MASTER plastic rattan molding immersion filtration to remove the influence of impurities on the gypsum mold performance
The use of desulfurization gypsum produced die cast, there are raw material composition and processing process, desulfurization gypsum produced will contain a variety of impurities, these impurities including fly ash, calcium carbonate, calcium sulfate, organic calcium and sodium, potassium, magnesium sulfate or chloride composition of soluble salt. In addition to these, there is also a caseof nature when limestone adverse or grain position unreasonable, the desulfurization gypsum impurities out of production, quality and use of gypsum will cause great influence. One of the biggest impurities harmful to the flue gas desulfurization gypsum is mainly by chloride MASTER plastic mold manufacturer dominated the soluble magnesium salt and sodium salt, they on the plaster mold bonding properties, rheological properties significantly. In a humid environment will make gypsum produced "return frost" phenomenon, the quality will seriously affect the plaster mold such conditions. Also in the production process, because the pulverized coal combustion efficiency is low and the dust removal efficiency is not normal, the fly ash settling down in the desulfurization gypsum slurry in flue gas, thus affecting the bond strength and color appearance later plaster mold and gypsum mold. In order to reduce theinfluence of impurities of soluble salts, such as fly ash on the performance of desulfurization gypsum, we take a series of measures, in the heating dehydration before the water soaked filter are pre processing. After processing, the desulfurization gypsum can normal setting. The main components of desulfurization MASTER plastic container moldinggypsum and natural gypsum is basically the same, but because of raw material, process is different, resulting in the gypsum particle morphology, crystal, impurity so different, affects the performance of the plaster mold. In order to realize the comprehensive utilization of desulfurization gypsum better, must be carried out according to the characteristics of FGD gypsum itself. Particle size distribution of poor desulfurization gypsum, will have a negative effect on the performance of gypsum slurry, can take the "ground" measures, to improve the particle size distribution of the desulphurization gypsum and natural gypsum mixed use.
