釹鐵硼的鍍層Neodymium iron boron coating

由于釹鐵硼磁鋼基體易氧化和易受腐蝕，為了保護磁鋼，一般需要不同的鍍層，常用的鍍層有：鎳銅鎳、藍白鋅、彩鋅、環氧、磷化、特富龍...... Because the matrix of Nd-Fe-B magnetic steel is easy to be oxidized and corroded, different coatings are generally required to protect the magnetic steel. The commonly used coatings are: nickel copper nickel, blue white zinc, color zinc, epoxy, phosphating, Teflon

鎳銅鎳鍍層磁鋼Nickel copper nickel coated magnetic steel

鎳銅鎳鍍層具有優秀的耐腐蝕性能、硬度、耐磨性等綜合物理化學性能，暴露于復雜的大氣環境中，保證外觀與內在性能的長期穩定和較長的使用壽命。對于釹鐵硼來說，是一種最常見的鍍層之一。 Nickel copper nickel coating has excellent corrosion resistance, hardness, wear resistance and other comprehensive physical and chemical properties. It is exposed to complex atmospheric environment to ensure long-term stability of appearance and internal performance and long service life. Neodymium iron boron is one of the most common coatings.

藍白鋅鍍層磁鋼Blue white zinc coated magnetic steel

鋅鍍層一般較薄，防腐性相對較好，鍍層經鈍化后外觀漂亮，色澤較美觀，磁鋼中心與邊角鍍層的“骨頭效應”不明顯，對產品公差較緊產品也可滿足。可使用于抗短期污染變色的有限腐蝕性場合。 The zinc coating is generally thin and has relatively good corrosion resistance. After passivation, the coating has a beautiful appearance and beautiful color. The "bone effect" of the coating at the center and corners of magnetic steel is not obvious, which can also be met for products with tight product tolerance. It can be used in limited corrosive occasions with resistance to short-term pollution and discoloration.

彩鋅鍍層磁鋼Color zinc coated magnetic steel

彩鋅鍍層具有普通藍白鋅鍍層的特點外，具有比藍白鋅鍍層更高的防腐性。可使用于較為苛刻的氣氛環境中。 Color zinc coating has the characteristics of ordinary blue and white zinc coating, and has higher corrosion resistance than blue and white zinc coating. It can be used in harsh atmosphere.

環氧樹脂鍍層磁鋼Epoxy resin coated magnetic steel

環氧樹脂具有良好的物理、化學性能，對金屬和非金屬材料的表面具有優異的粘接強度，介電性能良好，變定收縮率小，制品尺寸穩定性好，硬度高，柔韌性較好，對堿及大部分溶劑穩定。我司采用電鍍鎳銅之后再涂裝環氧樹脂工藝，產品具有優異的粘結能力和耐腐蝕能力。 Epoxy resin has good physical and chemical properties, excellent bonding strength to the surface of metal and non-metallic materials, good dielectric properties, small variable shrinkage, good dimensional stability, high hardness, good flexibility, and stable to alkali and most solvents. Our company adopts the process of electroplating nickel copper and then coating epoxy resin. The products have excellent bonding ability and corrosion resistance.

磷化鍍層磁鋼Phosphate coated magnetic steel

磷化用于給基體金屬提供保護，在一定程度上防止金屬被腐蝕，具有無鍍層厚度的特點。在涂漆前打底，可提高漆膜層的附著力與防腐蝕能力。 Phosphating is used to protect the base metal and prevent the metal from corrosion to a certain extent. It has the characteristics of no coating thickness. Priming before painting can improve the adhesion and anti-corrosion ability of the paint film.

特氟龍鍍層磁鋼Teflon coated magnetic steel

特氟龍具有獨特優異的耐熱（180～260℃），耐低溫（－200℃）及介電性能等。它具有最高的工作溫度（260℃）和最好的化學穩定性，除熔融的堿金屬、高溫和二氟化氛外，尚無其他化學物質能對它產生侵蝕。它還有優良的耐候性，一般可在戶外使用10年以上。具有低的摩擦系數，其潤滑性，特別是自潤滑 Teflon has unique and excellent heat resistance (180 ~ 260 ℃), low temperature resistance (- 200 ℃) and dielectric properties. It has the highest working temperature (260 ℃) and the best chemical stability. Except for molten alkali metal, high temperature and difluorination atmosphere, no other chemical substances can erode it. It also has excellent weather resistance and can be used outdoors for more than 10 years. It has low friction coefficient and its lubricity, especially self lubrication
