比起铅来,金属锡的电正性没有二氧化锡的电负性强,所以无法产生可用的电位差。
Metallic tin is not electropositive enough compared with the electronegativity of its oxide to deliver a useful potential difference.
结果表明,该添加剂工艺稳定性好,且镀层可焊性优良、抗变色能力强,可取代高污染的锡铅电镀工艺。
The result proves that the process has advantages of high stabilization, excellent solderability and antitarnishing, which may replace high-pollution tin-lead electroplating technology.
硫化体系采用酚酸树脂2402/氯化亚锡(8/0.5)、加入一定量的增塑剂邻苯二甲酸二辛酯和补强剂高耐磨炭黑,可获得性能较好的共混体。
A blend with better properties could be obtained by adding phenolic resin 2402/tin bichloride (8/0. 5) curative and a certain level of dioctyl phthalate plasticizer and HAF reinforcing agent.
