Described water soluble surfactant active, catalyzer and organic mass ratio are 1 ﹕, 5～20 ﹕ 3～10;
2). with tile to the equably surface of the immersed solder pot that contains the part tin alloy solder of tin ash, the solution of selecting that will be made into again is poured into the tin ash surface equably, slowly is warming up to 80 ℃～110 ℃, evaporative removal moisture slowly, until moisture by evaporate to dryness;
Described mass ratio of selecting solution and tin ash is 1 : 10～30;
The described immersed solder pot that contains the part tin alloy solder, containing the part tin alloy solder mainly is in order to protect immersed solder pot heating tube;
Further be that described immersed solder pot also can substitute with other heating containers that meet the demands;
3). slowly be warming up to 230～300 ℃ of the melt temperatures of tin alloy solder, insulation reaction 2～5h until not having water and carbon dioxide generating, scrapes off the impurity such as black carbide on surface with scraper plate gently, and its main chemical reactions is:
X in the molecular formula of described phosphoric acid and ammonium salt thereof or organic amine salt mixture (XI) is selected from ammonium ion or the organic amine ion one or more, the Y in its resultant of reaction polyphosphoric acid (salt) structural formula (XII)
