Recently, rich sea (east battalion) the “ that dominant of limited company of new material science and technology finishs is high-powered get together development of technology of sulphone colophony key and applied ” project are evaluated through expert appraisal. Classics appraisal, achievement of this science and technology achieves international advanced level. This project uses the technology that seal end, reduced effectively get together the annulus in sulphone colophony 2 get together body matter content, increased polymer quality stability, can control opposite element quality effectively to reach its to distributing; at the same time, the multistage that uses own research and development presses buy of roller cold press fitting, make product extract craft simple and efficient environmental protection, reduced manufacturing cost considerably. This project already applied for to invent 9, among them 5 obtain authorization.
