养殖网箱、定置网及渔船的船底,一旦附着了藤壶等海洋生物,就会阻碍海水流动,使网具变形、渔船航行阻力增大等问题。以往,为解决此类问题一直使用有机锡合化物作为有机成分的防污剂,由于有毒性不安全,现已被禁止使用。现在普遍使用非有机锡类的替代防污剂,由于这种替代防污剂防止附着效果持续时间短,需要反复涂刷,故造成投入劳动力的大幅度增加,费用加大。为了从根本上解决附着生物的问题,有必要开发不用化学物质的防附着技术。因此,最近开发了利用微电流防止海洋生物附着的新技术。 Aquaculture cages, fishing nets and the bottom of the boat, once attached to marine life such as barnacles, it will hinder the flow of water, so that the deformation of the network, fishing vessels to increase the resistance and other issues. In the past, organotin compounds have been used as an organic component antifouling agent to solve such problems and have been banned because of their toxicity. Nowadays, alternative non-organic tin stain-proofing anti-fouling agents are widely used. Since such alternative anti-fouling agents prevent the attachment effect to have a short duration and require repeated brushings, the input labor force is greatly increased and the cost is increased. In order to fundamentally solve the problem of attaching organisms, it is necessary to develop an anti-adhesion technique that does not use chemicals. Therefore, recently, a new technology that uses micro-current to prevent attachment of marine organisms has been developed.
