What do you know about auditorium seating cushion sponge knowledge?

The seat cushion is one of the most frequently used parts of the auditorium seating. People sitting on the auditorium seating are fully supported by the seat cushion, and the seat cushion is mainly composed of sponge. Today, let's learn about auditorium seating cushions from three aspects: the common problems of auditorium seating cushions, the production process of cushion sponges, and the structure of seat cushions!

1. Common problems of auditorium seating cushions:

The common problem of auditorium seating seat cushion is that the seat cushion collapses. After sitting down, the seat cushion is sunken and will not automatically recover. Many people think that this is the seat cushion damage caused by spring fatigue, but it is not. Most of the real reasons are: seat The cushion sponge is caused by weak elasticity after long-term pressure, but it is not ruled out that some auditorium seatings have poor quality cushion sponges and easily lose elasticity, which cannot provide effective support pressure for the human body.

2. The production process of auditorium seating cushion sponge:

First, what is sponge? Most auditorium seating seat cushion sponges are mixed with polyurethane and foaming agent in an appropriate amount, put into the closed mold, and the foaming agent reacts to make the resin expand and fill the mold cavity. After the reaction is completed, it is taken out to become a sponge. The production of the sponge is an important factor affecting the final quality of the sponge. The density of the sponge is high, the elasticity is better, the pressure is durable, and the softness can fit the body closely and comfortably.

3. The structure of auditorium seating cushion:

The first layer is silk cotton, which can isolate the moisture and moisture transmitted by the fabric, and prevent moisture from damaging the sponge on the base layer. The second layer is soft high-density sponge, which is mainly used to give the occupants a comfortable and fit seat. The third layer is a hard high-density sponge, which is elastic and firm.
