Abstract

A method for producing ceramic tiles with natural sections includes squeezing out clay material by screw vacuum extruder, cutting to obtain block blanks, drying until water content is 1-10%, impacting the side of blanks to crack them in stressed direction, so forming natural sections, and high-temp firing. Its advantages are different and natural sections, lifelike effect, and the quality, lustre and grains similar to natural rock.

Description

A kind of forming method of ceramic tiles with natural section

The present invention relates to a kind of forming method of Ceramic Tiles, particularly have the forming method of the ceramic decorative brick of stone material natural section effect.

At present, the building decoration ceramic material is for pursuing natural stype, in the manufacture process of ceramic product different processing being carried out on its surface handles, as forming natural decorative effects such as bag, flowing water line, wood grain by technologies such as mould compacting or glazings, but these processing, processing method all have fairly obvious artifact, make concave-convex surface variation dullness, the texture texture of ceramic product not true to nature, stiff, can not embody natural stype original, true to nature.

The objective of the invention is to overcome the weak point of prior art, a kind of concave-convex surface fluctuations nature is provided, texture is strong, color and luster, texture and stone material section approximate ceramic tiles with natural section forming method true to nature.

The objective of the invention is to be achieved through the following technical solutions: a kind of forming method of ceramic tiles with natural section, make pug with general ceramic raw material, make special equipment with the paired bump cutter of arranging in opposite directions on spiral vacuum-extruder and the same horizontal plane; Pug squeezes out, cuts into block moulded pottery not yet put in a kiln to bake by the spiral vacuum-extruder; Block moulded pottery not yet put in a kiln to bake is dried to moisture content 1-10%; Dry block moulded pottery not yet put in a kiln to bake is placed between the bump cutter, and by the side of bump cutter impact block shape moulded pottery not yet put in a kiln to bake, block moulded pottery not yet put in a kiln to bake to split by force direction, forms two adobes with plane of disruption up and down along quilt bump place under the effect of clashing into equilibrant force in opposite directions; At last with hard-fired ware brick in the adobe.Further, the preferably flat cutter of bump cutter, and its length should be not less than 2/3 of block moulded pottery not yet put in a kiln to bake total length.

The Ceramic Tiles that adopts said method to make, its surperficial section effect is true to nature, concavo-convex fluctuating nature, and moulding is ever-changing, no matter extremely similar at the section of all riving to lithotome on the texture, on the color and luster, on the texture, and have the anti-advantage of freezing etc. of intensity height, protection against the tide, corrosion resistant.

Fig. 7 is the schematic diagram that block moulded pottery not yet put in a kiln to bake is separated into two adobes up and down.

Below in conjunction with drawings and Examples content of the present invention is described further.

Embodiment one:

Referring to Fig. 1-Fig. 7, present embodiment is made raw material with yellow mud, be prepared into pug by pugging, pug is dropped into spiral vacuum-extruder 1, extrude and cut into the block moulded pottery not yet put in a kiln to bake 2 that specification is 264mm * 44mm * 44mm by spiral vacuum-extruder 1, above-mentioned block moulded pottery not yet put in a kiln to bake 2 is put in drying kiln for drying, block moulded pottery not yet put in a kiln to bake 2 kiln discharge moisture content are 9%, then block moulded pottery not yet put in a kiln to bake 2 is placed on the pipeline 3, pipeline 3 both sides are furnished with the flat cutter 4 of a pair of bump usefulness in opposite directions, 5, two flat cutters 4 wherein, 5 length is 300mm, arrange in opposite directions on the same horizontal plane, flat cutter 4 is fixed, and flat cutter 5 is movable (as Fig. 2, shown in 3), when block moulded pottery not yet put in a kiln to bake 2 is in flat cutter 4, in the time of between 5, flat cutter 5 is rapidly to block moulded pottery not yet put in a kiln to bake 2 bumps, like this,

flat cutter

4,5 the equilibrant force of bump in opposite directions acts on block moulded pottery not yet put in a kiln to bake 2 two sides center lines (as Fig. 4, shown in 5), flat then cutter 5 is backed out rapidly, make block moulded pottery not yet put in a kiln to bake 2 be impacted the back along by the bump place to split (as shown in Figure 6) by force direction, thereby form two adobes 6 up and down with nature plane of disruption, 7 (as shown in Figure 7).At last adobe 6,7 being put into tunnel kiln high temperature through about 1100 ℃ burns till.Certainly, present embodiment is because the moisture content of block moulded pottery not yet put in a kiln to bake 2 is 9%, and the plasticity of block moulded pottery not yet put in a kiln to bake is bigger, can occur clashing into dark excessively, the phenomenon such as incomplete of splitting of trace during

flat cutter

4,5 bumps, and yield rate is low.

Embodiment two:

The forming method of present embodiment and embodiment one are roughly the same, having difference with three kinds of white claies, yellow mud, red soil burns till the feedstock production of color and becomes pug, it is 4% that block moulded pottery not yet put in a kiln to bake is dried to moisture content, the length of two flat cutters is 264mm, identical with block moulded pottery not yet put in a kiln to bake length, burn till the ceramic tiles with natural section with multiple secondary colour at last, present embodiment is because the moisture content of block moulded pottery not yet put in a kiln to bake is moderate, and bump back section splits fully, bump place lines are neat, the yield rate height.

Embodiment three:

The forming method of present embodiment and embodiment one are roughly the same, become pug with yellow mud, stone flour as feedstock production, the moisture content of block moulded pottery not yet put in a kiln to bake is 1.5%, and two flat cutters of bump usefulness are move toward one another simultaneously, and the length of two flat cutters is 250mm, length less than block moulded pottery not yet put in a kiln to bake, present embodiment can burn till the Ceramic Tiles with natural section equally, and just because the moisture content of block moulded pottery not yet put in a kiln to bake is very low, moulded pottery not yet put in a kiln to bake intensity is big, the meeting that bump back section has to around split, yield rate is lower.

Certainly, the specification of the block moulded pottery not yet put in a kiln to bake of the present invention is also unspecific, as long as change the extrusion size of spiral vacuum-extruder and the length of bump cutter, just can be used for producing the ceramic tiles with natural section of different size size.

Claims

1, a kind of forming method of ceramic tiles with natural section is characterized in that:

A. make pug with general ceramic raw material, make special equipment with the paired bump cutter of arranging in opposite directions on spiral vacuum-extruder and the same horizontal plane;

B. pug squeezes out, cuts into block moulded pottery not yet put in a kiln to bake by the spiral vacuum-extruder;

C. block moulded pottery not yet put in a kiln to bake is dried to moisture content 1-10%;

D. Gan Zao block moulded pottery not yet put in a kiln to bake is placed between the bump cutter, and by the side of bump cutter impact block shape moulded pottery not yet put in a kiln to bake, block moulded pottery not yet put in a kiln to bake to split by force direction, forms two adobes with plane of disruption up and down along quilt bump place under the effect of clashing into equilibrant force in opposite directions;

E. at last with hard-fired ware brick in the adobe.

2, forming method according to claim 1 it is characterized in that clashing into the preferably flat cutter of cutter, and its length should be not less than 2/3 of block moulded pottery not yet put in a kiln to bake total length.
