近几年来,透明粉末喷涂已经取得了很大的进展。过去,透明度、平整性和总体外观都及不上清漆面层。现在,在平的表面上,平整性虽尚有不及,但是,与任何类似的涂装相比,已能喷出良好的透明面层而不落人后。就大部分零件来说,即使是表面稍弯曲的零件,透明粉末涂层已可与任何透明漆比美。在几乎任何其他方面的比较中,事实证明,粉末涂层的性能相同,甚至更好。本文以黄铜、镀黄铜铸件或青铜物上喷涂透明粉末涂料并按BHMA标准与工业认可的测试方法测试的情况为例,探讨透明粉末喷涂的现状。
In recent years, transparent powder coating has made great progress. In the past, transparency, smoothness and overall appearance were not as good as the finish. Nowadays, on flat surfaces, even though flatness is not matched, it is possible to give a good clear finish over any similar paint without falling behind. For the most part, the clear powder coating is comparable to any clear lacquer even for slightly curved surfaces. In almost any other comparison, it turns out that the performance of the powder coating is the same, even better. In this paper, brass, brass castings or bronze sprayed on the transparent powder coating and BHMA standards and industry-accepted test methods to test the case as an example to explore the status of transparent powder coating.
