The invention discloses a preparation method and application of banana fiber chitosancomplex hydrogel. The preparation method comprises the following steps: firstly, after banana fibers are cut, performing acid pickling, secondary soda boiling and washing on the banana fibers, so as to obtainbanana cellulose; then, dissolving the banana cellulose into ionic liquid, so as to obtain banana cellulose solution; meanwhile, dissolving chitosan powder into polyacrylic acid solution, so as to obtain chitosan solution; adding thechitosan solution into the banana cellulose solution for mixing and dissolving and accelerating effective crosslinking with a crosslinking agent in temperature rise, so as to obtain banana fiber chitosancomplex hydrogel solution; finally, washing, so as to obtain the banana fiber chitosancomplex hydrogel. The banana fiber chitosancomplex hydrogel prepared by the invention is strong in adsorption capacity for heavy metal ions, high in adsorption speed and good in biological compatibility and can be applied to treatment of heavy metal pollution in the environment, so that the environment improvement efficiency is improved favorably, and the banana fibers are fully utilized, therefore, a win-win effect is realized.

The invention relates to a hot rolled wire rod for ultra-low carbon steel fibers and a production method of the hot rolled wire rod. The wire rod comprises the chemical components of, by mass, less than or equal to 0.010% of C, less than or equal to 0.03% of Si, less than or equal to 0.20% of Mn, less than or equal to 0.020% of P, less than or equal to 0.020% of S, greater than or equal to 0.02% of Alt, 0.05-0.12% of Ti and the balance iron and inevitable impurities. The production method comprises the procedures of continuous casting, cogging, heating, rolling, spinning and cooling. By adding the Ti elements to ultra-low carbon steel, through low-temperature rolling, uniform ferrite and pearlite structures are generated, effective combination of strength and plasticity is achieved, thus, the tensile strength of the wire rod with the specification being phi 7.0 mm is 310-360 MPa, the percentage elongation after fracture is greater than or equal to 50.0%, 1300-MPa-class steel fibers are allowed to be produced through the wire rod with the large specification under the condition that existing equipment of downstream customers is not changed, the purchase cost is lowered, and the downstream customer selectivity is increased.

The system and method can improve the electricity charge incomes of a super power plant, can reduce insufficient generating capacity examinations caused by power plant self reasons, and can reduce the insufficient generating capacity compensations caused by power plant system reasons, thus providing multi-party win-win effects.

The invention belongs to the technical field of marine energy utilization, and specifically relates to a floating wind turbine and a control method for an oscillating water column wave energy device, including a floating platform, a tower, a fan, an oscillating water column wave energy device, and a control module. The type platform includes n buoys evenly distributed around the center of the tower, an air chamber is arranged in the buoy, the bottom of the air chamber has an air inlet, and the top is provided with an air outlet. The number of the oscillating water column wave energy devices is the same as that of the buoy. Fitted and installed in the air outlets of the n buoys respectively, the oscillating water column wave energy device includes an air turbine, a mechanical transmission module and a generator module. The invention improves the utilization rate of deep-sea renewable energy, reduces the cost of power generation, combines the existing mature offshore wind energy technology, promotes the commercial application of wave energy devices, and realizes the win-win effect of comprehensive management of multiple energy sources.

The invention provides a chitosan and seaweed fertilizer joint production method and belongs to the technical field of aquatic product processing. In the chitosan production process, potassium hydroxide replaces sodium hydroxide and then potassium hydroxide waste liquor is used as a digestant for seaweed fertilizer production; hydrochloric acid is replaced by nitric acid and nitric acid waste liquor replaces part of phosphoric acid to be used as a neutralizer for a seaweed digestive liquid. The traditional thinking is changed, waste alkali liquor is utilized instead of being treated, the waste is turned into wealth, and treatment of the waste alkali liquor in chitosan production is avoided. Meanwhile, the potassium hydroxide waste liquor contains a large quantity of organic matters such as animal protein and the like, and the nitric acid waste liquor contains abundant calcium and microelements, so that produced seaweed fertilizer is rich in nutrition and better in fertilizer efficiency. Two production technologies are combined, the production cost of chitosan and the seaweed fertilizer is reduced, the quality of the seaweed fertilizer is improved, and the win-win effect is realized.

The invention relates to a calcination-free desulfurized gypsum walling plastering dry-mixed mortar, belonging to the technical field of construction materials. In order to solve the technical problems of overhigh raw material cost, and poor binding property, poor thermal insulation property and low strength after being applied to walling in the mortar in the prior art, the invention provides a calcination-free desulfurized gypsum walling plastering dry-mixed mortar which is mainly prepared from 20-40 parts of calcination-free desulfurized gypsum, 30-60 parts of aggregate, 0.05-0.2 part of water retention agent and 8-15 parts of gypsum modifying material.
