In recent years, extruded boards have been widely used in the manufacturing industry, and their sales volume has gradually increased in recent years. At this time, many illegal enterprises saw business opportunities and chose recycled materials to manufacture extruded boards. Although relevant departments have strictly controlled such items, there are still a large number of recyclable materials in circulation in the market. Recycled material extruded insulation boards have many disadvantages. Below, let us analyze the hazards of extruded boards, hoping to be helpful to you. Hazards of plastic extruded board recycled extruded board: 1. Building material safety and environmental protection materials are widely used in low-quality extruded boards, which have poor thermal insulation effects in high-temperature environments, leading to heat loss. Inferior products have low strength, poor rebound and compression properties. It will cause long-term ground subsidence and cracking. 2. Recycled extruded boards contain various impurities and cannot form a closed-cell structure, and can absorb water under capillary action. Long-term contact and inhalation of fungal spores may cause respiratory diseases and allergic symptoms. 3. Excessive bacteria To make extruded boards have better performance, such as enhanced flexibility, various plasticizers and stabilizers are added, which will bring long-term and lasting hazards to human health and the natural environment. Once entering the human body, it will cause cumulative lead poisoning. 4. Health hazards Recycled plastics contain various chemical substances, such as anti-aging agents and colorants, but in fact, plastic stabilizers, such as lead stearate, are easy to precipitate and harmful to human health.
Generally speaking, recycled material extruded boards cannot be used in construction sites such as exterior wall insulation and roof insulation. For the protection of waterproof layers in some residential areas, they can play a certain role, effectively preventing the waterproof layer from being damaged during backfilling operations.
