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 ammonia stabilizer for concrete, belong to concrete used additives technical field.
Background technology
Protect being continuously increased of attention degree with Environmental, nitrogen oxides has become the priority control mesh of country
Mark, each high-power station denitration project starts one after another, and some denitrating techniques have excess ammonia in denitrification process and produce, and these ammonia are last
Can be cured in flyash.During concrete-agitating, being solidificated in ammonia therein will discharge these flyash, dissipate
Give out a pungent smell, huge threat is produced to the health of workmen and building user of service, additionally, excess ammonia is released
Put, lead to bubble in concrete to produce in a large number, so that the intensity of concrete is significantly declined, had influence on the structure of whole building thing
Safety.
In addition to flyash, for the activity of excited cementing material, also add urea etc. in a lot of grinding aids and contain ammonia
Class material；The polycarboxylic acids synthesis initiator of some producers can use ammonium persulfate；Also Ammonia is contained in some concrete antifreezers
Material, these materials all can encounter the same problems of ammonia release in concrete construction.The invention of Publication No. cn103353441
Patent, discloses a kind of assay method of ammonia eduction rate in concrete sample, but, not yet have and solve ammonia release in concrete
Technical scheme.
Content of the invention
It is an object of the present invention to provide a kind of ammonia stabilizer for concrete.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of ammonia stabilizer for concrete, described ammonia
The composition of raw materials of stabilizer comprises the material of following masses percentage composition；
Triethanolamine 5～8%；
Silver nitrate 5～8%；
Zinc nitrate 35～40%；
Water 44～60%.
Preferably technical scheme is: the purity of described triethanolamine is more than or equal to 99%.
Preferably technical scheme is: it is pure that described acid silver and zinc nitrate are analysis.
Because technique scheme is used, the present invention compared with prior art has following advantages and an effect:
The silver ion in silver nitrate in the composition of raw materials of the present invention, the zinc ion of zinc nitrate and ammonium ion have powerful
Complexing generate silver-colored ammonium complex compound and zinc ammonium complex, these complex compounds can stable existence under strongly alkaline conditions.Thus
Ammonia can stably be present in concrete, will not outwards discharge.Triethanolamine makes powder body material fully dispersed so that ammonium ion fills
Point it is complexed it is ensured that the stabilization of this ammonium stabilizer with silver ion and zinc ion.
Specific embodiment
With reference to embodiment, the invention will be further described:
A kind of embodiment one: ammonia stabilizer for concrete
A kind of ammonia stabilizer for concrete, the composition of raw materials of described ammonia stabilizer comprises following masses percentage composition
Material；
Triethanolamine 5%；
Silver nitrate 5%；
Zinc nitrate 40%；
Water 50%.
The purity of described triethanolamine is 99%.
It is pure that described acid silver and zinc nitrate are analysis.Water is running water.When using, each material is claimed according to composition of raw materials
After amount is good, pours in a container, be stirring evenly and then adding in the raw material of concrete.Before adding the raw material of concrete, first really
Determine the ammonia content of each part of concrete material, the patent of invention of Publication No. cn103353441 can be adopted, disclosed
The assay method of ammonia eduction rate, or directly adopt the ammonia content in chemical gauging concrete.Then stable further according to ammonia
The effective content of the silver nitrate of agent and zinc nitrate is determining the addition of ammonia stabilizer it is to be ensured that the content of silver ion and zinc ion
More than the content of ammonia, so just can ensure that the ammonia in concrete is fixed because of whole generation complex compounds.
A kind of embodiment two: ammonia stabilizer for concrete
A kind of ammonia stabilizer for concrete, the composition of raw materials of described ammonia stabilizer comprises following masses percentage composition
Material；
Triethanolamine 8%；
Silver nitrate 5%；
Zinc nitrate 35%；
Water 52%.
A kind of embodiment three: ammonia stabilizer for concrete
A kind of ammonia stabilizer for concrete, the composition of raw materials of described ammonia stabilizer comprises following masses percentage composition
Material；
Triethanolamine 5%；
Silver nitrate 7%；
Zinc nitrate 40%；
Water 48%.
The purity of described triethanolamine is 99.1%.
Above-described embodiment only technology design to illustrate the invention and feature, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and implements according to this, can not be limited the scope of the invention with this.All according to the present invention
Equivalence changes or modification that Spirit Essence is made, all should be included within the scope of the present invention.
