1. Excellent physical performance
The density of mechanical bridge deck is 0.35-0.55g/cm3, while the density of flat-pressed door deck is about 0.75g/cm3. It can be seen that the density of mechanical bridge deck deck is lower than that of flat-pressed particleboard.
The quality of the door core plate can be greatly reduced by using the mechanical plate of the bridge hole, and it can be reduced by 60%.The mechanical plate of bridge tunnel has good thermal insulation and sound insulation performance. The hollow plate of 40mm thickness is equivalent to the thermal insulation effect of 300mm thick brick wall, and the sound insulation is up to 28 dB.Its compressive resistance is good, and it will not deform under the pressure of 2MPa.Due to the particularity of bridge mechanical plate manufacturing process, the water absorption expansion rate (TS) of the product in the thickness direction is very small, almost comparable with the radial shape variation of wood.
Although the longitudinal static strength of the bridge mechanics plate produced by extrusion method is very low and the water absorption expansion rate of the length direction is high, the longitudinal static strength of the 3mm veneer can fully meet the national standard requirements of ordinary particleboard.
The mechanical bridge deck is only used as the core plate, which has certain requirements on its thickness. It will be coated when used, and it is only used in the dry environment. The water absorption expansion rate in the direction of its length will not affect its use.
Compared with ordinary hollow particleboard, high performance hollow particleboard can absorb water and expand
A significant result of the current low water absorption expansion of the hollow particleboard has been maintained in E1
Green glue,
Low density high strength performance, at the same time linear (orifice direction) water absorption expansion rate control low, solve the wooden door using hollow particleboard deformation problem.
We are here to explain why we are high performance hollow particleboard!
The density of hollow particleboard is 0.35-0.55g/cm3, while that of flat door is about 0.75g/cm3
, it can be seen that the density of hollow particleboard is lower than that of flat pressed particleboard.Therefore, making door core board with hollow particleboard can greatly reduce the quality of door board,
And can be reduced by 60% at most;Hollow particleboard has good thermal insulation and sound insulation performance, 40 mm
A thick hollow core is equivalent to 300
mm
Thick brick wall insulation effect, sound insulation up to 28 decibels;Its compressive resistance is good, and it will not deform under the pressure of 2MPa.Due to the special manufacturing process of hollow particleboard, the water absorption expansion rate (TS) of the products in the thickness direction is very small, almost comparable with the radial shape variation of wood.
Hollow particleboard (also known as bridge mechanics board)
As an innovation in the manufacturing technology of door core board,
To be a bright spot of inner door manufacturers' products.Bridge deck mechanics using the principle of arch bridge bridge deck, through high-tech processing,
A unique tubular structure made of solid wood sawdust can be combined
The external force is evenly distributed to ensure no deformation, because the weight is less than half of the solid wood of the same size, the light texture can also avoid the deformation caused by too heavy hinge and door cover,
Extend service life.At the same time, the mechanical deck of the bridge acts like a vacuum flask, preventing the diffusion of temperature.
Keep a pleasant temperature in summer and winter.
We are a company specializing in the new wood-based material of hollow particleboard, with the production line of hollow particleboard press with good technology. The first phase of the project has been completed and put into operation, and the second phase of the cross-hole wide-width press has been put into operation in March 2017, with an annual capacity of 100,000 cubic meters.Hollow particleboard is a new generation of green environmental protection material developed in China's wood-based panel industry in recent years. With advantages of light weight, heat insulation and sound insulation, good impact resistance and low cost, it is a good product for the replacement of traditional wood-based panel.The company's product quality standard has been in the international similar
The advanced level of the product, the company is currently working with domestic institutions of higher learning to research and develop new fire partition board project, after the completion of development will fill the technical gaps in the industry.The company always adheres to the tenet of scientific and technological innovation, actively advocates the concept of environmental protection, shows the authoritative recognition, reflects the assured quality, and seeks long-term cooperation with insightful people.
