Chemical Grade Dry Hydrated Lime

Our Chemical grade dry hydrated lime is specially developed for chemical application scenarios, produced from high-purity lime raw materials through precise hydration, drying and classification grinding. The product has extremely low moisture, high purity and few impurities, in the form of dry fine powder. Our Chemical grade dry hydrated lime has stable calcium hydroxide content, low hydrochloric acid insoluble matter and heavy metal residue, and moderate reaction activity. It has few side reactions in chemical synthesis and high product purity, and is a high-quality alkaline raw material for fine chemical, calcium salt production, petrochemical and other fields.

Different from ordinary industrial hydrated lime, our Chemical grade dry hydrated lime optimizes the drying process and impurity control for chemical scenarios. The product moisture is controlled at an extremely low level, not easy to absorb moisture and cake, with good storage stability; meanwhile, coloring impurities such as iron and manganese and acid insoluble matter are strictly controlled to avoid introducing impurities that affect chemical reactions and product color. With stable purity and low impurity characteristics, our Chemical grade dry hydrated lime can effectively improve the yield of chemical products, reduce subsequent purification costs, and adapt to various fine production needs.

● Calcium salt chemical synthesis: Used as calcium source to produce various calcium salt products such as calcium propionate, calcium lactate and calcium citrate, with stable reaction and high product purity.

● Organic synthesis acid scavenger: Neutralize acid generated during organic synthesis, promote forward reaction and reduce side reactions.

● Petrochemical refining: Neutralize acidic substances in oil products, remove impurities, and improve oil product stability and purity.

● Fine chemical intermediates: Used for pH adjustment and acid scavenging in pharmaceutical intermediates and dye intermediates synthesis, with few impurities not affecting the reaction.

We can customize Chemical grade dry hydrated lime with different indicators according to customers' specific chemical process needs. We can adjust calcium hydroxide purity, fineness, moisture and impurity control level, and also optimize activity and particle size distribution for specific reactions. Whether it is conventional chemical grade for mass production or special index requirements in R&D stage, we can provide corresponding product solutions to adapt to different reaction systems and production processes, helping customers improve product quality and production efficiency.

We have established an exclusive quality control system for chemical-grade products, strictly controlling impurity indicators from raw materials to finished products. Raw materials select high-calcium low-impurity limestone, and dedicated chemical-grade production lines are used in production to avoid cross-contamination; the finished product laboratory is equipped with precision testing equipment to test key indicators such as calcium hydroxide content, hydrochloric acid insoluble matter and heavy metals batch by batch. Each batch of products is accompanied by a composition inspection report to ensure stable and traceable quality, meeting the raw material quality access requirements of chemical enterprises.

The production and testing of our Chemical grade dry hydrated lime strictly follow relevant industry standards such as HG/T 4120-2009 Industrial Calcium Hydroxide, and core indicators are better than general grade requirements. Third-party authoritative inspection reports (such as SGS, Huace) can be provided according to customer needs, supporting customers' supplier qualification audit and system certification, helping customers successfully enter the high-end chemical supply chain.
