This is chemical setting Furan based chemical resistant mortar which is combination of Liquid and Powder, when mixed in proper proportion from workable mortar which after setting and curing give of liquid and give black highly cross linked composites. Furan When set and cured is resistant to highly corrosive acids, alkalis and to powerful organic solvents such as ketones, Aromatic and Chlorinated solvents. It has extreme resistant to Acidic & alkalis, Salts, Greases and Detergents. It resists to Organic & Inorganic acids at their boiling temperature. It is suitable against mild chlorine Gas (dry) phosphorous trichloride, pyridine at room temperature. Furan is especially useful where resistance to mixed media such as aqueous acids /alkalis and organic solvents is needed in chemical plant process and waste streams. Carbon filled Furan is used against corrosive effect of hydrofluoric acid & its salts. PREPARATION OF FURANE MORTAR : Mortar consist of Furan solution and Furan powder. The average mixing ratio necessary to obtain mortar with good working consistency is 1 part by weight Solution & 3 part by weight powder. The ratio will vary slightly depending on temperature and working conditions.Stir the liquid thoroughly before using. Place liquid in a suitable shallow mixing pan. Add powder by weight in the solution mix thoroughly and rapidly until all lumps are dispersed and the mortar is completely homogenous. Spread out the mortar in a thin layer, not more than ¾ thick, to dissipate the heat of reaction and lengthen the working life. Batch size can be varied depending upon the temperature and the speed with which the masons are working. Very large batches will become stiff quite rapidly. Make sure that all the Furan Motrar is used from the pan before another batch is mixed.When working at temperature above 40 C, very small batches not more than 2 Kgs, should be prepared. When working at temperature below 15C the liquid should be kept warm.
