# Industrial Specification: Industrial Grade Sodium Hydroxide Flake

## 1. Technical Definition
High-purity caustic soda flakes for industrial chemical processes

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-100°C, 0-1.5 MPa pressure, 0-50% concentration in aqueous solution**. Failure boundary: **Melting point at 318°C, decomposition above 400°C, deliquescence at 75% relative humidity, corrosion rate exceeds 0.5 mm/year on carbon steel at 80°C**, Mechanism: **Thermal decomposition into sodium oxide and water vapor above 400°C, hygroscopic absorption leading to caking and flow obstruction, electrochemical corrosion of ferrous alloys via OH- ion attack**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is the typical NaOH purity percentage for industrial grade sodium hydroxide flakes?
**A**: Industrial grade sodium hydroxide flakes typically have NaOH purity ranging from 98% to 99%, with exact specifications varying by manufacturer and application requirements.

### Q: How does chloride content affect industrial chemical processes using sodium hydroxide flakes?
**A**: High chloride content (measured in ppm) can cause corrosion in equipment and affect product quality in sensitive chemical processes, making low chloride specifications important for many industrial applications.

### Q: What are the storage and handling considerations for sodium hydroxide flakes based on bulk density?
**A**: Bulk density (kg/m³) determines storage volume requirements and handling characteristics. Higher bulk density allows for more efficient storage and transportation, while proper sealed containers prevent moisture absorption and caking.
