1,4 cutting---polishing---check---finished product packing
Multi color pattern glaze blanket work in-process are cut to specified dimension, form bright or dull surface through being polished to the surface, and again through check, packing obtains the fiber porcelain plate with vitrification glaze finished product.
This routine fiber ceramic board is the multi-layer compound structure of vitreous colorant patterned layer---glazed layer---aggregate stratum basale, checks congruent melting mutually between the section visible layer, oozes and connect the compound one that is; Be of a size of length * wide * thick=3500mm * 2000mm * 3mm;
Appearance surfaces is bright or dull surface, and glaze densification, exquisiteness, exquisiteness do not have macroscopic pore, and overall leveling is bright and clean, does not have depression, protrudingly sticks up distortion or be full of cracks, has elasticity as the timber, section is fibrous crystalline state;
The physical and chemical parameter value is not fired; Water-intake rate 2.03%; Folding strength, laterally 38N/cm
2, vertical 43N/cm
2Sinuousness 27mm; Thermal expansivity 68 * 10
-7/ ℃; Freeze-thaw test (+20～-35 ℃) is excellent; Thermal shock resistance (180 ℃) is excellent.
Raw material of the present invention is formed rationally, and the flux raw material is arranged in the prescription, the feldspar of fluxing as low temperature, the wollastonite that high temperature is fluxed, is easy to low sintering clay, low temperature porcelain stone etc.; The prescription and the stratum basale of glaze layer adapt, and comprise maturing range, and the adaptation between the coefficient of expansion; Wollastonite has two effects, and the one, use its crystalline different orientation, form the compound interlacing whippy thin stock of inorganic fibre layer by layer, strengthened the toughness and the elasticity of product; The 2nd, except introducing sial, introduced the component of calcium, having constituted silicon-aluminium-calcium is the eutectic system of main component, the thing that generates mainly is lime feldspar mutually, realize that this reaction only need get final product under the condition of lesser temps, because wollastonite itself does not contain organism, crystal water and absorption water; From differential thermal curve, wollastonite did not significantly absorb heat before 1200 ℃, exothermic effect, and rapid phase transitionization does not take place;
The wollastonite prescription more is applicable to rapid drying, fast dewatering, and the easier quartzy crystal formation transformation point that passes through 673 ℃ meets the condition of burning till fast at pre-heating stage.
Because " neutral " after aggregate stratum basale first sintering is discharged crystal water, phase clinkering crystal structure is tentatively finalized the design, this moment, the crystal plane of coarse crystal plane of aggregate stratum basale and cover coat (---cover coat---printing glaze layer via Jie's cover coat) connected airtight, again the second time after glazing 1100～1200 ℃ of congruent melting sintering, the mutual congruent melting of interlayer, ooze connect compound for one, can really reach densification, lower the water-intake rate of finished product greatly, and effectively prevent the generation of " cold cracking " defective.
Quality index obviously is better than prior art, has reached the goal of the invention of expection.

Take by weighing each feed composition of stratum basale according to dosage, except that wollastonite, all the other major ingredients and additive add wollastonite after being crushed to granularity≤200 orders again; The abundant mixing of raw material adds water, the pug of mixing one-tenth water content 15～20%; Pug is the output of successive blank through the shaper extruding; Through multistage roll extrusion, cut the green compact body that becomes length * wide * thick=2050～3550mm * 1050～2080mm * 3～6mm; The green compact body is at 100～300 ℃, dry 0.5～3h; Dried green compact body is at 800～1000 ℃, and 0.5～3h is sintered into aggregate stratum basale work in-process---skeleton blanket;
(3) glazing---congruent melting sintering, preparation glaze blanket
Take by weighing each feed composition according to dosage at every turn, press the ceramic industry routine, mixing grinds, and sieves the preparation glaze slip;
Press the conventional enameling method of ceramic tile, Jie's cover coat, cover coat and printing glaze layer divide three layers of glazing successively, glaze slip imposed on aggregate stratum basale work in-process---skeleton is used the blanket surface, after the first layer glazed layer is done, execute down one deck again,---cover coat---Jie's cover coat---aggregate stratum basale, oozes and connects at the mutual congruent melting of interlayer at last again through 1000～1250 ℃ of congruent melting sintering, to form the printing glaze layer
Multi color pattern glaze blanket work in-process;
(4) cutting---polishing---check---finished product packing
Multi color pattern glaze blanket work in-process are cut to specified dimension, form bright, dull surface through being polished to the surface, and again through check, packing obtains the fiber porcelain plate with vitrification glaze finished product.
3. according to the preparation method in industrial scale of the described fiber porcelain plate with vitrification glaze of claim 2, the long-width ratio that it is characterized in that described wollastonite fibre is long: wide=1 :≤20.
4. according to the described fiber porcelain plate with vitrification glaze of claim 1, it is characterized in that described vitreous printing glaze layer end face, also be provided with patterned layer.
5. according to the preparation method in industrial scale of the described fiber porcelain plate with vitrification glaze of claim 2, it is characterized in that described vitreous printing glaze layer end face, can also repeatedly draw or the printing pattern layer, again through 800～1000 ℃ of sintering.
