LW-19无铬钝化剂是一款可水洗的无铬钝化产品,不含金属铬或别的任何重金属。因而,除油发生的废水和无铬钝化槽液废水排放时参加生石灰和片碱中和至PH 6.5-7.5呈中性即可。详细排放尺度请依据国度执法法例及外地当局排放尺度举行废水排放。
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.
LW-14 Chromium-free
Degreasing Additive
LW-14 Chromium-free Degreasing Additive is a kind of colorless to yellowish transparent liquid with powerful degreasing surface active agent, emulsifier and functional agent.This product can efficiently remove aluminum surface grease, stains and natural oxidation film and results no harm to aluminum profiles. LW-14 is used for pre-treatment of aluminum profiles powder coating and anodization. It has advantages of low cost, little aluminum consumption and energy-saving comparing to alkaline etching treatment..
