Surface treatment method for increasing conductivity of aluminum conductive body for switch cabinet

Abstract

The invention relates to a surface treatment method for increasing the conductivity of an aluminum conductive body for a switch cabinet. The problems in the conventional surface treatment of the aluminum conductive body can be effectively solved, the conductive property is improved, and the electric transmission effects can be improved. The surface treatment method comprises the following steps of: firstly, preparing zinc soaking liquid, copper pre-plating liquid and copper plating liquid, wherein the zinc soaking liquid is prepared by dissolving sodium hydroxide in water, adding zinc oxide, heating the mixture until the mixture is entirely dissolved, dissolving ferric trichloride and sodium potassium tartrate tetrahydrate in the water, and adding the water and uniformly mixing after mixing; the copper pre-plating liquid is prepared by dissolving sodium cyanide in the water, adding cuprous cyanide, and adding the water to uniformly mix; and the copper plating liquid is prepared by respectively adding water to dissolve and mix copper pyrophosphate, potassium pyrophosphate and disodium hydrogen phosphate, dissolving amine triacetate with a sodium hydroxide solution, and adding the water after the both are mixed; removing oil of the aluminum conductive body, bleaching the aluminum conductive body, soaking the aluminum conductive body into the zinc soaking liquid for zinc soaking twice, placing the aluminum conductive body in the copper pre-plating liquid for copper pre-plating, washing the aluminum conductive body, and then arranging the aluminum conductive body in the copper plating liquid for copper plating so as to achieve a requested thickness. The surface treatment method provided by the invention is simple, is easy to operate and use, is good in effect, and is safe and environment-friendly. Therefore, the properties of a lead wire are improved.

Description

technical field [0001] The invention relates to electricity, in particular to a surface treatment method for increasing the conductivity of an aluminum conductor used in a switchgear. Background technique [0002] In the distribution circuit of the switch cabinet, the connecting wires use aluminum conductors in many places, because the conductivity of aluminum is not as good as that of copper, and in the distribution circuit of the switch cabinet, the conductivity of the connecting wires is required to be high to increase the conductivity of the connecting wires. capacity and reduce power consumption in power transmission. And the cost of copper material is high and lacks. Therefore, in order to ensure the conductive effect of the connecting wires in the switch cabinet power distribution circuit, save energy and reduce costs, the surface of the switch cabinet aluminum conductor is required to be treated in the switch cabinet power distribution circuit. [0003] There are t...

Problems solved by technology

The other is chemical (such as pickling, alkali cleaning) treatment to remove oil and dirt, and then install it directly on the switch cabinet for use, but due to the problems in the treatment method, the effect is not satisfactory, so how to effectively deal with aluminum conductors , so far there is no surface treatment method to increase the conductivity of aluminum conductors
