Do you know all about the auditorium seat cushion sponge?

The seat cushion is one of the most frequently used parts of the auditorium chair. People sit on the auditorium chair and are supported by the seat cushion, and the seat cushion is mainly composed of sponge. Today, let's learn about the auditorium seat cushion from the common problems of the auditorium seat cushion, the production process of the seat cushion sponge and the structure of the seat cushion.

1. Common problems of auditorium seat cushions:

A common problem with auditorium seat cushions is that the seat cushion collapses. After sitting down, the seat cushion will not automatically recover. Many people think that this is the seat cushion damage caused by the fatigue of the spring. In fact, it is not. Most of the real reasons are: the seat After a long time of pressure, the cushion sponge is caused by weak elasticity, and some of it is also because the quality of the foam is too poor, it is easy to have no elasticity, and it cannot provide effective support pressure.

2. The production process of the auditorium seat cushion sponge:

First of all, what is sponge? The sponge is mixed with an appropriate amount of polyurethane and a foaming agent, and placed in a closed mold, the foaming agent causes a reaction, so that the resin expands and fills the mold cavity. The production of the 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 closely and comfortably with the body.

3. The structure of auditorium seat cushion:

The first layer is silk cotton, which can isolate the moisture and moisture from the fabric, preventing moisture from damaging the sponge at the base layer, and the second layer is a soft high-density sponge, which provides the occupants with a comfortable and fit sitting feeling. The third layer is a rigid high-density sponge with tight elasticity.
