What Are the Bonding Parameters of Vacuum Diffusion Bonding? What Are Their Effects? The main bonding parameters of vacuum diffusion bonding are: temperature, pressure, heat preservation diffusion time and protective atmosphere, diffusion bonding of materials with phase change and ceramics and other brittle materials during the cooling process, and the heating and cooling speed should

The domestically produced printed plate heat exchanger (PCHE) produced recently passed the factory acceptance. Up to now, the product has set a domestic record in four aspects: power size, design temperature, pressure resistance range, and structural size. PCHE is a subversive compact and efficient micro-channel heat exchanger. This kind of heat exchanger has the advantages
