In the synthesis process, the selection of appropriate water quality is an important link. Although many people generally believe that synthesis only needs soft water, in fact, the impact of water quality is not determined by a single factor.
First of all, for the requirements of electrical conductivity, pure water is the best choice, and its electrical conductivity is the best within 20. Followed by soft water, if there is no pure water or soft water, tap water or natural water quality pen PPM within 200 is also available. However, it should be noted that with the increase of electrical conductivity, the speed and efficiency of the polymerization reaction will also increase, but the molecular weight of the product will be larger, which may lead to the product becoming sticky and the water reduction rate will be reduced.
Compared with tap water, well water, etc., softened water can largely ensure the stability of product performance. This is because the content of ions in the softening water is low, which has less influence on the polymerization reaction. Therefore, the use of softened water in the synthesis process can effectively control the performance of the product.
Especially for 6c mother liquor, the conductivity of water has a great influence on product performance. In general, water with a stable conductivity of about 100-150 works best. If the conductivity is too low, it may be necessary to increase the variety and number of catalysts to ensure the stability of the reaction. In addition, the addition of pure water to ferrous sulfate is also a feasible solution, which can ensure the stability of the reaction.
In summary, although soft water is a relatively good choice, we can also achieve stable product performance by reasonably controlling other water quality parameters during the synthesis process. The key is the flexibility to select the right water quality and catalyst solution according to the specific synthesis needs and environmental conditions to ensure the stable and reliable performance of the final product.
