Proprietà chiave e metodi di prova dei rivestimenti per colata
Il rivestimento per fusione è un tipo di rivestimento speciale applicato nel processo di fusione. It is mainly used for coating the surface of casting mold to protect the mold, adjust the surface quality of casting parts and improve the casting process. Casting coating has the characteristics of high temperature resistance, wear resistance and chemical corrosion resistance, and is widely used in the casting production of automobile, macchinari, electronics and other industries.

Proprietà chiave e metodi di prova dei rivestimenti per colata
Prova di viscosità: Pour the coating into the measuring cup with the viscometer to measure its motion resistance. Select the corresponding measuring conditions according to different viscometer models and paint types for testing.
Rheological testing: The rheometer is used to test the dynamic rheological properties of coatings, understand their rheological properties and rheological laws, and select the appropriate rheometer testing conditions according to different types and application scenarios of coatings.
Rilevamento del contenuto solido: Paint is coated on a well-weighed drying pan, put in the oven, dry at a certain temperature and time, weigh the weight of the drying pan and paint, and calculate the solid content of the paint.
Rilevamento del tempo di asciugatura: Paint evenly on the test board, placed at room temperature for natural drying, according to the different types and thickness of the coating to determine the different drying time, use room temperature timer to record the drying time.
Prova di resistenza al calore: The thermogravimetric analyzer is used to heat the paint at high temperature to understand its thermal stability and heat resistance, and the corresponding test conditions are selected according to different paint types and application scenarios.
Corrosion resistance detection: Use the corrosion tester to carry out corrosion test on the coating, understand its corrosion resistance, and select the corresponding test conditions according to different corrosion test methods and coating types.
