Application of stone waterproof adhesive

Recently, Chinese ceramics for the first time the global collection of cartoon image, the media would greatly track. Ceramics is closely linked with the Chinese civilization, the history of ceramics is an important part of the history of Chinese civilization, in the early period of Emperor Yao has painted pottery. The history and development of ceramics, is too rich, too numerous, not repeat here here. Only on the following issues.

The relationship between tiles and ceramics:

According to the use of ceramic is mainly divided into three categories, one is the ceramics for daily use, such as bowls, dishes, tea sets, two. Crafts ceramics, such as vases, paintings, glass etc.. Three is the industrial ceramics, industrial ceramics and a variety of points, a part of building ceramic tiles only. We can see. Bohuazhuan itself belongs to the ceramic, it is the development of modern industrial technology of the newborn, but its blood relationship is quite complex, this study is very interesting.

According to historical records, Bohuazhuan is the origin of Italy and Spain, in 80s before the introduction of Chinese. Since the earliest Chinese for ceramic tiles and ceramic invention, is the offspring, but not like a direct descendant, mulatto. This point should be not at all surprising.

What is the tiles?

The definition of a lot of tiles, most can be summed up in the most compelling definition is: less than 0.5% of the rate of water absorption of ceramic tiles, tiles are in. The delimitation of water absorption rate, water absorption rate is less than 0.5% polished tiles. The lower water absorption, the texture is dense, the higher the hardness.

After the introduction of Chinese Bohuazhuan, after decades of development, the birth of.2000 in the manufacturing technology and practical application of rapid differential technology, Bohuazhuan opened the history of the revolution of a page, the original "flat" transition to a sense of hierarchy, have stereo feeling, can simulate natural stone stone. Belong to non renewable materials, and it is not easy too thin, and radioactive substances; and the tiles have not only the stone of perception, and has the advantages of high strength, safety and health, the cost is far lower than the stone, so in the hardcover industry, Bohuazhuan is rapidly replacing stone was used in the market.

Why wet paste tiles Konggu easy?

The rapid application of Bohuazhuan, time is too short, or by a large area in the recent years. Because people are accustomed to ordinary ceramic tile bonding method, at the beginning of the bonding tiles also according to bonding methods of ceramic tile construction, so some of the binder, poor water slurry feeding. The results showed that after a period of time, Bohuazhuan occurs Konggu, off phenomenon.

Bohuazhuan due to water absorption, high hardness, adhesive force of the adhesive materials are usually not up to the firm strength. In addition, with the change of temperature, the thermal strain between tiles and adhesive materials, when the strain stress concentration (usually focus on the interface between different materials produced) a strong destructive force, resulting in tiles Konggu. That is the back light Bohuazhuan once the hollowing.

How to prevent the hollowing tiles?

Bohuazhuan wet paste project, early prevention is far better than remedial. Once the hollowing, repair and maintenance is very troublesome, the cost is much higher than the initial installed cost, believe whenever friends encounter hollowing, must have a deep experience. So, can prevent the hollowing tiles?! when we fully understand the characteristics of tiles the learned new materials must use new technology and new bond bond materials, take the corresponding change, you will avoid the harm of hollowing tiles. At present, the construction technology of ceramic tile adhesive binder + ", is the most effective method of wet paste.

A stone, ceramic tile, waterproof adhesive was born in the background:

Ceramic tile, stone is building decoration materials of high-grade products. At present, there are mainly two kinds of ceramic tile, stone decoration method, dry hanging and wet paste. The dry hanging office business hall large general application or exterior space; and the wet paste is mainly used for internal decoration of various buildings. Hanging large occupied space, high cost, and the wet paste you need to solve two problems: one is the bond strength problem of the stone, is not well controlled, easy to hollowing; two is easy to produce white Chinese phenomenon, caused by stone discoloration, affect the appearance. Three tiles, stone will directly off and cause dangerous use of cement paste long time

Ceramic tile, stone has a capillary, without treatment will seepage. Stone forming factors of Bai Hua and water spots, large quantities of water and alkaline metal ions are produced by Bai Hua, which plays the role of water to take, will be dissolved after alkaline metal ions by capillary phenomenon penetrate to the stone surface or caulking false, further formation of white China. Therefore, the prevention of water and alkaline metal ions penetrate into the surface of the stone or caulking inaccuracies, can prevent the occurrence of white China.

The traditional wet paste method in order to avoid this phenomenon, the light colored stone (yellow, white) mainly used white stone adhesive paste, so, even if the bleeding is white stone binder color, not easy to identify. But this method has two disadvantages: one is palliatives, no to solve the efflorescence phenomenon fundamentally occur; second, white stone is a white cement binder as the base material, under the same conditions of white cement strength is weaker than the cement, and the back of stone are relatively smooth, hollowing phenomenon will inevitably occur.

Two, the main characteristics of ceramic tile, stone waterproof adhesive:

The "double card" tiles, stone waterproof adhesive is a new technology of functional decorative accessories to solve the above problems emerged based on high quality polymer solution after preparation, with a special powder by two-component form after mixing the painted stone back, it can form a layer with high strength and anti-seepage performance of hair surface. Its anti permeability reached 24h50 mm water column test without leakage, namely in the stone back to form a waterproof layer, prevent leakage, thereby preventing efflorescence phenomenon. In addition, the bond strength is more than 1MPa, higher than the stone adhesive generally practiced in the 0.5MPa standard, and the formation of the hair surface, and can enhance the adhesive bond strength and to a greater extent to ensure safety of stone wet paste.

Thus, the "double card" tiles, stone waterproof adhesive processing stone, the binder request would not be so strict. So, in the wet paste material cost does not increase cost, and the white stone basic binder almost.

Three, the application of stone waterproof adhesive:

Understand the above two points, we can know that the "double card" tiles, the actual application of stone waterproof adhesive:

1, the site used in the decoration engineering, decoration companies by purchasing gum stone construction, which is controlled by the decoration decoration engineering enterprises, to achieve the desired results.

2, used in the stone within the enterprise. As we know, stone enterprises in cutting stone, in order to reduce the damages in the stone cutting into finished products and transportation process, usually by back with stone back, using the traditional gum resin type, low bond strength, also do not have anti permeability. Usually have to shovel out the back layer through networks. In the stone wet paste before the "double card" after the stone tile, waterproof adhesive, can completely replace the traditional back by sticking. Although the cost is higher than that of resin type, but does not need to be eradicated, saved the cost of resin adhesive, so on the total cost, but to the bottom.

At present, many large stone enterprises are updated in the traditional way, better adapt to the development of the industry. This need not be eradicated, with anti permeability, high strength adhesive has become a new selling point of ceramic tile, stone enterprise products
