Shanghai Daoqin Plastics Co., Ltd.

         for/regarding plastics alloy 预处理, most commonly used methods is add plastics agent MK800, its use features and use 说明如 lower:

        (一) features

         main applications 于PC材 material or PC content relatively high ABS mixed combined plastics, function is make plastics surface rear, rear coarse chemical industry more add has 效, ensure good plating combined force.

        (二) equipment

        (三) as parameters

         temperature degree: 20 – 70 °C

         time: 3 – 6 separation 钟

        (四)镀 liquid made

         acid alkali liquid 由60 克/ rise acid hydrogen 钠(NaH2PO4·H2O) add 72 克/ rise acid hydrogen 二钠(Na2HPO4)配 made formed.

        (五)配 made steps

        1, in inner 注入 需 pure water.

        2, in lower add plastics agent and already made pH acid alkali liquid.

        3, add pure water 至 需 容 amount, uniform rear can use.

        (六) analysis methods

        试 agent —— chlorine 化钠

         steps:

        1, temperature degree drop room temperature 100 milli rise solvent liquid has degree amount in.

        2, add 10克 chlorine 化钠, uniform, let solvent liquid delamination.

        3, upper solvent liquid 体积.

         plastics agent content (milli rise / rise) = upper solvent liquid x 10

        (七) attention/notes 事項

        1, rise plastics agent as liquid in 处理2平方米面积 rear, as formed analysis and 补充.

        2, solvent liquid 需 膨胀 agent concentrated degree 视处理 plastics in PC content 而定.

        3, plastics agent usually used for acid -硫 acid coarse front 工序.

        4, 补充时 application pure water as add.

        (八) waste water 处理

         waste liquid inner a large amount of has machine material, strong/high oxidation agent or high temperature 销毁. water can alkali rear (pH 8.5 – 9.5)排放至 acid alkali 处理槽处理.
