Abstract: |
The dispersity of black N330 in non-sulfur modified powdered CR/N330[P(CR/N330)]was investigated.The results showed that the dispersity of black N330 in P(CR/N330) improved significantly by using the encapsulant and increasing the addition level of dispersing agent,thus the contact staining of P(CR/N330) was reduced or eliminated;and the contact staining of P(CR/N330) resulted from the free carbon black crumbs in the P(CR/N330) granules,especially on the surfaces of granules. |
