铸铁件在机械加工后,加工面裸露在空气中极易生锈。为此,我们几经摸索,配制成了铸件用防锈剂,使用效果较好。 1.材料选择及配比 (1) 机械油它在防锈剂中起溶剂和成膜剂作用,选用5号油。 (2) 石蜡在防锈剂中做成膜剂,选用54°石蜡。 (3) 石油磺酸钡(烷基碘酸钡) 在防锈剂中起缓蚀防锈作用。 (4) 环烷酸锌作用同烷基磺酸钡。 (5) 对苯二酚作为抗氧剂,防止石蜡和油的酸败,同时也起着缓蚀作用。
Cast iron parts in the machining, the processing side exposed in the air easily rusty. To this end, we tried to find out, formulated into a rust-proof castings, the use of better. 1 material selection and ratio (1) mechanical oil It acts as a solvent and film-forming agent in the rust inhibitor, the choice of No. 5 oil. (2) paraffin wax in the rust-making agent, the choice of 54 ° paraffin. (3) Barium petroleum sulfonate (barium alkyl iodate) acts as a corrosion inhibitor in the rust inhibitor. (4) Zinc naphthenate with barium alkyl sulfonate. (5) hydroquinone as an antioxidant to prevent the rancidity of paraffin and oil, but also plays a role in corrosion inhibition.
