Welding nut is a kind of nut suitable for welding outside the nut. It is generally made of weldable material and is relatively thick and suitable for welding. Welding is equivalent to turning two separated parts into a whole, melting the metal at high temperature, mixing it together and then cooling it. Alloy will be added in the middle, and molecular force will play a role in the inside, and the strength is generally greater than that of the parent body. The experiment of welding parameters depends on the fusion size of the weld, and the welding parameters are adjusted according to the fusion size until the defects are eliminated. Of course, the quality of welding is related to the pre-welding treatment, such as dust removal and oil stain.

Analysis of market prospects of polymerized polystyrene board
In 2013, China's real estate sector was expected to gradually stabilize. The demand for housing remained strong, and after two years of market pressure and hesitation, a rebound was inevitable. The development of affordable housing became a key focus for the new government, while ongoing urbanization provided long-term support for the real estate industry. Additionally, energy-saving renovations of existing buildings were gaining momentum across the country. Overall, the exterior wall insulation industry in China represented a massive and promising market.
Over the years, the building insulation sector had faced numerous challenges, particularly in balancing fire safety with energy efficiency. Past practices that prioritized energy conservation over fire prevention led to significant issues, while recent overemphasis on fire safety introduced new risks. This back-and-forth highlighted the need for a more balanced and reliable solution.
EPS polystyrene boards have been widely used abroad for over six decades and have been in China for more than 20 years. Known for their high energy efficiency and cost-effectiveness, they hold an impressive 80% market share in China. However, their flammability has always been a concern.
Now, Yada Construction New Materials (Shanghai) Co., Ltd. has addressed this challenge by combining traditional EPS polystyrene boards with advanced inorganic materials. This innovation has resulted in AEPS (Advanced Expanded Polystyrene), which significantly improves fire resistance. The combustion grade has been upgraded to A2, making it much safer. When tested with a 1000-degree flame for several minutes, the material does not burn, produce droplets, or emit smoke. It eliminates the major flaw of traditional EPS—lack of fire protection—while preserving all its advantages.
Undoubtedly, the new AEPS board is set to gain widespread recognition in the market. Considering factors such as fire resistance, energy efficiency, safety, and cost-effectiveness, it represents an ideal thermal insulation material today. With its superior performance, it is well-positioned to reshape both the organic and inorganic insulation markets.
