In industrial settings, high-humidity and dust-prone conditions often undermine material stability and equipment efficiency. However, rock wool boards, with their unique properties and structure, effectively adapt to these harsh environments through moisture resistance, corrosion resistance, and dust resistance.
For high-humidity environments, rock wool boards rely on a dual "chemical stability + functional enhancement" mechanism. Their core component, silicate (an inorganic material), boasts stable chemical properties and water insolubility. Unlike organic alternatives like polystyrene boards, they won’t absorb moisture, soften, or decompose in humid conditions (even at over 80% relative humidity), with mechanical properties declining by less than 5%. Silicate also inhibits mold growth, suiting food and pharmaceutical factories with strict hygiene needs. Industrial-grade hydrophobic rock wool boards, added with organosilicon water repellents, form a surface film with over 98% hydrophobicity, repelling rainwater and vapor. For instance, they prevent vapor from entering insulation layers around chemical plant cooling towers, avoiding thermal conductivity increases and energy waste. Additionally, they resist acids and alkalis, enduring corrosive vapors in humid settings like pharmaceutical fermentation workshops without degradation.
To tackle dust-prone environments, their structural and performance advantages shine. The three-dimensionally interwoven fiber structure has small, uniform micron-sized pores. Most dust is carried away by airflows, and residual dust rarely clogs pores—critical for maintaining insulation in dusty mechanical workshops. Their smooth surface (especially faced industrial boards) allows easy dust removal via sweeping or wiping, reducing maintenance costs compared to dust-prone glass wool. With compressive strength of 40-150kPa and flexural strength ≥15kPa, they resist abrasion from metal or ore dust, as seen in mine processing workshops where they withstand dust impact without damage.
Notably, rock wool boards synergize to handle combined high-humidity and dust environments (e.g., paper or textile mills). Their hydrophobicity prevents "wet dust" formation—wet dust solidifies, accelerates corrosion, and is hard to clean. Meanwhile, stable chemistry and mechanical strength ensure long-term performance of insulation, soundproofing, and fire resistance. For example, in printing and dyeing workshops with high humidity and dye dust, rock wool wall fillings block vapor, resist dust corrosion, and reduce noise, fully meeting composite environment demands.
| Material | Waterproof Principle | Water Absorption Rate | Applicable Environment | Limitations | Waterproof Lifespan |
|---|---|---|---|---|---|
| Hydrophobic Rock Wool Board | Hydrophobic treatment reduces water adsorption | ≤5% (≤3% for high-quality products) | High-humidity insulation scenarios | Requires combination with other waterproof layers | 15-20 years |
| Concrete | Dense structure formed by adjusting mix ratio | Impermeability grade P6-P12 | Structural waterproofing | May crack under stress | 10-30 years |
| Coating Types | Forms continuous waterproof film | Almost no water absorption | Small-area scenarios | Breathability/UV resistance issues | 10-15 years |
| Metal Materials | Non-absorbent by nature | 0% | Large venues | Joints prone to seepage | 20-50 years |
