Maineng Environmental Protection Yellow Board is targeted for the high humidity, high load, and high insulation needs of floor heating scenes. Through raw material control and process innovation, it solves the pain points of traditional extruded boards in floor heating applications. The following is an analysis based on technical characteristics and scenario adaptability:
1. Environmentally friendly upgrades of raw materials and processes
1. Pure raw material system
Core ingredients: Polystyrene (PS) is used as the single main material, without adding plasticizers or chemical blowing agents (such as chlorofluorocarbons), avoiding the release of harmful substances from the source, and meeting the environmental health requirements of floor heating (especially suitable for home scenes).
Environmentally friendly process: Using carbon dioxide (CO) physical foaming technology, the foaming process has no chemical pollution, and the production process is low-carbon and energy-saving, which conforms to green building standards.
2. Structural performance optimization
Cell structure: Through process control, a uniform and fine closed cell structure (cell diameter is about 0.1-0.3mm) is formed, with a closed cell ratio of ≥95%, which is denser than traditional extruded plates (closed cell ratio of 85%-90%)., structurally blocking the water penetration path.
2. Adaptation of core performance of floor heating scenes
1. Ultra-low water absorption to resist moisture and mildew
Data comparison:
Maineng Environmental ProtectionHuangThe water absorption rate of the board is ≤1.0%(the floor heating industry standard requires ≤3.0%), which is much lower than that of ordinary extruded board (1.5%-3.0%).
Actual value:
The floor heating system has been located between the concrete layer and the soil for a long time. The environmental humidity is high and the low water absorption rate can prevent the board from softening and mildew after absorbing water, prevent mold from being released indoors through ground gaps, and ensure air quality.
Reduce the increase in thermal conductivity caused by water absorption (the thermal conductivity of moisture is 0.58 W/(mK), which is more than 20 times that of polystyrene) and maintain long-term stability of thermal insulation performance.
2. High compressive strength prevents ground subsidence and cracking
Performance parameters: Compression strength reaches 200 kPa (higher than the requirement of "extruded sheets for floor heating ≥150 kPa" in national standard GB/T 10801.2-2020), and can withstand a load of about 20 tons per square meter.
Application scenarios:
Suitable for home floor heating (normal load is about 10-15 kPa) and commercial places (such as office buildings and shopping malls, with loads up to 20-30 kPa) to avoid cracking of floor tiles/floors due to compression and deformation of the plates.
Compared with ordinary extruded boards (compressive strength 100-150 kPa), they have significant advantages under high loads (such as laying stone floors), which can reduce the thickness of the backfill layer and reduce construction costs.
3. Low thermal conductivity improves energy-saving efficiency
Thermal performance: Thermal conductivity ≤0.034 W/(mK)(≤0.035 W/(mK) specified in national standard GB/T 10801.2-2020), and the insulation effect is increased by about 3% under the same thickness.
Energy-saving calculation: Taking a floor heating area of 100㎡ as an example, using Mineng energy-saving yellow board (thickness of 20mm) can reduce heat loss by about 1200 kWh per year compared with ordinary extruded board (thickness of 20mm, thermal conductivity of 0.035 W/(mK)). Calculated based on the residential electricity price of 0.5 yuan/kWh, the annual saving is about 600 yuan.
In long-term use, low thermal conductivity characteristics can delay performance degradation caused by material aging and continue to reduce operating costs.

4. Construction and maintenance recommendations
Key laying points:
Joints of plates need to be sealed with tape to avoid local stress concentration caused by infiltration of concrete slurry.
In areas with extremely high humidity such as toilets, it is recommended to add a moisture-proof film under the insulation board to further block moisture.
Adapt scenarios:
Priority is given to home floor heating, villas, kindergartens and other scenarios that require high environmental protection and durability; commercial scenarios (such as gyms, parking lots) need to choose enhanced models with compressive strength ≥300 kPa.
Testing and certification:
It is recommended to check the product's thermal conductivity test report (GB/T 10294), water absorption test report (GB/T 8810) and compressive strength test report (GB/T 8813) to ensure that the performance meets the standards.
Summary
Through the triple upgrade of pure raw materials + environmentally friendly processes + structural optimization, Maineng Environmental Protection Yellow Board accurately solves the core pain points of floor heating scenes, especially in terms of moisture resistance, pressure resistance, and energy conservation. It is the preferred solution for pursuing long-term stability, health and environmental protection. For decoration projects that focus on quality, its comprehensive cost performance ratio (slightly higher initial cost but long-term energy saving + maintenance-free) is significantly better than traditional extruded boards.
