Introduction
Interpretation of the core content of the standard
| Technical module | Key indicators | Test methods |
|---|---|---|
| Raw material quality | Viscosity 20-30s (25℃), storage period ≥1 year | GB/T 1723 |
| Glass fiber reinforced plastic construction | Glue content ≥45% (cloth), thickness ≥2mm | GB/T 2577 |
| Concrete tank | Compressive strength ≥60MPa, protective layer ≥25mm | 150mm³ test block |
Comparative analysis of material properties
Advantages of furan resin system: It has excellent corrosion resistance to 60% sulfuric acid, 20% hydrochloric acid and other media below 140°C, but attention should be paid to the restricted use of organic solvents such as acetone.
YJ type and XLZ type Proportion difference: The amount of mastic powder is 250-400g vs 200-250g, and the hydrofluoric acid resistant type needs to be modified with barite powder.
Key points of engineering technology
- Base treatment: concrete moisture content ≤6%, steel rust removal grade ≥St2
- Construction environment: temperature 15-30℃, humidity ≤80%, low temperature type allows construction at -5℃
- Curating cycle: 15 days at room temperature, heat treatment needs to be heated in steps of 40℃→60℃
Acceptance standard system
| Project | Allowance deviation | Detection tool |
|---|---|---|
| Fiberglass thickness | Ultrasonic thickness gauge | |
| Block flatness | 2m ruler | |
| Slope | Water splashing test |
Safety control measures
- Ventilation requirements: VOC concentration ≤100mg/m³
- Electrical protection: 36V explosion-proof lamps
- Emergency treatment: equipped with sodium hydroxide ethanol neutralizer
