The invention discloses a synthesis method of pyroxasulfone. The synthesis method comprises the following step: catalyzing # imgabs0 # by using oxidase as a catalyst to generate pyroxasulfone. According to the technical scheme, the thioether intermediate or the sulfoxide intermediate is oxidized by the oxidase to obtain the pyroxasulfone with higher conversion rate and yield, the synthesis method avoids the use of a strong oxidant and a toxic catalyst, and the potential safety hazard in the synthesis process of the pyroxasulfone is greatly reduced. The method provided by the invention has the advantages of stable process conditions, mild reaction conditions, simple operation and low pollution in the whole production process, and provides a new thought and method for artificially synthesizing the pyroxasulfone.

The present invention discloses a bell-shaped furnace for debinding and sintering and a method for using the bell-shaped furnace, which relates to the technical field of bell-shaped furnaces and includes a furnace body; it is characterized in that a thermal field control mechanism is provided on the furnace body, and the thermal field control mechanism includes: a first heating mechanism, which is provided on the furnace body and is used for high-temperature sintering; a second heating mechanism, which is provided on the furnace body and is used for low-temperature preheating and debinding; and a temperature detection mechanism. The present invention integrates the first heating mechanism and the second heating mechanism in the same bell-shaped furnace by providing a thermal field control mechanism, thereby achieving a seamless connection between low-temperature debinding and high-temperature sintering; this method omits the intermediate material transfer link, effectively avoiding the problem of material damage caused by transfer, while reducing the temperature loss during the transfer process, and significantly reducing energy consumption; this integrated design not only improves production efficiency, but also ensures the continuity and stability of the process.

This invention provides a supercritical fluid homogenization injection device, belonging to the field of supercritical fluid technology. The device includes a first barrel and a second barrel arranged at an angle. The first barrel is positioned above the second barrel, and the two are connected by a unidirectional conveying assembly. One end of the unidirectional conveying assembly is connected through to the middle of the second barrel, and the other end is connected through to one side of the first barrel. A foaming screw is installed inside the first barrel, and a supercritical fluid injection port is provided on its side wall. This invention solves the problem that traditional supercritical injection molding equipment struggles to achieve full fusion of supercritical fluid and raw materials, resulting in agglomeration or uneven distribution of supercritical fluid in the melt. This leads to density differences and fluctuations in mechanical properties in the molded product, severely affecting product quality stability. Simultaneously, it addresses the issue of foaming ratio.

This invention discloses a high-precision grinding system for the tip of a workpiece, belonging to the technical field of grinding systems. It includes an operating table with two symmetrical side frames fixedly connected to its top; a multi-dimensional clamping assembly positioned on the upper and lower sides of the operating table; a vision-sensing grinding positioning assembly positioned on top of the operating table; and a floating grinding head assembly positioned behind the vision-sensing grinding positioning assembly. The multi-dimensional clamping assembly provides stable clamping of the workpiece during grinding; the vision-sensing grinding positioning assembly achieves truly flexible intelligent manufacturing and compares the actual grinding effect with standard requirements, realizing integrated processing and inspection; the floating grinding head assembly effectively prevents impact force from being directly transmitted to the three-axis motion system and the workpiece surface.
