100mesh 25% Cr2O3 chromite powder for glass bottles green beer bottles
100mesh 25% Cr₂O₃ chromite powder is a professional inorganic colorant specially developed for glass coloring, widely applied in the mass production of green glass bottles, beer bottles, daily glass containers and architectural green glass. With stable chromium oxide content, uniform particle size and excellent high-temperature coloring performance, this chromite powder has become a cost-effective core coloring material for the glass packaging industry.
The product features a stable 25% chromium oxide content, which is the optimal proportion for producing standard green beer bottle glass. During the high-temperature melting process of glass, Cr₂O₃ forms a stable chromium ion color system, endowing glass products with uniform, transparent and bright emerald green tone. Different from ordinary colorants, it will not produce color deviation, color fading or uneven chromatic aberration after long-term high-temperature firing, ensuring consistent color uniformity for each batch of glass bottles and meeting the strict color standard requirements of food-grade beer packaging bottles.
Processed by precise 100mesh grading technology, the powder has moderate fineness, good fluidity and excellent fusion performance with glass raw materials. Its uniform particle size distribution enables the chromite powder to be fully mixed with quartz sand, soda ash and other glass raw materials, realizing rapid melting and uniform coloring in the kiln. It effectively avoids particle agglomeration, floating color and streaks on the glass surface, greatly improving the surface finish and yield of green glass bottles.
In addition to outstanding coloring effects, this chromite powder has excellent high-temperature resistance and chemical stability. It can withstand the high-temperature firing environment of 1500℃ without decomposition or deterioration, adapting to continuous industrial kiln production. Meanwhile, it is non-toxic, harmless and pollution-free, compliant with food-grade glass material safety standards, and will not precipitate harmful substances in beer and liquid storage scenarios, ensuring product safety and environmental protection.
Suitable for large-scale industrial production of green beer bottles, beverage glass bottles and daily green glass products, 100mesh 25% Cr₂O₃ chromite powder balances stable coloring performance, production cost and processing efficiency. It is a reliable and high-quality coloring additive for the modern glass manufacturing industry, helping manufacturers improve product appearance quality and market competitiveness.
