Abstract
The invention discloses a type selection method of a low-temperature and anti-corrosion coating on the outer surface of a liquid tank of a gas transportation ship. The type selection method comprises the steps of selecting a paint system, preparing testing plates, treating the surfaces, measuring the thickness of a dry film of each plate and carrying out heat circulation test and the like. The type selection method is simple and is good in effect; the coating layer is tested by simulating a high-low temperature alternation test of the working temperature of LPG/LEG/LNG gas transportation ship, and the matching of two coating layers with combination of workshop primer and economic type pure epoxy primer can be achieved.
Description
Technical field
The present invention relates to the selection method of the low temperature resistant anticorrosive paint of a kind of gascarrier flow container outside surface.
Background technology
Current shipbuilding industry flow container market, low temperature resistant anticorrosive paint exceedes one or two of the international well-known coating manufacturer of Jin You of subzero 100 degrees Celsius, the low-temperature resistant coating that other producer has is all to provide third-party certificate, domestic paint manufacturer is substantially not qualified, the low temperature resistant anticorrosive paint that this only surplus a few family has the manufacturer of certificate to provide with general domestic shop primer compatibility issue on do not do experiment yet, the infrastructure condition that workability more reckons without general shipyard fails to play easy construction, effect with low cost.
Summary of the invention
The object of the present invention is to provide a kind of selection method of easy, the effective low temperature resistant anticorrosive paint of gascarrier flow container outside surface.
Technical solution of the present invention is:
A selection method for the low temperature resistant anticorrosive paint of gascarrier flow container outside surface, is characterized in that: comprise the following steps:

Test plate (panel) quantity: 4
Test plate (panel) 1 and test plate (panel) 2 are constructed paint system one;
Test plate (panel) 3 and test plate (panel) 4 are constructed paint system two;
At the paint system that the positive surface construction of test plate (panel) is complete;
Construct overleaf and only do 1 degree;
(3) surface treatment,
All surface is all clean, dry and pollution-free, processes according to ISO8504:1992;
According to SSPC-SP1 code requirement, oil stain removing is clean;
Blasting treatment grade to Sa1/2 (ISO8501-1:2007), roughness 50-75u;
(4) build of every block plate
Measure and record the build of every block plate;
(5) thermal cycling test is carried out
By above-mentioned ready test plate (panel), circulate according to the cycle below;
(I) injects liquid nitrogen, stops, keeping this temperature one hour when temperature drops to subzero 165 DEG C;
(II) is recovered indoor temperature 20 DEG C-40 DEG C and is kept 1 hour;
Circulate 4 all after dates, and coating will do following test
(I) visual examination
