Congo - red method was used to determine the thermal stabilization ability of products , which were consisted of dibasic lead phosphite and tribasic lead sulfate . the results showed that the nanometer stabilizer obviously increased the ability of thermal stabilization . in the same thermal stability level it could cut 25 % - 33 % amount of lead salt than using ordinary products 利用刚果红法测试了纳米二盐和三盐复合物的热稳定效果，结果表明纳米铅盐能明显地提高热稳定性，在保证pvc热稳定性的同时可较普通铅盐减少用量25 ? 33 ，同时讨论了添加剂在加入时应注意的问题。
