Calcium hydroxide is used to neutralize acidic wastewater discharged from factories and is also used for neutralizing mining wastewater. At the same time, it has the effect of coagulating and precipitating dissolved heavy metals, and calcium hydroxide is used to remove acidic gases such as hydrogen chloride and sulfur oxides contained in exhaust gases from waste incineration plants. Furthermore, it is also used for the purification of water supply and sewage systems. 【Overview】 ■ Neutralization of acidic wastewater discharged from factories ■ Neutralization of mining wastewater ■ Coagulation and precipitation of dissolved heavy metals ■ Removal of acidic gases such as hydrogen chloride and sulfur oxides contained in exhaust gases ■ Purification of water supply and sewage systems *For more details, please refer to the related link page or feel free to contact us.

Among the five major elements of fertilizers, calcium and magnesium are made from lime. The term "magnesia" in magnesium lime fertilizer refers to magnesium, which is a component of chlorophyll. It is related to the movement of phosphoric acid and helps in the synthesis of fats. Lime contains a high amount of calcium and helps in neutralizing excess organic acids produced in the plant, generating chlorophyll, metabolizing carbohydrates, and promoting root growth. 【Overview】 ■ Lime contains a high amount of calcium ■ Neutralizes excess organic acids produced in the plant ■ Aids in the generation of chlorophyll, metabolism of carbohydrates, and promotion of root growth *For more details, please refer to the related link page or feel free to contact us.

Quicklime is used for neutralizing wastewater generated in manufacturing plants, as well as for producing propylene oxide, which is a raw material for pigments and pharmaceutical intermediates, and epichlorohydrin, which is a raw material for synthetic rubber, adhesives, and paints. Additionally, soda ash (sodium carbonate), which is a raw material for glass and chemicals, is produced by the ammonia-soda process, where lime is used to recover ammonia. It is also used in the paper industry for the regeneration of waste caustic soda. 【Overview】 ■ Quicklime (for caustic soda regeneration): Used for the regeneration of waste caustic soda ■ Quicklime (for light calcium carbonate): Used as a raw material for light calcium carbonate *For more details, please refer to the related links page or feel free to contact us.

Lime is widely used as a secondary raw material in steelmaking. Quicklime reacts with impurities such as silicon (Si), sulfur (S), and phosphorus (P) in iron within the converter or electric furnace to form slag, which removes impurities from the iron. It also serves as a cooling agent. In the case of high-quality steel, further refining is performed outside the furnace using quicklime after it exits the converter. 【Overview】 ■ 50% of quicklime production is used for steelmaking ■ Removes impurities from iron ■ Also acts as a cooling agent ■ In the case of high-quality steel ・ Further refining is performed outside the furnace using quicklime after it exits the converter *For more details, please refer to the related link page or feel free to contact us.
