Abstract
The invention discloses an ammonia stabilizer for concrete. The raw material formula of the ammonia stabilizer comprises the following raw materials: 5%-8% of triethanolamine, 5%-8% of silver nitrate, 35%-40% of zinc nitrate and 44%-60% of water. The silver ions of silver nitrate, zinc ions of zinc nitrate and ammonium ions in the raw material formula disclosed by the invention have strong complexing action to generate a silver-ammonium complex and a zinc-ammonium complex. These complexes can stably exist under a strong alkaline condition, so that the ammonium stably exists in the concrete and cannot be released outwards. The powder material is fully dispersed due to the triethanolamine, so that the ammonium ions are fully complexed with the silver ions and the zinc ions, and the stabilization effect of the ammonia stabilizer is ensured.
Description
Technical field
The present invention relates to a kind of for concrete ammonia stablizer, belong to the reinforcement of concrete auxiliary agent technical field.
Background technology
Along with the continuous increase of Environmental protection attention degree; oxynitride has become the priority control target of country; each high-power station denitration project starts one after another, and some denitrating technique has excess ammonia and produces in denitrification process, and these ammonia finally can be cured in flyash.These flyash are in the process of concrete-agitating, the ammonia be solidificated in wherein will discharge, give out pungent smell, huge threat is produced to the health of workmen and buildings user of service, in addition, excess ammonia discharges, and causes bubble in concrete to produce in a large number, concrete intensity is significantly declined, has had influence on the structural safety of whole buildings.
Except flyash, in order to the activity of excited cementing material, also add urea etc. in a lot of grinding aid and contain Ammonia material; The poly carboxylic acid synthesis initiator of some producer can use ammonium persulphate; Also containing Ammonia material in some concrete antifreezer, these materials all can encounter the same problems of ammonia release when concrete construction.Publication number is the patent of invention of CN103353441, discloses the measuring method of ammonia eduction rate in a kind of concrete sample, but, not yet there is the technical scheme solving ammonia release in concrete.
Summary of the invention
The object of the invention is to provide a kind of for concrete ammonia stablizer.
For achieving the above object, the technical solution used in the present invention is: a kind of for concrete ammonia stablizer, the composition of raw materials of described ammonia stablizer comprises the material of following masses percentage composition;
Trolamine 5 ~ 8%;
Silver Nitrate 5 ~ 8%;
Zinc nitrate 35 ~ 40%;
Water 44 ~ 60%.
Preferred technical scheme is: the purity of described trolamine is more than or equal to 99%.
Preferred technical scheme is: described acid silver and zinc nitrate are analytical pure.
Because technique scheme is used, the present invention compared with prior art has following advantages and effect:
Silver ions in Silver Nitrate in composition of raw materials of the present invention, the zine ion of zinc nitrate and ammonium radical ion have powerful complexing action and generate silver-colored ammonium complex compound and zinc ammonium complex, and these complex compounds can stable existence under strongly alkaline conditions.Thus ammonia can stably be present in concrete, can not outwards discharge.Trolamine makes powder body material fully disperse, and makes ammonium ion fully and silver ions and zine ion complexing, ensure that the stabilization of this ammonium stablizer.
Embodiment

A kind of for concrete ammonia stablizer, the composition of raw materials of described ammonia stablizer comprises the material of following masses percentage composition;
Trolamine 8%;
Silver Nitrate 5%;
Zinc nitrate 35%;
Water 52%.
Embodiment three: a kind of for concrete ammonia stablizer
A kind of for concrete ammonia stablizer, the composition of raw materials of described ammonia stablizer comprises the material of following masses percentage composition;
Trolamine 5%;
Silver Nitrate 7%;
Zinc nitrate 40%;
Water 48%.
The purity of described trolamine is 99.1%.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to spirit of the present invention change or modify, and all should be encompassed within protection scope of the present invention.
