Furan Anti-Acid Mortar vs. Potassium Silicate Mortar: Comparison, Applications, Installation, Standards, and Manufacturer Introduction
Which is Better: Furan or Potassium Silicate Acid-Resistant Mortar?
Furan Mortar and Potassium Silicate Mortar are both widely used for acid-resistant lining systems but have different chemical and physical properties. The selection depends on service conditions, chemical exposure, and performance requirements.
FURAN ANTI-ACID MORTAR
Advantages:
Outstanding resistance to a wide range of acids (except strong oxidizers like nitric acid), alkalis, and solvents
Excellent mechanical strength (compressive and flexural)
High temperature resistance up to 170°C
Impermeable to many aggressive chemicals
Disadvantages:
Sensitive to strong oxidizers
Application requires careful safety measures due to toxic fumes and handling
Higher cost compared to silicate mortars
POTASSIUM SILICATE MORTAR
Advantages:
Excellent resistance to acids (except hydrofluoric acid and strong alkalis)
Good bonding to ceramic brick and concrete
Cost-effective and mineral-based
Easy to apply and handle, non-toxic
Disadvantages:
Not suitable for strong alkali or hydrofluoric acid environments
Limited resistance to solvents and organic chemicals
Lower mechanical strength and temperature resistance (typically up to 120°C) than furan mortars
Typical Applications
Furan Mortar:
Chemical and petrochemical plants
Acid tanks, processing equipment, pickling lines
Flue gas desulfurization plants
Fertilizer and battery industries
Flooring and lining systems in areas with aggressive chemical exposure
Potassium Silicate Mortar:
Acid-resistant brick lining in tanks, vessels, and floors
Flue gas ducts
Chemical process plants
Wastewater treatment plants
Food processing industries (with acid but non-alkaline environments)
Application Method
Surface Preparation: Clean, dry, and roughen the substrate.
Mixing: Prepare mortar as per manufacturer’s instructions.
Laying: Apply a consistent layer of mortar on substrate and joints, position acid-resistant bricks/tiles, tap to align.
Joint Filling: Fill joints fully with mortar, clear excess.
Curing: Conditions depend on product; furan mortars require controlled curing and may need post-curing heating, while silicate mortars may set at ambient conditions.
