Description

A kind of building decoration engineering ardealite based self-leveling material
Technical field
The invention belongs to building intellectualization installing engineering technical fields, and in particular to a kind of building decoration engineering building dress Adorn engineering ardealite based self-leveling material.
Background technique
Ardealite is that wet process manufactures the waste residue being discharged when phosphoric acid in phosphorous chemical industry, and 1 ton of phosphoric acid of every production is (with P2O5Meter) it generates about 4.5~5.5 tons of by-product ardealite, about 80,000,000 tons of China's ardealite yield in 2015, while there is also about 2.5 hundred million in China The ardealite history stockpiling of ton.The accumulation not only land occupation, but also waste of resource of a large amount of ardealite, wherein the acidity that contains and its His harmful substance is easy to pollute surrounding enviroment, endangers ecological environment.Leaching Properties of Soluble Phosphorus, fluorine, organic matter in ardealite etc. are miscellaneous Matter is made the building gypsum plaster prepared using ardealite the adverse consequences such as setting time is long, intensity is low occur, seriously restricts phosphorus stone The extensive application of cream.The improvement of ardealite and Utilizing question are a global problems.Many phosphate fertilizer producers bear heavy thus Weight, ardealite problem have become the world-famous puzzle of the sustainable development of relationship phosphorous chemical industry and environmental protection.
Main component in ardealite is calcium sulphate dihydrate, production gypsum base building materials be now efficiently use in fact it is main Approach.Self-leveling material is one kind using cementitious material as base-material, and various additives modifications are added is used for the novel of floor leveling Earth material.Chinese patent CN102643065A discloses a kind of ardealite self-leveling material, changes in the invention self-leveling material Property ardealite has only accounted for 30%.
Summary of the invention
The purpose of the present invention is to provide a kind of ardealite dosage be more than 50% building decoration engineering with ardealite base from Levelling material reduces land seizure caused by due to ardealite discharge and the problem of environmental pollution.
In order to achieve the above objectives, the present invention uses following technical scheme, a kind of building decoration engineering ardealite base gravity flow Flat material, weight percentage of each component are as follows:
Modified ardealite: 50%-60%
Cement: 10%-15%
