The results show that , anodic oxide films treated with atmp and dtpmp can achieve more perfect hydration resistance , especially dtpmp , which has least rising time , 7s . 4 . use of dibasic ammonium phosphate and gluconic acid delta lactone to improve 研究結(jié)果表明:相對于adp , atmp和dtpmp明顯改善了氧化膜的耐水合特性,其中dtpmp的耐水合處理效果最好,其升壓時(shí)間為7s 。
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(fù)合物的熱穩(wěn)定效果,結(jié)果表明納米鉛鹽能明顯地提高熱穩(wěn)定性,在保證pvc熱穩(wěn)定性的同時(shí)可較普通鉛鹽減少用量25 ? 33 ,同時(shí)討論了添加劑在加入時(shí)應(yīng)注意的問題。
