Is nano sponge harmful to our health when doing housework?

Nano-sponges are also known as magic clean sponge friction, the technical term is melamine sponge () . Konjac sponge manufacturer Household stainless steel products, bathroom supplies, glass products, ceramic tiles, leather sofas, cars, tables and chairs, wood floors and other items of the cleaning effect is very good, only need water can quickly remove stains, so speed is familiar.

However, it is reported that the raw material in nano sponge is melamine, which means melamine. Is this harmful to the human body? The main cause of concern is the aftermath of the scandal of melamine contaminated milk powder. However, melamine is not toxic, and the milk poisoning incident is because children ate milk powder mixed with melamine. Melamine is not toxic, but it doesn't mean it can be eaten. Just like 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 indigestible and has no nutrients. Unscrupulous manufacturers add nitrogen to milk powder in response to institutional testing. Children are naturally indigestible, which leads to kidney calculi, long-term malnutrition and big-headed dolls.

In contrast to melamine, more and more Chinese people are concerned about the amount of formaldehyde released by magic rub. Here we Xiamen Sihang also for you to explain in detail.

1. It is 50 times the standard, and the screenshot says "Secondary textiles only (direct contact with skin) u003C 75mgu002Fkg". According to GB 18401-2010 "B direct contact with skin", the formaldehyde content should not exceed 75mgu002Fkg. Try on a piece of cloth as underwear. This kind of fitting is too casual and meaningless.

2. The maximum allowable concentration of formaldehyde in indoor air is 0.08 mg u002Fm3 according to the hygienic standard for formaldehyde in indoor air. The nano-sponge was put into an airtight beaker to measure the concentration of formaldehyde. In this way, you will expect the material in your home to exceed the limit. It should be noted that formaldehyde concentrations are measured in indoor air, rather than in a closed box where decorations are purchased.

3. Formaldehyde is a water-soluble and chemically unstable substance, which will dissipate before accumulation. Compared with the convenience in nano sponge, there are many disadvantages of previous cleaning appliances (nano sponge is not easy to be molded, and people who have used it should pay attention to the fact that stainless steel wire does great harm to tableware, sponge is badly molded, and ordinary rags are the center of fungi).

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 is currently GB9690-2009, which requires the migration of formaldehyde. Although tableware is different from nano sponge, it is all melamine, and it is all kitchen supplies. You can learn from it before the national standard of nano sponge has been issued. According to this standard to identify whether nano sponge meets the standard, rather than blindly saying that the formaldehyde emission is unqualified. There are many things containing formaldehyde. As for the consequences, it is better not to exceed the standard.

The results provide a systematic framework for scientists studying different bacterial communities to test which structural environments are best for their research, this must take full account of our use of bacterial management in the production development process.
