The hardware fastener can make full contact with a high-oxidizing-property chemical solution, a black iron oxide film which is attractive and compact and has an anti-rust effect is formed on the surface of the hardware fastener, the anti-corrosion performance of the fastener is improved, the function of high anti-rust treatment efficiency can be achieved, and the practicability of the device is improved.

The utility model relates to the technical field of material treatment equipment, and discloses a pretreatment device for wet production of iron oxide black, which comprises a bottom plate, an upper surface of the bottom plate is fixedly connected with a crushing box; and the limiting rods are movably connected to the left side and the right side of the upper surface of the smashing box in a sleeving mode, and the bottom ends of the limiting rods penetrate through the smashing box, extend into the smashing box and are fixedly connected with pressing plates. By arranging the limiting rod, the pressing plate, the gear, the toothed plate and the smashing wheel, when the first motor operates, the circular shaft and the gear start to rotate, due to the fact that the gear is meshed with the toothed plate, rotation of the gear drives the toothed plate, and the toothed plate and the pressing plate start to move downwards under limiting of the limiting rod; and finally, the pressing plate can abut against the large-size ore in the crushing box, so that the ore makes contact with the two crushing wheels all the time, and at the moment, the large-size ore can be crushed through rotation of the two crushing wheels.

The invention discloses a method for manufacturing a new sound-absorbing and noise-reducing material by using polyimide foam scraps, cutting and processing the scraps generated in the process of polyimide foam production into particles of different sizes, drying red iron oxide or black iron oxide or titanium dioxide as inorganic additive, and then using each component in parts by weight, putting the inorganic additive into the mixer, and then putting the polyimide foam particles of different sizes into the mixer to mix, injecting the curing agent into the mixer to continue mixing, and finally adding the catalyst into the mixer to continue mixing, putting the mixed material into the mold evenly to form the film, leaving it for 10 hours, opening the mold, taking out the product, removing the burrs, and cutting the product according to customer needs, and packing it in a carton for storage.
