Information

Cold galvanized paint and high-frequency straight seam welded pipes are anticorrosive products with high zinc content, and the anticorrosive performance of the two is also outstanding. With their own product performance advantages, they have gradually developed into mainstream industrial anticorrosive products on the market today. What are the similarities and differences between the two, then follow the editor to understand the similarities and differences between the two.

1.Different zinc

Cold galvanized paint: the zinc content of the dry zinc of the cold galvanized paint reaches 96%

High frequency straight seam welded pipe: national standard zinc content has 60%, 70%, 80% three standards

Both are electrochemical anticorrosive coatings, and both can provide very good cathodic protection characteristics. Due to the different zinc content, the anticorrosive effect will be different.

2, different ingredients

Cold galvanized paint: Cold galvanized paint zinc is produced by high-purity zinc powder, solvent, auxiliary agent and other special coating technology, which belongs to one-component paint.

High-frequency straight seam welded pipe: a two-component self-drying coating consisting of medium molecular epoxy resin, special resin, zinc powder, additives, lead-free solvent, and amine curing agent.

There is a big difference in the composition of the two. From the perspective of use, cold galvanized paint is simpler, but from the perspective of market utilization, the latter is better.

3. Different construction

Cold galvanized paint: brush, roll, spray. The recommended film thickness is 80μm-100μm.

High-frequency straight seam welded pipe: a two-component self-drying paint consisting of medium-molecular epoxy resin, special resin, zinc powder, auxiliaries, and lead-free solvents. .

Both need to degrease and rust the steel surface, and sandblast the surface to achieve a surface roughness of 35μm-75μm. Because both are rich in zinc, they must be in full contact with the steel surface to play the role of zinc to achieve Better antiseptic effect.

4, different supporting

Cold galvanized paint: cold galvanized paint + cold galvanized sealant

High frequency straight seam welded pipe: high frequency straight seam welded pipe + epoxy mica iron intermediate paint + fluorocarbon paint \ high frequency straight seam welded pipe \ polysiloxane topcoat

5.Different uses

Cold galvanized paint is an excellent coating to replace the hot galvanizing process, which is suitable for the protection of power facilities, such as power plants, substations, and electrical towers.

High frequency straight seam welded pipe is widely used in metallurgical, container, various types of transportation vehicles, engineering machinery steel plate pretreatment shot blasting, especially suitable for rust prevention of steel structures, is a very good rust maintenance primer.
