酸洗

The result indicated: Although pressure through membrane of UF system has get some recovery (from 0.022MPa to 0.089MPa). The effect of sodium hyposulfite cleaning is not good.

结果表明：由膜污染引起的膜压差得到一定程度的恢复（由0.16MPa降到0.075MPa），酸洗效果较好，次氯酸钠清洗效果较差。

Because of this technology does not need the process of acid pickling and high temperature, there is no hydrogen embrittlement took place in the spare parts, and it possess a great deal of merits such as self-healing function after scotch, meanwhile it has hyper heat-resistance, hyper tonicity, hyper stickability, hyper anti-friction, hyper weatherability, hyper corrosion resistance, and when used outside, it can maintain its color for a long-period without change.

由于该工艺不经过酸洗和高温，所以零件无氢脆发生，擦碰伤后还有自愈合功能，同时还具有高耐热性，高渗透性，高附着性，高减摩性，高耐候性，高耐化学品腐蚀性。用在室外可长期保持不变色等诸多优点。
