用透光率变化率的经时变化，在准三组分相图全组成范围内研究了黑液体系的配伍性。同时用黑液体系使用性质的经时变化，研究了黑液体系中２３配方的配伍性。研究结果表明，在绝大部分组成区域内，黑液体系中的各种成分间是配伍的。黑液体系的使用性质随时间变化，其原因是由黑液体系中各种成分自身性质决定的，且主要是由于黑液的不稳定性造成的。黑液可用稳定剂来稳定。就２３配方而言，各种成分间是配伍的。
The compatibility of black liquor system was studied in the whole composition of the quasi-three-component phase diagram with the change of the rate of change of transmittance. At the same time, the black-liquid system was used to study the compatibility of 2 to 3 formulations in black liquor system over time. The results show that the composition of the black liquor system is compatible among most components. The nature of use of the black liquor system changes over time due to the nature of the various components of the black liquor system and is mainly due to the instability of the black liquor. Black liquor can be used to stabilize stabilizers. In terms of 2 3 formula, the various components are compatible.
