Through synthetic fluoromica prepared by this technique, limpid transparent, pliable and tough, the whiteness value of crystal wafer coarse breaking can reach 88 more than %; Crystal is greatly unilateral, and the synthetic fluoromica sheet ratio being greater than 4 order ranks can more than 75%; Synthetic fluoromica whitewash degree through grinding classification can reach 90-94%, and by the inspection of pearly-lustre parcel, its effect can reach the requirement of high-quality pearly pigment.
The present invention compared with prior art, has following beneficial effect:
(1) the furnace wall plate mainly formed with steel plate is adopted to build body of heater by laying bricks or stones, substitute traditional refractory brick, mechanical dismounting can be adopted on the one hand, significantly reduce the labour intensity of workman, the use saving refractory brick on the other hand (produces 8-11 ton product by original every stove, every stove loss hundreds of to thousand high alumina standard, wedge shape refractory brick), reduce production cost, again on the one hand, solve and use refractory brick building by laying bricks or stones, found, tearing open in the processes such as stove, the brick powder of generation, brick are broken, iron rust etc. is to the pollution of mixing raw material and product and etch.
(2) decrease the usage quantity of electrode: conventional synthesis stove uses the Graphite Electrodes of 150kg only can produce 8-11 ton product, and the present invention uses the Graphite Electrodes of 120kg can continuous seepage up to a hundred tons of products, greatly reduces production cost.
(3) cross-sectional area of the body of heater of synthetic furnace of the present invention is less, and liquation is only located in-between the electrodes and surrounding them substantially, and mixing raw material melts completely, glass melting temperature gradient is little, melting viscosity is even, and the formation of the wafer that is highly advantageous to, forms gem-quality crystal after cooling crystallization.
(4) can continuous seepage, save electric energy: conventional synthesis stove synthesizes every kilogram of fluorophlogopite product needs 1.29-1.32 degree electricity, and the present invention synthesizes every kilogram of fluorophlogopite product and only needs 0.86-1.07 degree electricity.
(5) for synthetic fluoromica, its recrystallization temperature is at 1375-1405 DEG C, and recrystallization temperature is extremely narrow, if speed of cooling is too fast, then the wafer generated is too little, all unfavorable to Yield and quality.Existing intermittent type circular furnace body, because namely blowing out stops energising, fast in the speed of cooling of this section of temperature, particularly small-sized body of heater, almost just exceeded this recrystallization temperature interval, so the growth of wafer is subject to great restriction at 2-3 hour, crystallization is incomplete, and wafer is hard, crisp, little.Synthetic furnace of the present invention is in normal melting process, not blowing out does not have a power failure, along with the slow propelling of electrode car, new mixing raw material melts, simultaneously, in crystallization district, crystal and saturated solution coexist, still small area analysis is had to pass through, liquation still has heat to send, thus delay speed of cooling, extend the time (synthetic furnace of the present invention can keep 7-12 hour in above-mentioned recrystallization temperature interval) of crystallization, be conducive to growth and the arrangement of chip architecture Atom of crystal, reduce the formation of defect in wafer, the wafer of synthesis is soft.Tough and size is large.
In brief, Opacity in lens stove of the present invention can effectively improve the quality of products, and artificial-synthetic crystal's materials such as synthetic fluoromica are produced under stable condition, improves the productive rate of high-quality artificial-synthetic crystal material, energy consumption greatly reduces simultaneously, and resource utilization is high.
In addition, synthetic furnace wide adaptability of the present invention, singly not can be applicable to the synthesis of artificial mica synthesis, can also be applied to the synthesis of artificial-synthetic crystal's materials such as Decorative Building Stone.
