The Zhengzhou Abrasives Grinding Research Institute has recently obtained six patents, including “Centrifugal Hot Pressing Sintering Deviceâ€, “Powder Material Centrifugal Pressing Deviceâ€, “Vacuum Sintering Press Vacuum Chamber†and “Combined Grinding Pageâ€. The wheel has four utility model patents and two design patents of “sintering press (A)†and “sintering press (B)â€.
Among them, the "vacuum sintering press vacuum chamber" maintains the advantages of a simple and simple circular vacuum chamber structure, a simple cooling system and a vacuum sealing structure, and reliable performance. When sintering at low temperature, the door can be exhausted to reduce the pollution of the vacuum system by the flue gas. The workpiece can be taken and removed from the door, making the operation more convenient and time-saving. The product and sintering press have now produced more than 110 units, with a sales income of more than 6 million yuan. The “combined grinding wheel†is composed of a plurality of chuck wheel wheels. When the end faces of the adjacent page wheels are fastened, the splicing of the end faces forms a staggered structure, so that the joints on the wheel surface of the combined grinding wheel do not appear. The complete annular shape overcomes the shortcomings of conventional straight-line grinding marks when grinding with ordinary grinding wheels. Since the product was put into the market, it has been welcomed and praised by users. The product has achieved sales of more than 1.5 million yuan.
In addition, the "metal bond super hard material grinding wheel centrifugal hot pressing sintering method and device" has applied for invention patents and entered the substantive examination stage, and is expected to be authorized in recent days.

After the infection of the new coronavirus, the human nose, throat, hypopharynx, etc. will be "concurrently carried out". By collecting samples such as sputum of the nose, throat, and throat for human virus detection and testing, it can be determined whether the new coronavirus is worn.
