In our lives, 90% of fire-retardant panels use public places and commercial real estate applications. There are not many people who know about them. There are also many types of flame retardant board, such as: flame retardant density board, fire retardant plywood, flame retardant blockboard and so on. The following millennium boat plate Xiaobian introduced the difference between fire-retardant plywood and fire-retardant MDF, and which is better:
First, fire retardant plywood:
Flame-retardant board (also known as flame-retardant board, fire-retardant plywood), flame-retardant plywood is rotated from the log into wood chips or wood planed into small wooden squares, the wood chips after the flame-retardant treatment and then glued together three Layers or layers of plywood, usually odd-numbered wood chips, and the adjacent layers of wood fibers from the vertical direction of the glue. Fire-retardant material boards produced from wood as the main raw material can substantially overcome the defects of wood due to its reasonable structure and fine processing of the production process, thereby greatly improving and improving the physical and mechanical properties of the wood, in addition to overcoming the common The disadvantage of plywood flammability has effectively improved the flame retardancy of plywood. Combustion board This board has five characteristics: flame retardancy, smoke suppression, anti-corrosion, insect resistance and stability. It can be said to have strong practicality.
Fire-retardant plywood has a very strong practicality. Maintained the excellent physical properties of plywood, processing performance and decorative features, Millennium boat flame retardant widely used in hotels, hotels, conference centers, convention centers, sports centers, libraries, transport passenger transport centers, leisure and entertainment venues, shopping malls, medical Institutions, office buildings and other public construction and renovation projects, high-end residential construction and renovation projects and high-end furniture manufacturing projects.
Second, the flame retardant density board:
In the production of high-performance density boards, special additives such as water repellent, fireproofing agents, antiseptics, etc. can also be added to manufacture special-purpose density boards. One of them is a flame-retardant density board, which is a functional board processed by applying a flame retardant during the production process of a density board. Density plates, also known as fiberboards, are man-made boards made from wood fibres or other plant fibers, using urea-formaldehyde resin or other suitable adhesives. The surface of the density plate is smooth and smooth, the material is fine, and the secondary processing is convenient. The thin veneer, paint paper, impregnated paper and rotary veneer can be pasted, and the internal structure is uniform, the density is moderate, and the stability is good.
Flame retardant density board has good physical and mechanical properties and processing performance, can be made into different thickness of the plate, it is widely used in furniture manufacturing, construction, interior decoration industry, shipbuilding, automotive lamp industry. The non-flammable medium density fiberboard is a homogeneous porous material with good acoustic properties and is a good material for the production of speakers, TV housings, and musical instruments. In addition, it can also be used for ships, vehicles, sports equipment, floors, wall panels, partitions, etc. instead of natural wood. It has the characteristics of low cost, simple processing, high utilization, and more economical than natural wood.
Third, the difference between fire-retardant plywood and fire-retardant MDF:
The difference between flame-retardant plywood and flame-retardant MDF is in the physical properties of the substrate. Flame-retardant plywood has high structural strength, stable performance, good load-bearing capacity, good nail holding force, low requirement for processing equipment, and easy processing. Flame-retardant MDF has the advantages of good surface smoothness and easy engraving and milling.
Fourth, fire-retardant plywood combustion performance classification According to GB8624-1997 "Building materials and products combustion performance rating", fire-retardant board is divided into, A-level non-combustible materials: A-level homogeneous material and A-class composite (sandwich) materials; Class B Combustible materials: B1 material and B2 material and B3 material. According to GB8624-2006 "Building materials and products combustion performance rating" is divided into: A1 level, A2 level, B level, C level, D level, E level, F level. The standard Class B1 flame retardant plate in 1997 can correspond to the standard 2006 Grade B and C flame retardant plates. However, the most common fire-retardant board in the plate market basically belongs to the Class B fire rating. Currently, the flame retardant board grades on the market mainly include: A1, A2, B, C four levels.
Fifth, flame retardant board environmental protection level
1. For the environmental standards for man-made boards, the State has established the “GB18580-2001 Limits for Formaldehyde Release in Interior Decoration Materials for Wood-based Panels and Productsâ€, in which E1 and E2 levels have been established based on the free formaldehyde emission limits for unit sizes.
E0 grade (formaldehyde emission ≤ 0.5mg/L): It is the European environmental protection standard adopted by the enterprise self-discipline.
E1 level (formaldehyde emission 0.5mg-1.5mg/L): It is the highest level of environmental protection in the national environmental protection standards and the lowest environmental protection level for interior decoration.
E2 grade (formaldehyde emission is greater than 1.5mg/L): generally used for outdoor decoration, but can not be directly used for interior decoration.
2. F-star certification in Japan is a series of wood products industry JAS series certification in Japan, divided into four levels, compared with the European E-level certification, is a progress, and its fundamental core is still formaldehyde emission, but Compared to the E-class standard, it has to be improved. There is a strict inspection requirement for the product to be inspected: the inspection area is not less than 0.18 square meters, and the sealing edge detection of the board is not allowed. The purpose is to ensure the most real amount of formaldehyde emission is detected. Let's take a look at the four levels of the F-star standard:
F★(≤5.0mg/L) Formaldehyde emission is less than or equal to 5mg per L
F★★(≤1.5mg/L) Formaldehyde emission is less than or equal to 1.5mg per L
F★★★(≤0.5mg/L) Formaldehyde emission is less than or equal to 0.5mg per L
F★★★★ (≤0.3mg/L) formaldehyde emission is less than or equal to 0.3mg per L
3, in the California Air Resources Board (hereinafter referred to as CARB) for wood composite products are divided into three levels, respectively P1, P2, and the highest NAF, NAF also called formaldehyde-free exemption certification. From January 1st, 2009, composite wood products that have not passed CARB certification and finished products containing composite wood products cannot enter the US market.
