Abstract
Description
Claims (1)
- A kind of precipitation of silica technology adopts the natural subsidence method, adds and helps precipitation agent.Comprise in the settling process:A, add people's bicarbonate of ammonia (or volatile salt) for helping precipitation agent, addition is the 1.0-2.0% of slurries by weight.B, mix rod, slurries are stirred propose outside the container after 10 minutes with the magnetic iron staff, totally standby with flushing with clean water.Behind C, the precipitated and separated, lower sediment is with clear water fine laundering precipitation surface 2 times, remove scrubber layer after, lower sediment is after mechanical separation, dry under normal pressure and 600-650 ℃ of temperature, pulverizing the back slightly is finished product.
