Abstract
The present invention discloses a method for preparing splitting tiles by using Taihu silt. The method comprises: adding feldspar, kaolin, quartz, mica, a dry mixing agent and water to dried particles of a Taihu silt raw material, mixing and uniformly stirring, and then sequentially carrying out extruding forming, drying, and calcination to prepare the splitting tiles. According to the present invention, the difficulty of Taihu silt treatment can be solved from the source; with high temperature calcination, the problem of heavy metals, pathogens and organic pollutants in the Taihu silt is thoroughly solved so as to achieve regeneration resource utilization of the silt, and avoid secondary pollution generation; and the produced splitting tiles have characteristics of excellent flexural strength, anti-erosion property and the like, and do not produce secondary pollution after high temperature calcination, such that a large amount of land occupation required by landfill can be saved, and requirements of environmental protection and comprehensive utilization of resources in our country are met.
Description
Technical field
The invention belongs to environment protection and utilization of resources field, be specifically related to a kind of method of utilizing Taihu Lake mud to prepare the brick of riving.
Background technology
Contain a large amount of mikrobes, pathogenic agent, heavy metal and organic pollutant in the mud of current Taihu Lake, be not good to cause the secondary severe contamination, particularly get into season in midsummer like processing; Along with the rising of temperature, have a large amount of blue-green algaes in the TAIHU LAKE and produce, find but from the production process of blue-green algae, analyze; It not only has relation with water quality temperature, and with Taihu Lake in a large amount of mud of existing confidential relation is arranged, present water conservancy at different levels environmental administration every year, the mud to Taihu Lake went out later disposal clearly; Main means still be landfill and burning disposal be main, contain a large amount of organism and heavy metal owing in the mud, like the employing landfill; Then can bring great harm to soil, because the mud water ratio is higher, mechanical property is poor simultaneously; Not only take the landfill place, often can also cause secondary pollution.As adopt burning disposal, and then investment and running cost are all higher, and particularly energy consumption is bigger, also exists the problem of the off gas treatment when burning simultaneously.Therefore, properly settling the problem of utilizing of Taihu Lake mud, become the task of top priority, also is effectively to solve Taihu Lake water quality, prevents the important topic that blue-green algae grows.
Summary of the invention
There is technical deficiency at present in the disposal that the present invention is primarily aimed at Taihu Lake mud, provides that a kind of cost is low, effective, applied widely, a kind of Taihu Lake mud preparation brick method of riving of utilizing of non-secondary pollution.
The object of the invention can reach requirements of making through following technology:
A kind of method of utilizing Taihu Lake mud to prepare the brick of riving: with the dry material of raw material Taihu Lake mud, add feldspar, kaolin, quartz, mica, the even stirring of dried mixture and water mixing back,, make after the calcining again through carrying out drying behind the extrusion under vacuum; Wherein the mass ratio of each raw material does, the dry material of Taihu Lake mud, feldspar, kaolin, quartz, mica, dried mixture: water=10～50:15～40:8～30:3～6:2～5:1～5:3～8.
The preferred mass ratio of above-mentioned each raw material is: the dry material of Taihu Lake mud, feldspar, kaolin, quartz, mica, dried mixture: water=20～40:30～40:15～30:4～6:2～5:1～4:5～8.
A mud dry material in Taihu Lake is formed by Taihu Lake mud drying and crushing, and its water ratio is 20%～40%.In the dry material of Taihu Lake mud, also can add pigment or other raw materials, make the brick of processing of riving have special color, like dim redness etc.
Above-mentioned felspathic median size is 16～32mm.
Described dried mixture adopts interfacial agents or sticker.
In adopting extrusion molding, the pressure of selecting extrusion molding for use is 10～20Mpa, and the forming pressure hold-time is no less than 3 seconds.
In drying process, the temperature of selecting for use is 110～130 ℃, with 120 ℃ be the best, be 2～5 hours its time of drying.
Generally speaking, after extrusion molding and before the drying, need place 1～3 hour preferred 2～4 hours under field conditions (factors).
In calcination process, temperature is controlled to be 1106～1180 ℃, and calcination time was generally 5～11 hours.
The average shrinkage ratio of the brick of riving that present method makes is 3.8～5.2%, folding strength average out to 22.4～29.5MPa, and frost resistance-28～+ 32c; Aberration 0.16～0.2%; 8.5～10.5 grades of shock resistance earthquake intensitys, shock resistance 0.75～0.8MPa, average water-intake rate is between 7.5～8.3%.Ultimate compression strength average out to 15.5～21.8.MPa.The size of brick of riving can be adjusted as required, as adopting specification sizes such as 260*66*30mm commonly used.
The present invention utilizes Taihu Lake mud and adds other raw material production brick of riving; Can realize the lifting of Taihu Lake water quality; Also can realize the innoxious and comprehensive utilization of resources of Taihu Lake mud, it is turned waste into wealth, the brick of producing of riving can satisfy building outer wall decorative material, park; The request for utilization of gardens, square, dwelling house garden again can be as the carrier of building type material.
The present invention can solve the difficult problem that the Taihu Lake sludge treatment is disposed from the source, thoroughly solved the problem of heavy metal, pathogenic agent and organic pollutant in the mud of Taihu Lake, has realized the renewable resource utilization of mud, has avoided the generation of secondary pollution.The brick of being produced of riving not only has characteristics such as folding strength is good, scour resistance is good; And produced rive brick after high-temperature calcination, can not produce secondary pollution, can practice thrift the required soil that takies of a large amount of landfills; Also can effectively avoid the exhaust emission environmental problem that adopts burning to bring; Combine present China carrying out promoting the use of of environmental renovation and building outer wall decorative material simultaneously,, meet China environmental protection comprehensive utilization of resources requirement from resource circulation utilization; This brick of riving relatively is suitable for building outer wall decorative material and park, gardens, square, dwelling house garden and afforestation ecological engineering.
