How to distinguish the quality of packing sponge? Let's talk about it briefly. Sponge can be distinguished from the following aspects:
1. Rebound rate, rebound rate mainly depends on the density, the higher the density, the easier the rebound.
2. The compression deformation rate is better than 5%, the second is less than 7%, and the difference is less than 10%.
3. It depends on the mechanical property requirements. Mechanical property requirements are professional terms. In terms of language we can understand, it means how many times people can sit. Generally, it is 60000 times, followed by 40000 times, and the worse is 20000 times.
Generally, the sofa with density is suitable for high elastic sponge. This material can improve the comfort of sitting and sleeping. Some foam also make soft treatment while ensuring that the density is not reduced. Some use the built-in spring, which will make the sofa elastic better and delay the aging degree.
