We have developed a set of supersonic atomizing equipment with the base theory of the supersonic atomization and the base characteristic of the solder alloy . the paper studies systematic the production technology and process of the solder alloy fine powders in the equipment , and deduces the gas velocity formula used in supersonic atomization in theory 為此,運(yùn)用超音速霧化的基本原理和焊錫合金的基本性質(zhì),研制出一套超音速霧化裝置,在該裝置上對(duì)焊錫合金微粉的制備技術(shù)及工藝進(jìn)行了系統(tǒng)的研究,并從理論上推導(dǎo)出適用于超音速霧化的氣體速度公式。
