| titleOfInvention | The method of half water producing building powdered gypsum by using phosphogypsum |
| abstract | The invention belongs to building materials fields, and in particular to the method for half water producing building powdered gypsum by using phosphogypsum.The cost of building gypsum plaster is produced using phosphogypsum dihydrate the technical problem to be solved by the present invention is to the prior art and quality is difficult to meet the requirements, and half water ardealite of industrial by-product, half water ardealite is difficult to use in building gypsum plaster.The technical solution that the present invention solves technical problem is to provide a kind of method of half water producing building powdered gypsum by using phosphogypsum.This approach includes the following steps：Alkaline matter is added in half water ardealite to be uniformly mixed, be homogenized in advance and store up, break up, calcining, grinding, being aged to obtain the final product.The method of the present invention can use the half water ardealite substitution natural gypsum or phosphogypsum dihydrate to produce building gypsum plaster completely, production cost is reduced, ardealite is turned waste into wealth, has effectively administered pollution and harm of the phosphogypsum slag to environment, with good environmental benefit, Social benefit and economic benefit. |
