At present, it is recognized that the safest material in contact with food is stainless steel. Stainless steel tableware is cold-resistant and heat-resistant, corrosion-resistant and high-temperature-resistant, not easy to break, easy to clean and disinfect, mostly vacuum sandwich, light and easy to use.
Common stainless steels are divided into 304 and 3 16 stainless steels. 304 stainless steel is commonly used in children's thermos cups and bowls. The architectural design generally adopts 3 16 stainless steel.
304 stainless steel: it can resist the oxidation of chemical substances and is a material that must be used in the national pressure cooker standard. The standard material of stainless steel pressure cooker is above 304. Stainless steel is classified as a food-grade metal by national standards, and there is no problem in normal contact with water, tea, milk, coffee, beverage, juice, oil, salt, sauce and vinegar.
3 16 stainless steel: made of 10% nickel, which is more durable and corrosion resistant. This kind of stainless steel is called 18- 10 stainless steel, which is also medical stainless steel. There is no metal ion precipitation at all, which is very safe.
But for food-grade stainless steel used to make children's dinner plates, 304 is enough, and there are almost no defects. For home use, if you use 3 16, it is completely overqualified. They have little difference in appearance, but there are differences in composition, brand and composition. Generally, the utilization rate of 3 16 stainless steel is higher in architectural design, because 3 16 stainless steel is relatively more stable and safe in terms of high temperature resistance.
Most of the tableware in our daily life is porcelain, and most children will break the tableware because they are not familiar with eating habits. It doesn't matter if the plate is broken and wasted. The key is that parents and elders are afraid that their children will lose more than they gain. There are many kinds of products in the market with uneven quality. We must be careful when choosing food and tableware for our children. We should choose some materials that are relatively safe, pollution-free, and have no harmful substances falling off after long-term washing and wearing. Children's products must pay attention to safety first
