What should you pay attention to when choosing boards?
Environmental rating? Brand name?
Or is it the sales ranking?
All of these require attention.
If you want to go for a more advanced option, choose a durable board material.
We also need to pay attention to these things-
static bending strength and modulus of elasticity
What is static bending strength?
01
Static bending strength is the ratio of the bending moment to the section modulus of bending of a sheet material under maximum load.
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 for measuring the deformation and cracking of boards in the later stages, which affects the probability of damage and service life of finished furniture.
In simple terms: the static bending strength value of a board product that we see in the product report is the pressure strength that the board can withstand when bent under stress until it breaks. There are many factors that affect the static bending strength of a board, such as raw materials, tree age, and processing technology.
For example:
For example, this floor-to-ceiling tall wardrobe is an important storage space that is subjected to the pressure of hanging and placing items for a long time. If the static bending strength of the board does not meet the requirements, even with the addition of a straightener, problems such as deformation and cracking will still occur.
How to make a Millennium Boat?
The raw materials and production process of wood-based panels are two key factors affecting their static bending strength. Here's how Qiannianzhou improves the static bending strength of its panels: ↓↓↓
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 logs that are over 20 years old, with a few branches, are round and straight, have few knots and wormholes, and are in their prime age, laying a solid foundation for the high static bending strength of the boards.
Continuous optimization of hot pressing machinery and processes:
Optimized production processes, such as hot pressing, can make the sheet material structure more stable and less prone to warping and deformation. Qiannianzhou has introduced the ninth-generation continuous press from Simberlcombe in Germany, which uses high temperature and high pressure for integrated molding. This results in more precise pressure distribution, more uniform sheet material density, and a more stable finished product structure with higher static bending strength.
No empty promises! Quality speaks for itself.
According to authoritative quality inspection reports, the average and minimum static bending strength of Qiannianzhou boards are far higher than the required values, meeting the national standard requirements.
To make it even more intuitive, let's conduct a real-world experiment to verify the quality of the board material:
Samples of Qiannianzhou LSB high-energy home furnishing boards were selected and pressure was applied to the boards using a machine until they 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, equivalent to two adult men weighing over 150 kilograms each.
Meeting standards is a must, but stability is an upgrade. For wood panels, the higher the "static bending strength" value, the stronger their resistance to bending damage. Qiannianzhou Healthy Wood Panels selects high-quality pine wood and uses formaldehyde-free MDI eco-friendly adhesive, employing advanced intelligent manufacturing processes to create high-quality panels. The finished product's static bending strength and modulus of elasticity far exceed national standards, making it less prone to deformation, eliminating the need for straighteners, and easily creating full-length tall cabinets.
