Analysis of the development process of standardized roads with glass yarn

Fiber Glass polyurethane, which has been frequently questioned in recent years, has also been mentioned again. Polyurethane is a polymer synthetic material with significant performance advantages such as thermal insulation, heat insulation, and sound insulation. It is widely used in the field of building insulation. However, its flame retardancy has serious flaws. Even if flame retardant materials are added, it is still flammable. Most of the Fiber Glass currently used on the market are polyurethane, and the fire incident at the Capital Airport was related to polyurethane materials.

As far as current market applications are concerned, due to doubling the cost and time-consuming labor, very few use inorganic temperature materials. In contrast, B-class materials, mainly polyurethane and styrene board, are very popular. Document No. 65 was also considered to be beyond the capabilities of existing resources and technologies and had poor operability. After its promulgation, building insulation projects nationwide came to a standstill. At present, it is generally expected in the industry that relevant fire protection standards will lower the flame retardant level of glass yarn. It is unlikely that inorganic glass yarn with a high fire protection level will be recognized because it not only complies with building energy conservation but also meets safety standards. And strengthen the management of construction enterprises and strictly implement the acceptance system.
The standardized use of glass yarn is not a one-day effort, and a single government decree cannot completely prevent the slightest change. But overall, it is urgent to implement fire protection standards as soon as possible. The new fire protection policy is pending, and the construction of exterior wall grids in many real estate projects is currently suspended. Not only that, manufacturers of inorganic Fiber Glass are also looking forward to it.
