1.Calcium Powder
Cement and concrete production: It is a key raw material.
Artificial marble/tile adhesive: It serves as a primary filler.
Interior and exterior wall putty: It provides filling and sanding properties.
2.Talc Powder
Plastics Industry (especially Polypropylene):
Reinforcement Agents: Significantly improve the stiffness, heat resistance (heat distortion temperature), creep resistance, and dimensional stability of plastics. Talc is often used to fill PP in automotive dashboards, bumpers, and other applications.
Nucleating Agents: Modify the crystal structure of PP, increasing its transparency and mechanical strength.
Coatings Industry:
Suspending Agents and Fillers: Their flake-like structure prevents pigment settling and improves coating storage stability.
Improving Paint Film Properties: Enhances water and corrosion resistance and reduces air and moisture permeability.
Matting Agents: Used in some coatings to adjust gloss.
Paper Industry:
Fillers and Coatings: Improve paper's smoothness, opacity, printability, and ink absorption.
3.Kaolin
Paper Industry (Traditionally the Largest Application):
Coating: It is the most important pigment in paper coatings, significantly improving the surface smoothness, gloss, whiteness, and printing properties of paper.
Filler: It fills paper, increasing opacity and density.
Ceramic Industry (Oldest Application):
Main Raw Material: It is a core raw material for the manufacture of household ceramics, sanitary ceramics, industrial ceramics, and electrical ceramics, providing the plasticity required for molding and mechanical strength after sintering.
Coating Industry:
Functional Filler: Its flake structure improves the suspension, brushability, and weather resistance of coatings. It is commonly used in latex paints, primers, etc.
4.MetaKaolin
Main Application Areas:
High-Performance Concrete and Mortar (Core Application):
Reinforcement and Toughening: Significantly improves the compressive and flexural strength of concrete.
Improving Durability: Significantly reduces concrete permeability, thereby improving its resistance to chloride ion attack, sulfate attack, and abrasion.
Inhibiting Alkali-Aggregate Reaction: Effectively consumes alkali in cement, preventing harmful alkali-aggregate reactions and extending the life of the structure.
Early Strength Enhancement: Rapid reaction speed, providing early strength development.
Calcium powder is a master of economical and practical fillers.
Talc is a performance-enhancing expert for lubrication and stiffness enhancement.
Kaolin is a traditional all-rounder, indispensable in papermaking and ceramics.
Metakaolin is a high-tech active powder, specializing in high-performance cement and advanced materials.
