Sponge
"Time is like water in a sponge, as long as you are willing to squeeze, there is always something", is Lu Xun's famous saying.
Lu Xun's analogy is quite appropriate, we all know that the sponge has a strong ability to absorb water, when squeezing the water in the sponge, when you think there is no, then squeeze hard, there will still be, time is like the water in the sponge, is squeezed out. As long as you can squeeze, use, drill, time will definitely be available.
Speaking of sponges, there are many types of sponges, foam sponges, wave sponges, stereotyped sponges, special-shaped sponges, PU sponges, sheet sponges, roll sponges, sound-absorbing sponges honeycomb sponges, sponge processing, sponge CNC cutting processing, rubber sponges, memory sponges, etc., its characteristics: environmental protection, fire prevention, self-crust, high density, anti-static, sound insulation, high temperature resistance, high rebound, slow rebound, hydrophilic, strong pull, conductive, etc., more used in: packaging, electronics, filtering, shoe materials, handbags, toys, furniture, trumpet drum paper, sun hat, polishing , seals, bags, etc. Sponge wholesale, customized, direct supply which is strong, Guangdong Jiasheng Sponge Co., Ltd. for your navigation.
Red wavy sponge
Stereotyped sponge, by polyine materials, through the foaming agent and other additives mixed, the pressure agent into the simple mold heating can be pressed out of different shapes of sponge, it is suitable for swivel chairs, sofa seat cushions, back cotton, there are also a small number of armrests are also made of stereotyped cotton. Sponge density is the largest standard to measure its advantages and disadvantages, because the density reflects the amount of material used in the unit cubic sponge, at present, the density of 55# ~ 60# material is used, and its elasticity is more in line with the relevant national standards. The elastic hardness of the sponge can be adjusted, and it can be adjusted according to different parts of the product. Generally, the seat cotton is harder and denser, followed by the back cotton, and the shan sponge is softer.
Foam sponge, formed from polyether foam, like foamed bread. Can be used mechanical equipment foaming can also be manually surrounded by wooden boards to foam, foamed cotton like a square bread, the use of slicers through the slicing process, according to different requirements to cut the thickness, foam cotton can also adjust the softness and hardness.
Black acoustic foam
Although the softness and density of the sponge are directly related, they are also related to different additive formulations, so the industry is divided into high elasticity, gray super, black gray ultra, soft cotton. When the product is designed and used, it should be reasonably scientifically matched according to different shapes and structures, and the sponges with different elasticity and density are generally divided into three parts: upper, middle and lower. There is a kind of sponge called fireproof cotton material, in fact, before the sponge foams, the material formula is added with fireproof agents, such as chlorine and bromine so that the sponge can produce fire smoke when it catches fire, which plays a flame retardant role.
Rubber sponge, one of the sponges, it is made of natural latex raw materials, it has rubber characteristics, excellent elasticity, good resilience, will not deform, but the price is not cheap, three to five times higher than foam cotton.
Yellow baby cushion sponge
Recycled sponge, there is a kind of furniture product called "recycled cotton", in fact, it is squeezed together by sea cotton scraps. The cost is extremely low, but the elasticity is extremely poor, and the density varies. High-quality sponge is made of natural petroleum refining, the material is elastic, clean, tasteless, with the hand tight and then released, the more obvious the rebound, the better, and the low recycled cotton, mostly recycled by the sponge scrap recycling processing, the color is dark and pungent, the feel is crisp and hard.
Sponges are used in the selection and use of sofas
Ordinary sofa sponge cushion 25-30 kg per cubic meter, by the bag is generally 20-25 kg per cubic meter, the current density of domestic sponge can reach but not more than 35, more than 35 for gum products, resin products cost is quite expensive, generally used for aircraft cockpits and famous car seats, domestic manufacturers do not have such a strength, imported resin sofas are generally priced at more than tens of thousands of yuan. In order to achieve its density, domestic manufacturers add talc powder in the production process, talc powder processing processing use a lot of formaldehyde, toluene and other deadly components to the human body, and add talc powder, it is easy to fall off, while seriously damaging the service life and performance of the sea surface. Sitting on it, the sofa is stiff and inelastic, and the sponge is brittle, and it is easy to fall off by hand.
To improve sitting and lying comfort, the foam is soft treated to ensure that the density is not reduced. Some have vertical springs in the seat cushion to give the sofa a higher resilience and anti-aging performance, and the quality of the sponge depends on the density rather than its resilience or softness. Sponge in the foaming process is a process of interaction between a variety of components, so the high rebound sample force does not mean that the rebound performance can last for a long time and have a long service life. Many high-resilience sponges in the market often begin to collapse to varying degrees after one year of use, because of reduced density, to achieve a soft sitting feeling, short-term rebound good performance. People often say that the softer the sofa, the more comfortable it is, but this is not entirely the case. How to choose a sofa with softness and hardness that suits you? In addition to personal preferences, it is mainly from the user's height and weight and age factors. Factor one: considering the height and weight of the individual. Taller, heavier people should choose a spacious seat. Deeper and larger soft sofa; smaller, lighter weight people are best to choose a lighter sofa to prevent the feet from touching the ground, because the sponge of the sofa seat supports the gravity of the thighs, the thighs feel numb for a long time, as for the choice of sofa softness and hardness, you can decide according to weight and personal preferences. Factor two: consider from the age division. Young people like softer sofas, busy days outside, every joint of the body needs to be easily stretched, at this time sitting on a soft and comfortable sofa is the most suitable. And middle-aged and elderly body. The bones are older than those of young people, and it is not suitable for sitting on a soft sofa for a long time, and a harder sofa should be chosen. Choose a comfortable sofa to sit on, in addition to careful selection, should try to sit, the sofa is ergonomically designed, in line with the function of supporting the human center of gravity, consumers are best to try to sit for 10 minutes to truly experience whether this sofa can reasonably support your center of gravity. At the same time, consumers should be reminded to change a few more sitting positions and angles and their most relaxed methods when choosing a sofa. Under normal circumstances, the sofa cushion after the human body sits down to a rebound rate of more than 60% after the depression of about 10 cm.
