LW-14无铬专用除油剂(液

   LW-14无铬专用除油剂(液)为无色至淡黄色透明液体,含有强力脱脂表面活性剂、乳化剂及功能性添加剂,能有效地去除铝型材表面的油脂、污渍及自然氧化膜,对铝基材无伤害。用作铝型材喷涂、阳极氧化工艺的前处理,相对碱蚀处理而言,它具有成本低廉、铝耗少和节省能源等优点。

   LW-14 Chromium-free 
   Degreasing 
   Additive (Liquid)
   LW-14 Chromium-free Degreasing Additive (Liquid) 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.


LW-19无铬钝化剂(液)


   LW-19无铬钝化剂(液)使铝合金表面生成致密均匀的化学转化膜,可有效提升铝合金表面与涂层结合的漆膜附着力以及耐腐蚀性。

   特性:

   1、环保:无铬、无毒、不含重金属;

   2、简便:工艺简单、控制范围宽;
   3、节能:常温处理,可使用自来水配槽;

   4、性能:槽液稳定,皮膜无颜色呈透明,同样适合晶泳涂装工艺的前处理。

   废水处理:

   LW-19无铬钝化剂是一款可水洗的无铬钝化产品,不含金属铬或其它任何重金属,因此,除油产生的废水和无铬钝化槽液废水排放时加入生石灰和片碱中和至PH 6.5-7.5呈中性即可。具体排放标准请根据国家法律法规及当地政府排放标准进行废水排放。

   LW-19 Chromium-free Passivation Additive(Liquid)
   This product 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.
