When building and maintaining swimming pools, it is crucial to choose the right material. Fiberglass is an ideal choice in swimming pool construction because of its excellent mechanical properties, corrosion resistance and waterproofness. This article will explore the application of different types of fiberglass (fiberglass spray up roving, chopped strand mat, woven fabric) in swimming pools and their advantages and disadvantages to help you make a wise choice.
Fiberglass can significantly improve the structural strength and durability of swimming pools, ensuring that they remain stable in long-term use.
Fiberglass has excellent waterproof performance, which can effectively prevent water penetration and extend the service life of swimming pools.
Fiberglass can resist the corrosion of chemicals (such as chlorine), ensuring that swimming pools will not be damaged by corrosion during use.
o Definition and characteristics: Fiberglass spray up roving is a composite material made of glass fiber and resin through a specific process. It is mainly used in the injection molding process, and the fiber and resin mixture is sprayed onto the mold surface through a high-pressure spray gun to form the desired composite product.
o Manufacturing process: The manufacturing process of fiberglass spray up roving includes steps such as fiber preparation, impregnation, molding and curing. After the fiber is melted, drawn and cooled, it is mixed with resin, then sprayed onto the mold surface by a high-pressure spray gun, and finally cured by heating.
o Performance characteristics:
▪ High strength: Fiberglass spray up roving has the characteristics of high strength and light weight, and is suitable for application scenarios that need to withstand large external forces.
▪ Corrosion resistance: Fiberglass spray up roving has good tolerance to chemicals such as acids, alkalis, and salts, and is suitable for corrosive environments.
▪ High temperature resistance: Fiberglass spray up roving can still maintain stable performance under high temperature environment, and is suitable for high temperature working environment.
o Definition and characteristics: Chopped strand mat is a composite material made of chopped glass fiber and resin. It is usually used in hand lay-up molding process, where the chopped strand mat is manually laid on the mold and then coated with resin.
o Manufacturing process: The manufacturing process of chopped strand mat includes steps such as fiber cutting, dispersion, impregnation and drying. After the chopped fibers are evenly dispersed, they are mixed with resin and then made into chopped strand mat through a drying process.
oPerformance characteristics:
▪ Softness: Chopped strand mat has good softness, is easy to lay and shape, and is suitable for molds with complex shapes.
▪ Corrosion resistance: Chopped strand mat also has good corrosion resistance and is suitable for various corrosive environments.
▪ Cost-effectiveness: Chopped strand mat has a relatively low cost and is suitable for large-scale production.
oDefinition and characteristics: Fiberglass woven roving is a composite material woven from continuous glass fibers. It is usually used in lamination processes by laying the Fiberglass woven roving on the mold and then applying resin for curing.
oManufacturing process: The manufacturing process of fiberglass woven roving includes steps such as fiber weaving, impregnation and drying. Continuous glass fibers are woven into Fiberglass woven roving by a weaving machine, then mixed with resin and made into Fiberglass woven roving through a drying process.
oPerformance characteristics:
▪High strength: Fiberglass woven roving has high strength and rigidity and is suitable for application scenarios requiring high structural strength.
▪Dimensional stability: Fiberglass woven roving has good dimensional stability and is not easy to deform, and is suitable for molds requiring high precision.
▪Corrosion resistance: Fiberglass woven roving also has good corrosion resistance and is suitable for various corrosive environments.
o Pool walls and pool bottoms: Fiberglass spray up roving is often used for the pool walls and pool bottoms of swimming pools, providing high strength and corrosion resistance. Through the spray molding process, the construction can be completed quickly and efficiently, ensuring the structural strength and waterproof performance of the swimming pool.
o Surface treatment: Fiberglass spray up roving can also be used for the surface treatment of swimming pools, providing a smooth and durable surface that is easy to clean and maintain.
o Pool walls and pool bottoms: Chopped strand mat is often used for the pool walls and pool bottoms of swimming pools, providing good softness and corrosion resistance. Through the hand lay-up molding process, it can flexibly adapt to various complex mold shapes to ensure the structural strength and waterproof performance of the swimming pool.
o Surface treatment: Chopped strand mat can also be used for the surface treatment of swimming pools, providing a smooth and durable surface that is easy to clean and maintain.
o Pool walls and pool bottoms: gingham cloth is often used for the pool walls and pool bottoms of swimming pools, providing high strength and dimensional stability. Through the lamination molding process, the structural strength and waterproof performance of the swimming pool can be ensured.
o Surface treatment: Fiberglass woven roving can also be used for the surface treatment of swimming pools, providing a smooth and durable surface that is easy to clean and maintain.
o Strength: fiberglass spray up roving and fiberglass woven roving have higher strength and are suitable for application scenarios that require higher structural strength; chopped strand mat has relatively lower strength but better softness.
o Corrosion resistance: All three types of glass fibers have good corrosion resistance and are suitable for various corrosive environments.
o Construction convenience: Fiberglass spray up roving uses a spray molding process, with fast construction speed and high efficiency; chopped strand mat uses a hand-layup molding process, which is suitable for molds with complex shapes; fiberglass woven roving uses a lamination molding process, which is suitable for high-precision molds.
o fiberglass spray up roving: moderate cost, suitable for mid-to-high-end markets.
o Chopped strand mat: low cost, suitable for large-scale production and economical markets.
o Fiberglass woven roving: high cost, suitable for high-end markets and application scenarios with high precision requirements.
o fiberglass spray up roving: fast construction speed, suitable for large projects.
o Chopped strand mat: flexible construction, suitable for molds with complex shapes.
o Grid cloth: high construction accuracy, suitable for high-precision molds.
o Large swimming pool: It is recommended to choose Fiberglass spray up roving or gingham cloth to ensure structural strength and waterproof performance.
o Small swimming pool: Chopped strand mat can be selected to reduce costs and meet basic needs.
o Outdoor swimming pool: It is recommended to choose fiberglass spray up roving or gingham cloth to improve weather resistance and corrosion resistance.
o Indoor swimming pool: Chopped strand mat can be selected to reduce costs and meet basic needs.
