The invention relates to a fireproof rolling shutter door with the good fireproof property and the anti-deformation capacity. The fireproof rolling shutter door comprises a box body, four guiding rails, two curtain boards and a control box, and further comprises a cooling mechanism, two bases and two clearing mechanisms; and each clearing mechanism comprises a moving assembly, a clearing brush anda guiding assembly. According to the fireproof rolling shutter door with the good fireproof property and the anti-deformation capacity, the leakproofness of the fireproof rolling shutter door is improved through the curtain boards and the bases, the capacity of the fireproof rolling shutter door to block fire spreading is further enhanced, and thus the fireproof property of the fireproof rollingshutter door is improved; meanwhile, through the clearing mechanisms, first grooves of the bases can be subjected to dust clearing work, and the situation that the matching degree of the first groovesand the curtain boards is affected by sundries accumulated in the bases and consequently the fireproof property is reduced is avoided; and the curtain boards are cooled through the cooling mechanism,so that the situation that the curtain boards are heated to be bent and deformed, and consequently the service life of the curtain boards is shortened is avoided, and accordingly the service life ofthe fireproof rolling shutter door is prolonged.

The invention belongs to the technical field of thin poplar sheet processing, and specifically relates to a method for improving the toughness of a thin fast growing poplar sheet. The method comprisesfollowing steps: processing a thin fast growing poplar sheet by an ethanol solution of sugar alcohol to obtain a preprocessed sheet, processing the preprocessed sheet by a processing agent, refrigerating the sheet, drying the sheet in a drying kiln, and preparing a finished product. Compared with the prior art, the method has the advantages that poplar wood is preprocessed by an ethanol solutionof sugar alcohol at a proper temperature, the structures of cells in the polar sheets are changed; processed poplar sheets will not be cracked in the drying kiln during the drying process; after the poplar sheets are processed by the processing agent, refrigerated, and dried in the drying kiln, the fibers in the wood are redistributed and combined, the fibers become uniform and are resistant to deformation; wood splinters will not be generated during the cutting and planning process, the stability and toughness of obtained poplar sheets are improved, and the application range is enlarged.

The healing rate is high, meets the relevant requirements of the national standard, meets the needs of daily life and medical treatment for wound liquid dressings, and has good application prospects. The preparation method of the liquid dressing of the present invention has simple operation and mild process conditions, and is suitable for industrialized large-scale production.

The invention discloses a compliant skin energy supply device which is mainly formed from, from bottom to top, a flexible substrate layer, a substrate electrode layer, and an energy patch composed ofa perfluorosulfonic acid polymer thin film layer. A laccase molecule layer and a platinum nano-particle layer are formed, in a cured manner, between the substrate electrode layer and the perfluorosulfonic acid polymer thin film layer, thus forming a positive electrode of a primary battery after curing; a glucose oxidase molecule layer, a glucose molecule layer and a platinum nano-particle layer are formed, in a cured manner, between the substrate electrode layer and the perfluorosulfonic acid polymer thin film layer, thus forming a negative electrode of a primary battery after curing. The compliant skin energy supply device is flexible and replaceable, has high energy transmission efficiency and is green and environment-friendly, wherein energy is sourced from a redox reduction of the glucose at the negative electrode and oxygen at the positive electrode.

The invention relates to a fireproof rolling shutter door with the good fireproof property and the anti-deformation capacity. The fireproof rolling shutter door comprises a box body, four guiding rails, two curtain boards and a control box, and further comprises a cooling mechanism, two bases and two clearing mechanisms; and each clearing mechanism comprises a moving assembly, a clearing brush anda guiding assembly.
