In addition, according to standard GB/T/T3810.14-2006, to ceramic antifouling property testing method test, the product antifouling property is divided into A, B, C, tetra-ranks of D, and wherein the A level is best, and the D level is the poorest.The product that adopts the present embodiment technique to make is soil pick-up not, and antifouling property reaches the A level.
embodiment six
Adopt the resulting super spar product of above-described embodiment one to embodiment five making directly to be layered on flow of the people large, on the passageway of office of factory, with microlite, common polished tile, common full throwing glaze compares acquired results and is: four kinds of products of paving simultaneously, and after the microlite first quarter moon, there are a lot of tiny cuts on surface, and large cut is arranged, and the full wafer brick changes so much that one loses one's identity; Common full throwing glaze also has a lot of tiny cuts after January, surface is fuzzy, loses original texture; The super spar of product of the present invention is after June, and surface only has several tiny cuts, and under glaze, the pattern lines is clear, glittering and translucent equally, glossiness during as just paving, reach 98 degree, also have obvious mirror effect; The tiny cut of common polished tile is less, but, because its glossiness just only had 80 degree left and right originally, therefore mirror effect is poor, and there is no good texture.
To sum up, the present invention had both solved that microlite fastness to rubbing in the prior art is poor, the problem of processing difficulties, also solved full throwing glaze soil pick-up, easily show-through, the brick face uneven and the defects such as water ripples that cause.The super spar product that utilizes the present invention to produce, have a microlite penetrating beautiful, smooth as mirror, soil pick-up not fully, and entirely throw the frivolous advantage such as wear-resisting of glaze.
Obviously, the above embodiment of the present invention is only for example of the present invention clearly is described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.All any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in the protection domain of the claims in the present invention.
