仕様
1.非- 腐食性と非- 吸湿性2.ポスト治療を必要としませんろう付け接合部分の
Hz-qj202フラックスは、 白色微粉末から成るの混合物をfluroroaluminate塩類がカリウムは非腐食性と非吸湿性である。 the flux of the highest quality and consistency is produced under stringent process tolerances and a variety of quality control procedures by us。
The flux has a melting point ポイント of 558・度; c to 620・度; c、 この真下を共晶al-si系ろう付け合金の温度。 サイズにあるそのthe particle1um50μmの範囲に。
During the brazing process the flux dissolves the oxide layer on aluminum and allow the filler me-tal to flow freely into the joints by capillary action。 after cooling、 the flux residue remains on the surface as a thin adherent film and is noncorrosive and nonhygroscopic。 the flux does not require post brazing treatment of the joint area。

Brazing process
1. cleaning : the surface to be brazed must be pre- cleaned to achieve a water Wettable surface。
2. flux application : usually as a water based slurry。 typical the slurry Concentration is in the range of 3% to 25％。
3. drying : To achieve a successfully brazed component it is essential that all Water is removed from the flux coating。 a drying process is carried out at Approximately 180・度; c - 250・度; c。
4.the process requirement of brazing furnace:
Inert atmosphere - usually nitrogen as this is the cheapest。
Dewpoint less than minus 40・度; c。
Operating temperature range of 558-620・度; c、 coinciding with the melting point の The cladding。
Rate of heating of the component greater than 20・度; c per minute。
