据悉,我国高速公路通车里程居世界第二,但主要采用普通沥青路面,易损坏、反油,冬天易开裂,寿命短,经常需要维修,严重制约我国高速公路的发展。被国家科技部认定为国家新材料产业化基地的宁波大成新材料公司科技人员经过艰苦探索,研制成功一种高性能路用聚酯纤维。把这种像
It is reported that the mileage of our country’s expressways is the second in the world, but the common asphalt pavement is mainly used, which is easily damaged and oil-repellent. It is easy to crack in winter and has short service life. It often needs maintenance and seriously restricts the development of expressways in our country. Science and technology personnel of Ningbo Dacheng New Materials Co., Ltd., identified as National Industrial Base of New Materials Industrialization by the Ministry of Science and Technology, have successfully explored and successfully developed a high-performance polyester resin for road use.
