# Industrial Specification: Admixture Storage Tank

## 1. Technical Definition
A container designed to store liquid or powdered admixtures before they are precisely dosed into a production process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 bar (gauge pressure)**. Failure boundary: **2.5 bar internal pressure or -0.3 bar vacuum**, Mechanism: **Yield strength exceedance of AISI 304 stainless steel (205 MPa) at 2.5 bar or buckling collapse at -0.3 bar vacuum due to Euler critical load**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| P | Internal Pressure | Engineering Constant |
| D | Diameter | Engineering Constant |
| t | Wall Thickness | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Polymerization of polycarboxylate ether admixtures at 40°C+ | 8 | Viscosity increase to 5000 cP causing pump cavitation | Jacketed cooling system maintaining 15-25°C with PID control |
| Electrochemical corrosion at chloride concentration &gt;500 ppm | 8 | Pitting corrosion at 0.5 mm/year rate leading to wall perforation | 316L stainless steel construction with cathodic protection at -850 mV vs Ag/AgCl |

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

### Q: What materials are best for corrosive admixtures?
**A**: For corrosive admixtures, SS316L stainless steel offers superior chemical resistance, while polyethylene (PE) and polypropylene (PP) provide excellent corrosion resistance for various chemicals at lower cost.

### Q: How does the agitator improve admixture storage?
**A**: The agitator or impeller prevents settling and separation of powdered or liquid admixtures, ensuring consistent mixture quality and accurate dosing throughout the production process.

### Q: What maintenance features should I look for?
**A**: Essential maintenance features include a manhole or cleaning port for easy access, smooth interior surfaces to prevent residue buildup, and durable construction materials that withstand regular cleaning and chemical exposure.
