Generally, the price of radiation protection suits is more than 500 yuan in 600 yuan, but the time required to use them is only 10 month at most, so many expectant mothers tend to wear radiation protection suits given by relatives and friends instead of buying one. But in this way, the question comes: does the radiation protection suit have a shelf life? Will the radiation protection effect be affected if the validity period of the radiation protection suit expires? Radiation protection suits are not food, so there is no shelf life. However, its radiation protection function will be weakened, which is related to the material and maintenance of radiation protection clothing. Many mothers will give radiation protection suits to relatives and friends to continue to use after giving birth, so as not to waste resources. In fact, the effect of second-hand radiation protection clothing has been reduced. Because after ten months of use, the metal fibers inside have worn out. At present, there are mainly two kinds of radiation protection suits on the market. One is made by blending stainless steel silk fiber and cloth fiber. This radiation protection suit can be cleaned, but because it is a blended fabric, it cannot be separated and should not be washed more. In the process of cleaning, the radiation protection clothing of blended fabrics must be gently hand-washed with neutral soap, never use a washing machine, and don't twist it hard after hand-washing, just hang it up and dry it. When cleaning radiation protection clothing, the water temperature must meet certain standards, preferably not too high, and bleaching or using washing powder containing bleaching ingredients is not allowed. This can reduce the abrasion of stainless steel wire fibers during cleaning. Another is to use the coating process to coat a layer of radiation-proof metal film on the basis of the original cloth. This radiation protection suit can't be cleaned, so as not to make the metal particles on the surface peel off during the cleaning process, which will affect the radiation protection effect. It is precisely for this reason that many radiation protection suits using this coating process are now double-layer detachable and can be washed separately. If the radiation-proof maternity dress is not disassembled in pairs, it must not be washed. If it is directly rubbed, it will cause great damage and affect the radiation protection effect and service life. Generally speaking, anti-radiation silver ions have a certain shelf life, because they are easily oxidized, and the effect is generally good at first, but almost at the later stage. So now the industry's saying about silver ion is that it is silver, and the reason why metal ions can wear for a long time is because it acts on the metal fibers inside, as long as the metal wires inside are not broken. It is suggested that when purchasing, ask the manufacturer what kind of raw materials are used for the radiation protection fabric, and use clean radiation protection clothing according to the product instructions. However, there is still a problem. If you don't wash a dress for several months, there will definitely be a lot of bacteria on it. However, radiation protection suits are generally not washable. What should I do at this time? It is best for pregnant women to put their clothes in the sun for a period of time before reaching them and sterilize them with ultraviolet rays. Of course, if the pregnant mother decides to buy a new radiation protection suit, there is no need to worry about the expiration date of the radiation protection suit.
