The invention discloses an industrial abrasive band based on chopped linen fibers and aims to solve the technical problems that a base material of the conventional abrasive band does not have a grinding function and is poor in mechanical performance, elasticity modulus is difficultly improved greatly and the like. The industrial abrasive band comprises a base material, wherein the base material is subjected to soaking and scraping treatment or soaked with glue which contains the chopped linen fibers or is added with sand; a layer or a plurality of layers of glue which contains the chopped linen fibers or is added with the sand is formed on one surface, namely the front side or the back side of a treated fabric base through blade coating according to requirements, then a primer containing the glue which contains the chopped linen fibers or is added with the sand is coated, then sand is planted on the primer, and the primer is coated with composite glue, wherein the composite glue can be glue which contains the chopped linen fibers or is added with relative fine grained sand. According to the industrial abrasive band, a messy structure of the chopped linen fibers is adopted, so that the shock resistance of the glue layers is improved; simultaneously, the chopped linen fibers can be synchronously consumed and has certain polishing and grinding performance; and due to certain hardness and brittleness of linen fiber, the industrial abrasive band has grinding capability, the performance is improved, and the using cost is reduced.

The invention relates to a manufacturing method of polyvinyl alcohol concave-convex sponge. The polyvinyl alcohol concave-convex sponge comprises a polyvinyl alcohol concave-convex sponge body, a PVC soft glue film, a bottom glue layer, a composite glue layer and abrasive materials. Dot patterns are bestrewed on the front face of the polyvinyl alcohol concave-convex sponge body. The dot patterns are composed of a plurality of semispherical salient points arranged uniformly. Gaps between the adjacent salient points are mutually connected to constitute a communicating groove. The PVC soft glue film is formed on the back face of the polyvinyl alcohol concave-convex sponge body. The front face of the polyvinyl alcohol concave-convex sponge body is coated with the bottom glue layer. The upper surface of the bottom glue layer is coated with the composite glue layer. The lower ends of the abrasive materials are embedded into the bottom glue layer, and the upper ends of the abrasive materials protrude out of the upper surface of the composite glue layer. The concave portions of the position, corresponding to the communicating groove, of the surface of an abrasive belt communicate with one another to constitute a chip removal groove. The manufacturing method of the polyvinyl alcohol concave-convex sponge not only achieves the properties of blockage preventing and elastic grinding but also has the advantages that the process is simple, equipment investment is low, cost is low, abrasion resistance is achieved, service life is long, and toxicity is avoided.

The invention discloses a seal valve. The seal valve comprises a valve body, an air inlet, an air outlet, a valve element opening and closing mechanism, a load control mechanism, a valve element rotating mechanism, a valve element and a valve rod, wherein the air inlet and the air outlet are formed in the valve body; a valve seat is arranged at the air inlet or the air outlet and is in contact with the valve element; the valve element is connected with the valve rod; the valve rod penetrates the valve body and is connected with the valve element rotating mechanism; the valve element rotating mechanism is connected with the valve element opening and closing mechanism through the load control mechanism; and rotary motion of the valve element rotating mechanism and linear motion of the valve element opening and closing mechanism are changed into relatively independent motions through the load control mechanism. According to the seal valve, the opening and closing force and the rotating, driving and grinding resistance are controlled by the load control mechanism, so that the seal valve has reliable leakproofness.

The invention discloses a fixed-length cutting device for Chinese herbal medicine processing and with a grinding function. The fixed-length cutting device for Chinese herbal medicine processing and with the grinding function comprises a workbench, a cutting blade, flow guide plates, a first grinding roller and a second grinding roller. Fixing plates are welded at the front end and the rear end ofthe right side of the workbench, and a fixing shaft is installed at the bottom of a top plate. The cutting blade is installed inside a protective cover, and the flow guide plates are fixedly arrangedat the outer ends of the bottoms of the workbench and the fixing plates correspondingly. The top of the first grinding roller and the top of the second grinding roller are connected with scraping plates, and the front end of the first grinding roller and the front end of the second grinding roller are connected with a second motor and a third motor in a rotating mode through third rotating shafts.A material holding tank is installed below the first grinding roller and the second grinding roller. By the adoption of the fixed-length cutting device for Chinese herbal medicine processing and withthe grinding function, fixed-length cutting can be conducted on the length of Chinese herbal medicine in the cutting process, and the cut Chinese herbal medicine is collected advantageously, and canalso be further ground.

The invention provides a biological preparation method for a carbon-silicon composite. The biological preparation method comprises the following steps: subjecting raw materials for a chicken feed and a silicon-containing material to mixing and granulation; feeding chicken flocks with the obtained silicon-containing chicken feed, allowing silicon-containing chicken feed to be fully mixed in the gizzards of chickens through digestion and allowing an organic carbon-source compound to coat the silicon-containing material in advance; allowing undigestable micro powder of the silicon-containing material and an undigested organic carbon-source compound to be discharged out in the form of chicken manure, collecting the silicon-containing chicken manure and carrying out drying and homogenization; and subjecting the homogenized silicon-containing chicken manure to high-temperature carbonization in an inert atmosphere so as to obtain the carbon-silicon composite. According to the invention, the gizzards of chickens, a biological stirrer, are made full use of for preparation of a precursor of the carbon-silicon composite, so the problem of pollution caused by the chicken manure is overcome, and the added value of the chicken manure is increased.
