First, product characteristics
1. It is a kind of phosphorus free pretreatment agent
(1.1) complete phosphorus free environmental pretreatment agent
(1.2) no COD/BOD and no heavy metals
(1.3) a small amount of chemical treatment
(1.4) transportation and cleaning of non sediment
2. It is easy to use economy and easy to operate
(2.1) room temperature (without heating), spraying or soaking treatment.
(2.2) short reaction time (20-120 seconds)
(2.3) there is no need to do closed treatment
(2.4) no need to be made
(2.5) no waste water treatment cost
(2.5) lower cost of new line construction
3, the formation of nano ceramic coating, corrosion resistance is greater than or equal to iron phosphating / polymer seal and chromium free water washing.
4. The film weight 20-80mg/nf will produce a series of chroma range on the treated workpiece, from colorless to golden yellow.
5. In the same process, steel, zinc, hot-dip galvanized steel and aluminum materials can be processed at the same time.
Two, processing technology
Environmentally friendly phosphate free degreasing agent, which does not contain P, ZN, NI and MN, can be directly discharged.
There is no heavy metal ions such as P, FE, ZN, NI, MN and so on in the non phosphating tank. There is no sludge disposal.
Three, contrast with traditional phosphating (take spray line as an example)
