Abstract
Description
technical field
[0001] The invention relates to the technical field of building materials, in particular to a phosphogypsum base material imitation wood floor and a preparation method thereof. Background technique
[0002] In the phosphoric acid production process, every ton of P produced 2 o 5 Five tons of phosphogypsum are produced by-product, and the annual by-production of phosphogypsum by medium-sized phosphoric acid production enterprises is about 3.5 million tons. So much phosphogypsum not only requires a large slag dump, but also causes water pollution. At present, the most commonly used phosphogypsum treatment methods are as follows:
[0003] The first method: Phosphoric acid paste is used to backfill the pit. According to statistics, when phosphogypsum is not used to backfill the mine shaft, the filling cost of the mine shaft accounts for 1 / 3 of the mining, and the filling material accounts for 80% of the filling cost. If phosphogypsum is used to fill the mine ...
