furane

Shell carbon black can be used to modify furane resin for significantly enhancing its electrostatic resistance and impact resistance,so that it is of greater suitability value.

采用谢尔炭黑改性呋喃树脂，显著提高其抗静电、抗冲击性，有较大实用价值。

Compared with that of furane resin bonded sand,the feasibility of phenol resin bonded sand in forming a uniform coating layer in the inside mould surface is studied as well.
