Description
(1) technical field
The present invention relates to a kind of low surface energy organic silicon paint and uses thereof.
(2) background technology
Fishery fish for underwater operations such as aquaculture in, the operation of mobile netting gear in water is all arranged.Be immersed in netting gear in the water and in water, when mobile, overcome the resistance of water, need the external force acting.
Netting gear can reduce the adsorptive power of water to the netting gear fibril after applying low surface energy coatings, thereby reduces netting gear running resistance in water.Use low water drag power netting gear and fish for, can save the energy consumption that drags fishing boat, improve ship's speed, reduce labor intensity and increase catch.Use the netting gear fibril hydrophobicity raising that low surface energy coatings applies, can stop the apposition growth of aquatic organism on netting gear, also help netting gear and prevent going mouldy, thereby prolong the work-ing life of netting gear.
Use low surface energy coatings and reduce the netting gear water resistance, do not related to as yet in the prior art.
