Reading: In 2017, domestic nitsu sulfate production volume will rise to 300,000 tons; foreign production volume will be approximately 200,000 tons. In addition to Sumitomo Group, Omegro and Omegro, several companies are also in the industry. Based on the subsequent expansion situation, global sulfate sulfate will rise to 600,000 RMB in 2018.
With the development of new power cars, new Sugar daddy‘s technology is constantly innovating, and many R&Ds have focused their attention on the information of new power batteries, aiming to seek new breakthroughs. As an important raw material in the battery field, Polysulfate has shown new demand growth, which has caused earth-shaking changes in the entire industry.
1. Growth of new demand for ozone: Overview of important raw materials for ozone sulfate in the battery field
1.1 Properties of ozone sulfate
Ozone sulfate, chemical formula is NiSO4, there are three types: unhydrate, hexahydrate (NiSO4˙6H2O), and heptahydrate (NiSO4˙7H2Sugar babyO), and their density is 3.68, 2.07, and 1.948g/cm3 respectively. Oxygen sulfate Escort manila mostly products are hexahydrates, with a molecular weight of 262Pinay escort.84, that is, the price of Oxygen sulfate refers to hexahydrates. There are two crystal structures: α- (tetragonal crystal, blue) and β- (singular oblique crystal, green).
Escort manila1.5℃ ozone sulfate solution crystal is heptidylhydrate. Ozone sulfate heptidylhydrate is a green bright crystal with a sweet smell and a slight windy nature. Crystalline at 31.5~53.3℃ is α-type hexahydric sulfuric acidSugar daddy电子 (blue-not clear crystal); 53.3℃ turns to be β-type, and at 103℃, it falls to 5 molecules of crystal water and becomes a water substance, and at 280℃, it falls to Escort All the crystal water of manila becomes a yellow-green, unwatery substance. It is differentiated into sulfur trioxide and ozoxide at 840°C.
The three kinds of ozone sulfate are easily soluble in water, and the aqueous solution is weakly acidic (pH 4.5). The waterless substance is insoluble in ethanol, ether, and acetone; hexahydrate is easily soluble in ethanol and ammonia water; hexahydrate is soluble in alcohol. Ozone sulfate is toxic and carcinogenic, and the highest allowable in airSugar daddy. Baby degree is 0.5mg/m3.
1.Sugar daddy2 preparation method for sulphate
The preparation method for sulphate2: There are five ways to prepare sulphate: (1) Metal oyster is dissolved in sulfuric acid. After crystallization, crude oyster sulfate crystals are obtained, and the crystals are then Sugar baby baby ablation, and after decompression, it obtains battery-grade ozone sulfate crystals; (2) In copper electrolysis, the metal pores are oxidized in the yang and ablated into pores sulfate. After decompression, it obtains battery-grade ozone sulfate crystals; (3) Pinay escortNonite minerals are processed into high ice oysters or oxidized oysters, oyster oxides, carbonate and other pill intermediate products, and then ablated into the sulfate concentration and crystallization, and then obtained sulfate hexahydrate. Important domestic sulfate sulfate enterprises’ financial resourcesSugar daddyChuan Pot Salt, Geen Pot Salt, Guangxi Silver Bill, etc. all produce sulfate sulfate through this method; (4) Preparation of ozone-containing solution during the production of metal sulfate href=”https://philippines-sugar.net/”>Sugar daddy preparation income; (5) including waste material preparation income, domestic representative enterprises and participants—Answered the question, and then made a statement about their answers including Greenmei, Chizhou Sean, Bangpu Xun, etc.
Today, Canada, South Korea, japan (Japan) and Taiwan use metal ozone to make pills sulfuric acid in the form of sulfuric acid. This preparation method has the advantages of high raw material purity, fewer quality, stable source, good quality of sulfate obtained from preparation, and small purification of the preparation process. The disadvantage is that the preparation cost is relatively high.
Our sulfate production in my country is mainly made of intermediate products, including complex sterilized ozone contained in copper electrolysis; sterilized ozone solutions in sterilized production; sterilized ozone oxide, sterilized ozone oxide and sterilized carbonate, etc. In fact, Chen Jubai and Sugar daddy does not quite meet the standards of Song Weipeng. The product in the middle of the ozone is made of dissolved in sulfuric acid; it is also used by the receiving pipe of the ozone-containing waste material. The important advantage is that there are many sources of raw materials and the production cost is low; the disadvantage is that the production process is more refined. With the country’s environmental protection layer code for industrial production, Sugar daddy‘s domestic sulfuric acid enterprises are facing a trend of turning to the transformation of metal oysters as raw materials.
2. The purpose of the high-price three-yuan tag is clear, and future demand may usher in an explosionManila escort
2.Sugar babyEscort1 Important uses of ozone sulfate: battery-level and oxidized grade
Ozone sulfate is divided into battery-level ozone sulfate (Ni quality fraction ≥22%, Co quality fraction 0.4%) and oxidized grade ozone sulfate (Ni quality fraction ≥21%, coarse quality fraction ≤0.05%) according to the purity of ozone and oxidized grade,It is also used in the battery and battery fields respectively. Electro-grade ozone sulfate is mainly used for the production of car wheels, appearance and other products.
In the battery industry, pill sulfate is mainly used in the traditional pill battery, pill slurry battery and the mainstream ternary electrostatic battery. Among them, the former oxidation battery has been gradually reduced due to memory effect and environmental protection during the charging process; the pill elements in the important raw material of the oxidation battery (spherical hydrogen oxide) and the front-drive raw materials of the ternary steel ionic battery ionic battery (NCM) or oxidation alumina acid (NCA) are all supplied by pill sulfate. Escort The important effect of the oximeter is to improve the energy density of the data and determine the battery capacity.
