Ship coating mainly refers to the steel surface treatment and paint coating operations of the hull structure and various types of outfitting parts. When building a ship, it is important to control the coating of the ship. In fact, the coating of ships is also easy to ignore. The quality of coating control has a major relationship with the safe and stable operation of ships. With the improvement of coating and painting level and the extension of ship’s life cycle, people pay more attention to the impact of the selection and construction quality of ship coatings on ship construction and future use, such as ship’s safety performance, speed, maintenance cycle and cost, and overall use Life span etc.
Ship painting is one of the important contents of ship design. Painting process conditions, rust removal quality, paint type and coating thickness are several factors that affect the life of the coating. It is necessary to ensure the quality of the pre-treated steel before coating to ensure the coating performance. Derusting of ships is actually the basic process of painting ships. Only a good treatment of the steel surface can guarantee the effect of predictive protection.
For large ships, the rust removal level is at least Sa2.5. After the rust removal is completed and the surface treatment inspection is qualified, the environmental control standards must be strictly implemented. The primer must be painted within 4 hours, and the painted surface should be protected before painting. , To prevent secondary pollution. Degaojie's hull rust removal robot adopts imported high-performance ultra-high pressure pumping station, which has high working efficiency. The paint removal efficiency can reach 50~70 m²/h, the rust removal is uniform, the operation is simple and convenient, and the operation is safer. After the coating is peeled off, the whiteness of Sa2.5 on the sandblasted surface of the steel plate can be restored.
Degaojie's ship rust removal robot is easy to operate remotely and has a high degree of automation. It combines ultra-high pressure water jet rust removal, vacuum system adsorption and slag removal, and wall-climbing robot operation. It can be controlled by the ground operator's handheld controller. The rust robot walks freely in X and Y directions on the hull's outer elevation. The rust slag and waste water generated in the process of rust removal can also be recycled and discharged to achieve the purpose of reducing emissions, recycling and environmental protection, solving the environmental protection problem of ship rust removal, improving the working environment and reducing environmental pollution.
The rust removal level needs to meet the relevant design specifications and requirements. During the process of coating the hull plate, it is necessary to ensure that the coating can evenly cover the surface of the plate that needs to be painted. With the development of large ships and long-term maintenance cycles, the design starting point of ship painting is still to solve the problem that the ship must achieve good (owner’s needs) anti-corrosion and anti-fouling properties. For ships with appearance requirements, decoration should also be considered. .
Protection function: protect metal, wood, stone, plastic and other objects from being corroded by light, rain, dew, hydration and various media. The use of paint to cover objects is one of the convenient protection methods, which can protect objects and extend their service life.
Decorative effect: Paint coating can make the object "put on" a beautiful coat, which has brilliance, luster and smoothness. The beautified environment and objects make people feel beautiful and comfortable.
Special function: After applying special paint on the object, the surface of the object can be fireproof, waterproof, antifouling, temperature display, heat preservation, stealth, conductivity, insecticide, sterilization, luminescence and reflection functions.
