For areas where pretreatment does not meet requirements, use electric grinders to achieve St3 grade.Application Methods:Pre-coating: Use a brush to apply one coat on welds, corners, edges, screw holes, plate edges, and hard-to-reach areas for pre-coating. Air spray: Connect air source to an oil-water separator, use a 2.5mm nozzle for air spray, maintain a distance of about 25cm between the gun and the object surface, spray width approximately 15cm, apply two passes, wait 1 hour before applying the second coat with two cross passes to achieve the required thickness. Airless spray: Use specialized spraying equipment for zinc-rich coatings with a Z-type nozzle, ensure the entire equipment is clean, recommended compression ratio around 1:30, spray width about 25cm.Brush application: Use high-quality brushes that do not shed fibers, apply evenly using a cross method to ensure good penetration of the coating, avoid sagging and unevenness.Construction Guidance:Note: Theoretical consumption is calculated based on parameters; actual consumption may vary significantly depending on the user's application method, the shape of the sprayed workpiece, surface treatment process, film thickness, etc.Coating Interval: Recoating interval: 1 hour for self-recoating, 2-8 hours for other coatings. Avoid moisture before the coating is fully dry. High zinc coatings can form zinc salts (white rust) on the surface; they should not be exposed for extended periods before applying the next coat. If zinc salts have formed, perform secondary removal treatment on the affected surface.Application Conditions: Environmental conditions: 0°C to 50°C, relative humidity during application less than 85%, no dust in the air.Preparation: Stir the contents in the bucket thoroughly from the bottom to ensure uniformity before use.Packaging Specification: 25KG/drumShelf Life: 12 months more>

Product Description: The ultrasonic children's water bottle strap welding machine is a device that utilizes the principle of ultrasonic vibration to efficiently, cleanly, and pollution-free weld nylon webbing. The following is a detailed introduction to this equipment:1. The working principle of the ultrasonic children's water bottle strap welding machine is based on ultrasonic vibration. The transducer (ultrasonic vibrator) inside the device generates high-frequency vibration waves (typically 20-40kHz), which are transmitted through the upper welding component to the interface of the nylon webbing to be welded. Due to the high acoustic resistance at the interface, the vibration waves generate localized high temperatures there. Simultaneously, friction between the nylon materials causes the nylon at the contact surfaces to melt rapidly, fusing together under pressure. After the ultrasonic action stops, a certain pressure is maintained to allow the melted nylon material to cool and solidify, forming strong molecular chains, thereby achieving the purpose of welding.2. Main ComponentsUltrasonic Generator: Generates high-frequency electrical signals to drive the transducer's vibration.Transducer: Converts electrical signals into high-frequency mechanical vibrations and is the core of ultrasonic energy conversion.Horn (Vibration System): Transmits the vibrations generated by the transducer to the nylon webbing to be welded.Welding Mold: Customized according to the shape and size of the nylon webbing, used to fix and position the webbing, ensuring welding precision and stability.Pressure System: Applies appropriate pressure during the welding process to ensure the melted nylon material adheres closely. more>

Product Description: Pei Yingying  186258  79268Design of Sacrificial Anodes1. Process CalculationThe calculation content of sacrificial anode design includes anode grounding resistance, anode output current, required number of anodes, and anode service life. Since the current generated by a single sacrificial anode is limited, and the underground pipeline has resistance, which causes the current to diverge, the protection range of a single sacrificial anode is local. For the entire pipeline, multiple sacrificial anodes must be connected in parallel to achieve protection collectively.(1) Calculation of Anode Grounding ResistanceGrounding resistance is the resistance formed at the interface between the sacrificial anode and the soil. The magnitude of this resistance directly affects the current output of the sacrificial anode and is a key parameter for the protection area and degree of sacrificial anode protection.For single horizontal and vertical cylindrical sacrificial anodes, when La (length of the anode backfill layer) is much larger than d (equivalent diameter of the anode), and t (distance from the anode center to the ground) is much larger than L/4 (L is the anode length), the anode grounding resistance can be calculated using Equations (5-1) to (5-3).For a single vertical cylindrical sacrificial anode without backfill, the grounding resistance is:(5-1)For a single vertical cylindrical sacrificial anode with backfill, the grounding resistance is:(5-2)For a single horizontal cylindrical sacrificial anode with backfill, the grounding resistance is:(5-3)In the equations, Rv is the grounding resistance of the vertical anode, Ω; RH is the grounding resistance of the horizontal anode, Ω; ρ is the soil resistivity, Ω·m; ρa is the backfill material resistivity, Ω·m; L is the anode length, m; La is the length of the anode backfill layer, m; d is the equivalent diameter of the anode, m; D is the diameter of the backfill layer, m; t is the distance from the anode center to the ground, m.The total grounding resistance of multiple anodes in parallel is larger than the theoretical value due to the interaction between anodes. It can be corrected based on the spacing between anodes:(5-4)In the equation, Rtotal is the total grounding resistance of the anode group, Ω; Rv is the grounding resistance of a single anode, Ω; N is the number of parallel anodes; η is the correction coefficient, refer to Figure 5-2.Pei Yingying   1862587  9268 more>
