Nano-sponge magic wipe is completely non-toxic and can be used to wash dishes and cups. Sponge dishwashing generally saves cleaning agent, and the ability to absorb hidden things is very strong, is a very good dishwashing appliance. Sponges are porous materials that absorb water well and can be used to clean things. In the selection of sponge, mainly to its touch and elasticity as the primary factor. It should be soft to the touch and malleable. Many people think that the magic magic rub (also known as nano sponge) toxic is it formaldehyde, but after a series of experiments said that nano sponge and formaldehyde did not exceed the standard, itself has good physical stability, is insoluble in water, the parameters are in line with environmental standards, all can be assured to use. But just because it’s not poisonous doesn’t mean it’s edible. Keep it out of reach of children to avoid ingestion. Magic wipe formaldehyde is not toxic three reasons: 1. One of the characteristics of formaldehyde is very soluble in water, usually with nano sponge magic scrub bowl is soaked in water and then used, and the pore structure up to more than 95%, easy to absorb water. So even if there is some formaldehyde inside the nano sponge magic wipe, dissolved in water after the residue is very little. And formaldehyde is not used in a confined space, so much less enrichment, it has dissipated. 2. The use of magic wipe must be water, so that of the formaldehyde has been removed, as long as the entrance of the bowl dish with water rinse several times, more ventilation to dry, you do not have to worry about formaldehyde will remain in tableware, eating utensils. 3. Some people are worried about the use of nano sponge magic wipe is very close to us, it will not let the formaldehyde concentration of the surrounding air increase and affect our health? To answer this question, let’s do an experiment: the process of the experiment is very simple, that is, in a room with al one desk, test the formaldehyde concentration in the air of the room itself, and then put the nano-sponge magic wipe about 250px away from the test box to test whether the formaldehyde concentration in the air increases. Nano sponge formaldehyde test shows that the formaldehyde content is still in 0.03~0.05/m3, just opened nano sponge is when the concentration of formaldehyde content is high, but we are in use when nano sponge is used after soaking in water, formaldehyde dissolved in water is not so high content. 4. Nano sponge magic rub although contains formaldehyde, but formaldehyde is in the standard range of values, do not blindly say that there is formaldehyde release is not qualified. There are a lot of things containing formaldehyde, as for how much will be the consequences, or not exceed the standard.

Some sponges are poisonous. Those that are soft and colourful are likely to be poisonous chemicals. The commonly used sponge is made of foamed plastic polymer, and the recycled sponge is a new type of product, which is mainly formed by crushing, stirring, and high-temperature sterilization of glue steam. Its advantages are good elasticity, good resistance, no odor, and the production cost is lower than that of ordinary sponges. Why do sponges catch fire so badly? Ordinary sponges are actually not very easy to catch fire, and the combustion of sponges requires the presence of heat and oxygen to occur. The sponge will not burn unless it encounters an open flame. For example, an unextinguished cigarette butt falls on the sponge. Under the action of high temperature, the sponge is easily melted, wrapping the cigarette butt, so that the cigarette butt is isolated from the air and extinguished. But the sponge is still very easy to catch fire under the action of an open flame. There are a lot of pores in the sponge. The lower the density of the sponge, the higher the porosity, the lower the ignition point, and the easier it is to catch fire. The pores in the sponge are equivalent to expanding the contact area between the fuel and the air. Therefore, the sponge burns faster and at a higher temperature than ordinary materials. What’s more serious is that after the sponge catches fire, the smoke emitted by the sponge also contains toxic gases. Common sponges in the market include polyurethane type, polyethylene type and polystyrene type. When these types of sponges are burned, they will release toxic gases containing cyanide, carbon or benzene, and the human body will suffocate quickly after excessive inhalation. From the material point of view, the recycled sponge is synthesized from sponge scraps. The properties of the base material are similar to those of ordinary sponges, and the ignition characteristics should be similar.

Latex generally refers to a colloidal emulsion formed by dispersing polymer particles in water. It is customary to refer to the aqueous dispersion of rubber particles as latex; the aqueous dispersion of resin particles is called emulsion. Latex products processed from latex as raw materials, also known as latex products, such as sponges, gloves, toys, hoses, etc., are widely used in daily life. Classification natural latex It flows out from rubber tree tapping (see natural rubber), which is milky white, with a solid content of 30% to 40%, and the average rubber particle size is 1.06μm. Fresh natural latex contains rubber components 27%-41.3% (mass), water 44%-70%, protein 0.2%-4.5%, natural resin 2%-5%, sugar 0.36%-4.2%, ash 0.4% . In order to prevent natural latex from coagulating due to the action of microorganisms and enzymes, ammonia and other stabilizers are often added. In order to facilitate transportation and processing, natural latex is concentrated to a solid content of more than 60% by centrifugation or evaporation, which is called concentrated latex. Natural latex is mainly used in sponge products, extruded products and impregnated products. synthetic latex Generally, synthetic latex (such as polybutadiene latex, styrene-butadiene latex, etc.) with a solid content of 20% to 30% can be obtained by emulsion polymerization. In order to make the solid content reach 40% to 70%, the rubber particles are ly agglomerated into larger particles, that is, in the industry, measures such as adjusting the polymerization formula, adding agglomerating agents, stirring, pressurizing, freezing, etc. Natural rubber latex is concentrated in a similar way. Synthetic latex is mainly used in industrial sectors such as carpet, paper, textile, printing, coatings and adhesives.

Memory foam refers to a polyether polyurethane foam sponge with slow rebound mechanical properties, which is a special sponge developed by a European company. When the flat memory foam surface is pressed by hand, a fingerprint will appear and then slowly disappear. This is the iconic effect of memory foam – “slow rebound”, and it is difficult for other materials to imitate the slow speed of its rebound. The memory foam is soft to the touch. When you hold the memory foam with your hand, you will feel that the palm of your hand is constantly empty, such as an hourglass. When people sit on the memory foam waist pad, they will feel the gradual settling process, like falling into a quagmire, and hear the subtle sound of the continuous flow of gas in the memory foam; when people sit on the memory foam waist pad, they will be deformed continuously at , and then the sense of resistance will disappear. , and the back pain that should have appeared after sitting for a long time, it is hard to find traces. Comprehensive performance (1) It has performance in mechanics such as absorbing impact force, reducing vibration, and releasing low rebound force; it is a buffer material to protect the body of astronauts when the space capsule lands, and it is the material for the packaging of valuable instruments. (2) Provide uniform surface pressure distribution; adapt to the surface shape of external pressure through stress relaxation, so as to reduce the pressure at the point to a , thereby avoiding the parts with microcirculation pressure, and it is a long-term bed rest to effectively prevent bedsores. It can gently maintain the shape of foreign objects and is a good material for posture cushions. (3) Molecular stability, no toxic and side effects in contact with human body, no allergies, no volatile irritating substances, good flame retardant effect and other reliable chemical properties

Filter sponge is a high-tech material. It is designed for astronauts to help relieve the stress astronauts experience during takeoff, landing and flight. Due to the pressure relief characteristics of filter sponges, filter sponges are widely used in many places. Let’s take a look at the unknown side of the filter sponge? Filter sponge is also called mesh sponge, blasting sponge. Polyurethane filter sponge is made of ordinary open-cell soft foam through reticulation treatment. The reticulation treatment removes the original mask or wall film between the foam networks and obtains the main skeleton network structure. The porosity of the filter sponge is as high as 97%, with air permeability, good softness and high mechanical strength. The difference between filter sponges and traditional sponges and liposuction: filter sponges can absorb the weight of the body and feel like floating in the air. The filter sponge follows the body type rather than the body type like sponge and polyester cotton, which can make people more adaptable to it. Full body, neck, and lumbar support can be provided by allowing the spine and joints to rest in their natural physiological state. Completely release stress and enjoy a weightless feeling. The material of the filter sponge is antibacterial according to European standards. Its high-density material can effectively resist the penetration of sweat and odor, which can ensure personal hygiene and is harmless to human health.

BS-Polyurethane sponge filler Polyurethane bio-sponge filler is made by double blasting of oxygen and hydrogen, and the pores are uniform and interconnected, so as to achieve an all-round bacterial culture carrier of the whole bio-sponge filler. Polyurethane sponge biological filler, its porous and transparent structure greatly increases the specific surface area of the product, which is conducive to the mass reproduction of cultured bacteria, large hanging modulus, and short time. It is an efficient filler product. As a sewage treatment filler, it has been recognized and recommended by the majority of scientific research units. Polyurethane bio-sponge filler is suitable for high-concentration organic wastewater, various industrial wastewater, oil refining wastewater, daily chemical wastewater, pharmaceutical wastewater and urban domestic sewage for denitrification and phosphorus removal and other sewage treatment projects. BS-Hydrophilic gel filler Moving Bed Biomagic MBBR Craft By adding a certain amount of suspended filler to the gas explosion tank, a large number of microorganisms are attached to the suspended filler to form a biofilm. When the sewage flows through, the organic matter in the sewage acts as a nutrient and is taken up by the microorganisms on the biofilm. At the same time that it grows and reproduces itself, the sewage is purified, which increases the biomass and biological species in the aeration tank, thereby improving the sewage treatment efficiency of the aeration tank. Suspended filler is the core part of the MBBR process, and its performance directly affects the attachment of microorganisms, thereby affecting the effect of biofilm treatment of sewage. When choosing a suspension filler, the following three points are particularly important: Hydrophilic performance: determines whether microorganisms can more easily attach to the filler, whether they can quickly deal with sewage treatment, Specific surface area: The larger the specific surface area, the more the amount of microorganisms attached, the higher the sewage treatment efficiency. Porous ventilation: The inside of the packing can also maintain sufficient oxygen supply, and it is not easy to block.
