Abstract
The present invention is nanometer film plating process and machine for glazed ceramic tile, and belongs to the field of glazed ceramic tile technology. The process of forming nanometer film onto the surface of glazed ceramic tile includes the steps of: fixing glazed ceramic tile onto one sol pond, filling the pond with sol and exhausting sol from the pond to attach one layer of sol film onto the surface of glazed ceramic tile, and post drying the glazed ceramic tile to form the nanometer film. The nanometer film plating machine is one sealed sol pond with sol inlet, sol outlet and glazed ceramic tile fixture. The present invention is scientific, simple and practical and can obtain high quality homogeneous film. The present invention is also suitable for single-sided coating of plate glass.
Description
Technical field
The present invention relates to a kind of method and nano thin-film coating machine that on glaze for glazed tile, prepares nano thin-film, belong to the glaze for glazed tile technical field.
Background technology
Glaze for glazed tile comprises ceramic inner wall brick, exterior wall tile and floor tile etc., is architectural traditional decoration finishing material commonly used, and for example ceramic inner wall brick is mainly used in the metope of kitchen and toilet, and is attractive in appearance and clean and tidy in the energy holding chamber, cleans easily.If plating one deck nano thin-film gives traditional ceramics new function on ceramic surface, then can increase its use value greatly, as carry out TiO
2Plated film can play effect antibiotic, self-cleaning, that purify the air of a room.At present, plating TiO on other base material matrix
2What nano thin-film adopted is sol-gal process, use dipping to lift technology, be that clean base plate is immersed in the colloidal sol, with certain speed substrate is vertically mentioned to breaking away from liquid level then, colloidal sol forms gel film at substrate surface, obtain the function corresponding film through super-dry and heat treatment, suitable double-sided coating.But find that in application in practice there are the following problems at the ceramic brick surface plated film: (1) can not contact with colloidal sol because the ceramic side and the back side have certain water absorption rate, therefore can't adopt common dipping to lift sol-gal process and carry out large-area coating film; When (2) colloidal sol being adopted film plating process such as brushing, spraying, roller coating, blade coating, printing, the bad grasp of the uniformity of coating film thickness is because TiO
2Refractive index very high, the minor variations of thickness also abnormal interference colors can occur, causes coating quality be difficult for to guarantee.
Summary of the invention
The object of the present invention is to provide a kind of method that on glaze for glazed tile, prepares nano thin-film, scientific and reasonable, simple; The nano thin-film coating machine of adapted is provided simultaneously, simple in structure, easy to use, processing ease.
The method that on glaze for glazed tile, prepares nano thin-film of the present invention, be that glaze for glazed tile is attached on the colloidal sol soaking pit wall, in the colloidal sol soaking pit, charge into colloidal sol, and then bottom the colloidal sol soaking pit, colloidal sol is emitted, one deck dissolved glue film is promptly enclosed on the glaze for glazed tile surface, to carry out post processings such as drying, heat treatment with the glaze for glazed tile of dissolved glue film, and can make and enclose one deck nano thin-film on the glaze for glazed tile.
Glaze for glazed tile can be attached to the hermatic door inboard of colloidal sol soaking pit, simple.
The dipping process of lifting of sol-gal process is that liquid is static, substrate moves upward, form double-sided coating, compare with the dip-coating method of sol-gal process, the inventive method has adopted the mode of reverse thinking, fixedly glaze for glazed tile is motionless, the sol liquid liquid level is flowed downward reposefully, form plated film.By the concentration of control colloidal sol or the flowing velocity of viscosity and liquid, can obtain the homogeneous film of different thickness, also can pass through repeatedly plated film and obtain thicker film, solved the problem of glaze for glazed tile large-area coating film.
Cooperate said method, used nano thin-film coating machine, the colloidal sol soaking pit that has a usefulness frame and hermatic door to constitute, the hermatic door medial surface is provided with the glaze for glazed tile fixture, so that glaze for glazed tile is fixed in the above,, on the lower frame of frame, establishes colloidal sol and import and export as slot, supporting plate and other hook etc.It also can be to be provided with respectively that colloidal sol is imported and exported, and the colloidal sol import can be located at top or top.
Hermatic door wherein can be the door that dissociates, and also can be the switch door that is fixed on the frame, by hinge pin connection etc.
Glazed tile is fixed on the hermatic door medial surface, close to the doorstep, glazed tile has constituted a part of colloidal sol soaking pit wall, at this moment, adds colloidal sol from the colloidal sol import and export in the colloidal sol soaking pit, flush with the top edge of glazed tile to liquid level, behind liquid level stabilizing, to import and export from colloidal sol again and bleed off colloidal sol, the liquid level stabilizing in the colloidal sol soaking pit steadily descends, on glazed tile, enclose the layer of even dissolved glue film, can make through post processings such as oven dry and enclose one deck nano thin-film on the glaze for glazed tile.Simple in structure, easy to use, processing ease.
Establish blow vent on the upper side frame of frame, adding, the discharge of assurance colloidal sol are unimpeded, prevent to produce bubble, promote even plated film.Also can not establish upper side frame, open topped gets final product.
Add sealing ring between colloidal sol soaking pit frame and hermatic door inboard, strengthen sealing property, sealing ring can be located on the frame, also can be located at the hermatic door inboard, guarantees that the excellent sealing between frame and hermatic door gets final product.The rubber of sealing ring available silicon rubber or acid-resistant and heat-resistant is made,
The hermatic door design there are relative two, even can be designed as relative two couple, improve plated film efficient.
Bottom at the colloidal sol soaking pit connects liquid level gauge, is convenient to the colloidal sol liquid level and observes, convenient accurately operation.
Among the present invention, colloidal sol can be the general plated film colloidal sol of industry, also can be the plated film colloidal sol of newly developing.Add the colloidal sol operation and can set up fluid reservoir, take the pressure method for implanting.The caliber size control of speed when colloidal sol flows out by importing and exporting.Subsequent treatment such as the drying behind the plated film, heat treatment are the same with other film plating process.Technology contents same as the prior art repeats no more.
With the super flat glaze for glazed tile of 300 * 450mm is the example test, has successfully plated out the nano-TiO of surface-brightening, no interference colours on the glaze for glazed tile surface
2Antibacterial film.
The present invention prepares the method for nano thin-film on glaze for glazed tile, scientific and reasonable, and is simple; The nano thin-film coating machine of adapted is simple in structure, easy to use, and processing ease is beneficial to and obtains high-quality even plated film.The inventive method also can be carried out coating single side on plate glass.
