刘俊杰报道近日,中轻特材公司申请的河北省科技小巨人项目“全热空气换热器用高阻隔性隔离纸”通过河北省科技厅批准立项。本项目研发产品是一种高性能纤维材料,纸页薄,气密性好,透湿度高,产品热交换效率高(焓效率≥70%)。纸页结构非常致密,能够有效地阻隔新旧空气的对流。另外,纸张通过特殊的表面处理, Recently, the application of light specialties in Hebei Province small technology giant project “all hot air heat exchanger with high barrier isolation paper ” approved by the Hebei Provincial Science and Technology project. The research and development product of this project is a kind of high-performance fiber material with thin paper, good air tightness, high moisture permeability and high heat exchange efficiency (enthalpy efficiency≥70%). Paper structure is very dense, can effectively block the convection of old and new air. In addition, the paper through a special surface treatment,
