Sponge manufacturing process:
A. Mix foaming resin, foaming agent and adhesive resin (to make the finished product adhesive) together;
B. For foaming processing. The foam sponge was prepared by mixing 80 parts of vinyl acetate (EVA), 20 parts of APAO PT 3385, 20 parts of azodicaramide, l9 parts of CaCO and 0.6 parts of diisopropylbenzene peroxide into a mold for foaming, and breaking the obturator cell by mechanical force. Its density (d) is 0.028 g/cm and its 25% compression hardness is 1.9 KPa.
The main ingredients of sponge: people commonly used sponge is made of wood cellulose fiber or foam plastic polymer. In addition, there are natural sponges made from sponges. Most natural sponges are used for body cleaning or painting. There are three other types of synthetic sponges: low-density polyethers (non-absorbent sponges), polyvinyl alcohol (highly absorbent materials with no obvious pores) and polyester.
