Is there any difference from ceramic and porcelain?
It differs at water absorbability. The one with less 0.5% is porcelain, the one with more 10% is ceramic, the one with middle between both is semi-ceramic.

Which tiles are porcelain materials? Which tiles are ceramic materials?
The polished tiles, non-glazed brocade tiles, a majority of sanitaryware we saw daily is ceramic, water absorbability E≤0.5% ； archaize tile, small flooring tiles(terra creep wall) , crystal tile , Wear-resisting brick , matt tiles are semi-ceramic tile, water absorbability, 0.5%<E≤10% ； porcelain chips , ceramic brick , decoration tile , glass products are normally ceramic , water absorbability E>10% 。

What is water absorbability?
Water absorbability is the ratio of how much water ceramic air hole absorb.

How doe the ceramic wall and flooring brick classify?
According to usage, it sorts internal wall brick, external wall brick and flooring brick.
According to material:Porcelain--- euphotic, fine rupture appearance
Semi-ceramic brick—bad euphotic, high intensity mechanism, stone styled rupture appearance;
Ceramic brick—no euphotic, low intensity mechanism, rough rupture appearance
According to moulding, it sorts dry-pressure, mold, plasm injection.

What varieties are involved with ceramic wall and floor brick?
Glazed internal wall brick: tile , flower chip , listello ；
Ceramic external wall brick : glazing tile, no-glazing tile, flock tile, brocade tile ；

Could wall tile be installed on the bathroom floor?
Wall tile (tile) could not used on the floor. Because the ceramic tile is ceramic material, mechanism intensity is very low, it is easy to break by pressure on the floor; The toilet floor is moist for long time, the ceramic tiles are easy to rupture by expandability;on other side, the glazing face of tiles is not slide-proof.

What is the difference between the high grade and 1 st grade products(quality passed) ?
The high grade and 1 st grade products are both quality passed, but the daily used product's function would not be affected. It mainly showed the difference on appearance quality and distortion permission range, such as appearance spots, pinhole.

Is there any shortage for high grade product?
Because ceramic is made of various kinds of raw materials through high temperature firing, it is impossible to prevent from all defects such as impurity, distortion.The national standard allows to exist certain defect too. Such as surface quality, the polished brick high-class product stipulates that it has no defect to be observed rating at 95% at least on the surface vertically from 0.8m distant place that there are 95% of the bricks at least.

Are bricks made of underground mud?
Main raw materials that the wall ceramic tile produces are: Kaolin and chemical materials , etc., kaolin mainly include sand , stone powder , dark mud and white mud ,etc.,chemical materials mainly include chromogenic material, water-reducing medicament,etc. . The popular statement is that brick is made of mud, but it is not the general mud, it should reach certain chemical compositions, has good quality and becomes ideal raw materials steadily.

The red brick is a pottery brick, the white brick is a porcelain brick, is the red brick not so good as the white brick?
This kind of statement is not scientific. It was the content of iron, titanium oxide formed base body that determined base body color, more darker the color fired, the higher content higher, it determines base of body only, will not influent the quality of the brick. To know the factor influent inherent quality of brick is to watch its sintering degree , the brick in high quality is the one that has been really " burnt completely ".

Why will the polished brick be waxed or spreaded the antipollution pharmaceutical?
Polished brick waxed can be better protected, prevents from strike , friction, damage when constructing; Glossiness can be increased on the brick after wax remove ; the most important thing is that we can pack the air vent on the brick surface , make the dirt not fill in the air vent, easy to clean at daily time.

When polished brick is installed on external wall, why is it dry hang ?
Mainly it is considered safety. Polished brick has low water absorbability, smooth back, it is difficult to glue firm with cement sand liquid; On the other hand, it is very big and heavy and easy to fall off.

Compared with crystal brick, matt brick, which kind of slip resistance result is better?
The matt brick slip resistance result is better, because it is generally all designed with the slip resistance

Polished brick , crystal brick, matt brick, which slip resistance result is better? Why?
The slip resistance result of polished brick is best, because it is better to absorb after polished.
