A multi-layer fabric loading fixture for loading fabric onto a paper machine. The loading fixture includes a first portion (400) with a rigid support member (410) and a plurality of spaced holes (420) across its width, the first portion being connected to an end of the fabric in the cross-machine direction. The first layer (430) is formed of cords which are sequentially threaded through the holes to form a self-adjusting loop. The second rope is sequentially threaded through the loops of the first layer to form the self-adjusting loops of the second layer (440). Pull rings (450) gather the loops of the second layer and are used to draw the fabric to the paper machine.

The invention relates to micro hanging type drying equipment in the field of washing and drying. The micro hanging type drying equipment comprises a hanging body, wherein a cavity is formed in the body; heating ventilation equipment capable of forming drying airflow is arranged in the cavity; at least one carrying part on which clothes are placed is arranged on the body; each carrying part is communicated with the cavity; and an air outlet through which the drying airflow blows to the clothes is formed in the carrying part. According to the arrangement, high-temperature drying airflow can be formed in the drying equipment and blows the clothes on the carrying parts through the air outlet, so that the drying airflow is in direct contact with the clothes, and the aim of drying the clothes is achieved. Meanwhile, the equipment disclosed by the invention is simple in structure, obvious in effect and suitable for popularization and application.

The invention discloses a fixing bracket for glass transportation, mainly relates to the field of construction equipment transportation. The fixing bracket for glass transportation comprises a main bracket body, a guide rail mechanism, a glass supporting mechanism, a limiting assembly and a buffering piece. The glass supporting mechanism achieves L-shaped extension adjustment by the bidirectionalguide rail mechanism, and achieves fixing and limiting by the limiting assembly; and the buffering piece achieves rigid shock absorption of glass. The fixing bracket has the beneficial effects of being capable of adapting to different conditions on site according to the glass with different sizes and characteristics to fix and transport the glass, significantly lowering transportation losses and improving resource utilization rate.

The invention provides a high-load platinum and nickel ordered intermetallic compound. The high-load platinum and nickel ordered intermetallic compound takes three-dimensional porous carbon gel as a carrier, and is prepared by a method comprising the following steps: evenly mixing graphene oxide-containing carbon carrier precursor dispersion liquid, a metal precursor solution containing a Pt precursor and an Ni precursor, a reducing agent and sodium citrate dehydrate; then, carrying out a hydrothermal reaction to generate high-load platinum and nickel disordered alloy evenly loaded in carbon gel; after that, carrying out heat treatment under the reducing atmosphere to form the high-load platinum and nickel ordered intermetallic compound evenly loaded in the carbon gel. Compared with the traditional high-load Pt / C catalyst, the catalyst provided by the invention relatively reduces the consumption of precious metal Pt; the activity of the catalyst is improved by using an intermetallic synergistic effect, the stability of the catalyst is improved by using high dispersion of ordered metal nanoparticles, and the high dispersion characteristic of the catalyst is still maintained after ordered heat treatment is carried out on the catalyst. The invention also discloses the preparation method of the high-load platinum and nickel ordered intermetallic compound. The invention also discloses use of the high-load platinum and nickel ordered intermetallic compound.

The invention discloses a method for preparing a polyurethane-modified organosilicon double-component room-curing elastomer adhesive, which comprises the following steps: (1) uniformly mixing hydroxypropyl-terminated silicone oil and glycerol, and dehydrating to obtain a hydroxyl-terminated (-OH) component; (2) reacting aromatic polyisocyanate, the hydroxyl-terminated (-OH) component and dibutyltin dilaurate to obtain a component A; (3) adding vapor-phase silica white, carbon black and talcum powder into the container filled with hydroxy silicone oil and dihydroxy polysiloxane, adding a catalyst, adding 3-aminopropyl triethoxy silane, finally adding a defoaming agent, uniformly mixing, and drying to obtain a component B; and (4) uniformly mixing the component A and component B in a mass ratio of 12:(23.5-24), and curing at room temperature for 4-5 hours. The elastomer adhesive prepared by the method has the advantages of favorable tear resistance, excellent high / low temperature resistance and excellent binding property. The preparation method is easy to operate and accessible in raw materials, and lowers the preparation cost.
