In the Chinese food hygiene shop, in addition to its beauty and appetite, paying attention to the quality and efficiency of the product is very important. The most important qualitative and functional features to be taken into consideration when purchasing are:

• Glaze surface

The surface of the glaze is good, if it is placed under sufficient light, it is perfectly smooth and even, without wave and any tidiness, tangles or tangles. The glaze, which lacks a smooth surface, will be scratch-resistant, and after hard use it will be hard to clean.

• Glaze white

Chinese manufactured sanitary products in Iran are divided into white and white glacial white whites. Which is usually the current market

• Glaze transparency

The glaze transparency brings out the luminance and beauty of the piece, which depends on the use of high quality materials and cooking conditions. Since the reflectivity of an object is a good criterion for segmental transparency; the degree of transparency of the glaze is accurately measured by the amount of light reflected on the piece. Also, if different products of Chinese sanitary are under sufficient light, their glaze transparency is comparable to that of the normal eye.

• Cracking on the glaze

When buying a piece, you need to check all its angles and ensure that there is no malfunction, because even a very small cracks may even progress in time and ultimately break the piece.

• There are very fine cracks (hair) on the glaze

These hairy cracks are often not visible to the normal eye, and can only be detected by drawing nails on the glaze surface. These cracks are in the form of long, long, or spider-shaped cracks that occur due to thermal shock or non-compliance of the coefficient of thermal expansion of the body and glaze.

• Water absorption rate

According to international standards, the water absorption for a piece of Chinese must be less than half a percent. This feature is especially important for Asian and Pacific toilets because it is in direct contact with contamination and, if the amount of water absorption is high, it causes accumulation of contamination, bad odor and, consequently, the creation of an unsafe environment. It may even be due to the absorption of water and the expansion of the body in cracks and break through. One of the easiest methods that can relatively compare the absorbance of coconut water is to squeeze a drop of water on the undamaged part of the body and compare the penetration rate of the body in the body. The high rate of water penetration in the body indicates the high rate of water absorption, and this piece is not a good choice.

• The complexity of the parts

This defect is caused by the use of inert materials and inappropriate baking, and the way of detecting it is to look at the piece from different angles. A good Chinese health piece should be perfectly symmetrical. The complexity of the toilets causes problems in the installation and operation of the toilets, as well as preventing the correct placement of wipes on the cabinet or base. Moreover, the installation of other products will also be quite visible and may cause water loss and deposition of mass and salts in some products.

•  Drooping parts

When looking at a piece, all the pieces of the piece must be parallel. Dropping the piece, while creating an inappropriate appearance, can also have a detrimental effect on segment performance. Also, any deviation in the smooth lines of the piece can also indicate a defect in the product.

• Needle hole

In sanitary Chinese products, needle puncture is one of the most common defects, which is a very fine and impermeable needle hole on the surface of the glaze, resulting in loss of transparency and napping, as well as the main component of mass deposition in the piece.

• Surface contamination

Sometimes black, green or impurities can be observed on the surface of the glaze, which reduces the apparent quality of the piece and, in the latter case (impurities), can lead to accumulation of contaminants and mass deposition during consumption.

• Hygiene parts

Since the main ingredient in the health of the piece is its glaze; when shopping, note that more points of the piece are glazed. It’s better to have glazed ones even in places that are not exposed (like the edge of the watershed of Iranian and Western toilets). The sanitary glazing has an optimal baking and glass structure. To detect the relative property of this property, you can drag a whiteboard pencil or marker and then remove it with a cloth. If the stain is cleared without leaving any traces, it indicates the level of hygiene of the glaze surface.

• Ease of installation and accessories

All necessary accessories, such as pipes and fittings, bolts, nuts, washers, and also an installation guide are essential.

• After-sales service

Proper installation of the product is one of the factors affecting its performance and beauty that should be done by a skilled person and on behalf of the manufacturer or its agent. Also, the manufacturer’s response to any technical malfunction or functional failure of the product and, if necessary, to replace it with a healthy piece, is the criteria for selecting the product.

• suitable packaging

Chinese products are crisp and fragile, and therefore their packaging should be such that they can see the least damage during transportation, especially if it can cause cracks in the piece that can not be seen when buying and installing and which over time will cause Break it up.

• Model variation

The high variety of manufacturer’s models increases the power of choosing customers with different interests.
