In order to avoid the fluorine-containing waste liquid that produces production process and waste water are to environment, therefore, need through purifying treatment, the method that the technical program adopts has two kinds:
Method one: limestone vegetation method; The pH value of the waste water of discharge is kept to reach 8.5.
Method two: the precipitator method in limestone vegetation+Tai-Ace S 150.
Below the equipment corresponding with the preparation method of described dumb light brick, it comprises the reaction tank 1 that the acidic solution containing fluorochemical is housed, the washing pool 2 that set gradually, the top of washing pool 2 is provided with water washing spray head 7, reaction tank arranges the container 3 that promotor is housed outward, and the discharge port of container guides reaction tank 1 into.The discharge port of container arranges the valve 4 being connected with Controlling System, PH meter 5 is provided with in reaction tank 1, the signal output part of PH meter is connected with PLC control system 6, by the opening and closing degree of PLC control system by-pass valve control 4, makes the addition of promotor and blanking velocity all controlled.
It should be noted that, in order to avoid to environment, the sour water formed in brick body process after washing pool cleaning acid etching also needs to carry out environmental protection treatment before outwardly discharging, as the sewage draining exit at washing pool connects the treating pond 9 that liming or other basic solution are housed.
In order to increase work efficiency, at the input and output side of reaction tank, washing pool, can also ceramic tile e Foerderanlage be set respectively, ceramic tile is sent in reaction tank automatically, sending in washing pool again after corrosion reaction and wash.Arrange air-dry apparatus 8 at the output terminal of washing pool, this air-dry apparatus comprises air-dry platform and is arranged on the outer and blower fan of blowing towards air-dry platform of air-dry platform, accelerates the rate of drying of ceramic tile.The output terminal of air-dry apparatus is provided with chemical rightenning station, can form good clean bright anti-fouling effect through the brick surface of chemical rightenning.
The technical program adopts the method for chemical corrosion to make ceramic brick surface generate matte surface, and by adding promotor in corrosion reaction process, it can be made to form the effect of non-uniform corrosion, obtain through a large amount of test, the glossiness of the matte surface of the ceramic product adopting the technical program to process can within the scope of 0-25 degree, M ± 2 ° can be controlled in, and the matte surface that traditional mechanical mill mode processes has polishing scratch mark, anti-fouling effect is bad, not can be used as floor tile practicality, and glossiness is 9-30 degree, by contrast, the matte surface of the ceramic product of the present invention's processing is without polishing scratch, without wave, relative smooth, bottom pattern can clearly show, softer, nature.
The chemical dumb light that the present invention adopts is compared with existing mechanical dumb light mode, although be all form rough hair side on the surface of brick, but both are distinguishing, machinery dumb light (grinding and polishing process) forms the process of hair side, belong to the mechanical workout on surface, and chemical dumb light is the reactant that process of chemical attack generates indissoluble, becoming small-particle crystal is attached on the surface of brick, different with acid solution exposure level from the surface of particulate interspaces under particle, erosion degree is different, thus make surface irregularity, belong to chemical treatment; Some surface chemical composition throwing glazed brick are different, except above-mentioned effect, also there will be erosion degree difference, thus Aided Generation hair side, form dumb light brick.Acid etching surface is fine and smooth, can be antifouling after being for further processing, and can be used as floor tile and uses; And the brick surfaceness of machinery mill is large, having done further process can not be effectively antifouling, namely can filler particles shape material, therefore can not use as floor tile.
It should be noted that, the present invention is different from existing mechanical dumb light mode, open brand-new approach-chemically production dumb light brick in addition, not only production technique is simple, improve the efficiency of production greatly and reduce production cost, and the product performance of producing are more superior, create unexpected technique effect.
Above-described is only the preferred embodiment of the present invention; should be understood that; the present invention not only may be used for general ceramic polished brick processing; can also for the ceramic tile having enamel surfaces; or devitrified glass brick etc., for the person of ordinary skill of the art, without departing from the concept of the premise of the invention; can also make some distortion and improvement, these all belong to protection scope of the present invention.
