One can opt for Furan Cement as a bedding and jointing mortar in acid resistant Bricks & Tiles lining works for chemical reaction vessels, floor, tank, etc.
Resistant: This mortar resists Salt, Oils, Greases, Non-Oxidizing Acids, Alkalies, Solvents, Detergents, etc. While carbon filled furan mortar resists flourid salted, hot & highly concentrated alkalies, hydrofluoric acid, etc. It can resist temperature up to 170oC (Max.)
Preparation of Mortar: In the mortar preparation, solution and powder are used. These two elements must be added in a ratio of 1 pbw and 3 pbw to get good working consistency. Depending upon the temperature and working conditions, the ratio can slightly vary.
Prepare Mortar in small batches: It is important to stir the solution thoroughly before using it. It must be added into mixing pan along with powder. Use spatula or trowel to mix the solution thoroughly. The solution must be mixed until you get a uniform mixture. All mortar from the pan must be used before preparing another batch.
Surface Preparation: It is important that the cement plastered surface must be slightly rough in line & level, clean and dry.
Setting / Curing
- Furan Resin Mortar self-hardens given to the chemical reaction caused by mixing the powder and resin.
- In 6-8 hours, an initial setting occurs at 30oC
- In 24-48 hours, Final Setting occurs at 30oC
- Curing time: 7 days at 30oC
Water must not be spilled over the bricks lining works prior to time when the mortar is completely cured.
