Abstract
The invention discloses a haydite and a preparation method thereof. The haydite is characterized by comprising the following components in percentage by weight: 40-100% of ceramic factory waste tail mud, 0-40% of bentonite and 0-50% of water treatment sludge. The preparation method comprises the following steps: 1) crushing the raw materials, mixing, and evenly stirring to obtain a composite semi-finished earth material; naturally drying or baking the semi-finished earth material until the water content is 15-25%, and granulating in a granulator; and 2) firing the granules in a rotary kiln while adjusting the rotation speed of the kiln and the supply amount of fuel according to the firing effect, thereby obtaining the 5-30mm continuous grading haydite. In order to overcome the defects in the prior art, the invention provides an environment-friendly haydite capable of substituting clay as a raw material. The invention also aims to provide a preparation method of the haydite.
Description
Technical field
The present invention relates to a kind of haydite, the invention still further relates to a kind of method for preparing this haydite.
Background technology
In recent years, the wall of China changed policy and deepened continuously, and implementation dynamics is strengthened gradually, had built a great market space for thus the development of building material.Haydite is as a kind of light skeletal for building, received people's very big attention with characteristics such as its light body, insulation, sharp useless, environmental protection.With it is the new high-tech product that the light aggregate concrete hollow paving block processed of raw material, beam, plate etc. have become China's development novel wall material.
The traditional raw material of producing haydite mainly contains shale, clay etc.The performance index of its production technique of different material and products thereof also have nothing in common with each other.In general, the expansion ratio of clay is bigger, the little good heat insulating of the unit weight of product, but cylindrical compress strength is lower relatively, can be used for production non-bearing holllow building block product.Raw materials such as shale can be produced heavy body haydite, are used to produce bearing building block, beam, plate etc.
Clay source mainly is to plough and mountain soil, and in recent years, owing to receive the restriction of land resources, leca has been under an embargo in certain areas and has produced and use.
Other equivalent material that later stage occurs such as flyash, riverway sludge etc. particularly aspect the contradictory relation of unit weight and intensity, all fail to reach the effect consistent with leca in product performance.Seeking a kind of more environmental protection, high performance clay equivalent material is the emphasis of ceramic particle technology development from now on.
Summary of the invention
The objective of the invention is provides a kind of environmental protection in order to overcome weak point of the prior art, and alternative clay is the haydite of raw material.
Another object of the present invention provides a kind of method for preparing above-mentioned haydite.
In order to achieve the above object, the present invention adopts following scheme:
A kind of haydite is characterized in that being processed by following component by weight percentage:

Haydite of the present invention can adopt the discarded tail mud of ceramics factory arbitrarily; Wilkinite and water treatment sludge; And the discarded tail mud of the ceramics factory that is adopted in the embodiment of the invention is purchased the ceramic industry garden, Jin Li town, Zhaoqing Gaoyao City in Guangdong Province, is the general discarded tailing of Production of Ceramics producer; Water treatment sludge is purchased the sewage work in the Yangjiang City Yangxi, is the water treatment procedure waste products.
Aforesaid a kind of haydite is characterized in that being processed by following component by weight percentage:
Ceramics factory discards tail mud 40～80%
Wilkinite 5～35%
Water treatment sludge 1～45%.
A kind of preparation of the present invention is the method for haydite as stated, it is characterized in that may further comprise the steps:
A, will mix behind the raw material crushing, stir, make compound work in-process earth material; With work in-process earth material natural drying or oven dry, make its water ratio remain on 15-25%, get into nodulizer and granulate;
2) granulation gained particle is sent in the rotary kiln fired, regulating the kiln rotating speed is that little kiln per minute 3-5 changes, Dayao per minute 2-4 changes; Coal confession amount 3-5 lattice, burn the haydite of 5-30mm continuous grading.
Raw material described in the present invention can also be earlier carries out fragmentation mixing after the drying treatment through airing etc. in advance again;
Haydite prescription of the present invention is reasonable, and the loose accumulation unit weight of ceramic product of the present invention is 300～800kg/m
3, the haydite of polytype continuous grading of cylindrical compress strength 2～10MPa satisfies the technical requirements of different demands.
In sum, beneficial effect of the present invention:
One, haydite of the present invention forms through high-temperature firing, has good thermostability, as light skeletal, can improve the whole value of expanding with heat and contract with cold of concrete effectively;
Two, the raw material of haydite use of the present invention is harmless after high temperature process, does not have radiological hazard, does not have toxic volatile gas to produce, and is applicable to building structure.
Three, the present invention has at utmost utilized industrial waste, and economic environmental protection does not contain waste in the final product, be a kind of material of construction of very environmental protection.
