Description
Technical field
The present invention relates to building material technical field, relate in particular to a kind of method of utilizing polishing slag to manufacture haydite water-permeable brick.
Background technology
Polishing slag is mainly to produce in the process of grinding in ceramic tile, polishing, and its composition is mainly silicon carbide, magnesium oxide, magnesium chloride and the brick bits etc. in grinding head for polishing.According to statistics, the quantum of output of annual China polished tile polishing slag is up to 700～8,000,000 tons, and presents the trend of cumulative year after year.The ceramic tile of utilizing polishing slag to make for raw material easily produces foaming and problem on deformation in burning till, and limits it and recycles production wall floor tile, and most of ceramics factory adopts land-fill method to process polishing slag.And the landfill of polishing slag, not only labor intensive and material resources, also can polluted underground water matter.More there are some ceramics factories privately to topple over polishing slag in violation of rules and regulations, cause very rugged environment to pollute and social influence.Therefore, how to turn waste into wealth, make full use of polishing slag and produce environment-friendly and green ceramic, the polishing slag of can not only effectively dissolving, protection of the environment, also meets the requirement that the current Chinese government sets up conservation-minded society and recycling economy.
The water-permeable brick of seeing on domestic and international market at present can be divided into two classes from material and production technique, and a class is by mixed clays such as building waste, industrial wastes, and the water-permeable brick forming by pulverizing, moulding, high-temperature firing, is called ceramic water-permeable brick; Another kind of is to take ceramic as main raw material, adds organic, inorganic adhesive, makes, due to need not sintering, so be called baking-free water-permeable brick by moulding, curing process.
In the prior art, in order to make water-permeable brick there is a certain amount of through hole, improve coefficient of permeability, often by controlling the particle diameter of aggregate or adding in admixtion that pore-forming material realizes.Existing water-permeable brick aggregate used mostly is the broken kernel of the broken particle processed of lithotome or useless burned product, and these particles have sharp-pointed corner angle mostly, and these wedge angles very easily cause the injury of people, car, reduces water-permeable brick intensity, also affects permeable effect.In addition, CN102417332A discloses a kind of method of utilizing lake sludge to manufacture steam pressure water-permeable brick, it is characterized in that: 1) manufacture foamed ceramic ball; 2) foamed ceramic ball classification; 3) preparation water-permeable brick basic unit blank; 4) preparation chromatograph blank; 5) digestion; 6) rolling; 7) secondary material distributing; 8) steam press maintenance.The easy losing angle of water-permeable brick that the method prepares, and intensity not high (ultimate compression strength is 40MPa).Also have CN103553448A to disclose a kind of haydite water-permeable brick and preparation method thereof, it is characterized in that the haydite that silica sand dust is produced produces haydite water-permeable brick in conjunction with a small amount of cement, setting accelerator, water reducer and silica sand fabric, this water-permeable brick, with haydite, replace stone, outward appearance is beautiful on the one hand, combines on the other hand the high-strength feature of this haydite light weight.The water-permeable brick that the method prepares does not fully take into account the combination of different-grain diameter spherical haydite, easily causes the closestpacking of large particle diameter and small particle size haydite, has a strong impact on permeable effect (coefficient of permeability (15 ℃) is 0.05cm/s).
