# Industrial Specification: Leather Edge Coating Application System

## 1. Technical Definition
Automated system for applying protective coatings to leather edges.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.8-1.2 bar (12-17 psi) coating pressure, 18-25°C operating temperature, 40-60% relative humidity**. Failure boundary: **Coating pressure exceeding 1.5 bar causes adhesive blow-through; temperature below 15°C causes viscosity-induced flow restriction; humidity above 70% causes moisture-induced adhesion failure**, Mechanism: **Adhesive rheology threshold violation (shear thinning beyond 1500 s⁻¹), thermal expansion mismatch (Δα=15×10⁻⁶/°C between applicator nozzle and coating material), capillary action failure at contact angles &gt;90°**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.

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

### Q: What types of leather products can this system handle?
**A**: The system accommodates various leather goods including belts, bags, wallets, and upholstery edges, with adjustable conveyor settings for different thicknesses up to the maximum specified.

### Q: How does the IR drying tunnel improve coating quality?
**A**: The infrared tunnel provides consistent, controlled curing that ensures uniform drying, prevents coating runs or bubbles, and enhances adhesion and durability of the protective edge finish.

### Q: What maintenance is required for the PTFE-coated application heads?
**A**: PTFE coating minimizes residue buildup; routine cleaning with recommended solvents and periodic inspection for wear ensures consistent application quality and extends component lifespan.
