With the development of high-solids, solvent-free coatings products, with the development and application of high-tech paint products, the selection of suitable anti-corrosion coatings can reduce the coating cost and increase the life of the coating, thereby significantly reducing the investment cost of anti-corrosion treatment.
1, reduce coating costs:
Coating costs include coating costs, painting costs, and pre-processing costs.
When considering the comparison of paint costs, the unit price of the paint is only an intuitive factor that affects the cost of the paint. The solid content (volume) is the real price of the paint. Solid volume refers to the ratio of the volume fraction of the film-forming material that can be cured in a solvent-based coating. The higher the solid volume, the wider the applicable area with the same film thickness and the proportional relationship between them. The formula can be used to calculate:
Theoretical coverage area m2/L = [solid volume (vs%) x 10] / [dry film thickness (μm)]
Note: The solid content is based on the weight, and the weight solids should be converted into solid volume when calculating.
The solid content of the coating is high, and the unit coating rate is high and the use amount of the coating can be relatively reduced. In one pass, the film thickness can be reduced, the construction pass and the painting cost can be reduced, the recoating time can be saved, and the work efficiency can be improved.
In the coating cost, the proportion of pre-processing costs is the largest. The use of conventional anti-corrosion coatings and heavy-duty coatings, because of the strict surface treatment, this pre-treatment costs more than the cost of the coating plus the sum of the painting costs, accounting for more than 60% of the coating cost, so choose a low surface treatment The high-performance anti-corrosion coating (with rust and wet coating) can save the cost of pretreatment because it only requires manual rust removal or st2-st3 level surface treatment, which is the main factor to reduce the coating cost.
2, improve the coating life
Coating life is an important factor affecting the cost of preservation. For conventional paints or heavy anti-corrosion coatings that require strict surface treatment, due to the structure of the equipment components or the construction environment during the actual use, the sand blasting is inconvenient or inadvertently causes corrosion hazard; or due to climate humidity Changes, the surface of the substrate is not easy to detect condensation or return rust, corrosion cycle soon after coating. The pre-treatment can not reach the standard, seriously affecting the life of the coating film. The large and small-scale anti-corrosion projects that require hundreds of thousands to several million yuan to be repaired each year are numerous. Many production companies also need to stop production and repair and cause the associated economic losses, and thus the equipment components. During the life-long use process, the cost of anti-corrosion directly and indirectly is very expensive.
With the development and successful application of high-performance anti-corrosion coating with rust and wet coating, the product can effectively solve the problem of residual rust or rust caused by rust, effectively solving the corrosion of the coating under various environmental conditions. Difficulties in internal problems make it easy to carry out anti-corrosion construction under various environmental conditions, and it is easy to ensure construction quality and ensure long-term anti-corrosion life of the coating. The maintenance of a year and the need for maintenance once each year can save a huge amount of anti-corrosion treatment costs and avoid the associated economic losses caused by maintenance and production stoppages. The impact on business efficiency is very significant.
