Description
Technical field
The invention belongs to the ceramic category, particularly a kind of wholly vitrificated inorfil ceramic board and preparation method in industrial scale thereof.
Background technology
Large format ceramic plate of the prior art, though or glaze, its water-intake rate 〉=10% arranged; Though or water-intake rate≤3%, belong to the sintered plate of vegetarian noodles, porous surface, easily contaminated, cannot say for sure clean, easy cleaning not; Make large format ceramic plate product, in use the beautifying and decorating poor performance.
The applicant has done many improvement researchs to this; under the condition of repeatedly burning till, industrial-scale production goes out congruent melting, ooze the fiber porcelain plate with vitrification glaze that connects to one (vitreous printing glaze layer---cover coat---Jie's cover coat---multi-layer compound structure of aggregate stratum basale).The application continues to improve to it, enriches the three-dimensional level of fiber ceramic board, strengthens its beautifying and decorating performance.
Summary of the invention
Purpose of the present invention is to develop once-firing, low water absorption, a kind of wholly vitrificated inorfil ceramic board and preparation method in industrial scale thereof.
The objective of the invention is to implement by following technical solution:
Develop a kind of wholly vitrificated inorfil ceramic board, it is characterized in that:
By the compound of plasticity-ceramic raw material and colour glaze, and the inorganic fibre skeleton constitutes;
Skeleton is the interlacing layer by layer network structure of inorganic fibre, through oversintering and ceramic raw material and colour glaze congruent melting, ooze connect compound for one;
Its surface is bright fine and close or a dull surface, has plane or sculptured decorative pattern, patterning;
Do not fire; Water-intake rate≤2.5%; Folding strength, laterally 〉=37N/cm
2, vertically 〉=42N/cm
2Sinuousness 〉=20mm; Thermal expansivity≤75 * 10
-7/ ℃; + 20～-35 ℃ of freezing and thawing test are excellent; 180 ℃ of thermal shock resistances are excellent; Do not have macroscopic pore, integral body has elasticity as the timber, section is fibrous crystalline state;
Its whole specification is length * wide * thick=2000～3500mm * 1000～2000mm * 3～6mm.
The preparation method in industrial scale of above-mentioned wholly vitrificated inorfil ceramic board is characterized in that processing step is as follows,
(1) batching
The raw material weight component:

(2) pulverize, green compact are body formed, drying and work in-process sintering
Take by weighing each feed composition according to dosage, except that the wollastonite fiber, the compound of plasticity-ceramic raw material and colour glaze adds wollastonite fibre after being crushed to granularity≤200 orders again, and fully mixing 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;
After dried green compact type is cut,, form congruent melting, ooze the colored blanket work in-process that connect at 1000～1250 ℃ of congruent melting sintering;
(3) cut---polishing---check-finished product packing
Colored 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 entire body vitreous plane fiber ceramic board finished product.
The another kind of preparation method in industrial scale of above-mentioned wholly vitrificated inorfil ceramic board, it is characterized in that described green compact body through embossed surface, cut after, at 100～300 ℃ of drying 0.5～3h,, form congruent melting, ooze the sculptured colored blanket work in-process that connect again at 1000～1250 ℃ of congruent melting sintering; Enter and cut---check---finished product packing again, obtain the sculptured fiber ceramic board finished product of entire body vitreous;
The preparation method in industrial scale of above-mentioned wholly vitrificated inorfil ceramic board, the long-width ratio that it is characterized in that described wollastonite fibre is long: wide=16.5～20: 1.
Advantage of the present invention is:
1. in batching, contain inorganic fibre wollastonite framework, interlacing layer by layer network structure, through the oversintering congruent melting, ooze connect compound for one; The whole congruent melting of its inorganic fibre skeleton---ceramic raw material---colour glaze, ooze and connect the compound one that is, strengthened the toughness and the elasticity of product; Form large format, ultra-thin, high-elastic, surface compact does not have pore, the glass face is bright and clean, and low water absorption is difficult for contaminatedly, easily keeps a public place clean, and easy cleaning has the novel characteristic fiber ceramic board of good workability.
2.---cover coat---Jie's cover coat---is compared by the fiber porcelain plate with vitrification glaze of the multi-layer compound structure of aggregate stratum basale for the present invention and vitreous printing glaze layer, also add the base inorganic color in the batching, can once-firing be entire body vitreous embossment fiber ceramic board finished product, or entire body vitreous plane fiber ceramic board finished product; Work simplification, energy-conservation, joint consumption reduces cost.
3. the surface can embossing, and the structure of imitation natural stone and texture form special cameo effect, have increased the large format fiber ceramic board new variety of another kind of form; Enrich the three-dimensional level of fiber ceramic board, strengthen its beautifying and decorating performance.
