Is the use of nano-sponges harmful to our health when doing housework

Nanosponge graduate student

Nano sponge is also called cleaning sponge magic sponge magic wipe, magic erasers wholesaleand 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 has been reported that the raw material of nano-sponge is melamine, the konjac sponge companywhich is not harmful to the human body. The main reason why people have questions is the impact of the melamine-tainted milk powder incident. But melamine (melamine) is not toxic, and the tainted milk incident is because the milk powder mixed with melamine is eaten by children. Just because it‘s non-toxic doesn‘t mean it‘s edible. Just like a stone is not poisonous, if you break 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 businesses put it in milk powder to increase the nitrogen content in response to agency testing, children eat natural digestion caused kidney stones, long-term malnutrition, which leads to big-head dolls.

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, individually wrapped sponges bulk“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 the health standard for formaldehyde in indoor air, the maximum allowable concentration of formaldehyde in indoor air is 0.08 mg/m3. The nano-sponge into a large closed beaker to measure the concentration of formaldehyde, according to the measurement method, home decoration in all materials are likely to 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 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 is uneven, the choice of time to pay more attention to the selection of businesses, the regular business of high-quality nano-sponge using improved foam process, compression process, curing formaldehyde process, nano-sponge showed high density, no odor, good flexibility, wear and durable, cleaning power is stronger.
