A huge safety hazard, melting falling ice can be enough to kill or seriously injure people, and can also cause property damage. For example, when the bridge cables melted, they repeatedly injured pedestrians and damaged vehicles.
This problem is actually very simple to solve, it involves using the wind turbine blades solution to melt the ice. Apply super-hydrophobic coating to cables and bridge towers, and water droplets will appear like lotus leaves on the cables, which can slow down freezing and quickly melt ice, effectively solving these problems.

How to deal with FRP spray paint?
1. Surface treatment of FRP products before painting:
1. Wax removal: In order to facilitate the demoulding of FRP products during processing, a layer of non-stick wax will be applied to the mold, so there will be a layer of wax on the surface of the product. If it is not removed cleanly, it will affect the sealing force of the paint, causing paint peeling, oil stains and the like. defects;
2. Wax removal method: use a pneumatic grinder and a P180 gauze sheet to carefully grind the surface of the product, and then check whether it is clean until the gloss The surface of the product disappears. Use a pneumatic grinder in areas that cannot be polished by the grinder. When polishing by hand, do not miss anything, otherwise serious quality problems will occur.
3. Grinding processing: When spraying FRP products, you must have a good flat surface first. If heThis is a wide and thick material, you must use an electric angle. grinder and an emery cloth wheel. Rough sanding. If the surface of the mold is relatively smooth after it comes out, you should use a powerful pneumatic grinder to grind it with coarse sandpaper, and then fill the defective areas with putty (. The putty can fill the uneven surface of the fiber material At the same time, the putty can improve the adhesion of the paint surface and the paint will not fall off after painting. To polish the putty, use a medium pneumatic grinder with 120-320 grit sandpaper. After grinding, fill with putty (red gray) if necessary to repair the putty layer, then grind with a fine pneumatic grinder with 400-600 grit sandpaper after grinding. For primer, sand it carefully. with a fine grinder and 400-600 grit sandpaper. Spray the finish coat againwe. If the requirements for a smooth paint surface are not particularly high, you can omit the process of filling putty and primer and spray the top coat directly after sanding the putty.
Of course, factories can also use dust collection and grinding systems. The dust collection and grinding system uses a professional electric or pneumatic dust suction sander, combined with an industrial electric dust collector, and is a waterless grinding method. The dust crushed by the sander is directly sucked into the dust collection bucket by the linked system. Dust collection host. There is no dust flying, ensuring a clean working environment and the health of operators. Rejecting respiratory and occupational diseases, through the use of professional tools, the grinding speed is greatly increasedtee, the labor intensity is reduced and the grinding and repair time is shortened, thereby greatly improving work efficiency.
2. Factors for Selection of Painting on FRP:
When painting on FRP, you just need to ensure that the paint is In terms of adhesion and applicability, you can choose a suitable paint set.
Adhesion Guarantee: Choosing a light gray epoxy primer can guarantee adhesion for most coating requirements. The wind power industry can use special fiberglass coatings for wind power.
Regarding the applicability of the paint, depending on the environment in which the FRP components are located, the corresponding resistances to weather, super weather resistant, acid and Alkali resistant and oil resistant varieties of top coats should be selectedctioned.
Depending on the environment in which the fiberglass reinforced plastic components are located, different paint packages can be used:
For ordinary outdoor environments, use them directly. An acrylic urethane top coat will do the trick.
Super weather-resistant exterior coating: epoxy primer + fluorocarbon finish
Interior environment: epoxy primer + polyurethane finish
p>
Interior environment: epoxy primer + polyurethane finish
p>
Humid interior environment, hot and humid environment: epoxy primer + epoxy finish
Acid For corrosive environments, you can choose acrylic polyurethane top coat
For alkaline and corrosive indoor environments, you can choose an epoxy topcoat
3. In short, itThere's no problem. when using paint on the back of FRP products. The prerequisite for using it on a smooth surface is to polish it with sandpaper to remove wax on the surface of the product and also increase the adhesion of the paint. and FRP materials can have strong bonding. Power is a special commodity.

Professionally applied glass paint: Glass can be heated appropriately because the expansion coefficients of glass and glass paint are different. and the layers will separate quickly You can make a slit on the edge and peel off a layer You can also use the above method: strip.ant for paint
But when using paint stripper, be very careful not to come into contact with human skin. In case of contact, rinse immediately with plenty of water.
