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.
