产品待焊部位的防锈问题,是金属结构施工中急待解决的课题之一。在国内,防锈可焊涂料尚无理想配方,为此我们根据涂料的防锈可焊原理,研制了近七十种配方的涂料,经过筛选后,来用手工电弧焊、埋弧自动焊及CO_2气体保护焊等方法,分别在各种涂料及无涂料试板上进行焊接试验对比,并进行防锈性能试验,最后终于研制成功“F”型防锈可焊性涂料,其可焊性可与无涂料时相比,防锈性能均已二、F型防锈可焊涂料的物理性能 Rust-proof parts of the product to be welded site is one of the urgent issues to be solved in the construction of metal structures. In China, there is no ideal formula for rust-proof solderable paint. Therefore, we have developed nearly 70 kinds of coating materials according to the rust-proof and solderable principle of paint. After screening, we use manual arc welding, submerged arc welding, CO_2 gas shielded welding and other methods, respectively, in a variety of coatings and non-paint test panels on the welding test contrast, and rust-proof performance test, and finally finally developed “F” rust-proof solderable coatings, the weldability Compared with no paint, anti-rust properties have been two, F-type anti-rust coatings can be coated physical properties
