How long will the “Dream Construction Materials” ravage?

It is reported that: It has been verified that a large number of polyurethane foam insulation materials wrapped in the facade of the building during the “11.15” major fire in Shanghai is an important culprit in causing heavy casualties. This kind of material burns very fast, and once it burns, it produces highly toxic gas, which can seriously damage the lives of people in building fires.

This is not the first time that "destruction of building materials" has raged. In some of the most serious fire accidents that have occurred in recent years, there are phantoms of flammable and highly toxic decoration materials. What is incredible is that many flammable and highly toxic building materials actually enter the building materials market under the banner of permission from relevant departments. The polyurethane foam insulation materials, which have been widely criticized and repeatedly hit, are actually promoted by the relevant departments.

Many experts told reporters that the current domestic building materials market, especially the thermal insulation material confusion has been shocking, if not determined to rectify norms across the country, expect a city, a province to "keep the wall clear" to achieve self-protection, it is impossible. It is understood that the insulation materials used in the domestic market can be divided into two major organic and inorganic categories, inorganic materials are basically incombustible, and organic materials including polyurethane foam are flammable products, and can only be achieved after the addition of flame retardants. Flame retardant "level. In fact, many domestic construction companies often use insulation materials without flame retardants for profit maximization, and the relevant departments have not yet imposed mandatory inspections.

The cost of blood is paid year after year. Why did the relevant departments delay the ban on these "destructive materials" and allow them to enter the market? “The people of Qin don’t mourn and mourn, but later generations mourn and miserable, and also make their descendants mourn for later generations.” Looking at the real people-centered approach of the relevant departments, they will rectify the chaotic building materials market and resolutely Life building materials" cleared out.
