Polymer diffusion welding is a technology applied in the manufacture of products, and its main role is to join two or more polymer materials together to form a monolithic structure.
By the action of high temperature and pressure, the material is melted and spread over the welded interface, causing it to fuse with each other to form a strong connection.
1.Principle of Polymer Diffusion WeldingPolymer diffusion welding is a solid-state joining technology that offers many advantages over traditional melt welding.
The principle is that two or more polymer products of the same material are heated to degrade their surfaces and produce a viscous solution.
The two materials are then brought together and pressure is applied to them so that the solution spreads across the contact surface, and the connection is achieved by exchanging atoms and molecules.
2.Advantages of polymer diffusion welding 21. High-strength connection:
Polymer diffusion welding can form a high-strength connection on the joint surface of the material, which can withstand large tensile forces and pressures.
2.2 No additives:
Compared to other joining technologies, polymer diffusion welding does not require the use of any adhesives or welding materials, resulting in a purer joint without impurities.
2.3. No pollution:
Polymer diffusion welding will not produce harmful gases and wastewater, has no pollution to the environment, and meets environmental protection requirements.
2.4. High efficiency and energy saving
Since the joining process of polymer diffusion welding is solid, no additional energy is required for heating and cooling, saving energy.
3.Application areas of polymer diffusion welding 31. Automobile manufacturing:
Polymer diffusion welding can be used for the connection of automotive parts, such as body panels, interior trims, etc.
It can provide a strong connection that improves the safety and durability of the car.
3.2 Electronics:
