Inorganic water-softening bead |
摘要 |
An inorganic water-softening bead is disclosed having a density of from 36 to 46 lbs/cu ft consisting of at least 66% of sodium alumino silicate on an anhydrous basis; from 1 to 20% of sodium silicate; from 1 to 20% of a solubilizing agent, such as sodium sulfate; and the remainder being water. The sodium alumino silicate has a silica to aluminum oxide ratio of between 2:1 and 4:1 and a sodium oxide to aluminum oxide ratio of between 0.8:1 and 1:1. The sodium silicate has a silica to sodium oxide ratio of between 1:1 and 3.3:1.
