Zinc thermal spray coating material requirements and selection

 Thermal sprayed zinc coating material selection requirements and general corrosion of metal materials heat painting work, need to meet certain requirements, not all materials can be sprayed zinc work. So the process of thermal spray zinc expand what is required for it? Spray material should be how to choose? This is the thermal sprayed zinc manufacturers are concerned, today we have to give you an analysis under thermal spray zinc technology it! Zinc and zinc-aluminum alloy coated layer quality control: the appearance of quality 1) coating. Zinc and zinc-aluminum alloy coating appearance of uniform color; seamless spray phenomenon; no bubble, crack, warp, melt coarse grain and other macro defects. 2) detection of thickness of the coating. Arc spray coating is non-magnetic, steel substrate is a magnetic, with magnetic gauge to measure the thickness of non-magnetic coatings on magnetic substrates, thermal spray zinc measurement methods should be GB / T9793 a 1997 "Metallic and other inorganic coatings - Thermal spray zinc, aluminum and its alloys "to. Aluminum, zinc and aluminum and zinc and alloys thereof, is the first application of thermal spray materials, which are used to melt first wire spraying. There is also a powder material appearing after powder formula coating method appears. Aluminum and zinc are in order before the electric iron, are lively elements than iron, so they are widely used in anti-corrosion coating of steel structures, both atmospheric corrosion resistance, can be used as a sacrificial anode for steel matrix plays electric chemical protection. Foreign aluminum coating by water immersion test, to prove their good corrosion resistance to sea water, after six years of sea water samples, almost no corrosion was found. Aluminum and zinc coating, such as re-sealing treatment, the corrosion resistance will be increased. Through the introduction of the article, we know that the thermal spray zinc two requirements, quality and appearance of the coating thickness testing, as well as to know the specific content of coating material of choice. If you have any introduction of our doubts, you can communicate with us, we will in the future give us more coverage than is absolutely original article, please indicate the source if reproduced from the original link:!
