环保多功能碱性除油剂
LW-31环保多功能碱性除油剂适用于铝及其合金阳极氧化工艺前处理工序,能有效去除基材表面自然氧化膜、油污、毛刺、喷砂基材表面浮砂等,并无需酸性中和除灰,便可获得洁净、均匀、细腻、柔和的金属表面。
碱性除油工艺与传统工艺的项目对照表:
工艺类型 项目 | 传统前处理工艺 | 碱性除油处理工艺 |
生产工序复杂性 | 工序复杂,影响生产效率。标准前处理工艺槽数量为10个。 | 工序缩减为5个槽:弱酸水洗--水洗--碱性除油--水洗--水洗--氧化。 |
酸性废水产生量 | 产生大量酸性(含氟)废水,生产每吨铝材产生废水量为5—8吨。占整条氧化线产生酸性废水量的大部分。 | 不产生酸性废水,相反生产每吨铝材产生约2—3吨碱性废水。节约了大量废水处理成本。 |
铝损耗 | 铝损耗较大,生产每吨铝材铝损耗在4—8公斤,按年产量1万吨计算,每年挤压坯料浪费重量40—80吨。 | 铝损不及碱腐蚀的十分之一,平均约为0.4公斤/吨,每年节约的原材料成本非常可观。 |
废渣产生量 | 产生大量废渣,增加了生产成本。氧化废渣七成以上由前处理产生。 | 产生的废渣不及传统工艺的十分之一。大幅缩减废渣处理成本。 |
车间环境 | 碱腐蚀槽在工作时会产生大量碱雾,不仅恶化了生产人员的工作环境,对车间设备及氧化、电泳工艺也会有破坏作用,增加了管理成本。 | 无碱雾、碱味污染空间。对车间环境友好。

LW-31 Eco-friendly & Multi-functional
Alkaline Degreasing Additive
(Liquid)
LW-31 Eco-friendly&Multi-functional Alkaline Degreasing Additive is suitable for pre-treatment of anodic oxidation process to aluminum and its alloys. It can effectively remove natural oxide film, oil stain, burr, floating sands on the surface of the sand-blasted aluminum profiles and no need to go through the acid neutralization process but the clean, uniform, delicate and soft metal surface can be obtaines.
Comparisons of alkaline degreasing process with traditional process:
Process Items | Traditional pretreatment process | Alkaline Degreasing Process |
Complexity of production process | The process is complex which affects the production efficiency. The number of standard pretreatment process baths is 10. | The process can be reduced to five baths: weak acid rinsing→ rinsing →alkaline degreasing→ rinsing -rinsing → oxidation |
Acidic waste water amount | A large amount of acidic (fluoride- containing) waste water is produced and the amount of waste water produced in the production of per ton aluminum profile is 5-8 tons. It accounts for most of the acidic waste water producedby the whole oxidation line. | No acidic waste water is produced,on the contrary, about 2-3 tons of alkaline waste water are produced per ton of aluminum profiles treatment which can save largeamount of waste water treatment cost. |
Aluminum loss | The loss of aluminum is large. The loss of aluminum is 4-8 kg per ton of aluminum profile in production. According to the annual output of 10,000 tons, the waste weight of extruded profile is 40-80 tons per year. | The loss of aluminum is less than one tenth of that of alkaline etching, the average aluminum loss is about 0.4 kg/ton. The annually saved cost of raw materials is very considerable. |
Waste residue amount | A large amount of waste residue is produced,which increases the production cost. More than 70% of the oxidized waste is produced by pretreatment. | The waste residue produced is less than one tenth of the traditional process. This can greatly reduces waste residue treatment cost. |
Workshop environment | Alkaline etching bath will produce a lot of alkali fog when it works, it is not only deteriorates the working environment of the workers, but also destroys the workshop equipment, oxidation and electrophoresis process, and increases the management cost. | No alkali fog and alkali odor produced which achieves a friendly workshop environment. |
