Most of the software furniture, such as mattresses and sofas, uses a very important material - sponge. Sponges are divided into many types. The primary color of the sponge is beige, but it often turns yellow due to oxidation reaction with oxygen, and some are bleached into white or dyed as needed. The sponge is soft and has heat preservation, heat insulation, sound absorption, shock absorption and flame retardancy. , anti-static, good ventilation and other characteristics, according to the size of the inner bubble, can reflect a variety of density, can be molded into various shapes according to needs, a large number of applications in various industries, mainly used For shockproof, heat preservation, material filling, etc. The types of sponges are classified into polyester sponges and polyether sponges. Polyester sponges are high-pressure sealing foams, and polyether sponges are box-type foaming. Most of the components of the sponge are polyurethane. Polyurethane is the most common polymer material in life and is widely used in the production of various "sponge" products. As well as suspension and anti-friction elastic materials, such as soles, tractor tank track substrates. There are many kinds of sponges used in industrial production, such as foaming cotton, shaping cotton, rubber cotton, and memory cotton. Polyether foam hair foam molding, foam like bread like. It can be foamed by mechanical equipment or artificially surrounded by wood. The foamed cotton is like a square loaf. The slicer is used to cut the thickness according to different requirements. The foam can also adjust the hardness. . The seat cotton is generally 25~28kg/m3, and the other is 20~22kg/m3 density. Although the softness and density of the sponge are directly related, they are also related to different additive formulations. Therefore, the industry is divided into high elasticity, gray super, black gray and soft cotton. When designing and using the product, it should be rationally and scientifically matched according to different shapes and structures. Generally, the sponges with different elasticity and density are matched with the upper, middle and lower parts. There is a kind of sponge called fire-retardant material (flame-retardant cotton). In fact, before the foam is foamed, a fire-preventing agent is added to the material formula. For example, chlorine and bromine can cause the sponge to ignite when it is on fire, and it plays a flame retardant role. The shaped cotton is mixed with various additives such as a foaming agent and a foaming agent. The pressing agent can be pressed into a simple mold to press out the sponge of different shapes. It is suitable for the swivel chair seat cushion, back cotton, and also has a small amount of handrails. Cotton. At present, the density of materials used is 55#~60#, and its elasticity is in line with relevant national standards. The elastic hardness of the sponge can be adjusted and adjusted according to different parts of the product. Generally, the seat has a higher hardness, a higher density, a second back, and a softer pillow. Rubber wadding is also a kind of sponge. It is made of natural latex raw material. It has rubber characteristics, excellent elasticity, good resilience and no deformation, but it is expensive and higher than foaming. ~4 times. Stainless Steel Kitchenware is absolutely everywhere in the kitchen. If you don't have sleek stainless steel appliances or kitchen islands, you probably have stainless steel pans, mixing bowls, and utensils. Ever wonder how stainless steel came to be so universal in cooking? One hint: it's more than just it's pretty looks.

Steel is fantastic stuff. It's an iron alloy and strong as all get-out. It doesn't chip, bend, or crack easily (though it does scratch), and it stays shiny over years of use.
Just one problem: it rusts. Enter stainless steel.
Stainless steel is a metal alloy with about 10-11% chromium. When exposed to air, the chromium in the metal forms a film of chromium oxide over the surface. This film is passive and non-toxic, and most importantly, it prevents the steel from rusting by shielding it from air and moisture. Even if the metal gets scratched, the chromium oxide reforms seamlessly.
This gives us all the excellent properties of Stainless Steel KitchenWare without the worry of rust. It's also non-reactive, unlike aluminum and iron, so we can use it for preparing and cooking acidic foods.
Simply put, we use stainless steel kitchenware in the kitchen because it's one of the most durable, versatile, and worry-free metals available. It's hard to argue with that!
