Abstract
The invention discloses a citric acid gypsum hollow block and its preparation method. The citric acid gypsum hollow block comprises the following raw materials by weight: 59-69.95 parts of citric acid gypsum powder (beta type); 20-25 parts of desulfurized gypsum powder (beta type); 2-3 parts of a reinforcing agent; 8-12 parts of a neutralizer; and 0.05-1 part of a water reducer. The hollow block provided in the invention has an excellent color better (whiter than ordinary gypsum hollow blocks), is more conducive to wall decoration, and has the effects of light weight, waterproofness as well as thermal insulation. With all indexes meeting the JC/T698-2010 and GB6566-2001 building materials radionuclide limited standards of gypsum blocks, the hollow block is also in line with the requirements of low carbon, environmental protection, energy saving and consumption reduction, and recycling economy, and alleviates the environmental pollution problem to certain extent.
Description
Technical field:
The present invention relates generally to a kind of gypsum hollow block, relates in particular to a kind of citric acid gypsum holllow building block and preparation method thereof.
Background technology:
Gypsum hollow block generally is the novel internal partition wall materials for wall that utilizes plaster of Paris to produce, because low, the lightweight of its cost, waterproof, and meet low-carbon (LC), environmental protection, energy-saving and cost-reducing, make simple, high insulating effect, the advantage such as sturdy and durable is widely used in the buildings internal partition wall, so create a kind of dominant direction of utilizing new trade waste to become the gypsum hollow block development as main raw material.
Main raw material citric acid gypsum among the present invention, be produce when utilizing dull method to produce citric acid take terra alba as main industrial residue: citric acid gypsum.1 ton of citric acid of every production can obtain 1.5 tons of citric acid gypsums; Citric acid gypsum makes the semi-hydrated gypsum low strength of producing owing to contain certain remaining acid and organism (mycelium), and time of coagulation is elongated, utilizes difficulty; Can not get for a long time effectively utilizing and bulk deposition to environment.
Summary of the invention:
For solving an above-mentioned difficult problem, the invention provides a kind of citric acid gypsum holllow building block and preparation method thereof, it is main raw material that the contriver utilizes citric acid gypsum powder (β type) and other trade wastes, make in conjunction with other auxiliary materials, and in conjunction with new manufacture craft, so that the citric acid gypsum holllow building block that this prescription is produced is with lightweight, waterproof, the advantages such as insulation, and its indices all meets gypsum block JC/T698-2010 and the requirement of GB6566-2001 radioactive material nucleic limit standard, also meets in addition low-carbon (LC), environmental protection, energy-saving and cost-reducing, the requirement of recycling economy.
Technical scheme of the present invention is as follows:
A kind of citric acid gypsum holllow building block, raw material and weight part are:
Citric acid gypsum powder (β type): 59-69.95 part;
Desulfurization gypsum powder (β type): 20-25 part;
Toughener: 2-3 part;
Neutralizing agent: 8-12 part;
Water reducer: 0.05-1 part;
Ratio of water to material: 0.73-0.76 part.
Described toughener is blast furnace water quenching ore deposit quarrel powder, and described neutralizing agent is unslaked lime, and described water reducer is trimeric cyanamide.
Raw material and weight are preferably:
Citric acid gypsum powder (β type): 63-69.95 part;
Desulfurization gypsum powder (β type): 20-23 part;
Toughener: 2-3 part;
Neutralizing agent: 9-11 part;
Water reducer: 0.06-1 part;
Ratio of water to material: 0.74-0.76 part.
Its making step is as follows:
(1) batching: each raw material is prepared in proportion by self-measuring device;
(2) mass transport: each raw material is arrived the appointment storage tank by the e Foerderanlage automatic transport respectively;
(3) stir: designated ratio water is added first mixing drum, open stirrer, add the designated ratio retardant, again unclassified stores is dropped into mixing drum, stirred about 30 seconds;
(4) moulding: the slip after will stirring injects cavity forming, can obtain work in-process after about about 15 minutes, by mechanical manipulator work in-process is moved on the transport trolley platform again;
(5) piling, maintenance: piling (or the rear piling of oven dry) is carried out in the building block of work in-process citric acid gypsum, and natural curing, the maintenance fate is about 28 days;
(6) total inspection, warehouse-in.
The present invention is because its main raw material is citric acid gypsum powder etc., institute is so that product has: color and luster excellent (all whiter than common gypsum holllow building block), more be conducive to the powdering of body of wall, and the effect with lightweight, waterproof, insulation, and indices of the present invention all meets gypsum block JC/T698-2010 and the requirement of GB6566-2001 radioactive material nucleic limit standard; And meet the requirement of low-carbon (LC), environmental protection, energy-saving and cost-reducing, recycling economy, and alleviated to a certain extent problem of environmental pollution.
