subject: Buy Tiles Must Understand The Three Major Technical Standards [print this page] Another year decorate season, home renovations cannot leave the ceramic tile, kitchen, bathroom, living room, ceramic tile can be seen in everywhere, choose good ceramic tile, is creating a better home life of the first step; When we buy ceramic tile, we have to understand the technical standards of some tiles.
Will learn the technology standard one: enterprise's technical certification
Up to now, ceramic enterprise and technology related the authentication mainly ISO quality system certification, environmental label product authentication, 3 c authentication, the high quality product certification, the state building materials radionuclide limit standard, CE certification, etc., and some provincial product technical evaluation the authentication, the third party agencies product selection and so on.
Generally speaking, the strength of the powerful ceramic enterprises, most of them have a number of certification, to specially ceramics as an example, obtain the technology and product certification, including the ISO9001 and ISO14001 international quality environmental management double the authentication, through the porcelain brick product country 3C authentication, ten Central China environmental Labeling certification, etc., at the same time to participate in formulating a 3 ceramic products national standards, through the scientific and technological achievements appraisal eight, access to provincial and municipal levels of science and technology reward 11, the product continuous seven years in China's ceramic industry's cutting-edge standings obtain "cutting-edge products" award.
Will learn the technical standard two: the appearance look
To ceramic tile appearance inspection, mainly including such several: brick surface roughness, color uniformity, surface finish , color difference, lack of Angle, area, thickness and so on, tiles of good quality usually on these indicators can reach a higher level.
Among them, such as color uniformity aspects, arbitrarily singled out four tiles, tiled in a better light on the ground, look at the tiles color and luster are uniform or not; In the process of handling, ceramic tile is easy to damage. At the time of choose and buy must pay attention to check tile edge whether without gap. Tile surface flat inspection aspects, method is to two pieces of ceramic tile positive together, merged closely is the flatness qualified ceramic tile.
Will learn technical standards three: physical performance judgment
High quality tiles must be in physical performance excellent, also there are a lot of indicators, including water absorption, strength, thermal shock resistance, resistance to glaze cracking resistance, abrasion resistance, small color difference, frost resistance, impact resistance, linear thermal expansion coefficient, wet expansion, floor tile friction coefficient, etc.
Various certificates: these indicators can view the product detects report technical data, in order to be able to grasp that take a fancy to ceramic tiles substance performance, in particular, it is worth noting that, since August 2005, China began to China began to water absorption 0.5% the porcelain brick for mandatory radioactive detection, namely 3 c compulsory certification, when the choose and buy ceramic tile, it is necessary to understand.
