industrial grade hydrated lime for wastewater treatment industry
Industrial grade hydrated lime (calcium hydroxide) is an important basic chemical raw material, widely used in multiple industrial fields due to its alkalinity, precipitation performance, and chemical activity. Its main uses include:
Wastewater treatment: used to neutralize acidic wastewater, adjust pH value, and precipitate heavy metal ions to purify water quality. Metallurgical industry: In non-ferrous metal smelting (such as copper and nickel), it serves as a pH regulator to help remove impurity ions and improve metal purity.
Building materials: As a component of lime mortar or concrete, it enhances bonding and durability, and is commonly used in masonry and plastering.
Paper industry: used in the pulp making process to regulate alkalinity and precipitate impurities, improving paper quality.
Sugar industry: used to clarify sugar juice, neutralize acidic substances, and precipitate impurities to improve the purity of sugar.
Leather manufacturing: In the processes of hair removal and softening, the structure of hair is destroyed and the physical properties of leather are improved.
Pesticide production: As a raw material for fungicides such as Bordeaux mixture, it effectively controls crop diseases through copper ions.
Food processing: Food grade products are used as coagulants or pH regulators in specific processes (such as Century egg and tofu production).
Rubber and Plastic Industry: As a filler, it enhances hardness, wear resistance, and cost-effectiveness.
Flue gas desulfurization: Neutralizes acidic gases (such as sulfur dioxide) in coal-fired flue gas to reduce environmental pollution.
Electronics and Glass Industry: Used for producing high-purity calcium carbonate and other materials to improve the performance of electronic components or glass products.
Petrochemical industry: Processing acidic impurities in oil products to improve fuel stability and equipment durability.
