How to distinguish between hot dip galvanized solar street lamp light pole?

The solar street light light pole without any preservative measures only 2 - service life 3 years, after the service life of cold galvanizing of solar street light light pole can only improve one year, namely 3 - 4 years, and after hot dip galvanized solar street light pole can use more than 30 years and not

how to identify hot dip galvanized solar street light lamp?

everybody know, solar street lamps are all sure to must after hot dip galvanized, after hot dip galvanized solar street lamp, can be applied more long-term, led solar street lamps do not hot dip galvanized could the ten times, or even dozens of times.

no after all corrosion protection countermeasures of street lamp only 2 - could the solar street lamps Three years, after cold spraying zinc could the solar street light lamps to only ascend for a year, namely 3 - Four years, and after hot dip galvanized solar street light lamp can apply above 30 years without rust.

with the basic principle of hot dip galvanizing is cold spraying zinc or spraying zinc is completely different, hot dip galvanized is to clean up the rust proofing neat after the infiltration of zinc iron street lamp pool, let the liquid, the face of positive and negative of high temperature of zinc and iron lamps are enough to touch, zinc and iron to produce zinc - very smooth and complex Metal chemicals and produce smooth zinc in the surface layer of material - Iron, zinc - Zinc iron layer of reliability is based on the quality of the water, the type of stainless steel plate, temperature control, and the time of the invasion bubble.

but anyway, this kind of zinc - Full of iron is very inseparable, it's not easy to appear off the status of the layer.

because of hot dip galvanized after the street lamp, solar street lamps in the air can be quickly converted into high density of active zinc oxide crystallization, this kind of crystal can be very reasonable to avoid further air oxidation and etching, zinc and zinc cathodic protection effect, can further maintenance of street lamp is not subject to erosion, erosion in iron, zinc repay efficacy on the etching will be migrated to zinc, in other words, only zinc thoroughly after etching, etching to iron.

namely however, hot dip galvanized as key, people should be how to identify the solar street light lamp is hot dip galvanized?

the actual way of the following:

1, burner,

hot dip galvanized and cold spraying zinc is completely different, LED street light, hot dip galvanized or without solvent is epoxy resin adhesive for bonding agent, so under the condition of fire, not prone to the condition of the surface of plastic melting, the cold spraying zinc or spraying zinc, is must be solvent or epoxy resin as the bonding agent of zinc, fire can see different significantly.

2, sharp knife method

with a sharp knife file to open the lamp surface, hot dip galvanized lamp because zinc and iron are gap junctions, so can't see level, spraying zinc or is hot and cold spraying zinc lamps, will appear in the surface of a block, can significantly see iron lamp and the level of the paint layer boundary.

3, salt water

with a sharp knife file open street lamp of a surface, wipe with salt water, maintain moisture for 24 hours, if appear serious rust, is for the cold spraying zinc or spraying zinc, if no significant erosion, twenty-four hours for hot dip galvanized.

is about how to identify whether the solar street light lamps hot dip galvanized, expect people's proposal has certain help to you.
