Fiberglass (referred to as glass fiber) refers to an inorganic non-metallic material made of pyrophyllite and kaolin as raw materials through high-temperature melting, drawing, drying, winding and reprocessing of raw yarn. Glass fiber is a new type of material with superior performance, and it is also a new material that our country encourages to develop. In recent years, with the continuous favorable national policies and the improvement of enterprise research and development capabilities, the scale of the fiber glass industry has gradually expanded.

"Waste-free city" is guided by the new development concept of innovation, coordination, green, openness and sharing. By promoting the formation of green development methods and lifestyles, it will continue to promote the reduction and resource utilization of solid waste sources, and minimize landfilling. An urban development model that minimizes the environmental impact of solid waste.

Chopped glass fiber is also called glass fiber chopped strand. Quartz sand is melted at high temperature, and the fiberglass raw filaments drawn with special sizing agent (softening agent) are chopped online by wet method, or the product glass fiber is chopped.It has functions that other glass fiber

The advancement of engineering materials is the driving force behind the development of engineering structures. The history of bridge construction for thousands of years is also a history of bridge construction materials. The invention and promotion of new materials often greatly promote the development of bridge engineering. Historically, concrete and steel are good examples. Since the 20th century, these two "new" materials have gradually replaced ancient bridge construction materials such as wood, stone, and brick in the world, enabling human bridge construction to achieve unprecedented great development.

Architects, engineers and builders are increasingly using fiberglass pultrusion for a variety of construction and infrastructure projects, and this trend is accelerating due to the many benefits the technology offers. Pultrusion is a process for producing linear fiber reinforced plastic (FRP) composite profiles with a uniform cross-section. Pultrusion machines strengthen fibers by dipping them in a resin bath, then pulling them through a heated die, where they cure.

1. Price The recent stabilization and recovery of prices mainly relies on large enterprises taking the lead in active cold repairs and suspending projects under construction and proposed construction. The thinking has changed, hoping to stabilize prices and the market (different from the last round
