Abstract

The invention discloses a wind power blade mold surface cleaning solvent and application thereof. The wind power blade mold surface cleaning solvent is prepared from the following raw materials in parts by weight: 1 to 3 parts of propane, 6 to 10 parts of isobutane, 4 to 6 parts of n-butane, 6 to 10 parts of nonane, 4 to 6 parts of petroleum extract, 1 to 3 parts of n-heptane, 0.1 to 0.3 part of oleic diethanolamide, 8 to 12 parts of n-nonanol and 6 to 10 parts of isovaleraldehyde.

Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine blade processing, and in particular to a wind turbine blade mold surface cleaning solvent and application thereof. Background Art

[0002] Wind turbine blade mold processing refers to the manufacture of molds used to produce wind turbine blades. Wind turbine blade molds are made of fiberglass. As the blade is manufactured, glue spraying, resin residue, etc. make the blade surface roughness increasingly higher. There is a risk of adhesion damage during blade demolding, and the bonding area is poorly coupled, making it impossible for NDT to perform effective inspections, which can easily lead to missed defects. Production must be stopped immediately for mold maintenance and cleaning.

[0003] The existing mold maintenance is done by the production team using an air grinder to polish the mold surface with 80-600 mesh sandpaper according to the mold surface roughness. A single set of molds requires a team of 35 people to maintain for more than one day, and a lot of materials such as sandpaper and air pipes are consumed, while dust is generated to pollute the environment.

[0004] In view of this, the present invention is proposed. Summary of the Invention

The present invention sprays or wipes the surface of the wind turbine blade mold with the surface cleaning solvent, and the surface cleaning solvent can react with the spray resin residue on the surface of the wind turbine blade mold, thereby decomposing the glue stains into substances that are soluble in water or easier to fall off from the mold. Combined with manual wiping, the smoothness of the wind turbine blade mold surface is restored.
