Advanced Manufacturing Process of High-Grade Lithopone Powder

The production of high-quality Lithopone pulver involves a sophisticated chemical manufacturing process, primarily based on the co-precipitation reaction between barium sulfide (BaS) and zinc sulfate (ZnSO₄). This meticulously controlled process ensures the formation of a precisely balanced composite pigment with desirable optical and physical properties. The journey begins with the careful preparation of highly purified raw materials. Barium sulfide solution is typically derived from barite ore (barium sulfate) reduction, while zinc sulfate is obtained from zinc ore processing. These solutions are then meticulously filtered to remove impurities, ensuring the final product's purity and whiteness. The core of the manufacturing process is the co-precipitation stage, where the two purified solutions are mixed under controlled temperature and pH conditions. This precise chemical reaction yields a slurry containing insoluble zinc sulfide and barium sulfate. The efficiency and quality of this step are paramount, as they directly influence the particle size distribution and crystalline structure of the nascent pigment. Following precipitation, the slurry undergoes a rigorous filtration process to separate the solid Lithopone cake from the liquid supernatant, which is then often recycled or treated for waste minimization.

After filtration, the wet cake of Lithopone pulver is subjected to a crucial calcination (roasting) step in specialized kilns at high temperatures, typically between 600°C and 800°C. This thermal treatment is critical for improving the pigment's whiteness, opacity, and weather resistance by altering its crystalline structure and removing residual impurities and volatile components. The calcination process is meticulously monitored to prevent agglomeration and ensure uniform particle growth, which is essential for optimal performance in end applications. Post-calcination, the hot calcined product is quenched in water, followed by wet grinding, which disperses the particles and refines their size. This step is vital for achieving the desired fineness and dispersibility of the pigment, ensuring easy integration into various matrices like paints and plastics. Subsequently, the slurry is washed thoroughly to remove any soluble salts and dried using rotary dryers or spray dryers, reducing the moisture content to specified levels. Finally, the dried Lithopone undergoes pulverization and micronization, where it is milled into a fine powder with a tightly controlled particle size distribution, ready for packaging. Throughout this entire process, adherence to international quality standards such as ISO 9001 and strict internal quality control protocols (e.g., spectrophotometric analysis for whiteness, particle size analysis, oil absorption tests) ensures that each batch of Lithopone Powder meets the highest industry benchmarks for consistency and performance. Our manufacturing excellence guarantees a product with optimal opacity, brightness, and dispersibility, essential for diverse industrial applications.

Technical Parameters and Grades of Lithopone Powder: A Comprehensive Overview

Understanding the technical specifications of Lithopone pulver is paramount for industrial buyers seeking to optimize their product formulations and achieve desired performance characteristics. Lithopone is typically graded based on its zinc sulfide content and processing method, with common grades including B301 (28-30% ZnS) and B311 (28-30% ZnS, with surface treatment for improved dispersibility). Key technical parameters define the quality and suitability of Lithopone for specific applications. Whiteness, often measured by a reflectometer against a standard, indicates the pigment's ability to reflect light across the visible spectrum, directly impacting the brightness of the final product. Hiding power, or opacity, quantifies the pigment's capacity to obscure the substrate over which it is applied, a critical factor in paints and coatings. This property is largely influenced by the refractive index difference between the pigment and its surrounding medium, as well as its particle size and distribution. Oil absorption value, expressed as grams of oil absorbed by 100 grams of pigment, is crucial for paint and ink formulations, affecting consistency, film formation, and gloss. A lower oil absorption generally indicates better dispersibility and higher pigment loading potential.

Other vital parameters for Lithopone pulver include pH value, which indicates its acidity or alkalinity and affects its compatibility with other raw materials in a formulation; volatile matter content, representing residual moisture; and water-soluble matter, which could impact the water resistance and stability of the final product. Particle size distribution is also critically important; finer particles generally offer better hiding power and gloss but can lead to higher oil absorption. Sieve residue measures the percentage of oversized particles, indicating the fineness of grinding and potential for agglomeration. Density, typically around 4.1 g/cm³, is relevant for volumetric considerations in formulation. Manufacturers adhere to strict quality control protocols, often involving advanced analytical techniques such as X-ray diffraction (XRD) for crystalline structure analysis, scanning electron microscopy (SEM) for particle morphology, and atomic absorption spectroscopy (AAS) for trace element analysis. These rigorous tests ensure consistency across batches and compliance with international standards like ISO 787 for general test methods of pigments and extenders.
