Galvanizing has started some 300 years ago when
an alchemist-cum-chemist dreamt up a reason to
immerse clean iron into molten zinc and to his
amazement, a shimmering silver coating developed
onto the iron. This was to become the first step
in the genesis of the galvanizing process.
Ornaments made from alloys that contain 80
Zinc, brass (an alloy of copper and zinc) has
been traced at least 10th century B.C. these
things are the evident that Zinc is closely
interlined with that of the history of
galvanizing.

Galvanizing Today Galvanized steel is all around
us and plays a vital role in our everyday lives.
It is used in construction, transport,
agriculture, power transmission and everywhere
that good corrosion protection and long life are
essential. It, for instance, helps light our
roads and provide power for our homes, hospitals
and offices. There are many other important
industries that make use of galvanizing. Recent
reductions in the aggressiveness of the
atmosphere towards Zinc, and the stability of
costs of applying the coating mean that hot dip
galvanizing today costs less and lasts longer.
Zinc the essential raw material for hot dip
galvanizing is a highly recyclable metal which
is vital for human health and ecosystems.
Advancements in metallurgy and furnace technology
have improved process efficiency and the
sustainable credentials of galvanizing.

What Makes Hot Dip Galvanizing A Popular Activity
Over Cold Galvanizing?
Hot dip galvanizing is the ingot melted at high
temperatures, a number of supplementary materials
in place, then dipped galvanized metal structure
slot, the metal component on a layer of zinc
coating. The advantages of hot dip galvanizing
corrosion of his ability, adhesion, and hardness
of zinc coating is better. On the other hand,
cold galvanizing include zinc salt solution by
electrolysis to the plating on the coating that
generally dont have heating, small amount of
zinc, the wet environment is very easy to fall
off. Hot dip galvanizing is a chemical treatment
where electrochemical reaction takes place. On
the contrary, cold galvanizing is the physical
address, just brush the surface layer of zinc,
the zinc layer is easy to fall off. Construction
in the use of hot dip galvanizing process follows
the pre-defined work process. Hot dip galvanized
steel body is hot dip galvanized surface under
the condition of its adhesion strong, not easy to
fall off, although there hot dip galvanized pipe
corrosion phenomenon but in a very long period to
meet technical, health requirements.

Technical Differences between Hot Dip Galvanizing
and Cold Galvanizing
First of all, is the difference between
processes hot dip galvanizing is the work piece
degreasing, picking, dipping, drying liquid
immersion in molten zinc certain period of time,
can be raised. Cold galvanizing on the other hand
is to use electrolysis devices work piece through
the degreasing, pickling ingredients post into
the zinc salt solution and connect the anode
electrolysis equipment in place across parts of
zinc plate connected to the electrolysis
equipment positive, power on, use of current from
the cathode to the anode of the directional
movement of the work piece will be deposited in a
layer of zinc. Zinc finished the difference no
cold galvanized hot dip galvanizing delicate
bright appearance, but the thickness of zinc
coating of cold galvanizing aspects of hot dip
galvanizing is a few times. Galvanized corrosion
resistance is also several times.

Technical Differences between Hot Dip Galvanizing
and Cold Galvanizing
Environmental Issues Hot dip galvanizing
equipment ensures fewer emissions. Galvanized
pollutants are mainly artifacts of waste acid
pickling. Cold galvanized pollutants include
parts of the waste acid pickling, electroplating
waste, and liquid waste such as passivation. Cold
galvanized the type and quantity of pollutants
discharged are much more than hot dip galvanizing
equipment. Hot dip galvanizing process is
generally completed after hemming when the load
is not less than 5mm thick flat steel, the
galvanized zinc coating after the average weight
of not less than 610grams/sq. meter when the load
flat steel thickness less than 5mm, the
galvanized zinc coating after the average weight
of not less than 460grams/square meter, and after
galvanizing quality requirements should be
consistent with the provisions GB/T13912.

Technical Differences between Hot Dip Galvanizing
and Cold Galvanizing
Shanghai Bonan Technology has a long standing
tradition in implementing hot dip galvanizing
equipment in the specific market which allows
providing highly productive installations and
superlative finished product quality. Our
manufactured and supplied hot dip galvanizing
equipment is capable of quickly reaching
unprecedented basket acceleration just outside
the zinc, right on top of the zinc bath. The
first ensuring advantage is certainly a much more
efficient spinning process, as this happens when
zinc is still quite fluid and at high
temperature. Shanghai Bonan Technology, being
the best in industry Hot Dip Galvanizing
Equipment Company, aims as usual at achieving
great product quality for the customer,
effectiveness and easiness in the galvanizing
process, while ensuring efficiency and cost
cutting. Trust our team to enter a new dimension
in hot dip galvanizing.
