Do you know the commonly used paint detection and analysis?

Q: What are the types of coatings?

Answer: According to the form, it can be divided into solid coatings and liquid coatings; according to the use, it can be divided into industrial coatings and civil coatings, and industrial coatings can be divided into color board coatings, automotive coatings, architectural coatings, wood coatings, aircraft skin coatings, etc.

Q: What is the purpose of paint analysis testing?

Answer: The performance of the coating determines the quality of the coating and the use of the coating, and the performance of the coating is multi-faceted

Q: What is the significance of coating performance testing?

A: The analysis and testing of coatings is an indispensable and important link in the production and use of coatings, the main basis for formulating technical indicators of coating products, and a specific method for evaluating the performance and quality of coatings

1.

Q: What are the commonly used technical indicators for coating analysis and testing?

Answer: The indicators of the physical state of the coating include density, viscosity, etc.

Q: What is film hardness?

Answer: The hardness of the coating film refers to the firmness of the coating film after drying, which is used to judge the degree of damage to it when it is subjected to external friction and collision

Q: What are the coating adhesion test methods?

Answer: The adhesion of the coating film refers to its ability to firmly bond with the surface of the object to be coated
.
Products with poor adhesion are easily peeled off from the surface and lose their protective and decorative effects
.
Adhesion measurement methods include circle method, cross-cut method, torsion method, scratch method, tape adhesion method and peeling test method
.

The cross-hatch method is a test method for assessing the resistance of a coating to release from a substrate when the coating is cut in a grid pattern at right angles to penetrate the substrate
.
The adhesion force measured by the pull-off strength method refers to the force required to apply a vertical uniform tensile force on the cemented surface of the sample at a specified speed to measure the adhesion failure between coatings or between coatings and substrates
.

Q: What are the common coating test standards?

Answer: Different countries have different test standards and requirements, the common ones are ISO, STM, GB, JIS and other standards
.
For example: common standards for hardness testing are: ASTM D3363, ISO 15184, GB/T 6739, JIS K5600-5-4; common standards for thickness testing are: ASTM D7091, ASTM D1186, ISO 2808, ISO 2360; impact resistance test Common standards are: ASTM D2794, ISO 6272, GB/T 20624, JIS K5600
