Abstract
The invention discloses a method for manufacturing black microcrystalline glass plates from molybdenum tailings, which comprises the following steps: mixing a certain part by weight of molybdenum tailings, quartz sand, lime stone, sodium carbonate, zinc oxide, barium carbonate, ferric oxide, manganese dioxide, nickel oxide and cobalt oxide to prepare a glass batch; melting the glass batch into molten glass, and then, pouring the molten glass into water to form glass particles; horizontally laying the glass particles in a fire-resistant mold for crystallization heat treatment; and grinding and cutting black microcrystalline glass crude products after crystallization heat treatment to form finished products. By using the molybdenum tailings for manufacturing black microcrystalline glass plates, the invention not only reduces the stockpiling amount of tailings and relieves the environmental pollution, but also can improve the product performance and reduce the production cost, thereby having good social benefit and economic benefit.
Description
Technical field
The present invention relates to a kind of manufacture method of crystallizing glass sheet material, especially relate to a kind of method with manufacturing black microcrystalline glass plates from molybdenum tailings.
Background technology
Devitrified glass is a kind of polycrystalline material that the crystallization by feed glass obtains.Devitrified glass has formed a kind of material of special class at present, and it is various in style, and performance is different, has purposes very widely.Crystallizing glass sheet material is a kind of in the numerous kinds of devitrified glass, it is a kind of novel high-grade building and ornament materials, have the intensity height, resistance to wear, corrosion-resistant, weather resistance, do not absorb water, good physicochemical property and uniform hue such as cleaning convenience, "dead" pollution, gloss is soft sparkling and crystal-clear, and surface compact has no time to wait excellent appearance characteristics.Because the crystallizing glass sheet material various aspects of performance all is better than lithotome, so be widely used in now in all kinds of building decoration engineerings such as building inside and outside wall, ground and corridor post.
Producing the employed raw material of crystallizing glass sheet material at present all is industrial industrial chemicals basically except quartz sand.The shortcoming of this glass batch is: the raw materials cost height, and glass melting temperature height, generally between 1500-1550 ℃, such high temperature will inevitably increase fuel consumption, has aggravated the erosion of glass metal to the kiln refractory materials; Because the industrial chemicals in the glass batch is more, also increased the weight of the erosion of glass metal in addition, influenced service life of equipment furnace refractories.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned deficiency of the prior art, and a kind of method with manufacturing black microcrystalline glass plates from molybdenum tailings is provided, and this method has reduced production cost and temperature of fusion is low.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of method with manufacturing black microcrystalline glass plates from molybdenum tailings is characterized in that this method may further comprise the steps:
(1) preparation of glass batch: take by weighing by following weight part and to be mixed and made into glass batch behind each raw material: molybdenum mine tailing 50-70 part, quartz sand 15-25 part, Wingdale 25-35 part, soda ash 3-5 part, zinc oxide 2-4 part, barium carbonate 3-6 part, ferric oxide 3-6 part, Manganse Dioxide 0-1 part, nickel oxide 0-1 part, cobalt oxide 0-0.5 part;
(2) with cell furnace or cabinet-type electric furnace the described glass batch in the step (1) is fused into glass metal, glass metal is poured into becomes the glass particle material then in the water, and temperature of fusion is 1450~1480 ℃;
(3) the described glass particle material in the step (2) is tiled in the fireproof die, carry out crystallization and thermal treatment with tunnel furnace, shuttle kiln or cabinet-type electric furnace and become the black glass ceramic crude product, the black glass ceramic crude product is carried out becoming finished product after the grinding and cutting, and crystallization temperature is 1020~1080 ℃.
The composition of the raw material of glass batch described in the above-mentioned steps (1) is counted by weight: molybdenum mine tailing 50-70 part, quartz sand 15-25 part, Wingdale 25-35 part, soda ash 3-5 part, zinc oxide 2-4 part, barium carbonate 3-6 part, ferric oxide 3-6 part, Manganse Dioxide 0.5-1 part, nickel oxide 0.2-1 part, cobalt oxide 0.05-0.5 part.
The present invention compared with prior art has the following advantages:
1. the molybdenum mine tailing is a kind of mine waste, and it is occupied arable land, contaminate environment even might cause the disastrous accident of threat to life property safeties such as mine tailing storehouse dam break.It is used as a kind of composite industrial raw material can reduces its volume of cargo in storage, alleviate the harm of mine tailing ecotope.
2. because the molybdenum mine tailing is a kind of waste, so its other cost except trucking costs is zero substantially.Conventional raw materials such as it is used in the glass batch can instead of part quartz sand, aluminum oxide, magnesium oxide, soda ash, Wingdale can reduce the glass batch cost more than 20%.
3. after introducing the molybdenum mine tailing, need not add aluminum oxide again, reduced the consumption of industrial chemicals such as soda ash, Wingdale, and these raw materials all have very strong erosion action to refractory materials.Therefore under the constant condition of glass composition and temperature of fusion, can alleviate the erosion of glass metal to furnace refractories.
4. with behind the molybdenum mine tailing instead of part industrial chemicals, some has become compound in silicon-dioxide, these two kinds of infusibility components of aluminum oxide, therefore the temperature of fusion of glass can be reduced to 1480 ℃ from 1550 ℃.Also improve the speed of founding of glass simultaneously, thereby improved melting furnaces efficient, reduced energy consumption.
In a word, the benefit brought of the present invention is to reduce environmental pollution, reduce production costs.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.
