style="text-indent:25px">【正盟環(huán)保】助焊劑作用助焊劑中的主要起作用成分是松香，松香在260攝氏度左右會被錫分解，因此錫槽溫度不要太高．助焊劑是一種促進(jìn)焊接的化學(xué)物質(zhì)。在焊錫中，它是一種不可缺少的輔助材料，其作用極為重要。溶解焊母氧化膜在大氣中，被焊母材表面總是被氧化膜覆蓋著，其厚度大約為2×10-9～2×10-8m。在焊接時(shí)，氧化膜必然會阻止焊料對母材的潤濕，焊接就不能正常進(jìn)行，因此必須在母材表面涂敷助焊劑，使母材表面的氧化物還原，從而達(dá)到消除氧化膜的目的。被焊母材再氧化母材在焊接過程中需要加熱，高溫時(shí)金屬表面會加速氧化，因此液態(tài)助焊劑覆蓋在母材和焊料的表面可防止它們氧化。環(huán)保級助焊劑，可免除清洗工序，進(jìn)而節(jié)約制造商的生產(chǎn)費(fèi)用和工作時(shí)間。</p><div
