Pengujian kinerja resin light curing
A photocurable resin is a polymer material whose curing process is catalyzed by a photoinitiator under ultraviolet or visible light. Light curing resin is usually a single component material, itu adalah, it only needs to be coated on the substrate, through ultraviolet or visible light irradiation, can achieve rapid curing of the coating in a few seconds or minutes. Light curing resin has excellent heat resistance, ketahanan terhadap bahan kimia, wear resistance and aging resistance, and has the advantages of low cost and easy to use, which is widely used in the coating and manufacturing process of 3D printing, elektronik, optics, printing and other fields.

The results of these test projects can help to evaluate the quality and suitability of the photocurable resin and how well it will perform in practical applications. The test method and equipment are different according to the specific type of light curing resin and the test item.
Pengujian kinerja resin light curing
Metode deteksi
Curing degree: Use microscope, infrared spectrometer and other equipment to test the curing degree of the coating.
Viskositas: Use viscometer and other instruments to measure the viscosity of the paint.
Kekerasan: Use Rockwell hardness tester, Babbitt hardness tester and other equipment to test the hardness of the coating.
Ketahanan aus: the wear resistance of the coating is tested by grinding wheel wear test and pencil hardness test.
Ketahanan terhadap bahan kimia: Use acidity meter, alkalinity meter, solvent immersion and other methods to test the acid and alkali resistance of the coating, ketahanan terhadap pelarut, dll..
Pengujian kinerja resin light curing
Transparansi: Test the transparency of the coating using equipment such as light transmitter and optical wavelength meter.
Kepadatan: Measure the density of the paint using an instrument such as a densitometer.
Tahan panas: through oven high temperature test, constant temperature and humidity test and other methods to test the high temperature resistance of the coating.
Pengujian kinerja resin light curing
Tahan terhadap cuaca: through artificial accelerated aging test or natural climate exposure test coating UV resistance, tahan korosi, dll..
Others: according to the specific type of light curing resin and test items, select the appropriate test method and equipment for testing, such as testing antistatic, antibacterial, dll..
