Kaolin Clay – High Whiteness Layered Functional Mineral Powder

Time : 2026-10-10

Kaolin clay, also known as china clay, is a natural layered hydrated aluminosilicate mineral. Processed through ore dressing, purification and ultra-fine grinding, it is an indispensable environmentally friendly non-metallic mineral raw material. It is widely used in architectural coatings, ceramic manufacturing, papermaking filling, rubber and plastic modification, daily chemical cosmetics and refractory materials. It features core advantages of high whiteness, fine texture, excellent plasticity, stable suspension performance and outstanding cost performance.

  • Meticulous craftsmanship: Two production paths ensure controllable and traceable quality

(1)Raw ore simple grinding and drying processing

Natural kaolin raw ore is processed through simple crushing, drying and conventional grinding screening without deep purification and calcination. With low processing cost and general whiteness and impurity control, it is suitable for ordinary mortar filling, low-grade interior wall putty, common pottery blank making and other cost-prioritized basic application scenarios.

(2)Wet purification and high-temperature calcination treatment

Adopt precise processes including ore washing desanding, sedimentation impurity removal, magnetic iron removal, spray drying, high-temperature calcination and airflow ultra-fine grading. Mine tailings can be recycled for construction backfill to realize green cyclic mining production. Finished calcined kaolin features ultra-high whiteness, low iron impurities, uniform particle size and stable suspension, meeting strict standards of high-end latex paint, coated paper, fine ceramics, cosmetic raw materials and insulating refractory products.

  • Core Features: Six Major Advantages Underpin "Abundant Value"

(1)Environmentally friendly and low harmful impurities, compliant and worry-free

Strictly control heavy metals, soluble salts and radioactive substances, fully compliant with EU REACH, RoHS and national building material and daily chemical safety standards. Non-toxic and non-irritating, safe for indoor decoration and personal care product applications.

(2)Weather-resistant and lightfast, long-lasting and stable

Excellent anti-ultraviolet and anti-aging performance. No yellowing, chalking or fading after long-term outdoor exposure. Physical and chemical indicators remain stable under high temperature, humidity and cold-hot alternating environments.

(3)Acid and alkali resistant and corrosion resistant

Stable chemical structure in a wide pH range, with excellent compatibility with cement, acrylic emulsion, resin and various solvent systems. Hardly reacts with acidic and alkaline substances, making it an ideal filler for anti-corrosion coatings and engineering ceramics.

(4)Fine lamellar structure, outstanding hiding & suspension performance

Unique microscopic lamellar structure endows coatings with strong hiding power and anti-settling ability. It effectively improves coating flatness and ceramic glaze smoothness. A small dosage can greatly enhance product texture and reduce raw material consumption.

(5)Good dispersibility and convenient construction

Uniform superfine powder, no agglomeration when stirred in water-based and solvent-based systems. Adaptable to paint spraying, putty scraping, ceramic blank rolling and plastic extrusion forming processes.

(6)Batch stability and controllable quality

Formal manufacturers implement ISO9001 quality management system, strictly control batch whiteness, particle size, iron content and viscosity indicators, eliminating construction defects such as paint sagging and ceramic pinholes caused by raw material performance fluctuations.

  • Empowering all industries: From basic building materials to high-end manufacturing, covering all sectors

Interior and exterior wall latex paint, anti-crack putty: improve hiding power, prevent pigment precipitation and optimize construction performance;Daily ceramics, sanitary ware and art porcelain: refine glaze texture, reduce firing shrinkage and improve finished product yield.

(1)Papermaking and Rubber Plastic Industry

Coated paper and printing paper filler: improve paper smoothness, ink absorption and printing definition;Rubber sheets and plastic daily products: enhance dimensional stability, surface smoothness and aging resistance.

(2)Daily Chemical and Refractory Field

Cosmetic substrates such as facial mask and body scrub: mild texture, soft skin feeling and safe formula compatibility;High-temperature refractory bricks and insulating castables: improve thermal stability and high-temperature resistance of kiln linings.
