辣素防污涂料在海洋网箱网衣材料中的应用

The preliminary studies on nontoxic capsaicin antifouling paint

以辣素作为海洋附着生物防污剂,研究了3种辣素防污涂料对海水养殖网衣材料的防污效果.试验于2003年4～10月进行,分别将网片涂上辣素防污涂料(5#)、辣素-聚四氟乙烯(PTFE)(4#)、辣素-硅酸盐防污涂料(8#),对照组网片无涂料(9#),吊挂在试验海区的生产网箱之间,网片吊挂深度为2～3 m,间距为1.5 m左右.试验中,每月吊挂一块新的无涂料网片,用于调查不同季节附着生物的种类和附着情况;每月测量1次海水的温度及透明度,并对网衣进行拍照、称重,计算被污损生物附着的网片占总面积的百分比.结果表明,涂有3种辣素防污涂料的网衣增重比无涂料的对照网衣的增重要小得多,说明防污涂料的防污效果都比较好,尤其是辣素-硅酸盐防污涂料(8#)的防污效果最佳.

Antifouling paints containing capsaicin were hung up between net cages in the test maritime space of Zhoushan in Zhejiang province on April of 2003. The antifouling materials was placed 2 -3 meters below the sea level at an interval of about 1.5 meters. The antifouling materials were checked on the degree of adhesion, weighed and taken pictures once a month. The results showed that the capsaicin antifouling paint has made the satisfactory antifouling effect.
