The natural-travertine-imitated porcelain tile overcomes the defect that strength of a travertine porcelain tile is greatly lowered due to uneven stress distribution caused by holes, attractiveness of the appearance of the travertine porcelain tile is maintained, and the natural-travertine-imitated porcelain tile is a high-strength travertine porcelain tile which is more suitable for buildings.
Description
Technical field
The present invention relates to ceramic tile and manufacture field, relate in particular to a kind of natural cavity stone imitation ceramic tile.
Background technology
Architectural pottery requires to have certain mechanical strength, and part building ceramics requires there is higher mechanical strength, to meet stressed service condition and processing request.Floor tile just requires to have higher mechanical strength, as compressive strength.The mechanical strength of floor tile depends mainly on material, structure, simultaneously relevant to its process.Ceramic material mechanical strength is less, substantially is not used for doing floor tile, and floor tile is often selected porcelain or Shi material, and with respect to ceramic material, the mechanical strength of porcelain or Shi material is high; Configuration aspects depends primarily on ceramic effect, floor tile for example, adopt fine and close stacked mode intensity just high than individual layer, and there is relation with size, for example 600 be multiplied by 600,800 and be multiplied by 800 or 1000 ceramic tiles that are multiplied by 1000 specifications, intensity is separately different, along with the raising of production technology, in the situation that meeting requirement of strength, it is large that the ceramic tile dimension that ceramic tile manufacturer produces just progressively becomes; The change of architectural pottery manufacturing condition (as maximum sintering temperature, temperature retention time, underburnt or burning etc.) is fairly obvious on the impact of floor tile mechanical strength, and therefore, intensity is also the important indicator of check current technology situation and product homogeneity.
So-called compressive strength, that is, material section is compressed (extruding) power effect and damaged maximum stress is called compressive strength, take MPa as unit representation.During test, require the parallel compression face nonparallelism of the samples such as floor tile two to be less than 0.1mm/cm, non-perpendicularity degree is less than 0.2mm/cm, and obvious crackle and other defect are forbidden to have in surface, and the compressive strength of ceramic tile can record with omnipotent material section testing machine.
Certainly, when the mechanical strength of general ceramic material is discussed, often will thoroughly discuss the chemical bond of material molecule, as covalency key or ion key material have larger hardness and intensity, and molecule key mechanical strength is often less.Using fracture strength (modulus of rupture) and as the mechanical strength of building ceramic tiles, detect index, regulation: Imitation Rock Porcelain Tiles fracture strength is not less than 35MPa in GB GB/T4100.1-2006; Shi porcelain Ceramic Tiles modulus of rupture average is not less than 30MPa; Thin Shi matter brick modulus of rupture average is not less than 22MPa; Shi matter brick modulus of rupture average is not less than 18MPa; The modulus of rupture average of pottery brick is not less than 15MPa.
In the ceramic tile of a kind of natural cavity stone imitation occurring at present, by special material and processing technology, can form and be similar to the hole stone texture structure that natural cavity stone is the same, can be used for substituting natural cavity stone as constructional materials.
In natural travertine stone-imitated tile, can be divided into two kinds, a kind of have a true hole, ceramic tile deliberately generates hole in process of production, for example adopt some to be heated and produce gas material as a part for fabric, the material generation gas that is heated when firing, thus gas distributes the hole on surface from fabric.This natural travertine stone-imitated tile and natural cavity stone are more approaching.Another natural travertine stone-imitated tile, on the basis of the first, use transparency material to fill the hole producing, thereby form a kind of hole that appears to have, but touch up the ceramic tile that there is no hole sensation, the benefit of this ceramic tile is, can be used as ground tile paving, and because hole is filled, can not shelter evil people and countenance evil practices, convenient for cleaning, the while has retained again the natural aesthetic feeling of hole stone.
At present upper market has above-mentioned two kinds of ceramic tiles selling, but in actual use, natural travertine stone-imitated tile is in building, especially the use aspect floor tile, a lot of places not as people's will have been there are, for example compressive strength a little less than, in internal construction due to natural travertine stone-imitated tile, there is hole, no matter whether this hole fills, it is uneven that the existence of hole makes ceramic tile on three-dimensional thickness, because the distribution of hole is random, therefore the existence of hole is also random to the stress influence of monoblock ceramic tile, the intensity of each piece ceramic tile of producing is also random, usually easily there is the ceramic tile insufficient strength of producing, cannot be for building central or transporting, in use procedure, there is the situation of fracture.
Summary of the invention
The object of the invention is to solve the problems such as ceramic tile insufficient strength and propose a kind of natural cavity stone imitation ceramic tile.
For reaching this object, the present invention by the following technical solutions:
