1. Material difference: The raw material of latex is natural oak sap, which is formed by foaming to generate pores. Memory foam is also called slow rebound sponge. The raw material is extracted from petroleum, and it is mainly chemical synthesis. 2. Different lifespans: Latex will not deform for 15 years normally. After 2 to 5 years of memory foam, the position where you often sleep will not rebound. 3. Different rebound: Latex rebounds immediately, while memory foam rebounds slowly. 4. Different touch: Latex has the same good touch and close-fitting effect in all seasons. Memory foam is hard in winter and soft in summer. 5. Different functions: the oak protein of latex itself can inhibit the breeding of mites, and the memory foam has strong shock absorption ability, which is suitable for decorative materials, shock absorption materials and sound insulation materials. The memory pillow is made of slow rebound material. The so-called slow rebound means that when a certain pressure is applied to it, it will not be deformed immediately like sponge, but has a certain “memory” function. , can maintain the elastic deformation of 3-5S, maybe you can’t understand this characteristic, but if you understand the 6G pressure that the astronauts bear in the process of going up and down physically, you will understand the benefits of this material . The slow-rebound memory foam material also has a “memory” function, which is its temperature-sensing feature, which has a strong affinity for people and can quickly integrate with the human body. Using memory health care pillows will not feel any It also has a certain repairing effect on patients with cervical spondylosis. The natural latex pillow is a pillow made of pure natural materials, which does not cause any harm to the human body, and because of its unique natural material, it can effectively inhibit bacteria and mites, and has no side effects on the human body.

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.

Environmentally friendly sponge is made of many chemical substances polymerized. Its main chemical component is polyurethane, which is a kind of polymer material, so it will produce a lot of irritating gas during chemical reaction, which is a toxic substance. Environmentally friendly sponges require that there is no such toxic substances in the sponges, and they can be decomposed. This kind of environmentally friendly sponges is mainly used for cleaning and bathing. The main component is composed of wood pulp fibers, which can absorb water and decompose naturally. Yes, it can fully comply with the EU rosh environmental certification and the US UL certification. Environmentally friendly sponges are different from ordinary sponges in terms of composition.

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.
