LW-19無鉻鈍化劑使鋁合金表面生成致密均勻的化學轉(zhuǎn)化膜,可有效提升鋁合金表面與涂層結(jié)合的漆膜附著力以及耐腐蝕性。
特性:
1、環(huán)保:無鉻、無毒、不含重金屬;
2、簡便:工藝簡單、控制范圍寬;
3、節(jié)能:常溫處理,可使用自來水配槽;
4、性能:槽液穩(wěn)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(chǎn)品,不含金屬鉻或其它任何重金屬,因此,除油產(chǎn)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(jù)國家法律法規(guī)及當?shù)卣欧艠藴蔬M行廢水排放。
LW-19 Chromium-free
Passivation
Additive
LW-19 Chromium-free Passivation Additive(Liquid)
can make aluminum alloy surface form the uniform chemical conversion film which could effectively enhance the coating film adhesion and corrosion resistance to the aluminum alloy 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.
