Chimney for unsaturated resin acid waste gas treatment
ActiveCN224215868UOptimize emissions statusImprove processing efficiencyChimneysWaste heat treatmentResin acidMechanical engineering
The utility model relates to the technical field of waste gas treatment, and discloses a chimney for unsaturated polyester resin acid waste gas treatment, which comprises a chimney body, an exhaust pipe is fixedly connected to the outer wall of the chimney body, a shell is fixedly connected to the outer wall of the exhaust pipe, an adjusting assembly is arranged in the shell, and a driving assembly is arranged at the bottom of the shell. The adjusting assembly comprises two guide rods, the guide rods are fixedly connected into the shell, the outer walls of the guide rods are slidably connected with two sliding blocks, a baffle is fixedly connected between the outer walls of the two sliding blocks, the outer walls of the guide rods are sleeved with springs, the driving assembly comprises a shell, and the shell is fixedly connected to the bottom of the shell. According to the utility model, the flow and the flow velocity of waste gas are intelligently adjusted through the cooperative work of the adjusting assembly and the driving assembly. When the temperature of waste gas changes, the volume of paraffin in the shell changes, the baffle is driven by the connecting rod to slide on the guide rod, and therefore the waste gas circulation section in the exhaust pipe is adjusted.

Modified plastic composite master batch and production process thereof
The invention relates to the technical field of materials, and discloses a modified plastic composite master batch and a production process thereof.The modified plastic composite master batch is prepared from ethylene propylene diene monomer and chlorinated polyethylene as main raw materials and modified additives as additives through mixing and extrusion granulation processes. Wherein the modified additive is prepared by modifying the surface of pyrophyllite with a macromolecular modifier, and due to the existence of the macromolecular modifier, the interface affinity of the pyrophyllite and the ethylene propylene diene monomer can be improved, so that the pyrophyllite can give full play to the reinforcing effect of the pyrophyllite as an inorganic additive, and the mechanical strength of the plastic is improved. Besides, the macromolecular modifier can promote rapid formation of an expanded carbon layer structure on the surface of the material during combustion to effectively prevent heat and oxygen, and meanwhile, pyrophyllite can form a layer of stable and high-temperature-resistant ceramic barrier during combustion to cooperate with a carbon layer, so that the flame retardant property of the material is greatly enhanced.

Fabricated steel structure fireproof connection node structure
The utility model discloses an assembly type steel structure fireproof connection node structure, and relates to the technical field of steel structure connection nodes, the assembly type steel structure fireproof connection node structure comprises four steel structures, each steel structure is integrated with a fireproof mechanism for fire prevention, and the steel structures are connected with the fireproof mechanism. The fireproof mechanism comprises triangular connecting pieces, side expansion fireproof gaskets and heat insulation cotton, and supporting steel is fixedly installed at the ends of the three sides of each triangular connecting piece. The heat insulation cotton, the side expansion fireproof gaskets and the end expansion fireproof gaskets are arranged on the triangular connecting piece and matched with one another, the heat insulation cotton can achieve a good heat insulation effect, the rising speed of the node temperature is delayed, and therefore the fire resistance of the node is improved, and when the fire behavior is serious, the heat insulation effect is good. The side expansion fireproof gaskets and the end expansion fireproof gaskets can expand rapidly to form a thick foam-shaped heat insulation layer to prevent fire from spreading.
