Abstract
The invention relates to a construction desulfurizing gypsum coating material, which comprises desulfurizing construction gypsum 90-99.8 wt%, hydraulic cementing material 0-9.8 wt%, set retarder 0.1-0.5 wt% and water-loss reducer 0.1-0.3 wt%.
Description
Technical field
The present invention relates to a kind of plastering material for building, particularly desulfurization gypsum plastering material.
Background technology
Whitewash engineering and be the important component part in the construction work.Gypsum plastering material has fast solidifying, light weight, exquisiteness, cohesive strength height, and the hollowing that do not ftracture, characteristics such as fire resistance is good are a kind of novel plastering materials of superior performance, are subject to people's attention gradually.Up to now, mainly concentrate on, as application for a patent for invention number 02136118.5 and 02111055.7 with the separately preparation or mix the manufacturing plastering material with semi-hydrated gypsum of natural semi-hydrated gypsum by the dehydrated gyp-that dihydrate gypsum is sintered into.
Along with the attention to environmental protection, China comes into effect the power plant desulfurization technology the early 1990s.In order to reduce power plant emission solid waste landed property, it is imperative to make good use of desulfurated plaster.The exploitation desulfurization gypsum plastering material is one of effective way of utilizing desulfurated plaster, and the plastering material that can be construction industry simultaneously adds new kind, reduces the gypsum plastering material cost.
Summary of the invention
The object of the present invention is to provide a kind of high strength, the desulfurization gypsum plastering material of low material cost.
To achieve these goals, technical solution of the present invention is: a kind of desulfurization gypsum plastering material, it comprises desulphurization building gypsum, hydraulicity cement, retardant and water-holding agent.The per-cent of the shared desulfurization gypsum plastering material gross weight of each component is:
Desulphurization building gypsum 90～99.8 hydraulicity cements 0～9.8
Retardant 0.1～0.5 water-holding agent 0.1～0.3.
The present invention is that employing power plant desulfurization lime-ash is that raw material prepares desulfurization gypsum plastering material, its objective is the solid waste of utilizing power plant emission, reduce the soil that solid waste takies, reduce environmental pollution, can be construction industry simultaneously a kind of lower-cost novel plastering material is provided.
Embodiment
The used hydraulicity cement of the present invention comprises: cement, flyash or their mixture.
The used retardant of the present invention comprises: citric acid, tartrate, Trisodium Citrate, sodium phosphate, SODIUM PHOSPHATE, MONOBASIC or their mixture.
The used water-holding agent of the present invention comprises: methylcellulose gum, Vltra tears, hydroxyethylmethyl-cellulose, treated starch or their mixture.
Make the bottom desulfurization gypsum plastering material as adding in the above-mentioned mixture less than the medium sand of 5mm, the addition of medium sand is 1～2 times of above-mentioned compound.
The present invention is that employing power plant desulfurization lime-ash is that raw material prepares desulfurization gypsum plastering material, its objective is the solid waste of utilizing power plant emission, reduce the soil that solid waste takies, reduce environmental pollution, can be construction industry simultaneously a kind of lower-cost novel plastering material is provided.
