NANO COMPOSITE COATING IN SHIP BUILDING MATERIALS

INFLUENCE OF NANO COMPOSITE COATING IN SHIP BUILDING MATERIAL

KAVITHAYENI.V115012305001

OBJECTIVE

You can replace this sample textNano composite coating provides more mechanical strength with light weight to the materials.

1

The main objective is to prevent the oil leakage in seas after accident occurs.2

TIMELINE

CONVENTIONAL COATING MERITS AND DEMERTIS

1 Doesn't resist to alkaline greater than pH 9 and acids less than pH 6.

2 Fouling and antifouling coating corrodes when overly expose to nature.

3 zinc silicate gives life time of maximum 30 years.

4 Epoxy coatings generally possess a good resistance against alkalis.

MATERIAL WE PREFER

• Due to their unique physical property and one more thing is, this is a composite material, which can also be sticked to the materials easily.

CF AEROGEL

• A mineral package as the capability of purifying the metal electroplating wastes and also in wastes water treatment.

ZEOLITE

PROPERTIES OF CARBON FIBER AEROGEL

1 Low apparent density of ca10 mg cm−3,.

2 The high porosity is in accordance with SEM and TEM observations

3 It can support a weight of at least 500 g even though the aerogel itself weighs only 56.1 mg.

4 The maximum compressive stress is up to 85 kPa before fracture.

PROPERTIES OF ZEOLITE

• Oil absorption media is a mixture of anthracite and modified zeolite or clay, mixed with anthracite in a 70:30 ratio of anthracite to active ingredient. Thus, the capacity for oil ranges from 60-90% of the total weight of the media.

• Maximum flow velocity into a unit is 5 gpm/ft2. Also have the capability of removing arsenic from water and other organic compounds gives toxic to the water.

• The foremost thing to note is zeolite is a mineral which can be easily used for coating.

CONCLUSION

This concept will establish a new revolution in the marine field.

It’s cost efficient too. And gives more life time to the ships.
