Technical background
Microcrystalline glass decorative plate has been popularized about ten years history, and has set up industry standard (architectural decoration devitrified glass JC/T872-2000).In recent years, develop on this basis again and a kind of devitrified glass ceramics composite brick: the devitrified glass surface layer of sintering one number of plies mm thick on the vitreous ceramic tiles ground.Traditionally, generally " " crystallizing glass sheet material that is limited is referred to as the whole-body crystallized glass plate to industry standard JC/T872-2000; And the devitrified glass ceramics composite brick is referred to as crystallite glass composite plate.
The diversified demand of assortment is the eternal theme of finishing material all the time.The current already glaze method surface colour art of ceramic industry.In fact, this painted principle also has been applied to the production practice of whole-body crystallized glass plate (being called for short the entire body plate) and crystallite glass composite plate (abbreviation composition board).Aspect the basic link of Production Flow Chart; no matter entire body plate or composition board; all be at first other glass ceramics frit particle of millimeter level to be tiled in the refractory-material dies that internal surface scribbles releasing agent on (for the entire body plate) or the vitreous ceramic tiles face as ground (usually composition board also being needed the spraying and adhesive bonding agent in addition) by certain thickness; then the microcrystalline technology that passes through high temperature sintering and carry out is simultaneously made whole bulk sheet material.On the glazed surface of the sheet material that obtains like this, an original glass ceramics frit particle is promptly corresponding to an emulsifying granule shape colony on the plate face (i.e. a shape druse), and vice versa; And the borderline region between the original glass ceramics frit particle just forms the reticulate pattern of a lower slightly relatively one point union of opacity through whole surface.
Above-mentioned a kind of like this texture, the while also just provides the painted approach of a kind of special being referred to as " colored glaze powder entrapping method " for the mother glass particle surface layer of entire body plate and composition board, following two schemes are arranged in the middle of the enforcement.The first string is " sticking glaze slurries hybrid packet is buried method ": will be mixed with the suitable color glaze slurry of binding agent and viscosity and mix oven dry again with the glass ceramics frit particle by suitable proportion, just can in fact make skim colored glaze powder film in all enough all even embedding securely of all glass ceramics frit particles, through the dress mould, burn till, on the microcrystal glass plate face after the grinding and polishing, whole reticulate pattern background just manifests the color that is interacted and formed by glaze colours and glass ceramics frit color, and when glass ceramics frit very slight color or white, whole reticulate pattern background just manifests the basic color corresponding with described color glaze, the then still basic inherent colour that keeps described glass ceramics frit of the colony corresponding with described primary particle, colourless glass ceramics frit is just obtained oyster white, then can still the dyeing film of upper strata, top primary particle upper face can not be ground off fully when stock removal is very little, corresponding with described primary particle in this case colony will manifest the intermediate color between light glaze colours or glaze colours and the glass ceramics frit color.In some specific occasion; especially in the Production Flow Chart of entire body plate; even second scheme that is " dry color powdered frit wet glass particle mixes pack " that can use simplification: the glass ceramics frit particle of the water ratio that will suit directly mixes the purpose that the realization colored glaze powder is wrapped up glass particle with the colored glaze powder of suitable proportion; as long as take advantage of the wet glass ceramics frit particle and the fashionable dress mould that will wrap up like this, advance klining, just can satisfy the painted technology purpose of reticulate pattern.This painted flow process, need extra operation place and equipment for the first string, second scheme then firmness of integument is very low, if will will cause painted irregular even serious uneven consequence through the process procedure that may cause the colored glaze powder rete to come off behind the parcel.
Summary of the invention
In the middle of the content and after this down statement of this paper before this, different occasions are used term " mother glass particle " and term " glass ceramics frit particle " respectively, these two terms are equal to herein, just claim " devitrified glass mother glass " and claim " glass ceramics frit " in composition board field habit in entire body plate field habit.
The present invention is directed to above-mentioned shortcoming make improve as follows: do not increase extra drying plant, be right after after the stone line, 1. aim at completed the glass ceramics frit granular layer wait to burn till composition board upper surface (then is to aim at the mother glass granular layer upper surface of having completed on the refractory-material dies plate to the entire body plate), color glaze slip with the prior good fluidity of having prepared, through suitable technology, such as spraying, showering, or get rid of mode such as spill, execute skim color glair, 2. replenish an amount of water with the same manner in above-mentioned scope again and promote described glaze slip toward the depth of penetration of this glass ceramics frit granular layer or not through this moisturizing operation, 3. then with ready like this composition board base substrate (then is together with the mother glass particle after the described glaze slip osmotic treated of the process of institute's splendid attire with refractory-material dies to the entire body plate), experience is dry or moist, 4. then burn till again, grinding and polishing processing, 5. promptly on the devitrified glass surface of made sheet material, produce matrix color and reticulate pattern color decorative effect differing from each other that dispersion colony as described above is formed.
The present invention does not have special requirement to various device involved in the above-mentioned introduction, that is the present invention is applicable to existing relevant universal industrial equipment.Equally, will make suitable explanation to various related process flow process materials involved in the above-mentioned introduction herein: no matter particle sintering process technology is belonged to that a kind of glass chemistry compositional system with the mother glass particle of devitrified glass, the present invention is not particularly limited condition but obviously completely is suitable for; For described color glaze slip, the present invention is not particularly limited condition, that is existing ceramic industry colored glaze powder, glaze slip obviously are suitable in principle without exception, colored glaze powder just can influence the strong and weak and quality height of effect of finished pigmented in the variety variations aspect color and the chemical ingredients, and does not have problem basic and that the present invention conflicts; The painted viscosity with the color glaze slip of described infiltration changes, equally also just can influence the strong and weak and quality height of effect of finished pigmented, because as long as a kind of glaze slip is can mobile, this glaze slip just must have certain osmosis with the mother glass granulation mass lamination of devitrified glass for the particle sintering process technology of conventional condition of surface (not handled by surperficial water-repellent agent), thereby also just obviously is applicable to the present invention.
In order to control the quantity of the good fluidity color glaze slip that applied and distributing homogeneity thereby enough depth of penetration uniformly just well, only the control such measure of coating quantity that applies described color glaze slip does not often reach desired promising result.Can consider, only be that this factor of fluctuating of glass ceramics frit tap density will often make that the infiltration thickness low LCL is even; At this difficulty, the present invention developed foregoing invention the in introducing 2. step (moisturizing) promote depth of penetration: after being right after on the glass ceramics frit accumulation body surface of the color glaze slip of good fluidity having been adorned mould (that is long-pending good) through suitable technology paint by the definite shape shop, replenish with same procedure more immediately and apply an amount of water, under the dual function of the extruding of the gravity of institute's moisturizing layer and appropriate " drip washing and dilution ", thereby the coloured glaze slurries that last procedure applied not only can the infiltration of further past more position, deep increase effective depth of penetration, and the original depth of penetration non-uniform phenomenon that often occurs also is improved.Test shows, regulate concentration, flowing property, the unit surface applied amounts of described color glaze slip, and the unit surface applied amounts of described moisturizing operation, just in fact can make the depth of penetration of described color glaze slip and homogeneity all reach and meet the requirements, on the devitrified glass surface of the finished product, obtain satisfied coloring effect.
The palpus explanation, core part of the present invention is " suitable mobile suspension liquid color glaze slip is painted to the infiltration of mother glass granulation mass lamination ", in concrete application practice, only adopt existing industrial application technology, just can make much about modified version of the present invention fully.For example, only above-mentioned steps 1. (glazing slurry) and step 2. (short infiltration) make a little little changes, just be enough to produce the different decorative pattern of feature: analogy, 2. (promoting infiltration) when step is to see through certain mask, it for example is the A word of hollow out, when carrying out the moisturizing operation, just can aspect the color glaze depth of penetration, produce the three-dimensional difference of height, when being roughly parallel to after the surface carries out grinding and polishing processing, the color pattern of glazed surface will be deferred to the 2. rule of (promote infiltration) used mask decision of step, that is displays one and obviously increase the corresponding color pattern in zone (promptly aforementioned " the A word of hollow out ") with the bleeding degree of depth.Continue to say, the cage plate pattern paint-on technique that development is come out in the existing ceramic colour glaze application technique, that is a plurality of masterplates coordinate to apply the technology of a pattern (no matter shelter or superpose or the two combination) step by step, can both play a role in field involved in the present invention; In addition, in 5 job steps of being divided in the invention description of the preceding paragraph, the order of preceding 3 steps or aspects such as merging, combination can be made many kinds and change; And above-mentioned all these classes are changed, no matter be that the cage plate pattern applies or the adjustment of process changes, all do not exceed core frame of the present invention without exception, that is suitable mobile suspension liquid glaze slip is painted to the infiltration of mother glass granulation mass lamination, and therefore described this or that change all belongs to useful range of the present invention without exception.
The present invention can be summarized as on the basis of the above:
A kind of color glaze slip permeating coloring process of devitrified glass is characterized in that may further comprise the steps:
A) color glaze slip paint having been adorned mould or shop amasss on the glass ceramics frit particle packing surface on the porcelain brick ground;
B) make and to be starched painted glass ceramics frit particle stack experience by described coloured glaze and burn till and grinding and polishing processing, on described devitrified glass surface, obtain the color corresponding with the color glaze slip.
Randomly, can before or after step a), also comprise step a '): replenished the aqueous solution that applies water or be mixed with tensio-active agent by the painted glass ceramics frit accumulation body of glaze slip to described at suitable depth range, with the depth of penetration that increases and regulate described glaze slip, and improve the uneven phenomenon of depth of penetration, thereby reach better painted artistic effect.
In step a), be used for carrying out the painted good fluidity color glaze slip of described glaze slip infiltration, it prepares component proportions, proportion, viscosity Engler, parameters such as unit surface applied amounts are respectively: the preparation component proportions of glaze slip is 100 weight quota with (colored glaze powder+water), the weight quota of suspension agent (colored glaze powder+water) 100 outside add separately, weight quota optimum range separately is respectively a colored glaze powder 0.05~60, water 40~100, current race in the ceramic glaze field no chamotte glaze suspension agent---for example Xylo-Mucine 0.01~1.0, can suitably adjust when its adding proportion needs when adopting other existing glaze suspension agent, optimum range is a colored glaze powder 20~50, water 50~80, current race in the ceramic glaze field no chamotte glaze suspension agent---for example Xylo-Mucine 0.2~0.4, can suitably adjust when its adding proportion needs when adopting other existing glaze suspension agent; Also can add when needing in addition and mix the existing defoamer in ceramic glaze field, the weight quota of described defoamer (colored glaze powder+water) 100 outside add separately, as add 0.01~0.1 modified dimethyl polysiloxane as defoamer; The optimum range of viscosity Engler is 12~40 seconds, and optimum range is 15~20 seconds.
According to the present invention,, can obtain different decorative artistic effects by the described sequence of events of appropriate change or suitably adopting the existing pattern application technique in ceramic colour glaze field in the cargo handling operation.It can be flexile that described sequence of events changes, for example described glaze slip is applied operation and make up operation unit as one with described moisturizing operation subsequently, sequencing in this combination operation unit is put upside down, that is the aqueous solution that applies suitable quantity of water earlier or be mixed with tensio-active agent is improved described glass ceramics frit particulate wetting property, perviousness then applies described glaze slip again, can change the effective concentration of glaze slip on the depth of penetration of glaze slip and even the different depths level, the finished product surface of result after grinding and polishing obtains abundanter color, color range effect; And when a plurality of described combination operation units of plan employing, can execute water after the first glazing within each unit, also can execute glazing behind the water earlier, the different combination operation unit of these inside processing orders is carried out according to the order that designs, can obtain finer color, color range effect in the finished product surface after grinding and polishing.The pattern application technique that described ceramic colour glaze field is existing promptly is the cage plate pattern paint-on technique that development is come out in the ceramic glazing art, that is a plurality of masterplate coordinates to apply the technology of a pattern (no matter shelter or superpose or the two makes up) step by step.
Main 4 points that show of advantage of the present invention.The firstth, the colored glaze powder saving: in fact like this degree of depth of bleeding can be grasped just rightly, and only the down painted skim of slave plate face top surface satisfies the decoration needs, more the position, deep all do not have painted, thereby save the colored glaze powder consumption significantly.The secondth, workload is saved: especially show the most obviously when with above-mentioned the first string comparison.The 3rd is that operation is easy to control: for permeating the technology actual needs that operation is carried out fast; the used glaze slurry viscosity of the present invention should be starkly lower than common ceramic glaze slip; so mobile grow; just make that to apply homogeneity control easier, particularly mix pack and compare this just decided advantage especially with aforesaid dry color powdered frit wet glass particle.The 4th is that firm coloration is will never fade: this is directly to have inherited the painted Inherent advantage of ceramic glaze method high temperature sintering.
