| 山东玻璃钢管表面玻璃膜的去除方法是什么 What is the method of removing the Shandong surface glass steel membrane 由于山东玻璃钢管挤压时采用了玻璃润滑剂，挤压钢管内外表面上残留一层厚度20～50μm的玻璃膜，其性质硬而脆，有害于以后的加工和使用，必须清除。清除方法有机械法和化学法。 Because of Shandong glass pipe extrusion using glass tube extrusion lubricant, internalexternal surface residual layer thickness of 20 ~ 50 μ m glass membrane, the properties of hardbrittle, harmful processinguse in the future, must be removed. Clear method of mechanical methodchemical method. 由于在山东玻璃钢管表面上残留的玻璃润滑剂具有较高的化学稳定性，清除它需要采用碱溶液或酸溶液。酸洗法的不足之处在于对各种钢管材质的侵蚀性大，可能使山东玻璃钢管表面产生过酸洗，尤其对碳钢的侵蚀性更大，因此应用上受到限制。在众多企业中大都采用酸碱联合的清除法。 Because with the higher chemical stability in the glass lubricant Shandong glass steel pipe surface residue, removing it requires the use of alkali solutionacid solution. Deficiencies in the pickling process lies in the erosion of various steel materials, could make Shandong glass steel pipe surface pickling, especially corrosion of carbon steel is bigger, so the application is limited. Many enterprises mostly adopt joint clearance method of acid-base. |
