犁、锄、耙、锹、镐等农具,主要部件是用铁制成的。铁与水、泥、空气接触后易氧化生锈,缩短使用寿命。现介绍几种简易的防锈、除锈方法。一、松香汽油液防锈。用松香末50克,加汽油500克,混合后搅至松香全部溶化就成松香汽油液。将此液涂在没有生锈的铁制农具 Plows, hoes, rakes, shovels, picks and other farm tools, the main components are made of iron. Iron and water, mud, air contact easily oxidized rust, shorten the service life. Now introduce several simple rust, rust method. First, rosin gasoline liquid rust. Rosin 50 grams, add 500 grams of gasoline, mix until all the rosin dissolved rosin gasoline solution. Apply this solution to rust-free iron implements
