The present invention relates to the technical filed of wood processing, in particular to the method for strengthening the wood surface, the profiles and the solid wood flooring of the same. The density of the surface-strengthened solid wood profiles are 300˜580 Kg / m3, the reinforced surface is 1˜5 mm thick, the hardness of the paint film of the reinforced surface is 2H˜8H, the overall moisture content of the profiles are 6˜9%. The hardness of the paint film on the reinforced surface of the inventive solid wood profiles is higher, and the overall moisture content is stable, which is suitable for wider range of climate conditions.

The invention provides a solid polymer fuel cell whose operational stability over time has been enhanced. A reinforced solid polymer electrolyte composite membrane for a solid polymer fuel cell according to the present invention comprises two or more polymer electrolyte membranes and one or more layers of a sheet-like porous reinforcing member, wherein the polymer electrolyte membranes provide both the upper and lower surfaces of the composite membrane, and pores in the sheet-like porous reinforcing member are substantially filled with the electrolyte from the polymer electrolyte membranes, and wherein the sheet-like porous reinforcing member contains a peroxide decomposition catalyst.

The invention belongs to the technical field of wood function improvement and wood processing, and specifically discloses an integral reinforced solid wood profile and a manufacturing method thereof. The method comprises the following steps: under the condition of low moisture content (1-3%), the wood is subjected to integral compression treatment with low compression rate by adopting a heating and softening forming technology, so as to obtain an integral compressed material with uniform cross-sectional density. The method can effectively reduce the phenomenon of blasting and bubbling caused by excessive steam pressure inside the wood, greatly shorten the heat preservation time, and improve work efficiency. The overall compressed timber profile obtained by the method of the invention has good dimensional stability, is environmentally friendly and healthy, and can be used for manufacturing solid wood floors, solid wood furniture and as interior decoration materials.

The invention relates to a chemically reinforced solid-liquid separation method for a well drilling waste liquid, comprising the following steps of: mixing the well drilling waste liquid with clear water, regulating the solid content of the well drilling waste liquid to 5%-10%, and then carrying out capillary pumping for not more than 2500s; adding a destabilizing agent comprising 0.3%-0.5% of sulfuric acid or nitric acid, 0.4%-1.0% of polyaluminium silicate chloride and 0.2%-0.3% of polyferric sulfate; adding adsorbents comprising 1%-1.5% of quick lime and 0.5%-1% of calcium chloride; adding a flocculating agent comprising 0.005%-0.015% of cationic polyacrylamide, anionic polyacrylamide or amphoteric polyacrylamide; accomplishing solid-liquid separation by using a centrifugal machine and then respectively discharging separated solid phase and liquid phase, wherein the centrifugal factor of the centrifugal machine is 2000-2200g, the water content of discharged mud is not greater than 70%, the solid content of the discharged water is not greater than 0.5%, and the recovery rate of the solid phase is not less than 90%. The chemically reinforced solid-liquid separation method reduces the difficulty in subsequent advanced treatment on the well drilling waste liquid, thereby creating the favorable conditions for resource recycling of the liquid phase.
