The solution for FRP panels mainly includes preparation before construction, construction technology, and precautions during the construction process.
Preparation before construction involves design preparation, preparation of materials, preparation of tools and grassroots treatment. Design preparation includes determining the thickness, shape and size of the FRP facing according to engineering requirements, and providing complete drawings and technical requirements. Material preparation includes selecting glass fiber cloth, resin, curing agent, fillers and other materials that meet the requirements, and checking the quality certificates and inspection reports of the materials. Tool preparation includes preparing construction tools such as mixers, brushes, scrapers, and rollers, as well as necessary supporting equipment such as scaffolds and platforms. Base treatment includes cleaning the surface of the base to ensure that it is free of oil, dust and other impurities, and carrying out necessary repairs and reinforcement of the base.
The construction process includes resin blending, primary coating, glass fiber cloth pasting, top coating, curing and quality inspection. Resin preparation is to mix the resin and curing agent in proportion according to the requirements of the instructions, and add appropriate amount of filler. Brushing primer is to apply a layer of primer on the surface of the substrate to increase the adhesion between the glass fiber cloth and the substrate. The glass fiber cloth is pasted on the surface of the base layer according to design requirements to ensure smoothness and no bubbles. Brush surface coating is to apply one layer of coating on the surface of glass fiber cloth to protect glass fiber cloth and enhance waterproof performance. Curing and quality inspection include natural curing at room temperature or heating curing as required, and quality inspection of the cured FRP surface layer, including appearance inspection,
During the construction process, attention should be paid to selecting appropriate weather and environmental conditions to avoid construction in rainy days, windy days and high temperatures. Necessary protective measures should be taken, such as wearing gloves, masks, glasses, etc., to protect the safety and health of construction personnel. Used waste and residual materials should be properly disposed of to avoid pollution to the environment. Comply with relevant safety operating procedures and laws and regulations to ensure construction safety and quality. During use,
