Where is the advantage of high density sponge sofa cushion:
② Now the sponge processing technology has been improved, has been unable to independently according to the net weight to distinguish the relative density of sponge. The sponge of this product method has a high density and a much lighter net weight than the sponge previously produced and processed.
High density sponge sofa cushion advantage:
① In general, the relative density of sponge sofa cushion is about 35, and soft, hard, super soft and so on. The mattress is generally about 22 inches. High-density sponge has a porous structure, plump, with digestion and absorption of external forces, delicate touch, soft and comfortable characteristics. Although it feels slightly stiff, it is not easy to deform and is heavier than a low-density sponge sofa cushion, and is generally not used to absorb moisture. High-density sponge sofa cushion with high elasticity, but also in the hands of light on time with elastic force.
② You can choose cotton pads for home sofas, but you must choose all the sponge. If it is a cushion made of crushed sponge, it is likely to cause problems such as dents, deformation and cushion suspension during the application period. The use period of the cushion is likely to be only 3-5 years, and the interior will be filled with some foaming vulcanized rubber or adhesive, which will cause smell and endanger health. Check whether a whole sponge can be gently pressed on the surface of the cushion and gently dragged to check whether the surface is flat and has no seams. You can also take out the cushion and drive the zipper of the sofa cover to see if the liner is flat and wrinkle-free. If the added sponge is pieced together, there may be a color deviation and patchwork marks in the middle of the sponge, which can be seen according to the lining.

Compared with artificial sponges, natural sponges do not have static electricity that hurts the human body, do not peel off and last long. The sponge that lives in the sea is the real sponge, and the artificial "sponge" just imitates the structure of the natural sponge. Natural sponges that live in seawater are mostly grayish yellow, brown or black lumps. Its body surface has many bulges, there are many small holes beside the bulge, and there is a large hole at the top of the bulge. Seawater flows in from small holes and out from large holes, and those tiny creatures enter the sponge with the water and become "self-contained" food. Therefore, although the sponge is called "the flowers and fruits of the sea", it looks like a plant, but it is actually an animal.

You will surely find that the plush toys are clean. The crude salt removed became gray-black due to the adsorption of dirt. The principle is the use of salt that is sodium chloride adsorption of dirt. Soda powder can also be used instead of coarse salt, the same usage. This method is more suitable for large plush toys and plush toys that can not be washed with sound.
The main ingredient of the sponge?
Polyurethane soft foam rubber, polyurethane is one of the most common polymer materials in life, widely used in the production of various "sponge" products. Now there are three kinds of sponges on the market, 1: polyurethane type, burning to generate a large number of cyano-containing gases, these gases are very toxic and suffocating. 2: polyethylene type, combustion of carbon-containing gas, this kind of gas toxicity. 3: polystyrene type, this kind of foam burning decomposition of a small amount of styrene monomer, toxic, but not as toxic as polyurethane.
