Surface Finish: Its fine texture provides a smooth surface finish, which is especially beneficial for consumer goods and packaging materials.
Reduced Production Costs: Using calcium carbonate as a filler reduces the amount of polymer required, lowering overall material costs.
2. Paints and Coatings
Calcium carbonate powder 325 mesh is widely used in the paints and coatings industry. Its applications include:
Pigment: It acts as a white pigment that improves the opacity and brightness of paints.
Filler: Calcium carbonate enhances the viscosity and texture of paint formulations, providing a smoother application.
Cost Reduction: By substituting more expensive pigments and extenders with calcium carbonate, manufacturers can produce cost-effective paint products without compromising quality.
3. Rubber Industry
In the rubber industry, calcium carbonate powder 325 mesh is utilized for its reinforcing properties. Key applications include:
Filler: It improves the strength and elasticity of rubber products, such as tires, seals, and gaskets.
Processing Aid: The powder aids in the processing of rubber compounds by improving flow and reducing viscosity, making it easier to mold and shape products.
4. Pharmaceuticals and Food Industry
Calcium carbonate powder 325 mesh has significant applications in the pharmaceutical and food sectors:
Calcium Supplement: It is used as a dietary supplement to provide essential calcium, crucial for bone health and development.
Antacid: Calcium carbonate acts as an effective antacid for treating indigestion and heartburn.
Food Additive: It is commonly used as a food additive (E170) to enhance nutritional content, improve texture, and serve as a pH regulator in various food products.
5. Agriculture
In agriculture, calcium carbonate powder 325 mesh plays a vital role in soil management:
6. Soil Amendment: It is used to neutralize acidic soils, improving soil structure and fertility.

It has been a long history that sodium alginate is used in starching, finishing and printing ,mainly printing .It ,as a reactive dye printing agent, has a special property.During reaction of fiber and reactive dye, the dye is fixed in fiber and printing agent do not attend this reaction .Otherwise, the agent will be fixed in fiber and make it hard,fragile and bad color.If you use sodium alginate as a printing agent,it not only affects the dyeing reaction but also makes the product outline clear, color bright,feeling smooth.This agent is also suitable for cotton,wool,silk and synthetic fiber.


Sodium alginate advantage:
1,High purity and stability.
2,Good filtration, high permeability rate.
3,Easy to color and good washing out.
4,The pattern is clear and bright.
