Sponge manufacturers take you to understand what are the main characteristics of sponge column:
The surface of the film, so that it is reasonably completely isolated from the external gas, so the water vapor can not pass through, do not need to enhance the vapor barrier layer, the surface is not easy to condense water, low water absorption.
⑤ The available temperature has a wide operating scale, excellent cold resistance, and will not become hard and brittle at -40°C.
It is no chlorine and no synthetic fiber, not easy to cause allergies.
⑦ It has the strong essence of expanding ups and downs, can withstand the transmission of involved and rough force, and is not easy to be destroyed under strong conditions.
The shock absorber, sound insulation effect is good, the available business scale is universal.
⑩ soft touch, good ductility, high compressive strength, smooth surface, simple equipment, economic development, convenient, beautiful and neat, clean.

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.
