Embodiment 1
[0008] The surface treatment method of a sewing machine wear-resistant lubricating part described in this embodiment is to clean the surface of the needle plate of the sewing machine workpiece using zinc alloy as the base material with lye, and heat it to 120 ° C to remove oil and rust, and then Sandblasting is performed to form a sand surface on the treated surface, and then the commercially available TF-03101M Teflon paint is sprayed on the sandblasted surface, and then heated at 190°C for reinforcement and drying, and then sintered at a high temperature of 360°C. Take it out from the hot furnace and cool it down naturally to obtain a sewing machine needle plate that is both wear-resistant and lubricated after surface treatment. Here, the selected TF-03101M Teflon can be composed of 90.9 parts of tetrafluororesin, 8.1 parts of silicone, 0.8 parts of polyurethane, 0.02 parts of fluosilicic acid,
Embodiment 2
[0010] The surface treatment method of a sewing machine wear-resistant lubricating part described in this embodiment is to first use steel as the base material of the sewing machine transmission workpiece, clean the surface with lye, and heat it to 150 ° C to remove oil and rust, and then spray Sand can be sprayed with 280-mesh corundum to form a sandy surface on the treated surface, and then sprayed on the sandblasted surface with commercially available super-grade TF-03101M Teflon paint, and then heated at 210°C to reinforce and dry, and then It is sintered at a high temperature of 400°C, cooled naturally after being taken out of the furnace, and a sewing machine transmission workpiece that is both wear-resistant and lubricated after surface treatment is obtained. Here, the selected TF-03101M Teflon can be composed of 91.99 parts of tetrafluororesin, 7.2 parts of silicone, 0.8 part of polyurethane, and 0.01 part of fluosilicic acid.
