Belonging to the technical field of graphite / metal phthalocyanine, the invention relates to a method for preparing a graphene / metal phthalocyanine compound composite material through electrostatic assembly. The method includes: combining graphene oxide with PDDA through electrostatic adsorption, and reducing the graphene oxide into graphene with a reducing agent so as to obtain a GR / PDDA composite material, which is then further combined with a metal phthalocyanine compound by electrostatic adsorption, thus finally obtaining the graphene / metal phthalocyanine compound composite material. In the invention, strong electrostatic adsorption exists between the graphene and the PDDA, and between the PDDA and a metal phthalocyanine derivative, self-agglomeration of graphene can be prevented, so that the metal phthalocyanine derivative can be evenly attached to the graphene surface.

The invention discloses an agricultural greenhouse composite film and a preparation method thereof, comprising the following steps: S01, preparing an outer reinforcing layer includes: preparing a mixed material for the outer reinforcing layer, and casting: putting the mixed material of the outer reinforcing layer into a reaction kettle, polymerizing Heating and melting after the reaction, the extruder extrudes the melt from the chilled roll to form a cast sheet, stretching: stretching the cast sheet to obtain an outer reinforcement layer, S02, preparing the anti-fog dripping layer includes: preparing the anti-fog flow The drop layer mixture includes the inner layer mixture, the middle layer mixture and the outer layer mixture. Blow molding: add the above three-layer mixture to the hopper of the three-layer co-extrusion blown film machine, extrude from the three-layer co-extrusion die, and the cooling fan Inflate and cool to make the anti-fog dripping layer, S03, use polyurethane adhesive to bond the outer layer of the outer reinforcement layer and the anti-fog dripping layer through a bonding machine to make a composite film for agricultural greenhouses, solve The problems of traditional agricultural membranes such as limited thermal insulation performance, weak strength, easy aging, and poor light transmission have been overcome.

The invention relates to a residual heat boiler of a steel ball dedusting type ore heat furnace. The residual heat boiler at least comprises a boiler heated surface, a seal boiler flue gas passage, a furnace top and a furnace bottom ash hopper, wherein the boiler heated surface comprises coil pipe groups; and the seal boiler flue gas passage is formed at the periphery of the boiler heated surface. The residual heat boiler is characterized in that the furnace top is provided with a steel ball spreading device, a steel ball separating and collecting device is arranged under the furnace bottom ash hopper; a circulating type steel ball mechanical transporting device is arranged between the steel ball spreading device and the steel ball separating and collecting device; the circulating type steel ball mechanical transporting device comprises at least one drive wheel, at least three driven wheels, a double-row chain, a horizontal guide rail, a steel ball transporting hopper and a mechanicaldischarge blocking wheel; the at least one drive wheel and the at least three driven wheels are fixed on a boiler frame, and the steel ball transporting hopper is hung on the double-row chain surrounded between the drive wheels and the driven wheels; and the furnace top is provided with the mechanical discharge blocking wheel capable of turning over the steel ball transporting hopper. The invention has simple mechanism, recycled steel ball, mechanical automation running, low investment and running cost and favorable dedusting effect, and the like, can effectively remove and collect accumulated ash and sticking dust on the residual heat boiler heated surface of the ore heat furnace and greatly develops the energy-conservation and emission-reduction technology of the ore heat furnace smelting industry.
