The ground glaze layer of adobe, which is thrown to cut and polish, has smooth surface, reduces influence of the adobe to glaze paint expressive force, further
Reduce the cost of high request ceramic tile.Meanwhile so that dry method powder has more application spaces.Adobe is applied just to carry out after ground coat enamel throwing and be cut
Be conducive to reduce and throw the amount of cutting, reduces production cost.The ground glaze layer that moisture content is 6~9% is convenient for throwing and cut, and high throw of moisture is cut
When be easy to paste abrasive band, moisture is low to be thrown and flat or jettisoning is thrown in the place of protrusion when cutting can form one again
Pit, brick face are rough.
The powder particle size that dry method powder obtains is different, and after being suppressed into adobe, the concave-convex surface degree of adobe is 0.1~
0.5mm is still difficult to cover the bumps on surface after ground coat enamel is applied in adobe, under the glaze volume, applies the concave-convex surface journey of ground coat enamel adobe
Degree throws the amount of cutting in 0.05~0.2mm in 0.05~0.3mm.This is because abrasive band constantly carries out adobe surface when throwing is cut
Grinding, moisture is constantly uniformly evaporated from inside to outside, and grinding waste material part is received in the tiny recess portion on adobe surface, then by
Abrasive band pressurization makes the tiny recessed carry out portion cut with throwing constantly be filled and led up compacting.Therefore, when throwing the amount of cutting less than concavo-convex amount, brick
Base surface still is able to reach good flatness and smoothness, cuts efficiency so as to improve throwing, reduces abrasive band loss and saves
Energy consumption.By throwing the setting for the amount of cutting to ground coat enamel applied amount and to ground glaze layer, in the case where endless complete hiding adobe concave-convex surface
Throw and cut, ground coat enamel applied amount and the throwing amount of cutting are coordinated to reduce production cost in a zone of reasonableness.
Further, the moisture content in step (1) when adobe compression moulding is 6~9%.Adobe in this aqueous range
Not only there is enough intensity, but also be convenient for throwing and cut, the brick face after the throwing made is cut is smooth.It is straight after adobe compression moulding
It taps into row and applies ground coat enamel operation, alternatively, carrying out applying ground coat enamel operation after the brick bat drying to moisture content is 1~3%.Moisture content 6~
9% adobe has enough intensity throw and cut, when ground glaze layer local thickness, which is less than, throws the amount of cutting, adobe and ground glaze layer water tariff collection
Unanimously, it is more advantageous to form smooth flat.1~3% adobe of moisture content has higher intensity, and can have increasing applies ground coat enamel
Amount when throwing is cut, only throw to ground glaze layer and cuts the adobe that can be obtained smooth surface.
Further, in step (2), to apply ground coat enamel adobe carry out throw cut before, using high temperature lamps to apply ground coat enamel adobe into

Side.The baking time of adobe is 5~7min, and the baking temperature control of high temperature lamps is at 105.3~110.7 DEG C, the edge of adobe
Distance controlling with high temperature lamps is in 10~12cm.Under this Flue curing parameter, 1/3 thickness moisture content of adobe upper layer reaches 3~
4%.
It toasts before throwing is cut to applying ground coat enamel adobe, ground coat enamel adobe layer humidity is applied in reduction.When belt sanding humidity compared with
Low when applying ground coat enamel adobe surface layer, the throwing for applying ground coat enamel adobe surface layer cuts that waste granules are small, throw after cutting to apply ground coat enamel adobe surface flat
Whole degree is more preferable.When applying ground coat enamel adobe after drying steps, surface smoothness is unaffected.Moreover, lesser waste granules
Be conducive to filling and apply the tiny recess portion on ground coat enamel adobe surface, cuts energy consumption to applying ground coat enamel adobe baking and helping to reduce to throw.
After applying ground coat enamel adobe baking, the moisture content of 1/3 thickness of ground coat enamel adobe upper layer is applied 3~4%, with sufficiently small
While hardness, there is preferable dry and comfortable degree, advantageously form the waste material of smaller particle, is also beneficial to waste material insertion and applies ground coat enamel adobe
The tiny recess portion on surface.It applies 1/3 thickness of ground coat enamel adobe upper layer to refer to, applies 1/3 thickness of ground coat enamel adobe entirety, the 1/3 thickness position
In the surface layer for applying ground coat enamel adobe.
The baking temperature of high temperature lamps is 105.3~110.7 DEG C.The baking temperature, which can satisfy, reduces adobe surface moisture
It is required that while be conducive to the moisture content inside adobe and uniformly distribute, which belongs to the lower temperature of high-temperature baking lamp, can
To save the energy.Adobe edge and the minimum distance of high temperature lamps are 10~12cm, have cured effect more evenly to adobe, favorably
It distributes in moisture is more uniform.
Further, in step (1), in the formula of adobe include 30%~45% bentonite, pressing unfired brick is most
Big pressure is 300~320Mpa, and the green strength after the completion of suppressing reaches 3~4Mpa.Bentonite, particularly Laiyang soil or
Person Tangxian County weak soil, there is more plasticity.In the granulation step of dry method powder, bentonite is less than as skin granulate material, fineness
600 mesh, other conventional blank raw materials are center particulate material, and centrophyten partial size is at least twice of partial size of skin granulate material, will
Skin granulate material and centrophyten material press 3~20:100 weight proportion is weighed, and is sent into pelletizer be humidified and be made
Grain obtains the solid powder wrapped up by skin granulate material after dry.After the solid powder pressing becomes adobe, between solid powder
Binding ability is strong, is conducive to the intensity for improving adobe.
Further, in step (1), when the humidification of dry method powder is granulated water spray, organic granular enhancing is added in water
Agent, additional amount 0.05%-0.2%, the maximum pressure of pressing unfired brick are 300~320Mpa, the green strength after the completion of suppressing
Reach 3~4Mpa.Specific organic granular reinforcing agent is polyacrylamide.
Further, the sand paper mesh number in abrasive band is 240~600 mesh, thus make to apply ground coat enamel adobe surface have it is enough smooth
Degree and smoothness.When throwing base machine throwing in abrasive band is cut, the linear velocity in abrasive band is 10~14m/min, and pulley speed is 670~1420r/
Min, the frequency that base machine is thrown in abrasive band is 21~28Hz.Adobe throwing is when cutting, and adjusts the throwing amount of cutting by adjusting the height in abrasive band, in advance
The height for setting abrasive band starts to cut the throwing of adobe, with the movement of adobe, works as brick when adobe edge is contacted with abrasive band
It completes to throw when base passes fully through abrasive band to cut.
Further, it is three groups that the abrasive band of base machine is thrown in abrasive band, and the mesh number in three groups of abrasive bands is 240 mesh, 320 mesh, 400 mesh, or
The mesh number in three groups of abrasive bands of person is that 320 mesh, 400 mesh, 600 mesh or the mesh number in three groups of abrasive bands are 400 mesh, 400 mesh, 600 mesh.It is logical
Three groups of abrasive bands of setting are crossed gradually adobe to be carried out throwing to cut reaching the throwing amount of cutting.The setting in multiple abrasive bands can not only to apply ground coat enamel brick
There are better smoothness and flatness in the surface of base, reduce the breakage of adobe, applies ground coat enamel moreover, it is also possible to reach the throwing amount of cutting and be less than
