Product Description
Recyclable And Eco-friendly Rock Wool Boards With High Waterproof
Performance
Hydrophobic rock wool board is a thermal insulation material that
improves its water resistance through special processes, such as
adding hydrophobic agents. It retains the core advantages of rock
wool while offering enhanced moisture resistance and durability.
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.
Performance
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.
Waterproof Performance Comparison
| 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 |
