Embodiment 1
[0030] Such as figure 1 and figure 2 As shown, an auxiliary packing device for large-volume items includes a base 3, a fixed bracket 2 and a necking compression structure 1, the fixing bracket 2 is fixed above the base 3, and the necking compression structure 1 is installed on the fixing bracket 2 above; the necking compression structure 1 is a hollow cylinder or platform, the axis of the necking compression structure 1 is generally horizontally arranged, the opening on one side of the necking compression structure 1 is larger than the opening on the other side, and the necking compression The smaller opening end of the structure 1 is matched with the packing box; the inner wall of the shrinkage compression structure is coated with a layer of smooth anti-wear coating;
[0031] The coating of the coating is composed of the following components by weight: 7 parts of 100-200 mesh white corundum powder, 9 parts of gray calcium, 9 parts of heavy calcium powder, 10 parts of polyvi...
Embodiment 2
[0043] The coating of the coating is composed of the following components by weight: 10 parts of 100-200 mesh white corundum powder, 5 parts of ash calcium, 7 parts of heavy calcium powder, 20 parts of polyvinyl alcohol, 9 parts of emery, 15 parts of polyimide 2 parts, 2 parts of glass fiber, 55 parts of water-based polyurethane, 8 parts of zinc oxide, 30 parts of deionized water.
[0044] The applied coating has smooth surface, hard texture and good wear resistance.
Embodiment 3
[0046] The coating of the coating is composed of the following components by weight: 7 parts of 100-200 mesh white corundum powder, 6 parts of gray calcium powder, 8 parts of heavy calcium powder, 12 parts of polyvinyl alcohol, 9 parts of emery, 15 parts of polyimide 3 parts, 3 parts of glass fiber, 45 parts of water-based polyurethane, 4 parts of zinc oxide, 30 parts of deionized water.
