The high-resilience sponge is produced and processed by using polyurethane (PU) high, medium and low density high-resilience foam composite materials. Its main component is polyurethane, English: PU. The high-resilience sponge has a mixed distribution of cell diameters, different skeleton thicknesses, and a large open porosity. When under pressure, it will produce different supporting forces and rebound forces under different deformation states, so it is called high-resilience sponge. High-resilience sponge process High-resilience cold-cured polyurethane foam formed by cold molding process has mechanical properties (high resilience, low hysteresis loss); high compression load ratio, so it has a significant sitting comfort. type; feel similar to latex surface; good air permeability and flame retardant properties. At the same time, due to the short production cycle, high efficiency and low energy consumption, it has replaced the traditional heat-cured polyurethane foam. At present, there are many large-scale professional PU manufacturers in China. The high-resilience sponge has good durability, and the high-density material ensures that it has strong durability and strong support. This stress-relieving property avoids the pain and discomfort often caused by rebound pressure or gravity self-build. For example, the high-elastic sponge of the sofa cushion can maintain the resilience of the sofa, which is comfortable and not easy to deform. The function is to be more compressive and more comfortable, because the diameter of the sofa cushion high-elastic sponge is mixed in size, the thickness of the skeleton is different, and there is a large opening rate. , Therefore, sofas, cushions and mattresses made of high-resilience foam can provide better comfort, that is, a more ideal comfort factor, and are ideal materials for car seats, sofa seats and office seats. What is the main purpose of high resilience sponge? High resilience sponge also has a wide range of uses in the furniture industry, aircraft industry, toy industry, automobile, motorcycle, train, sporting goods industry (mainly sports protective gear) and other industrial fields. Among them, there are motorcycle cushions, car headrests, backrests, sofa cushions, mattresses, car seats, sofa seats, office seats, toys, massage equipment accessories, high-density balls, and one-time molding sponges of various shapes.

Memory foam overview: Memory foam is a polyether polyurethane foam sponge with slow rebound mechanical properties. It is a special sponge developed by a European company. The common English name is MEMORY FOAM, and memory foam is its literal translation. In China, it is also called slow rebound sponge, zero pressure sponge, aerospace cotton, TEMPUR material, low rebound sponge, viscoelastic sponge, slow elastic sponge, inert sponge, etc. . Memory foam is a polyurethane foam with slow rebound properties. It was originally designed by NASA’s Ames Research Center to relieve astronauts from the enormous stress that astronauts put on during the spacecraft’s cosmic acceleration. Ames Research Center authorized a European company in the 1890s to develop and introduce it into the civilian category twice, in medicine, and later into household products. After being widely recognized abroad, it has appeared in China in the past 10 years. Memory foam application: Due to the difficulty and high cost of production, the main application of memory foam is to protect the human body, and it can be found in modern equipment and expensive products. For example, in the fields of extremely high-speed aerospace and aviation, it exerts its ability to absorb kinetic energy and shock; in static environments, such as sleep, sitting, etc., its deformation is required to balance the contact pressure of the weight-bearing surface and maintain the blood circulation of soft tissues. Desired low pressure environment; provides gentle support in a postural maintenance environment. The promotion rate of memory foam is proportional to the consumption capacity of a country/region. The application of memory foam is very popular in developed countries, and it is just beginning in developing countries. In China, the proportion of consumer goods in developed coastal cities is relatively high. Among the applied products, memory foam pillows are one of the to be promoted. Memory foam features: * In terms of mechanics, such as absorbing impact force, reducing vibration, and releasing low rebound force, it is a buffer material to protect the astronaut’s body when the space capsule is landing, and it is a material for the packaging of valuable instruments. * Provides uniform surface pressure distribution; adapts to the surface shape of external pressure through stress relaxation, so that the pressure at high points is reduced to a low level, thereby avoiding parts with microcirculation pressure. Maintains the shape of foreign objects and is a good material for posture mats. * 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; no country has announced that it does not meet the hygiene and safety testing requirements of daily necessities. * The transparent cell structure ensures the breathability and hygroscopicity required by human skin without perforating, and has proper thermal insulation performance; it feels warmer in winter and cooler than ordinary sponges in summer. * It has antibacterial, anti-mite, anti-corrosion, strong adsorption capacity, and maintains the cleanliness of the outside world; generally, it can be used for a long time without cleaning or exposure to the sun when it comes into contact with the human body. * It is more durable and maintains performance for a long time; it can be arbitrarily shaped as needed; it can be made according to the required hardness, rebound speed, and density to meet the needs of products for different purposes; the human body feels very comfortable, etc.

There are basically three ways we can think of to reliably disinfect kitchen sponges: Immersion in a suitable liquid disinfectant solution for suitable amounts of time. ‘Suitable time span’ will depend on the product used and a slew of other factors. Some candidates: Chlorine based products (aka bleach) Alcohol based products (usually relying on ethanol or isopropyl as the active ingredient) Hydrogen Peroxide solutions All sorts of commercially made products based on other microbicides. Exposure to heat above a certain temperature for a certain time. Again, times and temperatures vary. Some ways to achieve that: Immersion in boiling water for a couple of minutes Immersion in hot-but-not-boiling water (above 85°C) for a quarter hour or so Exposure to saturated/superheated steam for certain lengths of time. Pressure cookers, commercial food steamers, medical autoclaves come to mind as workable devices for that. Exposure to dry heat. Ovens etc. You'd probably need temperatures that will degrade the sponges’ material for reliable results, though. Exposure to radiation. Alpha, Beta or Gamma rays are probably out of the question, high intensity X-rays don't strike me as a viable alternative, either. Microwaves? Maybe. I'd hate to have to figure out a reliable method for using a consumer-grade microwave oven for the purpose, though. Ultraviolet works great for surface disinfection, but I wouldn't bet fuck all on kitchen sponges being UV permeable. Or a mix of the above. A 95°C washing cycle with somewhat aggressive laundry detergent will do the trick, as may a trip through the dishwasher, for example. In practical terms? The things are disposable items. Use them till they're grubby, store ’em on a well-ventilated rack during that time and throw them out when they start being yucky. Also, unless your procedure for washing dishes is seriously messed up, they don't need to be sterile. They're used to scrub off solid-ish residue, the final rinse under hot water should be what gets rid of harmful bacteria on your dishes. If you're paranoid about germs (which you really shouldn't be), sterilize your dishes after washing up, not your dishwashing sponges.

Sponges do not have nervous, digestive or circulatory systems. Instead, rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes. Sponges are animals that belong to the phylum Porifera, which means "pore bearer." The name fits them ly, since their rigid bodies are covered with small holes. Sponges are unique members of the animal kingdom. They possess several traits that set them apart from other aquatic wildlife. Sponges have no nervous system or organs like animals do. This means they don't have eyes, ears or the ability to physically feel anything. However, they do have specialized cells that carry out different functions within their bodies. While adult sponges are not mobile, they are able to react to certain physical stimuli despite lacking conventional organs and sensory systems. Sponges have no nerves or brain, so they lack any ability to cognitively control their movement. Their simple anatomy is similar to that of the earliest members of the animal kingdom. Since sponges have no true sensory organs, they aren't capable of hunting prey. Luckily, they don't have to move to find food. These animals grow on hard surfaces along the ground beneath oceans, lakes and bodies of water. The pores that cover their bodies are filled with specialized cells called choanocytes. These cells are equipped with small tentacles called flagellae that whip back and forth to pull water into the sponge's body. The sponge filters small organisms, like bacteria and plankton, out of the water and consumes them through a process of phagocytosis, according to Animal Diversity Web. Sponges lack blood or a circulatory system, so each cell digests and processes food individually. Sponges can't digest everything they find in the water, so they expel or "vomit" these inedible particles. Some researchers compare the process to sneezing, since the water and inedible matter is expelled through a rapid bodily contraction throughout the sponge. While scientists don't fully understand the mechanism that allows sponges to coordinate a bodily contraction, they have found that fluctuating calcium levels throughout the body are associated with the reflex, according to the Society for Integrative and Comparative Biology. A rapid succession of spikes and drops in calcium level occur during the sneezing reflex in some sponge species. Sponges are hermaphrodites, so they aren't restricted by gender. Each organism can act as a male or female and may change roles on the next reproductive cycle. Sponges can reproduce sexually with other individuals or procreate asexually. Each fertilized egg develops into a free-floating sphere of cells called a blastula. The baby sponge floats freely in the water for weeks or months before settling down and developing into an adult sponge. Larval sponges lack organs and sensory systems just like adults, but they are considerably more mobile and can travel great distances on water currents before establishing themselves. All of them attach to solid matter in order to grow and thrive. They are covered in ostia, which are pores that into their bodies. These pores play a critical role in their survival by allowing the entrance of food and water into their systems.

Nano sponge is also called nano sponge, beautiful nano sponge, melamine sponge, decontamination sponge or magic sponge. It is a special open-cell structure foam body developed by new nano technology. It is a new type of environmentally friendly cleaning product in the 21st century. Harmful properties; each small particle is smaller than 1/10,000th the size of a human hair.
