Tile hidden dangers, more practical purchase of senior guides to pass the secret
Recently, the General Administration of Quality Supervision, Inspection and Quarantine and the Forestry Bureau issued the results of the quality inspection of five types of forest products. Many of the brands associated with it have been recruited, and they have also pushed the floor problem to the forefront. In the building materials market, tiles and floors are secretly contested, so can it make people feel comfortable buying? 365 home exclusive attention. Tile quality inspection core exposure point full secret The home industry spans many categories and product lines. Because of the close relationship with the lives of ordinary people, it has always received much attention. At present, the authorities conduct quality inspections and release the results in a timely manner. The quality inspection scope is different for different product characteristics. As far as tiles are concerned, “the size, flatness, water absorption, breaking strength, modulus of rupture, glaze cracking resistance of glazed tiles, radioactivity, etc. have become the main quality inspection items. If the test fails, it will bring a series of The problem." Jin Lihua, the station manager of the complaints station of Nanjing Decoration Materials Trade Association, said, "When consumers buy, they can use iron nails and oily pens to simply test the performance of ceramic tiles. The quality of tiles that are not scratch-resistant and easy to absorb color will be But off." Subsequently, after careful comparison, these parameters have indeed become the main exposure point. Can't reach the standard hidden hidden dangers The core exposure points of these tile quality inspections, what harmful radiation will occur if they fail to meet the standard? For these most sensitive problems, Xiaobian telephone connected Xu Yalin, the chief inspector of Founder's inspection room, and Xugong explained the mystery. Xu Gong explained that if the tile size does not meet the specifications, then there will be gaps in the size of the tile when it is laid, which is very ugly. Glaze-resistant glaze cracking is used for the inspection of glazed tiles. In addition to the density of brick body, the material and thickness of the glaze are very important for the quality of the brick. If you can't get through, the bricks are prone to breakage. The harm caused by radioactivity is self-evident. The core exposure points of tile quality inspection are closely related to the quality of its products, so it cannot be ignored. The actual purchase of senior guides to teach secrets If a series of tile problems appear one by one, it will definitely make you feel a headache. How to avoid these hidden dangers as much as possible? Zhu Licui, a senior guide of Marco Polo Ceramics Jinling International Home Furnishing Store, taught some tips on brick selection. The flatness is the most basic index of the tile, and its inspection is very convenient. According to the introduction, the tiles are placed on the plane, and the four corners can be completely fitted, indicating that the flatness passes. You can check the water absorption rate of the tile by immersion. After soaking for 10 hours, there is a crack or watermark on the brick surface. It is recommended not to buy it. The radioactivity of the tiles is invisible, but the national authorities will issue relevant quality inspection reports, so you can refer to the purchase. In addition, Marco Polo ceramics Jinling International Home Furnishings senior guide Zhu Licui recommended the majority of decoration users, living room floor tiles purchase specifications with 25 squares as the demarcation point, more than 800cm * 800cm, less than 600cm * 600cm. At the same time, because the wall on the floor tile is involved in the secondary processing, it must take into account the wear and tear of the cutting, so as to avoid unnecessary replenishment troubles.
Globe valve is a forced-sealed valve, so the valve is closed, the pressure must be applied to the valve flap to force the sealing surface does not leak. When the medium from below the valve into the valve, the operating force needed to overcome the resistance is the valve stem and packing friction and the thrust generated by the media pressure, off the valve force than the valve open, so the valve stem The diameter should be larger, otherwise it will happen valve stem bend. According to the connection is divided into three kinds: flange connection, threaded connection, welding connection.When the globe valve is opened, the flap opening height is 25% ~ 30% of the nominal diameter, the flow rate has reached the maximum, indicating that the valve has reached the fully open position. Therefore, the full-stop position of the valve, valve stroke should be determined.
