Baked Blue Packing Belt Baked Blue Packing Belt
The surface of the regular steel belt is lubricated, which reduces the space between the steel belts and the space between the steel belts and the packaged objects during packaging. The friction resistance allows the steel belt to be tightened and the packaging to be more secure. The edge of the steel belt is smooth and has no edges and corners to avoid scratches on the packaged items during packaging.

The outside of the steel strip is packed with linen, and each package contains a coil or coil of steel strip (depending on the specific model and tied with iron bars. The material is high-quality cold-rolled plate.



, The plate surface is smooth, the zinc flowers are uniform, and the color is bright
, Galvanized strip steel has the characteristics of anti-corrosion, strong tensile performance, fire resistance, etc.
, Made of galvanized steel Strip steel is beautiful, economical and durable
. The galvanized layer has good adhesion to the steel plate, is rust-proof and durable, and does not fall off
. It is used as a raw material for a series of building materials, such as light steel keels and galvanized pipes. , fire-proof rolling shutter doors, civil materials and other industries.

Surface lubrication of steel strip reduces packing The friction resistance between the steel belts and between the steel belts and the packaged objects can be used to tighten the steel belts and make the packaging more secure. The edges of the steel belts are smooth and have no edges and corners, thus avoiding scratches on the packaged objects and scratches during packaging.
The outside of the steel strip is packed with linen, and each package contains a coil or coil of steel strip (depending on the specific model and tied with iron bars.

The impact of different galvanizing methods on packing tapes
Hot-dip Because the zinc strapping strip is produced on a hot-dip galvanizing line, through continuous annealing and continuous hot-dip zinc liquid, the steel plate is heated and cooled in a short time, so its stamping performance is worse than that of the cold-rolled original plate.
Electroplating Since the zinc packing belt is not affected by heating, cooling and other temperatures during the electroplating process, it has roughly the same stamping performance as the cold-rolled original plate. There is no fragile iron-zinc alloy layer in the galvanized layer, and the expansion of the galvanized layer It has good performance, but due to its porous surface and low strength, it is easy to be scratched and contaminated by dry paint.
Causes of indoor corrosion
The result of the corrosion of the zinc layer of galvanized strapping is the formation of white iron , has a great impact on the physical and chemical properties of the strapping. The reason why the zinc layer of galvanized strapping corrodes indoors
is that the indoor air humidity is high
and the finished product is not dried before being stored
, there is a layer of water film condensed on the surface of the zinc layer. When the moisture content in the air reaches or within the range of ~, and the corrosion reaction is more violent. When the water temperature reaches about ℃, it corrodes the zinc layer the fastest.
Stacking site requirements
When galvanized packing straps are stacked, there should be no condensation on the surface
Air circulation should be maintained in the warehouse, and the relative humidity of the air should not be within the range of or ~
/> , Galvanized strapping should not be stacked with harmful gases and excessive dust
