Metal grid flexible conductive film and manufacturing method thereof
ActiveCN113391733AGuaranteed continuityPlay a protective effectInput/output processes for data processingPtru catalystCopper plating
The invention discloses a metal grid flexible conductive film and a manufacturing method thereof, the metal grid flexible conductive film comprises a base material, a catalyst layer is arranged on the surface of the base material, a protective layer is arranged on one side, away from the base material, of the catalyst layer, and a metal grid is arranged between the catalyst layer and the protective layer. The circuit pattern is formed through exposure and development of the photoresist, the line width of the metal grid and the distance between the adjacent circuits can be accurately controlled, and the effects of good touch control and vision are achieved; the thickness of the metal layer is accurately controlled by using a chemical copper plating process, so that the conductive film product is light and thin; the metal layer is generated in the groove in the photoresist layer, so that the risk that the copper circuit is scratched by the transmission roller in the roll-to-roll production process can be effectively reduced, the conductivity of the metal circuit is ensured, the protective layer formed by coating the outermost layer plays a role in protecting the whole circuit, and the stable product performance is ensured.

Low-rank coal anaerobic upgrading, grading and grading system
PendingCN111961487AReduce manufacturing costReduce consumptionSpecial form destructive distillationHeat carrierThermodynamics
The invention discloses a low-rank coal anaerobic upgrading, grading and grading system, and belongs to the technical field of raw coke oven gas production. The technical problem to be solved is to provide the low-rank coal oxygen-free upgrading, grading and grading system, low-rank coal is subjected to oxygen-free cracking to generate raw coke oven gas, the production cost is saved, and the production quality is improved. The adopted technical scheme is as follows: the system comprises a heat exchange furnace, a cooler, a rotary kiln, a raw coal preheater, a cyclone dust collector, a main fan, a desulfurizing tower, a raw coal conveyor and a carrier output fan. The heat of the high-temperature combustion gas is transferred to the raw coke oven gas carrier in a heat conduction manner; theraw coke oven gas carrier enters the rotary kiln in a closed oxygen-free environment and is subjected to cracking reaction with the low-rank coal to generate a large amount of raw coke oven gas, and the heat carrier is the same product and is doped with few impurities, so that the influence of burning coal impurities and air impurities on the product is avoided, the low-rank coal on the market isconsumed, and enterprise benefits are formed.
