氟硼酸鈉在磷化過程中的作用
他是復(fù)雜的氟化物，可以提供氟離子，對磷化液起到重要作用�？梢约铀倭谆さ纳�，可以使鋼件表層產(chǎn)生均與的腐蝕層，尤其是可以促進鋅膜的融化，使得它表層呈現(xiàn)有利于磷酸鹽晶粒的活化區(qū)，促使磷化速度的加快進行，得到致密抗腐蝕性能強的磷化膜，升高磷化膜的抗酸性的作用。
減少酸度，氟離子是帶有負電荷的很小的離子，可以帶很大的電位，很容易和氫離子結(jié)合形成氟化氫。磷化劑離得游離酸減少時，它把氫離子放出來使磷化液酸比長期穩(wěn)定在規(guī)定的范圍內(nèi)。
降低磷化渣，氟離子和鐵離子洛河得到鐵氟絡(luò)。當(dāng)氟硼酸鈉的比例在6-8的時候可以很大程度上把磷化渣減少到最小。
遮擋雜質(zhì)，在磷化液里氯離子是肯定會存在磷化液里面的，這是因為在酸洗的過程里有氯離子會帶到磷化液中，氟離子可以遮擋氯離子。
減小磷化的溫度，便于低溫磷化液的制作。
使磷化膜的附著力更好，把磷化膜和涂層緊緊的結(jié)合在一起。因為氟離子的抗腐蝕能力很強。氟硼酸鈉很容易和水溶解，氟離子的比例小，減少氫的點位小磷化膜的形成速度慢。隨著氫離子的增多磷化膜的速度增加，膜層重量變大防銹能力好，氟離子太多，酸比增大對磷化膜不好。雖然可以增大磷化膜的厚度，但容易掉膜，鋅系磷化膜減少，發(fā)生掛灰和白斑。使得磷化膜的附著力嚴重下降，在磷化液里加氫氧化鈉也有同樣的效果。上海磷化處理
Fluorine sodium borate in phosphating process function He is a complicated fluoride, fluoride ion can provide, the phosphating liquid play an important role. Can accelerate the formation of phosphate coating, can make the steel parts are produced with the surface corrosion layer, especially can promote zinc melting of the membrane, makes it present the surface to phosphate grain activated region, make phosphate to speed up, get density corrosion resistance strong phosphating film, increased resistance of the phosphating film acid effect. Reduce acidity, fluorine ion is a negative ion is small, can take a lot of potential, very easy and hydrogen ions formed by the union hydrogen fluoride. Phosphating agent was free acid reduce, the hydrogen ion release to make phosphate liquid acid than long-term stability within a prescribed scope. Reduce the phosphate slag, fluorine ion and iron ion luohe get iron fluorine complex. When the proportion of fluorine sodium borate in 6-8 can largely reduce the phosphate slag to a minimum. Keep out impurities, in the phosphating liquid chlorine ion is sure there will be the inside of the phosphating liquid, this is because in the pickling process in chloride ion will be to the phosphating liquid, fluorine ion can keep out chloride ion. Reduce the temperature of the phosphating, low temperature phosphating solution for production. Make phosphate coating adhesion is better, the phosphate coating and coating tightly together. Because the fluorine ion corrosion resistance is very strong. Fluorine sodium borate is very easy and water solution, the proportion of fluorine ion small, reduce hydrogen point small phosphating film formation speed slow. |
