Life Nano teach you how to choose the quality compressed nano sponges(melamine sponge)
First step
Press the middle surface of the melamine sponge with the same strength,
Obviously feels that Life Nano-Plastic More resilient, the sponge's rebound feel is strong
Second step
Press the two side edge of the melamine sponge and the middle part
Life Nano-Plastic is flexibility
Other compressed nanofibers have a distinct hard layer
Third step
Press the middle of the side of the melamine sponge
Life Nano-Plastic is density
Other compressed melamine sponge are obviously too soft, and they are almost the same as ordinanry melamine sponge
Experimental results
Generally compressed nano-cotton usually presents two sides that are harder and softer in the middle.
The reason is that these processes are simple and can only compress sponges on both sides of the sponge, and the middle part cannot be compressed effectively. When the product is used, it is easy to delaminate from the middle. After the surface is worn, the sponge is as durable as an ordinary nano-sponge, easily damaged, and dregs off.
