Buy ceramic tiles to pay attention to radioactive indicators how to buy healthy and safe tiles

In addition, the owner asked the decoration team to work in the construction of the materials. For the quality of the craft ceramics and architectural ceramics used in the interior, the owner could not understand, and opened the door for the B and C tiles to enter the room. "In case these radioactive materials of tiles are unqualified, people living in them may be accompanied by radioactive materials for a long time." Zhengzhou star decoration designer Guo Ling told reporters that due to fierce market competition, at present, Zhengzhou home improvement market, some Irregular decoration companies and small guerrillas have adopted low-price strategies and made up their minds on decoration materials. They use Class B and C tiles to pretend to be Class A tiles for interior decoration, which can save costs by 20% to 40%. “So, our designers often remind owners that renovation cannot be used as a primary measure.”

Source of tile radiation

Many owners believe that ceramic tiles do not require adhesives such as glue, like wooden flooring, and there should be no indoor pollution.

Wu Yuanjiang, who has been engaged in ceramics business in Zhengzhou for more than a decade, told reporters that in the production process of ceramic tiles, in order to increase the surface finish, to facilitate cleaning and decontamination, and to avoid erosion, manufacturers have applied a layer of "glaze" on the surface (so tiles Also known as glazed tiles, this is a ceramic pigment in which zircon sand is added as an opacifier, while the content of natural radionuclides in zircon sand is generally high.

The radiation path of ceramic tiles to the human body is from the radiation of raw materials, the second is the irradiation of the elements from the (æ°¡) elements, and the glaze dust that has fallen off the service life or the man-made damaged tiles, which is inhaled by the human body, will endanger the health. . Among all the tiles, the ultra-white bricks in the polished tiles have stronger radiation, and the precipitation rate of the radioactive elements (æ°¡) on the surface of the glazed tiles is higher than that of ordinary bricks.

Boss Wu reminded that when buying ceramic tiles, pay attention to the following points: buy brand products from the formal building materials market; ask the dealers for radioactive test reports, and observe the types of test results (A best, B center, C worst); In order to prevent the indoor radioactive material content from being too high, it is best to have a professional agency conduct radioactivity testing before check-in.

Lubricants are divided into two areas, internal and external lubricants. The transition between external and internal lubricating effect is fluid, however, – internal lubricants often also have a certain external lubrication effect and vice versa. Lubricants having both effects are therefore called [combined lubricants".
Internal lubricants reduce the frictional forces occurring between the PVC molecule chains, thus reducing melt viscosity. They are polar and thus are highly compatible with PVC. They help achieve excellent transparency even at high dosages and do not tend to exudate, which helps optimizing welding, gluing, and printing properties of the final product.
External lubricants reduce the adhesion between PVC and metal surfaces. They are mostly non-polar such as paraffin and polyethylene waxes. The external lubrication effect is largely determined by the length of the hydrocarbon chain, its branching and its functional group. At high dosages they can lead to cloudiness and exudation
