The invention relates to full-surface super-hydrophobic anti-freezing wood and a manufacturing method thereof. The preparation method comprises the following steps: partially removing lignin and hemicellulose to form spongy wood, injecting hydrophobic nanoparticles and perfluorosilane into the outer surface and internal pores of the spongy wood through an absorption-extrusion process, and finally,carrying out hot-pressing densification treatment to obtain the super-hydrophobic anti-freezing high-strength wood. The super-hydrophobic anti-freezing high-strength wood disclosed by the invention is densified full-surface hydrophobic wood; the densification means that the wooden pipeline and the porous wooden cell wall partially collapse, so that the thickness of the wood is reduced to 30-40% of the initial thickness, and the density is increased by 2.5-3 times; wherein the full-surface hydrophobicity refers to the synergistic hydrophobicity of the outer surface of the wood and the inner surface of the pore passage of the wood. According to the anti-freezing high-strength wood, the bending strength is improved by 2-4 times compared with logs made of the same material; after 10 times offreezing and thawing cycles and 50 times of freezing and thawing cycles respectively, the bending strength is kept at 80% or above and 50% or above respectively; and the dimensional stability is stillmaintained even after 50 times of freezing and thawing cycles.

A free-fall powder mixing gas atomization water-cooled quick-setting magnetic abrasive preparation equipment, including a double-nozzle atomization water cooling device (41), a screw powder mixer (17), a water-sealed dust removal device (42), and a gas station (44) .

A free-fall two-stage powder-mixing gas atomization water-cooled quick-setting magnetic abrasive preparation method is characterized in that: a two-stage free-fall nozzle is used, the first-stage nozzle is a low-pressure powder-mixing jet nozzle, and the second-stage nozzle is a high-pressure air flow nozzle. The low-pressure powder mixing jet nozzle is close to the top of the high-pressure air flow nozzle; by adjusting the water level of the cooling water in the atomization cooling chamber, the cooling speed of the mixed powder metal droplets is controlled, thereby forming a hard abrasive on the surface of the magnetic abrasive metal matrix. Distributed magnetic abrasives. The method solves the problems of full mixing of hard abrasives and molten metal liquid before atomization and waste of hard abrasives, control of the proportion of hard abrasives in magnetic abrasives, erosion wear of single-stage nozzles, hard abrasives in magnetic abrasives, etc. Problems such as the control of the depth of the superficial layer of the metal substrate, and at the same time greatly reduce the flying distance of the powder-mixed metal droplets, and reduce the overall height of the atomization chamber and equipment. The invention provides a new technical method for the preparation of high-performance magnetic abrasives.
