Embodiment
Below in conjunction with embodiment, the invention will be further described.
A kind of working method of artistic ceramic tile is at first carried out raw material screening, removes impurity wherein.The raw material that screening is good adds the tamanori of corresponding proportion according to composition, grind and make slip, when the viscosity of slip reaches 30-35 handkerchief second, fineness reaches the 230-270 order, the best is 250 orders, tail over and be 3.5-4%, can put mill when proportion reaches 1.58-1.6, screen with 80 purpose sieves when putting mill, go into the pond to prevent big particle, screening back slip is introduced into conical tank, goes into the stirring that does not stop with agitator behind the pond, precipitation occurs to prevent slip.The slip that stirs is sent into moisture eliminator oven dry, makes slip be converted into spherical material powder, and expecting to should be difference according to month by the water ratio of powder this moment, to be decided to be the 2-6 month be 6.2-4.7%; The 7-10 month is 6.0-6.8%; The 11-1 month is 5.8-6.0%, and grain composition is 15-20% according to standard sub-sieve order number for greater than 40 orders the time; During the 40-60 order 65-75%; Be below 10% during less than 60 orders,, be difficult for the problem of the demoulding to prevent the sticking to mould tool.After making, powder changes press over to so that be pressed into base substrate, its operation be cloth (powder of variable grain size is evenly added in the model) three-dimensional repeatedly in the pressurization mould to powder by light to heavily carrying out at least five compression moulding, molding blank is ejected from model, connect base, carry out the arrangement of base shape.Used mould has the pattern and/or the literal of characters cut in relief and/or characters cut in intaglio in compression moulding, and has higher smooth finish, geometric accuracy, dimensional precision particularly will have high surface hardness, so that increase resistance to abrasion, the demoulding is easy, on the mould projection the lines flow smoothly, full, sunk part then should be level and smooth, lucid and lively, its chi difference requires to be positive and negative 40.Three-dimensional repeatedly pressurization refers to ceramic tile is pressurizeed on a plurality of directions, is undertaken by the moulding process that gently reduces pressure again to heavy supercharging gradually according at least five times during pressurization.Adopt this process be because, spheroidal particle is the artificial granulation, more much bigger than the solid particulate in the actual slip, wherein be wrapped in many gases, when compacting wherein gas and the gas that himself contains to discharge, so should not overexert when just beginning to pressurize, otherwise base substrate is cracked.Along with the gas in the loose powder of the increase of pressure is discharged from, solid particulate is compressed to be drawn close, and blank forms base substrate.Repeatedly add the base substrate that is pressed into three-dimensional, different sites is stressed balanced, and each position density of base substrate is even, not easy to crack, when moulding pressure is increased to the degree that can make spheroidal particle distortion and fracture, the particulate corner angle flatten, the space continues to fill, and blank density is further enhanced.Then, decompression is held the pressure time with prolongation, helps the discharge of base substrate gas, also is beneficial to the demoulding.
The base substrate of making then is admitted to biscuit kiln.Because of base substrate of the present invention is thicker, and uneven, in uneven thickness, so biscuiting employing low temperature unglazed mode, whole firing period was advisable with 40 minutes between 35-45 minute.Base substrate passes through low-temperature prewarming band-oxygenolysis band-thermal zone-cooling zone four-stage successively during biscuiting.And low-temperature prewarming band and thermal zone lengthening, cooling zone shortens, to improve yield rate and green body quality.The temperature of low-temperature prewarming band should be advisable with 400 degrees centigrade between 350-450 degree centigrade.The oxygenolysis band mainly is to discharge crystal water, allows organism and carbon element oxide compound and carbonate decomposition.Thermal zone temperature is advisable with 900 degrees centigrade between 800-950 degree centigrade, both guaranteed rough base substrate more volatile organic compounds fully, make base substrate indeformable again.Cooling zone should not adopt chilling, in order to avoid cause be full of cracks.
Glazing process in the glaze Wiring technology is humidification-execute ground-coat enamel-execute cover-coat enamel-deburring-protective layer.When executing cover-coat enamel and executing ground-coat enamel, should in glaze, add an amount of tamanori, stablizer and foam preventer, make two glaze layers on base substrate, form glazed body special combination layer, and then will be coated on the ceramic tile by the coating that 92% aluminum oxide, 8% kaolin, 1% tackifier are formed, form protective layer, to prevent to occur when next step glaze firing the phenomenon of distortion or roll banding.
Ceramic tile after the glazing is sent into glost kiln, also comprise low-temperature prewarming band-thermal zone-cooling zone in this process, different with aforementioned biscuiting is the mode that it has adopted grand feu, its thermal zone temperature is between 1100-1200 degree centigrade, be advisable with 1150 degrees centigrade, the whole firing time is 85-95 minute, is advisable with 90 minutes.Ceramic tile after the glaze firing is used the over-quenching water cooling, carries out trim process with deflasher again.This moment, ceramic tile also need be dried, so that the packing warehouse-in.
