The coating industry has a lot of "derailment" benefits

The quality of products is the life of an enterprise. Good shipbuilding quality is an important condition for ensuring safe navigation and operation of ships. Sea voyages, seawater erosion, and sun exposure all require good ship paint support.

(1) Recoatable polyurethane hull paint recoatability test results show that: the destruction of the site is mostly recoated paint film damage, indicating that this part is the area of ​​paint recoatability should pay special attention to the area. The test also showed that the recoatable polyurethane paint after accelerated curing by heat, 6 months, 12 months of atmospheric exposure, after 200h, 500h, 1000h UV aging, the paint film adhesion strength did not significantly reduce, and the paint has been used for many years The results are consistent, and the recoating test method proposed in this paper is credible.

(2) Marine liquid tank paint recoatability tests, whether internationally ISO standards or ASTM, MIL-PRF-23236C standards, are relatively mature methods, and are evaluated at no less than 50% of the original adhesion strength. The author believes that cabin paints are best simulated aging in combination with the most demanding conditions during actual use, so that the results of indoor acceleration tests performed can be consistent with the expected effects of the actual use process.

(3) With the continuous advancement of science and technology and detection methods, detection methods are constantly improving. The recoatability test method is a new test route that has been developed with the advancement of paint technology. The test method combining the natural state and the accelerating state of the room not only can observe the difference between the two, but also can verify the overcoating performance of the coating at the same time, and has certain reference significance for the domestic detection of recoatability. There are many kinds of special paints for ships, which will continue to evolve in the future. The paint can be applied at lower temperatures and has strong adhesion. Widely used in ships, bridges, steel structures and wet tropical or chemical environment equipment, equipment protection paint, is a good protective paint.

 We have been in the research, development, sales of different pharmaceutica Intermediate and organic intermediate chemicals since our foundation, severing customs in the US, Japan, South East Asia, South America, Middle East etc.
For example, sodium bromide is used for making sensitive emulsion of photographic film and for making medicinal intermediates in medico-industries, e.g. diuretic , sedative etc. It is also used as bromide making complex material and complex dyes.Characters: Colorless cubic crystal or white granular powder.
