    3. Quality inspection of anticorrosive coating

    After the coating is cured, all defects shall be inspected.

    (2) appearance inspection.

    1) visual inspection.

    2) the surface of anti-corrosion coating shall be flat, smooth and free of leakage.

    1. The thickness of coating film should be uniform.

    2. No wrinkle, drop and blister.

    3. The color distribution is consistent

    4. Good adhesion and clean appearance.

    5. The construction site is well maintained.

    6. Party A's facilities are free from abuse and damage.

    V. painting operation procedures:

    1. Before work, carefully check the painting equipment, Polish auxiliary materials, safety rope and safety belt for damage. Ensure that the performance of the equipment is good, and the same kind of equipment can be used.

    2. Construction personnel must wear work clothes before work, fasten safety belt and safety lock (on safety rope).

    3. The upper and lower temporary nurses should stick to each construction site at the same time, earnestly perform their duties, pay attention to potential safety hazards at any time, and timely report any problems found.

    4. Safe operation, civilized construction, no laughing, fighting, to ensure the quality of engineering service.

    5. It is not allowed to take the goods of Party A's customers without permission, and shall not damage the facilities of the four parties or customers.

    6. High altitude operation personnel and on-site supervisors must obey the unified command and management of the construction director.

    Paint introduction:

    1. Color steel tile primer: Alkyd iron red primer;

    Composition: refined dry vegetable oil, modified alkyd resin, iron oxide red, etc
