Problems solved by technology

Among them, the density of metal powder is high, and a large volume fraction is required to form a conductive path. The surface layer is easily oxidized, which will reduce or even lose electrical conductivity, and has poor corrosion resistance, thereby affecting other properties of the coating. Therefore, the application of metal powder as a conductive filler is subject to certain restrictions. Restrictions; antistatic agents have poor temperature resistance, water resistance, oil resistance, corrosion resistance, durability, and unstable antistatic performance; early antistatic coatings generally use carbon-based materials as conductive fillers, and black conductive graphite and carbon black have poor dispersion. The color of the product is black, and it is not easy to adjust to other lighter colors; with the development of science and technology, new conductive fillers such as semiconductor metal oxides and nano-conductive powders have gradually appeared, and have been applied in antistatic coatings. These materials are light in color , easy to color, enrich the color system of antistatic coatings, but when this kind of material is used alone, the addition amount is large, and the dispersion stability is poor, which will affect the performance of the coating and its coating, so it is generally used in conjunction with carbon-based materials

Description

technical field [0001] The invention belongs to the field of distribution box preparation, and in particular relates to a closed low-voltage distribution box. Background technique [0002] The distribution box is a large number of parameters in the data, and generally constitutes a low-voltage distribution box. According to the electrical wiring, it is required to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen width to form a low-voltage distribution box. box. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. The distribution box is used to distribute electric energy reasonably and facilitate the opening and closing operation of the circuit. It has a high level of safety protection and can intuitively display the conduction state of the circuit. [0003] Static electricity is a phenomenon of charge accumulation ...
