采用合成树脂密闭离心铝热法制备陶瓷内衬钢管中陶瓷层的气孔、裂纹等缺陷,从而获得了具有防腐耐磨双重功能的复合管材。产品可在真空状态下长期使用,内衬层与钢管基体结合强度高,高温下内村层不鼓泡、不褶皱,使用效果好,适用范围广
The synthetic resin closed centrifugal aluminothermic method was used to prepare the pores, cracks and other defects of the ceramic layer in the ceramic lined steel tube, and the composite pipe with dual functions of anti-corrosion and anti-wear was obtained. The product can be used under vacuum for a long time. The inner lining and the steel pipe substrate have high bonding strength. The inner layer does not blister at high temperature, and has no wrinkles. The utility model has the advantages of wide application range
