RESEARCHES ON PROCESSING SEA FOAM AND APPLYING IT IN RUBBER

Sea roam ore in China is of low grade, about one fourth of foreign one. Owing to strong cohesiveness and water-absorption of sea foam, its concentration is difficult. According to the particularity of the primaryore, through its processing and surface activation treatment, the high-quality strengthening agent for rubber can bemade of it to replace the carbon black and white one. So that the application value of primary sea foam ore is lifted.
