Description
Technical field
The present invention relates to a kind of material and manufacture method of composite industrial product boccaro goods, belong to silicate and boccaro goods manufacturing technology field.
Background technology
Boccaro is a kind of of complex class silicate minerals, and purple clay is divided into to comprising three kinds in purple mud, green mud and red soil, and the general designation purple clay for opaque rock mud, is an aleuropelitic texture, and iron-holder is higher, and the main place of production is Yixing, Chinese Jiangsu.
The used main raw material of zisha earthenware is purple mud, and the expert describes that purple mud is that " bone " arranged in the mud.This " bone " is exactly the quartz particles in the purple mud, just " sand " in the purple clay.It and clay, mica, rhombohedral iron ore symbiosis one.
Purple mud is an interlayer of first mud ore bed, and ore body is lamelliform, lensing, and seam thickness is generally about tens centimeters to one meter, poor stability, the raw material appearance color is purple, red-purple, and has the light green spot, burns the back appearance color and then is purple, purple brown, atropurpureus.Purple mud major ingredient is a hydromica, and contains kaolin, quartz, scrap mica and the irony etc. of inequality.Analysis-by-synthesis, purple clay belong to grain soil-quartzy mica, and the quite characteristics of class porcelain making raw material, so single raw material of planting promptly have ideal plasticity-, moulded pottery not yet put in a kiln to bake intensity height, and drying shrinkage is little, for multiple moulding provides good processing condition.
Can be observed between the boccaro granule at microscopically, single mineral such as quartz, clay and granule between linear porosity, an and inner fine pores.And boccaro is different from the single crystal structure of conventional ceramic, and boccaro is dual air hole structure.The dual air hole structure that boccaro had, the boccaro goods that are have high stomatal frequency and certain void content.
Present boccaro Tao Xuan mud, the preparation of mud, existing technology such as burn till, has certain mechanical strength though make boccaro make pottery, but the iron oxide content in the purple clay is quite high, according to silicon-dioxide, aluminium sesquioxide, ferric oxide, ferric oxide ternary phase theory, burn till in oxidizing atmosphere as fruit product, then thing is not producing liquid phase figure below 1350 ℃, do not form eutectic mixture, owing in the purple clay chromic oxide is arranged still, magnesium oxide, potassium oxide, compositions such as sodium oxide, and the firing temperature that actual boccaro is made pottery mostly is 1100～1180 ℃ greatly, under this temperature, the velocity of diffusion of each mineral facies is little in the pug, rhombohedral iron ore does not exist mutually as a kind of, whole blank glassy phase is lower, make the cooling shrinking percentage of goods be about 15%, and the product bending strength is lower, precise measure influence to product is bigger, can't use as the accurate spare and accessory parts of industry.As burning till with reducing atmosphere, then only should be undertaken by silicon-dioxide, aluminium sesquioxide, iron oxide phasor, about 1100 ℃, form the eutectic eutectic and produce liquid phase.The a large amount of reducing iron oxides look of ferric oxide mud is black by purplish red purpling, and product surface shifts to an earlier date in the sintering and reducing process sedimentary charcoal gas plain and that decompose can't overflow and bubbling, carbon deposit take place, and causes waste product.
Can under lower Applicable temperature, fire a kind of composite industrial product boccaro goods, should satisfy the original service requirements of boccaro goods, can satisfy low-shrinkage, high-flexural strength and stomatal frequency and void content requirement again is technical problem to be solved by this invention.
Summary of the invention
Purpose of the present invention just provides a kind of composite industrial boccaro product material and manufacture method.
Purpose of the present invention can realize by following technical scheme.

3Powder 500 orders 1000 orders, synthetic bone meal 400 orders-500 order, the mean particle size of organic-inorganic softening agent and composite fluxing agent and mineral is smaller or equal to 10 μ m.
Mix pulping: with ground raw material blend pulping, adopt 1.8 to 2.5 ten thousand gaussian intensities to carry out deironing, press filt, the thick white silk, old, water treatment after filtration, moulding seasoning.
First sintering briquette: will dry material base and in kiln, fire through 1100 ℃ 1250 ℃, constant temperature 9 to 11 hours, back naturally cooling, to pulverize through the blank of first sintering briquette is 50 to 1000 order particles again, and this particle is carried out kneading by vacuum pugmill become ripe pug, add metal die at last again and become required machining shape, with the blank seasoning after the moulding.
Sintering briquette for the second time: with the blank after the seasoning, put into kiln, 4 to 5 hours firing times, adopt oxidizing atmosphere through 1380 ° to 1450 °.Be fired into the glassy phase order and produce the little pore of sealing uniformly, and the lightweight class boccaro ceramic products of tight burning.Naturally cooling is come out of the stove, the demoulding.
The present invention has the following advantages and effect:
(1) because the clay-quartz-mica that adopts high siliceous and high magnesia clay to change the rich iron in original purple clay is tied to form part, the less characteristics of contained glassy phase in the mineral make traditional red stoneware product possess the material character of class porcelain.
(2) adopt unique secondary high-temperature firing method, sintering briquette for the second time particularly, temperature is above 1350 °, broken through boccaro tradition firing temperature, the also firing temperature limit of pottery is just being fired aspect the condition, possessed the character that generates the class porcelain products, blank can tight burning.
(3) owing to adopted the organic-inorganic softening agent, improved the plasticity of mixing pug, further promoted original purple clay plasticity-, make better moulding of blank, be convenient to accurately process required different shape exemplar.
(4) owing to added composite fluxing agent and mineralizer, realized base substrate minimum temperature moulding in baking temperature range, under the situation that becomes the class porcelain, temperature is only at 1380 ° to 1450 °.
(5) owing to added α-AL
