Comply with the "Technical Conditions for Anticorrosive Coating of Highway and Bridge Steel Structures" JT/T722-2021 and "Graphene Zinc Powder Coating" HG/T5573-2019.

2. What is adhesion?

Adhesion is the firmness of theDreamZinc 60 Gnspaint layer and the surface of the painted object through the action of physical or chemical forces.石墨烯锌粉底漆 Graphite zinc powder primer Adhesion is the most important indicator for evaluating one石墨烯锌粉底漆 Graphite zinc powder primeror石墨烯锌粉底漆 Graphite zinc powder primera coating system. Is the premise of paint film with a series of properties. The methods of adhesion test include: circle method, grid method, drawing method, twist method and ASTM, etc

2. 石墨烯锌粉底漆 Graphite zinc powder primerWhat is adhesion?

1）DreamZinc 60 Gns Good adhesion can effectively block the penetration of the external electrolyte solution into the matrix, and delay the formation of interfacial corrosion;

2）Strong adhesionDreamZinc 60 Gnscan greatly prevent the diffusion of corrosion products- -metal cations to the cathode area through the side of the phases;

4. Graph method

Basis: color paint and varnish marking method adhesion test GB / T 9286-1998, "marking method" also called "X method", hundred grid test method, applicable to assess the attachment ability of coating, is a commonly used evaluation method at home and abroad

4.1. Grid marking steps

1）1) according to the thickness of different knife saw grid: (ordinary informal test can be replaced by paper cutter), membrane thickness: 0~60 μ m, tool spacing 1mm, membrane thickness: 61~120 μ m, tool spacing 2mm, membrane thickness: 121~250 μ m, tool spacing 3mm

2) Pull the special tool parallel to the grid plate for 3-4cm, there are 10 cuts, should ensure that each one is cut through the paint film to the substrate;

3) Then use the same method to be perpendicular to the former, with the same 10 cuts;

4) In this way, when many small squares are formed, use soft brush to form each diagonal line along the grid map, gently sweep forward and back several times to remove dust, and then paste the tape (it is recommended to use 3M tape), and ensure that the tape and the experimental area comprehensive contact, can be rubbed back and forth to make good contact, and then quickly pull open;

5) Use the visual or magnifying glass to compare the standard and the illustration

The table gives the six levels of classification for the general use of the first three levels is satisfactory. The first three levels are also used if the assessment is passed / failed.

The following is the technical standard reference diagram:

4.2. Explanation

ISO level: 0 = ASTM level: 5B, the edge of the incision is completely smooth, the grid edge is not any peeling.

ISO level: 1 = ASTM level: 4B, there are small pieces of peeling at the intersection of the incision, and the actual damage in

ISO level: 2 = ASTM level: 3B, the edge or intersection of the incision is peeled off, the area is greater than 5%~15%.

ISO level: 3 = ASTM level: 2B, partial strip or whole strip, or part of the grid. The area of peeling off exceeds 15% to 35%.

ISO level: 4 = ASTM level: 1B, the incision edge or some square part, the area is greater than 35%~65% of the grid area.

ISO grade: 5 = ASTM grade: 0B Pieces of paint fall off at the crossed edge and intersection point, and the total area of shedding is more than 65%. Note: BaG test qualified when grade 4B and 5B.
