Abstract
The invention relates to the use of mineral fibres or filaments and E-glass fibres having a SiO2 part of more than 50 wt. % in the form of a textile fabric, as a biocide-free antifouling agent for protecting submerged structures from damage by adhesion and multiplication of aquatic pests in the sea or in industrial water systems. The surface of the antifouling agent predominantly consists of fine basalt fibres and the fabric is woven, knitted or braided, a fabric formed according to multiaxial technology, or a nonwoven.
Claims14
A method of reducing or delaying damage to submerged structures due to adhesion and multiplication by harmful organisms living in the water in seawater or in industrial water systems, comprising the step of applying to the outside of the structure a biocide-free antifouling agent comprising fine basalt fibers or filaments, or comprising a combination of fine basalt fibers or filaments and E glass fibers, wherein the fine basalt fibers or filaments or E-glass fibers have a SiO2 rate of more than 50% by weight,
- wherein the antifouling agent is applied in the form of a textile fabric selected from the group consisting of interlaid scrim, woven fabric, knitted fabrics or braiding, a fabric designed by the multiaxial technique, and a fleece,
- wherein the exterior surface of the textile fabric to be in contact with the seawater or industrial water is formed predominantly by exposed free fine basalt fibers or filaments.
