Product Introduction

Product Description

 

Our Chemical Grade Quick Lime Powder is specially developed for chemical application scenarios, produced from high-purity low-impurity limestone as raw material, processed through clean calcination and fine grinding. The product has high purity and few impurities, with strict control of harmful impurities such as iron, silicon and heavy metals. Our Chemical Grade Quick Lime Powder can participate in various chemical reactions as a high-purity calcium-based raw material, with few impurities not causing side reactions, which can effectively improve target product yield and purity and reduce subsequent purification costs.

 

In response to the strict requirements of chemical production for raw material purity, we have established a chemical-grade exclusive production system, avoiding impurity introduction from ore source selection to finished product packaging, ensuring each batch of Chemical Grade Quick Lime Powder meets chemical-grade quality standards. The product has stable composition and small fluctuation between batches, and can be widely used in calcium salt synthesis, organic chemical, petroleum refining, fine chemical and other fields, making it a high-quality basic raw material for chemical production.

Qualification Certification

 

The production and testing of our Chemical Grade Quick Lime Powder strictly follow relevant industry standards such as HG/T 4205-2024 Industrial Calcium Oxide, 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.

 

Quality Control

 

We have established an exclusive quality control system for chemical-grade products, implementing special line production and special area storage. Raw materials select exclusive high-purity ore layers, and clean calcination process is adopted in production to avoid impurity introduction; the finished product laboratory is equipped with precision testing equipment to test key indicators such as available calcium, hydrochloric acid insoluble matter, iron 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.

 

Customization Capability

 

We can customize Chemical Grade Quick Lime Powder with different indicators according to customers' specific chemical process needs. We can adjust available calcium purity, fineness 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.
