What are the precautions for producing FRP resin? Do you know? Today, let’s take a look! The spraying quality of FRP resin gel coat directly affects the appearance quality, weather resistance, water resistance, and chemical media corrosion resistance of the product, so it is necessary to Strictly control the application of gel coat.Things to note are as follows: 1. When configuring the fiberglass resin gel coat, mix it thoroughly, especially when using different pigment pastes. If the mixing and distribution are uneven, some spots and streaks will appear on the surface of the product, which will not only affect the appearance of the product but also reduce its quality. Physical properties: Stir evenly when adding the curing agent to avoid surface wrinkles, cracks and other defects caused by uneven curing.2. You can use a brush or a special spray gun to spray glue.If the viscosity of the gel coat is too high, an appropriate amount of styrene can be added to adjust the viscosity and make up for the styrene lost by volatilization during the operation, but the amount of styrene added must be controlled according to process requirements.3. The thickness of the fiberglass resin gel coat layer is controlled at 0.3~0.5mm

The quality of the epoxy vinyl FRP resin base material construction directly affects the bonding force between the FRP structural layer and the steel matrix.If the primer construction is sloppy, it will easily affect the coating's bonding force, cause bubbles, and may even cause the entire layer of FRP to peel off.For base repair, on the basis of laying a good foundation, repair and fill the unevenly dented vinyl fiberglass fiber reinforced plastic resin (resin plus an appropriate amount of quartz powder). Use glue to enter the arc transition at the corners. If the dent is too deep, repair and fill it multiple times to provide Prevent it from flowing, wait until it solidifies, and then flatten it with sandpaper to keep the glue surface flat.Resin glue (resin strengthener mixed with a ratio of 100/4 and then added: quartz powder - 100 250) is applied thinly to prevent hanging, 3-5 kg ​​of each component.Apply glass cloth.After the vinyl FRP resin mortar repair is completely cured and dried for 24 hours, apply a layer of resin to
