What are the uses of electronic grade hydrochloric acid? The manufacturer tells you

 Electronic grade hydrochloric acid has a wide range of applications in various fields of our lives, such as medicine, chemical industry, semiconductor, large-scale integrated circuit and other industries. Electronic grade hydrochloric acid is mainly used for high temperature gas phase etching of silicon and arsenic before epitaxial growth to clean sodium ions. In addition, high-purity hydrochloric acid is also used in metal surface chemical treatment, mixed gas for laser, film production and carbon fiber surface treatment.


At present, most of my country's high-purity electronic grade chemicals rely on imports. With the rapid development of the domestic electronics industry towards high integration, high uniformity and high integrity, the requirements for electronic grade hydrochloric acid, which is widely used in the vapor phase polishing of monocrystalline silicon and the corrosion of epitaxial frames, are becoming higher and higher.


Status of domestic hydrochloric acid market:

1. Most domestic hydrochloric acid companies set prices according to the market, and determine the output according to the market. The market supply is sufficient and the operating rate is unstable;

2. The market of synthetic hydrochloric acid is greatly affected by the market of upstream liquid chlorine, which rises and rises, and falls and falls;

3. It is difficult to balance chlor-alkali. At present, domestic chlor-alkali enterprises are in a state of adjustment and are transforming to the development model of chlor-alkali supplementation. The price adjustment of chlor-alkali products is an inevitable phenomenon;

4. The selling price of electronic grade hydrochloric acid is high, and most of them rely on imports.


With the rapid development of the national photovoltaic industry and new energy, the demand for electronic grade hydrochloric acid is increasing. In the past, my country mostly relied on imports, and in recent years many technological breakthroughs have been made. Electronic grade hydrochloric acid products have high added value and rich profits. They are fine chemicals with high technical content.


At present, only a few manufacturers produce electronic grade hydrochloric acid. The electronic grade hydrochloric acid produced by Chongqing Chuandong Chemical Group has a purity of over 99.999%. The content of organic impurities such as HCl, H20 and metal ions in hydrochloric acid is also required to be lower and lower. With the development of photovoltaic and new energy and new industries, the demand for electronic grade hydrochloric acid will also continue to grow. It is believed that the hydrochloric acid industry will enter a structural adjustment period of eliminating outdated production capacity and expanding the electronic grade hydrochloric acid industry.

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
