電工鋼硅鋼片自粘硅鋼片定子手工膠粘方案由于其需要復(fù)雜的人工操作及復(fù)雜的疊壓工裝，其生產(chǎn)效率不高，并且生產(chǎn)存在一定的報廢率，隨著技術(shù)的發(fā)展，近年來多個鋼廠均推出了自粘硅鋼片；自粘硅鋼片是指硅鋼片在冷軋完之后，硅鋼片廠家在硅鋼片表面涂覆了一層有機(jī)的涂層（比如寶鋼的Z涂層和Sura Cogent的Suralac 9000），此涂層同時具備C5涂層的絕緣性，又具備膠水的粘性；硅鋼片在生產(chǎn)完之后，自粘涂層是不帶有粘性的（B 狀態(tài)），當(dāng)產(chǎn)品在一定溫度和一定壓力情況下，自粘涂層會進(jìn)行融化并形成固化強(qiáng)度將硅鋼片粘接到一起，以達(dá)到膠粘的效果；對比與普通的硅鋼片自粘硅鋼片的相關(guān)參數(shù)如圖：

電工鋼硅鋼片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.
