When the coating of large galvanized wire is blistered in the process of galvanizing, the bath temperature should be checked first. If the bath temperature is not low, and then strengthen the removal of oil before plating, to prevent the base metal in acid corrosion. If you pay attention to these problems, the bubbling phenomenon still exists, it should pay attention to the dosage and quality of additives, then you can stop adding additives, with high current electrolysis for a period of time, to reduce the content of additives, observe whether the bubbling phenomenon is improved. If there is no improvement, check whether the additive has been stored for too long or whether it contains too many impurities.

The characteristics of galvanized hexagonal net: easy to use; Save transportation costs. It can be shrunk into small rolls and involved in moisture-proof paper packaging, taking up little space. Coating thickness uniformity, stronger corrosion resistance; The construction is simple and does not require special technology; Strong resistance to natural damage and corrosion resistance and adverse weather effects; Can withstand a large range of deformation, and still not collapse. It has the function of fixed heat preservation and insulation.

After the corrosion of impregnated hexagonal wire mesh, the original characteristics will be lost, and the shape, color and mechanical properties will be changed, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated six-sided wire mesh, prolong the service life of the product.
