Abstract
The invention relates to a method for preparation of a thermal insulation wall material from river sludge. The method comprises the technological steps of: 1) storing the river sludge to a moisture content of 30%-40%; 2) adding vitrified microspheres or perlite, and conducting stirring to uniform, then performing standing; 3) making the material into billets of various shapes and sizes; and 4) conducting drying, then sending the billets into a kiln to undergo firing, thus finally forming the thermal insulation wall material. The method for preparation of the thermal insulation wall material from river sludge provided by the invention has the advantages of simple process, low cost, sufficient utilization of waste, environmental pollution reduction and the like. And the prepared thermal insulation wall material has the characteristics of good thermal insulation effect, hard cracking and the like.
Description
Technical field
The present invention relates to a kind of preparation method of insulating wall material, be specifically related to the method that a kind of river course mud is prepared insulating wall material.
Background technology
River regulation is the important means of beautifying the environment, and still, in cleaning river course process, conventionally can produce a large amount of river course mud.In river course mud, contain the nutritive substances such as a large amount of organism and abundant nitrogen, phosphorus, also exist the hazardous and noxious substances such as heavy metal, pathogenic bacterium and parasite.How river course mud is processed and become a difficult problem.
At present, to the processing of river course mud, be mainly mud is dug out and carry out landfill or accumulation, so not only waste time and energy, and easily cause secondary pollution.In order to make full use of resource, also have in the industry the technology that adopts river course mud to produce lagging material, but the product of producing easily ftractures, second-rate.
Therefore,, for solving the problems of the technologies described above, the necessary method that provides a kind of river course mud to prepare insulating wall material, to overcome described defect of the prior art.
Summary of the invention
For addressing the above problem, the object of the present invention is to provide a kind of cost low, can reduce the method that environmental pollution and river course mud not easy to crack are prepared insulating wall material.
For achieving the above object, the technical scheme that the present invention takes is: a kind of river course mud is prepared the method for insulating wall material, and it comprises following processing step: 1), river course mud is deposited to the water ratio to 30% ~ 40%; 2), add glass bead or perlite, and be stirred to evenly; After stirring, carry out standing; 3), make the blank of different shape size; 4), after oven dry, blank is sent in kiln and fired, finally form insulating wall material.
The method that river course of the present invention mud is prepared insulating wall material is further: the particle diameter of described glass bead is 5 ~ 25 orders or 50-100 order; The add-on of described glass bead is 40% ~ 90% of river course sludge volume.
The method that river course of the present invention mud is prepared insulating wall material is further: when stirring, adopt rotation mixer, its rotating speed is 7 ~ 20r/min, and churning time is 3 ~ 8min; Time of repose is 1 ~ 10 day.
The method that river course of the present invention mud is prepared insulating wall material is further: the temperature of firing in the kiln of described step 4) is 700 ± 50 ℃.
The method that river course of the present invention mud is prepared insulating wall material is further: the intensity of described insulating wall material is MU2.5 ~ 8; Density is 800 ~ 1200kg/m3, and thermal conductivity is 0.1 ~ 0.2.
Compared with prior art, the present invention has following beneficial effect: it is simple that the method that river course of the present invention mud is prepared insulating wall material has technique, cost is low, can make full use of waste material and reduce the plurality of advantages such as environmental pollution, the features such as the insulating wall material making has good effect of heat insulation, not easy to crack.
Embodiment
The present invention is the method that a kind of river course mud is prepared insulating wall material, and it comprises following processing step:
1), river course mud is deposited to the water ratio to 30% ~ 40%;
2), add glass bead or perlite, and be stirred to evenly; Wherein, the particle diameter of described glass bead is 5 ~ 25 orders or 50-100 order, and the glass bead of this particle diameter is discarded glass bead, thereby is conducive to utilization of waste material; The add-on of described glass bead is 40% ~ 90% of river course sludge volume; When stirring, adopt rotation mixer, its rotating speed is 7 ~ 20r/min, churning time is 3 ~ 8min; After stirring, carry out standingly, time of repose is 1 ~ 10 day, and the concrete time is determined according to the result of laboratory test of river course mud;
3), make the blank of different shape size;
4), after oven dry, blank is sent in kiln and fired, finally form insulating wall material; Wherein, the temperature of firing in described kiln is 700 ± 50 ℃; The intensity of the insulating wall material making is MU2.5 ~ 8; Density is 800 ~ 1200kg/m3; Shrinking percentage: nothing; Radioactivity meets GB6566 regulation; Thermal conductivity is 0.1 ~ 0.2; Frost resistance: < 3%; Freeze rear intensity :≤5%.
Wherein, in step 1), also can add vault mud, pile foundation mud, common mud and shale according to the result of laboratory test of river course mud.If the river course sludge quantity adding is few, and the temperature of firing in kiln remains unchanged, and needs to add appropriate coal dust, because river course mud itself has calorific value.
Above embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
