1. High PH resistance and low water absorption, hard to oxidation and be polluted by media at normal temperature, etc.
2. Anti-Corrosive : Good anti-corrosive effect to the acid, warm chlorine brine, hydrochloric acid, sulfuric acid, nitric acid, etc., and to alkali of any concentration at room temperature except hydrofluoric and hot phosphoric acid.
3. Fire resistance: Ceramic tiles are completely fire-proof at any temperature. They will not burn nor fuel a fire. The surface will not alter, nor will it give off any toxic gases, smoke or fumes during a fire.
In addition to being fire-proof, tiles have also been found to provide protection for structural surfaces during fires.
4. Hygiene: The face of ceramic tiles will not retain liquids; absorb fumes, odors, or smoke. This allows for good hygiene. National Tiles are suited for any environment where hygiene is essential.
National Tiles Industrial Ceramic Tiles has such characteristics, high acid-resistant, strong mechanical properties, low water absorption. They are necessary anti-corrosion materials in sulfuric acid factory, chemical factory, fertilizer factory, Gas Company, vinyl on, dye, chemical fiber, pharmaceutical, etc... And they are ideal products for old factory exploiting, the new factory building, lowering production costs and improving economic efficiency.
National Tiles is Manufacturing Vitrified Tiles, which is made by baking fine minerals, at extreme high temperatures where the individual grains or particles melt and fuse make a vitreous surface. Thus creating a single mass making them extremely hard with low porosity.
|Water Absorption||Scratch Hardness||Breaking Strength||Resistance to Acids / Alkalis||Thickness %||Length & Width|
|International DIN Spec: 18166||For light color 3% For colored body<6%||5 on Moh's Scale||20 N/mm²||A AA||± 1.0%||± 1%|
|National Tiles||<3% <6%||6 -7 on Moh’s Scale||25 N/mm²||A AA||± 0.9%||± 0.6%|
v Straightness of sides and flatness of surface well within DIN specification No. 18166
v Resistance to House, Industrial and swimming pool Chemicals.
Due to the tremendous gains in technology in the ceramic tile industry over the past several years, manufacturers have been able to create looks that are truer to natural stone than ever before. These technological gains have been very positive for us all by creating new and innovative looks. They have also caused some difficulty since selling these types of tile takes a little more education than in days of old. In order to try to make things clearer and easier we have taken some information from the CTDA (Ceramic Tile Distributors Association) to clarify the situation with regards to shading.
The color shade and pattern of all tile varies to some degree from piece to piece and from production run to production run. In some tiles these are very slight (almost not noticeable) and in others they are very extreme (might look like different color tiles in the same box). Since this wide of a variety exists in shading today it is important for you to be educated about the tile you are selling and for you to educate your customer. Since our material is typically mid-high end products, shading tends to play a larger factor than in the lower end material
We have added these symbols to our images, which denotes one of the above levels. Since we have found that each person’s interpretation of the above information is different, you must use this as a loose guide. Also, within a series by the same manufacturer the variation level may change with lighter colors having less variation and darker ones showing more. When in doubt have your customer approve a box from the current shade.
V1 – Uniform Appearance
Differences among pieces from the same production run are minimal.
Clearly distinguishable differences in texture and/or pattern within similar colors
V3 – Moderate Variation
While the colors present on a single piece of tile will be indicative of the colors to be expected on the other tiles, the amount of colors on each piece may vary significantly.
V4 – Dramatic Variation
This tile resembles natural stone and may have extreme variations within a range of different colors. One tile can have totally different colors that are not present in others.
