Modulus of Rupture(MOR )- allowable bending strength of a tiles
Breaking Strength - strength of a tile to withstand without rupture
Crazing Resistance : rupture of glaze in the form of hair line crack due to difference in Dilatometer fit between body & Glaze surface
Abrasive resistance : the ability of a tile to resist surface wear caused by flat rubbing contact with another material ( abrasive particle).
frost resistance : the ability of ceramic tile to withstand freeze conditions with minimal effect. It is dependent on the tile's porosity and water absorption levels.

• The GVT means Glazed vitrified tiles. This type of
tiles are also made from the blend of different clays and
minerals like feldspar and quartz. This may be called in
another name like Gres Porcelain tile The word "grès"
means that the body of the tile is fired at 1200 degrees,
that makes it compact hard, and vitrified.
•Nitco ‘s brand name for GVT is NATUROC,
TRULIFE & MAGNIFIED.
•The top Surface will be decorated with the Imported
glaze and different types of printing like flat , roto or
digital depending on the nature of the product.
•The surface of the tile may be varying from the Stone
crest to Satin finish.
•The tiles may have the variation in shade to enhance the
natural look of the natural stone.
•This makes It highly resistant to moisture, staining and
wear.

Pop-UP/Buckling of Floor
![Page 21: Nitco techical and product knowlege of tiles ppt](https://reader031.fdocuments.us/reader031/viewer/2022021416/5a6d7cae7f8b9ade418b580f/html5/thumbnails/21.jpg)
Reason :-
Tiles may pop-up/Buckle either one of the following reason.Development of stress due to moisture expansion of tiles.Low Quality of adhesive/cement which cause of low bonding strength to tiles.Poor Workmanship of tiles laying.
Solution :-
Need to leave at least 1mm gap between tiles. Selection of right quality and right proportion of cement/adhesive.Allow the bed tiled floor for at least 3 days for complete setting of tiles. Avoid walking over the tiles during the period.
![Page 22: Nitco techical and product knowlege of tiles ppt](https://reader031.fdocuments.us/reader031/viewer/2022021416/5a6d7cae7f8b9ade418b580f/html5/thumbnails/22.jpg)
Stains
Reason :- Usage of Poor cleaning of tiles with Lizol / Klinol etc (Very mild germ cleaner chemicals)
Solution :- Suggest to clean the tiles with Tiles Cleaner viz. Bal Endura/Laticrete/Roff tiles Cleaner.
![Page 23: Nitco techical and product knowlege of tiles ppt](https://reader031.fdocuments.us/reader031/viewer/2022021416/5a6d7cae7f8b9ade418b580f/html5/thumbnails/23.jpg)
Crazing
Reason :- Difference in thermal expansion of body and glaze.
Solution :- Replacement of tile with fresh one if laid within 6 month of Nitco billing.
![Page 24: Nitco techical and product knowlege of tiles ppt](https://reader031.fdocuments.us/reader031/viewer/2022021416/5a6d7cae7f8b9ade418b580f/html5/thumbnails/24.jpg)
Loss of Gloss
Reason :- Had cleaned the tiles with strong chemicals result that the shining /polishing get off.
Suggestion :- Replacement of tile with fresh one. (Not from the NITCO as this not a manufacturing complaints. Its purely Application Problem).

Advantages of Using Spacers
• It will help the tile to get fix for long time and protect the tile from deboning & Pop-up• It increase the aesthetic look .•The Gaps should be filled with Epoxy Grout which is Having Several advantages A. Anti Bacterial
B. Anti Dust C. Anti Corrosive D. Leak Proof

Nano Coating Machine and its Purpose• Nano liquid is a special type of liquid which due to its small
particle size enters in to the Micro pores of the tile surface and after that it expands and cover the hole. This process leads to increase the glossiness of the tile as well as it imparts the anti stain property in the tile. The Photo graph of the Nano Application machine is as follows.
Moving Roller for even distribution
Rotating assembly
The Pipe through which the nano liquid is coming and it falls on the Moving Roller which is touching the tile surface and nano liquid gets distributed evenly on the tile surface.

Advantage of our Vitrified Over Gujarat market
Having More strength than the local vitrified tiles our tile is having the strength( MOR) of > 40N / mm2.
Having high glossiness due to firing at the high temp of around 12200c and polishing with the 48 head polishing machine with imported Grit. Our Glossiness for the platinum product is more than 94.
We are using the Imported Nano liquid for final finish so more Durable.
Definition of printing is also more due to printing with Sharp imported squeeze Rubber.
Water absorption (<0.07 %) is also less than that of the Gujarat product due to maturing the tile in such a high temp of 12200 C
Body brightness is also more than that of the local vitrified tiles because of using the high grade raw material for production.
The Body impurities is also less than the local Vitrified tiles because of using the strong Magnet at the tile of Slip preparation.
