Machine tool coating is a special industrial coating, which is mainly used for protective coating such as anti-corrosion, anti-rust and anti-corrosion on the surface of machine tools. Machine tool coatings are usually made of high-performance materials such as silicone coatings, phenolic coatings, polyurethane coatings, and epoxy coatings. They have strong durability, corrosion resistance, and wear resistance, which can effectively protect the surface of machine tools and prolong the service life of machine tools. Machine tool coatings not only have a protective effect, but also improve the aesthetics and ease of cleaning of the machine tool surface. It is an indispensable coating in the field of machining and manufacturing.
Machine tool coating detection performance
| performance | Test items |
|---|---|
| solid content | Solids content of paint |
| drying time | coating drying time |
| Corrosion resistance | Corrosion resistance |
| wear resistance | Anti-wear performance |
| Adhesion | The degree of bonding between the coating and the substrate |
| Gloss | Gloss of the coating surface |
| density | Coating density |
| chemical resistance | Acid and alkali resistance, solvent resistance, etc. |
| Temperature resistance | High temperature performance |
| other | Such as color fastness, viscosity, pH value, etc. |
The results of these test items can help evaluate the quality and suitability of machine tool coatings and how they will perform in real-world applications. The test methods and equipment vary according to the specific machine tool coating types and test items.
Common detection methods for machine tool coatings:
Solid content: Use oven drying method, centrifugation method and other methods to test the solid content in the coating.
Drying time: Use a device such as a drying time Tester to measure how long it takes for the coating to dry.
Corrosion resistance: The corrosion resistance of the coating is tested by salt spray test, acid-base corrosion test and other methods.
Abrasion resistance: Use grinding wheel abrasion test, pencil hardness test and other methods to test the anti-abrasion performance of the coating.
Adhesion: The degree of bonding between the coating and the substrate is tested by cross-hatch method, peeling method, tensile method and other methods.
Gloss: Use a gloss meter and other equipment to test the gloss of the coating surface.
Density: Measure the density of the coating using an instrument such as a densitometer.
Chemical resistance: Use acidity meter, alkalinity meter, solvent immersion and other methods to test the acid and alkali resistance and solvent resistance of the coating.
Temperature resistance: test the high temperature resistance of the coating through oven high temperature test, constant temperature and humidity test and other methods.
Others: According to the specific machine tool coating types and testing items, select appropriate testing methods and equipment for testing, such as measuring the color fastness, viscosity, pH value, etc. of the coating.
NBCHAO reminds you: The performance test of machine tool coatings needs to be carried out in accordance with relevant standards and methods to ensure the accuracy and comparability of test results.
