The invention relates to the technical field of corrosion prevention of granulation towers, in particular to a granulation tower polyurea spraying process. The granulation tower polyurea spraying process comprises the following steps: step 1, treating a concrete substrate; step 2, brushing a seal primer; and step 3, spraying polyurea. The polyurea elastomer is adopted as an anti-corrosion lining of the granulation tower, the anti-corrosion lining has the advantages of being excellent in anti-permeation performance, low in porosity, compact in structure, small in forming residual stress, high in interface bonding strength with a concrete matrix and the like, and the anti-corrosion lining is easy to construct, short in construction period, free of wall hanging in the production process, low in manufacturing cost and long in service life.
本发明涉及造粒塔防腐技术领域，具体的说是一种造粒塔喷涂聚脲工艺。本发明提供了一种造粒塔喷涂聚脲工艺，包括以下步骤：步骤一：混凝土底材处理；步骤二：刷涂封闭底漆；步骤三：聚脲喷涂。本发明采用聚脲弹性体作为造粒塔的防腐衬里，具有优异的抗渗透性能、孔隙率低、结构致密、成型残余应力小、与砼基体的界面粘结强度高等特点，本发明施工简单、工期短、生产过程不挂壁、造价低、使用寿命长。
