Steel powder coated gold small module planetary gear for Lawn mower.
The worm gear structure is commonly used to transmit the motion and power between two interleaved shafts. The worm wheel and the worm are equivalent to the gear and the rack in the middle plane, and the worm and the screw are similar in shape.
Powder coating is a solid powdery synthetic resin coating composed of solid resin and pigments, fillers and additives. Unlike ordinary solvent-based paints and water-based paints, its dispersion medium is not solvent and water, but air. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption.
Powder coating is a completely different form from general coatings, and it exists in the state of fine powder. Since no solvent is used, it is called powder coating.
The main characteristics of powder coatings are: harmless, high efficiency, resource saving and environmental protection.
1. Thermosetting powder coating refers to the use of thermosetting resin as the film-forming substance, and the curing agent for cross-linking reaction can be heated to form an insoluble and infusible hard coating. No matter how high the temperature is, the coating will not soften like a thermoplastic coating, but can only decompose. Since the resin used in thermosetting powder coatings is a prepolymer with a lower degree of polymerization and a lower molecular weight, the coating has better leveling properties and better decoration. Moreover, after the low molecular weight prepolymer is cured, It can form network cross-linked macromolecules, so the coating has better anti-corrosion and mechanical properties. Therefore, the development of thermosetting powder coatings is particularly rapid.
1.1 Epoxy powder coating. Because of its excellent adhesion to metals, corrosion resistance, hardness, flexibility and impact strength, it is the first variety to be used in thermosetting powder coatings. The preparation of epoxy powder coating is composed of epoxy resin (Epoxy Resin), curing agent (curing agent), pigment (pigment), filler (filler) and other assistants (assistant). The contribution of these several components to the performance of the formed powder coating is mutually restricted and affects each other. An appropriate formula is actually the result of coordination of various components.
1.2 Polyester powder coating. Compared with other types of powder coatings, polyester powder coatings have unique properties. It has better weather resistance and UV resistance than epoxy resin . In addition, because the polyester resin has polar groups, the powdering rate is higher than that of epoxy resin. It is not easy to turn yellow during the baking process, has high gloss, good leveling, full paint film, and light color. Very decorative.
