Is nano coconut sponge harmful to our health when doing housework?
Nano-coconut sponge is also known as the magic clean coconut sponge friction, the technical term is melamine coconut sponge () . kitchen sponge brandHousehold 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 of nano coconut sponge is melamine, sponge wholesale manufacturerwhich 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-coconut sponge was put into an airtight beaker to determine the content 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 of nano-coconut shreds, there are many disadvantages of previous cleaning appliances (nano-coconut shreds are not easy to form, and people who have used them should pay attention to the fact that stainless steel filaments do great harm to tableware, and the formation of coconut shreds is very serious, and ordinary rags are the center of fungi).
4. If melamine resin used as tableware, in fact as early as 1980, the relevant national standards have been issued. This standard has been revised twice and is now GB9690 -2009, which requires the migration of formaldehyde. Although cutlery and nano-coconut sponge are different, but are melamine, are kitchen supplies, before the introduction of national standards of nano-coconut sponge, you can learn from everyone. To identify the nano-coconut sponge according to this standard, rather than blindly say that the release of formaldehyde is substandard. There are many things that contain formaldehyde, as a consequence, or not exceed the standard.
Because of its special three-dimensional network structure, nano-coconut city forms nano-capillaries after wetting, which has a very strong cleaning effect. However, nano-coconut city is used for cleaning products and external use, but we can't avoid eating it.
In addition, the nano-coconut sponge itself has good physical stability, insoluble in water, fire-resistant.
The quality of nano-coconut cotton products on the market is uneven, and more attention is paid to the choice of merchants. High-quality nano-coconut sponge made by regular merchants adopts improved foaming process, compression process and mature in addition to formaldehyde process, and nano-coconut presents the characteristics of high density, no peculiar smell, good flexibility, wear resistance and durability, and stronger cleaning power.
