Disinfecting water: 1.7 grams of calcium hypochlorite is dissolved in 1000 liters of water, forming 1/10000 disinfection water. Calcium hypochlorite is widely used as algaecide, bactericide, disinfectant, bleaching agent or chlorinating agent because of the effective chlorine component of the product. For example, it can be used for sterilization and disinfection in swimming pools, drinking water, cooling towers, mineral processing, sewage, food, agriculture, aquaculture, hospitals, schools, stations, homes and other fields, and it can also be used as an excellent bleaching agent and oxidant in paper making and printing and dyeing industries. Calcium Hypochlorite Packaging and Storage Packed in 10kg, 25kg, 40kg and 50kg Class II barrels, with PVC plastic bags or 50kg round iron drums marked with 5.1 oxidant inside. (2) In order to avoid humidity and direct sunlight, it should be properly sealed and stored at ambient temperature and well ventilated conditions, and it should not be mixed with organic substances, acids and reducing agents.
CaCL2 Dihydrate (72%, 74%, 77%) One type of inorganic salt that is both solid and liquid is calcium chloride. Solid calcium chloride can be a powder, granule, flake, or pellet with a white, crystallized form. It can be either dihydrate or anhydrous depending on the crystal water content. Clear and colorless, liquid calcium chloride is a solution. Due to the rapid dissolution, exothermic ability, ability to draw moisture from the air and surroundings, and ability to dissolve at extremely low temperatures of calcium chloride. CaCL 2 H20 Dihydrate (72%, 74%, 77%) Application Petroleum: drilling in oil fields, cementing, lubricating, and stabilizing mud layers. Most anions can be precipitated by calcium ions in water treatment.In addition to precipitating cations, chloride ions can oxidize ions to clean wastewater. Cryogen: A solution of calcium chloride is a crucial refrigerant used in freezers and ice makers. Used on parking lots, ports, roadways, and highways for deicing and melting snow. Pot is used as a dust-collecting and fog-removing agent on roads. As a dryer for materials such as sulfur dioxide, nitrogen, oxygen, and hydrogen chloride. In the process of making acrylic acid, ether, ester, and alcohol as a dehydrating agent. It can strengthen concrete's resistance to cold and increase its hardness.

Product quality index Industry standard (SH/T1627.1-1996), ZHONGHUI Chemical Enterprise Standard (ZH/S01.1-2013) Security Information Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30°C. Keep the container tightly closed. It should be stored separately from oxidizers, reducing agents, acids, alkalis, combustibles, and edible chemicals, and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable storage materials. Application The main purpose of acetonitrile is as a solvent. For example, as a solvent for extracting butadiene, a solvent for synthetic fibers and a solvent for some special coatings. Used in the petroleum industry to remove tar, phenol and other solvents from petroleum hydrocarbons. In the oil industry, it is used as a solvent for extracting fatty acids from animal and vegetable oils, and as a reaction medium for the recrystallization of steroid drugs in medicine. When a polar solvent with a high dielectric constant is required, a binary azeotropic mixture of acetonitrile and water is often used. Acetonitrile is an intermediate of medicine (vitamin B1) and spices, and a raw material for the manufacture of s-triazine nitrogen fertilizer synergist. It is also used as a denaturant for alcohol. In addition, it can also be used to synthesize ethylamine, acetic acid, etc., and also have many uses in textile dyeing and electronics industry. Acetonitrile is also used as a mobile phase solvent in analytical equipment such as chromatography.
