A Comprehensive Overview of the Top Ten Application Fields of Calcium Carbonate(II)

Field 6: Food and Medicine (High-purity Specialized Calcium Carbonate)

Core Function

1. In terms of food (compliant with GB 1886.214 standard): used as a calcium supplement and fortifier, it can also improve texture and prevent adhesion in baking, dairy products, and candies;
2. In terms of medicine: as a raw material for calcium tablets and a disintegrant for tablet filling, it can also be used to neutralize stomach acid and alleviate acid reflux symptoms;
3. Auxiliary carrier: High purity porous aragonite structured calcium carbonate can be used as a drug sustained-release targeted carrier material.

Hard Rule

It is necessary to strictly control the content of heavy metals lead and arsenic to below the limit, prohibit the use of industrial grade modifiers, and only use food grade or pharmaceutical grade purified powders.

Field 7: Personal Care Products for Daily Use (Toothpaste, Cosmetics, Skincare Products)

Core Function

As the main friction agent of toothpaste, it gently removes dental plaque without damaging enamel; Affordable toothpaste often uses coarse and heavy calcium, while sensitive teeth whitening toothpaste uses ultra-fine light calcium;

2. It can play the role of filling, thickening and shading in color makeup and face cream, adjust the skin feeling of use, and improve the stability of cream molding.

Key Selection Points

The toothpaste field usually uses 400-2000 mesh graded calcium powder; It is recommended to use ultra-fine and heavy metal free light calcium for skincare products.

Field 8: Environmental Governance (Flue Gas Desulfurization, Wastewater Treatment, Soil Remediation)

Core Function

1. Flue gas desulfurization process in power plants and steel mills: The gypsum by-product generated by neutralization reaction with SO ₂ can be reused as a resource;
2. Industrial acidic wastewater treatment: adjust pH value, adsorb heavy metal ions and suspended solids in water;
3. Acidic soil improvement: Neutralize soil acidity, supplement calcium elements, and use them for remediation and treatment of heavy metal contaminated land.

Key Selection Points

Low cost ordinary heavy calcium can be selected for large-scale desulfurization and water treatment scenarios; The scenario of deep adsorption of heavy metals can be combined with a small amount of nano calcium carbonate.

Field 9: High End Materials for New Energy (Iithium Batteries, Photovoltaics)

Core Function (Applicable only to Nano Calcium Carbonate)

1. Lithium battery electrolyte additive: adsorbs HF impurities, stabilizes SEI film structure, and extends battery cycle life;
2. Lithium battery separator coating: Sheet shaped ultrafine calcium can improve the heat resistance and thermal insulation safety of the separator;
3. Photovoltaic packaging adhesive: nano calcium can adjust the thixotropy and anti-aging properties of the colloid, and enhance the overall weather resistance of the module.

Selection Requirements

To meet the standards of high purity and low impurities, wet modified nano calcium is used with a water content controlled at ≤ 0.1%.

Field 10: Sealing and Adhesive (MS Adhesive, Silicone Adhesive, Epoxy Adhesive)

Core Function

1. Give the system good thixotropy to ensure that it does not flow during gluing and does not sag during facade construction;
2. Improve the elongation, crack resistance, and adhesive strength of colloids;
3. Replace white carbon black and reduce the production and manufacturing costs of high-end sealants.

Key Selection Points

The main recommendation is to use active nano calcium carbonate, compounded with 5% -10% ultrafine heavy calcium to reduce viscosity and control overall costs; The filling range is 40% -60%.
