How to choose engineering board materials? Just read this article!

Building materials are a general term for materials used in civil engineering and construction. The production, sales, and distribution of these materials are considered the building materials industry. Building materials, typically flat, rectangular panels of standard sizes used as wall, ceiling, or floor components, are collectively referred to as building panels.

As the country pays more and more attention to the green development of the construction industry, a variety of "green building materials" have emerged to help the industry develop with high quality, implement sustainable development and green development policies to help the industry develop.

So, what should we pay attention to when selecting boards for construction projects?

Question: “How to choose flame retardancy when selecting panels for engineering projects?”

For engineering use, national acceptance standards must be considered. The current market for flame-retardant panels is a mixed bag. Some panels are simply a layer of fire-retardant coating sprayed on the wood surface, while others may not even be sprayed. Such panels simply cannot pass inspection. Therefore, brand assurance is crucial for flame-retardant panels used in engineering applications.

Flame-retardant panels available on the market can be divided into four grades based on their flame retardancy: A (A1, A2) for non-combustibility, B1 for flame-retardant resistance, B2 for flammable resistance, and B3 for highly flammable resistance. This classification clearly illustrates the differences in the flame-retardant properties of these panels. As industry requirements for building fire safety continue to rise, choosing panels with high flame retardancy ratings can effectively improve building fire safety.

For non-combustible building materials with higher requirements, A1 grade boards can be selected, which almost do not burn.

The Zhongjing board series products are A1 non-combustible for baseboard products and A-class non-combustible for decorative boards, the highest flame retardant grade among flame retardant boards. They are the perfect choice for engineering flame retardant boards.

“How to choose environmentally friendly materials?”

The environmental friendliness of a material is primarily determined by its formaldehyde content, asbestos content, and TVOC emissions. The lower the content, the more environmentally friendly it is. Furthermore, a higher smoke toxicity rating means the board will produce toxic smoke later in a fire, providing more opportunities for fire escape.

• Formaldehyde: A colorless, odorless, and invisible gas, it's a terrifying threat. my country's standard for formaldehyde in artificial wood panels is 9mg/100g dry wood, meaning 9mg of free formaldehyde is permitted per 100g of dry wood. Formaldehyde emissions are an important consideration when purchasing. Medium-crystal board emits only 0.029mg/m³, exceeding the international environmental protection grade E0 requirement.

• Asbestos: Asbestos is a tough material, highly resistant to heat, fire, abrasion, and chemicals. Therefore, from a building material perspective, it's an excellent thermal insulation and fireproofing material. However, as a carcinogen to the human body, asbestos fibers can damage healthy lung cells, so asbestos content is a concern when purchasing board materials. Our Zhongjing board series products have no detectable asbestos content and are asbestos-free.

• TVOC: TVOC is one of the most serious pollutants affecting indoor air quality. According to the national standard "Residential Design Code" (GB50096-2011), residential indoor air pollutant limits stipulate that indoor TVOC emissions in Class I buildings should be ≤0.5mg/m³. Zhongjing panels emit ≤0.06mg/m³, far below the national requirement.

• Smoke toxicity: The smoke toxicity of a material is determined by heating the sample at a constant speed in a ring furnace with a stable heat supply, allowing the material to decompose and burn steadily, thereby producing a stable smoke flow. The lower the required smoke concentration, the higher the smoke toxicity risk. Conversely, the higher the required smoke concentration, the lower the smoke toxicity risk. AQ1 is the highest safety level, and the Zhongjing board series products have an AQ1 safety level for smoke toxicity.

Zhongjing board series products have all obtained environmental certification certificates, including the China Ten-Ring Certification commonly used in China, the CE certificate recognized in the EU region, and the French A+ certification recognized by both Europe and the United States. They are able to meet the strict environmental protection testing requirements of different regions and are green and environmentally friendly boards that are best-selling in the world.

Question: “How do I choose materials to reduce costs and increase efficiency?”

The Zhongjing board product series, including the baseboard, is an A1-grade, non-combustible, lightweight, high-strength, smooth-surfaced, and superior-performance lightweight inorganic board material suitable for putty-free construction and industrial press lamination. It can be fixed with nails or cut by hand, offering convenient installation and superior performance. During on-site construction, the baseboard's superior performance allows it to replace a variety of board materials, reducing confusion caused by a wide variety of product options. This allows for "one board for multiple uses," saving time and increasing efficiency. The Jingtu and Jinghua series not only replace traditional stone and paint, perfectly recreating the design effect, but also significantly reducing material costs. Their simple and efficient application system, optimized for a light steel keel adhesive system, reduces on-site construction complexity, allows workers to quickly master the system, and effectively improves on-site construction efficiency, thereby reducing overall costs.

In the tide of low-carbon development, "green" has become the main theme of future exploration and development in various industries. Zhongjing Building Materials, with its Zhongjing board series products, has come to meet the market's huge demand for new environmentally friendly building materials. With technology as the foundation and products as the priority, it has helped the construction and building materials industries to develop with high quality and become a high-quality partner for all sectors inside and outside the industry.

With production bases spanning North, East, and South China, the company has been awarded titles such as "High-Tech Enterprise" and "Young Eagle Enterprise," and its research center has been selected for inclusion in Tianjin's list of joint laboratories for the Belt and Road Initiative. Zhongjing Building Materials Group, adhering to the development trends of "industrialization, greening, and informatization" and adhering to the self-imposed goal of "green intelligent manufacturing, industrialized production, and prefabricated construction," is promoting the upgrading of new approaches to building development with unprecedented energy and momentum.
