How to buy a chandeliers with high quality and low price
After the rough embryo is processed, three processes such as plating and painting are generally required. All three methods need to check their surface adhesion. Inspection of adhesion is now the most commonly used is the hundred-character grid test, that is, on the object to be measured, with a blade cut into 100 spacing 1 mm "well" shape, and then use adhesive tape to stick. If it can stick out, it means that the adhesion is not enough. Secondly, check whether the hardware surface has black, rust, scratches, less paint, paint off, paint leakage, flow paint, dirt and other undesirable phenomena; whether the entire lamp with a color difference; hardware parts with or without deformation. Since many parts of the hardware are welded, check whether there are excessive bumps or missed welds; whether the position of the weld pipe or nut is vertical in the bend pipe (if it is not 90 degrees, the assembled lamp may beæª). The customer often complained that the hand was scratched and bleeding during the lamp installation. This is due to the fact that the metal was not polished off during the machining process. In the entire lamp body, the electrical part is the most dangerous place, and it is easy to have a safety accident, so it must be strictly checked. Electrical inspections generally have two methods, visual inspection and tool inspection. Visual inspection: whether the wire is damaged, whether the lamp is deformed, broken, or missing corners, whether the lamp tongue is skewed, loose, and whether the positive and negative poles are close (in case of approaching, the light bulb can easily be connected), and whether the ground wire is loose or broken. If there is no sheathing at the outlet, there is no sheathing (there is no wire sheathing, the wire is easily scratched by the sharp metal, resulting in leakage). Whether the cap is tightened or not, and whether the size of the connector is appropriate (too small to be leaky or without electricity, too much waste) )Wait. Visual inspection can only be used for visual inspection. In fact, it also needs testing equipment, such as multimeter (check conductivity), high-voltage tester (usually high pressure is: 2U+1000, check leakage and short circuit), grounding resistance tester (resistance Whether the value is greater than the specified value, etc. The glass occupies a very important position in the chandelier. If the glass is beautiful and the quality is guaranteed, it will be able to play a good role in the light and complement each other. Glass is generally tested in terms of specifications, smoothness, weight, and appearance. Not long ago, Mr. Wang bought an eight-headed chandelier in a shopping mall. After returning home to assemble, he found that the lights lean towards one side, which is neither ugly nor safe. Upon inspection, there was originally a glass cover with uneven thickness, weighing 0.4 kg less than the other shades. In general, the glass weight tolerance is 0.05-0.1 kg, and the specification is 0.3-0.5 mm. The appearance means that the acid-etched glass cannot transmit light, the glass cannot contain impurities, and the surface cannot have dirt. Black spots, in addition, the glass should be smooth, and the phenomenon of rough fronts and roughness cannot occur. If you lock the glass with a male thread, it must be able to lock, otherwise the glass will fall and hurt people.
