The latest method for removing the enamel coating from copper wire

2022-07-20

1. The copper wire stripping method (BT-104 copper wire stripping powder) is specifically designed for removing the enamel coating from AI (200-grade) and PI (220-grade) wires used in voice coils, and is suitable for use on assembly lines.

2. Method for removing varnish from enameled copper wire (using BT-104 copper wire varnish removal powder): Heat to 300–350℃ and apply directly to melt the varnish coating completely, leaving no residue behind.

3. Method for stripping enamel from copper wire (BT-104 Copper Wire Stripping Powder): Environmentally friendly (RoHS-compliant), fast—removal takes only 3–5 seconds.

Operating parameters (Technical parameters):

The BT-104E enameled wire stripper is white and powdery;

Process:

Enamelled wire → Immerse in stripping agent for 3–5 seconds (heated to 300–350℃) → Rinse with water → Immerse in BT-122 red solution → Rinse with water → Solder

Packaging, Transport and Storage

The BT-104 is packaged in acid- and alkali-resistant plastic bottles with a capacity of 500 g per bottle. Each carton contains 20 bottles.

This product should be stored in a dark, dry place at a temperature below 25°C and kept separate from organic materials, reducing chemicals, and acidic substances. The shelf life is 12 months.

During transportation, protect the product from exposure to sunlight and rain, high temperatures, leakage, compression, and breakage.

Attention

Since this product is used under high-temperature conditions, you should take care to wear protective gloves, protective clothing, a mask, and goggles when using it. Avoid contact with skin to prevent splashes from injuring your eyes and skin. If the product does splash onto your skin, rinse thoroughly with plenty of water (seek medical attention if symptoms are severe). During the initial heating process, be sure to cover the container with an iron lid to prevent paint stripper powder from splashing due to uneven heating as it melts. Only open the lid and use the product normally once the paint stripper powder has completely melted. Since the paint stripper powder is highly hygroscopic, after ceasing use, store it in a tightly sealed container to prevent it from absorbing moisture. If you plan to reuse it, first wipe off any surface moisture with a dry cloth or paper towel, then cover the container and heat it up to 100°C for a period of time. Once all the moisture has evaporated, increase the temperature to the working range of 350–380°C.

A leader in technology and quality among silver-plated wire manufacturers.

In high-tech fields such as electronics, telecommunications, aerospace, and defense industries, silver-plated wires—high-performance conductors—are highly favored for their excellent electrical conductivity, thermal conductivity, corrosion resistance, and ability to withstand high temperatures and oxidation. The manufacturers behind these silver-plated wires are the very pioneers in technology and the key producers of these premium-quality products. The technological prowess of silver-plated wire manufacturers serves as the fundamental guarantee of their product quality. Typically, these manufacturers have a dedicated R&D team that continuously introduces new technologies and processes, striving to enhance both the performance and quality of silver-plated wires. They conduct in-depth research into the silver-plating process, optimizing the thickness and density of the silver coating to improve its corrosion resistance and antioxidant properties. At the same time, they rigorously screen raw materials, ensuring that high-quality oxygen-free copper is used as the substrate, thereby further boosting the conductivity and thermal conductivity of the silver-plated wires. The production process of silver-plated wires is a meticulous and complex procedure. Before starting, manufacturers pre-treat the raw materials to remove surface oils and oxides, ensuring the purity of the substrate. Next, the substrate is placed in silver-plating equipment, where a thin layer of silver is electroplated onto its surface through electrolysis or other methods. Following this, the wires undergo processes such as drawing and annealing to achieve the desired diameter and performance characteristics. Finally, manufacturers subject the silver-plated wires to stringent quality inspections.

The core material in the electrical wire industry—enameled copper round wire.

In the electrical industry, enameled copper round wire is an indispensable wire material. Widely used in electrical equipment, electronic devices, household appliances, and other fields, it facilitates the conversion of electromagnetic energy and plays a crucial role in key devices such as motors and transformers. This article introduces the characteristics, manufacturing processes, and application areas of enameled copper round wire. Enameled copper round wire, also known as winding wire, consists primarily of two parts: the conductor and the insulation layer. The conductor is typically made from high-purity electrolytic copper, which boasts excellent electrical conductivity. The insulation layer is formed by coating the conductor surface with a special insulating varnish that, after being cured at high temperatures, develops outstanding insulating properties and wear resistance. A distinctive feature of enameled copper round wire is the tight bond between its conductor and insulation layer, which not only ensures superior electrical conductivity but also effectively prevents short circuits and leakage currents. The production process of enameled copper round wire involves multiple stages. High-purity electrolytic copper undergoes a drawing process to produce copper wires with gradually decreasing cross-sectional areas and increasing lengths. These copper wires are then coated on their surfaces using specialized painting machines; the applied varnish is subsequently cured in a drying oven, forming a uniform insulating layer. After painting, the copper wires undergo diameter adjustments to meet the requirements of various application scenarios. Through lamination and finishing processes, the enameled wire achieves a more robust insulation structure and enhanced performance.
