainly studied the relation between deinking efficiency of different recovery pulps and their colloid-chemical behavior such as Zeta potential and surface tension. Technical conditions that affect the deinking pulp’s colloid chemical behavior are also analyzed here.
