METHOD FOR PREPARING CALCIUM AND/OR MAGNESIUM HYDROXIDE, AND USE THEREOF |
摘要 |
A calcium and/or magnesium hydroxide having a water content of less than 50 % is characterized in that it has a specific surface area greater than 35 m<2>/g. A method for preparing said hydroxide comprises reacting CaO and/or MgO with an amount of water such that the resulting calcium and/or magnesium hydroxide has a water content of less than 50 %, in the presence of an amount of additive selected among glycols and/or amines. The method can be used in purifying acid gases in the building construction industry for the manufacture of mortars. |
