磁性材料：Magnetic core material

磁芯材料噴涂

釹鐵硼

，簡單來講是一種磁鐵，含有大量的稀土元素釹

、以及鐵及硼，其特性硬而脆

。釹鐵硼作為稀土永磁材料的一種具有極高的磁能積和矯頑力

，同時高能量密度的優(yōu)點使釹鐵硼永磁材料在現(xiàn)代工業(yè)和電子技術中獲得了廣泛應用，從而使儀器儀表

、電聲電機

、磁選磁化等設備的小型化

、輕量化、薄型化成為可能

。

由于表面極易被氧化腐蝕

，釹鐵硼必須進行表面涂層處理。表面化學鈍化是很好的解決方法之一

。

NdFeB, which is simply a magnet, contains a large amount of rare earth element lanthanum, as well as iron and boron, and its characteristics are hard and brittle. As a kind of rare earth permanent magnet material, NdFeB has the extremely high magnetic energy product and coercive force, and the high energy density makes NdFeB permanent magnet material widely used in modern industrial and electronic technology, thus making it possible to miniaturize, lightweight and thin, in the instrument of electroacoustic motors, and magnetic separation magnetization.

Because of the surface highly susceptible to oxidative corrosion, NdFeB surface must be coated. Surface chemical passivation is one of the best solutions.

磁芯材料生產工藝流程：Magnetic core material production process:

磁粉（粒度調整）-配粉（混膠與造粒）--壓制成型—磁體固化—倒角與清洗—涂裝與固化—充磁—磁體固化Magnetic powder (grain size adjustment)--powder preparation (mixing and granulation)--press molding-magnet curing-chamfering and cleaning-coating and fixing-magnetization-magnet curing

行業(yè)痛點：Industry pain points:

傳統(tǒng)人工噴涂

、產品小，用傳統(tǒng)的手工噴涂方式

，涂料利用率不到10%

，涂料浪費率高

；

The product is small, and the adhesive utilization rate is less than 10%, using the traditionally spraying method manually, waste rate is high;

、零件需要全身涂裝

，用傳統(tǒng)的手工噴涂方式

，噴涂、干燥

、翻面需要多次周轉

，效率低下

；

The parts need to be painted fully, and the spraying, drying, turning over surface requires multiple turnover, using the traditional manual spraying method, low efficiency;

3、傳統(tǒng)滾噴方式

，噴涂質量需要人工控制

，對工人的技術要求高，質量不穩(wěn)定

。

The traditional rolling spraying quality needs manually control, requirements high technical of the workers, but unstable product quality.

4、涂料附著力不夠強

、高溫或摩擦下易掉漆

；

The adhesion is not strong enough, easily fall off under high temperature or friction;

5、噴涂時易出現(xiàn)粘黏現(xiàn)象

。

Sticky phenomenon is frequently during the spraying.

6、噴涂對車間人員及環(huán)境造成污染

。

Spraying causes pollution to the workshop personnel and the environment.
