The main function of the edge banding is to seal the cross-section of the board, so as to avoid the damage of the board and the adverse factors (mainly moisture) in the process of use and prevent the formaldehyde inside the board from volatilizing, and at the same time achieve the effect of beautiful decoration.
The product has the following main features: smooth surface, no blistering, no ribbing, moderate gloss, smooth surface and back surface, uniform thickness, uniform width, reasonable hardness, high elasticity, good quality, strong wear resistance, trimmed and sealed The color of the side and the side is close to the surface color, not whitish, good gloss, and the overall color of the finished furniture is coordinated.
PVC furniture edge banding is relatively light, which is relative to metal and plexiglass. The reason for the lightness is not because it is a polymer compound, but because they are organic compounds, which are composed of carbon, hydrogen, oxygen, and chlorine. And other lighter elements.

The design pressure of this hydrostatic test is 17.2 MPa. The hydrostatic test is divided into two stages: the pressure test of the pressure vessel body and the internal and external O-ring leakage test. The overall hydrostatic test pressure is 21.5 MPa and the holding pressure time is 10 minutes. When the pressure dropped to 17.2 MPa, the internal and external O-ring leak test was conducted. During the hydrostatic pressure test, all the indicators met the design requirements, and there was no leakage or sweating during the entire process.
The hydrostatic test was successfully completed at one time, indicating that the CAP1400 reactor pressure vessel independently designed and developed by China has been domesticated, laying a good foundation for the mass production of the three generations of nuclear power.
The reactor pressure vessel is the core equipment of the nuclear power unit and is the most important safety barrier for containing radioactive materials. It is not replaceable during the 60-year life cycle, and its advanced nature is crucial to ensure the safety and reliability of nuclear power plant operation. The reactor pressure vessel is independently designed by the National Nuclear Power Institute of Shanghai Nuclear Power and independently manufactured by China. It adopts an integrated roof and an integrated bottom head to reduce the number of welds, greatly reducing the workload of in-service inspections, and improving nuclear power. Plant safety and economy. In addition, the reactor pressure vessel forgings have large diameter size, high performance requirements, and overall heavy weight, and are one of the world's most demanding nuclear primary equipment.

The material of pvc furniture edge banding is plastic, which is easy to process. Plastic has plasticity, that is, it deforms after heating or pressurizing, and maintains its original shape after the temperature drops or the pressure disappears. It can be processed into edge bands of their respective shapes by extrusion and other methods, such as T-shaped edge bands, H-shaped edge bands, D-shaped edge bands, V-shaped edge bands, I-shapes, and so on.
pvc furniture edge banding is of high quality and low price, and the price of plastic is far less than that of metal.
China's independently developed CAP1400 reactor pressure vessel passed the test successfully
[China Instrument Network Instrument R&D] On March 17, 2017, under the support of the “National Large-scale Advanced PWR and High-temperature Gas-cooled Reactor Nuclear Power Plant†national science and technology major project, the hydrostatic pressure test of the reactor pressure vessel of Unit 1 of the CAP1400 demonstration project was successfully completed.
