style="text-indent:25px">【正盟環(huán)保】助焊劑種類助焊劑按功能分類有：手浸焊助焊劑、波峰焊助焊劑及不銹鋼助焊劑；前面兩者為廣大用戶所熟悉了解，這里解釋不銹鋼助焊劑,它是專門針對(duì)不銹鋼而焊接的一種化學(xué)藥劑，一般的焊接只能完成對(duì)銅或錫表面的焊接，但不銹鋼助焊劑可以完成對(duì)銅、鐵、鍍鋅板、鍍鎳、各類不銹鋼等的焊接；助焊劑的種類很多，大體上可分為有機(jī)、無機(jī)和樹脂三大系列。樹脂焊劑通常是從樹木的分泌物中提取，屬于天然產(chǎn)物，沒有什么腐蝕性，松香是這類焊劑的**，所以也稱為松香類焊劑。由于焊劑通常與焊料匹配使用，與焊料相對(duì)應(yīng)可分為軟焊劑和硬焊劑。廠家直銷光伏組件助焊劑，質(zhì)量保證，價(jià)格優(yōu)惠。臺(tái)州錫絲助焊劑</p><p
