Factors that reduce the cost of corrosion protection in coating products

with the development of coating products towards high solids and solvent-free, with the development and application of high-tech coating products, the selection of suitable anti-corrosion coatings can reduce coating costs, improve film life, thereby greatly saving the investment costs of anti-corrosion treatment1, reduce coating costs:coating costs include coating costs, painting costs and pre-treatment costswhen considering comparing the cost of coatings, the unit price of coatings is only an intuitive factor affecting the cost of coatings, solid content (volume) is the real price of coatingsSolid volume refers to the solvent-based coating can be cured into a film material's volume portion ratio, the higher the solid volume, the same film thickness of the coating area is wider, the more proportional relationship between the formula, can be calculated:theoretical coverage area m2 /
Lpaint has a high solid content, high unit coating rate and relatively reduce the use of paint, a sub-construction into a thick film and can reduce the construction path and brushing costs, can save the time between recoating and improve efficiencythe proportion of pre-treatment costs is the largest of the coating costsThe use of conventional anti-corrosion coatings and heavy anti-corrosion coatings, due to strict surface treatment, this pretreatment costs than the cost of coating plus painting costs, about 60% of the cost of coating, so choose low-surface treatment (rust, wet coating) of high-performance anti-corrosion coating, because only manual rust removal or to reach the st2-st3 level of simple surface treatment, can significantly save the cost of pretreatment, is to reduce the cost of coating2, improve the life of coating film
coating film life is an important factor affecting the cost of corrosion protectionfor conventional coatings or heavy anti-corrosion coatings that require strict surface treatment, in the actual use process, due to the structure of the equipment components or the limitations of the construction environment conditions, sand blasting rust removal is inconvenient or inadvertently will leave corrosion risks, or due to climate humidity changes, the surface of the substrate is not easy to detect condensation or rerust, after coating also quickly produce rust cyclePre-treatment can not meet the standard, seriously affect the life of the coating film, every year need to spend hundreds of thousands to millions of dollars to carry out maintenance of the size of anti-corrosion works are numerous, many production enterprises also need to stop production and repair and cause associated economic losses, so in the equipment components in the whole life of the use of the process, direct and indirect cost of anti-corrosion is very expensivewith the development and successful application of high-performance anti-corrosion coating with rust and wet coating, the product effectively solves the problem of rust or rust return caused by rust, effectively solves the problem of water causing corrosion to the coating under various environmental conditions, makes the construction of corrosion under various environmental conditions simple and easy, easy to ensure the quality of construction, and ensure the long-lasting corrosion protection life of the coating filmMany years only once repair and the annual need for maintenance comparison, can save a huge amount of anti-corrosion treatment costs and avoid the maintenance of production stoppage caused by the associated economic losses, the impact on the benefits of enterprises is very significant
