Lead hydrogen phosphite superfine powder , lead oxide phosphite hydrate superfine powder and tribasic lead sulfate superfine powder were prepared by micro - liquid - phase synthesis method ( mlps method ) in this paper . at room temperature , acetic acid worked as catalyst , lead oxide and phosphite or sulfate were blended thoroughly , then were ground for tens minutes 本文采用微液相合成法制備了亞磷酸鉛、二鹽基亞磷酸鉛和三鹽基硫酸鉛超細粉末,以氧化鉛和亞磷酸或硫酸為原料,以醋酸為催化劑,在室溫下充分混合、研磨幾十分鐘,干燥后即可得到產物。

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 利用剛果紅法測試了納米二鹽和三鹽復合物的熱穩定效果,結果表明納米鉛鹽能明顯地提高熱穩定性,在保證pvc熱穩定性的同時可較普通鉛鹽減少用量25 ? 33 ,同時討論了添加劑在加入時應注意的問題。

Application : tribasic lead sulfate is a thermal stabilizer for pvc plastic products with excellent thermal stability and electrical insulation . it is mainly used in manufacturing opaque hard and soft products 用途:本品為聚氯乙稀塑料制品的熱穩定劑。具有優良的熱穩定性和電絕緣性,主要用于不透明的硬質制品及軟質制品。
