In addition, as the solid wastes are utilized in the color inorganic facing mortar, the cost of the inorganic facing mortar is reduced, and the market competitiveness of inorganic facing mortar products is increased.

Description

A kind of solid waste toning blue inorganic facing mortar and preparation method thereof
Technical field
The invention belongs to building materials field, relate to a kind of solid waste toning blue inorganic facing mortar and preparation method.
Background technology
Along with socio-economic development, electroplating industry is development also, and the pollution problem of electroplating wastewater is on the rise.Tradition, chemical precipitation method is the method for the most frequently used these waste liquids of processing.Oxyhydroxide and sulfide are the most frequently used reagent, and wherein hydroxide precipitation method is the most conventional, are as NaOH, NaCO by alkaline matter 3, Ca (OH) 2and Mg (OH) 2or the mixture of these materials joins in waste liquid, make heavy metal precipitation and remove.
But this method has a maximum shortcoming, can produce exactly a large amount of electroplating sludges, although the total amount of electroplating sludge is more much smaller than waste water, but because heavy metal is all transferred in mud with precipitation, therefore, say in a sense, the harm of electroplating sludge is also larger than the harm of waste water.In " national Hazardous Waste List ", electroplating sludge has occupied 7 large classes wherein, and undressed electroplating sludge, can cause the pollution of soil and water body, the harm people's that heavy metal ion wherein and compound can be direct or indirect health.Therefore, should take reasonable measure and reclaim the useful heavy metal in electroplating sludge, reduce the harm to environment.
Electroplating sludge composition is extremely complicated, initial basic treatment process comprises stacking, landfill, burn, fill out sea and lagoon etc., apparent these preliminary treatments very likely can cause secondary pollution, some recycling means were developed again afterwards, in electroplating sludge comprehensive treating process, aspect turns waste into wealth, domestic and international many units do a lot of work, although many methods are from effect, in adaptability and economic benefit, see progressive to some extent, but up to the present, the way that there is no a kind of comparative maturity and can thoroughly deal with problems, therefore a kind of cost-effective processing recovery method is necessary very much.Blue nickeliferous comprehensive mud is as a kind of electroplating sludge, and the comprehensive Utilization Ways of seeking its resource utilization is also very urgent.
Colored finish mortar is a kind of novel inorganic powder shape finishing material, and the inner, external wall that extensively replaces coating and ceramic tile to be applied to buildings in developed country is decorated.Polychromy mortar is using polymer materials as main additive, is equipped with that high-quality mineral aggregate, filler and natural mineral pigment are refining to be formed.Coat-thickness is generally between 1.5~2.5 millimeters, and generic latex paint lacquer painting thickness is only 0.1 millimeter, therefore can obtain fabulous texture and three-dimensional decorative effect.In addition, colored finish mortar product also has the following advantages:
1, material has gently solved the buildings problem of gaining in weight;
2, the flexible moulding that is applicable to circle, cylinder and arc;
3, shape, size, color can customize by user's requirement;
4, color is simple and unsophisticated ornamental strong;
5, construct simple good endurance and substrate has very strong cohesive force;
6, waterproof, impervious, ventilative, anti-contraction;
7, nonpoisonous and tasteless, green structural material.
When construction, by the different gimmicks such as select template, the instrument of different graphic, impose to drag, roll, scrape, turn round pressure, rub, metope is changed and the various patterns such as embossing, ripple, wood grain, artistic expression is strong, can more ideally merge with physical environment, architectural style and historical sites.
Therefore, in recent years, colored finish mortar has obtained comparatively widely application at home, and along with the further excavation of its advantage, its application in building structure facing will be more extensive.But due to the use of organism and mineral pigment in colored finish mortar, cost is higher.Therefore, searching can be stablized toning and the relatively low component of price becomes and produces a key areas of colored mortar.
Due to the feature of nickeliferous electroplating sludge color in electroplating sludge, and be solid waste because of it, and cement can solidify the dangerous component in electroplating sludge, therefore, the nickeliferous comprehensive electroplating sludge powder that application mummification is broken up is mixed colours, the blue inorganic mortar of producing a kind of solid waste toning is that one both can solve solid waste recycling, can reduce again the approach of inorganic color mortar cost.
Summary of the invention
The object of the present invention is to provide inorganic blue facing mortar of a kind of solid waste toning and preparation method thereof.
The inorganic blue mortar of solid waste toning that the present invention proposes, the nickeliferous comprehensive mud powder of industrial Electroplate Factory, white cement, quartz sand, rubber powder, solid polycarboxylic acid water reducing agent, ether of cellulose and starch ethers that described mortar raw material is broken up by mummification form, and the mass percent of raw material composition is:
The nickeliferous comprehensive mud powder 1wt%~5wt% of industrial Electroplate Factory that mummification is broken up
White cement 22.5wt%~24.5wt%
Quartz sand 67.5wt%~73.5wt%
Rubber powder 1wt%~3wt%
Solid polycarboxylic acid water reducing agent 0.2wt%~2.5wt%
Ether of cellulose 0.02wt%~0.1wt%
Starch ethers 0.006wt%~0.03wt%,
Its gross weight meets 100%.
In the present invention, described solid waste is mixed colours, and to apply thickness be 1.5~2.5mm to inorganic purple mortar.
The mix colours preparation method of inorganic purple mortar of the solid waste that the present invention proposes, concrete steps are: the nickeliferous comprehensive mud powder of industrial Electroplate Factory, white cement, quartz sand, rubber powder, solid polycarboxylic acid water reducing agent, ether of cellulose and the starch ethers mummification broken up by proportioning raw materials, in any homogenizer tool, carry out homogenizing, obtain desired product.
In the present invention, the nickeliferous electroplating integrated mud that mummification is broken up is mainly as toning component, white cement is mainly as bonding component, rubber powder is mainly used in improving the cohesive strength of mortar, and solid polycarboxylic acid water reducing agent is mainly used in improving the mobility of mortar, improves the operability of mortar, ether of cellulose and starch ethers are for adjusting the viscosity of mortar, improve the operability of mortar, quartz sand is for aggregate, for mortar lifting is for structural framework.Production blue inorganic facing mortar of the present invention, can solve the recycling problem of Electroplate Factory's nickel-containing sludge solid waste, and can reduce the production cost of inorganic color mortar.
Product toning prepared by the present invention and the approach of solid waste recycling are: the color characteristic of the nickeliferous electroplating integrated mud powder that employing mummification is broken up is adjusted the color and luster of inorganic facing mortar, application by the nickeliferous electroplating integrated mud broken up in inorganic color mortar, solves the recycling problem of harmful solid waste.
