电工钢硅钢片自粘接涂层Z C3 C-3 - C-3涂层为有机成分，具有很高的层间电阻，并可以大幅提高钢带的冲片性能，很适合用于冲压叠片。用户使用时，先将钢板冲制成铁心叠片，然后加压固定成型，在保压条件下加热固化，叠片彼此粘接在一起，形成整体。其固定方式和常见的铆接、广西同城焊接、广西同城螺栓方式不同，刚度、广西同城强度更高，振动和噪音小。涂层交货状态为 B 状态，即涂层还没有发生完全固化，具有进一步粘接、广西同城固化的活性，涂层硬度、广西同城耐蚀性尚没有达到 。涂层钢卷仓储有效期为半年。用户固化的工艺为：a）炉烘温度 160～230℃，模具压紧的压力为 0.3～3Mpa，时间保持1～3h；或 b）感应固化的铁心温度 150~250℃，压力 0.1~3MPa，时间保持 0.2~30min。固化后，涂层处于终稳定的状态，即 C 状态，涂层硬度、广西同城强度、广西同城粘接力达到 。涂层不能承受正常的应力退火温度。涂层能承受 180℃的长期耐热温度；但考虑到粘结能力的稳定性，适用于该涂层的工作温度通常不超过 150℃。
电工钢硅钢片Electrical steel, also known as silicon steel sheet, is an indispensable metal material in the power, electronics, and military industries, and is also the largest functional material in production. It is mainly used as the iron core for various motors, generators, and transformers. Specific total loss (iron loss) is the total power consumed per unit mass of material when the magnetic polarization waveform remains sinusoidal, with a specific peak and frequency. The specific total loss is represented by the symbol P (Jm/f), in W/kg. Example: P1.5/50 represents the specific total loss at a maximum magnetic polarization intensity of 1.5T and a frequency of 50Hz. 3.2 Magnetic Polarization Q/BQB 480-20212 Magnetic polarization intensity refers to the peak magnetic polarization intensity of a specific magnetic field intensity when a sample is subjected to alternating magnetization. Its symbol is J (H), and the unit is T (Tesla). Example: J5000 represents the peak magnetic polarization intensity corresponding to a magnetic field intensity peak of 5000A/m. The material grades in this document are classified based on the nominal maximum specific total loss P1.5/50 (W/kg) at a magnetic polarization strength of 1.5T and a frequency of 50Hz, as well as the nominal thickness of the material. They are further divided into three categories based on product characteristics: ordinary type, stress relief annealing type, and high-efficiency type. Example 1: B35A210 represents a common non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific total loss value P1.5/50 is 2.10W/kg； Example 2: B35AR300 represents a stress relieved annealed non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific total loss value P1.5/50 is 3.00W/kg； Example 3: B35AH230 represents an efficient non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.30W/kg. Example 4: 35WW210 represents a normal type WW non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.10W/kg. Example 5: 35WH230 represents an efficient WH non oriented electrical steel with a nominal thickness of 0.35mm, and the maximum nominal specific loss value P1.5/50 is 2.30W/kg. The classification and code of insulation coatings shall comply with the provisions of Table 2. Table 2 Classification and Code of Insulation Coatings Type Code Characteristics of Insulation Coatings Semi organic Thin Coating A Improves Punching Performance and Has Good Weldability Semi organic Thick Coating H has Good Punching Performance and High Interlayer Resistance Semi organic Chromium Free Thin Coating K does not contain chromium and has good weldability Semi organic Chromium Free Thick Coating M does not contain chromium and has good insulation performance Semi organic Chromium Free Extreme Thick Coating J does not contain chromium and has excellent insulation performance Semi organic Chromium Free Ultra Thick Coating L does not contain chromium and has extremely high insulation performance Self adhesive Coating
