由中国石油天然气总公司科技发展部、基建工程部联合主持召开的“次超轻憎水硅酸钙保温材料”鉴定会于1990年12月6～7日在石家庄市召开。来自有关油田、大专院校及研究单位的保温技术专家对该项目作了认真的实事求是的评价,给予充分肯定并一致同意通过鉴定。微孔硅酸钙保温材料以其优良的保温性能在国内外得到愈来愈广泛的应用。石油工程技术研究所针对该材料的发展方向,结合国情作了重要的改进;一是研制成功S·H·-G化学外加剂,通过简易的活化处理,提高了硅钙
The “Secondary Ultra-light Hydrophobic Calcium Silicate Insulation Materials” appraisal meeting jointly organized by China National Petroleum Corporation’s Ministry of Science and Technology and the Ministry of Infrastructure Engineering was held in Shijiazhuang City from December 6 to 7, 1990. Thermal insulation experts from relevant oilfields, universities and research institutes made serious and realistic comments on the project, fully affirmed and agreed to pass the appraisal. Microporous calcium silicate insulation has been widely used at home and abroad for its excellent thermal insulation properties. The Institute of Petroleum Engineering and Technology has made important improvements in light of the development direction of the material and in light of the national conditions. The first is the successful S·H·-G chemical admixture, which has been enhanced by a simple activation process.
