The powdery polyphosphate ferric sulfate was prepared from iron vitriol, the byproduct in titaniumpigment production by sulfuric acid process, and complex oxidant.
This paper investigated the film solidify system of two kinds of silicone, then dealt with the property test of silicone rubber ink by mixing with titaniumpigment solvent and other auxiliary.
We have accomplished directions for producing chemicals of white epoxy pad-transfer printing ink on this base, mixing with titaniumpigment, solvent, plasticizer and other auxiliary materials.
