Basic Information
Scope
Scope: This standard applies to the sugarcane and beet processing industries, playing a role in adjusting pH values and clarifying sugar juice. Main technical content: Requirements for the quality of lime used as an industrial additive in the sugar industry. **Key technical requirements**: - **Superior grade**: - Effective CaO content (mass fraction, dry basis), w%: ≥97.0 - Magnesium and alkali metals (mass fraction): ≤3.6 - **First-grade**: - Effective CaO content (mass fraction, dry basis), w%: ≥95.0 - Magnesium and alkali metals (mass fraction): ≤3.6 - **Other requirements**: - Inorganic arsenic (as As), mg/kg: ≤3.0 - Fluoride (F), mg/kg: ≤150 - Lead (Pb), mg/kg: ≤2.0 - Acid-insoluble matter, w%: ≤1.0 - Burning loss, w%: ≤10.0 --- **Explanation of technical terms**: 1. **CaO**: Calcium oxide, also known as lime. 2. **w%**: Mass fraction (dry basis). 3. **As**: Arsenic. 4. **F**: Fluoride. 5. **Pb**: Lead. 6. **Acid-insoluble matter**: Substances that remain insoluble after treatment with acid. 7. **Burning loss**: Loss of weight during heating. --- **Translation notes**: - Technical terms are translated in accordance with their standard meanings. - Numbers and units are converted to Chinese units (e.g., mg/kg) when necessary. - The requirements for lime quality are presented in a clear and concise manner, ensuring the accuracy of the technical specifications. - The structure of the standard is preserved, with each technical item listed separately for clarity.
