Problems solved by technology
Alcohol-soluble inorganic zinc silicate paint has excellent corrosion resistance and long-term weather resistance, and has excellent performance in oil resistance, salt water resistance and fresh water resistance, but its construction performance is not good. If the construction method is improper, it is easy to crack after curing, affecting coating adhesion
Because this ship type is the first ship type, this kind of paint is used in a wide range of parts and a large amount. At present, there is no specific process and standard process for the construction of alcohol-soluble inorganic zinc silicate paint for this ship type in the market.

Abstract
The invention discloses a construction method for alcohol-soluble inorganic zinc silicate paint for a G4 type container roll-on-roll-off ship. The construction method comprises the following steps: step 1, performing sectionalized oil-removal cleaning before construction; step 2, performing paint spraying on a cleaned to-be-sprayed part; step 3, uniformly mixing host and zinc powder; step 4, performing spraying operation under an RH environment with a temperature of 0-40 DEG C and humidity of 50-85%; step 5, adopting a spraying mode of pre-coating during spraying for a complex structure in a spraying process; step 6, adopting a paint wet film card to detect in the spraying process; step 7, paying attention to watering after carrier spraying is completed until alcohol-soluble inorganic zincsilicate is completely cured; step 8, performing an MEK test 48 hours after spraying alcohol-soluble inorganic zinc silicate, wherein a curing condition is good if the tested results are level IV andlevel V, and a curing condition is not good if the rested results are levels I to III. The construction method effectively controls a sprayed coating by setting an alcohol-soluble inorganic zinc silicate paint spraying pump and related pressure parameters.
Description
technical field [0001] The invention belongs to the field of ship paint construction, and in particular relates to a construction method of alcohol-soluble inorganic zinc silicate paint for G4 type rolling boats. Background technique [0002] The G4 type ro-ro ship is the world's first 45,000-ton container ro-ro ship, with a total length of 296 meters, a molded width of 37.6 meters, a molded depth of 22.95 meters, a design draft of 10.25 meters, a design speed of 18 knots, and a total of 7 car ro-ro decks. The car deck covers an area of 28,900 square meters, and the maximum number of containers it can carry is 3,800 TEUs. During the construction of this type of ship, alcohol-soluble inorganic zinc silicate paint is used for the construction of areas involving the outer plate freeboard, guide rail frame, hatch cover and ro-ro deck. Alcohol-soluble inorganic zinc silicate paint has excellent corrosion resistance and long-term weather resistance, and has excellent oil resist...
