Process for the inhibition of the formation of deposits in cellulose pulping and cellulose pulp treating processes |
摘要 |
A process is provided for inhibiting the formation of deposits in the course of pulping lignocellulosic material and in the treating of cellulose pulp, by addition to the cellulose pulping or treating process of compounds of polyvalent metals other than aluminum and manganese capable of complexing deposit-forming anions, thereby maintaining the deposit-forming anions in solution in the form of a liquor-soluble complex.
