摘　　要：以AlF3-KF共晶化合物钎剂为基础,在不改变其无腐蚀性质的情况下,通过添加助剂,对其进行改性。添加无机助剂,提高了钎剂的去膜能力和助焊性;添加有机助剂,提高了钎剂在水中的抗沉降性能,从而达到能高效应用于钎焊铝制热交换器的目的。Based on the AlF3 -KF eutectic compound fluxes, under the circumstances of not changing the non-corrosive nature, by adding additives, the eutectic compound fluxes are modified. By adding inorganic additives, the abilities of removing the oxide film and solderability are improved;And through adding organic additives, the settling property in water is improved, the purpose of efficient use in brazing aluminum heat exchanger is achieved.
