LW-19無鉻鈍化劑是一種無色透明的環保型酸性處理劑，采用復合鹽類在鋁基體表面生成致密均勻的化學轉化膜，可有效提升鋁合金表面與涂層結合的漆膜附著力以及耐腐蝕性能。槽液配制簡單、工藝控制方便、工作性能穩定。
特性：
1、環保：無鉻、無毒、不含重金屬；
2、簡便：工藝簡單、控制范圍寬；
3、節能：常溫處理，可使用自來水配槽；
4、性能：槽液穩定，皮膜無顏色呈透明，同樣適合晶泳涂裝工藝的前處理。
廢水處理：
LW-19無鉻鈍化劑是一款可水洗的無鉻鈍化產品，不含金屬鉻或其它任何重金屬，因此，除油產生的廢水和無鉻鈍化槽液廢水排放時加入生石灰和片堿中和至PH 6.5-7.5呈中性即可。具體排放標準請根據國家法律法規及當地政府排放標準進行廢水排放。
LW-19 Chromium-free
Passivation Additive
LW-19 Chromium-free Passivation Additive
is a kind of colorless transparent and environmental protection additive. It applies the composite metal salts to form the uniform chemical conversion film on aluminum surface which can effectively enhance the coating film adhesion and corrosion resistance to the surface and the coating.
Features:
1) Environmental protection: LW-19 is a kind of chromium-free, non-toxic and no heavy metals additive;
2) Simple: Simple process, wide control range;
3) Energy-saving: Operation at room temperature, bath make-up can apply running water;
4) Performance: Bath solution is stable and the coating film is of no color (transparent), it is also applicable for crystalphoresis pretreatment.
Waste water treatment：
LW-19 chromium-free passivation additive is a washable chromium-free passivation product, which does not contain chromium or any other heavy metals. Thus, before discharging the waste water of degresing bath and chromium-free passivation bath, can apply quick lime and sodium hydroxide to neutralize the waste water PH to be 6.5-7.5 is ok. Specific discharge standards should be according to national laws and regulations and local government discharge standards.
