专利汇可以提供Method for submarine antistaining专利检索,专利查询,专利分析的服务。并且PURPOSE: To prevent the damage by submarine animals and plants for a long term, by covering submarine and underwater structures with the surface of a polyvinylidene fluoride in a laminated material of the chemically very stable and inert polyvinylidene fluoride free from toxicity of the surface layer.
CONSTITUTION: A laminated material of polyvinylidene fluoride as a surface layer is used in underwater and submarine structures, e.g. ship bottom, tanks or buoys, or fishing nets, e.g. raising nets or fixed shore nets, to prevent the damage by submarine animals and plants. A laminated material, e.g. a laminated film sheet having the polyvinylidene fluoride as the surface layer and plastic, metal or wood having the polyvinylidene fluoride as the surface material are used as the laminated composite material. The thickness of the polyvinylidene fluoride is usually within 5μmW10mm, preferably 10μmW1mm, range. An antistaining agent, e.g. a triphenyltin compound, may be incorporated in the polyvinylidene fluoride layer.
