Is the use of nano-sponges harmful to our health when doing housework
Nano sponge is also called cleaning sponge magic sponge magic wipe, stainless steel spongeand the technical term is melamine sponge (melamine sponge). Cleaning household stainless steel products, bathroom products, glass products, tiles, leather sofas, cars, tables and chairs, wooden floors and other things are very effective, and only need to use water to quickly remove stains when cleaning, so it is quickly familiar to everyone.
However, it is reported that the raw material of the nano-sponge is melamine, which is harmless to the human body. The main cause of doubt is the impact of the melamine-tainted milk powder incident. However, melamine (melamine) is non-toxic and the tainted milk incident was caused by melamine-tainted milk powder being consumed by children. Non-toxic does not mean edible. Just like stone is non-toxic, if you beat it into powder and eat it, there will be problems, indigestion, malnutrition, and even death. Melamine itself is not digestible, is not nutritious things. Bad companies put it in milk powder to increase nitrogen content as a response to institutional testing, children eat natural digestion caused by kidney stones, chronic malnutrition, leading to big head baby.
In contrast to melamine, more and more people are concerned about the formaldehyde emission of magic wipes. Here, Xiamen Sihang will also explain it in detail.
1. represents 50 times the standard, with a line in the screenshot that reads, “The limit required according to textile class II (direct contact with skin) & LT; 75 mg/kg”, the content of formaldehyde shall not exceed 75 mg/kg according to GB18401-2010“Class b-direct contact with skin”. If you test napkins as underwear, the test is so random that nothing shows up.
2. According to Hygienic Standard for Formaldehyde in Indoor Air, the maximum allowable concentration of formaldehyde in indoor air is 0.08mg u002F m3. Nano sponge was placed in a closed beaker to measure the concentration of formaldehyde. According to this measurement method, all materials in home decoration may exceed the standard. It should be noted that the concentration of formaldehyde is the concentration of formaldehyde in indoor air, not the concentration of formaldehyde in a closed small box.
3. Formaldehyde is a water-soluble and chemically unstable substance that has dissipated until it is enriched. Compared with the convenience of nano-sponge, as well as the shortcomings of many previous cleaning appliances (the nano-sponge is not easy to form, users should have been aware of the stainless steel wire on tableware hazards, sponge formation is very serious, the common dishcloth is the center of fungus) .
4. If melamine resin is used for tableware, in fact, as early as 1980, the state has already issued relevant standards. The standard has been revised twice, and it is currently GB9690-2009, in which there are requirements for the migration of formaldehyde. Although tableware and nano sponge are different, they are also melamine, and they are all kitchen supplies. Before the national standard of nano sponge has been issued, we can also learn from it to identify whether nano sponge meets the standard according to this standard. Instead of blindly saying that the amount of formaldehyde released is unqualified. There are many things containing formaldehyde. As for the consequences, it is better not to exceed the standard.
Due to its special three-dimensional network structure, the nano-sponge formed after wetting nano-capillary, has a strong cleaning effect, but the nano-sponge is used for cleaning supplies, is external, can not be eaten.
Moreover, nano sponge itself has good physical stability, is insoluble in water, and can also prevent fire.
However, the quality of nano-sponge products on the market varies, so we should pay more attention to the choice of enterprises when choosing, regular high-quality nano-sponge enterprises using improved foaming process, compression process, curing formaldehyde process, nano-sponge shows high density, odor-free, good flexibility, wear-resistant and durable, cleaning ability is strong.
Although stubborn smudges and marks can be removed with dish soap or mineral oil, stainless steel cleansers are the most effective approach to restore your appliance's original sheen. Additionally, search for a cleaner that has a protectant to help ward against dirt and fingerprints.
