Why is it suitable to use odorless E0 grade environmentally friendly particleboard in schools
source:m.sanjiachina.com Time:2025-11-17
       The school is suitable for using odorless E0 grade environmentally friendly particleboard. The core reason is that it meets environmental standards without harm, its performance is suitable for campus scenes, its cost-effectiveness is high, and it can meet the health and teaching needs of teachers and students. The specific reasons are as follows:
1. Environmentally friendly and odorless, safeguarding the health of teachers and students
        E0 level is a high standard for environmental protection, with low formaldehyde emissions (usually ≤ 0.124mg/m 3), which meets the indoor environmental protection requirements of the campus. The odorless characteristic avoids the impact of unpleasant odors on the classroom environment and the respiratory tract of teachers and students, especially suitable for groups with weaker immune systems such as primary and junior high school students, reducing the potential harm of harmful substances such as formaldehyde to health and creating a safe learning and living space.
2. Performance adaptation for high-frequency campus usage scenarios
       The particle board structure is uniform, with good load-bearing capacity and stability, which can meet the needs of campus furniture such as desks, chairs, storage cabinets, book racks, laboratory workstations, etc. Its surface is flat and can be directly covered with leather or spray painted, suitable for the diverse design of campus furniture. It has strong wear resistance and deformation resistance, and can cope with high-frequency use and movement by students, extending the service life of furniture.
3. High cost-effectiveness, suitable for campus bulk procurement
        Compared to solid wood panels, odorless E0 grade environmentally friendly particleboard is more affordable, and bulk purchasing can significantly reduce the cost of campus furniture procurement, which meets the needs of reasonable budget planning for schools. At the same time, its production process is mature and the supply is sufficient, which can quickly meet the large-scale furniture configuration needs of multiple scenarios such as teaching buildings, dormitories, libraries, etc., and the subsequent maintenance is simple, reducing the cost of campus logistics management.
