"Time is like water in a sponge, as long as you are willing to squeeze, there is always something", this is Lu Xun's famous saying.
Lu Xun's analogy is very appropriate, we all know that the sponge's ability to absorb water is very strong, when you squeeze the water in the sponge, when you think there is no time, and then squeeze hard, there will still be time, time is like water in the sponge, is squeezed out. As long as you can squeeze, use and drill, time will definitely be there.
Speaking of sponges, sponges are many types of sponges, foam sponges, wave sponges, shaped sponges, shaped sponges, PU sponges, sheet sponges, rolled sponges,stainless steel sponge sound-absorbing sponges cellular sponges, sponge machining, sponge CNC cutting processing, rubber sponges, memory sponges, and so on, the characteristics of the sponges: environmentally friendly, fire prevention, self-skinned, high-density, antistatic, acoustic insulation, high-temperature, high resilience, slow rebound, hydrophilic, strong tensile force, conductive, etc., and more! Applications: packaging, electronics, filtration, footwear, handbags, toys, furniture, horn drum paper, sun hats, sanding, sealing, bags and so on. Guangdong Jiasheng Sponge Co., Ltd. provides wholesale, customized and direct sponge supply service.
Red Wave Sponge
Styling sponge is made of polyamino acid material by mixing various additives such as foaming agent and then pressed into a simple mold and heated. It is suitable for swivel chairs, sofa seat cushions and back cushions and other parts. The density of sponge is the biggest standard to measure its advantages and disadvantages, because the density reflects how much material is used in the unit cubic sponge. At present, the stereotyped sponge with 55#~60# material density meets the relevant national standards. Sponge elastic hardness can be adjusted according to different parts of the product. General seat sponge is harder and denser, back sponge is second, armrest is softer.
Foam sponge is molded from polyether foam, like foamed bread. You can use mechanical equipment for foaming can also be manually using wooden boards around the foam. After foaming, the sponge is like a big square bread. After the slicing process using a slicer, the thickness is cut according to different requirements. The softness of the foam can also be adjusted.

The softness of the sponge and the density of the sponge is directly related, but also with different additives formula has a relationship. Therefore, the industry is divided into high elasticity, gray super, black gray super, soft cotton and other types. Product design and use should be based on different shapes and structures for reasonable and scientific collocation. Generally speaking, the upper, middle and lower three parts of the sponge should be matched with different elasticity and density of the sponge. Sponge has a material called fireproof sheep, it is in the sponge foam before the fireproof agent added to the material formula. So that when the sponge is on fire can produce the role of extinguishing the fire smoke, and play a flame retardant role.
Rubber sponge is a type of sponge, it is made of natural latex raw material foam. It has the characteristics of rubber, excellent elasticity, good resilience and will not be deformed. However, the price is higher, three to five times higher than foam cotton.

Recycled sponge is a kind of material called "recycled cotton" in furniture products. In fact, it is made by extruding sponge scraps. The cost is low but the elasticity is poor and the density is not uniform. High-quality sponge is made of natural petroleum refining material. It is elastic, clean and odorless. The more pronounced the rebound is when it is held tightly in the hand and then released, the better. The low-quality recycled cotton is usually recycled and processed from sponge scraps. Dull color and pungent odor, feel brittle and hard.
Sponge in the sofa selection and application of materials
Ordinary sofa seat cushions generally use 25-30 kg per cubic meter of sponge material production, reclining bag is generally between 20-25 kg per cubic meter. Domestic sponge process can currently reach but not more than 35 kg per cubic meter density. More than 35 kg per cubic meter of products belong to the resin products, the cost is quite expensive. Generally used in airplane cockpit and famous car seat manufacturing. None of the domestic manufacturers have such strength to produce resin sofas. Imported resin sofas generally cost more than tens of thousands of dollars. In order to achieve high density requirements, domestic manufacturers add talcum powder in the production process. However, talcum powder processing uses a large number of ingredients containing formaldehyde and toluene, which are harmful to the human body. In addition, the addition of talc tends to cause shedding and seriously damage the service life and performance of the sea surface. When sitting on it, the sofa feels stiff and inelastic and the foam is brittle and falls off easily.
To improve sitting and sleeping comfort, the foam is softened to ensure that the density is not reduced. Some sofas have vertical springs in the seat cushions to increase resilience and ageing resistance. The quality of the foam depends on the density rather than the resilience or softness. The foaming process of a sponge is an interaction of several components. Therefore, a high resilience sample does not mean that the resilience performance is long-lasting and long-lasting. Many high rebound sponges on the market in the use of a year after the beginning of different degrees of collapse phenomenon is due to reduce the density in order to achieve a soft and short-term rebound performance effect. People often say that the sofa is softer and more comfortable is not entirely correct. How to choose the softness of the sofa that suits you? In addition to personal preference, it is also necessary to consider the user's height and weight, as well as the age of the two factors. First of all, according to the height and weight of the individual to consider the choice of seat spacious depth of the larger soft type of sofa; for the smaller weight of the person is better to choose a shallow depth of the sofa in order to prevent the feet do not touch the ground caused by the thighs numbness. As for the choice of sofa soft hardness can be based on weight and personal preferences to decide. Secondly, according to the age division to consider the choice of sofa soft hardness. Young people like sofas that are soft enough to relax the body's joints after a busy day, while the elderly and middle-aged people should choose a harder sofa to support their body weight and reduce the pressure on their joints due to the aging of their bones, which is not suitable for sitting on a soft sofa for a long period of time. Choose a comfortable sofa in addition to careful selection should also try to sit to ensure that it can reasonably support your center of gravity and conform to the principles of ergonomic design. Consumers are also reminded that when choosing a sofa, they should try several sitting positions and angles as well as the most relaxed position to experience the comfort of the sofa. Under normal circumstances, the human body after sitting down sofa cushion depression of about 10 centimeters and rebound rate of 60% or more for the best state.
