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。
The anti-fouling effect of three kinds of anti-fouling anti-fouling paints on the marine culture netting materials was studied by using the marine anti-fouling agent as the marine anti-fouling agent. The experiment was conducted from April to October in 2003. The mesh was smeared with antimicrobial (# 5), spicy - polytetrafluoroethylene (PTFE) # 4, (8 #). The control group had no coating on the mesh (9 #) and hung between production cages in the test sea area. The mesh hanging depth was 2 ~ 3 m and the spacing was about 1.5 m. In the experiment, a new uncoated mesh was hung every month to investigate the species and attachment of attached organisms in different seasons. The temperature and transparency of the seawater were measured once a month, and the mesh was photographed, weighed and calculated The percentage of the total area covered by the fouling organisms. The results show that coated with three anti-fouling anti-fouling coating weight gain than the non-coated control clothing weight is much smaller, antifouling paint antifouling effect is better, especially the spicy - silicic acid Salt anti-fouling paint (8 #) the best anti-fouling effect.
