The utility model relates to a double-stage electrostatic oil fume treatment unit with fresh air heating and oil stain self-cleaning functions, belonging to the field of high-voltage electrostatic purification of oil fume and the field of fresh air heating. The utility model is to solve the problems of low removal efficiency of oil fume particles caused by the phenomenon of "counter electric field" when high-voltage electrostatic technology purifies oil fume, poor cleaning effect of conventional cleaning measures, high corona voltage, easy air breakdown to form sparks, high risk of fire, and high energy consumption of heating fresh air in winter. The utility model includes an oil fume collecting device, a charging mixing section, a first-stage oil fume treatment section, a second-stage oil fume treatment section, oil fume pipeline components, and fresh air pipeline components. The oil fume collecting device is installed at the inlet end of the oil fume pipeline components. The charging mixing section, the first-stage oil fume treatment section, and the second-stage oil fume treatment section are connected in series in the oil fume pipeline components in the order of the oil fume flow direction. The fresh air pipeline components are installed on the first-stage oil fume treatment section and the second-stage oil fume treatment section. The utility model is used as a device for treating indoor oil fume and preheating indoor fresh air.

The application belongs to the technical field of ink, and particularly relates to a preparation method of high-adhesion conductive ink based on a network, which comprises the following steps: adding a dispersing agent, a defoaming agent, a pigment and water-based polyurethane into water, fully stirring to form a mixed solution; adding a conductive material and a fibrous filler into the mixed solution, rapidly stirring for 20-30 min, then adding a leveling agent and an anti-settling agent, and constant-temperature stirring to obtain the high-adhesion conductive ink. The application solves the problems of viscosity limitation and agglomeration of existing conductive fillers, utilizes the porous structure of polyvinyl alcohol polycondensate and the conductive modified fibrous filler to form a multi-dimensional network of porous conductive particles and conductive fibers, greatly improves the conductive network, and cooperates with the high adhesion of polydopamine and the high activity of polyurethane, so that the adhesion of the ink is effectively improved.

The application discloses a boron nitride composite powder for epoxy pouring sealant and a preparation method thereof, and belongs to the technical field of electronic packaging materials and preparation thereof. The application solves the problem that the rheological behavior and multifunctional performance of the existing epoxy resin pouring sealant cannot be simultaneously compatible at high filler content. In the application, thermoplastic polyurethane (TPU) is used as an adhesive, h-BN layers are assembled into spherical hierarchical particles BN@TPU, and the BN@TPU is added to an epoxy system as a filler, so that the interface energy between the filler and the epoxy matrix is significantly reduced, excellent process flowability and operating viscosity can be maintained at high filler content, and the heat conduction performance is not lost. Experimental results show that the initial viscosity of the pouring sealant with a BN@TPU addition amount of 30wt% is obviously lower than that of a pure BN addition system with the same addition amount, the tensile strength is also significantly improved, and the processing window range is significantly widened.
