Compressed sponge is made by pressing ordinary sponges at high temperature to achieve relative strength, relative density, and thickness. The compression ratio is different, and the strength and relative density will be different. The higher the engine compression ratio, the relative density The greater the strength.
Compressed sponge can be manufactured to 0.3MM thick. The materials can be determined according to customer regulations and main uses. At present, there are imported cotton (polyester sponge) and domestic cotton (methacrylate sponge). The key products are used in mobile phone headphones, audio speaker spare parts, electronic equipment and printer consumables, which have the effects of sound insulation, earthquake resistance, anti-fouling, sound correction, etc. Our company has complete types, rich experience, thin and well-proportioned thickness, and small dimensional tolerances for positive and negative electrodes. It is a technical professional manufacturer of compressed sponge in the field.
Compressed sponge features: strong ink absorption ability, good wear resistance, corrosion resistance, uniform ink, can be based on the need to produce a variety of relative density, specifications and models of goods. Compressed sponge is made by pressing ordinary sponges at high temperature to achieve relative strength, relative density, and thickness. The compression ratio is different, and the strength and relative density will be different. The higher the engine compression ratio, the relative density The greater the strength.

How to identify natural sponge and artificial sponge?
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.
Buy a pack of large salt or coarse salt, put the coarse salt and dirty plush toys into a larger plastic bag, and then fasten the mouth of the bag tightly and shake it vigorously. 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.
