There are many people like to use stainless steel household utensils food, but not all stainless steel household utensils are qualified. Some say, with the magnet can identify the stainless steel can't dress up food, is that true? Pledges inspect bureau staff after authorities said, with the magnet identification method. To determine whether the stainless steel products for food grade, use stainless steel to identify fluid. Province pledges inspect bureau products quality inspection center, said the consumption level of the product must not be corrosion of stainless steel. Society can use magnet adsorption, through 'has magnetic' or 'non-magnetic' to identify the true and false of stainless steel is unreliable. Because, stainless steel with and without magnetic, basically see the injection of chromium and nickel content in liquid steel, a lot of high-level stainless steel products may be of weak magnetism, and some of the counterfeit inferior can do it 'non-magnetic stainless steel products. So for stainless steel, whether or not the magnet suck up, as long as meet quality standards, are stainless steel. Iron boron permanent magnet and called modern industrial monosodium glutamate, as a kind of modern industrial important high performance magnetic materials to promote contemporary technology field and the progress of the society, is widely applied in various fields, how to determine the most comprehensive product advantages: permanent magnet, magnetic; Second, the size of the magnet; Three, surface coating. Firstly, magnetic, decision is the key to control the production process of the magnetic properties of raw materials. 1, raw materials manufacturers, according to business requirements or middle-grade or low-grade sintered ndfeb, raw material purchase of raw materials in the proceedings of the national standard, the company sales of high-grade ndfeb only. 2, advanced production process also determines the quality of the performance of the magnet. 3, the quality control is very important in the process of production. Second, the magnet shape size and tolerance values by using various shapes of ndfeb magnets, such as round, shaped, square, tile shape, trapezoid. Different size of the material is to use different machine tool cutting crude materials for processing, advanced technology and machine operator determines the accuracy of the product. Three coating, surface coating processing surface quality coating, zinc, nickel, nickel and copper nickel plating such as copper and gold plating process. Can the plating options for products according to customer's request. Summary of product quality, a brief summary, is a fine performance, dimensional tolerance control, determine the appearance of the coating testing and evaluation. Detection of magnet flux gaussian surface, such as testing; Size tolerance, can use vernier caliper measurement accuracy; Coating, coating color and brightness and coating binding force, and through the magnets, the surface is bright and clean appearance observation, without spots, with or without edge off Angle, to assess the quality of the products.
