摘要：
The present invention involves a method of removing paint containing heavy metal from a surface without the production of hazardous wastes. Specifically, this method involves applying a coating preparation to the heavy metal containing paint prior to its removal from its surface. The preparation contains lead reactive chemicals such as phosphates, metal sulfides and organic sulfides. The preparation may also contain buffers such as magnesium oxide and magnesium hydroxide. These chemicals react with the heavy metals rendering them nonhazardous. The invention also involves the coating preparation itself.
摘要（中）：
本发明涉及从表面除去含有重金属的涂料而不产生危险废物的方法。 具体地说，该方法包括在其重金属的涂料从其表面除去之前涂覆涂料制剂。 该制剂含有铅反应性化学物质，如磷酸盐，金属硫化物和有机硫化物。 该制剂还可以含有缓冲剂如氧化镁和氢氧化镁。 这些化学物质与重金属反应使其变得无危险。 本发明还涉及涂层制剂本身。
