化学除油

介绍了高速公路护栏杆和锥形电杆用涂塑钢管的优点及涂塑工艺。提出：涂覆前的预处理先进行化学除油，再进行酸洗去锈，最后进行磷化处理；

This paper introduces the coated plastic steel pipe advantage and its process for expressway railing column and conical lighting poles , and puts forward the coating steps before pre-coating , that is : chemical degreasing for pre-processing ;

本课题中，主要研究重油原料的化学除油剂和除油工艺，期望使用适当的表面活性剂复配在低的pH值和常规工艺条件下就能达到良好的除油效果。

In this dissertation , the focus will be put on the chemical oil-removing agent and process for heavy oil materials and good effects are hoped to reach at low pH value and ordinary technical conditions through the mixture of surfactants .

实验表明：化学除油的温度和时间对镀层结合力的影响很大，而酸洗除锈液中缓蚀剂的含量对镀层结合力的影响不大。

The temperature of olkaline solution and degreasing time were found influencing the adhesion obviously but the amount of restrainer in derusting solution had little effect on adhesion .

试验筛选了合理的化学除油、弱酸浸蚀和碱性预化学镀的工艺，分析锌基合金化学镀镍的机理，通过酸性化学镀镍溶液的成分对镀镍速度的影响进行镀液优化。

The desirable alkaline degreasing , mild acid etching and alkalic electroless nickel preplating process are experimentally chosen . The mechanism of electroless nickel deposition on zinc-based alloy is discussed . The plating bath is optimized by investigating the influence of ingredients on deposition (?)
