The construction process of the coating shall be in strict accordance with the specifications of the coating specification. High-viscosity thick film coatings are generally sprayed with high-pressure airless equipment. The anti-corrosion effect of the coating film obtained by high-pressure airless coating is much better than that of the coating during brushing. Therefore, Shanghai to Guiyang logistics company must choose the appropriate construction technology for certain coatings.
6. Although the auxiliary materials of the matching coating between the coating and the auxiliary material are not the main film-forming materials, they have a great influence on the curing process and coating performance of the coating.
Auxiliary materials include diluents, driers, curing agents, moisture-proof agents, defoamers from Shanghai to Bijie Logistics, plasticizers, and leveling agents. Their role is mainly to improve the coating performance and coating performance, to prevent coating defects, but they must be used properly, otherwise it will have adverse effects. For example, each type of coating has its own specific diluent and cannot be used indiscriminately. When nitrocellulose lacquer is used as a chloro lacquer, the perchloroethylene resin will be precipitated, while the amine cured epoxy will be used as an ester. When the solvent is used as a diluent, the curing speed of the coating film will be significantly reduced.
Affect the film properties. Therefore, the use of various auxiliary materials must be cautious and must not be used at will.
Third, large port machinery and equipment steel structure commonly used coatings
Large-scale port machinery and equipment investment is huge, ranging from a few million yuan, and Shanghai to Liupanshui logistics company is tens of millions of yuan. After being put into use, it is not easy to carry out maintenance and painting. Because large-scale equipment is a key equipment for production, it is often difficult to arrange for maintenance and shutdown. The maintenance of the equipment on the shore of the dock will also affect the use of berths, ranging from 20 to 30 m and 60 to 70 m. Again,
Due to the large equipment and poor construction conditions on site, it is difficult to achieve satisfactory renewal coating. Therefore, the initial coating of the equipment has been paid more and more attention. It is expected that the service life of the coating will become higher and higher, requiring a coating life of more than 10 years and a short period of not less than 5 years. During this period, the equipment steel structure does not require any maintenance coating.
