1. Introduction of high-density foam sofa cushions
1. Sponge sofa cushion is a kind of sofa cushion with sponge, and the outer layer is usually wrapped with cloth and leather. The quality of high-density foam sofa cushion is better in sponge sofa cushion. High-density foam is a kind of sponge, which weighs more than 45 kilograms per cubic meter.
2. Now that the sponge technology has improved, it is no longer possible to judge the density of the sponge simply by weight. The sponge of the method of the present invention has a high density and a much lighter weight than the previously processed sponge.
3. The density of high-density foam cannot be judged by weight alone. Generally speaking, the hardness of high-density foams is also very high, but it is not excluded that some high-density foams will add super-soft additives to make sponges super-soft, which can be used as sound-absorbing cotton, sofa cushions, soft bags and other materials. Medium density and low density sponges are used as general protective materials. Sponges with the same density have different hardness.
Second, the advantages of high-density foam sofa cushions
1. Usually, the sponge density of sofa cushions is around 35, including soft, hard and super soft. Mattresses are generally around 22 feet. High-density foam is porous and plump, with the characteristics of absorbing external force, delicate touch, softness and comfort. Although the sitting feeling is a little hard, it is not easy to deform. It is heavier than the low-density sponge sofa cushion and is usually not used for water absorption. The high-density foam sofa cushion has high elasticity and elasticity when pressed by hand.
2. You can choose a sponge cushion for the sofa at home, but you must choose the whole sponge. If it is a cushion made of broken sponge, there may be problems such as depression, deformation and suspension of the cushion during use. The service life of the cushion may only be 3-5 years, and some foamed rubber or adhesive will be filled inside, which will produce odor and endanger human health. Check whether the whole sponge can be lightly pressed on the surface of the cushion by hand and gently slid to check whether the surface is smooth and seamless. You can also pick up the cushion and unzip sofa cover to see if the lining bag is flat and wrinkle-free. If the filled sponges are spliced, there will be color difference and splicing marks between sponges, which can be seen through the lining.
Third, the types of high-density foam sofa cushions
Sponges mainly include A cotton, pink super, super soft super, blue super, gray high elastic, white elastic, green high elastic, yellow high elastic, colored red plastic, PU plastic and so on.
1. Cotton: density 13KG/ m3, used for fixing the bottom, with a wooden frame covering a layer of surface;
2.PinkSuper: the density of handrails and backrest is 25 kg/m3;
3. Super soft and super; The density of the backrest is 36kg/m3;
4. Orchid: the density is 30KG/m3, which is used for foundation and cushion without stress center;
5. High ash bomb: density 35KG/ m3, used for seat cushion;
6. White bullet: the density is 35KG/m3, which is used for cushion, and its elasticity is better than that of gray high bullet;
7. Green high elasticity, yellow high elasticity: the density is 40KG/m3, and the high-grade sofa cushion sponge is superior to white elasticity;
8. Rainbow bomb: also known as violet, density 27KG/ m3, mainly used for backrest, super soft.
9. One of the characteristics of doll cotton silk cotton is its smoothness and elasticity. Mainly used for fabric sofas, backrests and pillows. Suitable for soft sofas.
Features of sofa sponge material for sofa renovation: using sofa frame and 3cmA cotton (sponge thickness of several enterprises is 1.5-2cm) to make the sofa smoother; The sponges on the cushion, especially the high elastic sponges with different densities, are superimposed to make the comfort, elasticity and durability of the cushion reach the best balance point. The density of the top floor is 45 to ensure a comfortable and warm sitting posture, and the density of the middle floor is 40. Sponge is used to control the elasticity of the cushion, and the lower layer uses a sponge with a density of 35 to increase the pressure of the cushion, making the cushion more durable.
The above is the introduction of high-density foam sofa cushions that we brought to you.
