国内气相缓蚀剂的研制和应用已有二十多年的历史,应用的形式主要是粉剂、气相纸及气相缓蚀片。最近长春气相防锈纸厂试制成气相硅胶,并在试验室内对其缓蚀效果进行了初步试验。气相硅胶是气相缓蚀剂与干燥剂硅胶的复合体,其制做是通过溶剂法将气相缓蚀剂吸收到硅胶的微孔或表面。硅胶具有多孔结构和表面很大的特点,在它表面覆盖着羟基,故亲水性很强,能够吸收包装空间中的潮湿,对钢、硅钢、镀锌钝化等有明显的防锈效果、特别是在对湿度大的环境下更为显著。它的特点:
The development and application of domestic vapor phase corrosion inhibitor has been more than 20 years of history. The main application forms are powder, gas paper and vapor corrosion inhibitor. Recently Changchun vapor phase rust-proof paper mills trial production of vapor silica gel, and in the laboratory for its initial corrosion test results. Vapor phase silica gel vapor phase corrosion inhibitor and desiccant composite of silica gel, which is made by solvent method vapor-phase corrosion inhibitor absorbed into the pores of silica gel or surface. Silica gel has a porous structure and a large surface features, in its surface covered with hydroxyl, it is highly hydrophilic, can absorb moisture in the packaging space, steel, silicon steel, galvanized passivation and other significant anti-rust effect, Especially in the humidity environment is more significant. Its features:
