Proprietățile cheie ale acoperirii bobinei și metoda de detectare a acesteia
Un strat de bobină este o acoperire aplicată pe suprafața unei bobine sau a unui material film, usually consisting of polymers, pigmenti, and additives. They can be applied in many different fields, such as building roofing, insulating materials, auto, and aviation, among others. Coil coatings have good water resistance, weather resistance and UV resistance, which can improve the service life and performance of materials.

Etapa de detectare
Grosime: Use a thickness gauge to measure the thickness of the coil coating, record the measured value and calculate the average value.
Viscozitate: Use a viscometer to measure the viscosity of the coil coating, record the measured value and calculate the average value.
Tensile strength and elongation at break: tensile tests were carried out using a tensile testing machine, test data were recorded and tensile strength and elongation at break were calculated.
Rezistenta la apa: Place the coil coating in water using a water circulation device, record the time and observe the change of the coating.

Weather resistance and UV resistance: use UV aging test chamber to simulate solar radiation and atmospheric environment, observe the changes of coil coating.
Bond strength: Shear tests were performed using a shear strength tester, test data were recorded and bond strength was calculated.
Expansion coefficient: The expansion coefficient of the coil coating was measured using a thermal expansion coefficient tester, and the measured value was recorded and the average value was calculated.
