In addition to Nano-sponge, there is also Magic Sponge (Melamine Sponge) and Magic Wipe. biodegradable dish sponge It is technically called Melamine sponge (Melamine Sponge). Stainless steel products, bathroom supplies, glass supplies, ceramic tiles, leather sofas, cars, tables and chairs, wood floors, and other items can be easily cleaned with water, so everyone is familiar with it after a few uses.

It has been reported that the raw material used in nano-sponges is melamine, which is not harmful to humans. melamine foam bulk The reason some may have concerns is due to the melamine-tainted milk powder incident. However, it should be noted that melamine itself is not toxic. The tainted milk powder caused harm because it was mixed with melamine and consumed by children. Just because something is non-toxic does not mean it is safe to consume. For example, a stone may not be poisonous, but if ground into a fine powder and ingested, it can cause problems such as indigestion, malnutrition, and even death. This is because melamine cannot be digested and does not contain any nutritional value. Unscrupulous businesses added it to milk powder in order to artificially increase nitrogen levels for passing agency tests, which resulted in children developing kidney stones and long-term malnutrition, leading to the condition known as "big-head dolls."

More and more people are concerned about the amount of formaldehyde released by magic wipes, bulk loofah 6 inch as opposed to melamine.

One says 50 times the standard, but the screenshot indicates that the formaldehyde content of the product must not exceed 75mg/kg in accordance with textile class II (direct contact with the skin) requirements, i.e., in compliance with the "National Textile products basic safety technical specifications" GB18401-2010 "Class B - direct contact with the skin". This test is too casual and does not show anything if dishcloths are tested as underwear.

As per the "Health Standards for Formaldehyde in Living Room Air", the approved limit for formaldehyde concentration is 0.08 mg/cubic meter. To measure this level, place the nano-sponge in a sealed large beaker. However, using this method may reveal that all materials used in home improvement exceed the standard. It is important to clarify that the concentration being measured pertains to formaldehyde in indoor air, not confined spaces such as small boxes.

Formaldehyde is a water-soluble and chemically unstable substance, which is dissipated until enriched. Compared with the convenience brought by nano sponges, and the disadvantages of many cleaning utensils before it (nano sponges are not easy to mold, people who have used them should have noticed that stainless steel wire is harmful to tableware, sponge mold is a serious problem, and ordinary dishcloths are fungus centers).

Since 1980, the state has introduced relevant standards regarding the use of melamine resin for tableware. These standards have been modified twice and are currently known as GB9690-2009. This standard requires a specific level of formaldehyde migration, which applies to both tableware and nano-sponge. Although they are different products, they both contain melamine and are considered kitchen supplies. Until a national standard for nano-sponges is established, reference can be made to this standard to determine if the product meets requirements. Rather than simply stating that the formaldehyde release is not qualified, it is important to consider that many items contain formaldehyde and it is crucial to adhere to the designated limits. Overstepping these limits may have potential consequences, therefore it is necessary for products to comply with the set standards.

After wetting, the nano-sponge forms a nano-capillary, which has a very strong cleaning effect, but the nano-sponge is meant for cleaning supplies that are not edible.

Furthermore, the nano-sponge itself is physically stable, does not melt in water, and can also withstand fire.

Nano-sponge products are of uneven quality on the market, the choice of time to pay closer attention to business selection, and regular business of high-quality nano-sponge using improved foam process, compression process, formaldehyde curing process, nano-sponge showing good density, no odor, good flexibility, wear and durability, and stronger cleaning power.

There are also a number of other terms for nano-sponge, including cleaning sponge, magic sponge, and magic wipe. However, the technical term is Melamine sponge. When cleaning household stainless steel, bathroom supplies, glass supplies, ceramic tiles, leather sofas, cars, tables and chairs, wood floors, and other things, only water is needed to quickly remove stains, so it is easily familiar to everyone.

Although the raw material used in the production of nano-sponge is melamine, there have been concerns about its safety due to the melamine-tainted milk powder incident. It is important to note that melamine itself is not toxic and does not pose a threat to human health. The issue arises when it is added to food products like milk powder, which can cause digestive problems and malnutrition in children who consume it. Just because something is non-toxic does not mean it is suitable for consumption, similar to how stones are not poisonous but can cause harm if consumed as a powder. Melamine cannot be digested and does not provide any nutritional value. Unscrupulous businesses often use it to increase nitrogen levels in their products to pass agency testing, resulting in serious health consequences such as kidney stones and malnutrition in children, known as "big-head dolls."

As a contrast to melamine, more and more people are concerned about the amount of formaldehyde released by magic wipes.

said 50 times the standard, there is such a line in the screenshot "limit according to textile class II (direct contact with the skin) requirements < 75mg/kg", i.e., formaldehyde content shall not exceed 75mg/kg in accordance with the "National Textile products basic safety technical specifications" GB18401-2010 "Class B - direct contact with the skin". This test is too casual to be used as underwear for dish cloths.

According to the "Health Standards for Formaldehyde in the Air of Living Rooms", a concentration of 0.08 mg/cubic meter is considered the maximum allowable level. To accurately measure this concentration, place the nano-sponge in a large closed beaker. Following this measurement method, it is likely that all materials used in home improvement will exceed the standard. However, it is important to differentiate between the concentration of formaldehyde in indoor air and that within a closed small box.

Formaldehyde is a water-soluble and chemically unstable substance, and it has dissipated until it is enriched. In contrast to the convenience brought by nano sponges, and the disadvantages of many cleaning utensils before it (nano sponges are not easy to mold, people who have used them should have noticed that stainless steel wire is harmful to tableware, and sponge mold is extremely dangerous, and ordinary dishcloths become fungus centers).

The state has set standards for the use of melamine resin in tableware since 1980. These standards, currently known as GB9690-2009, have been amended twice. While tableware and nano-sponges are different products, they both contain melamine and are used in the kitchen. Therefore, until a national standard for nano-sponges is established, we can refer to this existing standard to determine if a nano-sponge meets the required amount of formaldehyde migration. Instead of simply stating that formaldehyde release is not up to par, it is important to consider that many items may contain this substance and whether or not their levels exceed the standard.

As a result of its special three-dimensional network structure, the nano-sponge forms a nano-capillary after wetting, which has a very strong cleaning effect, but it is used for cleaning supplies, which are external, but not edible.

Moreover, the nano-sponge itself has good physical stability, does not melt in water, and is fireproof.

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 producing 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, stronger cleaning power.
