Professional FAQ: Essential Technical Insights

1. What is the material composition of Runhuabang High viscosity ceramic powder for chemical coatings and kaolin powder for paper making rubber fillers?

The ceramic powder is primarily nano-structured aluminosilicate, sometimes modified with titania or magnesium for enhanced stability. Kaolin is ultra-pure hydrous aluminum silicate, adjusted for controlled morphology and pH.

2. How is viscosity measured, and why is it crucial?

Viscosity is determined using rotary viscometers (ISO 3219) at 25°C. High viscosity enhances suspension stability and anti-sag in coatings/pulp, reducing defects and improving finished product performance.

3. What are the available particle size options?

Ceramic powder: D50 = 2.1 ± 0.15μm; Kaolin: D50 = 0.8 ± 0.05μm. Custom sizes available upon request to fit specific rheological or optical demands.

4. Which industry standards does the product comply with?

ISO 1248, ISO 9001, ISO 14001 for quality/environment management; ANSI B74.12 (mesh size); FDA 21 CFR (for food-contact applications); REACH (EU chemical safety).

5. What is the typical installation or usage protocol?

Pre-mix as dry powder or slurry in proper binder/pulp/rubber systems per recommended loading (10–37% by weight). For advanced coatings, disperse via high-shear mixer for 12–15 min.

6. What QC/QA testing supports consistent product performance?

Every batch is tested for viscosity, particle size, pH, brightness (ISO 2470), impurity profile (ICP-MS), and moisture. Optional third-party verification available on request.

7. What is the product’s service life in typical applications?

In coatings: 5–8 years before recoating; in paper: permanent enhancement of brightness and smoothness; in rubber: matching or outlasting matrix service interval.
