摘要
本文介绍了在试验条件下,烧碱法麦草浆黑液的比重,固形物含量以及温度三者之间的关系,黑液粘度、固形物含量及温度三者之间的关系。试验了添加含钠化合物对黑液粘度、发热量的影响。试验结果表明,含钠化合物对黑液粘度的影响作用排列如下: Na_2S>Na_2SO_3>Na_2SO_4>NaOH>NaCl>
Black liquor from wheat straw soda process have been studied over the physico-chemical characteristics. The relation of density, solid content and temperature of soda wheat straw black liquor can be expressed as following general equation;D (g/1) =1.0074-0. 00461 + 0. 0060S The viscosity-temperature relation was presented for liquor from laboratory cook. The empirical formula;NT = 0. 0028S(3.34-0.01) R=0. 91gives the relationship among viscosity, temperature and solid content of black liquor.The effect of addition of NaCl, Na2CO3, Na2S, Na2SO3, Na2SO4 to the wheat straw liquor from soda process were stud icd. The effect of sodium composition on viscosity of black liquor was arranged its order from high to low as follows;Na2S>Na2SO3>Na2SO4>NaOH>NaCl>Na2CO3
