特點:RJ-5熔劑在RJ-2熔劑的基礎上加入了比例量的氟化物,進一步增強熔劑的擴散性能,表面張力和化學穩定性。其熔點和比重較鎂合金低,撒在上面,能起到熔體和空氣的隔絕作用,減少金屬在熔煉過程中的氧化、燃燒。
用途:主要用作合金覆蓋和精煉。
Characteristic: It is the RJ-2 flux with some fluoride.The melting point and specific gravity are lower than magnesium alloy which can isolate with the air to prevent the oxidation and burning.
Purpose:It is used in the refining.
