What should I pay attention to when choosing boards?
Environmental rating? Brand name?
Or sales ranking?
All of these require attention
If you want to advance and choose a durable board
Also pay attention to these -
Static bending strength and elastic modulus
What is static bending strength
01
The static bending strength is the ratio of the bending moment and the bending section modulus of the plate when the maximum load is applied.
02
Static bending strength is an important property that determines whether furniture will bend or even break during use.
03
Static bending strength is a key index to measure the deformation, cracking and other problems of the board in the later stage, which affects the probability of damage and service life of the finished furniture during use.
Simply put: the static bending strength value of the board product we see in the product report is the pressure strength that the board can withstand when it is bent under force to the point of breaking. There are many factors that affect the static bending strength of the board, and raw materials, tree age, processing technology, etc. are all important factors.
For example:
For example, this high cabinet wardrobe that reaches from one cabinet to the top. As an important storage space, the wardrobe is under the pressure of hanging and placing objects for a long time. If the static bending strength of the board does not meet the requirements, deformation and cracking will still occur even if a straightener is added.
How to make a Millennium Boat?
The raw materials and production process of the plate are the two key factors affecting the static bending strength of the plate. To improve the static bending strength of the plate, Qiannianzhou does this↓↓↓
Selected high-quality raw materials:
If the logs are too young, the static bending strength of the boards will be low. Qiannianzhou selects high-quality pine tree sections that are over 20 years old, have a few branches, are round and straight, have few boils and few wormholes, and are in their golden age. This lays a solid foundation for the high static bending strength of the boards.
Continuously optimize hot pressing machinery and processes:
Reasonable production processes, such as hot pressing, can make the sheet material more stable and less susceptible to warping and deformation. Qiannianzhou has introduced the ninth-generation continuous press from Germany's Siempelkamp, which uses high-temperature and high-pressure one-piece molding. This allows for more precise pressure distribution and more uniform sheet density, resulting in a continuously stable finished product structure with higher static bending strength.
No nonsense! Quality speaks for itself
According to the authoritative quality inspection report, the average and minimum static bending strength of Qiannianzhou panels are far higher than the required values and meet the national standard requirements.
Let's be more intuitive and conduct a real-life experiment to verify the quality of the board:
Samples of Qiannianzhou board were selected and subjected to pressure using a machine until the boards deformed. The results showed that the average static bending strength of Qiannianzhou LSB high-energy home furnishing boards reached 15.0 MPa, far exceeding the standard of 11.5 MPa and equivalent to the strength of two adult men weighing over 150 kilograms.
Meeting standards is essential, and stability is even more crucial. For boards, the higher the "static flexural strength" index, the greater their resistance to bending damage. Qiannianzhou Healthy Boards utilizes premium pinewood, formaldehyde-free MDI-based eco-glue, and utilizes advanced intelligent manufacturing techniques to create high-quality boards. The finished product's static flexural strength and elastic modulus far exceed national standards, making it remarkably resistant to deformation and the need for straighteners, making it easy to create full-length tall cabinets.
