We all use sanitary ware products frequently at home, workplace, mosques, schools, restaurants, hotels, etc. But we may not know the specifications of a good sanitary ware. This is a question that some customers often ask themselves when buying sanitary ware, and sometimes they buy a sanitary ware product without paying attention to its features. Therefore, in order to satisfy the compatriots as much as possible, some of the specifications necessary to choose the best product are introduced. In order to check the quality of sanitary porcelain products, they should be considered in terms of appearance and performance.
The sanitary porcelain products mainly include all kinds of fringe toilets, bidets, all kinds of vanities and pedestals, Iranian toilets, shower trays and all kinds of accessories.
The specifications that the customer should pay attention to when buying sanitary ware in terms of appearance are:
Glaze transparency : This glaze property, which is created by the use of high-quality materials and suitable baking conditions, makes the piece shine and beautify as much as possible. Its amount can be accurately measured from the amount of reflected light to the part. Also, if we place different parts under enough light, it can be compared and selected with the normal eye. The clarity of the reflected image of an object is a suitable measure for the transparency of the piece.
Glazed surface : A high-quality glazed surface is a surface that, when you look at it under sufficient light, is completely smooth, without waves and without roughness or palpable depressions and protrusions. Glaze that has these items is mainly anti-scale and is difficult to clean after repeated use.
Cracks on the body :When buying a piece, check all its angles and make sure there are no small cracks. Because the presence of even a very small crack may develop over time and cause the piece to break.
Very small (hairy) cracks on the glaze : these cracks are mostly not visible to the eye and can only be detected by drawing a nail on the surface of the glaze. These cracks can be in the form of continuous and long cracks or spider webs that occur due to thermal shock or the mismatch of the coefficient of thermal expansion of the body and glazing.
The amount of water absorption of sanitary porcelain: According to the international standard, the water absorption of a piece of sanitary porcelain should be less than 0.5%. This issue is especially important for ground and floor toilets, because they are in direct contact with waste and if their water absorption is high, it causes the accumulation of pollution, bad smell and creating an unsanitary environment. It is even possible that due to the absorption of water and the expansion of the body, it may cause the part to crack and break over time. One of the easiest methods that can relatively compare the water absorption of sanitary porcelain parts is to drop a drop of water on the unglazed part of the body and compare the rate of water penetration in the body. The high rate of water penetration inside the body indicates the high water absorption rate of the piece and this piece will not be a suitable choice for Iranian and French toilets.
Complexity of parts : This defect is caused by poor quality materials and improper cooking, and the way to recognize it is to look at the part from different angles. A piece of sanitary ware must be perfectly symmetrical. This defect for toilets prevents them from being placed correctly on the base or cabinet. Also, the complexity of a toilet causes problems in its installation and operation. This defect will be evident in the installation of other parts as well, and it may also cause stagnation of water and deposition of mass and salts in some parts.
Dropping of parts : when you look at the part, all the surfaces of the part should be parallel to each other. Sagging of the part, while creating an inappropriate appearance, can also have an adverse effect on the performance of the part. Also, creating any deviation in the smooth lines of the part can also indicate the existence of this defect.
Pinholes : Pinhole defects, which are one of the most common defects in sanitary porcelain products, are very small and visible pinholes on the surface of the glaze, which cause a loss of transparency and roughness, and are also the main factor in scaling of the piece. Surface pollution: Mainly on the surface of the glaze, contamination in the form of black, green or impurity spots may be observed. which reduces the appearance quality of the piece and in the latter case (impurity) can cause the accumulation of pollution and mass deposition during consumption.
Healthiness of parts : When buying, pay attention to choose a part that has more parts of it glazed. It is better that even the areas that are not visible are glazed (such as the draining edge of Iranian and foreign toilets). Because the glaze is the main factor in the hygiene of the piece, and it is a hygienic glaze that has optimal firing and maximum glass structure. To detect this property relatively, you can draw a pencil or whiteboard marker on it and then wipe it with a tissue. If it is removed without leaving any marks, it indicates the health of the glazed surface. Ease of installation and accessories: It is necessary to have all the necessary accessories, such as pipes and fittings, screws, nuts, washers, as well as clear instructions for installation.
After-sales service : The correct installation of the product is one of the factors affecting its performance and beauty, which should be done by a skilled person, on behalf of the manufacturer or its representative. Also, the manufacturer’s responsibility for any technical defect or failure or functional defect of the product and if necessary, replacing it with a healthy part, can be one of the criteria for product selection.
The performance of toilet bowls : A proper toilet bowl should evacuate the most mass from the bowl with the minimum amount of water, the minimum time, without sound, without secretion and with sufficient suction power. Therefore, when buying, ask the seller for an explanation of these specifications or look for them in the guide brochure.
suitable packaging : Porcelain pieces are fragile pieces and therefore their packaging should be in such a way that they are least damaged during transportation, especially because cracks may appear as a result of damage that were not observed during purchase and installation and delayed. cause the part to fail.
Innovation and more capabilities: In recent years, the Chinese Rose Sanitary Company has presented new designs to the market that have created more capabilities in parts and have been welcomed by consumers. Including the installation of the internal washing valve in the toilets and glazing of all parts in contact with water
Model variety : The high variety of production models of a manufacturer increases the choice of customers with different tastes
