1, microwave sponge
Soak the sponge in water and put it in the safe bowl of the microwave oven. Rinse the sponge under tap water for 30 seconds to make it completely saturated. Don't squeeze or wring out the sponge, because you should keep it as much as possible. Put the wet sponge into glass, plastic or ceramic bowls, which can be safely put into the microwave oven. Microwave sponge 1~2 minutes.
Step 2 soak and clean the sponge
Prepare 10% bleach solution in a bowl. Add 9 parts water and 1 part bleach to a glass, plastic or ceramic bowl and thoroughly stir the mixture. Make sure there is enough solution to completely immerse the sponge in water. Soak the sponge in bleach for 5~ 10 minutes, and then clean it.
Introduction of sponge materials:
Sponges are made of wood fibers or foamed plastic polymers. Sponge is a porous material with good water absorption, which can be widely used to make sofas, mattresses, boss chairs and sports equipment, such as sponge gymnastics mats, sponge fitness mats, sponge wrestling mats, sponge car cushions and other products. In addition to lignocellulosic fibers, there are three kinds of synthetic sponges made of other materials, namely low-density polyether, polyvinyl alcohol and polyester.
Sponge is a kind of foamed polymer. Sponge has fine structure, smooth surface and soft and elastic feel. It has good cushioning, earthquake resistance, heat insulation, moisture resistance, chemical corrosion resistance, non-toxic, tasteless, water absorption and other characteristics, which can effectively prevent products from being impacted during transportation, and does not contain polluting chemistry and denaturation plasticity.
