Description
Technical field
The invention belongs to the manufacturing technology of ceramic image.
Background technology
Pottery image dish is that picture is transferred on the ceramic disk by the mode that heat shifts, the heat transfer technology of domestic and international existing baking ceramic image dish, be to shift ink with heat picture to be printed on the color spray paper, again the anti-ceramic disk surface of coating immersion coating that is attached to of the picture paper of being printed by printer.Be pressed onto ceramic card with a roasting head and be added to certain pressure picture paper and card are adjacent to, 180-210 ℃ of roasting head heating makes heat shift China ink and transfers to inside the coating on ceramic disk surface, so just carried out a ceramic image dish.What this technology adopted is the mode of utilizing roasting head direct heating picture and ceramic card, roasting head is to make with the iron plate and the silica gel plate on a plane, and folder is gone up heating wire and electroheat pair between the silica gel plate, and heating wire is used for heating, electroheat pair is used to measure temperature, and iron plate being used to exerts pressure.The highest short time bearing temperature of silica gel plate has only 250 ℃ and can not maintain on this temperature for a long time, and the best transition temperature of heat transfer China ink is 180-200 ℃, keep this temperature at roasting head and porcelain dish surface so, silica gel plate between heating wire and the porcelain dish can not be too thick, and the temperature on too thick porcelain dish surface does not reach 180-200 ℃.If 180-200 ℃ of temperature can be kept in the porcelain dish surface, surpassed the highest short time bearing temperature of silica gel plate, easily silica gel plate has been burnt.Therefore the silica gel plate between porcelain dish and the heating wire can only be used the thickness of 2-3 millimeter.Because used silica gel plate is thinner, ceramic disk has uneven just being difficult to that picture is compressed slightly, and the place that is adjacent to is just roasting has painted, and the place that does not compress is just roasting does not paint, and whole like this porcelain dish is just useless.The temperature of roasting face in front and plate edge is more or less the same when just having begun to bake 1-2 dish, and the porcelain dish of baking is also relatively good, and the time one is long, and the heat radiation in the place of roasting contact and the temperature difference of plate edge are just big, and the ceramic disk center is roasting has stuck with paste, on the picture of roasting head edge is also roasting.Therefore a roasting head can only be fit to baking and the roasting big picture of first sample, and can not work long hours, and roasting going up severally needs cooling a few minutes to use again.Because roasting head heating directly contacts with the ceramic disk part, ceramic disk can not thermally equivalent, is easy to burst.Therefore at present the domestic and international technology that adopts has limitation, and 1, roasting head can not work long hours; 2, roasting head burns out easily; 3, the ceramic disk flatness is required high, rough ceramic disk can not baking, and a plurality of sizes of baking must be equipped with corresponding a plurality of roasting heads; 4, ceramic disk that can only the baking specific dimensions, ceramic disk that can only the baking smallclothes.Because roasting head directly is pressed in roasting picture on the plane of ceramic disk, the size shape of ceramic disk is restricted, the planar dimension of trying to get to the heart of a matter with roasting area of bed is unmatched can not baking.At present only do 3 general sizes both at home and abroad, promptly the picture diameter is 85,125,150 millimeters a ceramic disk.5, heating is inhomogeneous; 6, the roasting easily porcelain dish that splits in the heating process.
Summary of the invention
It is unrestricted that technical problem to be solved by this invention provides a kind of ceramic disk shape and size, and homogeneous heating is not subjected to the ceramic image dish method for baking that limits heat time heating time.
Ceramic image dish method for baking of the present invention, it is characterized in that ceramic disk is placed on the metal wire side, scribble immersion coating on the pottery card, image frame paper is attached to coating surface, be pressed with the heatproof elastomeric material on the picture paper, be pressed with pressure plare above the elastomeric material again, thermal source is set in the bottom of ceramic disk, thermal source does not directly contact with the ceramic disk bottom, and thermal source heating ceramic dish makes the temperature on the ceramic disk card reach 180-200 ℃.
Technical characterstic that the present invention gives prominence to be changed the roasting head of prior art directly the heating porcelain dish mode and adopted the mode of time heating, promptly in the heating of ceramic disk bottom, thermal source is preferably 10-15 centimetre apart from the ceramic disk bottom, make thermal source neither directly contact the porcelain dish bottom, can make heat pass to the ceramic disk bottom equably again.The easy explosion of discontinuity because ceramic disk is heated, following heating ceramic dish must unsettledly make thermal source heat heating ceramic tray bottom equably, ceramic disk is very fragile again, strong point discontinuity is easy to the pressure break ceramic disk, therefore do supporting surface with wire netting, there is good elasticity to support ceramic disk equably, makes ceramic disk can bear very big pressure.Because the wire side size of wire netting can be unrestricted, following mode of heating heat time heating time and area are unrestricted, therefore can heat the ceramic disk of virtually any size and shape.About the immersion coating of ceramic card, picture paper (by heat shift ink by printer picture is printed on the color spray paper form), picture transition temperature, pressure (picture paper is adjacent to the porcelain dish face get final product) be identical with prior art, less than change.But press mode the present invention of picture paper to change, when exerting pressure promptly for picture paper to be adjacent to, be provided with the heatproof elastomeric material on the picture paper with ceramic card.Because the heatproof elastomeric material is softer, flexible, can make tabular that porcelain dish size and dimension with the institute baking adapts, also can get very tight when rough porcelain dish is exerted pressure with the porcelain dish surface pressure, the rough degree difference of porcelain dish, can adopt one or more layers heatproof elastomeric material to compress, no matter so the porcelain dish of what shape and size can obtain reasonable pressure, the image dish effect of baking is just very good.Because the temperature above the porcelain dish is controlled at 180-200 ℃, as long as the heatproof elastomeric material is this temperature of ability, can select materials such as silica-gel sponge plate, silica gel plate, rubber slab, felt for use, preferred silica-gel sponge plate, its heat resisting temperature is below 250 ℃, because of thermal source does not directly contact porcelain dish, thereby be not afraid of and burn out the silica-gel sponge plate.On the heatproof elastomeric material, press the correspondingly pressure plare of size shape,, provide certain pressure that picture paper and ceramic card are adjacent to when picture is heated, be convenient to picture is transferred on the ceramic disk as iron plate or other ponderable plate.Can add leading screw and withstand on iron plate adjusted pressure, because the different needed pressure differences of the size of porcelain dish, shape, regulate than being easier to leading screw and to control.
Thermal source of the present invention preferably adopts electrical heating elements such as heating wire or electrothermal tube.
Advantage of the present invention:
1, energy long-time heating work, homogeneous heating can not burn out the silica-gel sponge plate;
2, can the baking Any shape and the ceramic disk of size, can the rough ceramic disk of baking;
3, ceramic disk is heated evenly, and is difficult for explosion.
