# Industrial Specification: Vegetable Tanning Extract Powder

## 1. Technical Definition
Natural tannin-rich powder for traditional leather processing

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **15-85°C, 0.1-3.0 MPa, 40-75% relative humidity**. Failure boundary: **Thermal degradation at 95°C, hygroscopic clumping at 85% RH, pressure-induced compaction at 3.5 MPa**, Mechanism: **Protein-tannin complex denaturation above glass transition temperature (Tg=90°C), hydrogen bonding saturation causing capillary condensation, irreversible particle deformation exceeding yield strength (σ_y=4.2 MPa)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Ambient humidity exceeding 85% RH during storage | 8 | Hygroscopic absorption leading to powder caking and flow obstruction | Hermetic storage vessels with desiccant cartridges maintaining &lt;60% RH |
| Mechanical vibration at 120 Hz resonance frequency during pneumatic transport | 8 | Particle segregation and density stratification in silos | Anti-segregation baffles with tuned mass dampers at 115-125 Hz frequency range |

## 3. Key Technical Parameters

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

### Q: What are the main benefits of using vegetable tanning extract powder?
**A**: Vegetable tanning extract powder offers natural, eco-friendly leather processing with rich tannins from quebracho, chestnut, and mimosa sources. It provides traditional leather characteristics, improved durability, and is biodegradable compared to synthetic alternatives.

### Q: How do I determine the right particle size for my leather processing needs?
**A**: Particle size (measured in mesh) affects dissolution rate and penetration. Finer powders dissolve faster for even tanning, while coarser grades offer controlled release. Our technical team can recommend based on your leather type and processing method.

### Q: What is the typical tannin content and how does it affect leather quality?
**A**: Our vegetable tanning extract powder typically contains 60-70% tannin compounds. Higher tannin content ensures better leather penetration, improved strength, and enhanced resistance to heat and decay, resulting in durable, high-quality leather products.

## 6. Manufacturing Compliance
