What is the factory wholesale price of hydrophobic rock wool board for external insulation of electrolytic cells? The external insulation materials for electrolytic cells are mainly divided into two categories: high temperature type (aluminum electrolytic cells) and medium low temperature type (hydrogen production/chemical electrolytic cells). The core requirements are low thermal conductivity, high temperature resistance, chemical corrosion resistance, and stable strength. However, the actual price of rock wool board may fluctuate due to factors such as density, thickness, and purchase quantity. Hydrophobic rock wool board is the preferred cost-effective option for external insulation of electrolytic cells, with good insulation, non absorbent, strong fire resistance, durability, and very stable effect. The key advantages of rock wool board in terms of hydrophobic and waterproof performance compared to ordinary rock wool board are:
True hydrophobicity rate ≥ 98%, water falls on it as beads rolling off, does not absorb water
Even if the environment is humid and there is condensation water, the insulation performance remains basically unchanged
Ordinary rock wool becomes useless when it gets damp, while hydrophobic type can be used outdoors/in humid environments for a long time
Stable insulation: The temperature of the outer wall of the tank is well controlled, resulting in low energy consumption
Not afraid of moisture: workshop moisture and condensed water do not affect
Fire prevention is absolutely reliable: hydrogen production and electrical environment are the most reassuring
Convenient construction: easy to cut, easy to wrap, moderate strength
Long lifespan: Normal use for 5-10 years without replacement
External insulation of electrolytic cells belongs to industrial applications, with strict requirements for hydrophobicity (≥ 98%) and temperature resistance (above 600 ℃), and the price will be higher than that of ordinary building rock wool boards.
