Abstract
Provided is ardealite putty powder. Ardealite is solid waste during a phosphoric acid production process. Because various toxic pollutants are contained in the ardealite, serious pollution can be caused around a field if the ardealite is stacked for a long time. By innocent treatment of the ardealite in advance, after impurities and harmful substrates are removed, the ardealite is used as base materials, ardealite building putty with high additional value is prepared, and the ardealite putty powder is a novel path for ardealite resource utilization.
Description
Technical field
The present invention relates to a kind of phosphogypsum putty powder, belong to the putty powder preparing technical field.
Background technology
Phosphogypsum is the solid waste in production process of phosphoric acid, owing to wherein containing multiple poisonous pollution substance, its long-term stacking meeting is caused serious pollution on every side to the place, but can become good material of construction to just becoming after its harmless treatment, the impact of phosphogypsum self-characteristic (complicated component, color is relatively poor, the goods voidage is high), the phosphogypsum product is difficult to be used in other outer industry of building trade, but building putties is the indispensable material of construction work, and its quality product and technical feature have considerable influence to construction and construction quality.Cohesive strength is low, drying is slow for traditional architecture putty (107 glue, talcum powder preparation), long construction period, efficient are low, its quality wayward and in construction period and use procedure the carcinogenic toxic substance such as release formaldehyde, developed country bans use of already, also belongs to building materials out of category in China.
Summary of the invention
The present invention is to provide a kind of phosphogypsum putty powder, by to phosphogypsum harmless treatment in advance, after removal of contamination and objectionable impurities, it is being polished into 200 orders-400 purpose powder, as base material, the higher phosphogypsum building putties of preparation added value is the new way of phosphogypsum resource utilization.
Technical solution of the present invention is as follows, with following raw material: phosphogypsum 88%, talcum powder 10%, redispersable latex powder, retardant 0.3%-0.35%, calcium hydroxide 0.05%-0.1%, ether of cellulose 0.05%-0.1%, lignocellulose 0.3%-0.7%, hydrophober 0.05%-0.1% stir after mixing and make.
