随着我国社会主义建设事业的飞跃发展,冶金、化工、仪表等工业对防腐蚀材料的需要更为迫切。许多工业厂房的地坪、酸槽、防腐设备等设施都需要有适宜的防腐蚀材料,特别是耐酸防腐蚀材料。目前在许多耐酸防腐蚀工程中,仍然采用不锈钢、铅板等贵重金属材料。为了贯彻勤俭建国方针,以非金属材料代替金属材料,特别是不用和少用 With the rapid development of China’s socialist construction, the need for anti-corrosion materials in industries such as metallurgy, chemical engineering, and instrumentation is even more urgent. Many industrial plant floors, acid tanks, anti-corrosion equipment and other facilities need suitable anti-corrosion materials, especially acid and corrosion-resistant materials. At present, in many acid-proof and anti-corrosion projects, precious metals such as stainless steel and lead plates are still used. In order to carry out the principle of diligence and founding a nation, non-metallic materials are used instead of metal materials, especially for the lack of
