Do you know all about the knowledge of auditorium chair seat cushion sponge?

The seat cushion is one of the most frequently used parts of the auditorium chair. People sitting on the auditorium chair rely on the seat cushion for support, and the composition of the seat cushion is mainly sponge. Today, let's learn about the knowledge of auditorium chair seat cushions from three aspects: common problems of auditorium chair seat cushions, the production process of seat cushion sponge and the structure of seat cushions!

1. Common problems of auditorium chair seat cushions:

A common problem of auditorium chair seat cushions is seat cushion collapse. After sitting down, the seat cushion will not automatically recover. Many people think that this is caused by spring fatigue. In fact, it is not. Most of the real reasons are: the seat cushion sponge has been under long-term pressure and elasticity is weak. Some of them are also because the quality of the foam is too poor, it is easy to have no elasticity and cannot provide effective support pressure.

2. The production process of auditorium chair seat sponge:

First of all, what is sponge? Sponge is made by mixing polyurethane and foaming agent in appropriate amounts, putting it into a closed mold to cause the foaming agent to react, causing the resin to expand and fill the mold cavity. After the reaction is completed, it is taken out to form a sponge. The production of sponge will lead to the final quality of the sponge. The sponge has high density, better elasticity, long-lasting pressure resistance, and softness that can fit tightly and comfortably with the body.

3. The structure of the auditorium chair cushion:

The first layer is silk cotton, which can isolate the moisture and water conducted by the fabric, and prevent moisture from damaging the base sponge. The second layer is a soft high-density sponge, which provides passengers with a comfortable and fitting sitting feeling. The third layer is a hard high-density sponge with firm elasticity.
