Film forming mechanism of color coated steel coil
The coating film formation of color coated plate mainly includes coating adhesion and coating drying. A Color coated plate coating adhesion The first step of the adhesion of the steel strip substrate and the coating is the wetting of the color coated plate coating on the surface of the substrate....Read more -
Why does galvanized sheet rust?
Why does galvanized sheet rust? The zinc is corroded normally, otherwise it means that the zinc plate is impure and contains impurities, such as iron. Zinc protects other metals. Uneven zinc coating will expose the metal inside and cause corrosion. Or inadvertently contact with other metals to fo...Read more -
Standard practice for construction of geogrid in subgrade engineering
Construction process flow Construction preparation (material transportation and setting out) → base treatment (cleaning) → geogrid laying (laying method, overlapping width) → filler (method, particle size) → roll up the lattice → lower grid laying Build. Construction steps 1、 Foundation treatmen...Read more -
Classification of galvanized sheet according to production and processing methods
Classification of galvanized sheet according to production and processing methods ① Hot-dip galvanized steel sheet. The thin steel plate is immersed in the molten zinc bath to make its surface adhere to a layer of zinc. At present, it is mainly produced by continuous galvanizing process, that is,...Read more -
Storage time and precautions of galvanized steel coil
Although the galvanized sheet has good corrosion resistance and the galvanized layer is relatively thick, even if it is used outdoors for a long time, rust and other problems can also be avoided. However, many purchasers purchase steel plates in batches at one time, which may not be put into use ...Read more -
Influence of short fiber content of geotextile on dry and wet state
With the increase of PVA content in geotextile, the dry strength and wet strength of mixed geotextile have been greatly improved. The dry/wet breaking strength of pure polypropylene geotextile is 17.2 and 13.5kN/m respectively. Influence of short fiber content of 400g/m2 geotextile on dry and wet...Read more -
Welding of galvanized coil
The existence of zinc layer has brought some difficulties to the welding of galvanized steel. The main problems are: the increased sensitivity of welding cracks and pores, zinc evaporation and smoke, oxide slag inclusion, and the melting and damage of zinc coating. Among them, welding crack, air ...Read more
