&, product uses and performance characteristics
Epoxy acid-resistant and anti-corrosion coating is composed of epoxy resin, coal tar pitch, anti-rust and acid-resistant pigments, fillers and curing agents. Acid-resistant and anti-corrosion special coating developed by our institute for ship anti-corrosion. After years of laboratory testing and five years of actual ship testing, this coating has proven to be excellent in resistance to various chemical media such as acids, alkalis, and salts. It is the latest achievement in anti-corrosion coatings for chemical equipment.
It is suitable for anti-corrosion protection in acidic environments such as ship battery compartments. It can also be used for waterline parts of ships, underwater cables and steel structure primers with alternating dry and wet operations, as well as sluices and waterways in water conservancy projects. Anti-corrosion protection of water pipes and corrosion protection of various chemical equipment.
, paint composition: (divided into base paint and top coat, each paint is composed of two components, A and B)
Bottom paint component A (brown-black liquid) component B (brown Liquid)
Top coating component A (white or gray liquid), component B (brown liquid)
, dosage ratio and packaging
The ratio of each component of the paint is based on research Compare with a large number of experiments to select the optimal dosage ratio. For convenience of use, the products are packaged in proportion when leaving the factory.
Topcoat (white or gray)
Part A (Iron barrel)
Group B (plastic barrel)

, construction method
) < br/>Bottom surface treatment
In order to improve the anti-corrosion effect of the coating, the painter should remove the residual paint film, rust, oil, scale and debris on the surface of the base material.
)
Specific requirements
Use shot blasting or sand blasting to remove rust, and the quality should reach level (B&).
If manual rust removal is used, the quality should reach grade (B&).
Before painting, oil, dust and other impurities on the surface should be removed. The cleaned steel plate should be painted in time to prevent it from rusting again.
)
Preparing paint
If the paint is left for too long, it may settle. Stir it thoroughly before use.
After opening the bucket and stirring evenly, pour component B (small bucket) into component A (large bucket) and mix evenly before use.
When the dosage is small, it can be prepared according to the proportion of components A and B.

Painting
Painting
Can be applied by brushing, roller coating or spraying. Try to make the coating evenly thin and thick, without leakage or sagging, and reach the specified thickness. It can be applied every other coat under normal temperature conditions.

After each painting, the paint brush and other construction tools should be cleaned with thinner in time to prepare for next use. If spraying is used, it is even more necessary to clean the spray and hose with thinner in time to prevent clogging after the paint solidifies.
, Precautions
) Paint contains organic solvents. At the construction site, ventilation should be paid attention to. Open flames are strictly prohibited, and explosion-proof lights must be used for lighting.
) Please store paint in a cool, ventilated and dry place.
) Wear a protective mask when working, and the working time should not be too long.
