Since the beginning of winter, the weather has become drier and colder. Drinking a few sips of warm water can instantly warm your body and make you feel comfortable. Every time this season comes, thermos cups are a hot-selling season. With a thermos cup for each person, the whole family can drink hot water anytime and anywhere to stay healthy.
The common material of thermos cups is stainless steel, so what should you pay attention to when purchasing stainless steel thermos cups? Xino, the drafting unit of the cup and pot industry standards, introduced some knowledge about the material and liner of stainless steel thermos cups.
The inner bladder of the thermos cup is in direct contact with the liquid contained and is the core component of the thermos cup. A high-quality thermos cup should have a smooth inner liner and no traces, and a smooth and smooth edge. The country also has strict requirements for the stainless steel liner of the thermos cup, and the material must meet food-grade standards.
What do consumers often hear about 304 stainless steel or 316 stainless steel?
304 and 316 are both stainless steel grades, representing two stainless steel materials. Strictly speaking, they are stainless steel grades produced in accordance with American ASTM standards. Stainless steel grades vary from country to country. If it is SUS304 or SUS316, it is a Japanese grade. my country’s stainless steel grades are a combination of chemical composition and numbers. For example, in the food contact material list of Sino thermos cups, the stainless steel parts are made of austenitic stainless steel (06Cr19Ni10) and austenitic stainless steel (022Cr17Ni12Mo2). That is, corresponding to 304 stainless steel and 306L stainless steel respectively.
Where should consumers find product material information?
Qualified thermos cup products will have relevant material descriptions on the outer packaging and instructions. According to the “National Standard for Stainless Steel Vacuum Cups” (GB/T 29606-2013), the product or minimum sales package should have the material type and grade of the inner tank, outer shell and stainless steel accessories in direct contact with liquid (food), and the instructions should be Included are stainless steel types for these attachment materials.
In addition to the above provisions, the national standard does not have unified requirements for the stainless steel material type and grade to be marked in other locations on thermos cup products. For example, whether there is a brand steel stamp on the inner liner of the cup only depends on what the mold looks like. If the inner pot is stamped with steel, it will be uneven, which will easily trap dirt and make it more difficult to clean the cup.
Of course, when choosing a thermos cup, in addition to the liner, the appearance, craftsmanship and details cannot be ignored. Sino advises consumers to pay attention to whether the surface of the thermos cup is smooth and scratch-free, whether the welding joint is smooth and consistent, whether the cup lid opens and closes smoothly, whether the sealing performance is good, the material of the accessories, the weight of the cup body, etc., should be paid attention to when purchasing. , you might as well consider them together.
