The invention relates to the technical field of oil and gas well reservoir transformation, and provides a permeability-enhancing surfactant for shale gas fracturing and a preparation method thereof, and the permeability-enhancing surfactant is synthesized from 3, 4-difluoromaleic anhydride, alkyl polyoxyethylene polyoxypropylene alcohol and sodium isethionate. According to the permeability-enhancing surfactant for shale gas fracturing, fluorine atoms in aliphatic fluoride enable the permeability-enhancing surfactant to have very good low surface tension and wettability, and meanwhile, epoxy groups are introduced into gemini surfactant molecules, so that the wetting effect can be improved, and the permeability-enhancing surfactant is environmentally friendly. Therefore, aiming at the characteristics of a shale reservoir, from the aspects of excellent surface performance, cost reduction, environmental friendliness and the like, the permeability-enhancing surfactant for shale gas fracturing, provided by the invention, has a relatively good practical application value.

The application discloses a kind of ZIF-8 nanoparticle loaded cellulose barrier membrane and preparation method thereof, comprising the following steps: (1) TOCNF suspension gel is diluted into TOCNF suspension by deionized water, to obtain nanocellulose suspension solution A;(2) zinc nitrate hexahydrate is added in solution A to obtain solution B;(3) polyvinylpyrrolidone is added in solution B to obtain solution C;(4) 2-methylimidazole is added in solution C to obtain solution D;(5) solution D is placed in mold by vacuum filtration device to form a wet film, the wet film is removed, and the wet film is clamped between two pieces of acrylic plate, dried in vacuum drying oven, to obtain ZIF-8 nanoparticle loaded cellulose barrier membrane.The application selects TOCNF as the template for ZIF-8 growth, TOCNF as the template for ZIF-8 in-situ growth, which can effectively prevent them from forming aggregates, and load ZIF-8 nanoparticles through in-situ + non-in-situ method to improve the hydrophobicity, thermal stability and ultraviolet shielding property of TOCNF membrane.

This invention provides a roll-over monitoring and control system and method for rolled glass rollers, relating to the field of glass manufacturing technology. It includes: multiple temperature monitoring devices arranged along the length of the rolled glass rollers for real-time monitoring of the surface temperature of various areas on the rollers; and a controller that, when any surface temperature exceeds a first preset threshold, controls the roller motor to slow down, increases the cooling water flow of the roller liquid cooling device, and activates the purging device, while simultaneously issuing a roll-over alarm to on-site personnel to remind them to conduct on-site inspections and manual intervention. The beneficial effect is that the handling procedure is initiated at the nascent stage of the roll-over phenomenon, accurately controlling the "golden 5-second" window for fault handling, reserving crucial time for on-site personnel to arrive and implement subsequent manual intervention, thus suppressing the rapid spread and expansion of the roll-over defect from the source, and completely breaking the passive predicament of traditional handling schemes where the fault has already developed to a moderate stage by the time it is discovered.

The core material has excellent flame retardancy, antibacterial property and mechanical property.

The utility model discloses a kind of coating die and coating device, belong to battery processing equipment field, the coating die includes upper die and lower die, upper die and lower die between being equipped with the cavity for slurry flow, further include ultrasonic wave subassembly, one end of ultrasonic wave subassembly is located in cavity, the surface of cavity is sprayed with super-hydrophobic coating, for preventing slurry adhesion in cavity. The present application not only can avoid the particle in slurry adhesion in cavity, but also can prevent the particle in slurry from settling under the action of gravity, to reduce the risk of plugging.

The application discloses a target material binding combination promoting method and belongs to the technical field of target materials. The target material binding combination promoting method comprises the following steps: (1) taking a stainless steel pipe as an inner lining pipe, cleaning the inner lining pipe, and performing sand blasting treatment on the stainless steel pipe to form a sand blasting layer; (2) spraying alloy wires onto the sand blasting layer by adopting an electric arc spraying method to form an alloy layer; (3) performing plasma treatment on the stainless steel pipe; and (4) heating the stainless steel pipe, coating solder on the alloy layer to form a solder layer, and performing ultrasonic treatment. The sand blasting layer, the alloy layer and the solder layer are formed on the stainless steel pipe, and the plasma treatment and the ultrasonic treatment are performed on the stainless steel pipe, so that the binding between the inner lining pipe and the target material base body is effectively improved, and the binding combination rate of the target material is effectively improved.
