do you know how to choose packing sponge:
Sponge, is a porous structure, with excellent water absorption capacity, can be used to clean objects. The common sponge is made of wood cellulose fiber or foamed polymer. In addition, there are also natural sponges made of sponges, most of which are used for human body cleaning or art painting. In addition, there are also three types of raw materials made of generated sponge, each of which is low density methacrylate (non-absorbent sponge), acrylic emulsion (high water absorption raw materials, no significant pores) and polyester.
The key to PU sponge includes polyester and methacrylate type, which can be cut into pieces or rolled, and can also be produced and processed according to customer regulations, pressed production and processing, and engineering blasting and drilling solutions. Because PU sponge has the characteristics of heat insulation, heat insulation, sound insulation, shock absorption, flame retardancy, antistatic, and good air permeability, it involves a variety of fields, including the automobile industry, rechargeable battery industrial production, Skin care products, chest size underwear processing and manufacturing, and high-end furniture processing and manufacturing.
3. packaging sponge good or bad choice
In the choice of packaging sponge, the key to its feel and ductility as the main elements of judgment. It should feel soft and malleable.
In addition, a specific identification method is to fold the packaging sponge and rub it with each other. If you drop the sponge crumbs without rubbing it twice, it's time to replace it.

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.
