Do you want high-quality mines? Try sodium hexametaphosphate

 Due to the increasingly scarce mineral resources, mineral mining increasingly uses lean and complex ore, so the amount of ore that needs to be processed is increasing. Beneficiation can improve the quality of mineral raw materials, reduce transportation costs, alleviate further processing difficulties, reduce processing costs, and realize the comprehensive utilization of mineral raw materials. Sodium hexametaphosphate is a commonly used regulator and inhibitor in mineral flotation.


The type and amount of flotation agent vary with the nature of the ore and the flotation conditions and process characteristics, and can also be changed according to the changes in the above-mentioned various conditions during the production practice.


The role of sodium hexametaphosphate in the regulator can be divided into five categories: (1) pH regulator (2) Activator (3) Inhibitors (4) Flocculant (5) Dispersant


Application in mineral processing and oilfield industry Sodium hexametaphosphate is commonly used in flotation, as well as carbonate minerals such as calcite and limestone. It is mainly used to suppress quartz and silicate minerals. The mineral processing mechanism of sodium hexametaphosphate is mainly:


Sodium hexametaphosphate can be used as an inhibitor in flotation operations to inhibit minerals containing these ions. It is an inhibitor of apatite, calcite, barite, carbonaceous shale and argillaceous gangue. This is because sodium hexametaphosphate can form complexes with Ca2+, Mg2+ and other multivalent metal ions. When flotation of pyrochlore containing niobium, tantalum, thorium and zirconium containing zirconium, sodium hexametaphosphate can be used to inhibit Gangue minerals such as feldspar, nepheline and kaolin.


In the flotation of albite, zircon nepheline, pyrochlore and kaolinite, sodium hexametaphosphate can reduce sodium oleate without selectivity according to the tracer atomic test, and can react with multivalent metal ions of mineral profile.

What role will industrial grade sodium hexametaphosphate manufacturers play in the future coating industry?

图片
The keyword in 2019 is environmental protection and safety. In 2020, environmental protection and safety hurricanes will be more violent. In the manufacturing industry, whether it's packaging, printing, furniture, shipping industry or the phosphate raw material manufacturing enterprises like Chongqing Chuandong Chemical Group that produce  industrial grade sodium hexametaphosphate , it's a good choice to withstand the environmental storm and the obvious environmental protection conditions of the enterprise itself. Take the paint industry for example, the current paint market can be found that although the domestic paint industry has achieved rapid development and formed a certain industry scale, but in the domestic high-end paint market, the domestic paint brands or enterprises are indeed few, and the domestic high-end paint market is still occupied by most of the market share of imported brands. In fact, all industries need to use coatings, and environmental protection coating

What is the use of calcium formate industrial grade in construction? The manufacturer tells you

  With the development of the city's economy, the construction of highways, bridges, tunnels, and civil construction projects will require stricter use of early strength agents. Especially in winter, in order to improve the construction period, the cement mortar needs to be raised as soon as possible and put into use.   Calcium formate industrial grade   is a good early strength agent. Although both calcium formate and calcium chloride are calcium salts, relatively speaking, the performance of calcium formate is more stable. Because the formic acid in calcium formate is a weak acid. The solution will be weakly alkaline during the hydrolysis in the aqueous solution. It can be widely used in mortar. Calcium formate industrial grade is now a newly developed low temperature early strength accelerator in China, which has been widely used in various construction cement mortars. The earliest known and used chlorine salt early strength agent in construction, but the chloride salt early str

The effect of calcium supplement with feed grade calcium formate is good when crops are short of calcium

  Is it true that crops also need calcium supplements? it is true. Crops are plants, like humans and animals, that need rich trace elements to help them grow. When crops are calcium-deficient, plant growth is hindered, and the internodes are shorter, so they are generally shorter than normal plants and have soft tissues. Since calcium has such a big effect, is it good to use   feed grade calcium formate   to supplement calcium? The meristems such as the apical buds, lateral buds, and root tips of crops with calcium-deficient plants first appear nutrient deficiency, which is perishable, the young leaves are curled and deformed, and the leaf edges begin to turn yellow and become necrotic. For example, calcium deficiency can cause leaf scorch disease in cabbage, cabbage and lettuce; tomato, pepper, watermelon, etc. have heart rot; apples have bitter pox and water heart disease. No matter how much is useless, the crops are short of calcium. If we want to achieve the actual effect, what sho
