Applications & Uses
- Applications
- Typical Uses
Carbo-Chemester® Mortar is recommended for process vessels, storage tanks, scrubber towers and dryers requiring the chemical, physical or thermal resistance of chemical resistant brick construction. Carbo-Chemester® Mortar is an excellent mortar for carbon brick lined structures designed to contain nitric and hydrofluoric acid solutions. It is also recommended for trenches, sumps and containment dikes exposed to hydrofluoric acid in combination with strong caustics, organic acids, chlorine, and nitric, chromic or sulfuric acids.
- Application of The Carbo-chemester Mortar
Carbo-Chemester® Mortar can be used as a mortar for chemical resistant brick construction, as a bed joint over an impervious membrane or with RED FURNANE® SETTING BED, Data Sheet 5-55PI.
Brick Joints : Install the mortar using conventional bricklaying techniques. Apply the mortar to two sides of the brick forming a “V” profile. Place the brick on the setting bed and slide it into place to attain a 1/8” (3.2 mm.) wide joint. Strike excess mortar before the mortar begins to set.
Bed Joint : When using Carbo-Chemester® Mortar as a bed joint over an asphalt membrane, apply a coat of AMPVAR PRIMER Base (without accelerator) over the membrane and allow it to dry. Typical drying times of AMPVAR PRIMER Base are 2-1/2 hours at 65°F (18°C) or 1 hour at 85°F (29°C). Apply the mortar with a 3/16” V-notched trowel held at a 45 degree angle. Place a sufficient amount of mortar to provide a continuous bond coat to the specified thickness. Do not apply more mortar than can be covered in 10 to 15 minutes at 75°F (24°C).
Waxing of The Brick for Floors
- Carbo-Chemester® Mortar can stain red shale brick during installation. Paraffin wax can be applied to the surface face of the brick to eliminate staining.Carbo-Chemester® Mortar can stain red shale brick during installation. Paraffin wax can be applied to the surface face of the brick to eliminate staining.
- The wax coating and excess mortar are removed from the surface of the brick by steam cleaning. Use a minimum 60 psi. nozzle pressure for cleaning. Allow 24 hours at 65°F (18°C) or 12 hours at 85°F (29°C) minimum cure time before steam cleaning
- Mixing of The Carbo-chemester Mortar
Mixing of the components should be with a KOL type mixer with a 5-gallon capacity. The mixing speed should be between 60 and 75 RPM.
108 lb. 8 oz. (49.2 kg.) Unit
- Place 128 fluid ounces (3.8 liters) of CARB°Chemester® Mortar Resin in the 5-gallon capacity mechanical mixer.
- Add approximately 1/2 of one of the 13 lb. 10 oz. (6.2 kg.) bags of Carbo-Chemester® Mortar Powder. Mix thoroughly for approximately two minutes.
- Add 1.4 fluid ounces (41 ml.) CARB°Chemester® Mortar Hardener to the resin/ powder slurry. Mix thoroughly for approximately two minutes.
- Add the balance of the Carbo-Chemester® Mortar Powder from the 13 lb. 10 oz. (6.2 kg.) bag. Mix the combined components for approximately two minutes or until all the powder is thoroughly dispersed.
Note: The amount of the powder may be varied slightly to obtain the desired consistency. Please note that decreasing the powder component will decrease the estimated unit coverage.
Typical Working & Setting Times of The Carbo-Chemester® Mortar
