Sponge products have many titles, such as sponge products, engineering blasting sponge, perforated sponge and net-shaped sponge, which are all kinds of sponge products. So, for sponge products, there are some friends who know its definition and application. If there are friends who are not clear about it, then I will tell you.
Sponge products can be divided into air purification sponge, activated carbon, waste water, porcelain, colorful, cleaning, oil and other anti-fouling sponge and foam according to their characteristics and functions. The opening rate of sponge products is above 97%, with excellent air permeability, excellent flexibility and high impact toughness.
Sponge products are suitable for speakers, filter equipment, audio speakers, filter elements, aquarium fish tanks, cars, protective masks, height-to-width ratio breathable cushions, central air conditioners, wiping appliances, mattresses, model design, activated carbon filling, heaters and other commodities and their fields. Everyone knows that if you want to properly apply sponges, you must find out some key points of sponges.

Fabric sofa is mainly sponge and elastic yellow, sponge is divided into many kinds, professional terms are divided into many levels, now generally choose high density sponge, general finished products are difficult to see, only according to the test sit feel.
In addition, sponge products can be divided into thin, thick and hard and soft. The rate of thick sponge will be thinner and faster. As everyone's touch is different, when selecting the soft strength of sponge, it seems that it depends on my own opinion. Generally speaking, sponges that are too hard are used by fewer people, while young and child players are more suitable to use slightly softer sponges, because that can improve the feeling in their hands when serving.
