技术需求：      Si-69是有机硅烷偶联剂中用途最广的橡胶助剂。近5年其年均需求增速超过15%.公司对Si-69生产工艺进行了研究和改进，现以建成了年产5万吨硅烷偶联剂的生产线。且研究开发出具有自主知识产权的硅烷偶联剂生产工艺软件包并获得了1项国家发明专利。本项目的实施，减轻了工人的劳动强度，提高了产品的产量和质量，使公司硅烷偶联剂业务位居行业领军地位，我司含硫硅烷偶联剂国内市场占有率约为50%。
 
      Si-69 silane coupling agent is the most versatile of rubber chemicals. Past five years, average annual demand growth of more than 15%.The company have been studied and improved production process for Si-69, build an annual output of 50,000 tons of silane coupling agent production line. And research and development of a national invention patents having a silane coupling agent production technology with independent intellectual property package and received. Implementation of the project, reducing the labor intensity, improve the yield and quality of the products, the company silane coupling agent business among the industry leadership position, our sulfur-containing silane coupling agent of the domestic market share of about 50%.
