【无机富锌漆】研制及其在重防腐领域的应用
       无机富锌漆在金属构造物防腐上的应用,主要有水性环氧富锌底漆和无机富锌漆。在金属构造物防腐蚀涂装体系中,富锌底漆的作用特别重要,它对钢铁结构具有良好的附着力,并能起到优异的抗腐蚀作用。本文主要从组成成分、性能、应用领域、配套等方面来比较水性环氧富锌底漆和无机富锌漆的区别。
       一、成分区别。
       无机富锌漆是以无机硅酸盐为基料、锌粉为主要防锈颜料,添加多种填料和助剂而组成的重防腐涂料;Waterborne epoxy zinc rich primer is a two component coating. Water is used as diluent. Zinc powder, waterborne epoxy emulsion, filler, pigment and polyamide aqueous dispersion curing agent are used.
       二、应用区别。
       无机富锌漆可应用于油罐、油舱、溶剂舱、压载水舱及环境和条件苛刻的海洋钢铁结构,桥梁、烟囱等,以及作为防锈耐热涂料使用。其施工简单方便,漆膜干燥迅速,硬度高,防护性能优异。In terms of film properties, inorganic zinc rich coating has high hardness and brittleness, so it is not suitable for thin-walled metal structures. It is very suitable for large-scale metal structures and iron castings with high anti-corrosion requirements. When it is used together with high-performance intermediate paint and topcoat, the anti-corrosion performance can be further improved.
       水性环氧富锌底漆做为底漆适用于轻度至防腐要求比较高的工程项目涂装,如钢构、桥梁、船舶、集装箱、海上平台、码头等海洋设施、石油化工管道与储罐、冶金、电力等行业的钢铁防腐防锈。
       三、配套性区别。
       无机富锌漆除不能和油性漆配套外,均能与丙烯酸聚氨酯、环氧漆、乙烯漆等配套。The surface layer of inorganic zinc rich primer is porous material, the internal structure will remain the atmosphere, and it is easy to appear bubbles when coating other architectural coatings. In order to completely solve the problem of foaming, a sealing paint is usually applied.
