Hot-melt flux is a flux that produces high temperatures through the thermite reaction of several chemical substances and achieves the purpose of welding through mold investment. At high temperatures of ℃, the same or different metals such as copper and copper, copper and steel are completely welded to achieve true molecular bonding, making the grounding device a permanent maintenance-free grounding device. Hot melt flux is the product of Hengtai Company Products that have obtained three national patents. The hot melt flux has been tested by the State Electric Power Corporation and Wuhan High Voltage Research Institute many times and has reached the testing standards. It is the first high-tech product in China to produce and pass national testing. Hot melt flux has the following advantages: The current carrying capacity of the welding point is the same as that of the conductor, and it has good conductive properties. After testing, the DC resistance ratio change rate before and after welding is close to zero. This is unmatched by any traditional connection method. , does not require external energy, and can be operated indoors and outdoors. , will not be damaged by surge current. Tests have shown that under the impact of a short period of large current, the conductor melts before the welding joint. , Welding will not cause corrosion and relaxation. Because it is a fused joint, there are no contact surfaces and no residual stress, making the joint stable and reliable as a long-term conductor. , Because it is a fused joint, the joint and the conductor are molecularly bonded. Therefore, it has good mechanical strength and is a permanent joint. , The equipment is simple, lightweight, easy to carry and easy to operate, and does not require professional operators.
The hot-melt flux welding method uses the reaction between compounds to generate high temperatures, and the molten metal reaches the welding part through the investment mold and forms a permanent joint with a certain shape and size that meets the process requirements. This method can weld copper and copper, copper and steel, copper and galvanized steel, the same metal or different metals.
In order to weld between conductors of different specifications and types, a special mold needs to be made for welding. Fix the two ends of the conductor to be welded in a mold, put in the hot-melt flux, ignite the ignition powder, and the reaction will produce a high temperature that melts the powder into a liquid. After cooling, open the mold, and the welded conductor becomes a permanent connection. Cangzhou Hengtai Lightning Protection Equipment Co., Ltd. has corresponding matching molds for different hot melt flux specifications.
Performance characteristics of hot melt flux:
.Large current load capacity
The current carrying capacity of the welding point is the same as that of the conductor, and it has good conductive properties. After testing, the DC resistance ratio change before and after welding is close to at zero. This is unmatched by any traditional connection method.
.Good mechanical properties
Because it is a fusion joint, the joint and the conductor are molecularly bonded, and it is a permanent joint.
. Stable impact resistance
Experiments have shown that under the impact of a short-term large current, the conductor melts before the joint, so it will not be damaged by the surge current.
. Strong corrosion resistance
Because it is a fused joint, there is no contact surface, no residual stress, and the joint is covered with pure copper, which greatly enhances the corrosion resistance of the conductor.
.Freely control the reaction temperature
No need for external energy, no special equipment, no professional operators, it can be operated indoors and outdoors, and the time to complete the entire connection process is short.
.Simple and safe connection
Different reaction temperatures can be configured according to the metal characteristics of the conductor to be welded, making the welding joint stronger and more complete.
Precautions when using hot melt solder:
． Each package of welding agent corresponds to one welding joint. The welding agent model must be consistent with the welding agent model indicated on the mold nameplate. Please check carefully before use.
． The welding agent has multiple layers of protection against moisture when it leaves the factory, but it is recommended that it be properly stored to avoid moisture.
◇ Preparation work before using hot melt solder:
． Before each operation, use a heating tool (blowtorch) to heat and dry the mold to remove moisture in the mold. Molds that have not been used for a long time contain moisture, especially molds that still have residue after the previous use.
． To clean the mold, use a soft-bristled brush or other soft object.
． Check the tightness of the mold contact surface to prevent copper liquid from leaking from the gaps during operation.
． The mold clamp is used to open and close the mold. The tightness of the mold clamp directly affects the welding effect. Please check the mold clamp carefully before starting and make appropriate adjustments to adjust the tightness of the mold clamp to the mold to the maximum. Best condition.
