Wear Layer

A wear layer, usually made of a durable material like aluminum oxide or melamine, is then added on top of the decorative layer. This wear layer provides protection against scratches, stains, and fading.

Pressing and Heating

The assembled layers are placed in a press where heat and pressure are applied. This process ensures that the layers bond together securely.

Cutting and Finishing

After the pressing process, the laminated sheets are cut into desired sizes and shapes. The edges are often sealed to prevent moisture penetration. Eco-friendly laminate may use non-toxic edge sealers or edge banding made from sustainable materials.

FAQ

 

Q: What are the core raw materials of environmentally friendly magnesium oxide boards?

A: They are based on natural inorganic minerals such as magnesium oxide and magnesium chloride/magnesium sulfate, with the addition of renewable plant fibers (e.g., straw fibers) and inorganic mineral fibers. No harmful chemicals like formaldehyde or benzene are added throughout the process.

Q: In which links is their environmental friendliness reflected?

A: It covers the entire life cycle: green raw materials are used in production with low energy consumption and no pollutant emissions; no harmful substances are released during use; they can be degraded or recycled after disposal, forming an environmental protection closed loop.

Q: What standards do their formaldehyde emissions meet?

A: They are far below the national standard, usually ≤0.05mg/m³, and some high-quality products even reach the "zero formaldehyde" level, making them suitable for scenarios with extremely high health requirements such as hospitals and schools.

Q: Can they be used in humid environments?

A: Yes. The crystalline phase formed by their components has strong water resistance, with only a small decrease in strength after absorbing water, and they are not prone to mildew. They are superior to traditional gypsum boards and suitable for humid areas such as bathrooms and kitchens.

Q: Does the production process consume a lot of energy?

A: No. It adopts low-energy-consuming processes such as room-temperature curing, without the need for high-temperature calcination. Carbon emissions are much lower than those of traditional building materials like cement boards and ceramic boards, meeting the requirements of low-carbon production.

Q: Do they pass authoritative environmental certifications?

A: Regular products usually pass certifications such as LEED and China Green Building Material Certification, with clear marking of environmental indicators, and can be used as preferred materials for green building projects.

Q: What is the core difference between them and ordinary magnesium oxide boards?

A: Environmentally friendly ones are superior to ordinary ones in terms of raw material purity (no harmful additives), production processes (low consumption and low emissions), health and safety (extremely low formaldehyde), and recyclability (easy to recycle).

Q: How to dispose of them after disposal?

A: Due to their main components being inorganic minerals and degradable fibers, they can be naturally degraded or crushed and reprocessed as raw materials for production, reducing construction waste pollution.
