Packaging & Shipping
Packaging: Generally, sealed plastic woven bags or paper bags are used for packaging, with a net weight of 25kg, 50kg, etc. per bag. Packaging can also be customized according to customer needs.
Storage conditions: It should be stored in a dry, well ventilated warehouse to avoid moisture and rain. When storing, it should be separated from acids, flammable materials, organic substances, etc. to prevent chemical reactions or fires.
Shelf life: Under the condition of meeting storage conditions, the shelf life is generally around 1 year. If stored improperly, hydrated lime can easily absorb moisture and carbon dioxide and deteriorate, affecting its effectiveness.

Application
1. Construction industry: It is an important building material that can be used for masonry, plastering, painting, etc. Mortar made by mixing with sand, cement, etc. has good adhesion and strength, which can make buildings more sturdy. It can also be used to make lime soil, ternary soil, etc., for laying road base, improving the bearing capacity and stability of the road.
2. Environmental protection field: commonly used for the treatment of acidic wastewater and waste gas. In wastewater treatment, hydrated lime can neutralize the acid in the wastewater, adjust the pH value of the wastewater, and precipitate heavy metal ions, thereby achieving the goal of purifying the wastewater. In exhaust gas treatment, it can be used to absorb acidic gases such as reduce air pollution.
3. In the agricultural field, it can be used to improve acidic soil, neutralize acidic substances in the soil, adjust the pH value of the soil, and make the soil more suitable for crop growth. It can also be mixed with copper sulfate to prepare Bordeaux mixture for the prevention and control of plant diseases and pests, such as grape downy mildew and apple anthracnose.
4. Chemical industry: It is an important raw material for the production of chemical products such as calcium carbonate, calcium chloride, magnesium hydroxide, etc. In the paper industry, the sizing and bleaching processes used for paper can improve its water resistance and whiteness. In the rubber industry, as fillers and activators, it can improve the performance and quality of rubber.
