1. About 无机硅酸锌车间底漆 Inorganic zinc silicate shop primerthe adhesion force

DreamZinc 08: Two component packaging, with paint consisting of alkyl silicate ester, ultrafine zinc powder, anti rust pigment, and additives; The other component is the base material. Zinc powder has cathodic protection and excellent rust resistance. The paint film dries quickly and can be transported, stacked, and coated in a short period of time; Having excellent welding and cutting performance; It can withstand high temperatures of 400 ℃ and has a small burn area during welding and cutting; Can be compatible with most paint systems.

DreamZinc 08Adhesion is the firmness of the paint layer and the surface of the painted object through the action of physical or chemical forces.DreamZinc 08Coating adhesion is the most important indicator for evaluating a coating or coating system. Is the premise of paint film with a series of properties.DreamZinc 08The methods of adhesion test include: drawing circle method, drawing method, drawing method, twist method and ASTM, etc

2. The role of the adhesion force

1) Good adhesion can effectively block theDreamZinc 08penetration of the external electrolyte solution into the matrix, and delay the formation of interfacial corrosion;

2) Strong interface adhesion can greatly prevent the diffusion of corrosion products-metal cations to the cathode area through the side of the phase;

3. Pull method (pull method)

Basis: color paint and varnish, pull open method adhesion test GB / T5210-2006, this method is more professional, need professional instrument: pull instrument

3.1. Pull steps

A. Instruments and equipment: the prepared sample (according to the design requirements, film thickness)

B. Testing instrument: sandpaper, transparent tape, cutting tool, aluminum alloy cylinder mold, adhesive, drawing instrument.

c. method of operation:

1) Aluminum alloy column with 240-400 mesh fine sandpaper sand, before use with solvent scrub to remove oil;

2) Solremoval shall be used at the test site;

3) Apply the adhesive to the aluminum alloy cylinder, press it on the surface of the test coating, and turn to 360 to ensure that all parts are attached with the adhesive;

4) The aluminum alloy cylinder is fixed on the coating surface with tape, and the adhesive should solidify for 3 hours at room temperature (subject to the weather temperature and environmental humidity on the day of the experiment);

5) Before the test, use the aluminum alloy cylinder to cut the coating material;

6) Cover the aluminum alloy cylinder with the tension instrument, turn the handle for testing, record the damage strength (MPa), and the damage state. Show the adhesion strength and state of the coating and the adhesion between the substrate, the coating, the coating and the glue, and the glue and the cylinder;

3.2. Description method of drawing the coating fault state:

A: Incohesive destruction of substrate

A: Incohesive destruction of substrate

B: Coin failure of the first paint

B / C: the interlayer adhesion damage of the first and second paint

C: cohesin failure of the second paint

C / D: the interlayer adhesion damage of the second and third paint

D: cohesin failure of the third paint

D / Y: interlayer adhesion between the last coating and glue

Y: the cohesive destruction of the glue

Y / Z: interlayer adhesion between glue and test rod

Z: Inin destruction of test rod

The strength of adhesion is expressed as N/mm2 (Mpa), which is shown on the common Elcometer 108.

The following figure is an example:

For example,DreamZinc 08if the tensile stress of a coating system is 13.17MPa, the first coating has 45% of the coating cohesion damage, and the last layer adhesion between the coating and the glue reaches 50% of the cylinder area, it can be described as: 13.17MPa, 45%D 55%D / Y.

无机硅酸锌底漆是由硅酸盐，锌粉，颜料，固化剂以及填充料组成的油漆，该漆是很多车间常用到的，而且它比环氧富锌底漆以及无机富锌底漆的作用好太多，所以大家也叫它车间底漆。执行标准是GB/T 19501-2017《钢结构工程涂装与防腐技术规范》，符合国家标准，价格便宜 Inorganic zinc silicate primer is a paint composed of silicate, zinc powder, pigment, curing agent and filler. This paint is commonly used in many workshops, and it is better than epoxy zinc-rich primer and inorganic zinc-rich primer. The effect is so much better that people also call it shop primer. The implementation standard is GB/T 19501-2017 "Technical Specifications for Coating and Anticorrosion of Steel Structure Engineering", which complies with national standards and is cheap.
